The present invention relates to an air purifying apparatus used for repurifying air discharged from a waste incinerator, or installed in a ventilation facility of a workplace where dust, toxic gases, and odors are severely generated, and more specifically, dust (dust). Combustion heaters for burning substances harmful to the human body, such as odors and toxic gases, and purification tanks for purifying the air passing through the combustion heaters through water washing, each function being improved compared to the existing apparatus, and additionally The present invention relates to an industrial air purifying apparatus capable of doubling the purifying effect by further adding phosphorus purifying means.

As it is well known, incineration equipment of industrial waste does not completely combust flame retardant waste such as synthetic resin or drinking waste when incinerated, and incineration residues are generated a lot. It is a major cause of pollution. Of course, the arrangement of expensive incinerators can significantly reduce the non-combustion rate due to the improvement of combustion efficiency, but the cost aspects must be taken into consideration.

Therefore, most companies install a separate air purifier on the outlet side instead of using a low-cost incinerator, so that clean air can be discharged. The problem is that most of the air purifiers used here are filter type. Due to the characteristics of the incinerator, which emits a lot of foreign substances, it is inconvenient to use and requires a lot of maintenance costs because the filter has to be washed or replaced frequently, and the filter-type air purifier has some effects on the filtration of dust. But it has the disadvantage of being vulnerable to odor removal. Therefore, a countermeasure against this is required.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, the main object of the present invention is installed in the exhaust inlet of the waste incineration device or the ventilation facility of the workplace to completely remove the harmful substances such as dust, odor, toxic gas, etc. An industrial air purifying apparatus for erasing is provided.

Industrial air purifying apparatus of the present invention has a great purification effect according to the combination of a combustor for burning dust and odor, a purification tank for eliminating burned ash and odor and other functional filters. As almost all purifying actions are performed by the combustor and the septic tank, the additionally installed filter can enjoy the convenience of use because there is no need to change or clean the filter frequently because only a small amount of foreign substances are filtered out.

Industrial air purifier according to the present invention is used for the final purification of the harmful substances remaining in the air discharged from the waste incinerator, or is installed in the ventilation facilities of the workplace that generates dust, toxic gas, odor. .

The industrial air purifying apparatus of the present invention is largely divided into two embodiments.

First, the air purifying apparatus of the first embodiment has a suction pipe 10 connected to an outlet of a waste incineration apparatus or a ventilation facility of a workplace as shown in FIGS. 1 to 4. In this case, the suction pipe has a bellows shape to enable the change of direction and the length of the suction pipe, so that the suction pipe can be easily connected to a fixed facility such as an outlet of an incinerator or a ventilation facility of a workplace.

In addition, an electrostatic precipitator 20, in particular a cyclone electrostatic precipitator, is installed inside the suction pipe 10 to collect dust flowing through the suction pipe. Here, the cyclone electrostatic precipitator uses centrifugal force to give the air containing dust greater acceleration than gravity, so that the separation speed between dust and air becomes greater than gravity, so that air and foreign matter are separated. Here, the cyclone electrostatic precipitator is taken as an example, but the present invention is not limited thereto, and other dust precipitators may be applied if dust can be collected.

In addition, a combustion heater 30 is installed at a next position of the electrostatic precipitator 20 to combust the remaining dust and the odor component contained in the air. The combustion heater 30 has a labyrinth structure so that air is temporarily stagnated at the combustion heater, thereby increasing the contact time between the combustion heater and the air, thereby increasing the combustion efficiency.

In more detail, the combustion heater 30 may be manufactured in a plurality of plate shapes and arranged in a zigzag shape on the air flow path so that the air flows in a zigzag shape when passing through the combustion heater. Since the air flow path in the combustion heater is zigzag, the residence time of the air is longer than that of the straight flow path, so it is possible to secure a time for burning dust and odor components contained in the air, thereby improving combustion efficiency.

The combustion heater 30a of another example includes a heater case 30b, a baffle 30c disposed in a zigzag shape inside the heater case, and a plurality of unit heaters 30d disposed on the respective baffles, as shown in FIG. You can also configure). This combustion heater is burned a number of times by unit heaters disposed on each baffle each time the air passes through the baffles, so that good combustion efficiency can also be obtained.

In addition, the combustion heater (30a) is preferably to be able to adjust the heating temperature by the user to install a temperature control switch 31 to enable the temperature control according to the installation situation rather than always maintaining a fixed temperature. For example, when there is little dust and odor, the temperature of the combustion heater is reduced to reduce power consumption. On the contrary, when there is a lot of dust and odor, the combustion heater is used according to the surrounding conditions by increasing the temperature of the combustion heater to increase combustion efficiency. Made it possible.

