Abstract

The invention discloses a ground methane tank capable of regulating methane pressure. The ground methane tank comprises a methane storage tank (1) and a fermenting tank (6) with a feed inlet (2), a feed outlet (3), a methane outlet (4) and a water outlet (5). The methane storage tank (1) and the fermenting tank (6) compose a split type structure and are communicated with each other by a methane pipe. An upper end of the methane storage tank (1) is an exhaust opening (11). A lower end of the methane storage tank (1) is arranged in a pool (8). The bottom of the methane storage tank (1) is communicated with the pool (8). The invention also discloses a manufacturing method of the ground methane tank capable of regulating methane pressure. The ground methane tank capable of regulating methane pressure adopts the split type structure of the methane storage tank (1) and the fermenting tank (6) and can regulate methane pressure in the methane storage tank (1) to maintain throughout the balance between the methane pressure and the atmospheric pressure. The ground methane tank capable of regulating methane pressure can be formed directly from flexible materials through curling and thus overcoming volume limitation. The ground methane tank capable of regulating methane pressure is suitable for large-scale production and popularization, has a simple structure, is beneficial for manufacture, and is convenient for use.

Description

technical field

[0001] The invention belongs to the field of biogas production, and in particular relates to an above-ground biogas tank with adjustable biogas pressure and a manufacturing method of the above-ground biogas tank. Background technique

[0002] Closed biogas digesters are now commonly used in the market to ferment organic matter into biogas, which has the advantage of cutting off the transmission of feces to transmit intestinal infectious diseases, parasitic diseases or other diseases, and reducing and controlling the pollution of the environment caused by the random discharge of feces. , is a comprehensive construction of energy, sanitation and fertilizer. At the same time, biogas slurry and biogas residue can be used for family breeding and fertilization.

[0003] However, this sealed biogas digester usually adopts the integrated structure of the fermentation tank and the gas storage room, that is, the fermentation tank and the gas storage room together form ...
