When existing apparatus is transformed, if being intended to existing brine being changed to glacial epoch refrigerant completely, improvement expenses must be caused more high,
And the normal operation of process units can be influenced.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of glacial epoch refrigerant substitute salt-ice refrigeration the circulatory system,
For brine by heat exchanger to glacial epoch coolant refrigeration, glacial epoch refrigerant after cooling is used further to chemical production device refrigeration.
Technical solution adopted by the utility model to solve its technical problems is：A kind of glacial epoch refrigerant substitutes salt-ice refrigeration
The circulatory system, including brine recycling circuit and glacial epoch refrigerant circulation circuit, the brine in the brine recycling circuit is as low-temperature receiver
Freezed to the glacial epoch refrigerant in the glacial epoch refrigerant circulation circuit by heat exchanger；
Wherein, condenser is configured in the glacial epoch refrigerant circulation circuit, for freezing to chemical production device.
Further, the heat exchanger is plate heat exchanger.
Further, it is also configured with delivery pump in the glacial epoch refrigerant circulation circuit, for cold to glacial epoch in the circuit
The cycle of matchmaker provides power.
Further, it is also configured with storagetank in the glacial epoch refrigerant circulation circuit, the storagetank is for storing glacial epoch
Refrigerant, entrance side are connected with the plate heat exchanger, and outlet side is connected with the delivery pump.
Further, in the plate heat exchanger, the mesohalobic flow direction in brine recycling circuit and glacial epoch refrigerant
The flow direction of glacial epoch refrigerant is opposite in circulation loop.
The utility model has the beneficial effects that：Utilize existing refrigeration system（That is brine recycling circuit）The required temperature of conveying
Brine heat exchange refrigeration is carried out to the glacial epoch refrigerant in the refrigerant circulation circuit of glacial epoch by plate heat exchanger, then set by power
It is standby（That is delivery pump）Glacial epoch refrigerant after heat exchange is transported in the condenser of chemical production device and is freezed, glacial epoch is cold later
Matchmaker returns again to plate heat exchanger and continues to exchange heat, can be constantly to the ice after condenser conveying refrigeration to form circulation loop
River refrigerant；Plate heat exchanger need to only be repaired, be replaced when the advantage of this system is to safeguard, reduce repair and maintenance
Cost, and system also have the advantages that it is safe efficient.
