Method for producing biogas by Panlong ultra-high-efficiency biogas fermentation system

Abstract

The invention discloses a biogas production method for a dragon type super-effective biogas fermentation system. The biogas production method for the dragon type super-effective biogas fermentation system includes steps that fermentation raw material is poured into a fermentation pipeline from a feed pipe, the fermentation raw material ferments in the fermentation pipeline to generate biogas, biogas is accumulated in fermentation zones formed between the feed / discharge pipe and adjacent gas baffle plate or between adjacent gas baffle plates, the biogas takes up the space in the fermentation zones and extrudes biogas slurry to generate convection and flow to the feed pipe and discharge pipe, and the biogas slurry in the fermentation pipeline inflows to a water pressure room in one direction through a water drain hole of the discharge pipe along with the rising of the biogas slurry surfaces in the feeding pipe and discharge pipe; the biogas in any one of the fermentation zones is used to reduce the biogas pressure in the fermentation zone, the biogas slurry in the adjacent fermentation zones flows to the fermentation zone, and the biogas slurry stored in the water pressure room returns to the fermentation pipeline in one direction through a water drain hole of the feed pipe to complement the reduced biogas space so as to finish circular biogas slurry flow.

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...
