Discover the Advantages of the Double Membrane Biogas Balloon for Biogas Storage

Product Description

The double membrane biogas balloon represents an innovative category of gas storage equipment, distinguished by its numerous unique features and advantages. Below is a comprehensive description:

Structural Composition:

• Bottom Membrane: This component primarily functions as a foundational seal, achieving corrosion resistance and impermeability that traditional infrastructure cannot provide. It establishes a stable base seal for the entire gas storage tank, ensuring that no gas escapes from the bottom. In standalone ground-mounted double membrane biogas balloon, the bottom membrane is essential; however, it may not exist independently in integrated systems.
• Inner Membrane: Serving to isolate the stored gas from the pressure-regulating gas in the outer membrane, this element constitutes the core of gas storage. It exhibits excellent airtightness and corrosion resistance, guaranteeing that stored gases do not intermingle with external air or pressure-regulating gases while maintaining their purity and quality.
• Outer Membrane: The outer membrane creates a pressure-regulating chamber that enables consistent output from the inner membrane. Additionally, it provides protection for the inner membrane itself. Connected at its edges to either the inner membrane or fermenter outlet, this outer shell withstands environmental influences while safeguarding against damage to the inner membrane and ensuring constant internal pressure within the tank.
• Pressure Control Cabinet: Serving as the central control system for the dual membrane gas storage tank, it is capable of real-time monitoring and regulation of internal pressure. When there are fluctuations in the volume of stored gas, the pressure control cabinet automatically adjusts associated equipment to optimize the inflow and outflow of regulating air, thereby ensuring stable pressure within the tank.
• Safety Protection Devices: These devices are specifically designed to safeguard the gas storage tank during operation. For instance, if the internal pressure exceeds acceptable limits, the safety protection device will automatically engage and implement appropriate measures—such as venting excess gas or halting intake—to prevent potential damage from excessive pressure.
• Additional Control Equipment and Accessories: This category includes anti-explosion blower, piping systems, valves, sensors, etc. Collectively, these components function synergistically to ensure both optimal performance and safe storage of gas within the dual-membrane gas storage tank.

Working Principle:
 

The bottom membrane and the outer membrane collaboratively create a sealed gas storage chamber. When the volume of stored gas increases, the control system releases regulating air to free up a specific capacity, resulting in the outward expansion of the inner membrane to accommodate additional stored gas; conversely, when the gas volume within the inner membrane decreases, the control system injects regulating air to equilibrate pressure within the tank and maintain the rigidity of the outer membrane, thereby ensuring optimal operation of the gas storage unit. To prevent any mixing between stored gas and regulating air, effective isolation is achieved through the inner membrane.

Appearance and Fixed Method:

The Double Membrane Biogas Balloon for Biogas Storage typically features a 3/4 spherical design, secured to a concrete foundation using steel tracks. This structural configuration imparts enhanced stability and seismic resistance to the gas tank.

Main Technical Parameter

Advantages
 

• Safety and Reliability: The materials utilized in the double membrane biogas balloon exhibit resistance to biogas corrosion, ultraviolet radiation, and microbial degradation. Its service life typically ranges from 15 to 25 years or more, during which no anti-corrosion treatment is necessary. All metal connectors are constructed from stainless steel to withstand corrosive environments associated with gas storage tanks. Additionally, this system is equipped with a variety of safety protection devices, including overpressure safety valves and biogas leakage alarms, ensuring the safe operation of the gas storage tank.
• Environmental Friendliness: In comparison to wet gas storage tanks, double membrane gas storage tanks do not generate significant amounts of phenol-containing wastewater, thereby preventing secondary pollution and demonstrating greater environmental compatibility.
• Convenient and Rapid Installation: A basic concrete foundation suffices for installation; the tank can be set up within just a few days, resulting in savings on both installation costs and time. Furthermore, once installed, the tank can be immediately operational, significantly reducing project construction timelines.
• Cost Efficiency: Given that the tank's volume can be fully utilized without dead zones and its overall weight is considerably lighter, this design simplifies civil engineering requirements while lowering foundation costs. Compared to traditional dry or wet gas storage tanks, it offers a more economical solution.

Application

This system is suitable for the storage of biogas, air, carbon dioxide, oxygen,coal-bed gas, natural gas and other neutral gases. It is widely applicable across various sectors including livestock farming, wastewater treatment facilities, food waste processing plants, landfills, biogas production, and the chemical industry.
