Description
Technical field
The present invention relates to field of sea water desalting technology, specifically, relate to a kind of low-energy consumption normal-temperature seawater desalinating system and method thereof of under vacuum or negative pressure state, carrying out.
Background technology
The area of earth surface 2/3 is awash, but water reserve 97% is seawater and brackish water, and these water are very abundant.But, utilize seawater must pass through desalination.At present, the whole world has more than 120 countries and regions to adopt seawater or technique of desalinating saline water to obtain fresh water.According to statistics, seawater desalination system and turnout are increasing with annual speed more than 10%.Asian countries is as Japan, Singapore, Korea S, Indonesia and China etc. also develop activelies or use sea water desaltination as alternative water source all, with the quantity of increase from the main suit.
At present, the technology of sea water desaltination mainly contain distillation, freeze, way such as reverse osmosis, ion migration, chemical method.Existing desalination technology power consumption power consumption, though significant, with regard to present economic and technique level, Cost of seawater desalination is still than higher, and complex process, investment cost is big.
Below present desalination technology is simply introduced:
The simplest method is exactly a distillation method, with water evaporation and salt stays, is liquid fresh water with water vapor condensation again.
The method of another sea water desaltination is a cold method, and freezing seawater makes it icing, and when liquid fresh water became solid-state ice, salt is separated went out.Two kinds of methods all have the disadvantage that is difficult to overcome.Though distillation method is simple, can consume a large amount of energy, and produces a large amount of throw outs (mineral substance of salt in the seawater) in container, the fresh water that obtains on the contrary is but also few.Cold method will consume many energy equally, and the fresh water that obtains but taste is not good, is difficult to use.
To the middle of last century, a kind of new sea water desaltination mode has been come out, Here it is reverse osmosis method.This method utilizes semi-permeable membranes to reach fresh water and the isolating purpose of salt.Under normal conditions, semi-permeable membranes allows the solvent in the solution to pass through, and does not allow solute to see through.Because seawater saliferous height, if with semi-permeable membranes seawater and freshwater is separated, fresh water can be diffused into a side of seawater by semi-permeable membranes, thereby the liquid level of seawater one side is raise, and produces pressure up to certain height, and fresh water is no longer spread.This process is infiltration.If act in a diametrically opposite way, obtain fresh water, as long as the seawater in the semi-permeable membranes is pressed, the fresh water in the seawater is penetrated into outside the semi-permeable membranes, and the salt tunicle is blocked in the seawater.Here it is reverse osmosis method.This method subject matter is that semi-permeable membranes is stopped up by the foreign matter in the water body easily.
Now, people also improve traditional distillation method.Usually, water will be heated to 100 ℃ of just boilings at normal temperatures and pressures, produces a large amount of water vapour.Traditional distillation method has only considered to obtain by elevated temperature the mode of water vapour, and it is very huge to consume energy.And new method is that air pressure is lowered, and the seawater through suitably heating, sends in the synthetical vacuum distilling chamber, and the fresh water in the seawater can evaporate rapidly in moment, all became water vapour.Many such vacuum distilling chambers couple together, and have just formed large-scale desalinator.Desalinize seawater at this novel distillation method, many people have proposed the technical scheme of oneself.
See that Chinese patent application number is: 98208392.0 Chinese utility model patent specification sheets, it discloses a kind of " negative pressure evaporation formula sea water desalinating plant ".It mainly is made up of desalination jar, vacuum pump and fresh water container, and the desalination jar comprises tank body and loam cake; Tank body open topped, its inner chamber are equiped with the tabular net of plurality of vertical, and it has the suction tube that is communicated with vacuum pump by upper tube wall, and there is the salt-extracting door of the sealing that can open and close its lower end; Loam cake has the sandwich structure of cavity, and there is water inlet pipe on last top, is distributed with some weep pipes on the following baseplane, and loam cake is lined with Gask-O-Seal with bottom surface flange and tank body end face companion flange limit, becomes sealing to be fastenedly connected with bolt and nut; The utility model adopts the vacuum pump suction to produce negative pressure and makes evaporation of seawater, and simple in structure, equipment is changeable, and sea water desaltination speed is fast, and desalinating cost is lower.
Above-mentioned utilization vacuumizes or negative pressure, low-pressure state under vacuum desalinize seawater or though the technology of sewage has certain feasibility, but these technical schemes all are to extract the intravital steam of sealing continuously out with vacuum pump always, and the steam that vacuum pump is extracted out is condensed into fresh water again.Its problem that causes is exactly: 1, the energy consumption of vacuum pump own is very high, and vacuum pump is in running order always, needs to consume the bigger higher-grade energy such as electric energy.2, the pumping process of vacuum pump is to need lubricating oil and mix with the gas of extracting out, so a device that separates and reclaim lubricating oil is arranged on vacuum pump.If with its vapour that draws water, very fast vacuum pump will wear and tear and break down.
See that Chinese patent application number is: 98225969.7 Chinese utility model patent specification sheets, it discloses a kind of " vacuum pipe solar fresh-water generator ", also is to adopt same principle to carry out sea water desaltination to handle.In addition, see that Chinese patent application number is: 99244690.2 utility model patent also discloses " a kind of low-pressure distillation (evaporation) sea water desalinating plant ".
The problem of this class technology is not consider to be dissolved with a large amount of air in the water body, the air of constantly overflowing under negative pressure in the water source desalination process can not be continued or efficient extremely low, the temperature difference system that also has evaporation and condensation is imperfection also, and the feasibility of imagination, operability is relatively poor and complex structure, cost are higher.
