Abstract

The invention discloses a gas storage device for a straw biogas digester. The gas storage device comprises a biogas digester positioned under the earth surface and a biogas chamber positioned under the earth surface; a casing of the biogas chamber is of a dual-layer structure including an outer layer membrane and an inner layer membrane; a heat insulating and pressure regulating chamber serving as a heat insulating layer and a pressure regulating cavity is arranged between the outer layer membrane and the inner layer membrane; an air inlet is formed in the heat insulating and pressure regulating chamber and connected with a blower outside the biogas chamber; a pressure controller is arranged in the heat insulating and pressure regulating chamber and connected with the blower for controlling; a steel wire protecting net is arranged on an outer layer of the outer layer membrane and comprises an upper annular weft net, a middle annular weft net and a lower annular weft net; the upper annular weft net is movably connected with the middle annular weft net by connecting steel bars; the middle annular weft net is movably connected with the lower annular weft net by the connecting steel bars.

Description

technical field [0001] The invention relates to the field of biogas preparation and storage, in particular to a gas storage device for a straw biogas digester. Background technique [0002] At present, ordinary biogas storage tanks have the following problems: 1. When the biogas residue is discharged or the water level drops, a certain negative pressure will be generated inside the gas storage tank, which will cause certain damage to the gas storage tank; 2. No heat preservation The temperature is low, and the biogas is produced by the activities of various anaerobic bacteria. The normal adaptation temperature of anaerobic bacteria is 8-70°C, and no biogas will be produced below 8°C. This is why biogas projects in northern my country cannot produce gas in winter. 3. When the biogas material is reduced or the water level is insufficient, the biogas pressure cannot be constant, especially the requirement of the biogas generator set for constant pressure; 4. When the slag is disc...
