Super-efficient biogas fermentation system having unidirectional circular flowing function

Abstract

The invention discloses a super-efficient biogas fermentation system having a unidirectional circular flowing function. The super-efficient biogas fermentation system comprises a fermentation pool, partition boards, a water drainage pipe, a water pressure chamber and gas storage plates, wherein the fermentation pool is internally provided with sliding chutes matched with the partition boards; the partition boards are arranged in the fermentation pool and are used for partitioning the fermentation pool into a plurality of fermentation sub-pools; each partition board is provided with a water drainage hole communicated with the adjacent fermentation sub-pool; the fermentation pool is connected with the water pressure chamber through the water drainage pipe. Fermentation raw materials are uniformly distributed by means of reciprocating swing of pull rods, a pipeline is dredged by pulling the pull rods, the fermentation sub-pools having low fermentation efficiency are taken as auxiliary water pressure chambers, and in addition, self-cyclic flowing of the biogas slurry can be facilitated.

Description

technical field [0001] The invention relates to a biogas fermentation system. Background technique [0002] The hydraulic pipe-type biogas digester increases the fermentation rate and gas production by flowing the fermentation raw materials in the pipe, but it also has disadvantages: 1. The fermentation raw materials are easy to accumulate in the pipe, especially when straw is used as the fermentation raw material, which is very easy to If it is blocked at the feed end or discharge end, it can be dredged with a stick. If it is blocked deep in the pipeline, it will not be able to be cleaned, and the fermentation pipeline must be disassembled and cleaned; 2. Fermentation of pipeline biogas digesters The fluidity of the raw materials flowing in the pipeline is poor, especially when the straw is used as the fermentation raw material, the straw has poor fluidity, which is also easy to cause blockage, and affects the fermentation efficiency and the output. [0003] The breeding d...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is that the blockage of the existing pipe-type biogas digesters is difficult to deal with, and the large-scale pond culture causes the problem of lack of oxygen in the fish fry under the condition of poor power supply
