Abstract

The invention discloses a sludge drying waste gas purification device for a sewage treatment plant. The device comprises a plurality of connecting pipes, a cyclone dust collector and integrated equipment. The cyclone dust collector is communicated with the integrated equipment through the connecting pipe. A primary spraying structure, a secondary spraying structure and a composite photocatalysis structure are arranged in the integrated equipment. Waste gas enters the cyclone dust collector from the connecting pipe to remove dust, then enters the integrated equipment and is sequentially washedby the primary spraying structure and the secondary spraying structure; and the washed waste gas is dehydrated and enters the composite photocatalysis structure to achieve organic matter decomposition. The purification effect on waste gas with large air volume, low concentration, high temperature and high protein dust content is good, and after treatment, the concentration monitoring indexes of dust, H2S, NH3, methyl mercaptan, dimethyl sulfide, methyl sulfide, methyl disulfide and foul smell at an exhaust port are far lower than the environment-friendly emission standard. The invention also relates to a sludge drying waste gas purification method for a sewage treatment plant.

Description

technical field [0001] The invention relates to waste gas purification, in particular to a sewage treatment plant sludge drying waste gas purification device. Background technique [0002] The composition of waste gas from sludge drying in sewage treatment plants is complex, the emission of flue gas is highly polluting, the discharge volume of waste gas is large, and the pollution components are complex and changeable. Hard to avoid. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the object of the present invention is to provide a sewage treatment plant sludge drying waste gas that can address the characteristics of sewage treatment plant sludge drying waste gas diversity, variability, high pollution concentration, and large processing capacity. Purification device. [0004] The object of the present invention adopts following technical scheme to realize: [0005] A sewage treatment plant sludge drying exhaust gas purification...
