Method for producing biogas in disordered turbulent biogas fermentation system

Abstract

The invention discloses a method for producing biogas through a disordered turbulence type super-high-efficiency biogas fermentation system. The method is characterized by comprising the steps: pushing biogas slurry to flow to an adjacent fermentation area when the biogas is produced in a fermentation area between the side wall of a feeding / discharging pipe and a gas baffle or a fermentation area formed between adjacent gas baffles in an annular fermentation pipeline; allowing the biogas produced by continuous fermentation to flow into an adjacent fermentation area which is not filled with biogas until the fermentation areas are communicated with one another when the fermentation area is filled with biogas; allowing the biogas produced by continuous fermentation to overflow from the fermentation system and discharge into atmosphere when the liquid level of the biogas slurry in the annular fermentation pipeline reaches the lowest position of the side wall of the feeding pipe or discharging pipe; and allowing the liquid level of biogas slurry in the feeding pipe, the discharging pipe and the bacteria distribution device to continuously ascend in the process of producing biogas in the annular fermentation pipeline, and allowing the biogas slurry to flow into the water pressure room by virtue of the drainage pipe of the feeding pipe, the drainage pipe of the discharging pipe and the bacteria distribution device.

Description

technical field [0001] The invention relates to a generating device, in particular to a fermentation system in the technical field of biogas. Background technique [0002] The hydraulic biogas digester type has the following advantages: (1) The structure of the pool body has good mechanical performance, and makes full use of the bearing capacity of the soil, so it saves labor and materials, and the cost is relatively low; (2) It is suitable for filling a variety of fermentation Raw materials, especially a large amount of crop stalks, are very beneficial to the accumulation of manure in rural areas; (3) To facilitate frequent feeding, toilets and pig pens can be built on the biogas digester, and feces can be cleaned into the pond at any time; (4) Surrounding the biogas digester Contact with the soil has a certain effect on the heat preservation of the pool body. [0003] Since there is no stirring device in the hydraulic biogas digester, the scum in the tank is easy to crust...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the traditional biogas fermentation system has a short fermentation route, and the poor fluidity of the biogas slurry leads to uneven separation of strains and easy crusting, and incomplete fermentation of fermentation materials, etc.
