A fine scrubber device according to a preferred embodiment of the present invention relates to a scrubber device, which is installed below the main body 1 and the main body 1 to store the liquid in the reservoir 10 and one side of the main body 1. It includes a gas moving tube 20 extending from one side of the main body 1 to the reservoir 10 so that the introduced gas is moved to the reservoir 10.

That is, the fine scrubber apparatus which concerns on this invention includes the main body 1, the reservoir 10, and the gas movement pipe 20. As shown in FIG.

At this time, the gas moving pipe 20 is a pipe for guiding the gas containing fine dust, harmful dust (fume), droplets (mist) and harmful gas to move to the reservoir 10, the gas is a gas moving pipe It contacts with the washing | cleaning liquid of the reservoir 10 through the 20.

At this time, in the gas flow pipe 20, the introduced gas is rotated in a vortex form, that is, to form a spiral vortex (vrtex) to be in contact with the cleaning liquid of the reservoir (10).

That is, the gas flow pipe 20 is configured such that the introduced gas forms a spiral in the form of a spiral and is discharged into the cleaning liquid of the reservoir 10.

In this case, a separate rotational power configuration for forming a spiral vortex of the inflow gas is not added to the gas flow pipe 20 constituting the fine scrubber device according to the present invention. That is, the gas flow pipe 20 is configured such that the introduced gas forms a spiral vortex by the structural feature of the gas flow pipe 20. Hereinafter, the gas movement pipe 20 which has such a structural characteristic is demonstrated concretely.

The gas moving tube 20 includes an inlet part 21 and a vortex forming part 22.

That is, the gas moving tube 20 is connected to the inlet 21 through which gas is introduced to one side, and the other side of the inlet 21 on the upper side in a tangential direction so that the gas is guided toward the inner circumferential surface and moved downward. And an installed vortex forming unit 22 (see FIGS. 2 and 3).

In this case, one side of the inlet 21 is installed to allow gas to be introduced from one side of the main body 1, and the other side of the inlet 21 is connected to the upper side of the vortex forming unit 22 by being connected to the inside of the main body 1. .

At this time, the other side of the inlet portion 21 connected to the upper side of the vortex forming unit 22 is connected to the vortex forming unit 22 in a tangential direction.

That is, the gas entering the vortex forming unit 22 from the inlet 21 enters the tangential direction of the vortex forming unit 22 and is guided to the upper inner circumferential surface so that the gas forms a helical flow (that is, vortex to vortex). And it is configured to move to the lower side of the vortex forming unit 22.

At this time, it is preferable that the inlet 21 is inclined at an angle from the upper side to the lower side and connected to the vortex forming unit 22 so that the gas flows more helically in the vortex forming unit 22.

That is, the inlet part 21 is connected to the vortex forming part 22 in a tangential direction and the gas entering the vortex forming part 22 from the inlet part 21 is guided by the inner circumferential surface of the vortex forming part 22. By allowing the spiral to flow, the cyclone principle can be applied by the gas flow pipe 20 itself.

The gas flowing from the inlet of the inlet 21 moves from the upper side of the vortex forming unit 22 to the lower side forming a spiral vortex along the inner circumferential surface and through the lower side of the vortex forming unit 22 to the reservoir 10. Discharged. At this time, the fine dust contained in the gas is spread out to the inside of the vortex forming unit 22 and the contact efficiency with the cleaning liquid stored in the reservoir 10 is greatly improved.

The gas pipe 20 may be further provided with an expansion pipe 23.

The expansion tube 23 is formed extending radially from the lower end of the vortex forming unit 22 (see Figs. 2 and 3).

That is, the gas flow pipe 20 has an inflow portion 21 in which one side enters gas from one side of the main body 1 and the other side is directed into the main body 1, and the other side of the inflow portion 21 is tangentially upward. Vortex forming portion 22 is connected to, and the lower end of the vortex forming portion 22 can be divided into a radial expansion pipe 23 is extended to extend.