Here, it is preferable to install a heat shield plate or a heat insulating plate 32 on the inner wall or the outer wall of the heater case 30b so as to prevent the heating heat from being conducted to another place or to prevent the heating heat from falling due to the external temperature. .

In addition, a blowing fan 40 and a fan motor 41 serving to suck and blow air are installed at the next positions of the combustion heaters 30 and 30a. In this case, the fan motor 41 is preferably installed outside the tubular body 50 in consideration of the fact that the heating heat is conducted may cause a shortening of life or failure. At this time, since the blowing fan 40 and the fan motor 41 are in a throttled state, a means for connecting them is required, and a power transmission medium such as (bevel) gear 42 or a belt plays a role.

In addition, a mesh body 60 for collecting the combusted ash is installed at a next position of the blower fan 40 and the fan motor 41, and more specifically, at the outlet side of the tube 50. This mesh body is preferably made detachable from the tube body 50 to enable cleaning.

In addition, a purifying water tank 70 filled with purified water is installed at a next position of the mesh body 60. As shown in FIG. 4, the purified water tank is fitted with a microtubular tube 71 so as to be obtained in a state where air is finely branched at the lower end of the inlet 70a. This microtubule can minimize the noise generated when bubbles are blown out by miniaturizing bubbles when air enters the purified water, and also requires high force to obtain air into the purified water. The fan must be applied. However, if the air is divided and obtained, it is possible to use a relatively low pressure / low capacity blowing fan, thereby reducing the cost.

In addition, a plurality of diaphragms 72 are formed or installed on the inner wall of the purification tank 70 to prevent vortices. This diaphragm divides the space of the purification tank and suppresses the diffusion of the vortex, thereby reducing the water flow (vortex) noise.

In addition, a freezing heater 73 is installed on the wall surface of the purification tank 70. Since the septic tank may be installed outdoors in some cases, the septic tank filled with the inside of the septic tank freezes due to the low temperature outdoor temperature in winter so that the septic tank may rupture. However, since there is no need to operate the freezing prevention heater other than the winter season, it is preferable to provide an on / off switch 74 for the selective operation of the heater.

In addition, one side of the purified water tank 70 is provided with a purified water injection valve 75 for automatically injecting purified water, and the other side is provided with a purified water discharge valve 76 for discharging purified water. Here, a water level sensor 77 is installed inside the purified water tank 70 to detect whether the purified water is at an appropriate level. The water level sensor is electrically connected to the purified water injection valve 75 to detect the water level. According to the detection result of the sensor can be applied to the automatic level control system to automatically open and close the purified water injection valve.

In addition, the purification tank (70) is provided with an opening and closing door 78 on one side, the bottom surface is preferably formed to be inclined downward toward the opening and closing door (78). This is a kind of convenience facility that allows the sediment to be concentrated on the open / close door side so that the sediment can be collected more easily by opening the open / close door.

In addition, on the water surface of the purification tank (70), a holding and adsorption cloth (80) for adsorbing the oil floating on the water surface is floated. This oil-absorbing cloth is used to purify the purified water by adsorbing the oil floating on the water while being filtered by the purified water.

In addition, a purification agent such as a ceramic ball 90 for filtration of the purification water for a long time is introduced into the purification tank 70 in a submerged state. If there is no such purification agent, the purified water must be replaced from time to time, which is inconvenient for the user, and water consumption is also increased.

In addition, a discharge pipe 100 through which the purified air is discharged is connected to the outlet 70b of the purification tank 70. At this time, a single or multiple filtration filter 110 is installed on the discharge pipe to finally purify the discharged air. Here, the filtration filter may be applied in various ways, for example, a carbon filter, a pre-filter, and other special filters may be applied.

The operation of the industrial air purifying apparatus of the first embodiment configured as described above will be omitted since it is described in the process of describing the configuration.

Next, the industrial air purifying apparatus of the second embodiment is provided with an outer case 200 having a opening door 201 on its front surface as shown in FIGS. 5 to 9. Here, the air inlet 202 is formed on the upper plate of the outer case is connected to the flexible suction pipe 204. In addition, an air outlet 203 is formed on one side of the outer case 200 to discharge the purified air.

