NOVELTY - The utility model claims an afterheat recycling device for industrial waste gas treatment, comprising a bottom plate, the right side of the top part of the bottom plate fixedly connected with with a heating box; the left side of the top part of the bottom plate fixedly connected with with a processing box; the right side of the top part of the processing box fixedly connected with with a purifying box; the left side of the top part of the processing box fixedly connected with with a first fan; the input end of the first fan passes through the inner cavity of the processing box. The utility model sucks the high temperature waste gas in the processing box inner cavity through the input end of the first fan; the output end of the first fan sends the waste gas into the inner cavity of the purifying box; the graphene filtering net and PP fibre net filter the dust impurity and harmful substance in the waste gas; further purifying and sterilizing the high temperature waste gas by the plasma generator and the ultraviolet irradiation lamp; finally, the purified waste gas is sent back to the inner cavity of the heating box through the first conveying pipe; and the purified waste gas is recycled.