In the vortex forming unit 22, a spiral-shaped vortex is formed and the gas flowing downward is widely spread through the expansion pipe 23 and comes into contact with the cleaning liquid of the storage tank 10, thereby cleaning the fine dust and the like contained in the gas. The contact efficiency of can be further improved.

That is, the helical vortex is formed in the vortex forming unit 22 and the gas flowing downward is reduced in the expansion pipe 23, and the washing liquid of the reservoir 10 is increased in a state in which the speed of the spiral vortex becomes smaller. Contact with Therefore, the contact efficiency of the fine dust and the like contained in the gas can be further improved.

In addition, since the pressure of the gas discharged into the cleaning liquid of the water storage tank 10 by the expansion pipe 23 is lowered, the load of the exhaust device for injecting the gas into the inlet 21 can be reduced.

That is, the speed and pressure of the gas passing through the vortex forming part 22 are reduced by the expansion pipe 23, thereby preventing a pressure hunting phenomenon at a portion in contact with the cleaning liquid.

By preventing the pressure hunting phenomenon as described above, not only the operation cost is reduced by reducing the load of the exhaust device, but also the effect of reducing the greenhouse gas and meeting the low carbon green growth is exerted. In addition, it is possible to operate the scrubber device with only a small load exhaust device, which makes it possible to miniaturize the scrubber device and to reduce the defective rate of the product to the scrubber device.

At this time, the lower end of the expansion pipe 23 is a saw blade portion 25 of the sawtooth shape is formed.

The area in which the saw blade portion 25 is in contact with the cleaning liquid of the gas reservoir 10 is increased, and the contact efficiency thereof may be further improved.

A plurality of through-holes 24 having a hole shape may be formed symmetrically in the expansion pipe 23.

The through-hole 24 is formed in the expansion pipe 23 to prevent the gas from shifting to one side within the expansion pipe 23, and the expansion hole 23 is formed in the expansion pipe 23 by the through-hole 24. It is possible to prevent the gas from drifting and to lower the contact efficiency with the cleaning liquid.

When the expansion pipe 23 is formed, the gas moving pipe 20 is installed so that the saw blade 25 of the expansion pipe 23 is immersed under the washing liquid surface 11 of the reservoir 10. However, when the through hole 24 is formed in the expansion pipe 23, all of the through holes 24 are installed to be submerged under the surface of the washing liquid of the reservoir 10.

The expansion pipe 23 of the gas moving pipe 20 may be formed as a double pipe.

4 and 5, the configuration in which the expansion pipe 23 of the gas flow pipe 20 is formed of a double pipe will be described.

In the case of the gas moving pipe 20 in which the expansion pipe 23 is formed of a double pipe, the gas spiral flow structure of the inlet part 21 and the vortex forming part 22 is as described above.

The basic structure of the expansion tube 23 is the same as described above, but the inner expansion tube 26 is further formed inside the expansion tube 23 in a form corresponding to the radial form of the expansion tube 23 ( 5).

That is, the inner peripheral surface of the expansion pipe 23 is further provided with an inner expansion pipe 26 which is radially expanded like the expansion pipe 23.

At this time, the inner expanding portion 26 is also formed in a radial shape having a diameter larger than the diameter of the vortex forming portion 22.

At this time, the inner expansion portion 26 is formed to have a shorter length than the expansion portion 23, so that the inner expansion portion 26 is formed inside the expansion portion 23.

The lower end portion of the inner expansion portion 26 is formed with a sawtooth inner blade portion 27 similar to the saw blade portion 25 formed at the lower portion of the expansion pipe 23.

However, when the expansion pipe 23 is formed of a double pipe, it is preferable that the above-described through hole 24 is not formed in the inner expansion pipe 26.

That is, all of the surfaces of the inner expansion portion 26 are hermetically sealed, so that holes such as the through hole 24 are not formed.

