Description
Technical field:
The present invention relates to a kind of sea water desalinating plant, but especially a kind of device of solar seawater desalination of saves energy.
Background technology:
Although water has covered the surface of the earth about 3/4, mostly be seawater, lake water etc. greatly, because of containing a large amount of impurity such as salt in the seawater, can't directly utilize.Therefore, the fresh water that can directly utilize on earth, 2 percent of not enough Total Water, for this reason, people are in the method for making great efforts to inquire into sea water desaltination.Up to the present,, as have plenty of with chemical process and remove impurity in the seawater, have plenty of with physical method and obtain pure fresh water, all exist the too high problem of desalinating cost though also invented the method for multiple sea water desaltination.In order to address this problem, the patent No. is that the Chinese utility model patent of 03212404.x discloses a kind of " solar energy sea water desalination apparatus ".This device is to be provided with water reservoir, be connected to the transparent heat insulating canopy with water reservoir, on the transparent heat insulating canopy, be provided with the water vapour relief outlet, be connected to the water vapor condensation pipe with steam outlet, the terminal of water vapor condensation pipe is provided with the distilled water water outlet, promptly utilize sun power to make evaporation of seawater, the fresh water behind the collection evaporative condenser is to realize sea water desaltination.But in order to accelerate the circulation of water vapour, just a suction fan must be installed between steam outlet and water vapor condensation pipe 4, carry out condensation by the strength of suction fan again after with the water vapour sucking-off, so just exist the problem of consumed power, Cost of seawater desalination is strengthened.
Summary of the invention:
The objective of the invention is in order to solve the high problem of existing in prior technology sea water desaltination cost, but a kind of save energy, energy-saving solar energy sea-water distillator that cost is low are provided.
Technical solution of the present invention is: be provided with evaporation of seawater pond 1, be provided with transparent heat insulating ceiling 2 above the evaporation of seawater pond 1, be connected to seawater input tube 3 with evaporation of seawater pond 1, also being provided with one side joins with evaporation of seawater pond 1, the cooling stave 4 that another side and transparent heat insulating ceiling 2 join, evaporation of seawater pond 1 is provided with fresh water receiving tank 5 with the joint of transparent heat insulating ceiling 2 and cooling stave 4, be connected to fresh water output tube 6 with fresh water receiving tank 5, front end at cooling stave 4 is provided with reflector 7, and the seawater input tube 3 that links to each other with evaporation of seawater pond 1 places the back of reflector 7.
Described seawater input tube 3 joins with seawater water reservoir 8 and then communicates with evaporation of seawater pond 1.
Described fresh water output tube 6 is by the 8 back outputs of seawater water reservoir.
The seawater input tube 3 that reflector 7 covers is serpentine bend and arranges.
Seawater concentrated solution output tube 9 is arranged below the described evaporation of seawater pond 1.
The present invention has constituted condensing chamber with reflector, cooling stave and seawater input tube, and the rapid condensation of water vapour that will evaporate through the solar irradiation seawater to obtain purified fresh water, can be widely used in tap water, irrigation, bathing etc.Compare with prior art, great advantage of the present invention is to need not the purpose that any electric energy just can realize that condensing rate is fast, sea water desaltination efficient is high, greatly reduces Cost of seawater desalination.Especially be provided with the seawater water reservoir, the fresh water output tube can carry out preheating to seawater by output again behind the seawater water reservoir, has accelerated the speed of the evaporation of seawater, the efficient of desalination more.The seawater concentrated solution can be by the output of seawater concentrated solution output tube, and twice transformation can be produced muriates such as salt after concentrating, and has high economic benefit and social benefit.
Description of drawings:
Fig. 1 is the structural representation of the embodiment of the invention.
Embodiment:
Below in conjunction with description of drawings the specific embodiment of the present invention.As shown in Figure 1: a kind of solar energy sea water desalination apparatus, be provided with evaporation of seawater pond 1, available brick, cement etc. are built into, and are preferably black at the bottom of the pond, are convenient to extinction.Be provided with transparent two sides insulation ceiling 2 above the evaporation of seawater pond 1, be connected to seawater input tube 3 with evaporation of seawater pond 1, be connected with the perpendicular cooling stave of putting 4 with transparent heat insulating ceiling 2, cooling stave 4 can be the plastics film of individual layer, the another side of cooling stave 4 with join with evaporation of seawater pond 1.Evaporation of seawater pond 1 is provided with fresh water receiving tank 5 with the joint of transparent heat insulating ceiling 2 and cooling stave 4, be connected to fresh water output tube 6 with fresh water receiving tank 5, front end at cooling stave 4 is provided with reflector 7, can be stainless steel plate, planar optics or benzene plate, the seawater input tube 3 that is the serpentine bend layout that links to each other with evaporation of seawater pond 1 places the back of reflector 7.A seawater water reservoir 8 preferably is set, and seawater input tube 3 communicates with evaporation of seawater pond 1 by seawater water reservoir 8, and fresh water output tube 6 is by the 8 back outputs of seawater water reservoir.For ease of collecting the seawater concentrated solution after evaporating, below evaporation of seawater pond 1, be connected to seawater concentrated solution output tube 9.
Working process:
With pump seawater is sent in the evaporation of seawater pond 1 by seawater input tube 3, sunlight shines by the seawater in 2 pairs of evaporation of seawater ponds 1 of transparent heat insulating ceiling and shines, generate water vapour, water vapour can generate in the globule inflow fresh water receiving tank 5 on transparent heat insulating ceiling 2 in direct condensation, by the fresh water output tube 6 output fresh water that join with fresh water receiving tank 5, place seawater water reservoir fresh water output tube 6 to carry out preheating, to accelerate the velocity of evaporation of seawater to seawater.Most of water vapour flows in the condensing chamber that is made of reflector 7, seawater input tube 3 and cooling stave 4 automatically, water vapour will generate in the globule inflow fresh water receiving tank 5 on cooling stave 4, seawater input tube 3 in condensation, by the fresh water output tube 6 output fresh water that join with fresh water receiving tank 5, water vapour plays pre-heat effect to the seawater in the seawater input tube 3, also can accelerate the velocity of evaporation of seawater.
