Dual Membrane Gas Domes on Digester
Brief introduction of dual membrane gas domes on digester
The versatile ¼-spherical to ¾-spherical gas storage solution which is installed directly on top of steel or concrete tanks, complementing the functionality of the tank.
Dual membrane gas domes on digester consist of a formative outer membrane and of an inner membrane that hermetically seals the fermentation space (gas-tight seal). The pressure generated inside the intermediary space by a permanently functioning supporting air blower keeps up the outer membrane, such that the gas domes withstands all kinds of external loads. Both membranes are anchored to the crown or to the outer wall of the steel or concrete tank using clamping rails with a positive and non-positive fitting. The positive fitting is secured by a rope welded into the outer rim of the membrane.
A substructure prevents the inner membrane from plunging into the substrate and from being destroyed by agitators. The braces and central pole are designed to assume the required loads. We provide you with static calculations including proof upon request.
Application of dual membrane gas domes on digester
Livestock farm, Brewery wastewater treatment, Beer wastewater treatment plant, the paper mill wastewater treatment, urban sewage treatment, garbage disposal, food waste treatment, , Food wastewater treatment, crops’ waste treatment , food factory sewage treatment, etc.
Advantages of dual membrane gas domes on digester
Compared with Chinese traditional biogas storage (wet-type, dry-type), membrane storage system has the advantage as follows:
Biogas can be 100% used: the inner biogas can be totally squeezed out which is hardly to achieve by the traditional one.
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.
No need to maintain for long time: For the membrane is made of the super anti-corrosion material and can last more than 15 years in the biogas circumstance. Meanwhile, it is well welded by high frequency, so we do not have to do regular maintain when use membrane storage.
It saves much time and labor: For it is small and light, also the membrane has been well-shaped in factory, so the on-site installation will just cost only a few days.
Saving money: From the mentioned above, we can know that the total cost is lower than that of the traditional one.
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.
Keep warm: As we know, air is the perfect medium to keep warm. So the air between two-layer membranes makes the system warmer than the traditional one.
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 arise the sense of beauty.
Comparatively safe when accident happens: Anyway, biogas is flammable gases, if by any chance explosion happens, it will not produce so much injury pieces as other hard material made storage.
Easily repair: If unforeseeable things happened, most of the maintenance can be easily done at present. For example, when gas leaking, it only need a small patch.
Easily remove: If customer needs 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.
Fire protection: The material of membrane field is non-flammable, the fire protection grade reaches the Euro-standard B.
