低温多效海水淡化蒸发器变工况参数的研究

Study on Variable Working Parameters of Low-temperature Multi-effect Desalination Evaporator

针对某电厂海水淡化工程的研究,建立了低温多效海水淡化蒸发器(带蒸汽热压缩器)的热力计算模型,并对蒸发器进行了理论计算和分析。利用蒸发器热力计算程序,对不同的工作条件下的低温多效蒸发器进行设计计算和校核计算,得到重要的设计参数,如造水比、动力蒸汽流量等。

In view of the research of a power plant desalination project,the thermal calcula⁃tion model of low-temperature multi-effect desalination evaporator(with vapor thermal compressor)was established,and theoretical calculation and analysis of the evaporator were carried out.By us⁃ing evaporator thermal calculation program,the design calculation and calibration calculation of low temperature multi-effect evaporator under different working conditions were carried out to obtain im⁃portant design parameters,such as GOR,power steam flow rate,etc.
