Efficient biogas fermentation device capable of performing disorder type biogas slurry mixing and convective stirring

Abstract

The invention discloses an efficient biogas fermentation device capable of performing disorder type biogas slurry mixing and convective stirring. The efficient biogas fermentation device comprises a feed pipe, a discharge pipe, a fermentation pipeline and a water pressure chamber, wherein the feed pipe and the discharge pipe are vertically inserted into two sides of a clapboard respectively; the side walls of the feed pipe and the discharge pipe extend to positions below the biogas slurry liquid surface of a circular fermentation pipeline; at least one gas baffle plate is arranged in the circular fermentation pipeline; a fermentation zone is formed between adjacent gas baffle plates, an independent gas guide pipe is arranged on the top of the fermentation zone, and a valve is arranged on the gas guide pipe; the fermentation system also comprises a bacterium distributing device which comprises a drain pipe, a bacterium distributing pipeline and bacterium distributing holes; the drain pipe is connected with the water pressure chamber; the bacterium distributing pipeline is ring-shaped, is fixed on the inner side wall of the circular fermentation pipeline, and is matched with the shape of the circular fermentation pipeline; and multiple bacterium distributing holes penetrating in the vertical direction are formed in the bacterium distributing pipeline.

Description

technical field [0001] The invention relates to a novel energy 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 ...

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.
