Abstract
The utility model provides a multilayer waste gas purification reactor. The multilayer waste gas purification reactor comprises a frame, a front filter plate, a rear filter plate and multiple electric catalyst conversion units, wherein the frame comprises an input end and an output end, the front filter plate and the rear filter plate are respectively close to the input end and the output end, respectively comprise multiple filtration regions for bearing the multiple electric catalyst conversion units and multiple hollow circulation regions and are separated from each other to be staggered, and the input end, the circulation regions of the front and rear filter plates, and the output end form a waste gas circulation passageway. Accordingly, the electric catalyst conversion units are exposed to the passageway to serve as a reaction side for purifying waste gas, and a reducing gas system is not needed, so that the size and the production cost of the multilayer waste gas purification reactor are reduced.
