海水淡化装置回热器技术研究

ON TECHNOLOGY OF REGENERATOR IN SEAWATER DESALINATION DEVICE

利用Aspen Plus软件分别对不同回热器设置方式下海水淡化装置的性能参数进行了模拟计算与对比分析,对回热器的设置位置、设置台数、抽汽位置等进行了系统分析,提出了回热器的设置方法。研究表明:增设回热器可显著提高装置产水率;回热器设置在总管时装置淡水产率高于设置在支管和小总管;回热器设置台数增多可提高产水率。研究成果对于实际工程应用具有指导意义。

The performance parameters of seawater desalination device under different regenerator setting modes were simulated and compared by using Aspen Plus software in this paper.The setting positions,setting number and air extraction positions of regenerators were analyzed systematically,thus the setting method of regenerator was proposed.The results show that the water production rate can be significantly improved by adding regenerators;the fresh water production rate of the unit is higher when the regenerator is installed in the main pipe than in the branch pipe and small main pipe.Increasing the number of regenerators in the seawater desalination device can improve the water production rate.The research results are of guidance for practical engineering applications.
