Description

Technical Field

[0001] This utility model relates to the field of double-membrane gas storage tank technology, and in particular to a leak prevention monitoring device for double-membrane gas storage tanks. Background Technology

[0002] A double-membrane gas holder is a special type of gas storage equipment, mainly used for storing neutral gases such as biogas, air, and carbon dioxide. Its structure primarily consists of a bottom membrane (except for integrated gas holders), an inner membrane, an outer membrane, a constant pressure control cabinet, and safety protectors. The inner and outer membranes of the double-membrane gas holder are made of high-strength polyester or polyurethane materials, possessing excellent airtightness, mechanical strength, and corrosion resistance. The bottom membrane is mainly used for foundation sealing, achieving advantages such as corrosion prevention, leak prevention, simplified installation, and long service life. The inner membrane stores the gas, while the outer membrane provides protection. Simultaneously, a space is formed between the inner and outer membranes. The pressure regulating space, through constant pressure control cabinet and safety protectors, regulates and controls the pressure inside the gas holder to ensure its stability and safety. The double-membrane gas holder has many advantages, including convenient and quick installation, small footprint, long corrosion resistance, and high safety and reliability. Its installation process is simple, requiring only a basic cement base, and can be completed in a few days, greatly saving installation costs and time. In addition, the main materials of the double-membrane gas holder have a long corrosion resistance and excellent natural anti-aging properties in terms of resistance to ultraviolet rays, microorganisms, and weathering, which can ensure the long-term stable operation of the gas holder.

[0003] The existing technical solutions mentioned above have the following drawbacks: Existing dual-membrane gas storage tanks have gas pressure detection devices on the outside of the gas pipeline to prevent gas leakage. However, there is a lack of easy-to-use leak prevention monitoring devices in the space between the inner and outer membranes. Once the gas in the inner membrane leaks, it cannot be monitored in time, resulting in low safety. Utility Model Content
