Technical field
The present invention relates to a kind of seawater headwaters heat pump, especially a kind of sea water desaltination heat and cold supplier.
Background technology
At present, existing seawater headwaters heat pump mainly comprises vaporizer, compressor, condensing surface, throttling valve, and the condensing surface and the vaporizer of existing seawater headwaters heat pump all adopt the surface-type heat exchanger heat exchange usually; Refrigerant is enclosed in the system, does not directly contact with high cryogenic substance, and the heat transfer temperature difference loss is arranged; The surface-type heat exchanger heat exchange efficiency is still not too high; Heat-transfer capability is still less relatively, can only utilize the seawater sensible heat, does not have seawater desalination functions.
Summary of the invention
For condensing surface and the vaporizer that overcomes existing seawater headwaters heat pump all adopts the surface-type heat exchanger heat exchange usually, refrigerant is enclosed in the system, does not directly contact with high cryogenic substance; The heat transfer temperature difference loss is arranged, and the surface-type heat exchanger heat exchange efficiency is still not too high, and heat-transfer capability is still less relatively; Can only utilize the seawater sensible heat, not have the deficiency of seawater desalination functions, the present invention provides a kind of sea water desaltination heat and cold supplier; This sea water desaltination heat and cold supplier is constituted jointly by open type heat pump device and the freezing desalting equipment two portions of seawater, and this sea water desaltination heat and cold supplier does not adopt surface-type heat exchanger, and refrigerant is done open cycle in the hot cold transmittance process; Refrigerant directly contacts concurrent angry liquid phase change with water and carries out heat exchange, no heat transfer temperature difference loss, and the low-pressure liquid refrigerant directly contacts seawater; Through evaporation heat absorption seawater dynamic ice-making desalination simultaneously, the high-pressure gaseous refrigerant directly contacts cold water through the condensation heat release, reaches like this to make this sea water desaltination heat and cold supplier heat exchange efficiency very high; Heat-transfer capability is very big; Simple in structure, cold and heat combined supply, the purpose of by-product fresh water.
The technical solution adopted for the present invention to solve the technical problems is: this sea water desaltination heat and cold supplier is constituted jointly by open type heat pump device and the freezing desalting equipment two portions of seawater; The shared vaporizer of the freezing desalting equipment of open type heat pump device and seawater; It is open type that the refrigerant of vaporizer is imported and exported, and it is open type that the refrigerant of condensing surface is imported and exported; The open type heat pump device mainly comprises vaporizer, compressor, condensing surface, throttling valve, accumulation of heat water device etc., and the freezing desalting equipment of seawater mainly comprises vaporizer, washing separator, ice storage unit etc.; It also comprises pipeline, annex and the detection control apparatus that is connected in the system; Accumulation of heat water device is connected with condensing surface; Ice storage unit is connected with the washing separator.In the open type heat pump flow process; Low pressure gaseous coolant in the vaporizer gets into condensing surface after through compressor pressurizes; Direct contact cold water is through being condensed into liquid heat release in condensing surface for the high-pressure gaseous refrigerant, and the liquid refrigerants after the oily water separation gets into vaporizer through throttling valve and directly contacts seawater, absorbs the coagulation phase heating while seawater dynamic ice-making of seawater ice making through evaporation; Accomplish circulation, make the heat efficient high-speed of sea-water iceization flow to hot water like this; Throttling valve also can replace with decompressor during High Pressure Difference, and refrigerant adopts the low-boiling point material be insoluble in water such as butane etc.In the freezing desalination flow process of seawater, seawater gets into vaporizer through the seawater water inlet pipe, and seawater is dynamic ice-making in vaporizer, and the ice slurry gets into the washing separator again; Washing fresh water is got into by washing pipe, and concentrated seawater is discharged by the concentrated seawater rising pipe, and the washing separator can be a multi-stage type; Ice slurry after the washing gets into ice storage unit, and the ice in the ice storage unit can be converted into the fresh water cooling summer; Cold water gets into condensing surface by cold water inlet, the hot water entering accumulation of heat water device through heat absorption back, and hot water also can not get into accumulation of heat water device and directly effluxes during without accumulation of heat, and the hot water in the accumulation of heat water device can heat winter, heat supply water; Owing to adopt ice storage unit, accumulation of heat water device, can utilize wind-powered electricity generation ice making ice-reserving accumulation of heat water on a large scale; Hot water and the ice in the ice storage unit in the accumulation of heat water device can adopt thermo-electric generation, simultaneously by-product fresh water.
The invention has the beneficial effects as follows that this sea water desaltination heat and cold supplier heat exchange efficiency is very high, heat-transfer capability is very big, and is simple in structure, cold and heat combined supply, by-product fresh water.
