Embodiment 1:

As shown in the structure of FIG. 2, an embodiment of the present invention provides a dust removing module including a cylinder 10 having a plurality of vent holes. The cylinder 10 is filled with a plurality of dust suction units 2, and the cylinder 10 is provided with Agitating the agitator 5 of the plurality of dust suction units 2;

There are at least two different electronegativity between the cylinder 10 and the dust suction unit 2, or the dust suction unit 2 and the agitator 5, or the dust suction unit 2.

There are at least two different electronegativity between the dust suction units 2, which means that the surface materials of the plurality of dust suction units 2 have at least two kinds of electronegativity, and the surfaces of the one electronegativity material are positively charged after being separated from each other. Another type of electronegative material has a negative charge on its surface. Similarly, there are at least two different electronegativity between the cylinder 10 and the dust suction unit 2, and the surface material of the cylinder 10 and the dust suction unit 2 have at least two kinds of electronegativity. There are at least two different electronegativity between the dust suction unit 2 and the agitator 5, and the surface material of the dust suction unit 2 and the agitator 5 have at least two electronegativity.

Between the plurality of dust suction units 2, or between the dust suction unit 2 and the agitator 5, or between the dust suction unit 2 and the cylinder 10 There are two different electronegativity, that is, different vacuuming units 2 have different electronegativity, the vacuuming unit 2 and the cylinder 10 have different electronegativity, the vacuuming unit 2 and the agitator The three cases having different electronegativity may exist separately or in any combination, as long as a high-voltage electric field can be generated in the dust removing module under the agitation of the agitator 5. Under the stirring action of the agitator 5, the dust suction unit 2 moves back and forth, between the dust suction unit 2 or between the dust suction unit 2 and the cylinder body 10, the agitator 5, or generates friction and collision, thereby material having different electronegativity. Electron transfer occurs on the surface to form a high-voltage electric field. When the gas passes through the dust removal module, the dust in the gas is adsorbed.

The material of the surface of the cylinder in contact with the dust suction unit may be a conductor or an insulator.

Since the distance between the dust suction unit 2, the dust suction unit 2 and the cylinder 10 or the agitator 5 is small, and there is no tip discharge phenomenon, the gas is not ionized in the dust removal module and does not occur. Secondary pollutants such as ozone are not polluted.

In the specific use process, an agitator 5 may be disposed in the cylinder 10, or a plurality of agitators 5 may be disposed according to actual needs. For the larger volume of the cylinder 10, in order to ensure that the dust suction unit 2 can be agitated everywhere to prevent the occurrence of dead angles, a plurality of agitators 5 can be uniformly disposed in different areas to ensure that all the dust collection units 2 can be agitation. For example, in the case of the plate-like cylinder 10, the plurality of agitators 5 can be evenly distributed in a row. For the cylindrical cylinder 10, a plurality of agitators can be distributed on one or more circumferences and the like.

In a specific embodiment, the agitator 5 may include a screw rod or a stirring rod, and the screw rod is connected with a driving motor 41. The dust removing module further includes a rotating shaft connected to the agitator 5, and the agitator 5 extends along the length of the rotating shaft. The agitator 5 is connected to the drive motor 41 via a rotating shaft. As shown in Fig. 2, the center of the auger has a rotating shaft, and the rotating shaft is connected to different positions of the auger through a plurality of connecting rods to ensure the stability of the connection between the auger and the rotating shaft, and at the same time help to maintain the stability of the auger itself and prevent Deformation.

The connecting rod here can also be modified into a continuous spiral plate, that is, the rotating shaft and the auger are made into a structure similar to the auger, and the dust suction unit 2 is pushed to flip.

Specifically, the projection of the auger on a plane perpendicular to the longitudinal direction of the rotating shaft falls on the same circumference. That is, the auger is a spring-like structure, and the radius of each arc is the same, which is convenient for controlling the stirring range of each agitator 5.

The material of the auger may be any material having a certain strength, and may be a metal material such as aluminum, copper or stainless steel, or an insulating material such as nylon, polytetrafluoroethylene or engineering plastic having a certain mechanical strength. During the rotation of the auger to agitate the dust suction unit 2, noise is generated. In order to reduce noise, the surface material of the auger may be a flexible material such as plastic.

Further, the rotating shaft can be set vertically. As shown in FIG. 2, the agitator 5 is inserted in the vertical direction from the bottom of the casing 1 or the cylinder 10 to achieve agitation of the dust suction unit 2 in a cylindrical range centered on the rotation shaft; if the agitator 5 When there are a plurality of, the rotating shafts of the plurality of agitators 5 are disposed in parallel with each other. The drive motor 41 is coupled to the bottom end of the rotating shaft and is located outside the barrel 10 or the housing 1.

The side wall of the cylinder 10 has a cylindrical or polygonal structure. For the case where only one agitator 5 is provided, a cylindrical knot The structure is beneficial to ensure that all the dust suction units 2 can be stirred, avoiding dead angles and ensuring the purification effect. The cylindrical body 10 is only a preferred embodiment. According to actual needs, it may be provided in other polygonal or irregular shapes such as squares, and then a plurality of agitators 5 are provided to ensure the agitation effect.

