The middle part of the gas confluence pipe 8 is fixedly connected with the main outlet pipe 10. Specifically, after the exhaust gas enters the corresponding adsorption box 1 through the gas diversion pipe 6, it can be filtered in two stages by the two activated carbon adsorption filter elements 4 in the corresponding adsorption box 1, and after filtration, it enters the gas confluence pipe 8 through the outlet pipe 3, and then is discharged through the main outlet pipe 10;

[0024] Two slide rails 11 are fixed inside the adsorption box 1, and frames 12 are slidably connected inside the slide rails 11. Two activated carbon adsorption filter elements 4 are respectively fixed in the two frames 12. The front ends of the frames 12 penetrate the front end of the adsorption box 1, and handles 13 are fixed to the front ends of the frames 12.