That is, it is preferable that the through hole 24 is formed only in the expansion pipe 23, and the gas moving pipe 20 is partially or entirely part of the inner saw blade 27 soaked on the surface of the cleaning liquid of the water storage tank 10. In this case, the through hole 24 of the expansion pipe 23 is preferably installed so as to be immersed in the surface of the cleaning solution of the reservoir (10) (see Fig. 4).

Due to the double pipe structure by the inner expansion part 26 of the expansion pipe 23 described above, the helical vortex is formed in the vortex forming part 22 and the gas moved downward rotates along the inner expansion pipe 26. As the radius increases, it decelerates and passes through the inner saw blade portion 27 to come into contact with the cleaning liquid.

In addition, the gas that has contacted the cleaning liquid through the inner blade portion 27 passes through the inner space between the expansion portion 23 and the inner expansion portion 26 and passes through the saw blade portion 25 of the expansion portion 23. It is discharged into the inside.

At this time, the description of the through-hole 24 formed in the expansion tube 23 is as described above.

The gas contacting the cleaning liquid past the inner saw blade portion 27 of the inner expansion pipe part 26 undergoes a first purification process in which fine dust and the like are removed, and the gas particles are combined with the cleaning liquid, become heavy and at the same time have a large volume. You lose.

In this case, when a part of the inner saw blade portion 27 is installed to be submerged on the surface of the cleaning liquid of the reservoir 10, the pressure generated by the inner expansion portion 26 is minimized to the gas moving tube 20 It is possible to reduce the load on the exhaust device that supplies the gas.

Subsequently, the gas from which the fine dust and the like is first removed is passed through the saw blade portion 25 of the expansion part 23 into the cleaning liquid in a bulky and heavy state to undergo a second purification process.

At this time, in the secondary purification process, the gas particles pass through the cleaning solution in a bulky and heavy state, whereby fine dust and the like that have not been treated in the primary purification process can be more efficiently purified by the cleaning solution.

The fine scrubber apparatus according to the present invention may further include a cleaning liquid inlet unit 30 inside the vortex forming unit 23 of the gas moving tube 20.

At this time, the cleaning liquid inlet 30 is preferably installed to be close to one side of the upper inner peripheral surface of the vortex forming unit 22.

This is because the gas entering the vortex forming unit 22 from the inlet 21 forms a spiral vortex along the inner circumferential surface of the vortex forming unit 22, so that the cleaning liquid is injected onto the inner circumferential surface of the vortex forming unit 22. For sake.

The cleaning liquid injected by the cleaning liquid inlet unit 30 forms a naked thread type vortex and breaks the droplet of the moved gas small so that the contact area with the cleaning liquid is increased, thereby improving the cleaning efficiency. .

In addition, the cleaning liquid inlet unit 30 sprays the cleaning liquid to the gas forming the spiral vortex in the vortex forming unit 22 to form a water film on the inner wall of the gas moving tube 20, thereby preventing clogging and destroying the cleaning liquid. As a result, the contact area is maximized so that cleaning efficiency or dust collection rate can be maximized.

The nozzle may be used as the cleaning liquid inlet 30.

In addition, the fine scrubber device of the present invention preferably further comprises a packed bed 40 for treating the harmful gas rising to the upper portion of the body (1).

The air flowing into the gas flow pipe 20 through the inlet 21 includes dust, harmful dust, droplets, as well as harmful gases. It does not settle in the washing | cleaning liquid of (10), but rises to the upper part of the main body 1.

Therefore, the rising gas gas is absorbed by the packing included in the filling layer 40 while passing through the filling layer 40, so that harmful gas may be effectively removed even when gas gas is included.

In this case, the filling layer 40 is preferably composed of a stretchable filter, in addition to forming a single layer, the stretchable filter may be composed of a double, triple or more layers.

