Method for generating methane by biogas slurry turbulence promoting device of bended methanol generation system

Abstract

The invention relates to a method for generating methane by a biogas slurry turbulence promoting device of a bended methanol generation system. The method comprises the following steps: a fermenting raw material is poured from a feed pipe to a fermenting pipeline to be fermented to generate methane; methane is respectively gathered in fermenting regions formed between the feed / discharge pipe and adjacent gas baffle plates or between adjacent gas baffle plates; methane occupies the space in the fermenting region and extrudes biogas slurry to generate convection and flow to the feed pipe, the discharge pipe and a bacteria distributing device; along with elevation of the liquid level of the biogas slurry stored in the feed pipe, the discharge pipe and the bacteria distributing device, the biogas slurry in the fermenting pipeline firstly flows into a water pressure room through a drain hole of the discharge pipe, and when the liquid level of the biogas slurry stored in the water pressure room reaches the lowest position of a drain pipe of the bacteria distributing device, the biogas slurry flows into the water pressure room through the drain pipe of the bacteria distributing device; and when the air pressure of methane stored in any one fermenting region is reduced because methane is used, the biogas slurry in adjacent fermenting region flows to the fermenting region and the biogas slurry stored in the water pressure room flows back unidirectionally to the fermenting pipeline through the drain hole of the feed pipe and flows back to the fermenting pipeline through the drain hole of the discharge pipe and the drain pipe of the bacteria distributing device so as to compensate the methane space reduced in the fermenting region. Therefore, the biogas slurry flows circularly.

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.
