Positioning holes are provided on one side of the filter screen 701 and the activated carbon adsorption plate 702, and the two positioning holes are adapted to the positioning rods 707. When the two positioning rods 707 are inserted into the two positioning holes, the positions of the filter screen 701 and the activated carbon adsorption plate 702 are fixed, and it is convenient for replacement. Under the action of the filter screen 701 and the activated carbon adsorption plate 702, the particulate matter in the exhaust gas is preliminarily intercepted and adsorbed.

[0025] The drainage assembly 5 includes a water pump 501 fixedly installed on the top of the high-temperature box 1 , a water suction pipe 502 is installed between the inlet of the water pump 501 and the high-temperature box 1 , and a delivery pipe 503 is installed at the outlet of the water pump 501 .
