Abstract
The utility model discloses a high reflectance solar reflecting mirror, including preceding support column, back support column and a plurality of speculum, a plurality of speculum end to end formation arc structure, the bottom of preceding support column and back support column respectively with the top both ends fixed connection of base, the top of preceding support column and back support column all with the bottom fixed connection of speculum, the speculum includes optical glass substrate and stereoplasm protective layer, medium coating materials, chromium reflection stratum, aluminium reflection stratum, metal protection layer and reflection layer of compensation has set gradually in the clearance between optical glass substrate and the stereoplasm protective layer. This high reflectance solar reflecting mirror, simple structure, reasonable in design can effectually carry out anti -oxidation protection to chromium reflection stratum and aluminium reflection stratum, avoids leading to the reflectivity of speculum to descend owing to use for a long time, can reflect the compensation to the chromium reflection stratum and the aluminium reflection stratum of speculum, has improved the reflectivity of speculum.
Description
Technical field
The utility model relates to application of solar, is specially a kind of high reflectance solar energy reflection mirror.
Background technology
The day by day exhausted and nuclear leakage event of the fossil energies such as coal, oil, rock gas has caused the once again thinking of the mankind to new forms of energy strategy, will solar energy fixedly be " the supplementary energy of recent urgent need " and " basis of future source of energy structure " finally.China is the country of main energy sources with coal as one, and energy scarcity, environmental pollution have become the bottleneck of the restriction sustainable development of socio-economy, just seem particularly important to the exploitation of new forms of energy.Solar energy thermal-power-generating (CSP) is based on focusing technology, different according to light acquisition mode, be divided into tower, slot type and dish-style, wherein slot type CSP technology is current unique business-like solar energy thermal-power-generating technology in the world, and the size of catoptron used is based on 1640 × 1700mm and 1510mm × 1700mm.Catoptron, as the core component of solar thermal collector, directly determines the collecting efficiency of whole system.
Solar energy reflection mirror still uses surface reflection minute surface both at home and abroad at present, namely there is at base material (shaping metal or nonmetal) surperficial evaporation or brushing one deck the material of high reflectance, or metal surface is processed process form, such as thin aluminum sheet surface anodization, corrosion resistant plate surface finish, or rhodanizing etc. after sheet iron copper coating, the easily frayed or dust effect and affect reflectivity of this surface reflection face; Another kind is backside reflection minute surface, be coated with last layer reflecting material at the back side of base material, advantage is that itself can clean, durable in use, currently available technology is that reflectance coating of aluminizing on a glass substrate makes glass mirror, then bonds with liner plate and make thermal-arrest eyeglass, and this specular reflectance is low, directly affects the collecting efficiency of whole collecting system, so we propose a kind of high reflectance solar energy reflection mirror.
