The double membrane gas holder mainly consists of bottom membrane, inner membrane, outer membrane, constant pressure control cabinet, protector, and some control equipment and auxiliary materials. The inner membrane of the double membrane gas holder is designed and made into a spherical cross-section connected to the bottom membrane or fermentation tank opening, forming a completely enclosed space for storing various applicable gases. So what are the installation advantages of double membrane gas cabinets? Below is a brief introduction for everyone:
The weight of a double membrane gas holder is one tenth of that of a traditional biogas holder, which saves on its production, transportation, installation, foundation, and footprint, as well as the cost of gas holder foundation and reactor top cover. It also saves on construction time and material costs.
1. Anti corrosion of double film gas holder membrane material
The inner membrane, outer membrane, and bottom membrane are all made of anti-corrosion film materials. Many people believe that the outer membrane will not come into contact with stored gases, so there is no need to use anti-corrosion film materials. In fact, the outer film may also be in a corrosive environment. In order to be safe, it is recommended to use anti-corrosion film materials for the outer film.
2. Welding process of double membrane gas holder
Ordinary welding methods can cause significant gas penetration, and the deformation and penetration caused by stress are even more severe. The inner membrane weld seam adopts patented welding technology, which has been treated multiple times to prevent gas penetration.
3. Triple protection function of double membrane gas holder
Another reason for the leakage is overpressure. We use electromagnetic pressure control combined with backup physical protection devices to increase the pressure of the cabinet. And taking into full consideration the fact that the inner membrane, as an isolation layer, cannot withstand pressure, a pressure balance technique is adopted to keep the inner membrane within the pressure range, making it less prone to leakage without overpressure.
4. A Reliable Control System for Double Membrane Gas Cabinets
Adopting a dual control system with dual fans and dual control. More accurate, more convenient to operate, equipped with carefully edited control programs, equipped with a new WGY type endometrial height detector, and equipped with dual LCD touch screens.
