Technical Field

[0001] This utility model belongs to the field of biogas purification technology, and specifically relates to a biogas purification device. Background Technology

[0002] Biogas is a combustible gas produced by the fermentation of various organic substances under anaerobic conditions by microorganisms. Biogas is mainly composed of methane and carbon dioxide, but in actual production, it also contains harmful substances and impurities such as hydrogen sulfide, which can easily pollute the environment and requires purification before use.

[0003] However, in the current desulfurization and purification process of biogas, the sulfurizing agent filling plate is usually fixed inside the purification box by bolts. After the purification device has been used for a long time, it is usually troublesome, time-consuming and labor-intensive to replace and disassemble it. Now, a biogas purification device is provided to alleviate the above-mentioned problems. Summary of the Invention

[0004] This invention utilizes a desulfurization plate disassembly and assembly device to move the movable frame out of the purification box, thereby achieving the purpose of quickly replacing the desulfurizing agent filling plate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0024] Please see Figure 1-4A biogas purification device includes a purification box 1. An air inlet pipe 7 and a liquid inlet pipe 8 are fixedly installed on the side of the purification box 1, with the air inlet pipe 7 located above the liquid inlet pipe 8. A circulating spray mechanism 4 is installed on the other side of the purification box 1. The circulating spray mechanism 4 includes a circulating pipe 401. The circulating pipe 401 is fixedly installed at the lower end of the side of the purification box 1, and the other end of the circulating pipe 401 extends upward and is fixedly connected to an atomizing spray pipe 403. The atomizing spray pipe 403 is horizontally arranged inside the purification box 1 and is fixedly connected to the purification box 1. A one-way valve 402 is installed above the circulating pipe 401, which can spray desulfurization treatment liquid downward through the circulating spray mechanism 4 to desulfurize the overflowing biogas again.

[0025] Please see Figure 1-4 Support rods 11 are fixedly connected to the bottom of the purification box 1 near the four corners. Support bases are fixedly connected to the bottom of the support rods 11. The two ends of the partition 2 are fixedly connected to the two sides of the inner wall of the purification box 1. A stirring mechanism 3 is set below the partition 2. An exhaust pipe 10 is fixedly installed on the top of the purification box 1. A desulfurization plate disassembly and assembly device 5 is set above the atomizing spray pipe 403. The desulfurization plate disassembly and assembly device 5 includes a limiting slide groove 501. The limiting slide groove 501 is fixedly set on the inner wall of the purification box 1. A moving frame 502 is movably set on the inner side of the limiting slide groove 501. A handle 504 is fixedly connected to one side of the moving frame 502 through the side wall of the purification box 1. A desulfurizing agent filling plate 503 is fixedly set on the inner side of the moving frame 502. A drying plate 6 is detachably installed inside the purification box 1 above the desulfurization plate disassembly and assembly device 5.

[0026] Furthermore, a docking groove is provided on the inner wall away from the handle 504, and the movable frame 502 can be movably inserted into the limiting slide groove 501 through the docking groove. A groove matching the size of the movable frame 502 is provided on one side of the purification box 1, and the groove penetrates the side wall of the purification box 1. In this embodiment, by pulling the movable frame 502, the movable frame 502 can slide in the limiting slide groove 501, thereby achieving the effect of pulling out the movable frame 502, and thus realizing the timely replacement of the desulfurizing agent filling plate 503.

[0027] Please see Figure 1-4The stirring mechanism 3 includes a first stirring shaft 303, which is rotatably mounted inside the purification box 1. A fixing plate 301 is fixedly mounted on the bottom of the purification box 1. A motor 302 is fixedly mounted on one side of the fixing plate 301. The output end of the motor 302 passes through the bottom of the purification box 1 and is fixedly connected to the bottom end of the first stirring shaft 303. Symmetrically distributed first stirring rods 305 are fixedly connected to the surface of the first stirring shaft 303. Several groups of first stirring rods 305 are arranged at equal intervals along the first stirring shaft 303. A connecting plate 309 is sleeved on the surface of the first stirring shaft 303 located below all the first stirring rods 305. A second stirring shaft 304 is connected through the top of the other side of the connecting plate 309. Symmetrically distributed second stirring rods 306 are fixedly connected to the surface of the second stirring shaft 304. Several groups of second stirring rods 306 are arranged at equal intervals along the second stirring shaft 304.

[0028] In this embodiment, by setting a fixed plate 301, a motor 302, a first stirring shaft 303, a second stirring shaft 304, a first stirring rod 305, and a second stirring rod 306, the second stirring shaft 304 revolves around the first stirring shaft 303, which improves the flexibility of the stirring shaft and enables the biogas and desulfurization liquid at the bottom of the inner cavity of the purification box 1 to be fully mixed, thereby improving the purification effect of the desulfurization liquid on the biogas.

[0029] Please see Figure 1-4 The stirring mechanism 3 also includes a toothed ring 308. The bottom of the purification box 1 is fixedly connected to the toothed ring 308, and the inner wall of the toothed ring 308 is meshed with a gear 307. The gear 307 is fixedly sleeved on the outer side of the bottom end of the second stirring shaft 304. By setting the toothed ring 308 and the gear 307 to cooperate, the flexibility of the second stirring shaft 304 is improved, which can further fully mix the biogas and the desulfurization treatment liquid.

[0030] Working principle: In use, the unpurified biogas and desulfurization liquid are first transported into the purification tank 1 through the air inlet pipe 7 and the liquid inlet pipe 8, respectively. Then, the drive motor 302 works, driving the first stirring shaft 303 and the first stirring rod 305 to rotate. The first stirring shaft 303 drives the second stirring shaft 304 and the second stirring rod 306 to rotate through the connecting plate 309. The second stirring shaft 304 drives the gear 307 to rotate. The gear 307 cooperates with the gear ring 308, so that the second stirring shaft 304 revolves around the first stirring shaft 303, which fully mixes the biogas and desulfurization liquid in the inner cavity of the purification tank 1. At the same time, the one-way valve 402 is activated to transport the desulfurization liquid in the purification tank 1 to the atomizing spray pipe 403 through the circulation pipe 401 and spray it out to desulfurize the biogas overflowing from the desulfurization liquid again.

[0031] The desulfurized biogas will enter the desulfurizing agent filling plate 503 through several sets of through holes in the partition plate 2 for further purification. After being dried by the drying plate 6, the purified biogas will be transported to an external container for storage through the gas outlet pipe 10. When the desulfurizing agent filling plate 503 needs to be replaced, pull the handle 504 to move the moving frame 502 out of the purification box 1 for replacement, which helps to improve the performance of the desulfurizing agent filling plate 503.