The particle size range of the dust suction unit 2 may be 0.5 mm to 10 mm, and the aperture or slit width of the vent hole is smaller than the particle diameter of the dust suction unit 2. The vent hole needs to ensure that the gas can pass and prevent the dust suction unit 2 from leaking out, so the aperture or slit width of the vent hole is smaller than the particle size of the dust suction unit 2. The particle size of the dust suction unit 2 may be 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm;

When the dust suction unit 2 includes two types of dust suction units 2 having different electronegativity, the number of the two dust collection units 2 ranges from 0:1 to 1:1. That is, the electronegativity of all the dust suction units 2 is the same; or the dust suction unit 2 has two kinds of electronegativity, the number of the two dust suction units 2 may be equal or not equal, as long as it can function in the agitator 5 A high voltage electric field can be generated. For example, a plurality of vacuuming units may include a dielectric unit and a conductive unit, the outer surface of the dielectric unit being a dielectric material, and the outer surface of the conductive unit being a conductive material. Among them, the dielectric material and the conductive material have different electronegativity.

The dust suction unit 2 includes two types, one of which has an electronegativity greater than or less than the electronegativity of the other dust suction unit 2. The difference in electronegativity determines that the electrons can be switched between the different electronegative dust suction units 2, so that all the dust suction units 2 are charged, and the dust particles in the gas are adsorbed. The electronegativity of the dust suction unit 2 depends on the material constituting the dust suction unit 2. The high electronegativity material may be a polymer (polymer) such as PTFE, FEP, etc., and a low electronegativity material such as quartz or glass. Silicate materials, etc. The dust suction unit 2 may be solid particles or hollow particles made of a material, or may be solid particles or hollow particles coated with a material having a certain electronegativity, as long as the dust suction unit 2 is ensured during the rubbing process. The surface can be positively or negatively charged.

The electronegativity of the dust suction unit 2 is greater or smaller than the electronegativity of the cylinder 10. If all the vacuuming units 2 have the same electronegativity, that is, all the dust collecting units 2 are made of the same material, the dust collecting unit 2 is in the turning process due to the difference in electronegativity between the dust collecting unit 2 and the cylinder 10. The friction between the dust collecting unit 2 and the cylindrical body 10 is carried out by the frictional cleaning of the gas passing through the dust removing module. The cylinder 10 may be made entirely of a material having high electronegativity or low electronegativity, or may be coated with a material having high electronegativity or low electronegativity on the inner wall as long as vacuuming can be achieved. The transfer of electrons between the unit 2 and the cylinder 10 may be performed.

The embodiment of the present invention further provides a gas dust removing device, as shown in FIG. 2, which includes any dust removing module provided by the above embodiments.

As shown in the structure of FIG. 2, an air inlet 6 is disposed on one side of the dust removing module, and the gas is guided from the air inlet 6 to the dust removing module, and the purified gas passes directly through the cylinder 5 on the other side of the dust removing module. The upper air outlet 7 is discharged. Of course, it is also possible to swap the functions of the air inlet 6 and the air outlet 7, so that the gas passes through the dust removal module first, and then is discharged from the air outlet 7 or piped to a place where a cleaning gas is required.

In addition to the above structure, a structure as shown in FIG. 2 may be employed: the gas dust removing device further includes: a casing 1 having an air inlet 6 and an air outlet 7, the dust removing module being disposed in the casing 1, and the air inlet 6 coming in Gas is treated by dust removal module It is then discharged by the air outlet 7.

Under the stirring action of the agitator 5, the dust suction unit 2 rolls back and forth, between the dust suction unit 2 or between the dust suction unit 2 and the cylinder body 10, the agitator 5, or generates friction and collision, thereby material having different electronegativity. The surface generates electron transfer (friction electrification) to form a high-voltage electric field. When the gas passes through the dust removing module, the dust in the gas is adsorbed.

Since the distance between the dust suction unit 2, the dust suction unit 2 and the cylinder 10 or the agitator 5 is small, and there is no tip discharge phenomenon, the gas is not ionized in the dust removal module and does not occur. Secondary pollutants such as ozone, no pollution.

During the agitation of the dust suction unit 2 by the agitator 5, the dust suction unit 2 and the dust suction unit 2, the dust suction unit 2 and the cylinder body 10, the dust suction unit 2 and the agitator 5 rub and collide with each other, and the electrons are different. The transfer between the electronegative materials causes the vacuuming unit 2, the cylinder 10, or the agitator 5 to carry a positive or negative charge to form a high-voltage electric field; when the gas enters the dust removing module through the vent hole in the cylinder 10, the dust The particles are adsorbed by the electrostatically-charged dust suction unit 2, the agitator 5, or the cylinder 10 to purify the gas. The high-voltage electric field generated by this structure is maintained for several hours or even several days, and the electric charge generated by the agitation once is sufficient for dust filtration for a long period of time; therefore, the agitator 5 does not need to continue to work, but intermittently stirs. For example, stir well once in three days and stir for 30 minutes at a time. It is only necessary to start the agitator 5 once a day, and the gas dedusting device can work for a period of time to achieve the adsorption of dust in the gas. Only a small amount of electric energy is needed to realize the adsorption and purification of the gas, and the energy consumption is small. The purification cost is low; the gap between the dust suction units 2 is large, the gas can easily pass, and the resistance of the dust removal module to the gas flow is very small and negligible.

