The two layers of partitions 111 divide the body 11 into a first cavity, a second cavity and a third cavity from bottom to top. The body 11 includes at least two air inlet pipes 112 and an air outlet pipe 113 connected to the body 11. The air inlet pipe 112 is at least partially arranged in the first cavity, and the air outlet pipe 113 is at least partially arranged in the third cavity. The waste gas generated by the sludge enters the waste gas treatment device 100 from the air inlet pipe 112, and then is discharged from the air outlet pipe 113 after being purified by the waste gas treatment device 100. The waste gas generated by the sludge passes through the air inlet pipe 112, the first cavity, the second cavity, the third cavity and the air outlet pipe 113 on the waste gas treatment device 100. The waste gas collecting pipe 12 includes at least two, the waste gas collecting pipe 12 includes a feed port, a discharge port and a waste gas port connected to the air intake pipe 112 of the body 11. The waste gas collecting pipe 12 is used for sludge to flow through. The sludge enters the waste gas collecting pipe 12 from the feed port of the waste gas collecting pipe 12 and then flows out from the discharge port of the waste gas collecting pipe 12. The waste gas generated when the sludge flows through the waste gas collecting pipe 12 is discharged from the waste gas port through the air intake pipe 112 of the body 11 connected to the waste gas port and flows into the waste gas treatment device 100. The screen changing device 13 includes at least two screen changing devices 13, which are arranged at the penetration point of the partition 111. The exhaust gas in the exhaust gas treatment device 100 is filtered through the screen changing device 13. The partition 111 prevents the exhaust gas from directly flowing into the next cavity without passing through the screen changing device 13. On the other hand, the partition 111 is used to support the screen changing device 13 to improve the stability of the screen changing device 13 in the exhaust gas treatment device 100. The screen changing device 13 includes a filter cartridge 131 with a hollow accommodating cavity, a movable card slot 132, a hydraulic rod 133 for driving the movable card slot 132 to move, and a driving The driving member 134 of the hydraulic rod 133 and the net-changing switch door 135, the movable card slot 132 is used to accommodate the filter element, one end of the filter cartridge 131 is fixedly connected to the body 11, and the other end of the filter cartridge 131 penetrates the outside of the body 11, and the filter cartridge 131 is used to fix and place the movable card slot 132, and the movable card slot 132 is movable in the hollow accommodating chamber of the filter cartridge 131 through the hydraulic rod 133, and the filter element is detachably arranged in the movable card slot 132, and the driving member 134 is arranged outside the body 11, and the driving member 134 is connected to the hydraulic rod 133. The net-changing device 13 of the present application is arranged at the penetration on the partition 111, and the exhaust gas must pass through the net-changing device 13 when it flows from the lower cavity in the body 11 into the upper cavity. The net-changing device 13 can absorb and remove impurities in the exhaust gas and can treat the exhaust gas.Because the present application is provided with at least two screen changing devices 13, when the screen changing device 13 of the exhaust gas treatment device 100 needs to be cleaned, there is no need to shut down the exhaust gas treatment device 100, and it is only necessary to open the driving member 134 to control the hydraulic rod 133 to move. The moving hydraulic rod 133 drives the moving card slot 132 to move, thereby driving the filter element in the moving card slot 132 to move. When one of the screen changing devices 13 is cleaning and changing the element, the other screen changing device 13 is still adsorbing the exhaust gas. When one of the screen changing devices 13 is cleaned, the driving member 134 returns to its position and continues to treat the exhaust gas. At this time, the other screen changing device 13 can be cleaned and changed. By setting two screen changing devices 13, the present application can directly clean the screen changing device 13 of the exhaust gas treatment device 100 when it is cleaned, without shutting down the exhaust gas treatment device 100, thereby improving the exhaust gas cleaning efficiency and exhaust gas filtering efficiency of the exhaust gas treatment device 100.

