Two, background technology
Along with society to the increasing sharply of water resources demand, the desalination technology development in recent years is very fast.According to statistics, nineteen ninety-five global seawater and the desalination of brackish water handle based on distillation method, then distillation method accounted for 45% by 2005, reverse osmosis method accounts for 43%.In addition, electroosmose process, ultra-filtration method, biomembrance process etc. are all in develop and spread.
The advantage of reverse osmosis method is desalination efficient height, non-scaling, suitable scale operation.Shortcoming is, its high-level efficiency is kept by high pressure, needs the about 1000 * 101.33KPa of pressure as the desalination brackish water, and seawater then needs about 5500 * 101.33KPa.Obviously, high pressure high energy consumption then.In addition, the maintenance of high-tension apparatus and the routine cleaning of semi-permeable membranes and replacing, technical difficulty has more mostly improved production cost.
The advantage of distillation method is, technology is simple, and cost of equipment is lower, is suitable for scale operation.Shortcoming is that the energy consumption high efficiency is low, easily fouling.For preventing fouling, often require flow velocity to be not less than 2.5m/s, then cause the excessive invalid operation of seawater throughput, increased production cost.For this reason, in recent years, develop negative pressure and press the steam distillation method, seawater is desalinated under vacuum state, service temperature is lower than 70 ℃, has alleviated fouled condition, has improved product water efficient, has prolonged equipment life.U.S.'s patents of invention " desalting system " (Desalation system, Jnited Paten:4285776) etc., the sea water desaltination effect is better under negative pressure.Obviously the power consumption that vacuumizes has improved production cost again, is its shortcoming.
In known salt manufacturing (comprising salt and non-salt) technology, mainly be to shine method for making and decoction method.The former is long the cycle, is subjected to weather effect bigger, and site area is also big; Latter's energy consumption is big and crystal is less, and crystalline form is incomplete.Particularly salt-making process has lost most fresh water, is its disadvantage.
Three, summary of the invention
1, basic ideas
The technical spirit that the steaming method desalinizes seawater is heated up in a steamer in application, adds hot sea water, makes it salinity by the boiling vaporization and separates with hot steam, then hot steam is condensed into fresh water (distilled water).Obviously, the boiling vaporization is crucial.Using the technical spirit of shining method for making and decoction method's salt manufacturing is, adds hot sea water (brackish water) transpiring moisture, improves concentration, separates out salinity.Obviously, it is crucial improving concentration.In view of the above, thinking of the present invention is as follows.
(1) seawater gasification efficiency and temperature are proportionate.Temperature high-level efficiency more is also high more.When particularly reaching boiling point, it is most effective that ebullition, gasification takes place.Yet the temperature high energy consumption is also high, and the tank capacity fouling.
(2) seawater gasification efficiency and pressure are negative correlation.Pressure is inefficient more high more.This is that lower boiling is low more more because of pressure.Experiment showed, that boiling point is 100 ℃ when pressure is 101.33kPa (barometric point), when pressure was 4.2455kPa, boiling point was 30 ℃.Obviously, the boiling point less energy-consumption is also low, and the container non flouling behaviour that seethes with excitement at normal temperatures.
(3) be subjected to the enlightenment of famous evangelista torricelli experiment, change mercury into water,, then produce the Tuo Shi vacuum zone on the pipe top when the height of Tuo Shi pipe during greater than 10.33m.The steam that free expansion is arranged in the district.This moment, the water weight of 10.33m equaled an extraneous atmospheric pressure by force just.Because height 10.33m is the interior water of pipe and the boundary of steam, the present invention claims that temporarily 10.33m is critical high H.Equally, when the inverted-loop tube height that is full of seawater during greater than H, its pipe top also will produce the Tuo Shi vacuum zone.The seawater boiling point at critical high H place will greatly descend.So, in upper strata when heating of its left side seawater, must seethe with excitement at normal temperatures, the steam of hot sea water is raised to behind the vacuum zone to extraneous heat release, be condensed into distilled water and flow to the lower end on the free-water level of right side, and the salinity in the hot sea water is stayed in the pipe of left side.Thereby realized utilizing salt, the water sepn of natural energy (barometric point and earth gravity) under the normal temperature negative pressure, obtained freshwater product.
(4) in the seawater pipe of left side, along with the continuous effusion of steam, the salinity of surface water will increase gradually, compare with lower floor and just form concentration gradient, promptly form the distributional difference of molecule Gibbs free energy, so just produced diffusion.Make the upper strata salinity automatically move downwards, and can be attached to fouling on the tube wall.So, the salinity that spreads downwards automatically and is continuously concentrated in the pond, can improve concentration continuously,, separate out the salt crystalline substance until saturated supersaturation.Obviously, need not to heat with this method salt manufacturing.Thereby realized utilizing natural energy (molecule free energy) to improve concentration and obtained the salt product.
