Manure from farms, industrial waste, kitchen scraps, and some agricultural waste, after fermentation, produce a large amount of biogas. When the biogas output reaches a certain level and cannot be utilized, a Cubic Double-Membrane Gas Storage Tank is needed. The double-membrane tank is a container for storing gases, suitable for the storage of various neutral gases, such as biogas, air, carbon dioxide, oxygen, etc.

The cubical double-membrane gas cabinet, when installed as an integrated gas cabinet, is positioned above the reactor with the outer membrane providing structural rigidity. The inner membrane remains in pressure balance, exhibiting normal extension, and its service life is extended due to this pressure balance. The double-membrane gas cabinet is lightweight and easy to transport, with simple installation and maintenance. The outer membrane structure utilizes standard piping, and the double-membrane gas equipment injects atmosphere into the pressure-regulating layer, evenly balancing the pressure within the cabinet and ensuring the stability of the outer membrane's rigidity.
