【摘要】：提出了微聚光直接蒸发海水实现淡化过程的概念,并在漂浮式透明膜板内的微结构中实施,即利用薄膜内部空腔,实现高效太阳能聚光,让太阳光直接加热并蒸发由亲水材料送入腔内的海水,实现海水淡化过程。它的最大优势就是将太阳能集热器与海水淡化器合二为一,漂浮于海面上,省却了土地成本,并可用非金属材料制造。本文对淡化膜中聚光产水单元的结构进行了优化设计,对其聚光过程进行了仿真分析,给出了太阳光不同入射角度下的聚光效率。并在样品结构中进行了稳态的实验验证,证明该装置最高温度可以达到70℃,产水量可以达到1.67 g/h,实现太阳能转化效率37.4%。
[Abstract]:The concept of seawater desalination by direct evaporation of micro-condensing light is proposed and implemented in the micro-structure of floating transparent film plate, that is, using the inner cavity of thin film to realize high-efficiency solar energy concentration. The seawater desalination process can be realized by directly heating and evaporating the water from the hydrophilic material into the cavity. Its biggest advantage is to combine the solar collector and the desalination device, float on the sea surface, save the land cost, and can be made of non-metallic materials. In this paper, the structure of the condensing water generating unit in the desalination film is optimized, the process of the condensing is simulated and analyzed, and the efficiency of the concentrated light under different incidence angles of the solar light is given. The experimental results show that the maximum temperature of the device can reach 70 鈩，
