CIRCULATION-TYPE LIQUID HELIUM RELIQUEFACTION APPARATUS WITH CONTAMINANT DISCHARGE FUNCTION AND METHOD OF DISCHARGING CONTAMINANT FROM THE APPARATUS |
摘要 |
This invention relates to a circulation type liquid helium recondensation device with a contaminant-purging function capable of vaporizing and removing contaminants deposited on the refiner in the device. Helium gas vaporizing in the liquid helium storage tank 2 is pumped by the circulating pump 7 and refined in the refiner 6. The refiner is provided with heaters and also a discharge circuit on the inflow side. The vaporized contaminants generated when the refiner 6 is heated by the heaters are pumped by the circulating pump 7 or the dedicated purge pump 8 and vented to the atmosphere via said discharge circuit. <IMAGE> |
