[0024] With reference to Figure 4The adjusting assembly 14 comprises a motor 141 fixedly connected on one side of a mounting frame 145, a first lead screw 144 rotatably connected in the mounting frame 145, one side of the moving plate 12 is threadedly connected with the first lead screw 144, the output end of the motor 141 is fixedly connected with a first gear 142, one side of the first gear 142 is meshedly connected with a second gear 143, and one side of the second gear 143 is fixedly connected with one side of the first lead screw 144. When the assembly plate 13 needs to drive the first and second guide plates 3 and 4 to move, the motor 141 is used to drive the first gear 142 to rotate, the first gear 142 drives the second gear 143 to rotate, and the second gear 143 drives the first lead screw 144 to rotate, so that the moving plate 12 drives the assembly plate 13 to move, and the first and second guide plates 3 and 4 are extended out of the first treatment box 1, facilitating subsequent maintenance.

[0026] Use principle and advantage: The waste gas produced in the production process of sludge ceramic is introduced into the first treatment box 1 through the air inlet pipe 2. The waste gas first contacts the first flow guide plate 3, and the filter cloth 31 fixed on both sides of the first flow guide plate 3 plays a physical filtering role to intercept large-particle pollutants such as dust, ceramic chip and the like in the waste gas. Subsequently, the waste gas flows through the second flow guide plate 4, and the activated carbon adsorption layer 41 coated on both sides of the second flow guide plate 4 removes harmful gases and volatile organic compounds in the waste gas by using the adsorption effect of the adsorbent. Since the first flow guide plate 3 and the second flow guide plate 4 are provided with multiple groups, the pollutants in the waste gas can be fully treated. The first flow guide plate 3 and the second flow guide plate 4 are alternately arranged in an inclined manner, which delays the passing time of the waste gas, so that the dust and other pollutants have more opportunities to contact the filter cloth 31 and the activated carbon, thereby improving the treatment effect of the dust in the waste gas. The pretreated waste gas is introduced into the second treatment box 11 through the first air guide pipe 5, the connecting pipe 6 and the second air guide pipe 7. In the second treatment box 11, the pretreated waste gas is further treated by the spray head 8. The water vapor sprayed by the spray head 8 fully contacts the remaining dust in the waste gas to remove the dust. The sewage is filtered by the filter screen 10, and the treated waste gas is discharged through the exhaust pipe 9. When the first flow guide plate 3 and the second flow guide plate 4 need to be maintained, the motor 141 drives the first gear 142 to rotate, the first gear 142 drives the second gear 143 to rotate, and the second gear 143 drives the first lead screw 144 to rotate. Therefore, the movement of the moving plate 12 will drive the assembly plate 13 and the first flow guide plate 3 and the second flow guide plate 4 to move together, so that they are stretched out of the first treatment box 1. After the assembly plate 13 is completely stretched out of the first treatment box 1, rotating the torsion wheel 1552 will drive the second lead screw 1551 to rotate, the sliding blocks 1553 on both sides of the second lead screw 1551 move, the sliding blocks 1553 drive the moving rods to move, and further drive the positioning rods 154 to move away from the positioning holes 153 in the butt joint blocks 152. At this time, the butt joint blocks 152 and the butt joint grooves 151 are no longer fixed, and the assembly plate 13 and the first flow guide plate 3 and the second flow guide plate 4 can be removed for maintenance.
