Marsh gas storage tank with anti-backfire function

Abstract

The invention relates to a marsh gas storage tank with an anti-backfire function. The marsh gas storage tank comprises a tank body with an inner cavity. An air inlet pipe and an air outlet pipe communicating with the inner cavity of the tank body are arranged on the tank body. A desulfurization bed is arranged in the tank body. The inner cavity of the tank body is divided into an upper cavity and a lower cavity through the desulfurization bed. The air inlet pipe communicates with the lower cavity. The air outlet pipe communicates with the upper cavity. The tank wall of the tank body is a heat insulation tank wall provided with a cavity. A water inlet is formed in one side of the upper end of the tank wall, and a water outlet is formed in the other side of the upper end of the tank wall. The air outlet pipe is further connected with a fire barrier. The fire barrier comprises a fire barrier cavity and a fire retarding material arranged in the fire barrier cavity. An exhaust pipe is arranged on one side of the upper end of the fire barrier. The marsh gas storage tank has the advantages that toxic substances in marsh gas can be removed through the desulfurization bed in the tank body, and the application safety of the marsh gas is improved; and the temperature of the marsh gas can be stabilized at a certain value through the heat insulation tank wall of the tank body, and natural phenomena caused by the overheated marsh gas are avoided.

Description

technical field [0001] The invention relates to a gas storage tank, in particular to a methane gas storage tank with a backfire prevention function. Background technique [0002] Biogas is a combustible gas produced by microbial fermentation of organic matter in an anaerobic environment under certain temperature, humidity and pH conditions. In order to improve the living environment in rural areas and promote the development of ecological agriculture and animal husbandry, it is often A biogas digester for fermenting biogas is built together with toilets and pigpens. [0003] A biogas storage tank is a container that can store biogas, but when the existing biogas storage tanks are in use, it is easy to cause the gas storage tank to explode due to backfire caused by the combustion of biogas. Therefore, a new technical solution should be provided to solve the above problems. Contents of the invention [0004] The object of the present invention is to provide a biogas storag...