A fan 3 is connected to the air inlet 6 and/or the air outlet 7. The fan 3 is used to drive the gas through the casing 1, and is adsorbed and purified by the dust removing module in the casing 1, and finally the purified gas is discharged. The fan 3 can be connected to the air inlet 6, and the dusty gas can be sent to the dust removing device. It is also possible to connect the fan 3 at the air outlet 7 to accelerate the flow of the gas.

Specifically, the air inlet 6 is connected to the fan 3, and the air outlet 7 is formed by a plurality of air outlets formed in the casing 1. The air outlet may be a circular hole, a square hole, an oblong hole or a slit structure. As shown in FIG. 2, the fan 3 is disposed at the air inlet 6, and the outside air can be continuously sent into the casing 1. The air outlet 7 directly faces the indoor environment, so that only a plurality of outlets are required to be opened on the casing 1. The pores are sufficient, and the purified gas is directly discharged through the vent to the environment in which the casing 1 is located.

The housing 1 is used to define the flow direction of the gas, ensuring that the gas enters the housing 5 from the air inlet 6 on the side of the housing 5, and flows out from the air outlet 7 on the other side. The structure and shape thereof are variously selected, and are not limited herein. .

The present invention causes electron transfer between the dust suction units 2 or between the dust suction unit 2 and the cylinder 10 by agitation, so that the dust suction unit 2 or the cylinder 10 is electrostatically charged, thereby realizing adsorption of dust particles in the passing gas. During operation, it is not necessary to provide a corona ionized gas through an external high-voltage electric field to charge the dust particles and adsorb the charged dust, and mainly generate static electricity on the surface of the dust suction unit 2 or the cylinder 10 in the dust removing module by friction, and adsorb the gas. The dust particles thus achieve the purpose of purifying the gas. It is only necessary to periodically turn on the drive motor 41 for a period of time to achieve the adsorption of dust in the gas. The stirrer does not need to be opened for a long time, and only needs to provide a small amount of electric energy to realize the adsorption and purification of the gas. After the electric field is consumed, the electric field can be regenerated by starting the agitator 5 again, without replacing the dust removing module or the dust collecting unit 2, and the purification cost is low; between the dust collecting units 2 and the dust collecting unit 2 and the cylinder 10 There is no phenomenon that the gas is ionized, so there is no ozone generation phenomenon and no secondary pollution; there is a gap between the dust suction unit 2, the gas can easily pass, and the resistance of the whole device to the gas flow is generated. Very small and negligible.

The high-voltage electric field generated in the gas dust removing device can be maintained for several hours or even several days, and the electric charge generated by the agitation once is sufficient for the dust filtration for a period of time; therefore, the agitator 5 does not need to continue to work, and can be intermittently stirred. For example, stir once a day and stir for 30 minutes at a time. It only needs to start the agitator 5 to stir once a day, and the gas dedusting device can work for a period of time. The dust removal device only needs to provide a small amount of electric energy to realize the adsorption and purification of the gas, and the energy consumption is low and the purification cost is low.

Embodiment 2

The embodiment of the present invention further provides a drum type gas dust removing device, as shown in the structures of FIG. 3 and FIG. 4, the drum type gas dust removing device comprises a supporting unit, a housing rotatably connected to the supporting unit, and a driving shell The body rotates the driving unit 4; the housing comprises two end plates and at least two layers of cylinders connected between the two end plates and sequentially arranged from the inside to the outside, each of the barrels is provided with a vent hole, the housing The upper opening is provided with an air inlet or an air outlet communicating with the space inside the innermost cylinder; the adjacent cylinders are filled with a plurality of dust suction units 2; the drum type gas dust removal as shown in the structure of FIG. 3 and FIG. The housing 1 includes a first end plate 13, a second end plate 14, and an inner cylinder 11 and an outer cylinder 12 connected between the first end plate 13 and the second end plate 14, on the inner cylinder 11 a first vent hole 111 is provided, a second vent hole 121 is disposed on the outer cylinder body 12, and a plurality of dust suction units 2 are filled between the inner cylinder body 11 and the outer cylinder body 12; in FIGS. 3 and 4 Only the drum type gas dust removing device which is provided with two layers of the inner cylinder body 11 and the outer cylinder body 12 is shown, but in the specific use process, rolling The tubular gas dust removing device may further include a structure in which a plurality of cylinders sleeved between the inner cylinder 11 and the outer cylinder 12 are sleeved with three or four layers, five layers, and the like, and the outer cylinder 12 The second vent hole 121 forms an air outlet of the gas dust removing device. The specific structure is not limited to the structures shown in FIGS. 3 and 4.

There are at least two different electronegativity between each cylinder and the dust suction unit or the dust suction unit. Similarly, there is at least two different electronegativity between each cylinder and the dust suction unit, and the surface material of the cylinder body and the dust suction unit have at least two kinds of electronegativity.

