摘要
研发了一种与建筑一体化的新型高效平板太阳能集热体黑瓷复合陶瓷太阳板。该集热体以普通瓷土为原料配制泥浆注浆成型,表面喷涂以工业废弃物提钒尾渣为原料调配的钒钛黑瓷泥浆层,干燥后经连续辊道窑1 200℃烧制而成,阳光吸收比为0.95。介绍了陶瓷太阳板房顶集热系统的构建方法,该系统与建筑共用结构层、保温层、防水层,与建筑一体化、同寿命,隔热、保温效果优于普通房顶。通过建筑实例对该集热系统的集热效率与真空玻璃管热水器进行测试对比,得出集热系统日得热量为8.6 MJ/m2,远高于真空玻璃管热水器和国家标准的7.0 MJ/m2,可实现太阳能使用成本低于常规能源。
We develop a new and highly efficient flat solar body-the black porcelain composite ceramic solar plate. The solar body is constructed through slip casting with ordinary china clay as raw material, whose surface is sprayed with industrial solid wastes mixed black porcelain mud. The body is formed through firing at 1 200℃ by continuous roller kiln after drying, whose sunlight absorption rate is 0.95. We further present the construction method of ceramic solar plate roof solar heating system. The system shares structure layer, thermal insulation layer, waterproof layer with a building, is integrated with a building and has the same lifetime as a building. Its heat insulation and preservation effect is better than that of ordinary roof. Daily acquired heat of the solar heating system is 8.6 MJ/m^2, much higher than the national standard 7.0 MJ/m^2, by the comparison of heat collection efficiency of the system and that of vacuum glass tube water heater. The cost of solar energy is lower than that of conventional energy.
