Abstract: Float valve tower is a widely used vapor-liquid mass transfer equipment. The new valve trays developed from F1 valve tray in China are introduced. These new value trays have lower pressure drop，lower entrainment rate，lower weeping rate，and higher processing capacity. The structure，hydrodynamics，mass transfer efficiency，advantages and disadvantages are summarized，focusing on time of development and type of tray. Valve tray design and development concepts of each series are summarized. The successful example of directed valve trays applications in Qilu Petrochemical butadiene unit is described. The quality of product and tray loading rate are greatly improved. Some common trays used in industrial production are introduced. The development ideas of these new valve trays are described. The float valve is mainly bar shape and a directed hole is opened in most valve trays. Future research and development of tray technology are prospected.

摘要： 浮阀塔是一种应用极为广泛的汽液传质设备，本文介绍了国内研究开发的新型浮阀塔板。这些浮阀塔板是在F1型浮阀塔板的基础上开发而成的，相比于F1型浮阀塔板，具有压降低、雾沫夹带量小、泄漏量小、处理量大等优点。本文以塔板的开发年代和塔板类型为主线，对这些浮阀塔板的结构特点、流体力学、传质性能、优缺点等进行了概括总结，对每个系列浮阀塔板的设计开发理念进行了总结概括，同时介绍了导向浮阀塔板在齐鲁石化公司丁二烯装置中应用的成功实例，很大程度地提高了塔板负荷率和产品质量；并简单介绍了一些常用塔板在工业生产中的应用情况，阐述了这些新型浮阀塔板的发展思路，即浮阀形状以条形为主，并且大部分浮阀塔板都开有导向孔；最后指出了今后塔板技术的研究和发展动向。
