Description

Technical Field

[0001] The utility model relates to the technical field of helium recovery, in particular to a helium recovery and recycling device. Background Art

[0002] Helium is a rare gas with the chemical formula He. It is colorless and odorless, and its chemical properties are inactive. Under normal conditions, it is difficult to react with other substances. Helium is the second most abundant element in the universe after hydrogen, accounting for about 24% of the mass of galaxies. At room temperature, helium is an extremely light, colorless, odorless, and tasteless monatomic gas. It is the most difficult of all gases to liquefy and is a substance that cannot solidify under standard atmospheric pressure. After liquefaction, when the temperature drops to 2.174K, it has special properties such as very small surface tension, strong thermal conductivity, and extremely low viscosity. Liquid helium can be used to achieve low temperatures close to absolute zero. Helium should be stored upright in a well-ventilated, safe place that is not affected by weather. The storage temperature must not be higher than 52°C. There should be no flammable materials in the storage area and it should be away from frequent entry and exit points and emergency exits. There should be no salt or other corrosive materials.

[0003] Liquid helium cryogenic system has a wide range of applications. The operation of liquid helium cryogenic system adopts liquid helium immersion cooling. Due to heat leakage of cryogenic container, liquid helium evaporates continuously, and gasified helium is directly released into the air, causing the liquid level to drop. In order to maintain the operation of cryogenic system, liquid helium must be added continuously. In order to save energy, helium is generally recycled for recycling. Since the recycled helium contains large particles, dust, lint, etc., these impurities will enter the recovery system together with the helium, affecting the recovery concentration of helium and even damaging the recovery equipment.
