机械蒸汽压缩蒸发技术研究现状与发展趋势

Recent progress and development trend of mechanical vapor compression evaporation technology

针对机械蒸汽压缩(MVC)蒸发系统的研究存在以下三个问题:(1)针对工作原理,没有提出更为深入的热力过程描述;(2)针对流程型式,没有建立更为全面的分类体系与方法;(3)针对应用案例,没有归纳更为系统性的设计和运行规律。基于此,重点介绍了MVC蒸发系统的原理与系统组成、分类与流程型式、应用与工程案例,综述了MVC技术的研究现状、存在问题与未来发展趋势。

At present,the research on mechanical vapor compression(MVC)evaporation system has the following three problems:(1)For the working principle,no more in-depth descriptions of the thermodynamic process is proposed;(2)For the process types,no more comprehensive classification methods is established;(3)For the application cases,more systematic design and operation rules are not summarized.Therefore,the principle and system composition,classification and process type,application and engineering cases of MVC evaporation system are introduced emphatically,the research status,existing problems and future development trend of MVC technology are reviewed deeply,comprehensively and systematically.
