Ultra-high-efficiency methane generation system of hydraulic biogas slurry bending flow stirring

Abstract

A hydraulic biogas slurry curved flow stirring super-efficient methane generation system comprises a feeding pipe, a discharging pipe and a U-shaped fermentation pipeline. The U-shaped fermentation pipeline is horizontally placed, the feeding pipe and the discharging pipe are vertically connected with two end sides of the U-shaped fermentation pipeline, a water pressure space is formed in the upper portion of the U-shaped fermentation pipeline, a feeding pipe drain hole is formed in the joint of the water pressure space and the feeding pipe, a discharging pipe drain hole is formed in the joint of the water pressure space and the discharging pipe, a feeding pipe gas baffle plate is arranged at the joint of the U-shaped fermentation pipeline and the feeding pipe, a discharging pipe gas baffle plate is arranged at the joint of the U-shaped fermentation pipeline and the discharging pipe, at least one gas baffle plate is arranged between the discharging pipe gas baffle plate and the feeding pipe gas baffle plate, a fermentation area is formed among the feeding / discharging pipe and the adjacent gas baffle plates or between the adjacent gas baffle plates, an independent gas collecting pipe is arranged at the top of each fermentation area, the top of each fermentation area is connected with the independent gas collecting pipe, and a valve is arranged on each gas collecting pipe. A U-shaped channel-type fermentation device is used, a fermentation path is long, biogas slurry sufficiently flows in the system by control of water pressure difference and one-way valves, bacteria are driven to be uniformly distributed, crusting is effectively prevented, and gas generating rate 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
