Description
【Technical field】
This utility model belongs to solar energy heat utilization field, and in particular to a kind of No clean reflecting mirror for heliostat.
【Background technology】
Tower type solar photo-thermal power generation is a kind of important solar energy generation technology, and its principle is using by a large amount of heliostats
The Jing Chang of composition by solar light focusing in central receiver with plus hot fluid, then fluid drives turbine is producing electric power.Jing Chang
The optical focus performance of middle heliostat directly affects the whole plant energy of whole tower power station.In order to ensure the optical of heliostat
Can, it is necessary to keep heliostat surface cleaning, accordingly, it would be desirable to periodically clean to heliostat, tripartite is primarily present among these
Face problem.
One is that water consumption is big.What at present the cleaning to heliostat was adopted is all water-washing method, to reach certain cleannes,
Cleaning frequency is generally weekly, and each water consumption is about 0.5 liter/square metre.Due to tower power station mirror field total reflection face
Accumulate generally tens of thousands of to hundreds of thousands square meter, therefore whole Jing Chang cleanings water consumption once is very huge.Further, since lack having
The sewage recovery method of effect, it is impossible to water is circulated and is used.
Two is that floor space is big.Because the cleaning requirement of heliostat is higher, needs can just complete thoroughly cleaning by cleaning Vehicle,
In order to give cleaning Vehicle reservation operations space, a certain distance is must assure that between front and rear row heliostat, this directly increases whole mirror
The floor space of field, reduces mirror field density.
Three is specular reflectivity rapid decrease.Because solar energy thermo-power station is usually located at drought area, dust storm compared with
Greatly, easily cause minute surface cut occur, reflectance is reduced, so as to affect the light gathering efficiency of heliostat.
These problems directly results in being significantly increased for power station initial cost and operating cost, have a strong impact on solar energy optical-thermal
The economic performance in power station.Therefore, the cleaning method for improving heliostat in solar energy thermo-power station is current problem demanding prompt solution.
【Utility model content】
This utility model aims to overcome that the deficiency of prior art, there is provided a kind of No clean reflection of heliostat
Mirror, saving water resource, and Jing Chang arrangements can be made compacter improves land utilization ratio, be greatly reduced the cleaning of heliostat into
This.
To reach above-mentioned purpose, this utility model patent is adopted the following technical scheme that and is achieved：
A kind of No clean reflecting mirror for heliostat, including protective paint layer, transition zone, reflecting layer, matrix and protecting film,
Wherein protective paint layer is located at lowermost end, from bottom to top respectively transition zone, reflecting layer, matrix and protecting film, the protective paint layer,
Transition zone, reflecting layer and matrix are one overall, form reflecting mirror；The protecting film is pasted on matrix surface and detachable.
Further, the mirror shape of heliostat is circular, rectangle or regular polygon.
Further, the protective paint layer at least includes one layer of uvioresistant protective paint.
Further, the transition zone is layers of copper.
Further, the reflecting layer is silver coating or aluminium coated.
Further, described matrix is the low iron glass of ultrawhite.
Further, the thickness of described matrix is 1-10mm.
Further, the material of the protecting film is polypropylene（PP）, polyethylene（PE）, polrvinyl chloride（PVC）, it is poly- to benzene two
Formic acid glycol ester（PET）In one kind or its combination in any.
Further, the material of the protecting film is comprising polypropylene（PP）, polyethylene（PE）, polrvinyl chloride（PVC）, it is poly- right
PET（PET）In the composite of any one.
Further, the thickness of the protecting film is 0.075-0.3mm.
The beneficial effects of the utility model are：
1. the No clean reflecting mirror for being used for heliostat described in is the specular surface stickup layer protecting film in traditional heliostat,
The protecting film is replaceable, when minute surface be contaminated cleannes it is not up to standard after, directly more renew protecting film.The method is changed
The water-washing method of traditional heliostat, has significantly saved the water consumption in power station.Especially solar energy thermo-power station is typically located at arid
Area short of rain, saving water resource is particularly important.
2. mirror protecting film exchonge step is simple, and without the need for equipment such as large-scale cleaning Vehicles, heliostat is respectively without the need for reserved clear between row
Space is washed, Jing Chang arrangements can be made compacter, improve land utilization ratio.
3. material used by protecting film is cheap, compared with water-washing method, the cleaning cost of heliostat can be greatly reduced.
4. scuffing of the dust storm to heliostat is irreversible, and over time, the light gathering efficiency of heliostat can be reduced persistently,
And increase after protecting film, dust storm acts only on protecting film, changes the condenser performance of heliostat after protecting film and can recover to initial value,
Effectively extend the service life of heliostat.
