Abstract
The invention discloses a sea water desalination device, which belongs to the field of sea water desalination. For solving the problem that the service conditions of an existing distilled sea water desalination device are restricted by the working conditions of a host, and the existing distilled sea water desalination device is complex in system and not easy to manage, the invention provides a self-contained sea water desalination device. The sea water desalination device comprises a pump, an enclosed heat exchanger, an evaporator, a condenser, a water collector and a fresh water tank which are sequentially connected, wherein the enclosed heat exchanger is externally connected with a heat source, the condenser and the water collector are located on the upside of the inside of the evaporator, and the water collector is located below the condenser. When used for carrying out desalination on sea water, the device can be used independently without being affected by the working conditions of a diesel engine on a ship; and the device is easy to operate, a refrigerant is recycled in the device, and the power consumption is small.
Description
Technical field
The invention belongs to field of seawater desalination.
Background technology
At present, big-and-middle-sized naval vessel is all equipped with sea water desalinating plant, be mainly distillation type, reverse osmosis type, electrodialysis formula etc., most widely used is distillation type, thermal source is primarily of the used heat in electric energy, hot water, steam and combustion turbine exhaustion, conventional distilling sea water desalter mainly carries out sea water desaltination using diesel engine cooling smuggled goods steam as thermal source, its working conditions limits by main frame working condition, just can carry out sea water desaltination when only having main powerplant to work, and system complex, be not easy to management.
Summary of the invention
The object of this invention is to provide a kind ofly can independently to use, the sea water desalinating plant of easy handling.
The present invention is achieved by the following technical programs: a kind of sea water desalinating plant, comprise the pump, blanket heat exchanger, vaporizer, condenser, water collector and the fresh water tank that are connected successively, the external thermal source of described blanket heat exchanger, described condenser and described water collector are positioned at described vaporizer inner upper, and described water collector is positioned at below described condenser.
Described vaporizer is also communicated with sewage tank, and described vaporizer is provided with interchanger on the pipeline of sewage tank.
Described thermal source is compression heat pump.
Described blanket heat exchanger connects described vaporizer by nozzle.
Described compression heat pump, blanket heat exchanger, condenser internal refrigeration storage agent pipeline are communicated with successively, form circulation line.
In described blanket heat exchanger, refrigerant tubing outlet is communicated with by expansion valve with refrigerant tubing entrance in described condenser.
Described pump passes described interchanger to the seawater inlet channel of described hermetic compressor.
The present invention has following beneficial effect:
Use independent thermal source, utilize refrigeration agent state in vaporizer and condenser to carry out sea water desaltination as cold and heat source, can use alone, not limit by diesel engine working condition on ship, self-organizing system, easy handling.
Accompanying drawing explanation
Below in conjunction with specific embodiment, the present invention will be further described.
Fig. 1 is the structural representation that the invention provides a kind of sea water desalinating plant.
In figure: 1. pump, 2. vaporizer, 3. blanket heat exchanger, 4. compression heat pump, 5. condenser, 6. interchanger, 7, nozzle, 8. clear water cabinet, 9. sewage tank, 10. expansion valve, 11. water collectors.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the present invention is described further.
Embodiment: as shown in the figure, the sea water desalinating plant running that the present invention describes is as follows: seawater is delivered in blanket heat exchanger 3 by pump 1, spray in vaporizer 2 by nozzle 7 after being heated to required temperature, part seawater becomes steam, and non-evaporation section is stayed in vaporizer 2, enters sewage tank 9 by reducing temperature after interchanger 6, finally discharge, evaporation gained steam rises in vaporizer 2 inside, is cooled to water, enters clear water cabinet 8 after water collector 11 in condenser 5.For making full use of heat energy, seawater, before pump 1 is transported to blanket heat exchanger 3, carries out preheating through interchanger 6, reduces the heated pressure of compression heat pump 4.
Refrigerant circulating process: the thermal source of blanket heat exchanger 3 is supplied by compression heat pump 4, the compressor temperature of refrigeration agent in compression heat pump 4 by compression in formula heat pump 4 raises and becomes thermal source heating seawater in closed interchanger 3, after blanket heat exchanger 3, condensation of refrigerant becomes liquid, to enter after expansion valve 10 in the condenser 5 of sea water desalinating plant as low-temperature receiver with condensation evaporation of seawater gained water vapour, refrigeration agent evaporates wherein becomes steam state, again sucked by the compressor in compression heat pump 4, complete condensing agent circulation.
Sea water desalinating plant described in the embodiment of the present invention, directly utilizes the vaporizer of heat pump and condenser to carry out sea water desaltination as cold and heat source, can independently use, do not limit, self-organizing system by diesel engine working condition on ship, simultaneously easy handling, and current consumption is little.
Above content is the further description done the present invention in conjunction with concrete embodiment, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
