Abstract

利用太阳能淡化海水，在于设计一个太阳能接受装置，把太阳能转化为热能，用于海水的蒸馏以提取淡水，经发黑处理的钢板和导热油管平放于底部和四周都隔热的盘子内，盘子上面盖以中空的双层玻璃，盘内油管首尾相通，每一盘子有一进一出两个油管引进接口，多个盘子可串联使用。

Description

利用太阳能淡化海水
技术领域
本发明涉及到利用化学工业中常用的蒸馏技术，利用太阳能的光热转换，从海水中提取淡水。
背景技术
这是大自然中水的循环，从地球表面蒸发到天空，又以雨、雪的形式落到地面，而地面的蒸发大部分是海水的蒸发。另一方面，许多场合缺少淡水，却有丰富的海水资源，于是人们设想人为地从海水中提取淡水。蒸馏是人们考虑最多也是技术上最成熟的方法。只是由于能耗过大，成本太高而至今不能成为现实。
发明内容
本发明考虑利用太阳能来蒸馏海水以提取淡水。黑色物体可以把吸收到的太阳光能几乎完全地转化成热能，且其温度可以升高到足以蒸馏海水。在此考虑设计这样的太阳能接受装置，吸收太阳能并以热的形式保存下来，与大气相对隔热，最后以导热油为媒体，把热量输送到蒸馏设备。这样就能以相当低的运行成本，达到淡化海水的目的。
具体实施方式
根据本发明提供的技术方案，制一盘子，底部及四周由石棉或其他物质隔热，内置经发黑处理的钢板和导热油管。油管首尾相通、均匀地平放于钢板上，最上面盖以中空的双层玻璃，每一盘子由一进一出两个导热油管引出接口，多一个盘子可串联使用。阳光透过双层玻璃转化为热能，热能却不会散发到大气中。

Claims (2)

1.利用太阳能淡化海水在于设计一个太阳能接收装置，其特征是：经发黑处理的钢板和导热油管放在一个盘子内
2.根据权利要求1所述的太阳能接收装置，其特征是：盘子底部和四周由石棉或其他物质与外界隔热，盘子上面盖以中空的双层玻璃。
