The specific embodiment
The device of (seeing Fig. 4 and Fig. 5) the utility model mainly comprises the hull 1 that can in water, float, and sets gradually lower storage reservoir 2, upper storage reservoir 3, printing opacity canopy 4 in the hull; At the bottom of the 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 the distillation tank is communicated with lower storage reservoir through distillation water channel 33; An anchor ring 11 is fixed in the hull bottom, and anchor ring can connection cable 12 and anchor (not scheming), can make hull be docked in a certain marine site like this, particularly can be docked in the zone of high-quality seawater.
Be provided with blockage mechanism in the upper storage reservoir 3, blockage mechanism comprises spring 34, kickboard 35, stay cord 36, the stopper 37 that links to each other successively, and an end of its medi-spring is fixed on upper storage reservoir, and the other end is pressed on the kickboard; Stopper is blocked drainage hole by deadweight, and when kickboard overcame spring force and makes progress, through soft stay cord, the pull-up stopper broke away from drainage hole;
Printing opacity canopy 4 is provided with vent window 41 and canopy lid 42 (seeing Fig. 2 and Fig. 3), and the canopy lid can move and the enclosed ventilation mouth, and upper storage reservoir is isolated from the outside;
Be provided with water-accepting basin 5 in the lower storage reservoir 2, be provided with pulley 25 and stay cord 26 in the pulley groove 24 of water-accepting basin bottom and lower storage reservoir, an end of stay cord is fixed on lower storage reservoir 2 tops; The other end links to each other with canopy lid 42; After water-accepting basin filled water, under the effect of water gravity, water-accepting basin passed through pulley; The pulling stay cord moves and the enclosed ventilation mouth canopy lid;
Upper storage reservoir is provided with breather pipe 61 (see figure 5)s that are fixed at the bottom of the pond, and an end of breather pipe is higher than distillation tank 32, and the other end stretches into lower storage reservoir 2;
Use said apparatus and make the step of fresh water:
First step: be lower than the time below 0 ℃ closing on temperature, remove canopy lid 42, expose vent window 41, and in upper storage reservoir 3, add seawater (using the water pump operation usually), the lower plane of the height of seawater to kickboard 35 (see figure 4) that is as the criterion.Be lower than the time below 0 ℃ at temperature, the seawater in the upper storage reservoir freezes in cold air, and (when freezing, the salt in the seawater can be discharged from outside ice crystal.But still have some salts to have little time to discharge the ice sheet that freezes rapidly, when these some salts need that ice sheet begins to melt afterwards, at first discharge ice sheet with the water that melts the slit between ice crystal).When ice is tied certain thickness, expand because ice body is long-pending, promote kickboard 35, overcome spring force upwards, through soft stay cord 36, stopper 37 is pulled up, and the seawater that does not freeze flows into water-accepting basin 5 and lower storage reservoir 2 (see figure 6)s from drainage hole 31;
After the water of water-accepting basin 5 filled, under the water action of gravity, water-accepting basin canopy lid 42 is moved and enclosed ventilation mouth 41, so that upper storage reservoir 3 was isolated from the outside through pulley 25 pulling stay cords 26; After this, owing to no longer need water gravity to work, the seawater in the water-accepting basin can slowly spill from aperture 51, up to having leaked.
(see figure 5) sunlight sees through printing opacity canopy 4, and the air in the heating printing opacity canopy is in order to melt ice; Because the hot air in the hot pressing effect, canopy flows into the ice sheet bottom through breather pipe 61, also in order to melt ice; Salty frozen water in the ice releases from the ice crystal gap gradually, flows into lower storage reservoir 2 through drainage hole 31; Afterwards, ice sheet melts gradually, and kickboard 35 is descended by the compressing of spring 34 gradually, and stopper 37 also descends thereupon;
When ice sheet is thinned to a certain degree through thawing; The salinity of the salty frozen water of particularly discharging when the time comes is less than after 1 ‰ (the saliferous standards of fresh water); Stopper is blocked drainage hole fully by deadweight, and (this operating mode can be confirmed through the length of adjustment stay cord 36; After the salty frozen water salinity of discharging is less than 1 ‰, guarantee that the length of stay cord 36 can let stopper block drainage hole 31.The length of stay cord can keep permanent use after once confirming).After this, the ice in the upper storage reservoir continues to melt, and turns to fresh water;
Ice in upper storage reservoir all turns to fresh water;
Second step: take out the fresh water in the upper storage reservoir 3; Concentrated seawater in the lower storage reservoir 2 is also taken out, pump into seawater flushing lower storage reservoir and drip tray one time afterwards, to dilute the salinity of residual concentrated seawater.Pump the seawater of this flushing then, the drainage hole 31 of upper storage reservoir and the aperture 51 of drip tray are blocked; Get into 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 the heating upper storage reservoir; The upper storage reservoir pool wall can be established adiabatic layer insulation, and surperficial blacking is beneficial to heat absorption) make evaporation of seawater, water vapour rises; Because printing opacity canopy itself heat absorption is few, temperature is lower than warm water in the pond, and water vapour is met cold on printing opacity canopy 4, condenses into water droplet, drops down along the inclined-plane of printing opacity canopy, falls into distillation tank 32, through distill water channel 33 inflow lower storage reservoirs 2 (drip tray 5 floats) in the aqua distillata of lower storage reservoir.Though the aqua distillata in the lower storage reservoir can be sneaked into seawater salinity residual in the 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 aqua distillata in the lower storage reservoir; In upper storage reservoir, add seawater again, again 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.