When the casing rotates, a plurality of dust suction units 2 roll between adjacent two cylinder walls, friction between the dust suction unit 2, or between the dust suction unit 2 and the cylinder body, and the dust suction unit is further caused. 2 When the surface is electrostatically charged, the gas in the gas inlet 6 passes through the cylinder, and the dust in the gas is adsorbed by the electrostatic charging unit 2.

There are at least two different electronegativity between the cylinder and the dust suction unit 2 or the plurality of dust suction units 2, that is, the vacuuming unit 2 and the dust suction unit 2 have different electronegativity, and the dust suction unit 2 The two cases may have different electronegativity from the cylinder, and may be used singly or in any combination as long as a high-voltage electric field can be generated in the cylinder. The dust suction unit 2 moves back and forth with the casing 1 under the driving of the driving unit 4, and friction or collision between the dust suction unit 2 or the dust suction unit 2 and the cylinder body, thereby generating electron transfer on the surface of the material having different electronegativity. Forming a high voltage electric field When the gap between the dust collecting units 2 passes, the dust in the gas is adsorbed.

The driving unit 4 drives the housing 1 to rotate, and under the action of gravity, the dust suction unit 2 that rotates to a high position automatically rolls down, causing friction or collision between the dust suction units 2 and between the dust suction unit 2 and the cylinder body. Due to the different ability of different materials to bind electrons, electrons start to be transferred between the dust suction unit 2 or between the dust suction unit 2 and the cylinder 10 during friction and collision, so that the dust suction unit 2 is positively or negatively charged. Thereby, it is possible to adsorb dust particles in the gas and achieve the purpose of purifying the gas. Since the distance between the dust suction unit 2, the dust suction unit 2 and the cylinder is small, and there is no tip discharge phenomenon, the gas is not ionized in the cylinder 10, so there is no ozone generation. The phenomenon does not cause secondary pollution; as long as the driving unit 4 is driven to rotate the casing 1 for a period of time, the gas can be purified without replacing the casing 1 or the dust collecting unit 2, and the purification cost is low; the dust collecting unit 2 With a lot of gaps between them, the gas can easily pass between the dust suction unit 2 and the gap between the dust suction unit 2 and the cylinder body, and the resistance of the cylinder body and the dust suction unit 2 to the gas flow is very small, negligible .

In a specific embodiment, the particulate dust collecting unit 2 disposed between any two adjacent cylinders can completely cover the inner wall of the cylinder. In order to ensure that the dust suction unit 2 can fall down along with the rolling of the casing 1, the dust suction unit 2 between the cylinders does not need to be installed too full, so that the dust suction unit 2 can be displaced relative to the cylinder under the action of gravity; However, in order to ensure the purification effect, the gas is prevented from directly coming from the first vent hole 111 of the inner wall of the dust suction unit 2 to the second vent hole 121 of the outer wall of the dust suction unit 2, and the cleaning unit 2 should at least be cleaned. The cylinder that completely covers the inner side of the main body, that is, the dust suction unit 2 as shown in Fig. 3 should at least completely cover the inner side surface of the inner cylinder 10 to reduce the phenomenon that the gas is not purified and discharged.

As shown in the structure of FIG. 3 and FIG. 4, the casing has a two-layer cylinder of the inner cylinder 11 and the outer cylinder 12, and the outer cylinder 12 is sleeved outside the inner cylinder 11. This is only the simplest structure. The two-layer cylinder is filled with the dust suction unit 2 in the middle; the gas enters from the inner cylinder 11 and is adsorbed and purified by the dust suction unit 2, and then discharged from the outer cylinder 12 to complete the purification process. This is only the simplest embodiment. In order to improve the purification effect, the housing 1 can also adopt a multi-layered structure of three or four layers, and is not necessarily limited to this embodiment.

Each of the plurality of dust suction units 2 between any two adjacent cylinders may include two or more types of dust collection units, and the different types of dust collection units 2 have different electronegativity. A plurality of vacuuming units may include a dielectric unit and a conductive unit, the outer surface of the dielectric unit being a dielectric material, and the outer surface of the conductive unit being a conductive material. The electrons are transferred between the dust suction unit 2 and the dust suction unit 2 by friction and collision, and a high-voltage electrostatic field is generated. This is because the dust-collecting units 2 of different materials have different electronegativity, that is, the ability to bind electrons is different. When friction or collision occurs between the dust suction unit 2, electron transfer phenomenon occurs, and the surfaces of the dust suction unit 2 having different electronegativity are respectively positively and negatively charged; the greater the difference in electronegativity, the more It is prone to electron transfer. The electronegativity of the dust suction unit 2 depends on the material constituting the dust suction unit 2. The high electronegativity material may be a polymer (polymer) such as PTFE, PVDF, etc., and a low electronegativity material such as quartz or glass. Silicate materials, etc.