Through such a setting, the exhaust gas passes through the screen changing devices 13 with different adsorption effects in turn, which can further improve the exhaust gas treatment and filtration effect of the exhaust gas treatment device 100.

[0020] As an implementation method, Figure 2As shown, the connection between the exhaust gas collecting pipe 12 and the machine body 11 includes a buffer pipe 121. The exhaust gas collecting pipe 12 is connected to the machine body 11 through the connection between the exhaust port and the air inlet pipe 112 of the machine body 11. The exhaust gas collecting pipe 12 is used to flow sludge. When the sludge flow rate is large, some sludge will flow from the air inlet pipe 112 into the machine body 11 of the exhaust gas treatment device 100, causing pollution to the machine body 11 of the exhaust gas treatment device 100. The present application is provided with a buffer pipe 121 at the connection between the exhaust gas collecting pipe 12 and the machine body 11.

The buffer pipe 121 is inclined, and the inclination direction of the buffer pipe 121 is opposite to the flow direction of the sludge. The angle between the buffer pipe 121 and the exhaust gas collecting pipe 12 is greater than or equal to 20° and less than or equal to 80°, and the height of the buffer pipe 121 is greater than or equal to 1m and less than or equal to 3m. The present application sets a buffer pipe 121 at the connection between the exhaust gas collection pipe 12 and the machine body 11. The buffer pipe 121 prevents sludge from flowing into the machine body 11 from the exhaust gas collection pipe 12. The angle range between the buffer tank and the exhaust gas collection pipe 12 and the height of the buffer pipe 121 are used to better prevent sludge from flowing into the machine body 11 from the exhaust gas collection pipe 12. Further, the angle between the buffer pipe 121 and the exhaust gas collection pipe 12 is greater than or equal to 30° and less than or equal to 60°, and the height of the buffer pipe 121 is greater than or equal to 1.5m and less than or equal to 2.5m.

[0021] As an implementation method, the waste gas gathering pipes 12 are connected by a plurality of connecting pipes 122. The waste gas gathering pipes 12 are used to flow through the sludge. The waste gas gathering pipes 12 of the present application include at least two. The waste gas treatment device 100 of the present application can at least treat the waste gas generated by the sludge in the two pipes. However, when the sludge flows through the waste gas gathering pipes 12, it may generate a large pressure and flow back into the body 11 of the waste gas treatment device 100 to pollute the body 11. The waste gas gathering pipes 12 are connected by a plurality of connecting pipes 122 in the present application. The sludge pressure of the waste gas gathering pipes 12 is reduced by connecting the waste gas gathering pipes 12 through the connecting pipes 122.

[0022] As an embodiment, an observation window 123 made of a transparent material is provided on one side of the buffer tube 121 close to the body 11. The buffer tube 121 is used to prevent the sludge in the exhaust gas collection pipe 12 from flowing back into the body 11 of the exhaust gas treatment device 100 and causing pollution to the body 11. The present application is provided with an observation window 123 made of a transparent material on one side of the buffer tube 121 close to the body 11. The observation window 123 is used to observe the sludge backflow in the buffer tube 121. When the sludge backflow level is observed to be high, the flow rate of the sludge in the exhaust gas collection pipe 12 can be reduced, the pressure of the sludge in the exhaust gas collection pipe 12 can be reduced, and the sludge backflow into the body 11 can be prevented.

[0023] As an embodiment, the machine body 11 includes an air extraction device 114, which is arranged at the air inlet pipe 112 of the machine body 11. The air extraction device 114 is arranged on the machine body 11 to extract the waste gas generated by the sludge in the waste gas collection pipe 12, which can improve the treatment degree of the sludge.

[0024] As an implementation method, Figure 3 As shown, a UV lamp 14 is disposed on one side of the third cavity. The UV lamp 14 disposed in the third cavity is used to further sterilize the waste gas passing through the two screen changing devices 13, thereby further improving the degree of waste gas treatment.
