Description
Technical field
The present invention relates to a kind of cross absorption solar energy wind energy desalting device for sea water, belong to the technical field of solar wind-energy sea water desaltination.
Background technology
Along with growth and the expanding economy of population in the world, the in short supply of land Freshwater resources extremely highlights, and caused the attention of many countries.A large amount of water resourcess is arranged in the seawater, is an effective way that solves the deficient crisis of Freshwater resources with sea water desaltination.Method for desalting seawater commonly used has distillation method, ion exchange method, electroosmose process, reverse osmosis membrane, cold method etc.The water shortage status of some areas has been alleviated in the application of these technology to a certain extent, but these methods not only will consume the conventional energy resourcess such as a large amount of electric power and fuel, further aggravated energy scarcity, and cause again new pollution, so the research of solar seawater desalination more and more causes people's concern.Desalination with Solar Energy has and does not consume conventional energy resources, pollution-free, gained fresh water purity advantages of higher and be subject to gradually people and pay attention to, and is a kind of desalination technology of Sustainable development.At present common desalination with Solar Energy utilizes sun power to produce heat energy direct heating sea water by distillation phase transition process take distillation method as main, namely produces evaporation and condensation.Existing existing system device is divided into active and passive type two classes, do not use the electric energy driving element in the device of passive type sea water desaltination, fairly simple, optional equipment has been used in the active solar energy distillation, is designed to the structures such as multistage distillation for improving the sun power utilising efficiency.Existing solar energy sea water distillation desalination techniques also has some shortcomings, and larger such as occupation area of equipment, the systematic procedure power loss is more, and the passive type solar energy distillation plant is simple in structure, but thermo-efficiency is lower, and the active solar energy distillation plant is complicated, and cost is high; In addition, also generally lack sun power and wind energy are carried out complementation, take full advantage of local renewable and clean energy resource, in one day, obtain the more fresh water of volume.
In recent years, because the development of hygroscopic material absorption agent has remarkable progress, absorptionmachine, absorbed moisture removing conditioning unit that application moisture absorption technical development is got up use in a lot of fields.Studies show that, the haloid element an alkali metal salt, as lithium chloride, lithiumbromide, calcium chloride etc. have nontoxic, odorless, harmless, without advantages such as high pressure explosion hazards, the absorbent solution that their consist of has strong sorption to aqueous vapor, for example, concentration is 40% water lithium chloride solution, temperature is in the time of 25 ℃, and saturation vapor pressure is 0.55kPa, and concentration is 50% lithium bromide water solution, temperature is in the time of 25 ℃, and saturation vapor pressure is 0.85kPa; The saturation vapor pressure of pure water in the time of 25 ℃ is 3.17kPa, is 5.62kPa in the time of 35 ℃, is 9.58kPa in the time of 45 ℃.Under uniform temp, the saturation vapor pressure on above-mentioned concentration absorbent solution surface is much smaller than the saturation vapor pressure on pure water surface, under the effect of pressure gradient power, a large amount of water moleculess breaks away from pure water and is absorbed the agent solution absorption, its strength of solution is declined to become dilute solution, dilute solution is heated, under not high temperature (60 ℃-80 ℃), water molecules is easy to desorb getter from solution, because these haloid element an alkali metal salt fusing points are very high, they can not be vaporized itself, and therefore, what condensation was obtained to desorb getter aqueous vapor is pure fresh water.The saltness average out to 3.5% of seawater, the saturation water air pressure of seawater surface is near the saturation water air pressure on pure water surface under the uniform temp.With the moisture content in the absorbent solution absorption seawater, the heat energy (take water as carrier) that transforms with sun power is again separated absorption to absorbent solution; Obtain pure fresh water to separating the aqueous vapor condensation liquefaction after absorbing, this process has just realized the desalination processing of seawater, and this new desalination technology has practical value.
Summary of the invention
The object of the invention is to overcome existing take the deficiency of distillation method as main desalination with Solar Energy, a kind of new cross absorption solar energy wind energy desalting device for sea water is provided, with sun power, the complementary comprehensive utilization technique of wind energy, hygroscopic material absorbent solution is to the absorption of moisture content/solution absorption technology, the microelectronics observation and control technology combines, construct a kind of volume little, efficiency of energy utilization is high, structure is simpler, cost is low, practical sea water desalinating plant, can be converted into very soon the typing commodity, meet the need of market, for this reason, the present invention adopts following technical proposals to achieve this end.
