The floor - type double - membrane gas storage tank has a shape of a sphere or hemisphere with a volume of 314. It is fixed on a cement foundation by steel rails. The main body is made of environmentally - friendly special composite materials imported from Gerui, which is corrosion - resistant. The gas storage tank consists of an outer membrane, an inner membrane, a bottom membrane, a sealing system, a film - blowing fan, a pressure protector, an intelligent control cabinet and other accessories.
The outer membrane forms a spherical shape and plays a protective role. Even in strong winds and thunderstorm weather, the outer membrane can continuously bear pressure and maintain stiffness. The inner membrane and the bottom membrane enclose an inner cavity to store biogas. The film - blowing fan automatically adjusts the gas inflow and outflow to maintain the stability of the gas tank pressure and can also protect the outer membrane under severe weather conditions. The bottom membrane is laid flat on the civil engineering foundation, so that the biogas is completely sealed between the inner membrane and the bottom membrane.
