[0027] In this embodiment, as shown in the figure, Figure 1 The lower side of the lifting plate 8 is provided with a first moving frame 12, the first moving frame 12 is slidingly connected to the upper end face of the gas collection and treatment box 1, the upper end face of the first moving frame 12 is symmetrically rotatably connected with a connecting rod 11, the connecting rod 11 is rotatably connected with the lower end face of the lifting plate 8 at the end away from the first moving frame 12, and the lower end face of the lifting plate 8 and the gas collection and treatment box 1 are fixedly connected with a spring 10 symmetrically, and the spring 10 is sleeved on the outer surface of the support column 9. When the first moving frame 12 moves on the upper end face of the gas collection and treatment box 1, the connecting rod 11 arranged can pull the lifting plate 8 to slide vertically downward on the outer surface of the support column 9, and at the same time, the spring 10 is extruded. Conversely, the rebound force of the spring 10 can push the lifting plate 8 to rise, and the first moving frame 12 is pulled to move reversely through the connecting rod 11.

With the movement of the second moving frame 22, the fixed plates 25 arranged can drive the spray heads 20 to move synchronously.

[0031] The effects achieved by this embodiment are as follows: in the prior art, in the traditional landfill gas collection and treatment system, a static method is usually used to promote the mixing of gas and liquid, but this method often has the problems of uneven mixing, short contact time, and low mixing efficiency, which causes the harmful substances in the gas to not be effectively dissolved or reacted in the liquid, resulting in insufficient mixing of the gas and the liquid. When the mixture is subjected to the subsequent filtering step, the filtering structure is easily blocked, which not only reduces the filtering efficiency but also increases the burden of the filtering structure and shortens its service life. Compared with the prior art, the baffle 27 can be pulled to slide and separate in the gas collection and treatment box 1 at regular intervals, so that the gas can be mixed with the liquid for a long time before being filtered through the filter plate 19, thereby promoting the sufficient mixing of the gas and the liquid, increasing the contact area and contact time between them, improving the mixing efficiency, and helping to ensure that the harmful substances in the gas can be more fully dissolved or reacted in the liquid, so that the filter plate 19 can more effectively trap these substances, thereby improving the filtering effect. At the same time, long-time mixing also helps to reduce the pressure difference during filtering and prolong the service life of the filter plate 19.

[0032] The working process and principles involved in the overall content of the above embodiments are as follows:

[0033] When the gas collecting and processing box 1 inhales the gas of the landfill, liquid is sprayed from the spray head 20 by the liquid conveying pipe 2 and the corrugated pipe 26 with the help of the external water pump, and is mixed with the gas in the gas collecting and processing box 1, and the driving motor 5 is turned on to drive the rotating shaft 4 to rotate, which can drive the pulley 6 to rotate synchronously through the connection between the rotating shaft 4 and the pulley 6, and the pulley 6 can drive the other pulley 6 to rotate synchronously through the belt 7 sleeved on the outer surface of the pulley 6, and the belt 7 moves around the outer surfaces of the two pulleys 6, and the belt 7 penetrates through the first moving frame 12, so that the fixed block 16 can drive the lever 17 to move synchronously during the movement of the belt 7 around the two pulleys 6, and when the lever 17 moves close to the first moving frame 12, the first moving frame 12 is driven to move horizontally on the upper end surface of the gas collecting and processing box 1, and the first moving frame 12 pulls the lower end of the connecting rod 11 connected symmetrically on the upper end surface to move synchronously, so that the connecting rod 11 moves from a vertical state to an inclined state, and the connecting rod 11 pulls the lifting plate 8 rotating away from the first moving frame 12 to slide downward on the outer surface of the supporting column 9 synchronously, and the spring 10 connected between the lifting plate 8 and the gas collecting and processing box 1 is compressed, and the lifting plate 8 pushes the connecting plate 14 away from the gas collecting and processing box 1 through the linkage plate 13 connected on both sides, and the slide column 15 slides out of the gas collecting and processing box 1, and the slide column 15 pulls the baffle 27 connected in the gas collecting and processing box 1 to move away from each other synchronously, so that the filter plate 19 on the partition plate 18 is no longer blocked, and the gas mixed with the liquid can be discharged through the filter plate 19, so that the gas and the liquid are fully mixed and discharged automatically, thereby promoting the full mixing of the gas and the liquid, increasing the contact area and contact time between the two, improving the mixing efficiency, and helping to ensure that the harmful substances in the gas can be more fully dissolved or reacted in the liquid, so that the filter plate 19 can more effectively trap these substances, thereby improving the filtering effect, and at the same time, long-time mixing can also help to reduce the pressure difference during filtering, prolonging the service life of the filter plate 19;

[0034] When the dial lever 17 follows the belt 7 away from the first moving frame 12, the push force of the first moving frame 12 disappears at this time, and the spring 10 sleeved on the outer surface of the supporting column 9 rebounds to push the lifting plate 8 to automatically rise. In the process of the lifting plate 8 rising, not only the first moving frame 12 can be moved to the initial position through the connecting rod 11 arranged, but also the slide column 15 can be pushed into the gas collection and treatment box 1 again through the linkage plate 13 and the connecting plate 14 arranged, so that the baffles 27 in the gas collection and treatment box 1 are close to each other, the filter plate 19 is blocked, and the situation that the gas and the liquid are mixed for a short time and discharged through the filter plate 19 is avoided.

[0035] In the process that the rotating shaft 4 drives one of the pulleys 6 to rotate, the dial plate 21 connected to the lower end of the rotating shaft 4 rotates synchronously, and the cylinder 23 rotates synchronously with the rotating shaft 4 as the center. Since the cylinder 23 is slidably connected in the sliding groove 24 arranged on the upper end surface of the second moving frame 22, and the second moving frame 22 is slidably connected to the top of the gas collection and treatment box 1, in the process that the cylinder 23 moves, the second moving frame 22 can slide back and forth in the sliding groove 24, and the second moving frame 22 can be driven to move horizontally on the top of the gas collection and treatment box 1 through the sliding groove 24. Since the second moving frame 22 is connected to the fixed plate 25 and the nozzle 20, and the corrugated pipe 26 is connected between the nozzle 20 and the liquid conveying pipe 2, when the second moving frame 22 moves horizontally, the nozzle 20 can be driven to move in the gas collection and treatment box 1 through the fixed plate 25, the range of the liquid sprayed by the nozzle 20 is increased, so that the liquid can be uniformly sprayed to each corner in the gas collection and treatment box 1, the gas is fully mixed with the liquid to form a more stable mixture, and the efficiency of the chemical reaction or the physical adsorption is improved, so that the harmful substances in the gas can be more effectively absorbed or converted by the liquid.

The preferred embodiments do not describe all the details, and the utility model is not limited to the specific embodiments described. Obviously, according to the content of the specification, many modifications and changes can be made.
