Specific embodiment
Principle of the invention, structure and concrete mode are described further below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of heat pump sea water desalting apparatus.The device mainly includes heat pump, sea water evaporating installation
13rd, condensing heat exchanger 6, desalination water tank 8；The heat pump includes expansion valve 2, condenser 3, compressor 4 and evaporator 5.
Ambient seawater enters condensing heat exchanger via seawater inlet, is changed with high temperature saturated moist air in condensing heat exchanger
Heat, absorbs the condensation heat of high temperature saturated moist air, is once heated up.
Seawater after once heating up carries out secondary temperature elevation into heat pump.In heat pump, the liquid system of low-temp low-pressure
Cryogen absorbs the heat of low-temperature heat source and gasifies in evaporator, and compressor sucks the gaseous refrigerant of low temperature, by low-temp low-pressure
Gaseous refrigerant be collapsed into the gaseous refrigerant of HTHP, and be transported in condenser, the gaseous refrigerant of HTHP
Agent is condensed within the condenser, to high temperature heat source heat release, is changed into the liquid refrigerant of HTHP, the liquid refrigerant of HTHP
Again by expansion valve liquid refrigerant of the throttling as low-temp low-pressure.In the present invention, low-temperature heat source is condensing heat exchanger humid air
The humid air of side outlet, high temperature heat source is the seawater after once heating up.Seawater after once heating up enters the condensation of heat pump
The condensation heat of high temperature and high pressure gaseous refrigerant is absorbed in device, secondary temperature elevation is carried out.
Seawater after secondary temperature elevation enters sea water evaporating installation with the ring entered via the air intake of sea water evaporating installation
Border air directly contact carries out hot and humid area.When seawater and surrounding air directly contact, due to the evaporation operation of water drops surface,
One layer of saturated air thin layer is formed in water drops surface.Because the steam partial pressure in seawater surface saturated air layer is more than environment
The steam partial pressure of air, then can cause the hydrone in seawater surface saturated air layer to jump into surrounding air, then environment is empty
Gas is humidified.The temperature difference of high temperature seawater and surrounding air so that heat is transmitted to surrounding air, surrounding air temperature by high temperature seawater
Degree is raised.The result of hot and humid area shows as, seawater cooling, and it is to be had enough to eat and wear close to the height of saturation state that surrounding air is heated humidification
And humid air.
The high temperature saturated moist air of sea water evaporating installation outlet is threaded a pipe by humid air stream and enters condensing heat exchanger, with ring
Border seawater to make heat exchange, is once condensed.Because the dew-point temperature of high temperature saturated moist air is close to its dry-bulb temperature, and environment is extra large
The temperature of water is less than the dew-point temperature of high temperature saturated moist air, so high temperature saturated moist air is highly exothermic in condensing heat exchanger
Condensation, temperature and humidity is reduced, and is changed into humid air, and ambient seawater is once heated up in condensing heat exchanger.Condensation is changed
The fresh water obtained in hot device flow to fresh-water tank by condensate pipe.
The humid air of condensing heat exchanger humid air side outlet enters the further exothermic condensation of evaporator of heat pump, condensation
The fresh water for obtaining enters fresh-water tank by the condensate pipe of evaporator.
Fig. 2 is the structural representation of the heat pump sea water desalting apparatus that with the addition of Intermediate Heat Exchanger.After avoiding device operation
The scale problems of condenser, on the basis of device 1, set up Intermediate Heat Exchanger 11.Heat transfer medium enters the condensation of heat pump
The condensation heat that the gaseous refrigerant of HTHP is absorbed in device is heated up, and ambient seawater is once heated up in condensing heat exchanger
Afterwards, heat exchange is carried out into Intermediate Heat Exchanger and heat transfer medium, obtains secondary temperature elevation.Seawater after secondary temperature elevation steams into seawater
Hair equipment, with described in device 1.
In the prior art that the content not described in detail in specification is known to the skilled person.
