Description

Deflation isolator for ultrahigh-speed seawater desalination

The present invention relates to seawater and desalinate at a high speed and the quick salt manufacturing of salt water, especially the deflation isolator for ultrahigh-speed seawater desalination of forming by cap valve, explosion chamber, high-temperature chamber, heating net, sealing coat check valve, cooling room, spiral coil cooling tube, water pump etc. in heating container high-duty boiler, lighter for ignition, cylindrical shell, explosive, cover valve, the boiler.

The method for desalting seawater that adopts both at home and abroad is many at present, covert method: method of evaporation, distillation method, method of cooling; Membrane separation process: reverse osmosis method, electroosmose process: chemical equilibrium method: main three major types type such as ion exchange method, hydration method, solvent extration, at present state-of-the-art also is to use maximum to be to dodge anxious distillation method, to account 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.(need carry out the repetition more piece and dodge and to heat up in a steamer, reached at present need again and again repeat to dodge heat up in a steamer operation 30 more pieces/time, the huge efficient of equipment is humble).Its shortcoming is: facility investment is many, 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 deflation isolator for ultrahigh-speed seawater desalination, it is simple in structure, less investment, stable performance, volume is little, incrustation scale is few, easy to use, system water express train, go out fresh water amount very high (approximately 95% fresh water, only produce about 5% strong brine).

In order to achieve the above object, solution of the present invention is: utilize salt quasi-molecule in the seawater all not participate in this characteristic of carburation by evaporation process, adopt explosive in seawater, to put quick-fried, blast discharges huge energy and produces a large amount of high temperature, high pressure, high-speed gas impacts and decomposes seawater, make seawater expansion atomizing form hanging drop, water liquid is long-pending sharply to become manyfold to increase, proportion becomes manyfold to alleviate rapidly, make its vapour, the difference in specific gravity of liquid is apart from widening manyfold, through high temperature, high pressure, high velocity air impacts the mixed solution of isolating and isolating different specific weight in moment, import the pipe cooling condensation that is cooled in the cooling room and become fresh water, adopt vapour to separate the purpose that reaches the ultra-high speed sea water desaltination with the difference in specific gravity of liquid.

Seawater fresh water molecule in high temperature volatilizees easily, and proportion, a distance change bigger; The salt quasi-molecule is difficult for volatilization, and proportion, a distance change less.Adopt under the prerequisite of seawater comprehensive boiling vaporization in High Temperature High Pressure, (seawater is in high-boiling, and 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 the salt quasi-molecule is difficult for by high-temperature evaporation.) explode in seawater with explosive, mixed solution is discharged huge energy by explosion and produces a large amount of high temperature, high pressure gas high speed impact decomposition atomizing, water liquid sharply expands in moment, intermolecular impact force sharply increases, high temperature, high pressure, high velocity air break through gap between the mixed solution water molecules with the pressure pressure that surpasses the external atmosphere pressure manyfold, high temperature, high pressure, high velocity air are fallen over each other and are squeezed outward, drop is swollen at once in all directions come, intermolecular distance becomes manyfold to increase the rapid diffusion of expanding of the vaporific steam of formation (hanging drop).Salt molecular water liquid owing to be difficult for is evaporated the particle drop that vaporization forms maximum particle and is got farthest by ram-jet.Reach the difference in specific gravity that enlarges to greatest extent between salt quasi-molecule and the fresh water molecule, vapour, liquid separate under the effect of high speed impact power, make the particle strong brine of its proportion maximum be injected in outermost, reach to separate purpose and will keep apart in their moments.

