Abstract

The invention discloses a method for producing biogas by a biogas slurry reflux stirring device of an auger type biogas generation system. The method comprises the steps of pouring fermentation raw materials from a feeding pipe, fermenting in a fermentation pipeline to produce biogas, respectively gathering the biogas in fermentation areas formed between the feeding pipe / discharging pipe and adjacent gas blocking plates or between the adjacent gas blocking plates, enabling the biogas to occupy the space in the fermentation area, extruding biogas slurry to realize convection, and enabling the biogas slurry to flow to the feeding pipe, the discharging pipe and a bacteria distribution device, wherein the biogas slurry in the fermentation pipe flows into a water pressure room through a drainage hole of the feeding pipe, the drainage hole of the discharging pipe and a drainage pipe of the bacteria distribution device as the liquid level of the biogas slurry in the feeding pipe, the discharging pipe and the bacteria distribution device rises; and using the biogas stored in any one fermentation area, wherein the gas pressure of the biogas stored in the fermentation area is reduced, the biogas slurry in the adjacent fermentation area flows into the fermentation area, and the biogas slurry stored in the water pressure room flows back into the fermentation pipeline through the drainage hole of the feeding pipe, the drainage hole of the discharging pipe and the drainage pipe of the bacteria distribution device to supplement the reduced biogas space, thereby completing the circulating flow of the biogas slurry.

Description

technical field [0001] The invention relates to the technical field of biogas, in particular to a biogas fermentation system. Background technique [0002] According to statistics, there are currently about 3 million biogas problems in my country. The problems are: 1. Unreasonable materials used, causing serious air and water leakage in the pool; 2. Poor mechanical performance of biogas digesters, reducing biogas The structural strength of the pool causes wide structural stress cracks inside the pool body; 3. The connection between the inlet / outlet pipe and the pool body is bent, sheared or even broken, and the shearing causes serious water and air leakage in the biogas tank; 4. 1. The fermentation route of the biogas digester 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 ponds are generated. Contents of the invention [0003] The technical problem to be solved by the invention is that the ferme...
