Description

Technical Field

[0001] This utility model relates to the field of biogas filtration, specifically a biogas impurity coarse filtration device. Background Technology

[0002] Biogas, as a high-quality renewable energy source, is an inexhaustible energy source. It can be used to generate heat and electricity through combustion. Biogas can be produced locally using manure, waste leather, and other materials to generate electricity. The main component of biogas is methane, and it also contains carbon dioxide, hydrogen sulfide, and a small amount of particulate impurities. Generally, factories will perform a preliminary filtration after producing biogas to remove most of the carbon dioxide and particulate impurities.

[0003] Biogas impurity coarse filtration devices typically use gravel spraying to filter impurities and carbon dioxide in biogas. However, existing spraying mechanisms are not conducive to uniform spraying of gravel, resulting in uneven distribution of impurities in the gravel filter layer, which can easily cause local blockages. In addition, some areas may have fewer impurities, and the filtration effect may not be obvious. Therefore, a biogas impurity coarse filtration device is proposed to address the above problems.

The surface of the drain pipe 14 is fixedly fitted with a solenoid valve 15.

[0027] The spraying mechanism 3 includes a water tank 301 and a water pump 302. Both the water tank 301 and the water pump 302 are fixedly installed on the top of the housing 2. The input end of the water pump 302 is fixedly connected to an inlet pipe 303, one end of which is fixedly connected to the inner cavity of the water tank 301. The output end of the water pump 302 is fixedly connected to an outlet pipe 304, one end of which extends through the inner cavity of the housing 2 and is fixedly connected to a diversion pipe 305. One end of the diversion pipe 305 is fixedly connected to a first nozzle 306, and both sides of the diversion pipe 305 are fixedly connected to... A telescopic hose 307 is provided, with one end of the telescopic hose 307 fixedly connected to a second nozzle 308. One side of the second nozzle 308 is fixedly connected to the surface of the threaded sleeve 9. By setting up the spraying mechanism 3, the surface of the gravel 13 can be sprayed and humidified, filtering large particulate impurities in the biogas while also filtering carbon dioxide. During the spraying process, the motor 7 drives the bidirectional reciprocating screw 8 to rotate, which enables the two second nozzles 308 to move back and forth, achieving uniform spraying of the gravel 13, thereby improving its filtration quality and efficiency.

[0028] Reference Figure 5 Both sides of the water tank 301 are fixedly connected with retaining blocks 309, and the bottom of the retaining blocks 309 is fixedly connected to the top of the tank body 2. By setting the retaining blocks 309, the water tank 301 can be fixed and the position of the water tank 301 can be prevented from shifting during use.

[0029] Reference Figure 5A fixing ring 310 is fixedly sleeved on the surface of the water outlet pipe 304, and the bottom of the fixing ring 310 is fixedly connected to the top of the box 2. By setting the fixing ring 310, the water outlet pipe 304 can be fixed, thereby improving the stability of the water outlet pipe 304 in use.

[0030] Reference Figure 5 There are two second nozzles 308. Each of the two second nozzles 308 is fixedly connected to a sliding sleeve 311 on the other side. A sliding rod 312 is slidably connected to the inner cavity of the sliding sleeve 311. Both ends of the sliding rod 312 are fixedly connected to the inner wall of the limiting shell 6. By setting the sliding sleeve 311 and the sliding rod 312 to cooperate, the second nozzle 308 can be laterally limited to prevent the second nozzle 308 from shifting its position during movement.

[0031] Reference Figure 2 and Figure 3 Two guide blocks 16 are fixedly installed in the inner cavity of the box 2. The two guide blocks 16 are distributed opposite to each other in the inner cavity of the box 2.

[0032] Reference Figure 4 Dovetail blocks 17 are fixedly connected to both sides of the storage box 11, and the inner cavity of the fixing frame 10 is provided with a dovetail groove 18 that cooperates with the dovetail blocks 17. By setting the dovetail blocks 17 and the dovetail groove 18, the storage box 11 can be limited, thereby facilitating the installation and disassembly of the storage box 11 by the staff.

[0033] Reference Figure 2 A sealing plate 19 is rotatably connected to one side of the box 2 via a pivot pin, and one side of the sealing plate 19 is magnetically connected to the surface of the box 2. By setting the sealing plate 19, the box 2 can be sealed. At the same time, after the sealing plate 19 is opened, it is convenient for staff to replace the gravel 13 inside the storage box 11.

[0034] Working principle: During use, the operator starts the water pump 302 using an external control switch. The input end of the water pump 302 draws water from the inner cavity of the water tank 301 to the outlet pipe 304, and then flows into the first nozzle 306 and two second nozzles 308 through the diversion pipe 305, thus completing the spraying of the bottom gravel 13. During the spraying process, the output end of the motor 7 drives the bidirectional reciprocating screw 8 to rotate. When the bidirectional reciprocating screw 8 rotates, it drives the two threaded sleeves 9 to move back and forth on its surface. When the two threaded sleeves 9 move back and forth, they drive the two second nozzles 308 to move back and forth, so that the water can be sprayed evenly on the surface of the gravel 13, allowing the gravel 13 to fully exert its filtering effect and remove larger particulate impurities in the biogas. When the operator needs to replace the gravel 13, the sealing plate 19 is opened and the storage box 11 is taken out from the inner cavity of the fixed frame 10, so that the gravel 13 in the inner cavity of the storage box 11 can be replaced.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
