Biogas fermenting tank

Abstract

The invention discloses a biogas fermenting tank. The biogas fermenting tank comprises a main tank body, a liquid seal pool, an exhaust pipe, an air pressure adjustment chamber, a liquid discharge pipe, a shell breaking awl and a shell breaking grating. The main tank body is respectively communicated with the liquid seal pool and the air pressure adjustment chamber. The liquid seal pool is arranged at the top of the main tank body. The main tank body is provided with a diversion opening and a material discharge outlet. The exhaust pipe is arranged at the joint of the liquid seal pool and the main tank body and is communicated with the main tank body. The air pressure adjustment chamber is provided with an overflow mouth. The liquid discharge pipe is arranged at the joint of the liquid seal pool and the main tank body and is communicated with the main tank body. The shell breaking awl sleeves the liquid discharge pipe and is located in the main tank body. The shell breaking grating is arranged in the main tank body. The biogas fermenting tank is provided with the main tank body, the liquid seal pool, the exhaust pipe, the air pressure adjustment chamber, the liquid discharge pipe, the shell breaking awl and the shell breaking grating, has a compact and simple structure and prevents crusting phenomenon. The biogas fermenting tank has high anaerobic fermentation efficiency and a high biogas yield.

Description

technical field [0001] The invention relates to the field of domestic waste treatment, in particular to a biogas fermentation tank. Background technique [0002] At present, in the treatment of domestic waste, the more difficult ones mainly include organic waste and human excrement. Generally, organic waste includes sink waste and food waste. Sink waste is generally produced by food residues and vegetable and fruit peels entering the sewage pipe from the sink. This type of waste is difficult to recycle and is also prone to blockage of pipes. ; Food waste generally includes vegetable and fruit peels and food residues thrown into the trash can. This kind of garbage is easy to produce stench when placed in the open air, and because of its high water content, the cost of incineration or landfill treatment is too high. Generally, human excrement is directly passed into septic tanks, and after simple treatment, it is directly passed into rivers. In this way, more harmful microorg...

Generally, organic waste includes sink waste and food waste. Sink waste is generally produced by food residues and vegetable and fruit peels entering the sewage pipe from the sink. This type of waste is difficult to recycle and is also prone to blockage of pipes. ;Food waste generally includes vegetable and fruit peels and food residues thrown into the trash can. This kind of waste is prone to odor when placed in the open air, and because of its high water content, the cost of incineration or landfill treatment is too high

In general, human excrement is usually directly passed into the septic tank, and after simple treatment, it is directly passed into the river. In this way, more harmful microorganisms and excess nutrients will be brought in, which seriously threatens the water environment.

[0003] In addition, since these organic wastes and human excreta are rich in organic nutrients, they will be discharged without recycling, which will cause a great waste of social resources, which is not conducive to the main theme of the green and energy-saving society advocated today.

[0004] In response to the above problems, the traditional method is to add excreta to the biogas digester for anaerobic fermentation treatment. However, organic waste is generally not added to the biogas digester due to its complex composition and difficult operation, which has caused great In addition, the existing biogas is prone to crusting, resulting in a reduction in gas production and gas production rate
