Curved ultra-long fermentation path methane generation device

Abstract

The invention discloses a curved ultra-long fermentation path methane generation device. The curved ultra-long fermentation path methane generation device comprises a feeding pipe, a discharging pipe and a U-shaped fermentation pipeline, wherein the U-shaped fermentation pipeline is horizontally arranged, the feeding pipe and the discharging pipe are vertically connected with two end sides of the U-shaped fermentation pipeline, a water pressure room is arranged at the upper part of the U-shaped fermentation pipeline, a drainage hole of the feeding pipe is formed at the joint of the water pressure room and the feeding pipe, the drainage hole of the discharging pipe is formed at the joint of the water pressure room and the discharging pipe, a gas blocking plate of the feeding pipe is arranged at the joint of the U-shaped fermentation pipeline and the feeding pipe, a gas blocking plate of the discharging pipe is arranged at the joint of the U-shaped fermentation pipeline and the discharging pipe, at least one gas blocking plate is further arranged between the gas blocking plate of the discharging pipe and the gas blocking plate of the feeding pipe, a fermentation area is formed between the feeding/discharging pipe and the adjacent gas blocking plate or between the adjacent gas blocking plates, and an independent gas collection pipe is arranged at the top of each fermentation area; the top of each fermentation area is connected with the independent gas collection pipe, and a valve body is arranged on the gas collection pipe; a U-shaped channel type fermentation device is adopted, so that a fermentation route is long; and the water pressure difference and the control of a single-way valve are used to realize full flow of biogas slurry in the system and drive the uniform distribution of strains, thereby effectively preventing encrustation, realizing high gas production rate; therefore the device is suitable for large-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...
