Abstract

A kind of low temperature on-condensible gas cold recovery system, including double rectification column and heat exchanger, pressure nitrogen gas pipeline and low temperature on-condensible gas pipeline are connected with heat exchanger, low temperature on-condensible gas pipeline is connected with the waste gas outlet of the condenser/evaporator in the middle part of double rectification column, and pressure nitrogen gas pipeline and the pressure nitrogen gas outlet of tower under double rectification column connect.The utility model provides a kind of low temperature on-condensible gas cold recovery system, and by the recycling of on-condensible gas cold, cold recovery is carried out on the premise of energy consumption is not increased, high-purity liquid nitrogen yield is added, reduces product energy consumption.

Description

Low temperature on-condensible gas cold recovery system
Technical field
The utility model belongs to gas separation technique field, refers in particular to a kind of low temperature on-condensible gas cold recovery system.
Background technology
Full liquid space division has several strands of not solidifying cryogenic gases to be discharged into air, such as neon helium, is continuously drained into equipment running process Air, causes very High cooling power loss.
Utility model content
The purpose of this utility model is to provide a kind of low temperature on-condensible gas cold recovery system, passes through on-condensible gas cold Recycling, cold recovery is carried out on the premise of energy consumption is not increased, high-purity liquid nitrogen yield is added, reduces product energy consumption.
What the purpose of this utility model was realized in:A kind of low temperature on-condensible gas cold recovery system, including twin-stage essence Evaporate tower and heat exchanger, be connected with pressure nitrogen gas pipeline and low temperature on-condensible gas pipeline on heat exchanger, low temperature on-condensible gas pipeline with it is double The waste gas outlet connection of condenser/evaporator in the middle part of level rectifying column, the pressure nitrogen gas of pressure nitrogen gas pipeline and tower under double rectification column Outlet connection.
Preferably, low temperature on-condensible gas pipeline connects the heat exchanger, and the heat exchanger is aluminium-made plate type heat exchanger.
Preferably, cold is exchanged heat and is lowered temperature to pressure nitrogen gas, pressure nitrogen gas by low temperature on-condensible gas by heat exchanger After become liquid nitrogen.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that:
The exhaust gas such as the low temperature neon helium discharged in space division condenser/evaporator are separated through aluminium-made plate type heat exchanger with air separation plant The middle pressure high pure nitrogen gone out carries out heat exchange, and middle pressure high pure nitrogen is liquefied, and obtains the exhaust gas such as high-purity liquid nitrogen product, low temperature neon helium Air is discharged into after re-heat to room temperature.The technology is carried out cold by the recycling of on-condensible gas cold on the premise of energy consumption is not increased Amount recycling, adds high-purity liquid nitrogen yield, reduces product energy consumption.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1:
A kind of low temperature on-condensible gas cold recovery system, including double rectification column and heat exchanger, are connected with pressure on heat exchanger Nitrogen pipeline and low temperature on-condensible gas pipeline, the exhaust gas of low temperature on-condensible gas pipeline and the condenser/evaporator in the middle part of double rectification column Outlet connection, pressure nitrogen gas pipeline and the pressure nitrogen gas outlet of tower under double rectification column connect.
Preferably, low temperature on-condensible gas pipeline connects the heat exchanger, and the heat exchanger is aluminium-made plate type heat exchanger.
Preferably, cold is exchanged heat and is lowered temperature to pressure nitrogen gas, pressure nitrogen gas by low temperature on-condensible gas by heat exchanger After become liquid nitrogen.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that:
The exhaust gas such as the low temperature neon helium discharged in space division condenser/evaporator are separated through aluminium-made plate type heat exchanger with air separation plant The middle pressure high pure nitrogen gone out carries out heat exchange, and middle pressure high pure nitrogen is liquefied, and obtains the exhaust gas such as high-purity liquid nitrogen product, low temperature neon helium Air is discharged into after re-heat to room temperature.The technology is carried out cold by the recycling of on-condensible gas cold on the premise of energy consumption is not increased Amount recycling, adds high-purity liquid nitrogen yield, reduces product energy consumption.
Above-described embodiment is only the preferred embodiment of the utility model, not limits the protection model of the utility model according to this Enclose, therefore:The equivalence changes that all structures, shape, principle according to the utility model are done, should all be covered by the protection of the utility model Within the scope of.
