[0031] like Figure 3 and Figure 4As shown, the filtering and cleaning component 5 also includes a connecting tube 509 arranged inside the through pipe 1, and a motor 510 is fixedly installed at one end of the connecting tube 509, and the output end of the motor 510 and the connecting tube 509 are movably penetrated and extended to be connected with a first fan gear 511, and the outer wall of the connecting tube 509 is fixedly penetrated with multiple sleeves 512, and the interiors of the sleeves 512 are movably sleeved with shafts 513, which can improve the rotation stability of the shaft 513, and one end of the shaft 513 is fixedly connected with a second fan gear 514, and the second fan gear 514 is meshedly connected to the first fan gear 511, and the other end of the shaft 513 is rotatably connected to the inner wall of the through pipe 1, and the outer wall of the shaft 513 is fixedly sleeved with a cam 515, which is convenient for simultaneously linking multiple cams 515 to hit the filter plate 506 at the same time, thereby effectively cleaning the solid particles in the filter holes of the filter plate 506.

[0032] Furthermore, the cooling assembly 3 includes a connecting pipe 31 connected to one end of the through pipe 1, a cooling pipe 32 is arranged in the connecting pipe 31, and the cooling pipe 32 is spirally arranged, which can effectively and quickly cool down the exhaust gas emitted by the waste gas incinerator. One end of the cooling pipe 32 is connected to a water inlet pipe 33, and the other end of the cooling pipe 32 is connected to a drain pipe 34, which is convenient for the circulation of cooling water, thereby improving the cooling efficiency.

After the filter plate 506 is hit by the impact block 507, the sleeve block 504 is driven to slide on the outer wall of the guide rod 503 through the linkage rod 505, so that the guide rod 503 pushes the spring 508 to contract, thereby realizing the reset of the filter plate 506, so that the filter plate 506 can shake stably after being hit.

[0038] Finally, after the exhaust gas is filtered by the filter plate 506, it passes through the activated carbon filter layer 43 for adsorbing dioxins and other organic pollutants in the exhaust gas, the desulfurization layer 44 for removing sulfur dioxide and hydrogen chloride in the exhaust gas, and the denitrification layer 45 for removing nitrogen oxides in the exhaust gas, so that the exhaust gas meets the emission standards, thereby reducing the impact on the environment and improving the efficiency of exhaust gas emissions.
