Description

Deodorization apparatus of foul smell gas with improved water cleaning function

In the present invention, after the deodorization operation with washing water is preceded to deodorize the odor substances contained in the gas to be treated, the degree of deodorization of the gas to be treated can meet the standard value even with minimal chemical use as a post-treatment process. It relates to an odor gas deodorizing device with an improved water cleaning function that can be discharged.

In general, in places such as sewage treatment plants, excreta treatment plants, food treatment facilities, livestock facilities, etc., various organic or inorganic gases are generated and a complex odor is produced. With a single chemical cleaning solution such as a slow oxidizing agent, effective treatment of odor gas is difficult.

As a method of removing odor gas of complex nature based on these characteristics, a plurality of nozzles are installed in a deodorization tower, and the odor is removed by contacting water with a gas containing odor introduced into the deodorization tower from this (washing method). In addition, there is a method of arranging an adsorbent layer such as activated carbon, silica gel, and zelite in the deodorization tower to adsorb odor substances (adsorption method), or a specific microbial layer instead of the adsorbent so that the microorganisms can remove odor-generating substances There is a method to decompose it (microbe contact method), etc.

As such, the malodorous gas composed of a complex gas is usually purified by a neutralization reaction with an 'acid and alkali' chemical solution, and such a conventional deodorizing tower has a slow reaction rate and low efficiency, but an oxidizing agent that reacts complexly (sodium hypochlorite, etc.) It consists of a single deodorizing tower using In order to improve these problems in recent years, domestic registration patent No. 10-0820845 has been disclosed as a prior art because it has a problem of requiring excessive installation space and installation cost due to its enlargement.

In the case of the above-mentioned prior art, the two-liquid simultaneous washing deodorization tower has an acid and alkali washing tower as an integrated deodorization tower, so that each washing liquid circulates separately to clean the complex gas, thereby reducing the size of the device, and on the other hand, acid or alkali washing tower. Even when cleaning alone, the jet nozzle and the pack bed two-stage cleaning are performed to secure excellent cleaning power, and the simultaneous neutralization reaction of acid and alkali has the effect of improving the deodorizing power.

The two-liquid simultaneous cleaning and deodorization tower uses a jet nozzle when cleaning the complex gas, wherein the jet nozzle corresponds to a gas distribution room having a plurality of supply pipes, and the supply pipe of the gas distribution room, but when combined, the outer end and a set interval It is formed so as to be covered and formed into a supply hole, and a spray cap is formed so that the odor gas is injected into the liquid through the supply hole onto the bubbles, and the jet nozzles are arranged in a plurality of uniformly distributed inside the body.

On the other hand, in the prior art, it is obvious that a large amount of chemicals must be used according to the concentration of the complex gas to increase the deodorization efficiency of the complex gas containing the malodorous material, and for this reason, the cost for deodorization of the complex gas is increased. is accompanied by the problems of
