Abstract
The invention provides a method for automatically cleaning a solar collector. The method comprises the steps of: opening a clear water valve of an atomizing spray head arranged on the solar collector, spraying clear water onto the surface of a reflecting mirror of the solar collector, and wetting the surface of the reflecting mirror; closing the clear water valve of the atomizing spray head; opening a cleaning liquid valve of the atomizing spray head, and evenly spraying the cleaning liquid onto the surface of the reflecting mirror; closing the cleaning liquid valve of the atomizing spray head; using a motor to drive a brush arranged on the solar collector to spin on the surface of the reflecting mirror; stopping the motor; opening the clear water valve of the atomizing spray head, spraying the clear water onto the surface of the reflecting mirror and washing the surface of the reflecting mirror; and closing the clear water valve of the atomizing spray head. The method can be used for automatically cleaning the solar collector with high efficiency and good better cleaning effect.
Description
Technical field
The present invention belongs to field of solar energy in broad sense, relates in particular to a kind of auto-cleaning method of solar collector.
Background technology
For a long time, people are just making great efforts research and utilization solar energy always.The solar energy that our earth receives only accounts for about 2 part per billion of whole energy of sending on sun surface, and these energy equivalences are inexhaustible in ten thousand times of the 3-4 of the required gross energy in the whole world.Secondly, the cosmic space not round the clock with the four seasons minute, do not have black clouds and shade yet, emittance is very stable.Thereby electricity generation system is simpler than ground comparatively speaking, and in the space environment of zero gravity, high vacuum, also not too high to the requirement of strength of element of installation.Moreover solar energy is different with fossil fuel such as oil, coals, can not cause " greenhouse effects " and global climate change, also can not cause environmental pollution.Just because of this, the utilization of solar energy is subject to the attention of many countries, and everybody is competitively developing various photoelectricity new technologies and photoelectricity new material, the application of utilizing to enlarge solar energy.Particularly during the nearly last ten years, day by day see the bottom and ecological environment goes from bad to worse under the pincer attack of these two large crises at the oil allowable exploitation, we are more and more looking forward to the arrival in " solar energy epoch ".From generating, heating, water supply to various solar power plants, its application is very extensive, and in some field, the utilization of solar energy begins to enter the practical stage.
In China, the utilization of solar energy also is the most popular topic always, through development for many years, domestic heat collector (containing solar water heater) become Application of Solar Energy the most extensively, industrialization one of industry the most rapidly.Gross sales amount had reached 3,500,000,000 yuan in 1998, and its output occupies world's umber one.The solar energy industry of China comes into operation.The Chinese Academy of Sciences announce to start western action plan, will conduct a research dropping into 2.5 hundred million yuans in two years, sets up the demonstration projects such as several solar electrical energy generations, solar-heating, solar airconditioning.The largest polysilicon solar cell production base of the present positive Accelerating The Construction of Baoding National High Technology Development District China, this Item Sets solar cell, assembly and application system etc. are integrated, after finishing, first stage of the project can reach the ability of producing 3 megawatt polysilicon solar cells per year, fill up China in the multinomial blank of solar energy development application facet, and will greatly promote the producing and selling market of the low iron glass of used for solar batteries.But analyze on the whole, domestic solar photovoltaic generation system is owing to start late, and especially also lags behind world level in the exploitation of solar cell, production, still is on the whole the primary stage that output is little, application surface is narrow, product is single, backward in technique.Show that through rough Statistics domesticly only have at present 5 (monocrystalline silicon) manufacture of solar cells factories, annual production has 4.5 megawatts (annotate: 1 megawatt (MW) is 1000 kilowatts) approximately, plant facilities still rests on the existing production line of introducing.And external many enterprises are in the exploitation and production of the more advanced film crystal solar cell of eye aiming.Its conversion efficiency of film crystal solar cell of the advanced person of this a new generation can up to 18.3%, improve 3 percentage points than at present average conversion efficiency.Introduce according to the insiders, the average conversion efficiency of China's solar cell is not high, its main cause is that the proprietary material degree domestic is low, such as the just complete dependence on import of packaged glass, the high permeability base plate glass market of low iron content still can not satisfy the demands, and scientific achievement does not also reach rapidly and is converted into industrial advantage fully.
In the actual application, when the speculum of collector array and solar panel are exposed to the external world for a long time, its surface unavoidably has dust, dust is overlying on heat collector and solar panel surface, can reduce the actual reflectance factor of speculum and the photo-thermal conversion efficiency that reduces photovoltaic, therefore, must keep as much as possible the speculum of collector array or the cleaning on solar panel surface.To arrange regularly manual cleanup of special cleanup crew in the prior art, great majority are the surfaces that cleaning agent are sprayed onto speculum or the solar panel of collector array with watering can, wipe clean with rag again, owing to a photovoltaic or the photo-thermal power generation station a lot of cell panels of needs or speculum eyeglass, therefore the required human resources that expend are huge; In addition, artificial effect of cleaning is non-constant also, is difficult to fully the mirror surface of collector array or the surface of solar panel be wiped clean.
Summary of the invention
The object of the present invention is to provide a kind of auto-cleaning method of solar collector, may further comprise the steps: the Clean water valve of opening the atomizer on the described solar collector, mirror surface to described solar collector is sprayed clear water, moistening described mirror surface; Close the Clean water valve of described atomizer; Open the cleaning fluid valves of described atomizer, described cleaning fluid evenly is sprayed on described mirror surface; Close the cleaning fluid valves of described atomizer; Hairbrush on the described solar collector rotates back and forth in described mirror surface under the drive of motor; Close described motor; Open the Clean water valve of described atomizer, described mirror surface is sprayed clear water, clean described mirror surface; Close the Clean water valve of described atomizer.
Optionally, described Clean water valve, described cleaning fluid valves, described motor are by chip controls opening and closing that are arranged in the described solar collector.
Owing to adopted technique scheme, compared with prior art, the present invention has the following advantages: the auto-cleaning method of solar collector of the present invention passes through atomizer, automatic setting cleans to solar collector, not only cleaning process is than manual cleaning science more, and efficient is higher, and, more cleaner than manual cleaning, more using water wisely.