Technical scheme of the present invention is as follows: cap valve in pre-hot sea water transport pipe water-in, high pressure gas transport pipe inlet mouth, lighter for ignition, cylindrical shell, explosive, (can adopt the explosive of nontoxic pollution-free, explosive is positioned in the cylindrical shell) cover valve, well heater, the boiler is set in filling with the closed high-duty boiler of seawater; Explosion chamber is large-scale closed container, water liquid is fully vaporized enlarge the stereoscopic and omnibearing generating surface to greatest extent, and built-in high-duty boiler and high-temperature chamber connect; The built-in multilayer heating net of high-temperature chamber, sealing coat check valve gas, liquid discharge orifice externally are provided with high temperature mixed solution discharge tube and are communicated with water pump; Heating net is the layer stereo network, and the heating back can form high-density high temperature air filtration layer when water liquid passes through; It is the high air-sensitive induction time-delay auto-closing switch one-way cock of only export but no import that the sealing coat check valve can adopt the magnetic valve working forms; Gas, liquid discharge orifice are for discharging a large amount of unnecessary gas and the discharge orifice of strong brine; 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 that high temperature mixed solution admission port is communicated with water pump, another hole is pre-hot sea water 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 deflation isolator for ultrahigh-speed seawater desalination is: 1, heating of Mare Frigoris water and explosive charge, open Mare Frigoris water water intaking valve earlier, with Mare Frigoris water in the seawater pond replenish liquid by the water pump force feed to the built-in water-cooled tube of quick cooling chamber, because the overlapping snakelike water-cooled tube of multilayer is immersed in the cooling room of filling the high temperature mixed solution, can obtain from bottom to top preheating step by step (water temperature Yue Keda is more than 90 degrees centigrade), open again at the pre-hot sea water inlet valve of the high-duty boiler that is equipped with explosive and import in the pressure kettle body of heater, when the preheating sea level fluctuations reaches about 80% water level, switch and boiler preheating seawater water inlet valve of switching off the pump simultaneously and Mare Frigoris water inlet valve.Open the air compressor power source of high-duty boiler and the thermal source switch pressurized, heated of heat hot source switch and heating net simultaneously, when the vaporization of seething with excitement of the intravital High Temperature High Pressure seawater of high-duty boiler comprehensively, can put blast by opening point firearm fired charge (explosive is positioned in the cylindrical shell), the mixed solution of High Temperature High Pressure discharges huge energy and produces a large amount of high temperature in by moment, high pressure, high-speed gas is decomposed the hop states of matter by high speed impact in explosion chamber changes, make the sharply diffusion of hot gas wave that discharges huge energy, make water liquid form the expansion of vaporific steam (hanging drop) high-density and spread apart, form larger particles drop (the salt quasi-molecule does not all participate in the carburation by evaporation process) after salt molecular water liquid is hit.Sea water mixing liquid sharply expands between in an instant, and volume becomes manyfold growth, proportion to become manyfold to alleviate rapidly rapidly.Multilayer heating net heating back forms high-density high temperature air filtration layer, can stop steam in moment, steam by the time increase that resistance slows down the logical out of date travelling speed of steam and with the vaporific steam selected difference in specific gravity of high-temperature gasification repeatedly once more.(when separating in moment, the room temperature of high-temperature chamber remains on more than the comparatively high temps, and isolating material is basically: strong brine or saline crystallization body and vaporific steam, difference in specific gravity are easy to obtain separate apart from widening manyfold).Enlarge difference in specific gravity and travelling speed between fresh water molecule and the salt quasi-molecule to greatest extent.(in a single day broken away from water body between fresh water molecule and the salt quasi-molecule, just no longer produced reactive force each other.) formed the larger particles drop because strong brine is difficult by high temperature, high pressure, high-speed gas carburation by evaporation, the impact forces maximum operational speed that affords is the fastest, keeps apart when being injected in outermost by sealing coat check valve auto-closing as the particle strong brine of proportion maximum (a large amount of unnecessary gas and strong brine or saline crystallization body are excreted).Can close high-duty boiler heating source, high pressure gas propulsion source, heating net heating source, boiler inner cap valve switch this moment simultaneously.

2, produce fresh water: open high-temperature chamber body bottom high temperature mixed solution fluid valve earlier, allow the high temperature mixed solution pour in the 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 into fresh water.After the intravital high temperature mixed solution of high-temperature chamber is all discharged, the switch that promptly switches off the pump simultaneously, mixture export valve switch, draining fresh water valve switch.Circulation repeatedly so constantly.

