Abstract
FST tray is one kind of spray tray.Comparing with bubble tray,it has higher flux and lower pressure drop.The tray structure influences mass transfer efficiency and pressure drop of the tray.In order to increase tray performance,different tray structures need to be investigated.A CFD model was developed by FLUENT to predict the gas phase flow field of FST tray.The gas phase flow fields of three different tray structures were compared and the effects of demist vanes and radial direction angle of rotating stream vanes were investigated.Results showed that demist vanes could decrease entrainment rate,but caused extra pressure drop.Rotating stream vanes with radial direction angle could increased swirling intensity, and enhanced mass transfer performance.However it would also increase pressure drop and backflow.Hence,in order to achieve optimal design,effects of structures should be considered comprehensively,and balance tray pressure drop,mass transfer performance and demist performance.关键词
