Problems solved by technology

[0003] The main component of biogas is methane. Biogas is composed of about 50% to 80% of methane, 20% to 40% of carbon dioxide, and about 1% to 3% of hydrogen sulfide and other gases. Since hydrogen sulfide is a toxic gas, In daily life, it is necessary to remove hydrogen sulfide gas in biogas, that is, to perform desulfurization treatment. In addition, carbon dioxide needs to be removed to improve the purity of methane before it can be used normally. The existing equipment for removing hydrogen sulfide in biogas is Desulfurization tower and desulfurizer, the desulfurizer is equipped with iron oxide particles in the container, and the iron oxide particles are used to desulfurize the hydrogen sulfide gas in the biogas, but the use of the desulfurization tower or desulfurizer still has the high cost of the device itself, Complicated installation structure and other deficiencies
[0004] In addition, the biogas formed after reaction and fermentation in the main pond can be transported to the biogas storage tank in a concentrated manner. Under normal circumstances, it can still meet the needs of people with a large amount of gas for use in case of emergency, and also saves fuel energy. However, the existing gas storage tanks usually use steel tanks and membrane gas storage tanks, and steel tanks are very heavy. It is not conducive to transportation and installation, and the pure steel structure is easy to rust and rot, the service life is short, and the workload of anti-corrosion and inspection is large. The problem of high operating costs and many additional equipment

Embodiment Construction

[0029] Below in conjunction with accompanying drawing and specific embodiment the present invention will be described in further detail:

[0030] like figure 1 , figure 2 Shown, a kind of biogas storage tank, comprises gas storage tank 18 and sludge tank 19, the top of gas storage tank 18 is provided with gas delivery pipe 20, and the side wall of sludge tank 19 is provided with water outlet 21, and sludge The other side wall of the pool 19 communicates with the gas storage tank 18, and the bottom of the gas storage tank 18 slopes downward toward the connection between the sludge tank 19 and the gas storage tank 18, and extends to the place where the outlet 21 of the sludge tank 19 is located. Side wall; the cross-section of the bottom of the gas storage tank 18 is a concave hemispherical shape; the gas storage tank 18 is in the shape of a trapezoid with a narrow top and a wide bottom. The inclination angle of the bottom surface of the gas storage cabinet 18 is 30 degrees, ...

Abstract

The invention discloses a methane storage cabinet and a methane tank containing the methane storage cabinet. The methane storage cabinet comprises a sludge tank and a gas storage cabinet communicated with the sludge tank, wherein the bottom of the gas storage cabinet inclines down to the place where the sludge tank is communicated with the gas storage cabinet and the bottom of the gas storage cabinet extends to a side wall where a water outlet hole of the sludge tank is located, the cross section of the bottom of the gas storage cabinet is an indent hemisphere. The methane tank containing the methane storage cabinet comprises a main tank and a hydraulic pressure room, wherein a dung inlet is formed in one side of the main tank, a dung outlet is formed between a fermentation tank and the hydraulic pressure room, and the dung outlet is formed in the other side wall of the fermentation tank; the upper edge of the dung inlet and the top of the dung outlet are arranged on the same horizontal line; the bottom of the fermentation tank inclines downwards from the side wall where the dung inlet is located to the hydraulic pressure room and extends to the side wall where an overflow hole of the hydraulic pressure room is located; and a dung drainage channel with the cross section in an indent hemisphere shape is formed in the bottom of the fermentation tank. The invention aims to provide a methane storage cabinet with a simple structure, low cost and long service life and a methane tank which is constant in methane pressure, convenient for deslagging and high in methane yield and hardly causes crusting.

Description

technical field [0001] The invention belongs to the technical field of biogas tanks, and in particular relates to a biogas storage tank and a biogas tank including the gas storage tank. Background technique [0002] With the improvement of living standards, the issue of energy conservation has gradually attracted people's attention. In recent years, biogas has gradually become popular in most rural areas of our country and has been recognized by people. At present, the country has formulated corresponding standards for the construction of biogas digesters used in rural areas. Hydraulic biogas digesters are the most popular household biogas digesters in my country. In terms of structure, they usually include biogas digesters with spherical arches and square arches. Biogas digesters, biogas digesters usually include a main pool and a water pressure room, the main pool and the water pressure room are connected, and the main pool is divided into a gas storage room and a fermenta...
