适于核能海水淡化的低温多效蒸馏技术研究

Research of Low Temperature MED Technology With Nuclear Reactor as Energy Source

针对核能海水淡化技术，探讨了核能与海水淡化厂耦合的不同方式。水平式低温多效蒸馏由于其传热性能好、能耗低，传热温差较小，以及容易维修等优点，是非常适合与低温核供热堆耦合的海水淡化技术。在分析低温多效蒸馏海水淡化技术的基础上，建立了水平式低温多效蒸馏海水淡化物理模型，编写VB程序，并分析比较等温差分配和等传热面积分配两种方案的产水特性，结果表明等传热面积分配方案性能较好。

The technology of nuclear energy seawater desalination was discussed in the paper. The different interfaces of nuclear power applied in desalination technology were also analyzed. Because of good performance, low energy wastage and other reasons, the horizontal tube and low temperature MED （LT-MED） technology is very coupling with nuclear heating reactor （NHR）. Then, the principle and application of LT-MED technology were introduced. In the end, a physical-mathematical LT-MED model was developed to explore the thermal hydraulic performance. Two temperature difference distribution schemes, equal temperature difference and equal heat transfer area temperature difference, were analyzed for the system design.
