Description
Technical field
The present invention relates to the refrigeration machine in Refrigeration ＆ Cryogenic Technique field, specially a kind of multicomponent mixture work medium single-stage separation
Circulating with choke cryogenic refrigeration system.
Background technology
J-t refrigerator of multiple non-azeotropic refrigerant of current nearly more than ten years fast development, by compressor, oil
From device, condenser, device for drying and filtering, contra-flow heat exchanger, evaporator and restricting element composition.Its is simple in construction, and the thermal efficiency compared with
It is high.
But it is due to once to be throttled using multiple non-azeotropic refrigerant, high-temperature level working medium all participates in evaporator circulation,
So evaporator temperature sliding is big；And the oily separating effect of high temperature oil eliminator is poor, lubricating oil is easily solid in below 200K
Change, so when producing below 200K low temperature, oily stifled and evaporator heat exchange efficiency easily occur and declining；And using polynary non-
Azeotropic mixed working medium once throttles, when starting at the beginning of refrigeration machine, because numerous low-temperature level working medium can not be condensed, in evaporator return-air
Circulated under thermal resistance very slowly, cause system high pressure too high, low pressure is too low, compression ratio is too high, excessive discharge temperature；And with target system
The decline of temperature is taken, the rising of environment temperature, this phenomenon becomes apparent from；Cause the reliability decrease of refrigeration machine.
Another fast-developing multiple non-azeotropic refrigerant separation circulating refrigerator, a point single-stage separation is circulated and many
Level separation circulation, single-stage rectifying Refrigeration cycle and multistage rectification Refrigeration cycle.
Single-stage separation circulation is characterized in the mixed working fluid of compressor discharge after being condensed under normal temperature environment by gas-liquid point
From device, it is divided into liquid phase component throttling and gaseous component carries out countercurrent flow, gaseous component liquefaction deutomerite flows into evaporator refrigeration.
Multi-stage separation circulation is characterized in the mixed working fluid of compressor discharge after being condensed under normal temperature environment by gas-liquid point
From device, it is divided into liquid phase component throttling and gaseous component carries out countercurrent flow, gaseous component connects again after being cooled through countercurrent flow
Enter gas-liquid separator, so constantly superposition, the series until being stacked to needs；The gas phase that afterbody is isolated again is through adverse current
Heat exchange liquefaction deutomerite flows into evaporator refrigeration.
Single-stage rectifying Refrigeration cycle is characterized in that the mixed working fluid of compressor discharge is passed through after being condensed under normal temperature environment
Rectifying fractional condensation gas-liquid separator is crossed, is divided into liquid phase component throttling and gaseous component carries out countercurrent flow, gaseous component liquefaction deutomerite
Flow into evaporator refrigeration；Rectifying fractional condensation vapour liquid separator is compared with conventional separator, and being added on top has vertical direction outlet to lead to
There is rectifying column at the return-air heat exchanger in road, middle part, and mixed working fluid enters from bottom, risen by rectifying column, isolate most of liquid
Phase, gas phase becomes drop using the cooling of return-air cold, and drop declines inflow rectifying column and separated again, increases the liquid phase component of separation
Ratio.
Multistage rectification Refrigeration cycle is characterized in complete equivalent to all common gas-liquid separators that multi-stage separation is circulated
Portion is substituted for the rectifying fractional condensation vapour liquid separator in single-stage rectifying Refrigeration cycle；Other are as multi-stage separation circulation.
Separate and circulate for single-stage, because burble point is circumstance temperature, cause also to contain excessively in the gas phase composition after separation
Enter evaporator evaporation after high-temperature level working medium component, countercurrent flow, contrast the temperature glide of a j-t refrigerator, without very big
Improvement, simply improve oily separating effect.Single-stage rectifying Refrigeration cycle, although improve mixed working fluid separating effect,
But rectifying fractional condensation separator is non-universal component, and internal structure is complicated, adds manufacture difficulty.
For multi-stage separation circulation, due to separation series increase, cause system complex, reliability decrease.Multi-level oil cut
Comparatively, system is more complicated, adds manufacture difficulty for solidifying separation circulation.
Circulated similarly, since being separated using multiple non-azeotropic refrigerant, when starting at the beginning of refrigeration machine, low-temperature level working medium exists
Under evaporator return-air thermal resistance, do not circulate substantially, cause system high pressure too high, low pressure is too low, compression ratio is too high, delivery temperature mistake
It is high；And the reduction of temperature is produced with target, the rising of environment temperature, this phenomenon becomes apparent from；Cause the reliability of refrigeration machine
Decline.
