The method for desalting seawater of home and abroad employing at present is many, covert method: method of evaporation, distillation method, method of cooling; Membrane separation process: reverse osmosis method, electroosmose process; The chemical equilibrium method: main three major types type such as ion exchange method, hydration method, solvent extration, using maximum at present is to dodge anxious distillation method, accounts for 70% of world today's sea water desaltination ultimate production.
Dodging anxious distillation method is exactly to utilize the boiling point of water to reduce this characteristic with pressure, seawater is heated in pipeline, guide to then in the lower evaporator room of pressure, the high temperature seawater that is introduced into will evaporate rapidly between in an instant, and the steam of generation obtains condensation and causes fresh water outside the pipeline that Mare Frigoris water is housed.Its shortcoming is: equipment is huge, and the seawater internal circulating load is big, the system water yield is little, the low process cost of enrichment factor is higher.(need large batch of seawater to make, get only 1 part of fresh water, but will produce 9 parts of concentrated seawaters that pollution is arranged).
The purpose of this invention is to provide a kind of centrifugal isolator for efficient seawater desalination, it is simple in structure, less investment, stable performance, incrustation scale are few, easy to use, power consumption seldom, water outlet is fast, cost is low, go out fresh water amount very high (9 parts of fresh water, only produce 1 part of strong brine).
In order to achieve the above object, solution of the present invention is: utilize seawater flash deflation (blast) under High Temperature High Pressure, the mixed solution aerosolization of sharply expanding, the volume characteristic that proportion alleviates rapidly at double that is multiplied rapidly adopts difference in specific gravity centrifugal force vapor-liquid separation to reach efficient desalination purpose.Seawater fresh water molecule in High Temperature High Pressure volatilizees easily, and proportion, a distance change bigger; Molecules of salt is not volatile, and proportion, a distance change less.Under the seawater prerequisite that boiling is vaporized comprehensively in High Temperature High Pressure in the high speed rotating of ultra-high speed whizzer, (seawater is in the High Temperature High Pressure boiling, the fresh water molecule is owing to containing more volatile components, so change very greatly with proportion along with the rising water liquid of temperature is long-pending by high-temperature evaporation easily; It is owing to containing more difficult volatiles, so change very little along with the rising water liquid of temperature is long-pending with proportion that molecules of salt is difficult for by high-temperature evaporation.) behind the flash deflation (blast), the huge energy pressure gas aerosolization that mixed solution is discharged by explosion, moment, gas sharply expanded, intermolecular impact force increases, high temperature and high pressure gas breaks through gap between the mixed solution water molecules with the pressure that surpasses the external atmosphere pressure manyfold, high temperature and high pressure gas is fallen over each other and is squeezed outward, drop is swollen at once in all directions come, and intermolecular distance becomes several times to strengthen sharply diffusion of formation mist steam (hanging drop).Salt quasi-molecule liquid is owing to be difficult for being vaporized the bigger particle of formation.Reach the difference in specific gravity that enlarges to greatest extent between salt quasi-molecule and the fresh water molecule, vapor-liquid separation under the effect of ultra-high speed centrifugal force gravity, the distribution of particles that makes its proportion maximum is in the periphery, and the particle of proportion minimum is near turning axle, reaches to separate purpose and their moments are kept apart.In heating container pressure kettle body of heater, inject the quick pressurized, heated vaporization of the laggard row of pre-hot sea water, centrifugal chamber is placed in employing ultra-high speed centrifugal force rotation on the ultra-high speed whizzer, cap valve flash deflation (blast) in opening boiler, make the high temperature and high pressure gas in its mixed solution discharge huge energy between in an instant, the hot gas wave sharply diffuse volumetric proportion that is multiplied rapidly alleviates rapidly at double.Isolate different proportion gas-liquids, sealing coat check valve moment is set in the centrifugal chamber body isolates different proportion gas-liquids, the lighter mixing gas-liquid of proportion of separator well is transported in the quick cooling chamber, and being cooled off fast to condense by the overlapping spiral coil cooling tube of settling in the quick cooling chamber of the multilayer of filling with Mare Frigoris water promptly becomes fresh water.Peripheral bottom at centrifugal chamber is provided with the strong brine discharge outlet.So constantly circulation repeatedly.
Technical scheme of the present invention is as follows: the closed high-duty boiler is made up of two parts, and top is provided with pre-hot sea water transport pipe water-in, and the bottom is provided with in the boiler cap valve and is connected with the decompression explosion chamber and is equipped with high pressure admission mouth and water level displaying tube; Explosion chamber is large-scale closed container, be 10 times that boiler holds body approximately, water liquid is fully gasified, in establish one or more layers heating net (can form the high temperature air filtration layer) top and be connected with high-duty boiler, the bottom is connected with the high speed centrifugation chamber, the sealing coat check valve is set in the centrifugal chamber, externally high temperature mixed solution discharge outlet is set and is communicated with water pump, peripheral bottom is provided with the strong brine discharge outlet; It is the high air-sensitive delay-self-closing switch one-way cock of only export but no import that the sealing coat check valve can adopt the magnetic valve working forms; The ultra-high speed whizzer is a ultra-high speed stereoscopic built-up type special centrifugal machine; Quick cooling chamber is that the closed built-in overlapping spiral coil cooling tube of multilayer of filling with Mare Frigoris water is convenient to quick cooling, cooling room top is provided with two apertures, one aperture is a high temperature mixed solution admission port, another hole is a preheating water pipe water outlet, the bottom also is provided with two apertures, one hole is the fresh water water outlet, and another hole replenishes the liquid import for Mare Frigoris water and is communicated with water pump.
