Dragon type super-effective biogas fermentation system

Abstract

The invention discloses a dragon type super-effective biogas fermentation system. The dragon type super-effective biogas fermentation system comprises a feeding pipe, a discharge pipe and a U-shaped fermentation pipeline, the U-shaped fermentation pipeline is arranged horizontally, the feeding pipe and discharge pipe are vertically connected with two ends of the U-shaped fermentation pipeline, the upper part of the U-shaped fermentation pipeline is provided with a water pressure room, a water drain hole of the feeding pipe is formed in the joint between the water pressure room and the feeding pipe, a water drain hole of the discharge pipe is formed in the joint between the water pressure room and the discharge pipe, a feeding pipe gas baffle plate is arranged at the joint between the U-shaped fermentation pipeline and the feeding pipe, a discharge pipe gas baffle plate is arranged at the joint between the U-shaped fermentation pipeline and the discharge pipe, at least one gas baffle plate is arranged between the discharge pipe gas baffle plate and the feeding pipe gas baffle plate, a fermentation zone is formed between the feeding / discharge pipe and the adjacent gas baffle plate or between the adjacent gas baffle plates, and an independent gas gathering pipe is arranged at the top of each fermentation zone; the top of each fermentation zone is connected with the independent gas gathering pipe, and the gas gathering pipe is provided with a valve. By means of the U-shaped passage type fermentation device, the fermentation route is long, biogas slurry completely flows in the system under the control of water pressure difference and a check valve, the strain is driven to distribute uniformly, the crusting phenomenon is effectively avoided, and the gas productivity is high; the dragon type super-effective biogas fermentation system is suitable for scale production.

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...