The materials of the plurality of dust suction units 2 between any two adjacent cylinders may be the same, and the dust suction unit 2 is connected thereto. The cylinders that are touched have different electronegativity. When the dust suction unit 2 and the cylinder body have different electronegativity, or the dielectric constant is different, the cylinder body rolls to cause a frictional collision between the dust suction unit 2 and the cylinder body, so that the surface of the dust suction unit 2 and the cylinder body The surface generates a large amount of electric charge to form a high-voltage electrostatic field, and the dust is adsorbed when the gas passes, thereby achieving the purpose of adsorbing dust particles in the gas; since the distance between the dust suction unit 2 and the cylinder is small, and there is no tip discharge phenomenon, There is no phenomenon that the gas is ionized between the dust suction unit 2 and the cylinder, and no ozone is generated, and secondary pollution is not caused. As to what kind of material is used for the dust suction unit 2 and the wall of the cylinder to have different electronegativity, reference may be made to the foregoing description of high electronegativity and low electronegativity, and details are not described herein again.

In addition, the dust suction unit 2 may be solid particles or hollow particles made of a material, or may be solid particles or hollow particles coated with a material having a certain electronegativity, as long as the vacuum is ensured during the friction process. The surface of the unit 2 can be positively or negatively charged. The cylinder may also be made of a material having a certain electronegativity, or a surface of the cylinder coated with a certain electronegativity, which can be flexibly designed according to actual needs and procurement cost of the material.

An air inlet 6 or an air outlet 7 communicating with the space inside the innermost cylinder is disposed on one of the end plates. Each layer of the cylinder needs to be provided with a vent hole. As shown in the structure of FIG. 3, the drum type gas dust removing device has only one air inlet or air outlet, and is called a single side air inlet and outlet drum type gas dust removing device. Taking the air inlet 6 provided on the first end plate 13 as an example, the gas flows from the air inlet 6 to the innermost cylinder, that is, the space inside the inner cylinder 11, and then the first from the inner cylinder 11 The vent hole 111 gradually spreads outward, and in the case of the multi-layer cylinder, sequentially passes through the cylinder-vacuum unit 2-cylinder-vacuum unit 2... until from the outermost cylinder wall, that is, the outer cylinder 12 The second vent hole 121 is discharged, and the gas purification is completed. Of course, if the air outlet 7 is provided on the first end plate 13, the gas flows in the opposite direction, flowing from the outermost cylinder to the innermost cylinder.

As shown in the structure of FIG. 4, the first end plate 13 and the second end plate 14 of the casing 1 are respectively provided with an air outlet 7 or an air inlet 6 which communicates with the space inside the innermost cylinder wall-inner cylinder 11. . The first end plate 13 and the second end plate 14 at both ends of the drum type gas dust removing device are respectively provided with an air inlet 6 or an air outlet 7, which is called a double-side air-discharge type drum type dust removing device. In use, the first end plate 13 and the second end plate 14 are both air inlets 6 or both of the air outlets 7 to ensure that the gas can be adsorbed and purified by the dust suction unit 2 with static electricity passing through the plurality of cylinder walls in sequence.

In order to increase the gas purification efficiency, the air inlet 6 or the air outlet 7 is connected to the blower 3. The setting of the fan 3 can ensure the continuous flow of the gas and increase the volume of the purified gas per unit time.

The driving unit 4 may be a driving motor 41 and a transmission mechanism 42. The transmission mechanism 42 is a belt transmission mechanism 42 composed of a belt and a pulley, a chain transmission mechanism 42 composed of a chain and a sprocket, or a gear transmission mechanism 42 composed of a gear. The type of the transmission mechanism 42 can be flexibly selected as long as the entire housing 1 can be rotated; as shown in FIG. 3 or FIG. 4, the drive motor 41 and the housing 1 are driven by gear engagement at one end of the housing 1. It is also possible to switch to the belt transmission mechanism 42 or the chain transmission mechanism 42, which can be flexibly selected according to the size of the installation space.

In order to simplify the structural design, each of the cylinders is a coaxially disposed cylindrical structure. As shown in FIGS. 3 and 4, the inner cylinder 11 and the outer cylinder 12 are coaxially disposed, and the cylinder can be rotated about a horizontal central axis of rotation. . The cylindrical structure of the coaxial arrangement can ensure the stability of the center of the whole casing, and the casing is not easy to shake during the rotation process, and the driving motor 41 during the rotation of the casing The force is relatively stable, which is beneficial to prolonging the service life of the drive motor 41 and the housing; the rotation speed is stable, the dust suction unit 2 continues to roll, and the dust suction unit 2 is not concentrated due to sudden changes in speed, and gas is directly passed through. The phenomenon of being adsorbed and purified to ensure the adsorption purification effect.

In order to achieve the intended purpose of purification, the rotation speed of the casing should not be too high, for example, it should not exceed 60r/min. Otherwise, the dust collection unit 2 will have a centrifugal phenomenon, which will not cause the collision and friction between the dust suction unit 2 and the cylinder. The purpose of purifying the gas is achieved; of course, the lower the rotational speed, the lower the power consumption. The rotation of the housing does not necessarily have to be continuously rotated, because the surface charge of the dust suction unit 2 can be maintained for a long period of time, during which time the dust in the gas is adsorbed; therefore, it can be intermittently opened. The driving motor 41 rotates the housing intermittently, for example, once a day, once for 10 minutes, to meet the purification requirement of one day, and the power consumption is very small.

