Double Membrane Gas Holder/Gas storage Cabinet is a durable air supported structure specifically designed for the purpose of biogas storage.
It can be used as an independent gas storage structure, or be installed as part of the anaerobic digestion system in a wastewater treatment plant, agricultural digestion schemes, landfill sites and combined heat-and-power plants that use digested organic materials to generate biogas as an energy source.
Scope of application
It apples to a variety of neutral gases such as methane, air, carbon dioxide, oxygen and so on.
Fundamental consist of this system
1. Main material: Biogas special-used membrane material is made of highly tear-resistant and anti-corrosion polyester fabrics.
2. Gas in and out system: standard pipeline
3. Gas booster fan
4. Observation window
5. Auto-control system
6. Alarming system
7. Display system
8. Safety protector: safe by water seal and electric decompression
9. System lifespan is at least 25 years
Technical parameters of Biogas holder
Gasholder Size: 50 ~ 5000M3 customized
All the membranes of gas holder together form two spaces.The inner membrane serves as storage space of various gases.The intermediary space between outer membrane and inner membrane is for pressure regulating. A permanently functioning air blower feeds air into the intermediary space according to inner membrane pressure which shows through the signal on auto-control panel.
Why choose independent double membrane gas storage system? Compared with the traditional biogas storage(wet-type, dry-type), membrane storage system get the advantages as follows: 1.Biogas can be 100% used, the inner biogas can be totally squeezed out which is hardly to achieve by the traditional one. 2.In light weight:It weighs only a small percentage than the traditional one. This does great good for make, transportation, installation, etc. And saving a lot of construction time and material cost. 3.No need to maintain for long: For the membrane field is made of super anti-corrosion material, and can last more than 25 years in biogas circumstance. Meanwhile, it is well welded by hot-melted material, so we don't have to do the regular maintain when use membrane storage. 4.It saves much time and labor: For it is small and light, also the membrane field has been well-shaped in factory, so the on-site installation will just cost 1-2days. 5. Saving money:From the mentioned above, we can see that the total cost is lower than that of the traditional one. 6.Anti-freezing: For there is no water in the inner structure, there is no need to worry about the frozen problem in the cold area. 7. Keep warm: As we know, air is perfect medium to keep warm, so the air between the two layer membrane make the system warmer than the traditional one. 8. Artistic: the main color of the membrane is grey white, so it can easily be matched. Meanwhile, the whole structure is designed to be spheroidal, and this araise the sense of beauty. 9. Comparatively safe when the accident happens: Anyway, biogas is flammable gas, if by any chance explosion happens, it will not produce so much injury pieces as other hard material made storage. 10. Easily remove: if customers need to remove the system, it can be easily achieved. There is no need to worry about the by-way produced useless and difficult transportation.From this point, it is better than any kind of traditional design. 11.Fire protection: The material of membrane field is non-flammable, the fire protection grade reach the Euro-standard B.
