What methods can be used to improve the storage conditions of liquid argon?
1. Choose a suitable storage tank
High-efficiency insulation storage tank:
Vacuum interlayer storage tank: adopt a double-layer tank design, and the middle interlayer is evacuated to reduce heat conduction and improve the insulation effect.
Multi-layer insulation material: Use multi-layer insulation materials such as aluminum-coated polyester film, foam glass, etc. to further improve the insulation performance of the storage tank.
Special low-temperature storage tank:
Low-temperature steel: Select low-temperature resistant materials such as austenitic stainless steel for manufacturing storage tanks to ensure stable mechanical properties in extremely low temperature environments.
2. Environmental temperature control management
Constant temperature warehouse:
Establish a constant temperature warehouse around the liquid argon storage tank, maintain the ambient temperature stable through temperature control equipment, and reduce the impact of external temperature on liquid argon.
Auxiliary heat dissipation system:
Equipped with heat dissipation equipment, such as a cooling water circulation system, to help cool the outside of the storage tank and reduce the impact of ambient heat on the temperature of liquid argon.
3. Regular maintenance and testing
Sealing inspection:
Regularly check the sealing of storage tanks and pipelines to ensure no leakage. In particular, check the sealing performance of valves, flanges and joints.
Insulation layer maintenance: Regularly check whether the insulation layer is intact. If damaged or aged parts are found, they should be replaced or repaired in time.
4. Optimize storage operation process
Quick filling and unloading: Shorten the time of filling and unloading liquid argon, reduce the time of liquid argon contact with the external environment, and reduce evaporation loss.
During operation, try to reduce the frequent opening and closing of the tank cover and valve to maintain the low temperature environment in the tank.
Use appropriate filling equipment: Use special low-temperature filling equipment to ensure that the liquid argon maintains a stable low-temperature state during the filling process and reduce gasification loss.
5. Use advanced monitoring system
Real-time temperature monitoring: With real-time temperature monitoring device, monitor the temperature changes inside and outside the tank 24 hours a day, detect abnormal conditions in time and take measures to adjust.
Liquid level monitoring: Use liquid level sensor to monitor the actual inventory of liquid argon to avoid overstorage or shortage.
6. Gas recovery and reuse
Condensation recovery equipment: Install condensation recovery device at the outlet of the tank to capture evaporated argon, condense and recover it, liquefy it again and return it to the tank.
Secondary utilization system:
Establish a secondary utilization system for argon gas, recycle and reuse the argon gas evaporated during storage, and improve resource utilization.
Conclusion
Through the above methods, enterprises can significantly improve the storage conditions of liquid argon, reduce unnecessary losses, and ensure that liquid argon remains stable during storage. This not only helps to reduce production costs, but also improves work efficiency and safety. As an important industrial gas, the efficient storage of liquid argon is of great significance to the development of all walks of life. It is hoped that the suggestions provided in this article can provide practical guidance for relevant enterprises and jointly promote the progress and development of the industrial gas field.
