Photo-oxidative combined double-fluid double-spray washing deodorization reactor and application method thereof

Abstract

The invention provides a photo-oxidative combined double-fluid double-spray washing deodorization reactor and an application method thereof. Through the mode of arranging a photo-oxidative catalyst preprocessor, a spray device and two different filler sections, a 45-degree air guide bend is arranged at the side of the first filler section, and the photo-oxidative catalyst preprocessor is arranged in the 45-degree air guide bend; the usage amount and processing difficulty of a chemical deodorizing agent are reduced, operation cost is saved, the design retention time of a chemical scrubbing tower is shortened, the problem of ozone secondary pollution is solved thoroughly, a tail gas processing device does not need to be arranged, and the safeguard rate of the processing effect is increased.

Description

technical field [0001] The invention relates to a deodorizing reactor and an application method thereof, more specifically, a photo-oxygen combined double-liquid double-spray washing deodorization reactor and an application method thereof. Background technique [0002] Municipal sewage, sludge treatment and garbage disposal facilities are important sources of malodorous gases. In municipal sewage treatment, different treatment facilities and processes will produce various odorous gases. The main odor generated by the influent lifting pump room of the sewage treatment plant is hydrogen sulfide, and the odor generated during the anaerobic digestion of the sludge in the primary sedimentation tank is mainly hydrogen sulfide and other sulfur-containing gases. This produces ammonia gas and other volatile substances. Ammonia, amines, sulfur compounds, fatty acids, aromatics, and dimethyl sulfide are produced during composting. The process of aerobic digestion and sludge air dryi...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the defects of the above-mentioned prior art, the present invention provides a photo-oxygen combined double-liquid double-spray washing deodorization reactor and its application method, which reduces the amount of chemical deodorizing agents used and the difficulty of handling, and saves operating costs. The design residence time of the chemical scrubber is reduced, the problem of ozone secondary pollution is completely solved, no need to increase the tail gas treatment device, and the guarantee rate of the treatment effect is improved
