In FIG. 3, the polling chamber 20 has mouths and outlets 22 and 24 formed on both sides of the upper part, and odor gas and washing water discharged through the outlet 14 of the venturi tube 10 inside the inlet 22 side. The polling layer 25 is formed to widen the contact area of the, and the inlet and the outlet 22 of the polling chamber 20 are able to collect dust contained in the odor gas that has passed through the polling layer 25 again. In the interior space, a nozzle 26 for spraying washing water is provided. In addition, a cleaning water tank 27 and a pump are provided at one side of the polyl chamber 20 to continuously supply cleaning water to the nozzle 26.

At this time, the polling layer 25 is provided in a state in which the washing water sprayed and discharged from the Venturi tube 10 is adsorbed or the cleaning water sprayed through a separate nozzle is adsorbed on the surface. 22) The contact time of the odor gas flowing through the polluted layer 25 with the washing water is extended and the contact area is widened, thereby improving the efficiency of removing dust contained in the odor gas.

As the surface particles of the deodorant liquid are finely crushed by the wind pressure of the gas when sprayed with, the dust and odor components contained in the odor gas are dissolved and adsorbed in the deodorant liquid.

At this time, the underwater aeration or surface aeration method by the radiation aeration tank 30 controls the height of the detonation liquid 35 based on the deodorant liquid level or the deodorant liquid level based on the height of the detonation liquid 35 By doing so, the underwater aeration method and the surface aeration method can be easily selected and switched.

The aeration pipe 35 of the radiation aeration tank 30 is arranged to be radially arranged based on the center of the radiation aeration tank as shown in FIG. 4 (b), and the injection direction is set so that the odor gas is intensively injected into the center. The odor gas injected through the aeration pipe 35 is in contact with the deodorant liquid stored in the radiation aeration tank 30 by means of underwater aeration or surface aeration.

Therefore, the odor gas injected through the aeration pipe 35 collides with the deodorant and deodorizes the primary aeration, and then the odor gas deodorized by primary impact in a plurality of locations is concentrated and sprayed in the center of the circle. As they are more finely separated, the secondary aeration is deodorized by collision contact with the odor gas, and the odor gas deodorized by the secondary aeration is discharged through the outlet 34 formed on the top of the radiation aeration tank 30.

As described above, since the odor gas sprayed from a plurality of places through the aeration pipe 35 is first and second and collides with the deodorant liquid, the efficiency of removing dust and odor components is improved.

On the other hand, in the radiation aeration tank 30 by the surface aeration method, a guide plate 36 for limiting the aeration depth of the deodorizing gas is installed below the surface of the deodorization liquid at the bottom of the radiation aeration tank 30 corresponding to the aeration pipe 35. , At the end of the guide plate 36, the inclined plate 38 bent upward is provided to be exposed over the surface of the deodorant liquid. As shown in FIG. 5, after the odor gas sprayed in the transverse direction from a plurality of places through the explosive pipe 35 collides with the deodorant liquid, the direction of movement is switched upward by the inclined plate 38, thereby improving contact efficiency with the deodorant liquid. Improved, and the odor gas that has undergone a collision contact process with the deodorant liquid has the wind direction switched upward by the inclined plate 38 so that the discharge through the outlet 34 formed on the top of the radiation aeration tank 30 can be quickly and without interference. There is an advantage made.

As shown in enlarged view of the explosive pipe 35 in FIG. 4 (a) in order to simultaneously effect the underwater aeration and the surface aeration, the outlet of the explosive pipe 35 is arranged to be completely submerged under the surface of the deodorant, and the width In the engine 35, a plurality of through holes 35a may be formed at a height close to the surface of the deodorant liquid.

In this case, a significant number of the odor gas flowing through the aeration pipe 35 is forcedly contacted while flowing into the deodorant liquid, and some gas is discharged through the through hole 35a and collides with the surface of the deodorant liquid to finely deodorize particle As it is pulverized, the deodorizing effect due to gas-liquid contact is further enhanced.

In addition, the deodorant liquid of the radiation aeration tank 30 is made of any one of a mixture of water, sodium hypochlorite, or a mixture thereof, and the contamination concentration of the odor gas introduced into the radiation aeration tank 30 is detected by the control unit to the control unit. When the contamination value is higher than the set value, a sodium hypochlorite solution is provided. That is, the control unit detects the pollutant concentration value of the odor gas input into the radiation aeration tank 30 using a sensor, and when the pollutant concentration value is equal to or less than the value set in the control unit, operates using water as a deodorant, and operates When the value is higher than the value set in the control unit, the sodium hypochlorite solution is converted into a deodorizing liquid and operated.

Thus, depending on the odor gas pollution concentration, that is, when the degree of contamination is low, the surface aeration type radiation aeration tank 30 is formed, and when the degree of contamination is high, the radiation aeration tank 30 has both underwater aeration or underwater aeration and surface aeration. By allowing to be applied flexibly, it is possible to control the amount of deodorant solution containing sodium hypochlorite which is harmful to the environment and expensive, thereby significantly reducing maintenance costs associated with operating the deodorant system.

The contact chamber 40 according to the present invention includes an ozone (O3) bubble contact tank 42, a titanium dioxide (TiO2) contact tank 44, and a water washing contact tank 46 connected to the radiating aeration tank 30 outlet 34. ).

The ozone bubble contact tank 42 of the present invention is characterized by using ozone dissolved water in which ozone generated using an ozone generator is dissolved in water in a microbubble state instead of using ozone gas.

When one side of the ozone bubble contact tank 42 is provided with a tank in which ozone dissolved water in which ozone is dissolved in water in a microbubble state is stored, and supplied to the inner upper portion of the ozone bubble contact tank 42 by a pump, when the nozzle is sprayed downward As the microparticles containing ozone burst, the deodorization effect is excellent because the deodorization is achieved by contact with the odor gas passing through the ozone bubble contact tank 42. Moreover, since ozone dissolved water is used without using ozone gas, it is possible to eliminate corrosion or environmental pollution problems caused by ozone gas remaining in the discharge portion of existing devices.

In the titanium dioxide (TiO2) contact tank 44, a plurality of quartz pipes are installed on both sides in parallel with the gas discharge direction, and a UV lamp is installed inside the quartz pipe. In addition, a tank in which a titanium dioxide solution is stored is provided on one side of a titanium dioxide (TiO2) contact tank 44, and is supplied to the inner upper portion of the titanium dioxide contact tank 44 by a pump to be sprayed downward through a nozzle. ) It is provided so that UV is irradiated by the UV lamp 44a installed inside, and the OH radical generated in this process reacts with the odor to reduce the odor through oxidation and reduction reaction of the photocatalyst.

The water washing contact tank 46 is installed to finally clean the residual salt or residual ozone that may occur when treating a high concentration of odor gas by contact with the washing water, and is selectively activated by the control unit.

In addition, the ozone (03) bubble contact tank (42), titanium dioxide (TiO2) contact tank (44), and the deodorizing liquid sprayed through the nozzle from the water washing contact tank (46) have a structure that is collected and circulated from the bottom.

The malodorous odor gas deodorization system provided as described above is firstly deodorized while simultaneously removing most of the high temperature odor gas dust passing through the Venturi tube 10 and the poly chamfer 20, and the aeration tank 30 ) The second deodorization is performed using the deodorant solution, and the three-stage deodorization process is performed through the last morning bubble contact tank 42 and the titanium dioxide contact tank 44.