The vent holes may be round holes, square holes, oblong holes or slit structures. Here, just a few preferred structures are listed, and other structures capable of achieving ventilation may also be employed.

The particle size range of the dust suction unit 2 may be 0.5 mm to 10 mm, and the aperture or slit width of the vent hole is smaller than the particle diameter of the dust suction unit 2. The vent hole has to ensure that the gas can pass and prevent the dust suction unit 2 from leaking out, so the aperture or slit width of the vent hole is smaller than the particle size of the dust suction unit 2. The particle size of the dust suction unit 2 may be 0.5 mm, 1 mm, 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm.

When there are two different electronegativity between the dust suction units 2, the number of the two dust suction units 2 ranges from 0:1 to 1:1. That is, either the electronegativity of all the dust suction units 2 is the same, or the plurality of dust suction units 2 have two kinds of electronegativity, and the number of the two dust suction units 2 may be equal or not equal, as long as it can rotate in the casing. A high voltage electric field can be generated in the process.

The following is an example of a drum type gas dust removing device with two sides in and out of the air, and the working process of the above-mentioned drum type gas dust removing device is explained in detail: as shown in FIG. 4, it is assumed that the first end plate 13 is provided with an air inlet 6, The cylinder also has only two layers of the inner cylinder 11 and the outer cylinder 12, and the outer ring of the air inlet 6 at the first end plate 13 near the side of the drive motor 41 is a gear, and the main shaft of the drive motor 41 is also The gear motor is provided, and the driving motor 41 drives the whole casing to rotate through the gear meshing structure. The dust collecting unit 2 on the upper part of the casing is no longer balanced under the rotation of the casing, and starts to fall under the action of gravity, and the vacuum is lowered below. The unit 2 and the inner cylinder 11 and the outer cylinder 12 generate friction and collision, and the dust suction unit 2 is charged; the outside air is pumped by the fan 3 to the air inlet 6 at both ends of the inner cylinder 11 and reaches the space inside the inner cylinder 11; Since there is no vent hole on the end plates on both sides, the gas can only enter the space between the inner cylinder 11 and the outer cylinder 12 from the first vent hole 111 on the inner cylinder 11, and the electrostatic suction unit 2 contact, the dust in the gas is adsorbed by the dust suction unit 2, and the purified gas The second vent hole outer cylinder 12112 out emissions. Of course, the thickness of the annular space between the inner cylinder 11 and the outer cylinder 12 can be set according to actual needs to ensure an optimal purification effect without causing great resistance to gas.

Embodiment 3

As shown in FIG. 5, an embodiment of the present invention provides a dust removal module, which includes a sleeve from the inside to the outside. At least two cylinders, and a plurality of dust suction units 2 filled between adjacent cylinders, each of which is provided with a vent hole; wherein at least one of the cylinders is connected with a driving unit for driving the rotation thereof As shown in the structure of FIG. 5, the dust removing module includes an inner cylinder 11 and an outer cylinder 12 which are sequentially disposed from the inside to the outside. The inner cylinder 11 and the outer cylinder 12 are filled with a plurality of dust suction units 2 and inner cylinders. The first vent hole 111 is defined in the body 11, the second vent hole 121 is opened in the outer cylinder 12, and the driving unit 4 is connected to the outer cylinder 12;

There is at least two different electronegativity between the at least one cylinder and the dust suction unit 2, or the dust suction unit 2. Similarly, there is at least two different electronegativity between the cylinder and the dust suction unit 2, and the surface material of the cylinder and the dust suction unit 2 has at least two kinds of electronegativity. The electronegativity is different, and the ability of the material to bind electrons is different, such as the cylinder of the metal material and the dust suction unit of the dielectric material.

At least one of the cylinders rotates to cause friction and collision between the dust suction units 2 or between the dust suction unit 2 and the cylinder body, thereby electrostatically charging the surface of the dust suction unit 2, and the gas entering through the air inlet 6 passes through In the case of the plurality of dust suction units 2, the dust in the gas is adsorbed by the static electricity suction unit 2.

The gas is purified from the innermost cylindrical body-inner cylinder 11 through the entire dust removing module, and then discharged through the outermost cylinder-outer cylinder 12, which of course may be reversed. The cleaning principle is as follows: the driving unit 4 drives the corresponding cylinder to rotate, and the dust suction unit 2 in contact with the cylinder starts to move under the action of friction and gravity, so that the plurality of dust suction units 2, the dust suction unit 2 and the cylinder Friction and collision occur between the bodies. Due to different electronegativity, the ability of different materials to bind electrons is different. During the friction and collision, electrons start to transfer between the dust suction unit 2 or between the dust suction unit 2 and the cylinder. The vacuuming unit 2 is brought positively or negatively to form a high-voltage electrostatic field, thereby adsorbing dust particles in the gas, thereby purifying the gas. Since the distance between the dust suction unit 2 and between the dust suction unit 2 and the cylinder is short, and there is no tip discharge phenomenon, there is no phenomenon that the gas is ionized, so there is no ozone generation phenomenon. Causes secondary pollution; only needs to rotate the cylinder to generate an electrostatic field, so there is no need to replace the dust suction unit, and the purification cost is low; the gap between the dust suction units 2 is large, and the gas can be easily removed from the dust suction unit 2 Passing through the gap between them, the resistance of the dust suction unit 2 to the gas flow is very small.

