The exhaust gas must pass through the auxiliary mesh cloth 704 so that the exhaust gas can fully contact with the auxiliary mesh cloth 704 containing the pretreatment liquid 104, thereby improving the pretreatment effect of the exhaust gas; the setting of four exhaust gas purification cottons 302 purifies the pretreated exhaust gas and ensures that the discharged gas meets environmental protection requirements; when the exhaust gas purification cottons 302 on the left and right sides need to be replaced, the pretreated exhaust gas passes through the resistance of the two exhaust gas purification cottons 302 When the pressure in the exhaust gas treatment shell 101 is greater than the elastic force of the two return springs 804, the rectangular movable cover 801 can slide forward under the pressure in the exhaust gas treatment shell 101; when the detection button 805 is pressed, the control panel 400 controls the servo motor 602 to work, so that the driving gear 603 drives the circular mounting cover 201 and the four exhaust bends 202 to rotate ninety degrees, thereby realizing the automatic replacement of the positions of the four exhaust gas purification cottons 302 and reducing the number of replacements; when the driving gear 603 drives the circular mounting cover 201 and the four exhaust bends 202 to rotate, the circular mounting cover 201 is in a circle of arc-shaped protrusions 1021 and a circle of arc-shaped grooves 2011 When the circular mounting cover 201 reciprocates up and down under the action of a circle of arc-shaped protrusions 1021 and a circle of arc-shaped grooves 2011, the auxiliary mesh 704 can also reciprocate up and down under the pulling action of the connecting wire rope 709 and the elastic force of the two supporting springs 706, so that the auxiliary mesh 704 moves in the pretreatment liquid 104, which plays an automatic cleaning role for the auxiliary mesh 704, is conducive to the falling of debris on the auxiliary mesh 704, and realizes the regular automatic cleaning of the auxiliary mesh 704; when the detection button 805 is pressed again after a certain interval, the servo motor 602 does not work under the action of the control panel 400, and the control panel 400 controls the buzzer alarm 500 to work, which can Automatically remind the staff to replace the four waste gas purification cottons 302; when the buzzer alarm 500 sounds, the staff will turn off the exhaust fan on the waste gas discharge pipe in the lightweight brick production area, and then pull down the four movable mounting frames 301, and then replace the four waste gas purification cottons 302; after the four waste gas purification cottons 302 are replaced, the control program on the control panel 400 is reset to ensure that the above working steps can be repeated when the detection button 805 is pressed again after a certain interval; when replacing the pretreatment liquid 104 in the waste gas treatment shell 101, first remove the drain screw 105 with a hexagonal wrench, wait for the pretreatment liquid 104 in the waste gas treatment shell 101 to be discharged, and reset the drain screw 105 with a hexagonal wrench;Then, the liquid inlet screw 106 is removed by a hexagonal wrench, and new pre-treatment liquid 104 is added into the exhaust gas treatment housing 101, and then the liquid inlet screw 106 is reset by a hexagonal wrench. ;