In addition, the fine scrubber device according to the present invention preferably further comprises a spray nozzle 50, the gas-liquid separator 60 and the discharge port (2).

That is, an injection nozzle 50 installed inside the main body 1 above the filling layer 40 and spraying a cleaning liquid to the filling layer 40 and inside the main body 1 above the injection nozzle 50. It further comprises a gas-liquid separator 60 is installed in the upper portion and the discharge port (2) formed on the upper portion of the main body 1 is discharged.

The spray nozzle 50 is installed on the filling layer 40 inside the main body 1 to spray the washing water to the filling layer 40. That is, the spray nozzle 50 sprays the washing water toward the filling layer 40 in the lower direction of the main body 1 to prevent the rise of harmful gas and the like and to be easily absorbed by the filling layer 40.

The gas-liquid separator 60 is installed on the upper part of the injection nozzle 50 inside the main body 1, and liquids such as water droplets in the washed gas gas rising after the harmful gas is absorbed by the packed bed 40. Remove it.

At this time, the clean gas from which liquid such as water droplets is removed is discharged to the outside of the main body 1 through the discharge port 2 formed in the upper part of the main body 1.

The fine scrubber apparatus according to the present invention further includes a pump 70 for supplying the cleaning liquid to the cleaning liquid inlet 30 and the injection nozzle 50.

At this time, it is preferable that the pump 70 is installed outside the main body 1 to supply the cleaning liquid to the cleaning liquid inlet 30 and the injection nozzle 50.

An inclined surface inclined from one side to the other side may be formed at a lower end of the reservoir 10.

The inclined surface is introduced into the cleaning liquid of the water storage tank 10 so that impurities precipitated down may be moved to one side along the inclined surface to facilitate management of the cleaning liquid of the water storage tank 10.

6 is a graph showing a change in pressure hunting according to the velocity of the gas in contact with the cleaning liquid when the expansion pipe 23 has a single pipe structure.

As shown in FIG. 6, it can be seen that as the gas velocity increases, the pressure hunting ΔP, that is, the pressure loss increases.

Therefore, the pressure hunting is prevented due to the reduction of the gas velocity by the expansion pipe 23, and the scrubber device can be operated with only a small load.

In the graph of FIG. 6, the x axis represents the velocity of the gas in contact with the cleaning liquid and the y axis represents the hunting range ΔP.

7 is a graph showing the cleaning efficiency, that is, the dust collection rate, according to the speed of the gas contacting the cleaning liquid when the expansion pipe 23 has a single pipe structure. In this case, Figure 7 is a graph of the dust collection rate experiment for the SiO2 dust of the fine dust contained in the gas.

As shown in FIG. 7, it can be seen that as the velocity of the gas contacting the cleaning liquid decreases, the dust collection rate increases.

That is, the expansion pipe 23 can maximize the gas cleaning effect.

In the graph of FIG. 7, the x-axis is the velocity of the gas in contact with the cleaning liquid, and the unit is m / sec, and the y-axis is the dust collection rate (η) according to the gas velocity with respect to SiO 2 dust included in the gas.

8 is a graph showing pressure loss ΔP for each flow rate of gas in contact with the cleaning liquid.

As shown in FIG. 8, it can be seen that the pressure loss increases as the gas velocity increases.

9 is a graph showing the dust collection rate according to the velocity of the gas in contact with the cleaning liquid when the expansion pipe 23 has a double pipe structure.

As shown in FIG. 9, when the expansion tube 23 is formed of a double tube, it can be seen that the rate of dust collection for each speed in FIG. 7 is further improved.

That is, by forming the expansion pipe 23 in a double pipe it is possible to maximize the cleaning efficiency.

Therefore, even if the expansion pipe 23 is formed in a double pipe structure and the pressure hunting is slightly increased, it is still possible to achieve a high cleaning effect due to the improvement of the dust collection rate.

In this case, the unit of the x-axis and y-axis in the graph of FIG. 9 is the same as FIG.
