[0024] In this embodiment, during the RCO catalytic combustion process, the exhaust gas needs to be pre-treated. At this time, the exhaust gas is allowed to enter the tank body 1 through the air inlet pipe 6, and the designated water pump is connected to the water inlet pipe 17. After the water pump is started, the purified liquid can be sprayed out in an atomized state at the nozzle 9. There is no mandatory requirement for the number of nozzles 9 here. It can provide a spraying effect for the exhaust gas and purify the impurity particles in the exhaust gas. The mixed liquid will be stored at the bottom of the tank body 1. The purified exhaust gas will enter the exhaust shell 5 at the filter plate 16.

The driving block 11 can drive the driven ring 13 to rotate through the engagement, and then the scraper rod 12 can rotate under the shell 7, so that the scraper rod 12 can provide a scraping effect to the inner wall of the tank body 1, so that impurities are not easily attached to the inner wall of the tank body 1.

[0026] In this embodiment, a frame 15 is provided inside the cavity 14, the frame 15 is threadedly connected to the cavity 14, and the filter plate 16 is adhered to the frame 15. After the exhaust shell 5 is disassembled, the frame 15 is rotated and the frame 15 can be taken out of the cavity 14, so that the filter plate 16 can be easily replaced.

[0027] In this embodiment, the exhaust shell 5 is fixed to the outer wall of the tank body 1 by screws, the top cover 2 is fixed to the top of the tank body 1 by bolts, and the bottom shell 3 is fixed to the bottom of the tank body 1 by bolts. The bolt and screw fixing method has the advantage of convenient assembly, which can facilitate the assembly of the top cover 2, the bottom shell 3 and the exhaust shell 5 on the tank body 1.
