The outer side of the adsorption box 4 is provided with a cover plate 5, and the four corners of the cover plate 5 are threadedly penetrated with a plurality of butterfly bolts 12, and the penetration end of the butterfly bolt 12 is threadedly connected with the threaded groove 13;

[0028] Specifically, when the adsorption layer 6 needs to be replaced, the butterfly bolt 12 threadedly connected on the cover plate 5 is rotated to take the butterfly bolt 12 out of the thread groove 13, and then the cover plate 5 is removed from the side wall of the adsorption box 4, and then the adsorption layer 6 inserted in the mounting hole 7 is pulled out, and then a new adsorption layer 6 is replaced and inserted into the mounting hole 7, and then the cover plate 5 is fixed to the adsorption box 4 by the butterfly bolt 12 again, thereby achieving the closure of the adsorption box 4, and the gas in the serpentine tube 9 is filtered and discharged by starting the negative pressure machine 8. The negative pressure machine 8 ensures that the serpentine tube 9, the purification box 3 and the adsorption box 4 are always in a negative pressure state, so that the exhaust gas in the serpentine tube 9 can flow.

[0029] Further, the heat recovery component includes a serpentine pipe 9, which is installed in the water tank 2, and the serpentine pipe 9 passes through the water tank 2 and is connected to the bottom of the purification box 3, and a one-way valve 11 is installed at the connection between the serpentine pipe 9 and the purification box 3;
