Description
Technical field
The utility model relates to the sun power utilization, particularly adopts the solar energy mirror of point focusing to realize solar energy acquisition, adopts the focus tracking seawater desalination system of the transmodulator realization sun power of point focusing, relates to the focusing utilization of sun power.
Background technology
Solar seawater desalination utilizes sun power to realize the equipment of sea water desaltination exactly.
By nineteen ninety, the water-yielding capacity of the mounted sea water distiling plant in the whole world is 13,000,000 cubic metre/day.By 2000, this numeral was turned over one times.Increasing sharply of desalination water will produce a series of problem, and wherein the most outstanding is exactly the consumption problem of the energy.According to estimates, produce 13,000,000 cubic metre desalination water every day, need to consume I.3 hundred million tons of crude oil every year.Even people are affordable the expense of this fuel, but Greenhouse effect of the earth, atmospheric pollution etc. also the bulletin people must act with caution.Therefore, seek to carry out sea water desaltination with sun power, the green grass or young crops that will receive people narrows.
The mankind utilize sun power to carry out sea water desaltination in early days, mainly are to utilize sun power to distill, so early stage solar energy sea water desalination apparatus generally all is called solar still.Early stage solar still yields poorly owing to water, and first current cost is high, thereby in a very long time, receives the unfrequented of people.After the World War I, solar still has caused the great interest of people once more.Many at that time new devices were developed out, such as ceiling mounted, tilt a curtain core formula, inclination disc type and inflatable solar still or the like, at that time martime rescue and the people's domestic water have solved very big problem.The operation logic of solar still is to utilize sun power to produce heat energy driving seawater to undergo phase transition process, promptly produces evaporation and condensation.Operation scheme generally can be divided into direct method and indirect method two big classes.As its name suggests, the direct method system directly utilizes sun power in heat collector, to distill, and the solar energy collector of indirect method system and sea water by distillation partly are isolating.But over nearly more than 20 years, existing many scholars have carried out dark people's research to the mixing system of direct method and indirect method, and according to whether using other solar energy collector to be divided into the solar distilling system active again and passive type two big classes.
The example of passive type solar energy Distallation systm is exactly the disc type solar energy distillation device, and people have had nearly 150 years history to its application.Because its simple in structure, convenience of drawing materials is so far still by extensive employing.At present the research of disc type solar energy distillation device is mainly concentrated on the improvement of the choosing of material, various thermal propertys and it and all kinds of solar energy collector are used.At present, the efficient of more satisfactory disc type solar energy distillation device is about 35%, and in the time of fine day, water production rate is generally about 3～4kg/m.If in seawater, adding concentration is the black naphthylamines of 172.5ppm, output of distill water can improve about 30%.A critical defect of passive type solar energy Distallation systm is that working temperature is low, and water production rate is not high, also is unfavorable for working at night and utilizing other waste heat.For this reason, people have proposed the plan of tens of kinds of active solar energy distillers, and this has been carried out big quantity research.In the active solar energy Distallation systm,, its operating temperature is greatly improved, or its inner heat and mass transfer process is improved owing to be equipped with other auxiliary facility.And, in most active solar energy Distallation systm, the latent heat that in condensing process, discharges of recovered steam initiatively, thereby this type systematic can access than traditional solar still high one water production rate to several times.
The focused solar energy seawater desalination system is to adopt the solar focusing tracking technique to realize the elevated temperature heat collection of sun power, through sending heat energy to desalting plant, realizes sea water desaltination again.
The generating of existing solar focusing heat is divided into three kinds of slot type, tower, dish formulas, and its solar energy acquisition part can be used for sea water desaltination.Usually tower, dish formula can reach the collecting temperature of 800-2000 degree, utilizes this heat energy can realize the sea water desaltination of sun power.
Solar energy point focusing utilization technology mainly is two kinds of tower and butterflies, and dish formula system adopts solar energy mirror to focus on the sea water distiling plant.
Tower system is as heliostat with a solar energy mirror; A plurality of solar energy reflection mirrors are focused on a solar seawater desalination system on the sea water distiling plant, because the characteristic that tower type solar is gathered makes be merely 4-6 hour its time of utilizing in tracking solar procedure division solar energy mirror; Solar energy mirror like the tower east side can't be utilized in the last period of the day from 11 a.m. to 1 p.m basically; Have only to noon or just can utilize in the afternoon down, thereby solar energy acquisition efficient is low, this technical scheme can realize the pyritous collection; But it is larger usually, is not suitable for small-sized or domestic system.
