Description

Inlet Gas Equalization Deodorizer {Deodorizer equipped with gas flow equalizing device}

The present invention relates to an inflow gas equalization deodorizer, and more particularly, so that the flow rate of the odor gas moving upward can be induced to be uniformly introduced without being biased, and the falling cleaning liquid can also be smoothly transferred to the lower part. It relates to an inlet gas equalization deodorizer to improve the performance of the deodorizer by inducing it.

In general, when odor gas generated in industrial sites such as factories or livestock houses is released into the atmosphere as it is, it not only causes air pollution, but also greatly harms the health of residents, and furthermore, causes disputes such as civil complaints.

A deodorizer is used for the treatment of such a malodorous gas, and such a deodorizer is usually provided with a filling filter material for deodorizing treatment while passing the malodorous gas, and by spraying a cleaning liquid containing a chemical on the filling filter material, the reaction with the malodorous gas deodorization can be achieved by

On the other hand, for effective deodorization of odor gas, a multi-stage deodorizer has been developed and used to remove odor by spraying a cleaning liquid to the odor gas multiple times. As a related prior art, Korean Patent No. 10-1513682 A "cleaning multi-stage deodorizing device" has been proposed, which is a deodorizing device that removes odors contained in exhaust gas generated in a sewage treatment plant or a food waste treatment plant, wherein the deodorizing device includes an exhaust gas flowing into one side. a housing having an inlet and having a hollow interior; a primary cleaning unit for cleaning the exhaust gas by filling the inner bottom of the housing with water; a primary filter unit positioned above the primary cleaning unit and uniformly dispersing the exhaust gas; a secondary cleaning unit positioned above the primary filter unit and spraying an acidic cleaning solution to clean the exhaust gas; a secondary filter unit positioned above the secondary cleaning unit and uniformly dispersing the exhaust gas again; a tertiary cleaning unit positioned above the secondary filter unit and spraying an alkaline cleaning solution to clean the exhaust gas; a tertiary filter unit located above the tertiary washing unit and treating the mist and chemical odor of unreacted acidic and alkaline washing liquid; It is located on the upper part of the tertiary filter part and consists of a quaternary filter part having a sterilization function while removing harmful substances.

In addition to the prior art, the existing cleaning deodorizer is designed in such a way that the odor gas rises from the lower side to the upper side, and the washing liquid falls from the upper side to the lower side. A drift is formed, and due to the drift formed in this way, the internal reaction space cannot be used sufficiently, so there is a problem in that the removal efficiency of odor substances is remarkably reduced.

In order to solve this problem, there is a method of installing a perforated plate as a representative method for equalizing the flow rate. However, if the hole of the perforated plate is large and the opening ratio is large, the pressure loss is reduced, while the flow equalization effect is lowered. On the other hand, if the hole is made small and the aperture ratio is reduced, the flow rate equalization effect is improved, but there is a problem in that the operating cost is increased due to an increase in pressure loss, as well as in the case where only odor gas is introduced. On the other hand, when there is a supply of washing water, interference and collision between the washing water falling downward and the rising odor gas occur, and some sections function as washing water passages and some are used as odor gas transfer passages, There was a problem in that the decrease in treatment efficiency due to the occurrence of drift became serious.

In order to solve the problems of the prior art as described above, in the present invention, in the deodorizer in which the malodorous gas rises from the lower side to the upper side and the cleaning liquid falls from the upper side to the lower side, the flow rate of the malodorous gas moving upward is not biased. The purpose is to improve the performance of the deodorizer by inducing it to flow evenly, and by inducing the falling cleaning liquid to be smoothly transferred to the lower part.
