Description
(1) technical field
The present invention relates to the technical field of pottery manufacturing and applications in ceramics, is about ceramic solar energy heat-collection body-ceramic solar plate specifically, says so in more detail about having the ceramic solar plate of air heat insulating layer.
(2) background technology
Solar energy is the basic source of conventional fossil energies such as coal, oil, natural gas and wind energy, water energy, ocean energy, biomass energy, the solar energy that is radiated earth top is tens thousand of times that global human consumes gross energy the same period, be 10,000 times of global wind energy total amount, water can 100,000 times.
The advantage of solar energy is general, huge, harmless, shortcoming is to disperse, at random, intermittently, the research of solar energy utilization mainly is the research to solar energy collecting, conversion and device thereof, because solar energy is the low-density energy, huge energy dissipation is in wide zone, so research to solar collector is the more important thing is in the research of solar energy utilization, be cost, life-span, Study on Efficiency to solar collector.
Solar collector mainly comprises metal plate type, glass vacuum tube type, light-focusing type gatherer and solar cell etc. at present, helioplant mainly comprises solar water heater, solar water heating system, solar heat wind system, solar cooker, solar energy housing, solar drying apparatus, solar energy greenhouse, solar refrigeration and air-conditioning system, solar heat power generation system, solar photovoltaic generation system etc.
The solar collector of industrialization at present, the marketization, scale utilization mainly is metal plate type, glass vacuum tube type gatherer and solar cell.
The purpose of utilizing solar energy is in order to save and alternative conventional energy resource, key is the gain and loss of energy, be the ratio of the conventional energy resource that solar energy and gatherer consumed that obtains of gatherer life period, we claim this value to be the A value, the energy that consumes owing to gatherer itself is difficult to calculate the ratio of using the obtained solar energy total amount of its life period of this solar energy equipment to be converted into mark coal price value and device price, with this A value that draws is not a value in strict conformity with definition, but the A value is an objective reality.The A value also can be regarded an economic indicator as.
Solar thermal collector is a stock with copper, aluminium, Pyrex, stainless steel, color steel at present, to make meticulous low thermo-paint is sunlight absorbing layer, with complicated technology operation manufacturing heat collection body, to keep condition of high vacuum degree is one of insulation measure, but the sunlight absorptance of these solar thermal collectors can decay, metal material can burn into vacuum descend in time, efficient decreases, with this high energy consumption, high cost, than short life, than the goods of harmonic(-)mean efficient in the face of very thin, low-density solar energy, can not obtain higher A value.Only change associated materials, manufacturing process and modular construction make the cost decline several times of existing solar thermal collector, life-span prolong several times, sunlight absorptance long-term stability, just may obtain higher A value.
Preresearch estimates thinks that the A value of glass vacuum tube type water heater is 2.16-0.864, and the A value of metal plate type water heater is 1.44-0.48, and the A value of solar cell is about 0.1.
About 600 yuan of present one ton of solid hair plates of common porcelain, 3000 yuan in cast iron, 4500 yuan of steel, 24000 yuan of aluminiums, 70000 yuan of copper materials, ceramic material is cheap to be because the raw material reserves are big, widely distributed, haul distance is short, about 1200 ℃ of firing temperature, firing time is short, processing technology is simple.It is because the raw material reserves are few, effective content is low, haul distance is far away, about 1600 ℃ or need electrolysis for production, processing technology complexity of smelting temperature that metal material costs an arm and a leg.The Pyrex 3.3 of making glass-vacuum tube are special glass, wherein silica 80%, boron oxide 12%, glass melting temperature is higher than 1600 ℃, the processing technology complexity, about 20000 yuan per ton of boron oxide price, every square metre of heavily about 14kg of daylighting surface glass vacuum tube, need the stainless steel manifold in addition, these factors are difficult to change.The about 10 yuan/m of present 800 * 800 * 12mm conventional ceramic hair plates production cost
2, vanadium-titanium black ceramic is decorated the hair plates production cost can be lower than 17 yuan/m
2Hollow ceramic solar panel total thickness 20～60mm, when continuously shaped, wall thickness 3-5mm, aspects such as the plant area of the energy consumption of burning till from raw material type, unit are raw material consumption, forming method and efficient, drying, device category, identical output, recruitment quantity are weighed relatively, can think that when both all adopt large-scale production both every square metre of production costs have comparativity.
The ceramic material that no whiteness requires is the minimum engineering material of known cost; one of construction material; it does not corrode; not aging; colour-fast; not oxidation; high strength; high rigidity; high rigidity; high-compactness; high temperature resistant; long-life characteristic is fit to make the solar energy heating body very much; its unique shortcoming-fragility is also owing to be in glass plate when using and cover down; can not embody in the insulation material encirclement; the solar thermal collector of manufacturing is compared with traditional solar thermal collector; cost may descend several times to ten times; life-span may prolong several times to ten times; keep the time of initial sunlight absorptance may prolong ten times to tens times; so the A value of ceramic solar board heat collector may be than big several times to tens times of the A value of traditional solar thermal collector; thereby may make solar energy have lower production cost than conventional energy resource; other consumed resources still less, better environmental protection effect.
The common recognition of scientific circles is at present: the solar radiant energy total amount that arrives earth top, than big several ten thousand times of the total amount that consumes the various energy same period on the earth, in case technical making a breakthrough makes it to have competitiveness on cost, solar energy can satisfy human most energy demand.
