Multiple groups of second bevel gears 7 are respectively meshed with the corresponding first bevel gears 5. A reaction chamber 8 is connected to the box body 1. The exhaust gas enters the reaction chamber 8 and contacts with the plasma. The plasma reacts with the exhaust gas to deodorize the exhaust gas. An opening 9 is opened at one end of the reaction chamber 8. The exhaust gas enters the reaction chamber 8 through the opening 9. The reaction chamber 8 is provided with a plasma. The sub-generator 13 and the plasma generator 13 are prior art and will not be described in detail here. A second mesh plate 12 is connected to the reaction chamber 8. The second mesh plate 12 prevents the plasma from contacting the exhaust gas to a certain extent. The impurities filtered in the exhaust gas fall onto the plasma generator 13. One end of the box body 1 is connected to an air inlet 14. The exhaust gas is injected into the box body 1 from the air inlet 14. One end of the box body 1 is connected to an air outlet 15. The filtered gas is discharged from the air outlet 15. One end of the box body 1 is rotatably connected to a threaded rod 10. Two groups of first mesh plates 4 are threadedly connected to one end with two groups of bolts 21. The bolts 21 are screwed into the box body 1 to fix the first mesh plate 4. The multiple groups of bolts 21 are threadedly connected to the box body 1. The first mesh plate 4 that needs to be replaced is isolated by rotating the baffle 3, and then the first mesh plate 4 is pulled out and replaced. To a certain extent, the first mesh plate 4 can be replaced without shutting down, thereby improving the exhaust gas treatment efficiency. The exhaust gas is subjected to multi-stage treatment by the first mesh plate 4 and the plasma generator 13, so that the exhaust gas meets the emission standards to a certain extent.

[0024] In this embodiment, the threaded rod 10 is threadedly connected to a plate 11, which is slidably connected to the outer wall of the reaction chamber 8.

If there are too many impurities adsorbed on the first mesh plate 4, which affects the filtration efficiency, the rod body 6 is rotated to make the second bevel gear 7 engage with the first bevel gear 5, and the baffle 3 is driven to move by the round rod 2 to isolate the first mesh plate 4 to be replaced. The bolt 21 is unscrewed from the box body 1, and the first mesh plate 4 is pulled out through the handle 20 to be replaced. The first mesh plate 4 can be replaced without stopping the machine, which improves the exhaust gas treatment efficiency to a certain extent. After being adsorbed by two groups of first mesh plates 4, the exhaust gas enters the reaction chamber 8 through the mouth body 9 and starts The plasma generator 13 ionizes the gas molecules to generate plasma. The active substances such as ions and free radicals in the plasma will chemically react with the pollutant molecules and undergo oxidation reactions with organic substances such as aldehydes and alcohols in the exhaust gas, converting them into harmless substances such as carbon dioxide. The threaded rod 10 is rotated to drive the plate body 11 to move, adjust the connection area between the mouth body 9 and the box body 1, and then adjust the flow rate of the gas entering the reaction chamber 8 so that the gas can fully contact the plasma. The exhaust gas is subjected to multi-stage treatment through the first screen plate 4 and the plasma generator 13, so that the exhaust gas meets the emission standards to a certain extent.
