Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention.

2 is a plan view of a wet cyclone deodorization apparatus. FIG. 3 is a plan sectional view of a deodorization tower in a wet cyclone deodorization apparatus, and FIG. 3 is a plan view of a wet cyclone deodorization apparatus according to the present invention. The present invention relates to a wet cyclone deodorizing apparatus (1) for collecting seashells separately and purifying polluted gases when the polluted gas containing dusts generated in various industrial sites is introduced through the external blower Referring to the drawings, the cyclone collector 10 and the deodorizing tower 20 can be divided into two.

First, the cyclone collector 10 is contained in a gas before cleaning the contaminated gas to separate and collect dust and dirt that have flowed into the deodorizing apparatus 1. The cyclone collector 10 is connected to an upper portion of the body 11 in the form of an inverted truncated cone, And a discharge port 13 is formed at a lower portion of the main body to connect the discharge pipe to the discharge port 13. The center portion of the main body 11 has an inner And a pipe (14).

Therefore, the airflow containing the tears coming into the inlet 12 through the external blower 100 goes down while turning inside the cyclone, and the large and heavy particles settle down along the inner wall of the body 11 by the centrifugal force, The gas is elevated by the wind pressure continuously pushed by the blower and moved to the upper portion of the inner tube 14. [

The contaminated gas passing through the cyclone collector 10 flows into the deodorization tower 20 which is connected to the upper side of the internal pipe 14 in a full-fledged manner. After passing through a multi-stage gas-liquid contact process, the polluted gas is purified and discharged as a clean gas. The chemical liquid tank 40 for collecting and storing the chemical liquid L and the pump 41 for transferring the chemical liquid L in the tank into the deodorization tower 20 are installed outside the deodorization tower 20 as shown in the figure, Or may be integrally formed with the deodorizing tower.

The bottom of the deodorization tower 20 is provided with a water collecting tank 21 in which the chemical liquid L to be dumped is collected and the gas flowing into the bottom of the water collecting tank 21 through the inner pipe 14 of the collecting machine is introduced into the deodorization tower 20, A plurality of vents 24 are formed.

A bottom surface of the water collecting tank 21 is connected to a chemical liquid tank 40 for collecting the chemical liquid L at the center of the water collecting tank 21 so that the chemical liquid L flows smoothly It is preferable that it is formed so as to be sloped toward the drain pipe 22 so as to be discharged.

A water level controller 23 is provided in the middle of the drain pipe 22 connecting the water collecting tank 21 and the chemical liquid tank 40 to control the water level of the chemical liquid collected in the water collecting tank. This is because when the chemical solution in the water collecting tank 21 is excessive, the chemical solution flows back to the cyclone collector 10 through the vent 24, and in the opposite case, the deodorization efficiency is lowered. .

As shown in the drawing, the level controller 23 may be configured to control the size of the flow path in the level controller 23 by raising and lowering the disk by a handle operation. Alternatively, a level switch may be separately provided in the water collector 21, It may be configured to be controlled automatically in linkage.

As shown in an enlarged perspective view of FIG. 4, a uniformly arranged induction pipe 25 is formed above the vent 24, and the contaminated gas diffused through the vent 24 is introduced into the induction pipe 25 Thereby limiting the movement path of the gas so that the gas can be moved to the upper portion only.

At the same time, when a nozzle for spraying the chemical liquid L transferred to the lower chemical liquid supply pipe 27 by the pump 41 as fine particles is provided in the lower central portion of the induction pipe 25, the contaminated gas passing through the flow path defined by the induction pipe By concentrating the spray of the chemical liquid (L), the adhesion between the contaminated gas and the chemical liquid is enhanced, and a more excellent deodorizing effect can be provided.

