[0017] Step 1: The waste gas generated during the decomposition inside the processing tank is transported to the screening box through the air inlet pipe. The waste gas is pre-cooled when entering the screening box, so that part of the waste gas is converted into liquid. The liquid flows to the unloading flip plate by gravity. When one side of the unloading flip plate is subjected to gravity, the return spring is stretched, so that the unloading flip plate rotates to discharge the liquid into the collection frame.

[0018] Step 2: Preliminary screening of the exhaust gas is performed through multiple screening filter cartridges at the same time, so that particulate impurities in the exhaust gas are filtered out.

[0019] Step three, at the same time, clean the outside of the screening filter cartridge by installing a cleaning brush plate on the extrusion spring on one side of the long rod. When the conveying pipe rotates, the linkage pulley drives the linkage screw to rotate in both directions, so that the screw nut slide seat moves horizontally back and forth on the fixed guide round tube, so that the cleaning brush plate follows the movement, and the cleaning direction of the cleaning brush plate is changed. At the same time, the particulate impurities follow the condensed liquid on the outside of the screening filter cartridge to flow together and be collected centrally.

[0042] In a specific application scenario, the exhaust gas generated during the decomposition inside the processing tank 2 is transported to the sieve box 4 through the intake pipe 601. When the exhaust gas enters the sieve box 4, it is pre-cooled, so that a part of the exhaust gas is converted into liquid. The liquid flows to the blanking turnover plate 620 by gravity. When one side of the blanking turnover plate 620 is affected by gravity, the return spring 618 is stretched, causing the blanking turnover plate 620 to rotate automatically to discharge the liquid into the collection frame 628.

At the same time, the cleaning brush plate 626 on the extrusion spring 625 on one side of the installation long rod 624 is used to clean the outside of the sieve filter cylinder 604. While the conveying pipe 603 rotates, the linkage pulley 610 drives the linkage screw rod 623 to rotate bidirectionally, so that the screw nut slider one 622 reciprocates horizontally on the fixed guiding circular tube 621, causing the cleaning brush plate 626 to move accordingly, changing the cleaning direction of the cleaning brush plate 626 to improve the cleaning effect of the cleaning brush plate 626. While cleaning, the particulate impurities flow and are concentrated and collected together with the liquid condensed on the outside of the sieve filter cylinder 604. Through the sieve cleaning module 6, the structure of the filter mesh layer is changed, and at the same time, the filtering structure is cleaned, avoiding blockage that is likely to occur during long-term filtering and affecting the flow of exhaust gas, thereby improving the subsequent filtering and processing efficiency.

[0043] Refer to Figure 1 、 Figure 9 and Figure 10 Refer to

The inside of the circular hole six is connected with a fixed cylinder 809 through a bearing. A T-shaped tooth plate 810 is fixedly connected to the outside of the fixed cylinder 809. The tooth block end of the T-shaped tooth plate 810 meshes with the rotating gear 804. A notch is formed in one side of the T-shaped tooth plate 810. A driving motor 811 is fixedly connected to one side of the mounting seat 805. The driving end of the driving motor 811 is fixedly connected with a rotating push plate 812. A circular hole seven is formed in one side of the rotating push plate 812. A roller 813 is movably connected to the inside of the circular hole seven. The roller 813 slides inside the chute.

[0045] In a specific application scenario, the preliminarily filtered gas is discharged outward through the air outlet pipe 7. During the discharge process, the gas is purified by the activated carbon adsorption plate 808 and then discharged. A plurality of activated carbon adsorption plates 808 are provided. The installation sliding frame 806 is pulled by the pulling handle 807 to quickly replace the activated carbon adsorption plate 808. At the same time, when the gas flows in the air outlet pipe 7, by starting the driving motor 811, the driving motor 811 drives one end of the rotating push plate 812 to rotate in a circle. At this time, the roller 813 moves in the notch of the T-shaped tooth plate 810, causing the tooth block end of the T-shaped tooth plate 810 to rotate bidirectionally. The rotating gear 804 is driven by the T-shaped tooth plate 810, causing the flow regulating plates 803 on the multiple linkage cylinders 801 to swing, so that the gas evenly flows to the activated carbon adsorption plate 808, improving the adsorption effect of the activated carbon adsorption plate 808.

[0046] Refer to Figure 1 , a discharge fan body 9 is provided on one side of the air outlet pipe 7.

When the exhaust gas enters the sieving box 4, it is precooled, so that part of the exhaust gas is converted into liquid. The liquid flows to the blanking turning plate 620 by gravity. When one side of the blanking turning plate 620 is affected by gravity, the return spring 618 is stretched, causing the blanking turning plate 620 to rotate automatically to discharge the liquid into the collection frame 628.

[0049] Step 2: Meanwhile, the waste gas is preliminarily screened through multiple screening filter cylinders 604, so as to filter the particulate impurities in the waste gas. While filtering, the conveying pipe 603 drives the screening filter cylinders 604 to rotate bidirectionally inside the screening box 4, avoiding the liquid adhering to the outside of the screening filter cylinders 604 from blocking the screening holes;

[0050] Step 3: Meanwhile, the outside of the screening filter cylinders 604 is cleaned by the cleaning brush plate 626 on the compression spring 625 on one side of the installation long rod 624. While the conveying pipe 603 rotates, the linkage belt wheel 610 drives the linkage lead screw 623 to rotate bidirectionally, so that the lead screw nut sliding seat 622 reciprocates horizontally on the fixed guiding circular tube 621, causing the cleaning brush plate 626 to move accordingly and changing the cleaning direction of the cleaning brush plate 626. While cleaning, the particulate impurities flow and are centrally collected together with the liquid condensed on the outside of the screening filter cylinders 604.
