Innovative model of biogas storage promotes the use of double-membrane gas storage cabinets with lasting national subsidies

The innovative model of biogas storage promotes the use of double-membrane gas holders with long-lasting national subsidies. Double-membrane gas holders are a revolutionary technology in the field of biogas engineering: Compared with traditional steel structure gas holders, double-membrane gas holders are low-cost, quick to install, and do not require anti-corrosion. Maintenance has been widely used and developed. > The unique and novel appearance of Liyang's double-membrane gas holder has become the most beautiful scenery in environmental engineering!
Functional Description
Liyang double membrane gas storage cabinet is mainly composed of three parts: outer membrane, inner membrane and bottom membrane. The inflatable outer membrane forms a protective shell with a certain degree of rigidity. Even in extreme situations (such as storms), the outer membrane can continue to bear pressure to maintain static pressure balance. The inner membrane is used to store biogas and automatically shrinks and expands according to the amount of gas stored. The bottom membrane is flat. It is laid on the civil foundation so that the biogas is completely sealed in the storage space of the inner membrane and the bottom membrane.
Liyang's double-membrane gas storage tank comes with a set of overpressure protection devices to prevent overpressure in the gas tank in an emergency. Antifreeze can be added to the water seal to meet the needs of severe cold conditions.
The installation nodes between the membrane and the foundation of Liyang's double-membrane gas storage cabinet use special guide rails and bolts. The guide rails are made of stainless steel and are installed on-site using German Hilti expansion bolts. There is no need for pre-embedded pressure plates and the installation is quick.
The strength selection of the membrane material of Liyang double-membrane gas storage tank depends on the working pressure of the gas tank and the wind and snow load. The general range is from , (shaped membrane material) to , (shaped membrane material). The membrane material has antibacterial, anti-ultraviolet, self-cleaning properties, and remains inert to the main components of biogas (,,,). The membrane material is a fully imported biogas-specific membrane material: the sunlight fastness meets the grade 1 standard, the flame retardant performance meets the B design standard, the thermal expansion and contraction resistance meets the standard, the waterproofing meets the standard, and the ductility meets the standard.
Liyang double membrane gas holder control equipment
The fan is an important part of the double membrane gas holder. Special anti-corrosion and explosion-proof fans made of R material are selected to adapt to the harsh on-site environment and ensure the durability of the fan.
The system uses a pressure sensor to monitor the operating pressure of the gas cabinet and can switch to automatic operation (power saving mode). When the pressure is higher than the set value, the fan is turned off. When the pressure is lower than the set value, the fan is started.
Liyang's double-membrane gas storage tank storage monitoring device is an important part of the gas tank. The biogas storage capacity signal can be used for remote control of subsequent biogas user equipment. For example, when the counter reaches the % high level, the biogas torch will be automatically started.
The operating pressure signals, fan operating signals, fault alarm signals, etc. of Liyang's double-membrane gas storage cabinet can be collected through the on-site electric control cabinet and then uniformly output to the central control.
Jining Liyang Environmental Protection Equipment Manufacturing Co., Ltd. mainly sells products: solid-liquid separators, horizontal mixers, desulfurizers, vertical mixers, horizontal crushers, chicken manure dryers, trommel screens, submersible mixers, Water sealer, enamel fermentation tank, rotary cooler, municipal waste treatment system, disc coating machine, etc.