The shape of the induction pipe 25 is preferably formed in the form of a fallopian tube having a lower orifice in consideration of the spraying range of the spreading fluid through the nozzle. In order to make the fine particles contact with the contaminated gas more efficiently, A plurality of protruding fins 25a may be formed in the flow path as in the other embodiments of the induction pipe 25. [

This causes the chemical liquid L sprayed from the lower side of the induction pipe to flow downward through the projecting pin 25a and the gas rising along the induction pipe 25 is limited in speed by the projecting pin 25a, The contact time and the contact area with each other can be further increased.

The gas introduced into the induction pipe 25 is aerated with the chemical liquid L filled in the aeration tank 29 through which an upper portion of the induction pipe is penetrated to filter light dust and fine dust that are not filtered by the cyclone trap 10. To this end, a hemispherical oil tool 26 for introducing gas into the aeration tank 29 is connected to the upper end of the induction pipe 25 to infiltrate the gas into the chemical liquid.

The liquid level of the chemical liquid L contained in the aeration tank 29 is lower than that of the upper end of the induction pipe and higher than the lower end of the oil guide 26. In order to maintain the water level therebetween, The chemical solution which is lower than the upper end of the induction pipe 25 at a position higher than the lower end of the oil tool 26 and overflows to the upper end of the water discharge pipe 30 is guided to the lower water collection tank 21, (30) to the collecting tank.

As shown in the plan sectional view of FIG. 3, upper chemical liquid supply pipes are arranged on the upper portion of the aeration tank 29 so as to uniformly spray the chemical liquid L without a dead zone over the entire cross-sectional area of the deodorization tower 20, Liquid contact with the malodorous gas that is aroused by the upper nozzle 32. The upper layer of the upper chemical liquid supply pipe 31 is provided with a polling layer (not shown) for absorbing residual odor components of the gas before being discharged to the exhaust port 34 33).

FIG. 6 is a front sectional view showing another preferred embodiment of the wet cyclone deodorization apparatus, and FIG. 7 is a plan view of FIG. 6, in which a heterogeneous chemical solution which reacts efficiently when the components of the source causing the odor are complex As shown in the figure, the water collection tank 21 having the vent 24 formed on the polling layer 33, the lower chemical liquid supply pipe 27 having the lower nozzle 28, the induction pipe 25, the aeration tank 29 A deodorizing tower 20 composed of an upper chemical liquid supply pipe 31 provided with an upper nozzle 32 and a polling layer 33 may be formed in two stages.

At this time, the second deodorization tower formed on the upper part further includes a second pump 41 'for supplying a second chemical liquid L' of different kind and a second chemical liquid tank 40 'for collecting and storing the chemical liquid, 2 The chemical liquid (L ') circulates smoothly.

Hereinafter, the operation of the wet cyclone deodorizing apparatus 1 provided in the present invention will be described.

When the contaminated gas containing the forced dust and dust is introduced by the blower 100, the large and heavy dusts are first collected down through the cyclone collector 10 and the polluted gas together with the fine dust is collected in the inner tube 14, And flows into the deodorization tower 20 through the vent 24 in a uniform manner.

To remove the pre-deodorization grease first is to minimize the possibility that dust adheres to various constituent members in the deodorization tower 20 to degrade its functionality, contaminate the chemical solution L and cause a trouble.

The introduced gas is raised and lowered via the induction pipe 25. At this time, the chemical liquid L is concentratedly sprayed through the lower nozzle 28 from the lower side of the induction pipe to increase the gas-liquid contact density to increase the deodorization efficiency, Liquid contact with the filled chemical liquid (L) is performed again, and the residual fine dust is immersed in the chemical liquid (L) and separated from the gas.

The gas passing through the aeration tank 29 finally undergoes a gas-liquid contact reaction with the chemical liquid sprayed from the upper nozzle 32 and finally passes through the poling layer 33 to discharge only the gas cleaned very cleanly to the exhaust port 34.

As described above, in the deodorizing device 1 of the present invention, the drip is removed through the cyclone collector 10 and the aeration tank 29, and the contaminated gas is passed through the deodorization tower 20 through the three- And thus the durability and deodorizing effect of the deodorizing device 1 are increased.
