While the heat absorption plate 116 is cooling the exhaust gas, the water pump 117 is turned on to remove the toxic and harmful substances in the processing liquid storage box 110. The quality treatment liquid is sprayed into the processing box 13 through the No. 1 connecting pipe 111, the No. 3 connecting pipe 118 and the nozzle 119 to perform the primary treatment on the waste gas. At the same time, the surface of the heat absorbing plate 116 is cooled by the treatment liquid, so that the heat absorbing plate 116 can fully cool the waste gas. At the same time, the treatment liquid will flush the cooling water condensed on the surface of the heat absorbing plate 116 and the toxic and harmful substances adsorbed thereon, and the treated waste liquid is introduced into the collection box 113 for collection through the collection shell 114 and the No. 2 connecting pipe 115;
