【摘要】：基于利用低品位熱源探求新的節(jié)能途徑以降低海水淡化成本的目的,借用熱管的高熱流密度傳熱特性設(shè)計(jì)并搭建了鹽溶液在真空條件下的霧化閃蒸水分離實(shí)驗(yàn)臺(tái),實(shí)驗(yàn)初步測試了影響水分離率的主要因素,分析了不同壁厚熱管軸向的溫度分布規(guī)律及傳熱性能。結(jié)果表明:噴霧特性、低品位熱源溫度等都是影響水分離率的重要因素;熱管能迅速將熱量傳遞給正處于閃蒸降溫過程中的鹽溶液液滴,即使在35~40℃的低品位熱源驅(qū)動(dòng)下,也可實(shí)現(xiàn)較高的水分離率;直徑10 mm長450mm的熱管導(dǎo)熱功率最高可達(dá)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，
