Chemical liquid cleaning deodorizer with wet dust removal function in incoming odor gas}

The present invention relates to a chemical liquid cleaning deodorizer having a function to remove wet dust in an incoming odor gas, and more specifically, by installing a wet pre-filter between the outlet of the odor gas supply fan and the gas distribution chamber of the chemical liquid cleaning deodorizer. Filter the dust (for example, various foreign substances and dusts, hereinafter referred to as "dust") contained in the odor gas flowing into the gas distribution chamber of the body at a predetermined pressure by the odor gas supply fan through a wet pre-filter Inside, however, the dust applied to the demister filter is automatically cleaned by spraying water on the front of the demister filter provided inside, and then automatically collected through the drain pipe into the dust and washing water collection container. It can greatly improve the collection efficiency of the filter, and at the same time, increase the exchange or cleaning time of the filter itself, so that It relates to a chemical liquid cleaning type deodorizer having a wet dust removal function in the inlet odor gas invented to significantly increase the deodorizing effect and efficiency of the odor gas.

In general, various organic or inorganic gases are generated in places such as sewage treatment plants, manure treatment plants, food processing facilities, and animal husbandry facilities to generate complex odors. There is a characteristic that the processing becomes difficult.

As a method of removing the organic or inorganic odor gas based on these characteristics, a number of nozzles are installed in the deodorization tower, and water is sprayed on the gas containing the odor introduced into the deodorization tower to remove the odor (water washing method) In addition to this, in addition, a method in which an adsorbent layer such as activated carbon, silica gel, and zeolite is disposed in a deodorization column to adsorb malodorous substances (active carbon adsorption method), or a specific microbial layer is disposed in place of the adsorbent to cause the microorganism to stink There is a method to decompose the generated substances (microbial contact method).

As described above, the odor gas composed of a composite gas is usually cleaned by causing a neutralization reaction by 'acid and alkali', and such a normal deodorization tower is a separate deodorization tower, that is, an acid and alkali washing tower which are respectively configured in series or in parallel. As it is made of, it is not quick or has a limited problem in the hassle of construction production and the deodorizing power of the composite gas, and the installation space has been limited due to the enlargement of the device.

Accordingly, the present applicant has developed a two-liquid simultaneous cleaning deodorization tower capable of solving the above-mentioned problems and proposed it as Korean Patent Registration No. 10-0820845.

The two-liquid simultaneous cleaning and deodorizing tower proposed in Korean Patent Registration No. 10-0820845 has a mist collecting part and an exhaust port formed above the hollow body, and a gas distribution chamber at the bottom and a odor gas supply fan on the outside side. A main body on which a malodor gas inlet pipe is formed so that the introduced malodor gas is introduced; A first tank formed on the bottom surface of the main body to receive the acid cleaning liquid, a first circulation pump formed on one side of the first tank and configured to transfer the received acid cleaning liquid to the upper side of the main body, and the first circulation pump It is formed on the lower part of the first injection tube and the first injection tube having a plurality of supply holes so as to spray the acid cleaning solution transferred by the body toward the lower portion, and secures a maximum contact area between the odor gas and the cleaning solution. A pack bed formed to collect odor gas, a collection dich that is sprayed by the first injection pipe to pass through the pack bed, and is formed to collect the acid cleaning solution falling to the bottom of the pack bed, and is formed on one side of the collection dich. An acid cleaning unit provided with a first collection pipe to transfer the collected acid cleaning solution to the first tank; The second tank is formed on the bottom surface of the main body and is adjacent to the first tank and is formed to receive the alkaline cleaning solution. The second tank is formed on one side of the second tank, and is formed to transfer the received alkaline cleaning solution to the lower side of the collecting dich of the acid cleaning part. In the second circulation pump, the second supply pipe having a plurality of supply holes to supply the alkaline cleaning liquid transferred by the second circulation pump into the main body, and the alkaline cleaning liquid supplied by the second supply pipe to maintain a constant water level While jetting the odor gas to clean the odor gas, the jet nozzle is formed to remove dust contained in the odor gas, and the second nozzle is adjusted to the second tank while adjusting the water level of the circulating alkali cleaning solution formed on one side of the jet nozzle. It is composed of; an alkali cleaning unit is provided is provided with a second collecting pipe for circulation.

At this time, the jet nozzle has a gas distribution chamber having a plurality of supply pipes; It has a shape consisting of; a spray cap that corresponds to the supply pipe of the gas distribution chamber but is formed to be covered with a set distance from the outer end when combined to form a supply hole and to spray odor gas into the air through the supply hole.

A two-liquid simultaneous cleaning and deodorizing tower having such a configuration is equipped with an acid and alkali cleaning tower at the same time, and each cleaning liquid circulates separately to promote cleaning, thereby miniaturizing the device, and for odors that are complex gases. In addition to being able to secure quick and excellent cleaning power, it was possible to obtain an effect of significantly improving the deodorizing power by simultaneously neutralizing the acid and alkali.

On the other hand, in most conventional chemical cleaning detergent deodorization towers (or deodorizers, deodorizers, etc.), odor gas generated in various industrial facilities or livestock facilities is collected and directly introduced into the gas distribution chamber provided in the body through the odor gas supply fan. It is composed.

However, in this configuration, the jet that removes the solids contained in the malodor gas in the process of passing through the alkali scrubber and the pickling government as the malodor gas flowing into the gas distribution chamber flows into the gas distribution chamber. The pack bed collecting the nozzle and the odor gas and the collecting dich that collects the acid cleaning solution in the lower part of the pack bed are easily blocked by a lot of dust, so that the amount of odor gas passing through is reduced, and the negative pressure in the main body is largely applied to the odor gas. The deodorizing effect and efficiency of the product is greatly reduced, and the operation rate of the chemical cleaning deodorizing tower is greatly reduced due to frequent inspection and maintenance due to the removal of dust on the entire body. There is a problem.

Accordingly, in recent years, in some chemical liquid cleaning type deodorization towers, a generally known dry filter (for example, a non-woven fabric filter) is installed between the outlet of the odor gas supply fan and the inlet of the gas distribution chamber to provide a predetermined pressure by the odor gas supply fan. In some cases, the dust contained in the odor gas flowing into the gas distribution chamber of the main body is filtered through a filter.

However, the dry filter as described above simply performs a function of filtering out dust contained in the odor gas flowing into the gas distribution chamber of the main body at a predetermined pressure by the odor gas supply fan, so that the deodorization operation of the chemical liquid cleaning deodorization tower is performed. In a short period of time, the dry filter becomes clogged by dust, so the deodorization operation of the chemical cleaning detergent deodorizing tower must be stopped frequently and the filter must be replaced or cleaned frequently. There is such a problem that it takes a lot.
