Patent Information Analysis on Low Temperature Multi-effect Seawater Desalination Technology

采用专利公开数据对低温多效海水淡化技术的专利情况进行全面检索,在多效蒸馏海水淡化技术领域,专利分布较宽,基本涵盖了蒸发器、压缩机、换热器等关键设备的结构、海水淡化工艺系统、预处理系统、设备防腐剂、装置控制方法等各个海水淡化过程。日本、法国、以色列等国家研究起步较早,近年来该技术在我国快速发展,我国目前已成为该技术领域专利(申请)量最多的国家。

Low temperature multi-effect seawater desalination technology is researched entirely through public data. The technological development in this field is welled handled in view of fully understood. Patents distributes widely in multi-effect distillation for seawater desalination technology. Basically, it covers construction of evaporimeter, structure of compressor, formation of heat exchanger, and other key devices and construction. And it also covers each seawater desalination process, like seawater desalination system, pre-treatment system, equipment anticorrosion, auxiliaries and device control methods. Japan, France, Israel and other countries research early. In recently years, the technology develops rapidly at home, and China becomes a nation which has the largest number of patent application in this field at present.
