Through the guiding effect of the diverter plate 12 and the guide block 11, the exhaust gas that has been adsorbed and purified by the adsorption plate 14 twice completes the reverse flow and flows out again, realizing multi-level exhaust gas purification treatment;

[0026] The main pipe 4 is connected with several branch pipes 6, each branch pipe 6 is connected with the suction hood 5, and the suction hood 5 is a bucket-shaped plastic structure with an opening facing downward.
