Embodiment Construction

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] Such as figure 1 As shown, the high-efficiency biogas digester with hydraulic horseshoe-shaped biogas slurry circulation and convection is mainly composed of a feed pipe 10, a discharge pipe 20, a fermentation pipe 30, and a water pressure room 40. The fermentation pipe 30 is a U-shaped fermentation pipe. The cross-sectional shape of the fermentation pipeline can be a geometric shape such as a prototype, a rectangle, and an ellipse. The U-shaped fermentat...

Abstract

The invention discloses a method for producing biogas in a water-pressure type horseshoe-shaped efficient biogas tank with biogas slurry circulative convection. The method comprises the following steps: pouring fermentation raw materials into a U-shaped fermentation pipeline through a discharge tube and fermenting in the U-shaped fermentation pipeline to produce biogas; and gathering the biogas to a fermentation region which is formed between the side wall of a charge / discharge tube and an adjacent gas baffle plate or adjacent gas baffle plates, introducing the biogas into a space in the fermentation region and extruding the biogas slurry in the fermentation region to form convection, so as to enable the biogas slurry exhausted out of the fermentation pipeline to flow to the charge tube, the discharge tube and a bacteria distributing device, and flow into a water pressure room through a water outlet tube of the discharge tube.

Description

technical field [0001] The invention relates to an anaerobic fermentation device, in particular to a biogas fermentation system. Background technique [0002] The working principle of the traditional biogas digester is that when biogas is generated in the pond, the biogas in the gas storage room increases continuously, and the pressure continues to increase, forcing the liquid level in the main pool to drop, and a part of the material liquid is squeezed out into the hydraulic room. When people turn on the stove, the pressure in the biogas digester gradually drops, and the feed liquid in the hydraulic chamber continuously flows back to the main pond. In this way, gas is produced and used continuously, so that the pressure in the fermentation room and the discharge room is always maintained in a state of pressure balance. [0003] Traditional biogas digesters have short fermentation routes, poor fluidity of biogas slurry, and uneven distribution of bacteria, resulting in a dec...