The workflow of centrifugal isolator for efficient seawater desalination is; 1. Mare Frigoris water heating: open Mare Frigoris water water intaking valve earlier, Mare Frigoris water in the seawater pond is replenished liquid to be delivered in the water-cooled tube of quick cooling chamber bottom by water pump, because the overlapping snakelike water-cooled tube of multilayer soaks and is embedded in the cooling room of filling the high temperature mixed solution, can obtain from bottom to top preheating step by step, import again in the pressure kettle body of heater, when reaching about 70% water level, the preheating sea level fluctuations (shows) switch and boiler preheating seawater water inlet valve of switching off the pump and Mare Frigoris water inlet valve by water level displaying tube.The power system of ultra-high speed whizzer can be opened, inferior high-duty boiler pneumatic press and the thermal source switch pressurized, heated opened, whizzer begins to do the centrifugal body rotation speed of rotation of getting rid of and accelerates gradually, the intravital High Temperature High Pressure seawater of the high-duty boiler vaporization of comprehensively seething with excitement when whizzer reaches maximum speed, can open cap valve in the boiler, flash deflation (blast), the mixed solution of High Temperature High Pressure is being impacted the variation of hop states of matter by the High Voltage gas of abrupt release huge energy in explosion chamber, make it to discharge the impact of beta maximum energy hot gas wave water liquid formation mist steam (hanging drop) high-density is spread apart, salt quasi-molecule liquid is hit and forms the larger particles drop.Sea water mixing liquid expands rapidly between in an instant, the volume proportion that is multiplied rapidly alleviates rapidly at double, add thermosetting high temperature air filtration layer with the vaporific steam selected difference in specific gravity that gasifies once more by one or more layers heating net, enlarge the difference in specific gravity between fresh water molecule and the molecules of salt to greatest extent, under the effect of ultra-high speed centrifugal force gravity, since strong brine be difficult for by high-temperature evaporation (stressed maximum is run the most soon) as the big distribution of particles of weight/power ratio keep apart when valve moment closure (delay time approximately 1 second auto-closing) at peripheral coverlet (segregate strong brine amount with account for by insulated chamber spatial 70%, account for the boiler seawater injection 1%); The particle steam of proportion minimum is kept apart during also by the check valve closure near turning axle.Can close ultra-high speed whizzer propulsion source and high-duty boiler thermal source this moment simultaneously, stops the rotation until whizzer.
2. produce fresh water: open centrifugal chamber bottom high temperature mixture fluid valve earlier, allow the high temperature mixed solution pour in quick cooling chamber, inferiorly open the fresh water flowing water Valve and pump switch discharges water, when the high temperature mixed solution in a single day enter quick cooling chamber just be cooled in the overlapping spiral coil cooling tube of multilayer of indoor arrangement a large amount of Mare Frigoris water fast cooling condense and be converted into fresh water.After the intravital high temperature mixed solution of centrifugal chamber is all discharged, promptly switch off the pump switch and high temperature mixture export valve switch and discharging fresh water valve switch are opened centrifugal chamber peripheral bottom valve switch at last and are opened sealing coat check valve switch discharging strong brine after a while again.So constantly move in endless cycles repeatedly.
Owing to adopted in the above-mentioned solution and put the sea water desaltination of quick-fried difference in specific gravity vapor-liquid separation method, flash deflation (blast) causes sea water mixing liquid quilt to impact into high-density mist steam hanging drop at the high temperature and high pressure gas that abrupt release is gone out huge energy only to need to vaporize seawater pressurized, heated boiling in the rotation of ultra-high speed whizzer then, rise to propagation sharply diffusion everywhere suddenly, intermolecular distance becomes several times to strengthen, the long-pending proportion that is multiplied rapidly of water liquid alleviates at double, make between fresh water molecule and the molecules of salt to produce maximum difference in specific gravity, isolate fresh water and strong brine with the ultra-high speed whizzer then and their moments are kept apart.It is simple in structure, less investment, stable performance, power consumption seldom, system water express train, incrustation scale few (and being convenient to remove), cost be low, it is high especially to go out fresh water yield, (being particularly suitable for the concentrated seawater desalination) can use in various fields.Really accomplish what the nearly one thousand years people looked forward to always: cost is low, equipment is simple, cheap, the popular sea water desalinating plant of popularizing in an all-round way that output is very high.
The present invention is further described with embodiment below in conjunction with accompanying drawing one, accompanying drawing two.
