Abstract

Abstract: The liquid helium cryogenic system(LHCS) is an auxiliary facility of HL-2M tokamak, which is being built in Southwestern Institute of Physics(SWIP), the demand of liquid helium from cryogenic users are 16m³ per week. So it's necessary to construct a helium recovery and purification system (HRPS), which consists of a recovery part, a storage part and a purification part. The recovery part mainly includes 2 piston compressors with capacity 50m³/h and 100m³/h respectively; the storage part mainly includes 4800m³ higher purity helium tanks, 1200m³ dirty helium tanks and 50m³ two gasbags; the purification system mainly includes a high pressure helium purification equipment, which can improve the helium purity from 95% to 99.999% or even more. The maximum recovery rate of the system is designed to 150m³/h.

Key words: HL-2M, LHCS, HRPS, High pressure compressor
