Description
Technical field
The present invention relates to sea water desaltination field, especially relate to a kind of device that utilizes natural energy resources to desalinize seawater.
Background technology
Sea water desaltination is the problem that people pay close attention to always.The method that seawater is desalinated is a lot, but conventional method, as multistage distillation method, ion exchange method, dialysis, reverse osmosis membrane and cold method etc., all will consume a large amount of fuel or electric power.Because Greenhouse effect, the atmospheric pollution of the earth are day by day serious, therefore, seek to carry out sea water desaltination with sun power, be subject to people's attention.
Disc type solar energy distillation device desalination technology has many advantages: be first can independent operating, be not subject to the condition restriction such as steam, electric power, pollution-free, operating safety is reliable and stable, does not consume conventional artificial energy source, and there is to very large using value in energy scarcity, the high area of environmental requirement; Next is that industrial scale can organic assembling, and adaptability is good, invests relatively less.
But its weak point is to occupy a large amount of land resourceses, is secondly to enter winter, a little less than intensity of solar radiation, cause fresh water yield low.If can improve the problems referred to above, desalination with Solar Energy possesses the competitive power in water supply market more.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, the object of this invention is to provide a kind of like this solar energy sea water desalination apparatus: first, it does not take land resources, utilize wide sea to settle sea water desalinating plant, second, enter winter, can utilize nature cold icing method desalinizing seawater in device to produce fresh water, to improve the fresh water aquifer yield in winter.

Embodiment
(seeing Fig. 4 and Fig. 5) device of the present invention mainly comprises the hull 1 that can float in water, sets gradually lower storage reservoir 2, upper storage reservoir 3, printing opacity canopy 4 in hull; At the bottom of upper storage reservoir pond, establish a drainage hole 31 and be communicated with lower storage reservoir; Upper storage reservoir top is provided with distillation tank 32, and distillation tank is communicated with lower storage reservoir by distillation water channel 33; An anchor ring 11 is fixed in hull bottom, and anchor ring can connection cable 12 and anchor (figure does not go out), can make like this hull be docked in a certain marine site, particularly can be docked in the region of high-quality seawater.
In upper storage reservoir 3, be provided with occluding mechanism, occluding mechanism comprises connected successively spring 34, kickboard 35, stay cord 36, stopper 37, and one end of its medi-spring is fixed on upper storage reservoir, and the other end is pressed in kickboard; Stopper is blocked drainage hole by deadweight, and when kickboard overcomes spring force and makes progress, by soft stay cord, pull-up stopper departs from drainage hole;
In lower storage reservoir 2, be provided with water-accepting basin 5, in the pulley groove 24 of water-accepting basin bottom and lower storage reservoir, be provided with pulley 25 and stay cord 26, one end of stay cord is fixed on lower storage reservoir 2 tops, the other end is connected with canopy lid 42, when water-accepting basin fills after water, under the effect of water gravity, water-accepting basin passes through pulley, pull stay cord, make the mobile also enclosed ventilation mouth of canopy lid;
Upper storage reservoir is provided with the ventpipe 61(being fixed at the bottom of pond and sees Fig. 5), one end of ventpipe is higher than distillation tank 32, and the other end stretches into lower storage reservoir 2;
The step that application said apparatus is made fresh water:
First step: closing on temperature lower than the time below 0 ℃, removing canopy lid 42, exposing ventilation opening 41, and add seawater (conventionally using water pump operation) in upper storage reservoir 3, the height of seawater to the lower plane of kickboard 35 (see figure 4) that is as the criterion.At temperature, lower than the time below 0 ℃, the seawater in upper storage reservoir freezes in freezing air, and (while freezing, the salt in seawater can be discharged from outside ice crystal.But still have some salts to have little time to discharge icing ice sheet rapidly, when these some salts need that ice sheet starts to melt afterwards, first the gap between ice crystal, with the water melting, discharge ice sheet).When ice is tied certain thickness, due to ice volumetric expansion, promote kickboard 35, overcome spring force upwards, by soft stay cord 36, stopper 37 is pulled up, not icing seawater is shown in Fig. 6 from drainage hole 31 inflow water-accepting basins 5 and lower storage reservoir 2();
After the water of water-accepting basin 5 fills, under water action of gravity, water-accepting basin pulls stay cord 26 by pulley 25, canopy lid 42 is moved and enclosed ventilation mouth 41, so that upper storage reservoir 3 is isolated from the outside; After this, owing to no longer needing water gravity to work, the seawater in water-accepting basin can slowly spill from aperture 51, until leaked.
(see figure 5) sunlight sees through printing opacity canopy 4, and the air in heating printing opacity canopy, in order to melt ice; Due to hot pressing effect, the warm air in canopy flows into ice sheet bottom through ventpipe 61, also in order to melt ice; Salty frozen water in ice releases from ice crystal gap gradually, through drainage hole 31, flows into lower storage reservoir 2; Afterwards, ice sheet melts gradually, and kickboard 35 is declined by the compressing of spring 34 gradually, and stopper 37 also declines thereupon;
When ice sheet is thinned to a certain degree through melting, the salinity of the salty frozen water of particularly discharging when the time comes has been less than after 1 ‰ (the saliferous standards of fresh water), stopper is blocked drainage hole completely by deadweight, and (this operating mode can be determined by adjusting the length of stay cord 36, after the salty frozen water salinity of discharging has been less than 1 ‰, guarantee that the length of stay cord 36 can allow stopper block drainage hole 31.The length of stay cord can keep permanent use after once determining).After this, the ice in upper storage reservoir continues to melt, and turns to fresh water;
Until the ice in upper storage reservoir all turns to fresh water;
Second step: take out the fresh water in upper storage reservoir 3; Concentrated seawater in lower storage reservoir 2 is also taken out, pump into afterwards seawater flushing lower storage reservoir and drip tray one time, to dilute the salinity of residual concentrated seawater.Then pump the seawater of this flushing, the aperture of the drainage hole of upper storage reservoir 31 and drip tray 51 is blocked; Enter solar distilling seawater operation:
In upper storage reservoir 3, add seawater, close canopy lid 42, sunlight sees through printing opacity canopy 4, (in fact upper storage reservoir becomes a traditional solar energy sea water distiller to seawater in heating upper storage reservoir, upper storage reservoir pool wall can be established a thermal insulation layer insulation, and surperficial blacking is beneficial to heat absorption) make evaporation of seawater, water vapor rises; Because printing opacity canopy itself heat absorption is few, temperature is lower than warm water in pond, and water vapor is met cold on printing opacity canopy 4, condenses into water droplet, along the inclined-plane of printing opacity canopy, drops down, and falls into distillation tank 32, through distillation water channel 33, flows in the distilled water of lower storage reservoir 2(drip trays 5 at lower storage reservoir and floats).Although the distilled water in lower storage reservoir can be sneaked into seawater salinity residual in lower storage reservoir, as long as this salinity does not surpass the salinity standard of fresh water.
When the seawater of upper storage reservoir is concentrated to a certain degree, take out concentrated seawater, also take out the distilled water in lower storage reservoir; In upper storage reservoir, add again seawater, re-distillation;
In 1 year, first step carries out in the winter time, carries out the solar distilling seawater operation in second step all the other seasons.
