【摘要】：基于利用低品位热源探求新的节能途径以降低海水淡化成本的目的,借用热管的高热流密度传热特性设计并搭建了盐溶液在真空条件下的雾化闪蒸水分离实验台,实验初步测试了影响水分离率的主要因素,分析了不同壁厚热管轴向的温度分布规律及传热性能。结果表明:喷雾特性、低品位热源温度等都是影响水分离率的重要因素;热管能迅速将热量传递给正处于闪蒸降温过程中的盐溶液液滴,即使在35~40℃的低品位热源驱动下,也可实现较高的水分离率;直径10 mm长450mm的热管导热功率最高可达150 W。
[Abstract]:Based on the purpose of using low grade heat source to find new ways to save energy in order to reduce the cost of seawater desalination, the experimental platform of atomization flash water separation of salt solution under vacuum condition was designed and built with the heat transfer characteristics of high heat flux of heat pipe. The main factors affecting water separation rate were preliminarily tested and the temperature distribution and heat transfer performance of heat pipe with different wall thickness were analyzed. The results show that the spray characteristics and the temperature of low grade heat source are the important factors affecting the separation rate of water, and the heat pipe can transfer the heat quickly to the droplets of salt solution in the process of flash cooling, even under the drive of the low grade heat source at 35 ~ 40 鈩，
