高温多效蒸馏及在核能海水淡化方面的应用

作为安全和清洁的能源，核能大规模应用于海水淡化可以从能源和水安全两个方面有效缓解我国当前面临的严峻形势。清华大学目前正在研究与低温核供热堆耦合的多效蒸发海水淡化技术。作为选择方案之一，高温多效蒸馏海水淡化所需蒸汽参数恰好与核供热堆提供的蒸汽参数一致。因而清华大学在高温多效蒸馏海水淡化研究领域开展了实验和理论研究工作。本文介绍了高温多效蒸馏海水淡化技术的特点，发展情况及目前清华大学开展的有关实验研究的进展。

TECHNOLOGY OF HIGH TEMPERATURE VTE-MED AND PROGRESS IN NUCLEAR DESALINATION RESEARCH IN CHINA

Nuclear energy greatly using in seawater desalination can be efficient in solving the shortage problem of energy and water in China. A vertical evaporation tube MED plant coupled with a natural circulation heating reactor was studied and designed by the Tsinghua University. The motive steam temperature of the high temperature VTE-MED technology is just the same as the that of the steam provided by the NHR. So the researches on experiments and theories in the field of VTE-MED have been carried out by the Tsinghua University. This article is focused on the development and the progress in experimental research on this VTE-MED process in Tsinghua University.
