Description
Technical field
The present invention relates to flat-plate solar collector absorber plate preparation method, especially a kind of superconducting flat solar absorber plate spraying preparation method.
Background technology
In the carbon revolution of being moved towards low-carbon (LC) by high-carbon, the energy-conserving and environment-protective characteristic of solar thermal utilization receives much concern.According to statistics, solar energy high-end product---superconducting flat solar water heater system can realize building energy conservation 15% to 20%, and dwelling house adopts the superconducting flat solar energy heating system, can be building and saves energy consumption 50%.Aspect efficiency of energy utilization, the superconducting flat solar conversion efficiency can reach more than 78%, far away higher than vacuum tube.In building integration was used, superconducting flat solar energy more met unique and sees property, and has roofing and thermal-arrest dual-use function concurrently, for the energy-saving and emission-reduction of whole building play a significant role.Panel solar is the main product on the international market, and domestic market panel solar recent years also develops rapidly.
The absorber plate of superconducting flat solar water heater, it is the critical piece of panel solar system, it can be with the solar radiation energy transform into heat energy, then with superconductive heat transfer comb, the union pipe of thermal energy conduction to the superconductive solar heat collector, heating the flow through water of upper union pipe or the water in hot water storage tank.The absorber plate of flat-plate solar collector in the market generally is comprised of metal aluminum sheet, copper coin or steel substrate and surface optical coating two parts, i.e. selective and non-selective absorber coatings.Coating for selective absorption absorptance and non-selective coating all can reach 96%, but infrared external reflection is more much higher than coating for selective absorption than non-selective absorber coatings, and therefore the emphasis of research mostly is solar selectively absorbing coating at present.Coating for selective absorption is generally used electrochemical process, galvanoplastic, vacuum vapor deposition method or control sputtering method prepare, the absorber plate investment made from these technology and equipments is large, and energy consumption is high, Fei Gongshi, pollute more, material component is single, the cost extra-high-speed, and the absorber plate poor performance that Use Limitation fruit and spraying process are made on the superconducting flat solar thermal collector not what.do at water and heat transfer liquid the coating that the panel solar of medium uses spraying process to make, its absorptivity is 95%～96%, reflectivity is more than 18%, but the superconducting flat solar energy that uses superconductor technology to make is a different in nature superconduction heat absorption, conduct heat and heat-exchange system, the thermal conductivity factor of system is almost water or heat transfer medium thousands of times, heat absorption, heat transfer and rate of heat exchange are exceedingly fast, adopt the absorber plate of spraying process making in conjunction with superconducting heat collection, conduct heat and heat-exchange system, its absorptivity can reach 95%～98%, comprehensive infrared external reflection ratio reaches 12% left and right, its effect can reach the technical merit of international flat plate solar water heater fully.The at present domestic panel solar absorber plate that generally uses, i.e. " blue titanium plate " is mostly from German import, approximately 5,000 ten thousand square metres of year import volumes, spend a large amount of foreign exchanges, made the cost of panel solar high, affected applying of panel solar.
