Description
Technical field
The present invention relates to Solar use, particularly adopt the solar energy mirror of point focusing to realize solar energy acquisition, adopt solar energy point focusing to realize the focus tracking sea water desalinating plant of sun power, the focusing relating to sun power utilizes.
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 desalinating plant in the whole world is 13,000,000 cubic metre/day.By 2000, this numeral 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, every day produces 13, the desalination water of 000,000 cubic metre, needs every year to consume crude oil I.3 hundred million tons.Even if people are affordable the expense of this fuel, but the Greenhouse effect of the earth, atmospheric pollution etc. also 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 be subject to people narrows.
Mankind's early utilization sun power carries out sea water desaltination, mainly utilizes sun power to distill, so early stage solar energy sea water desalination apparatus is generally all called solar still.Early stage solar still yields poorly due to water, and first current cost is high, in a very long time, be thus subject to the unfrequented of people.After the World War I, solar still causes the great interest of people again.Many new devices were developed out at that time, such as ceiling mounted, inclination curtain core type, inclined tray and inflatable solar still etc., for the domestic water of martime rescue at that time and the people solves very large problem.The operation logic of solar still utilizes sun power to produce heat-driven seawater to undergo phase transition process, namely produces evaporation and condensation.Operation scheme generally can be divided into direct method and the large class of indirect method two.As its name suggests, direct method system directly utilizes sun power to distill in heat collector, and the solar energy collector of indirect method system is separated with sea water by distillation part.But over nearly more than 20 years, the mixing system of existing many scholars to direct method and indirect method has carried out dark people's research, and according to whether using other solar energy collector again solar distilling system to be divided into the active and large class of passive type two.
The example of passive type solar energy Distallation systm is exactly disc type solar energy distillation device, and the application of people to it has had the history of nearly 150 years.Because its structure is simple, convenience of drawing materials, be still widely adopted so far.At present to the research of disc type solar energy distillation device mainly concentrate on the choosing of material, various thermal characteristics improvement and by it and all kinds of solar energy collector with the use of upper.At present, the efficiency of more satisfactory disc type solar energy distillation device is about 35%, and during fine sky, water production rate is generally at about 3 ~ 4kg/m.If add the black naphthylamines that concentration is 172.5ppm in the seawater, 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, is also unfavorable for working at night and utilizing other waste heat.For this reason, there has been proposed the design of tens of kinds of active solar energy distillers, and to this has been large quantity research.In active solar energy Distallation systm, owing to being equipped with other auxiliary facility, its operating temperature is greatly improved, or the heat and mass transfer process of its inside is improved.And, in most active solar energy Distallation systm, can the initiatively latent heat that discharges in condensing process of recovered steam, thus this type systematic can obtain the water production rate of one to several times higher than traditional solar still.
Focused solar energy seawater desalination system is the high-temperature hot collection adopting solar focusing tracking technique to realize sun power, then by sending heat energy to sea water desalting equipment, realizes sea water desaltination.
The generating of existing solar focusing heat is divided into slot type, tower, dish-style three kinds, and its solar energy acquisition part may be used for sea water desaltination.Usually tower, dish-style 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 utilizes technology mainly tower and butterfly two kinds, and dish-style system adopts solar energy mirror to focus in a solar utilizing equipment.And the solar utilizing equipment of existing dish-style technology is moved along with the change of sun glasses, because the weight of large solar utilizing equipment will increase load, be unfavorable for following the tracks of, thus existing dish-style technology needs to improve.
Tower system is as heliostat using a solar energy mirror, multiple solar energy reflection mirror is focused on the sea water desalinating plant on a sea water desalinating plant, due to the feature that tower type solar gathers, it is made to be only 4-6 hour in the time that utilizes of tracking solar procedure division solar energy mirror, solar energy mirror as tower east side cannot utilize substantially in the upper period of the day from 11 a.m. to 1 p.m, only have to noon or in the afternoon just can to utilize down, thus solar energy acquisition efficiency is low, this technical scheme can realize the collection of high temperature, but it is larger usually, be not suitable for small-sized or domestic system.
