[0025] Reference Figures 1 to 6The steam inlet 3, exhaust gas inlet 4, and air guide inlet 7 are all compatible in specifications. The sealing slide plate 6 slides tightly against the bottom surface of the treatment box cover plate 2 via the sliding groove frame 5, so that either the steam inlet 3 or the exhaust gas inlet 4 can be flexibly selected to align and pass through the air guide inlet 7. The sealing slide plate 6 is controlled to move in parallel by the bow-shaped push rods 8 that are symmetrically fixed at both ends. The number and specifications of the push rod grooves 9 are compatible with the number and specifications of the bow-shaped push rods 8. They are symmetrically arranged on both sides of the exhaust gas treatment box 1. There are four sets of fixing screw holes 12, which are symmetrically arranged on the bottom surface of the treatment box cover plate 2. The number and specifications of the fixing bolts 11 are compatible with the number and specifications of the fixing screw holes 12. Each set of fixing bolts 11 passes through one of the four ends of the exhaust fan 10 and is connected to the corresponding bolt. The fixed screw hole 12 is screwed in for connection. Inside the waste gas treatment box 1, a water-holding frame 16 is set at the bottom of the activated carbon adsorption plate 15. A sealed side door 17 is hinged to one side of the waste gas treatment box 1. A drying air box 18 is set at the bottom of the waste gas treatment box 1. An exhaust port 19 is opened on one side of the waste gas treatment box 1. The position of the sealed side door 17 is adapted to the position of the water-holding frame 16, and the height of the sealed side door 17 is adapted to the thickness of the water-holding frame 16. The air outlet of the drying air box 18 is set to point towards the activated carbon adsorption plate 15. A support column 20 is fixedly connected to the bottom of the waste gas treatment box 1.

The bow-shaped push rod 8 pushes the sealing slide plate 6 to move it in the sliding groove frame 5 and aligns its air guide port 7 with the exhaust port 4. Then, the exhaust gas is introduced into the exhaust gas treatment box 1 by connecting the exhaust port 4 of the plastic production equipment through the external air guide pipe. The exhaust gas is then adsorbed by the activated carbon adsorption plate 15. After a period of use, the sealing slide plate 6 can be pushed to cover the exhaust port 4, and the air guide port 7 is aligned with the steam port 3. The steam generator 13 is started and the generated steam is passed through the steam generator. The conduit 14 is introduced into the interior of the exhaust gas treatment box 1 to clean the activated carbon adsorption plate 15. While removing pollutants, it also cleans the internal pores so that the activated carbon adsorption plate 15 can be reused, reducing consumption and avoiding resource waste. The water-holding frame 16 is used to hold the residual water or substances generated during the steam cleaning process, and can be taken out and emptied by opening the sealed side door 17. After the steam cleaning is completed, the drying air box 18 can be started to blow hot air upward to dry the activated carbon adsorption plate 15. The sealing slide plate 6 is closely attached to the bottom surface of the treatment box cover plate 2 through the sliding groove frame 5 and cooperates with the air guide port 7 to flexibly control the closing and opening of the steam port 3 and the exhaust gas port 4. The structure is simple and effective, and easy to operate and maintain.
