Description

Technical Field

[0001] The utility model relates to the technical field of waste gas deodorization, and more specifically, to a waste gas treatment device generated in sewage treatment. Background Art

[0002] Deodorization equipment, that is, air purification equipment used to remove odors and remove odors, is widely used in factories, workshops, sewage stations, garbage plants, etc. The deodorization equipment has a simple structure and has the characteristics of low energy consumption, high purification efficiency and wide application range. The waste gas generated in sewage treatment is mostly treated by biological deodorization. Biological deodorization mainly uses microbial deodorization. Through the physiological metabolism of microorganisms, the odorous substances are transformed so that the target pollutants are effectively decomposed and removed to achieve the purpose of odor control.

[0003] The existing patent number CN117563401A discloses a waste gas deodorization device for a sewage station. During the process of circulating filtration and deodorization, the waste gas is driven by the air pressure of the waste gas to circulate inside the purification box, and different areas are formed by multiple partitions, which can increase the residence time of the waste gas in the purification box. Through different process treatments, the effect of waste gas purification and deodorization can be effectively improved. However, the distance between the air intake pipe and the gap under the first partition is relatively close. After the waste gas enters from the air intake pipe, it will quickly flow into the other side of the first partition, resulting in too short spraying time and insufficient gas-liquid contact. In addition, the gas after spraying contains more moisture and impurities that have not been filtered out, which affects subsequent treatment.

[0004] In view of this, research and improvement are carried out on the existing problems, and a waste gas treatment device generated in sewage treatment is provided, aiming to achieve the purpose of solving the problem and improving the practical value through this technology.