In addition, a combustor 210 communicating with the suction pipe 204 is installed inside the outer case 200. The combustor has a function of burning dust and odor as mentioned in the first embodiment, and thus has a heating element therein. Here, the combustor 210 is sealed by the removable lid 211 and the partition wall 212 is installed in the transverse direction therein, the combustor case 215 partitioned into first and second spaces 213 and 214, and the first And a heater 216 provided in any one of two spaces. At this time, the partition 212 is shorter than the width b ₁ of the combustor case 215 (b ₁ > b ₂ ), so that the first space 213 and the second space 214 are in communication with each other. have. Therefore, the air introduced into the combustor 210 is first introduced into the space in which the heater 216 is installed, is burned, and moves over the partition 212 to another space. In this process, the air is moved by the partition 212. As the flow path of the gas becomes longer, the stagnation time of air in the combustor case 215 can be ensured. As a result, the stagnation of air increases the combustion time by increasing the contact time between the heater 216 and the air.

In addition, the heater 216 is an electric heater operated by electricity, and has a configuration in which a heat radiation fin is formed on the surface of the tube body in which the heating wire is built, and is generally bent in a “U” shape.

In addition, the combustor is preferably provided with a temperature control switch to enable temperature control. The reason is the same as in the first embodiment described above.

In addition, a first filter 220 is installed at the air outlet 210a of the combustor 210 to filter foreign matter contained in the combusted air. This first filter is made by mixing activated carbon with limonite (FeOOH nH 2 O). Basically, activated carbon and limonite have deodorizing performance and heavy metal filtration, and especially limonite has an excellent effect on removing nitrate nitrogen.

In addition, a blowing fan 230 for sucking and blowing air and a fan motor 231 are installed at a next position of the first filter. Here, the blowing fan 230 is a sirocco fan is used, the fan motor 231 is supported on the upper surface of the purification tank to be described later by the mount 233 while being installed outside the fan housing 232. As the fan motor 231 is located outside the fan housing, it is possible to prevent the fan motor from being heated by the air warmed to a high temperature while passing through the combustor. In addition, the blower fan 230 has to be applied to the blower fan having a relatively strong blowing pressure because the air must be injected into the purified water of the purified water tank to be described later, in terms of numerical value of about 180mmAg blowing pressure is required. .

And, the lower side of the blowing fan 230 is provided with a purification tank filled with purified water at a predetermined level so that the air blown by the blowing fan is injected into the water. At this time, the air inlet port (240) of the inlet (240a) of the purified water tank 240 is provided with an air separator 250 for finely injecting the air.

The air separator 250 has a configuration in which a pore plate 251 having a plurality of pores 251a and a micro tube 252 communicating with pores are formed on one side of the pore plate. Accordingly, when the air blown from the blower fan 230 reaches the air separator 250, the air is branched into each of the microtubes 252 and obtained as the purification water of the purification tank 240. Therefore, it is possible to obtain air even when using a relatively low pressure blower compared to the case where there is no air subdivision.

In addition, the purification tank 240 is preferably provided with a heater for preventing freezing (not shown). The reason is the same as that of the first embodiment.

In addition, one side of the purified water tank 240 is provided with a purified water injection valve (not shown) for automatically injecting purified water, the other side is preferably provided with a purified water discharge valve for discharging the purified water. In addition, a water level sensor is installed in the purified water tank 240 to detect whether the purified water is at an appropriate level. The water level sensor is electrically connected to the purified water inlet valve according to the detection result of the water level sensor. It is more preferable to apply an automatic water level control system for automatically opening and closing the purified water injection valve.

In addition, the air bubble grinder 260 is installed in a state of being submerged in the purification tank 240. The air bubble crusher 260 is constructed between two flat wire meshes 261 and 262 with a compact (not necessarily dense) crystal 263 which is effective in purifying water such as jade. The air bubble grinder 260 is microbubble while passing through the air bubble grinder 260 when the air passing through the microtubule 252 rises, thereby purifying foreign matter by washing the air in this process. .

In addition, a second filter 270 is installed at the outlet side 240b of the purification tank 240 to finally filter foreign substances contained in the air passing through the purification tank. In this case, a scoria filter is applied to the second filter. The scoria filter has a function of adsorbing heavy metals contained in air and eluting minerals.

In addition, a bellows-type discharge pipe 280 is installed at the outlet side 240b of the purification tank 240 to discharge the purified air passing through the second filter 270 to the outside of the outer case 200.

As described above, the industrial air purifying apparatus of the present invention is equipped with a large purifying effect such as a combustor and a septic tank, so basically, the purifying efficiency is excellent, and it is not removed by a separate filter. By doing so, the air purification effect is great. Incidentally, it is easy to use due to the long cycle of cleaning or changing the filter, and the maintenance is easy because the combustor or the septic tank is not frequently broken or the unit has a short life.
