Liquid argon storage tank is a specialized equipment for storing liquid argon, and is one of the common and important equipment in modern industry and scientific research fields. The main function of a liquid argon storage tank is to store argon gas, keeping it in a low temperature and high pressure state for easy transportation, storage, and use.
The main body of liquid argon storage tanks mostly adopts a double shell structure, with insulation materials filled between the inner and outer shells to maintain the liquid argon in a low-temperature state for a long time. The main body of the storage tank consists of the tank body, upper cover, and lower bottom, as well as auxiliary equipment such as pressure measurement, safety valves, and inlet and outlet.
Liquid argon storage tanks are generally divided into two types, namely static storage tanks and mobile storage tanks. Static storage tanks are generally installed in fixed locations and are mainly used in fields such as semiconductor electronics, medicine, and chemical engineering. Mobile storage tanks are like storage barrels in action, suitable for industries that require frequent use of liquid argon, such as synthetic crystals, gas separation, arc welding, and ion implantation.
The working principle of a liquid argon storage tank is to transport high-pressure gas into the tank, liquefy the gas by reducing temperature and pressure, and then store the liquid argon in the tank body. The boiling point of liquid argon in the storage tank is -185.9 ℃ at atmospheric pressure and -189.3 ℃ at atmospheric pressure. During transportation and storage, liquid argon needs to be kept in a low-temperature state by cooling down to ensure that the argon does not gasify, thereby minimizing the leakage of argon.
The safety of liquid argon storage tanks is very important because liquid argon can explode under certain conditions. Therefore, special attention should be paid to safety issues in the design and manufacturing of liquid argon storage tanks. At the same time, the pressure, temperature, and liquid level inside the storage tank also need to be monitored and controlled in real-time to ensure the stability and safety of the storage tank.
Overall, liquid argon storage tanks are one of the indispensable and important equipment in modern industry. It can effectively store argon gas for industrial and scientific research needs. With the development of technology, the structure and performance of liquid argon storage tanks are constantly innovating and improving, providing better protection and support for the development of various industries.
