Technology and Application of Off-grid Wind Powered Seawater Desalination

报告了离网式风能海水淡化技术的现状,重点介绍风能发电+反渗透,风能发电+机械压缩蒸馏两种海水淡化工艺的技术原理和典型工程应用,并从提高风能发电稳定性和优化海水淡化工艺设计两方面提出了适应风能波动性的建议,为一些风力资源丰富而淡水资源匮乏的偏远海岛等地区供水提供了技术可行的途径。

The combination of wind energy and seawater desalination has become much more attractive due to its energy security and environmental friendliness, especially in the shortage of traditional energy reserves, while the views of environmental protection and sustainable development are growing in popularity today. The current situation of off-grid wind powered seawater desalination was reported in this paper, and the technical principle and typical engineering applications of two desalination processes, including wind power generation ＋ reverse osmosis desalination and wind power generation ＋ mechanical compression distillation desalination were introduced. And suggestions were put forward from the aspects of improving the stability of wind power generation and optimizing the desalination process design to adapt the wind energy fluctuation. It provided a technically feasible way to produce fresh water for some remote islands or other areas which were rich in wind resources but lack of fresh water.
