Description

Technical Field

[0001] The invention belongs to the technical field of gas power generation, and in particular relates to a low-concentration gas power generation mixing device. Background Art

[0002] Coalbed methane is called coal mine gas in coal mines. According to the new resource evaluation results, the main component of coalbed methane is methane. When the concentration of methane in the air reaches 5%-16%, it will explode when encountering open flames. This is the root cause of coal mine gas explosion accidents. If coalbed methane is not utilized and directly discharged into the atmosphere, its greenhouse effect is about 21 times that of carbon dioxide. Coal mine gas power generation can effectively solve coal mine gas accidents and improve coal mine safety production conditions, but also help increase the supply of clean energy and reduce greenhouse gas emissions, achieving the multiple goals of protecting life, protecting resources, and protecting the environment.

Mixing components are connected to the middle of both sides of the inner wall of the second mixing cylinder 12, and a gas collecting component is connected to the upper end of the inner wall of the second mixing cylinder 12. The conveying component includes a fixed tube 5, and the fixed tube 5 is circumferentially connected to the first dispersion tube 8, so as to disperse the gas and air in the fixed tube 5 into the first mixing cylinder 3. The upper ends of multiple first dispersion tubes 8 extend through the first mixing cylinder 3, and the upper ends of the fixed tubes 5 are circumferentially connected to the second dispersion tubes 9. One end of multiple second dispersion tubes 9 extends through the first mixing cylinder 3. The middle of both sides of the inner wall of the first mixing cylinder 3 is rotatably connected with a connecting shaft 10, and the outer side of the connecting shaft 10 is circumferentially connected with a connecting blade 11. The gas discharged from the two dispersion pipes 9 blows the connecting blades 11 to rotate, so that the gas and air can be mixed. A gas inlet pipe 6 is connected to the middle of one side of the fixed pipe 5, and one end of the gas inlet pipe 6 extends through to one side of the support tube 2. An air inlet pipe 7 is connected to the middle of the side of the fixed pipe 5 away from the gas inlet pipe 6, and one end of the air inlet pipe 7 extends through to one side of the support tube 2. A first valve 26 is connected to the outer side of the gas inlet pipe 6, and a second valve 27 is connected to the outer side of the air inlet pipe 7.

At the same time, some gas moves upward and contacts the lower end of the guide ring 14, forming convection to cause the gas to move downward, and continues to blow the multiple connecting blades 11 and the connecting shaft 10 to rotate, so that the multiple connecting blades 11 continue to rotate, so as to better mix the gas and the air. The gas is transported to the inside of the second mixing cylinder 12 through the opening 13, and the gas is concentrated at the opening 13 and moves upward, so as to blow the multiple rotating blades 17 to rotate, so that the two rotating rods 16 rotate, and drive the multiple rotating blades 17 to rotate, so that the gas and the air are mixed again, the first valve 26 and the second valve 27 are in a closed state, the air pump 22 is working, and the multiple collecting heads 20 collect the gas inside the second mixing cylinder 12, and the gas enters the collecting pipe 19, and then the gas inside the collecting pipe 19 is transported to the gas inlet pipe 6 through the conveying pipe 21 and the connecting pipe 23, and enters the fixed pipe 5 again through the gas inlet pipe 6, so that the gas and the air circulate again and enter the first mixing cylinder 3 and the second mixing cylinder 12 to be mixed again. After the secondary mixing is completed, the exhaust valve 25 is opened, and the mixed gas is discharged through the exhaust pipe 24.
