Concentrate salt solution fluid valve 18 and be connected with concentrated brine tank 16, fresh water water discharging valve 19 is connected with fresh-water pool 17; Sun power blacking heat absorption concentrates brine tank 16, sun power blacking heat absorption fresh-water pool 17 is a solar radiation thermal energy collecting tank.
The workflow of the utility model gas-liquid mixed high speed evaporation desalination device is: at first opening pressure inlet valve 1 constantly injects at a high speed to inject in water storage box 2 bodies by pressure water inlet pipe pipeline and has passed through pretreated Mare Frigoris water, the power switch of opening pressure water pump 3, when the operating pressure of pressure water pump 3 has reached the high pressure that the difference of certain needed different finished product water quality requires, open long-range turboblower 7[or fan 7] power switch, opening pressure transfusion valve 4 passes through atomizing nozzle 6 to hurricane cover 5 body inner high voltage high-velocity jet mist droplets then, the highdensity air draught of flood tide enters the back from the gas inlet end 21 of hurricane cover 5 to be mixed with high-voltage high-speed seawater particulate droplet spray beam, when high pressure sea water particulate injection fluid ejects atomizing nozzle 6 with high-voltage high-speed, produce low pressure in the mixing section 8, suck the slow slightly air draught body of flow velocity, make with the particulate droplet and mix mutually, together enter scatterer 9, through scatterer 9 time, the pressure of mixed stream rises again gradually, mist droplet mix with air draught more evenly after carrying out two-way dissolving each other, form liquid-vapor mixture 10, spray outside the scatterer 9 at a high speed then, spray to aerial high-speed from mixture outlet end 22, further carrying out two-way dissolved each other more simultaneously, vaporized by rapid evaporation.
Liquid-vapor mixture 10 ejects the back and is forming the short grained while rapid absorption a large amount of heat on every side that suspends, tens times of rapid expansion, hundreds of times.Because fresh water water liquid expands easily, little droplet forms the mist cloud after expansion.The particle of the little droplet of fresh water that is easier to the easy carburation by evaporation of evaporable component is less than fine particle, volume is bigger, proportion is less, longer at the stroke that is sprayed the drift of conveying back by high velocity air, long for a long time distance ground suspends to drift about and descends slowly, form fine aerosol mist cloud particle, under the hot high temperature of transparent vaporization booth 11 intravital solar radiations, vaporized by rapid evaporation; Be not easy the evaporable component and be difficult for that the big particle of particle of concentrated salt solution small droplets of carburation by evaporation is big, volume is less, proportion is bigger, shorter at the stroke that is sprayed conveying back drift by high velocity air, suspending, the time of drifting about, weak point decline was very fast, form fine drop under the hot high temperature of transparent vaporization booth 11 intravital solar radiations, carburation by evaporation falls comparatively fast more slowly.The little droplet of seawater water liquid is by the high-voltage high-speed jet beam of pressure water pump 3 and long-range turboblower 7[or fan 7] the quick air-flow high density gas of huge injection air airshed constantly stir long distance ground for a long time and carry, the suspension drift of for a long time long distance, forming the little droplet of fine suspension is constantly assimilated by the air draught of flood tide, operation is constantly risen, constantly by the hot high temperature rapid evaporation vaporization of transparent vaporization booth 11 intravital solar radiations.
The little droplet of a large amount of suspensions is at long-range turboblower 7[or fan 7] the long for a long time distance ground of huge jet-stream wind fast spray carry under, the little droplet of a large amount of suspensions is at long-range turboblower 7[or fan 7] the long for a long time stroke ground of huge jet-stream wind fast spray to carry under, when constantly slowly descending, open the long-range turboblower 25[of single or multiple relay forms of relay form or the fan 25 of relay form this moment], the long-range turboblower 25[of single or multiple relay forms or the fan 25 of relay form] the quick air draught of the flood tide that produces will be a large amount of slowly the little droplet subparticle of suspension that descends gradually of drift blow afloat once more and be sent to the aerial Cheng Yunhang of long journey fast and drift about, constantly stirring and segregation is isolated, force the little droplet of fine suspension all to stir in the transparent vaporization booth 11 intravital aerial drifts that suspend for a long time, form suspension liquid-vapor mixture 10 after constantly mixing fully repeatedly for a long time with a large amount of air gas, suspension liquid-vapor mixture 10 is easy to be assimilated by air, and it is constantly vaporized by the high temperature rapid evaporation.At this moment, automatic vent window 15 in the variation constantly according to air pressure, is constantly transferred out behind transparent vaporization booth 11 intravital a large amount of unnecessary gas accumulations automatically fast.Because it is shorter to concentrate the time that the salt solution small droplets stops aloft, the stroke of the drift that suspends is shorter, and it is very fast to descend, and under the separation of interval division board 12, is collected in the concentrated brine tank 16 of sun power blacking heat absorption; Stroke long, the drift that suspends is longer the time of being detained because the fine little droplet of fresh water aloft suspends; It is slower to descend, and under the separation of interval division board 12, is collected in the fresh-water pool 17 of sun power blacking heat absorption.Transparent vaporization booth 11 is under the boosting effect of high-efficiency solar, the fine suspension liquid-vapor mixture 10 that the trip that stagnates is in the air paced up and down carries out the rapid evaporation vaporization, the quick mobile water flow of flood tide is carrying the little droplet of a large amount of suspensions and is moving rising simultaneously, after part subparticle wherein is evaporated the vaporization rising, the hypogene water steam flow of part enters in the vaporizing chamber 14 on upper strata from the blinds fenestra of the transparent window shutter interlayer board 13 of single admission, through evaporation vapour, change and compile back formation distilled water again.At last, open and concentrate salt solution fluid valve 18, will concentrate salt solution water liquid and constantly discharge; Open fresh water water discharging valve 19, fresh water water liquid is constantly discharged; Open distilled water flowing water Valve 20, distilled water water liquid is constantly discharged; Reach that low power consuming, volume great disparity is poor, proportion greatly different poor, suspension drift stroke great disparity is poor, the residence time great disparity that suspends is poor, grow for a long time apart from separation and grow purpose apart from isolated gas-liquid mixed high speed evaporation desalination.
