How does a Double Membrane Bio Gas Holder work?

A Double Membrane Bio Gas HolderDouble Membrane Bio Gas Holder is an important component of many anaerobic digestion systems. This technology is used to capture and store biogas produced by organic waste in order to generate renewable energy. Here’s how a Double Membrane Bio Gas Holder works:

Step 1: Biogas production.

The process begins with the production of biogas. Organic waste is fed into an anaerobic digester, where it is broken down by microorganisms in the absence of oxygen. This produces a mixture of gases, mostly methane (CH4) and carbon dioxide (CO2), which is known as biogas.

Step 2: Biogas collection.

The biogas is then collected from the digester and piped into the Double Membrane Bio Gas Holder. This consists of two flexible membranes, one inside the other, that are sealed at the top and bottom. The space between the two membranes is inflated with air to create a buffer zone.

Step 3: Biogas storage.

As the biogas enters the space between the membranes, it displaces the air, causing the outer membrane to expand. This creates a space for the biogas to be stored. The inner membrane is attached to the biogas inlet at the bottom of the holder, while the outer membrane is attached to the frame of the holder.

Step 4: Biogas usage.

The stored biogas can then be used to generate renewable energy, such as electricity or heat. The biogas is piped out of the Double Membrane Bio Gas Holder to a gas engine or boiler, which converts the energy in the biogas into usable forms of energy.

Step 5: Biogas replenishment.

As biogas is used, the pressure in the Double Membrane Bio Gas Holder decreases, causing the outer membrane to contract. This draws in air from the buffer zone, which allows the holder to maintain a constant pressure. The inner membrane also moves down to keep a seal over the biogas inlet.

Step 6: Maintenance.

The Double Membrane Bio Gas Holder requires regular maintenance to ensure it remains functional and safe. The membranes must be inspected and repaired or replaced as needed to prevent leaks or damage. The frame and support structure must also be checked to ensure they are secure and stable.

In summary, a Double Membrane Bio Gas Holder works by using flexible membranes to capture and store biogas produced by organic waste. The biogas can then be used to generate renewable energy, while the holder maintains a constant pressure through the use of a buffer zone and regular maintenance.