In a specific embodiment, in order to ensure that as many dust suction units 2 as possible can be charged, each cylinder can be obtained by sequentially numbering a plurality of cylinders sequentially distributed from the inside to the outside in order from the inside to the outside or from the outside to the inside. The sequence number of the body, wherein the cylinder whose sequence number is odd or even is connected with a driving unit that drives the rotation thereof. Therefore, the cylinder body is in a state of being fixed-rotating-fixing-rotating from the inside to the outside, and when the movement unit 2 has a large movement range, the purpose of friction between the cylinder and the fixed cylinder can be achieved. It is ensured that all the dust suction units 2 can participate in the adsorption process to improve the adsorption capacity. In this embodiment, only a part of the cylinder rotates, which can save electric energy.

In order to improve the adsorption effect of the dust suction unit 2, each of the cylinders 10 is connected to a drive unit 4 that drives its rotation. In order to further enhance the friction and collision degree of the dust suction unit 2, all the cylinders are arranged in a rotatable structure, so that all the dust suction units 2 can be fully engaged, and some dust collection units are not caused by the cylinder fixing. 2 The phenomenon of immobility improves the utilization rate of the dust suction unit 2.

Specifically, the directions of rotation of adjacent cylinders are opposite. On the basis that all the cylinders are rotated, in order to avoid the movement of the adjacent cylinders in the same direction, the dust suction unit 2 between the cylinders moves integrally with the cylinder body, and the purpose of friction between the dust suction unit 2 and the cylinder body cannot be achieved. The adjacent cylinders are arranged to rotate in opposite directions, thereby avoiding the occurrence of the above-mentioned unfavorable phenomena, ensuring that each of the dust collection units 2 can participate in the process of adsorption purification, and improve the adsorption capacity of the entire dust removal module.

Further, the rotational angular velocities of the adjacent cylinders are made different. Similarly, on the basis of the rotation of all the cylinders, when the angular velocities of the adjacent cylinders are the same, the dust suction unit 2 between the two cylinders moves integrally with the two cylinders, and the dust suction unit 2 does not generate friction with the cylinder, in order to avoid this phenomenon, the angular velocity of the rotation of the adjacent cylinders is set to a different value, that is, there is an angular velocity difference between the two, so that the dust suction unit between the two 2 can move, cause friction between the dust suction unit 2, the dust suction unit 2 and the cylinder, and participate in the adsorption purification process.

Specifically, the dust removing module may include only two cylinders of the inner cylinder 11 and the outer cylinder 12, and the outer cylinder 12 is sleeved on the outer side of the inner cylinder 11; as shown in FIG. 5, this is the simplest structure. In the embodiment, only the inner and outer two-layer cylinders are provided, and the dust suction unit 2 is disposed in the middle; one of them can be selected to be rotated, and the other is fixed; or two simultaneous rotations, preferably the opposite rotation directions, are optimal.

In the dust removing module described above, the cylinder connected to the driving unit 4 may be intermittently rotated or continuously rotated, and the rotating speed may be slow.

The rotation speed of the cylinder may not be too high, otherwise it is easy to rub to generate a large amount of heat; of course, the lower the rotation speed, the lower the power consumption. The rotation of the cylinder does not necessarily have to be continuously rotated, because the surface charge of the dust suction unit 2 can be maintained for a long period of time, during which time the dust in the gas is adsorbed; therefore, it can be intermittently opened. The motor 3 rotates the cylinder intermittently, for example, once every three days, once for 30 minutes, it can meet the three-day purification demand, and the power consumption is very small.

More complicated, the dust removal module may include three cylinders, and may also include four, five, six, and the like. When three layers of cylinders are provided from the inside to the outside, the three-layer cylinder may include the inner cylinder. a cylinder 11, an intermediate cylinder and an outer cylinder 12, a dust suction unit 2 is disposed between the inner cylinder 11 and the intermediate cylinder, and a dust suction unit 2 is disposed between the intermediate cylinder and the outer cylinder 12; Set to the middle of the cylinder rotation, the inner and outer two fixed; or any two rotation, one does not move; or three cylinders are rotated; when the two adjacent cylinders are rotated, you can control the angular velocity Different or different ways to ensure that the dust suction unit 2 between the two cylinders can be rubbed and collided, and the dust suction unit 2 is charged to participate in the adsorption process. In the case of the multilayer cylinder, the gas sequentially passes through the cylinder-vacuum unit 2-cylinder-vacuum unit 2... until it is discharged from the outermost cylinder, and the gas purification is completed.

The drive unit 4 may include a drive motor 41 and a transmission mechanism 42. The transmission mechanism 42 may be a belt transmission mechanism 42 composed of a belt and a pulley, a chain transmission mechanism 42 composed of a chain and a sprocket, or a gear transmission mechanism 42 composed of a gear. The type of the transmission mechanism 42 can be flexibly selected as long as at least one cylinder can be rotated.

