Waste heat recovery device for environmental engineering waste gas treatment

The utility model discloses a waste heat recovery device for environmental engineering waste gas treatment. Box body, the top of the box body is fixedly connected with a shell. An air pump is fixedlymounted at the top of the box body and located on one side of the shell; the air inlet end of the air pump is communicated with one side of the shell; an inner cavity of the box body is divided into afirst cavity and a second cavity through a partition plate, the air outlet end of the air pump communicates with a pipeline, the bottom of the pipeline penetrates through the box body and extends tothe inner cavity of the first cavity, the bottom of the pipeline communicates with a transverse pipe, the bottom of the transverse pipe communicates with a vertical pipe, and a sealing plate is fixedly connected to the upper portion of the first cavity. Toxic gas and dust in waste gas are adsorbed through the activated carbon in the shell, then hot gas enters the transverse pipe through the pipeline, enters the vertical pip
