The cavity between the first partition 102 and the second partition 103 is a transition chamber 104. The cavities on the side away from each other of the first partition 102 and the second partition 103 are respectively a liquid adsorption chamber 105 and a filter chamber 106. Liquid is arranged in the liquid adsorption chamber 105 for adsorbing impurities in the tail gas. A drain pipe is connected to the bottom of one side of the liquid adsorption chamber 105. A valve is installed on the drain pipe to facilitate the replacement of the liquid.

A take-in and put-out port 109 is opened at a side of the processing box 101 close to the filter chamber 106 and at a position corresponding to the upper limit frame 107 and the lower limit frame 108.

[0029] Intake pipe 200, such as Figure 1 One end of the air inlet pipe 200 extends into the bottom of the liquid adsorption chamber 105, and the other end extends to the outside of the treatment box 101 and is fixedly connected to the treatment box 101.

A threaded sleeve 607 is spirally connected to the screw 606, and a clamping plate 608 is fixedly connected to the outer wall of the threaded sleeve 607. A clamping groove 609 is opened on one side of the fixing rod 605. The clamping plate 608 is placed in the clamping groove 609 and abuts against the inner wall of the clamping groove 609 on the side away from the fixing plate 603. Through the abutment between the clamping plate 608 and the clamping groove 609, the fixing plate 603 can be fixed, so that the blocking block 601 is not easy to fall out of the taking and releasing port 109, thereby ensuring the sealing of the taking and releasing port 109.

[0037] Furthermore, a protruding fixing rod 605 is provided on the side of the clamping plate 608 away from the threaded sleeve 607. The advantage of such a configuration is that the protruding portion can facilitate the rotation of the clamping plate 608, thereby facilitating the separation of the clamping plate 608 from the clamping groove 609, thereby facilitating the release of the fixing plate 603. A handle 610 is fixedly connected to the side of the fixing plate 603 away from the blocking block 601. By providing the handle 610, the fixing plate 603 can be conveniently driven to retreat, thereby facilitating the removal of the blocking block 601 from the access opening 109 through the fixing plate 603.

[0038] In summary, when the incineration exhaust gas is treated, the incineration exhaust gas is introduced into the liquid adsorption chamber 105 through the air inlet pipe 200, and after being adsorbed and cooled by the liquid in the liquid adsorption chamber 105, it enters the filter chamber 106 through the air guide pipe 300, and is filtered through the third filter screen plate 503, the second filter screen plate 502 and the first filter screen plate 501 in sequence, and then discharged through the air outlet pipe 400 to complete the treatment. When it is necessary to clean the filter assembly 500, rotate the clamping plate 608 and make the clamping plate 608 completely disengage from the clamping groove 609 (such as Figure 7 ), and then pull the fixed plate 603 to move through the handle 610, the fixed plate 603 drives the blocking block 601 to move, and the blocking block 601 is disengaged from the access port 109. After disengaging, the filter assembly 500 is pulled through the access port 109 to be pulled out from between the upper limit frame 107 and the lower limit frame 108. After being pulled out, the filter assembly 500 is disassembled, and the third filter screen plate 503, the second filter screen plate 502 and the first filter screen plate 501 are cleaned respectively. The overall operation is simple, less time-consuming, and can improve the cleaning efficiency.
