Shandong Yantai Pharmaceutical Factory sewage 400m³ integrated gas holder

The double membrane gas holder tank roof combines fermentation gas storage into a single unit.The bottom portion consists of a digester tank body,while the upper portion is a 3/4 spherical gas storage structure made of special polyester material,This design greatly conserves ground space.

The outer membrane of the mounted double membrane gas holder is sealed and connected to the tank opening edge of the fermentation tank independently,while the inner membrane is used for storing generated biogas.They are both anchored to the embedded fasteners in the foundation and sealed.The inner membrane stores the produced biogas and releases it as needed under the control of the outer membrane's pressure. The safety protection system is designed to safeguard the Haiyue double membrane gas holder by preventing excessive pressure in the inner or outer membrane due to system malfunctions,ensuring controlled discharge. 

The control cabinet system primarily detects gas holder pressure and inner membrane capacity, allowing for pressure relief protection and control of gas intake as per the design requirements. The role of the outer membrane of the biogas holder is to create a pressure-regulating space,providing constant external pressure to the inner membrane to maintain a consistent biogas output. Simultaneously, the outer membrane offers protection to the inner membrane.
