Protective system for methane tank

Abstract

The invention discloses a protective system for a methane tank, and belongs to the field of the building of methane tanks. The protective system consists of a methane tank, a material inlet and a protective system, and is characterized in that: a gas collection opening is formed on the upper part of the methane tank and is connected with a gas collection pipe, and the gas collection pipe is connected with a gas tank by a gas extracting pump; the gas extracting pump and the gas tank are controlled by a valve; the valve is also connected with the gas tank; a pressure gauge is arranged on the gas tank; a filter opening of the gas collection pipe is formed at the bottom of a water tank of the protective system; one end of a gas outlet pipe is exposed from the water surface of the water tank, and the other end of the gas outlet pipe extends to users for gas utilization; and a lower sealing cover is arranged at the bottom of the water tank. In the protective system, the explosion of methane in a gas storage tank and a pipeline due to backfire is prevented, and the problem of backfire is solved effectively by taking water as an isolation means. The purity of the methane can be improved, combustible gas contains a certain quantity of solid granules, and part of impurities can be filtered by water filtration conveniently, so the cost is low.

Description

technical field [0001] The invention relates to the field of biogas pit construction, in particular to a biogas pit protection system. Background technique [0002] Rural biogas construction is a livelihood project and an ecological project that optimizes the living environment and promotes the transformation of rural energy consumption structure. In recent years, under the vigorous promotion of the government, it has developed rapidly. However, while the majority of farmers are enjoying the convenience brought by biogas, many farmers are not vigilant and have low safety awareness due to lack of basic knowledge of safe use and maintenance. , Lack of corresponding technology and equipment, blind maintenance or slag removal, leading to major accidents of farmers dying in biogas digesters. Biogas is a flammable, explosive, and toxic dangerous gas. There are many dangers lurking in its production and use. A little improper operation can easily lead to accidents. During operatio...
