开式热管低温海水淡化的余热回收技术

Open Heat Pipe for Desalination with Waste Heat

摘要: 为提高电厂能源效率需改善其冷凝热的利用，本文提出开式热管回收冷凝热的余热进行海水淡化的方法。实验研究中将环路热管变为开式热管实现水的低温相变，系统运行时的驱动力为多孔材料中汽液界面的毛细力。理论上随着海水浓缩程度的提高；蒸发与冷凝温度差的减小，此系统的热力学第二效率随之提高。

Abstract: To improve energy efficiency, condensing heat recovery is taken out with a novel method in this work. Open heat pipe is first put forward to heat the seawater and obtain the fresh water. A loop heat pipe is tested by opening way in experiment, and the result shows low temperature in the evaporation. Without input energy, the driving force of the system is mainly by the capillary force. The second law efficiency of this method is depended on the performance ratio and the phase change temperature a lot.
