Gas-liquid separation being carried out by reservoir 204 afterwards and forming cryogenic high pressure liquid, then carrying out water removal by device for drying and filtering 205 removes
Miscellaneous, then by the formation low temperature and low pressure liquid of throttling arrangement 207, low temperature and low pressure liquid is in heat-exchanger rig 102 by heat exchange shape
Into low-temp low-pressure gas liquid mixture, low-temp low-pressure gas liquid mixture carries out gas-liquid separation by gas-liquid separator 201 and forms low temperature
Low-pressure gas, then process compressor 202 is compressed to form high temperature and high pressure gas low temperature low pressure gas again, back and forth above-mentioned to follow
Ring, so that 200 pairs of hydraulic oil by the hydraulic oil transfer pipeline 100 of heat-exchanger rig 102 of cooling line is cooled down.It is wherein cold
But the effect of the cooling line by-passing valve 208 in pipeline 200 is that pressure in cooling line 200 persistently raises and reaches certain value
When, cooling line by-passing valve 208 opens progress pressure release and cooling line 200 is played a protective role；Cooling line magnetic valve 206
Effect is that, when cooling line 200 is inoperative, the liquid for placing the front of cooling line magnetic valve 206 flow to compressor 202 backward
It is interior so that compressor 202 is damaged, and is played a protective role.
