Problems solved by technology

[0002] Most of the existing biogas digesters are integrally closed biogas digesters. The materials are placed in a sealed biogas digester for fermentation to produce gas. The amount of gas produced will decrease with the consumption of materials, and then the pressure in the biogas digester will decrease, that is, biogas The pressure of the biogas in the pool is unstable, which causes the pressure to be unstable when the user burns, and the flame suddenly grows and shrinks; if the biogas in the biogas pool is not used, the pressure in the biogas pool will increase, which is prone to explosion, and fire may cause life-threatening

Embodiment

[0020] figure 1 A schematic structural view of the constant pressure biogas digester of the present invention is shown. As can be seen from the figure, a constant pressure biogas digester includes: a biogas bottom pond 1 with an upper opening and a bottomless biogas pond cover covered on the biogas bottom pond 1 2. The bottomless biogas tank cover 2 is slightly smaller than the biogas bottom tank 1. The bottomless biogas tank cover 2 can freely move up and down according to the amount of biogas in the biogas tank. The bottomless biogas tank cover 2 is set There are excrement outlet 3, catheter 4 and airway 5. The fermented material is placed in the space formed by the biogas bottom tank 1 and the bottomless biogas tank cover 2, and the biogas generated after the fermentation of the fermented material is directly stored in the bottomless biogas tank cover 2, and the pressure of the generated biogas can make the bottomless biogas tank cover 2 Jacking up, the lifting of the bott...

Abstract

The invention discloses a constant pressure methane tank which comprises a methane bottom tank with an opening at the upper part, and a bottomless methane tank cover covering the methane bottom tank, wherein the bottomless methane tank cover is slightly smaller than the methane bottom tank; the bottomless methane tank cover can move up and down freely according to the amount of methane in the methane tank; and feces outlets, a conduit and a gas-guide tube are formed in and arranged on the bottomless methane tank cover. The bottomless methane tank cover of the methane tank can move up and down freely according to the gas yield, so that the pressure in the methane tank is constant, and the problem of pressure change in the existing methane tank is solved.

Description

technical field [0001] The invention relates to a biogas fermentation device, in particular to a constant-pressure biogas pond. Background technique [0002] Most of the existing biogas digesters are integrally closed biogas digesters. The materials are placed in a sealed biogas digester for fermentation to produce gas. The amount of gas produced will decrease with the consumption of materials, and then the pressure in the biogas digester will decrease, that is, biogas The pressure of the biogas in the pool is unstable, which causes the pressure to be unstable when the user burns, and the flame suddenly grows and shrinks; if the biogas in the biogas tank is not used, the pressure in the biogas tank will increase, which is prone to explosion, and fire may cause life-threatening. In addition, the sealed biogas digester needs to replace the materials regularly, and the biogas can only be used after 3 to 5 days after replacing the materials. Contents of the invention [0003]...