The outer cylinder 12 can be made of a conductor or an insulating material, and the dust suction unit 2 between any two adjacent cylinders includes two types, wherein the vacuuming unit 2 has an electronegativity greater or less than the other. The electronegativity of the dust suction unit 2. The outer cylinder 12 is insulated and does not participate in the electron transfer process, and the outer cylinder 12 may be made of nylon, polytetrafluoroethylene, acrylic, engineering plastic or metal. The electron transfer between the dust suction unit 2 and the dust suction unit 2 can generate static electricity, because the dust suction units 2 of different materials have different electronegativity, that is, the ability to bind electrons is different, when the dust suction unit 2 When friction or collision occurs, electron transfer phenomenon occurs, and the surface of the dust suction unit 2 with different electronegativity is positively and negatively charged respectively; the larger the difference of electronegativity, the more likely the electron transfer phenomenon occurs. The electronegativity of the dust suction unit 2 depends on the material constituting the dust suction unit 2. The high electronegativity material may be a polymer (polymer) such as PTFE, FEP, etc., and a low electronegativity material such as quartz or glass. Silicate materials, etc.

The electronegativity of the outer cylinder 12 may also be greater or less than the electronegativity of the dust suction unit 2 in contact therewith. Similarly, when the materials of the dust suction unit 2 are the same, the dust suction unit 2 and the cylinder body are respectively made of materials having different electronegativity, and electron transfer between the dust suction unit 2 and the cylinder body 10 can be performed to make suction. The surface of the dust unit 2 is electrostatically charged to achieve the purpose of adsorbing dust particles in the gas. For the material used, reference may be made to the foregoing description, and details are not described herein again.

In addition, the dust suction unit 2 may be solid particles or hollow particles made of a material, or may be solid particles or hollow particles coated with a material having a certain electronegativity, as long as the vacuum is ensured during the friction process. The surface of the unit 2 can be positively or negatively charged. The cylinder may also be made entirely of a material having a certain electronegativity, or a surface coated with a material having a certain electronegativity, which can be flexibly designed according to actual needs and the procurement cost of the material.

The vent hole provided on the cylinder may be a circular hole, a square hole, an oblong hole or a slit structure. Here, only a common structure is exemplified, and other structures capable of achieving ventilation may also be employed.

At the same time, the particle size range of the dust suction unit 2 is 0.5 mm to 10 mm, and the aperture or slit width of the vent hole is smaller than the particle diameter of the dust suction unit 2. The vent hole has to ensure that the gas can pass and prevent the dust suction unit 2 from leaking out, so the aperture or slit width of the vent hole is smaller than the particle size of the dust suction unit 2.

When there are two different electronegativity between the dust suction units 2 between adjacent cylinders 10, the number of the two dust suction units 2 ranges from 0:1 to 1:1. That is, the electronegativity of all the dust suction units 2 is the same; or the dust suction unit 2 has two kinds of electronegativity, and the number of the two dust suction units 2 may be equal or not equal, as long as the cylinder can be rotated. A high voltage electric field can be generated. The vacuum unit may include a dielectric unit and a conductive unit, the outer surface of the dielectric unit is a dielectric material, and the outer surface of the conductive unit is a conductive material. The conductive material may be selected from a conductive material such as a metal.

Each cylinder is coaxially arranged. The coaxial arrangement can ensure that the distance between adjacent cylinders is equal, the resistance to the motor 3 during the rotation of the cylinder is relatively stable, and the force of the cylinder is relatively stable, which is beneficial to prolong the service life of the motor 3 and the cylinder. .

On the basis of the dust removing module of the third embodiment, the embodiment of the present invention further provides a cartridge type gas dust removing device, which comprises a casing 1 having an air inlet 6 and an air outlet 7, and a housing 1 is provided with any one of the dust removing modules provided in the above embodiments, one of the air inlet 6 and the air outlet 7 is in communication with the space inside the innermost cylinder-inner cylinder 11, and the other is the outermost cylinder. - the space outside the outer cylinder 12 is connected;

The rotation of the cylinder of the dust removing module causes friction and collision between the dust suction units 2 or between the dust suction unit 2 and the cylinder 10 When the collision occurs, the surface of the dust suction unit 2 is electrostatically charged, and when the gas at the air inlet 6 passes through the dust removal module, the dust in the gas is adsorbed by the electrostatic suction unit 2 with static electricity.

All the dust collection units 2 can participate in the movement, and the frictional unit 2, the dust suction unit 2 and the inner cylinder body 11, the dust suction unit 2 and the outer cylinder body 12 rub and collide with each other to realize electron transfer and suction. The dust unit 2 carries a positive or negative charge; the fan 3 sends the outside air to the air inlet 6, and the gas gradually passes through the inner cylinder The side wall and the top of the body 11 enter the gas dust removing module, and the dust particles in the gas are adsorbed by the charged dust collecting unit 2 to be purified; the purified gas is discharged from the side wall and the top of the outer cylinder 12, and respectively The air outlet at the air outlet 7 of the casing 1 is discharged for use by the user.
