A feeding chamber is arranged on one side of the biogas pit. The adjacent wall is pierced with a feeding pipe, the upper inlet of the feeding pipe is located in the feeding chamber, and the lower port extends into the lower part of the biogas digester. This device not only has a simple structure, but also has good heat insulation effect and good sealing performance.

Description

Biogas fermentation device

technical field

The utility model relates to a methane fermentation device.

Background technique

Nowadays, biogas digesters are generally made of concrete pouring and adopt hydraulic sealing test technology, which often has problems such as poor sealing performance and unstable pressure, which is not conducive to the construction and promotion of biogas digesters.

Contents of the invention

The purpose of the utility model is to provide a biogas fermentation device, which not only has a simple structure, but also has good heat insulation effect and good sealing performance.

The utility model comprises a brick biogas pit, the upper opening of the biogas pit is buckled with a glass fiber reinforced plastic sealing cover, the side of the biogas pit is provided with a feeding chamber, and the wall adjacent to the biogas pit is pierced by the feeding chamber. There is a feeding pipe, the inlet of the upper end of the feeding pipe is located in the feeding chamber, and the lower port extends into the lower part of the digester.

The remarkable advantages of the utility model are: first, the main body of the biogas pool is made of cement bricks, so the cost is low, and it is beneficial to build according to local conditions; The third is that the structure is compact and the layout is reasonable so as to realize the integration of the gas storage room and the fermentation room.

Description of drawings

Fig. 1 is a schematic diagram of the structure of an embodiment of the utility model.

Detailed ways

The embodiment of the utility model includes a brick biogas digester 1, a glass fiber reinforced plastic sealing cover 2 is buckled on the upper opening of the biogas digester, and a feeding chamber 3 is provided on one side of the biogas digester, and the feeding chamber is adjacent to the biogas digester. The wall is pierced with a feed pipe 4, the upper inlet of the feed pipe is located in the feed chamber, the lower port extends into the lower part of the biogas digester, the top of the glass fiber reinforced plastic sealing cover is provided with an exhaust port 5, and the glass fiber reinforced plastic sealing cover is a A drain pipe 6 is provided on the side.

When in use, pour the material into the feeding chamber, and when the material reaches a certain height, it flows into the biogas digester along the feeding pipe, and after being fermented in the closed biogas digester to generate biogas, the biogas is directly discharged from the exhaust port of the upper glass fiber reinforced plastic sealing cover for use. . The excess liquid is discharged from the liquid discharge pipe on the upper side of the glass fiber reinforced plastic sealing cover, thereby realizing the integration of the gas storage room and the fermentation body.

The utility model is novel in structure, reasonable in design, and has great popularization and application value.
