Technical Field

[0001] The utility model relates to the field of biogas tank devices, in particular to a biogas tank provided with a pressure relief device. Background Art

[0002] A biogas tank is a device used to store and process biogas, usually made of materials such as steel, concrete or plastic. Its main function is to collect, store and utilize biogas to meet the energy needs of households or industries. Biogas tanks are usually used in rural areas or farms.

[0003] Biogas is a renewable energy source produced by the fermentation of organic matter under anaerobic conditions. In the biogas tank, organic matter is decomposed to produce biogas. This will cause the gas inside the biogas tank to continue to increase during the process of decomposing organic matter to produce biogas. The pressure inside the biogas tank will continue to rise. When it reaches a certain threshold, if the pressure is not released in time, it may cause the tank to rupture or explode.