Owing to adopted fired charge blast vapour in the above-mentioned solution, the liquor ratio method of double differences is separated method for desalting seawater, only need with seawater be placed in the boiler pressurized, heated boiling vaporization then igniting put blast, cause sea water mixing liquid to be released out huge energy and produce a large amount of high temperature, high pressure, the gas high speed impact is decomposed to form the vaporific steam hanging drop of high-density, intermolecular distance sharply becomes manyfold to strengthen, water liquid is long-pending to become manyfold growth proportion to become manyfold to alleviate rapidly rapidly, make between fresh water molecule and the salt quasi-molecule to produce maximum water and vapour difference in specific gravity, then under the high speed impact reactive force strong brine ejected external in moment, isolate vaporific steam and strong brine (or saline crystallization body) and with their moments in keep apart.It is simple in structure, less investment, stable performance, volume are little, system water express train, incrustation scale few (and being convenient to remove), to go out fresh water yield high especially, and (being particularly suitable for the concentrated seawater desalination) can save a large amount of energy and time.(evaporation of water body can only be carried out at liquid-gas interface, because water body can not evaporate in inside, has determined to be a kind of slow evaporated liquid, and can not volatilize rapidly).Keeping apart of fresh water in the separating of the fresh water of method for desalting seawater of the present invention from explosive charge, seawater and strong brine or saline crystallization body, the seawater and strong brine or saline crystallization body, whole process was finished in 1 second.Than the present a large amount of solar desalination process in application still, its system water speed improves tens thousand of times, and the enrichment factor that reaches the purpose of ultra-high speed sea water desaltination and system water is very high.(be very easy to accomplish: injection be seawater, what produce in moment is a large amount of fresh water and saline crystallization bodies.)

The present invention is further described with embodiment below in conjunction with accompanying drawing one.

Accompanying drawing one is in the high-duty boiler of deflation isolator for ultrahigh-speed seawater desalination of the embodiment of the invention, explosion chamber, high-temperature chamber, quick cooling chamber principle of work simplified diagram.

A kind of deflation isolator for ultrahigh-speed seawater desalination of the present invention is shown in accompanying drawing one, opening valve (4), valve (7) opens water pump (3) seawater (2) in seawater pond (1) is pressed in the overlapping spiral coil cooling tube of multilayer (5), because cooling tube (5) is positioned in the immersion liquid of filling high temperature mixed solution (21) in the quick cooling chamber (6), makes Mare Frigoris water (2) obtain importing after from bottom to top the preheating and be equipped with in heating container high-duty boiler (8) body of explosive (12).When the injection of pre-hot sea water (2) had reached in boiler (8) body about 80% water level, (3) valve-off (4), valve (7) simultaneously can switch off the pump.The heating source switch pressurized, heated vaporization of the heating net (17) in pressurized source (25), heating source (14) and the high-temperature chamber (16) of unlatching high-duty boiler (8).After water liquid seethes with excitement fully, be that opening point firearm (10) fired charge (12) explosive (12) is positioned in the inherent seawater of cylindrical shell (11) and puts blast, make and discharge a large amount of high temperature of huge energy generation in moment, high pressure, high velocity air backs down cap valve (9) in cover valve (13) boiler, water liquid in explosion chamber (15) by high temperature, high pressure, the impact branch of high velocity air is taken off rapid expansion and is outwards diffuseed to form vaporific steam hanging drop rapidly, distance becomes the increase of manyfold between between the water liquid molecule, and volume becomes the growth of manyfold rapidly, proportion becomes alleviating of manyfold rapidly.Steam is by the built-in multilayer heating net (17) of high-temperature chamber (16) time, heating net (17) be heated the back form high-density high temperature air filtration layer (can steam by the time stop steam, increase resistance and slow down the logical out of date travelling speed of steam), make vaporific steam be subjected to the selected difference in specific gravity of gasification repeatedly of high-temperature gas once more, enlarge the difference in specific gravity of vapour, liquid between fresh water molecule and the salt quasi-molecule to greatest extent.Because the particle strong brine of proportion maximum is difficult for being vaporized, form the largest particle drop, the particle strong brine that makes the fastest proportion maximum of these travelling speed to outermost, is reached the separation purpose of required vapour, the liquor ratio method of double differences by high temperature, high pressure, high velocity air ram-jet.When high temperature, high pressure, high velocity air back down sealing coat check valve (18), a large amount of unnecessary gas and strong brine (or saline crystallization body) are ejected external from gas, liquid discharge orifice (24), make vapour, liquid separation and isolated in moment in effect following moment of sealing coat check valve (18) during auto-closing.Promptly close interior cap valve (9) switch of heating source switch boiler of heating source (14), high pressure gas propulsion source (25) switch and the multilayer heating net (17) of boiler (8) simultaneously.In case after opening the valve switch unlatching water pump (20) of valve (19), valve (22), high temperature mixed solution (21) is promptly poured in the cooling room (6), the overlapping spiral coil cooling tube of multilayer (5) in quick cooling chamber (6) cooling fast condenses, and fresh water (23) i.e. is the batch output.After the high temperature mixed solution (21) in the high-temperature chamber (16) has been discharged, can switch off the pump simultaneously (20), valve (19), valve (22) switch.So constantly circulation repeatedly.
