Background

Biogas is a combustible gas produced by the fermentation of organic substances in an anaerobic environment under the conditions of certain temperature, humidity and pH value.

The farms can generate a large amount of excrement every day, if the excrement is treated in a direct composting way, the excrement can cause the odor of the composting site, the breeding of mosquitoes and flies and the turbulent flow of excrement water to pollute the environment, and the generated biogas is directly discharged into the atmosphere, so that the resource waste is caused. Composting is performed at a slower rate, often requiring a larger area.

A communication hole 11 is arranged between the second partition plate 7 and the bottom of the tank body 1, the upper ends of the first partition plate 7 and the third partition plate 8 are the same in horizontal height, and the upper ends of the second partition plate 7 are higher than the upper ends of the first partition plate 6 and the third partition plate 8; a cross plate 9 and a first inclined plate 10 are located between the second partition plate 7 and the third partition plate 8, and the cross plate 9 and the first inclined plate 10 are fixed to the side wall of the cell body 1. The first inclined plate 10 is located above the cross plate 9.

A second inclined plate 12 is provided above the first inclined plate 10, and the second inclined plate 12 is fixed to a side wall of the cell body 1. The second inclined plate 12 is perpendicular to the first inclined plate 10.

A first heating pipe 13 is provided between the first partition plate 6 and the second partition plate 7, and the first heating pipe 13 is inserted into the tank 1 from the top of the tank 1. A second heating tube 14 is arranged between the second partition plate 14 and the third partition plate 8, the second heating tube 14 being connected to the first heating tube 13. The second heating pipe 14 is inserted from the top of the tank body 1 to the outside of the tank body 1. The first heating pipe 13 is connected with a hot water outlet of the solar water heater, the second heating pipe 14 is connected with a return pipe, the return pipe is connected with a water inlet of the solar water heater, and a booster pump is arranged on the return pipe.
