Method for generating methane in methane generation system hydraulically and pneumatically promoting bacteria distribution

Abstract

The invention discloses a method for generating methane in a methane generation system hydraulically and pneumatically promoting bacteria distribution. The method includes the steps: pouring fermentation raw materials from a feeding pipe and fermenting the raw materials in a fermentation pipeline to generate the methane; using the methane stored in an optional fermentation area. The methane is gathered in fermentation areas formed among the feeding / discharging pipe and adjacent gas baffle plates or between the adjacent gas baffle plates, occupies space in the fermentation areas, squeezes biogas to generate convection and the biogas flows towards the feeding pipe, the discharging pipe and a bacteria distribution device, and the biogas slurry in the fermentation pipeline unidirectionally flows into a water pressure space through a drain hole of the discharging pipe along with rise of the liquid level of the biogas slurry in the feeding pipe, the discharging pipe and the bacteria distribution device. The pressure of the methane stored in the optional fermentation area is reduced, the biogas slurry in an adjacent fermentation area flows towards the optional fermentation area, and the biogas slurry stored in the water pressure space unidirectionally flows back into the fermentation pipeline through a drain hole of the feeding pipe and a drain pipe of the bacteria distribution device to supplement reduced methane space, so that circulating flow of the biogas slurry is finished.

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.
