Ultra-efficient methane generation system with curved pneumatic extrusion biogas slurry flow and agitation

Abstract

The invention discloses a bend type pneumatic extrusion biogas fluid stirred flow super efficient methane generation system. The bend type pneumatic extrusion biogas fluid stirred flow super efficient methane generation system comprises a feed pipe, a discharge pipe and a U-shaped fermentation pipeline, the U-shaped fermentation pipeline is horizontally placed, the feed pipe and the discharge pipe are vertically connected with two end sides of the U-shaped fermentation pipeline, a hydraulic pressure room is located at the upper part of the U-shaped fermentation pipeline, the connection part between the hydraulic pressure room and the feed pipe is the feed pipe drain hole, the connection part between the hydraulic pressure room and the discharge pipe is the discharge pipe drain hole, the connection part between the U-shaped fermentation pipeline and the feed pipe is provided with a feed pipe gas baffle plate, the connection part between the U-shaped fermentation pipeline and the discharge pipe is provided with a discharge pipe gas baffle plate, at least one gas baffle plate is formed between the discharge pipe gas baffle plate and the feed pipe gas baffle plate, a fermentation region is formed between the feed pipe / discharge pipe and the adjacent gas baffle plate or between the adjacent gas baffle plates, an independent gas collecting pipe is arranged at the top of each fermentation region; the top of each fermentation region is connected with the independent gas collecting pipe and the independent gas collecting pipe is provided with a valve body; the fermentation line is long by adopting the U-shaped channel-type fermentation device, the biogas fluid can flow in the system for driving the bacteria to be evenly distributed through the control of the water pressure difference and the one-way valve, the crusting phenomenon can be effectively prevented and the gas yield is high.

Description

technical field [0001] The invention relates to the technical field of methane, in particular to a methane fermentation system. Background technique [0002] According to statistics, the current problem of methane in our country has reached about 3 million. The existing problems are: 1. Unreasonable materials used, resulting in serious air and water leakage in the pool body; 2. The mechanical performance of the methane pool is not good, reducing methane The structural strength of the pool causes wide structural cracks inside the pool body; 3. The connection between the inlet / outlet pipe and the pool body is bent, cracked, or even broken, and the shearing causes serious water and air leakage in the methane pool; 4. , The fermentation route of the methane pool is short, the efficiency of gas production is low, it is easy to crust, it is difficult to clean, and a large number of waste pools are generated. Contents of the invention [0003] The technical problem to be solved ...

AI Technical Summary

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the fermentation route in the methane fermentation system is short, the self-circulation effect of the biogas slurry is poor, and the uneven distribution of bacteria in the biogas slurry affects the gas production rate
