新型垂直筛板塔预测板效率的数学模型

Mathematical Model for Predicting Tray Efficiency of New VST

笔者在新型垂直筛板塔表观板效率￣［２、３］的基础上，提出了汽相Ｍｕｒｐｈｒｅｅ板效率Ｅ＿（ＭＶ）及的计算式。并用曲线图表示出ｅ＿０、λ＿＿０、Ｅ＿（ＯＧ）、β＿０及Ｎ等参数对Ｅ＿（ＭＶ）的影响，以及ｅ＿０与Ｅ＿（ＯＧ）对的影响。

On the basis of the previous paper about the mathematical model forpredicting the apparent tray efficiency.E_(MV), in the presence of entrainment, an-other model is presented in this paper to calculate the vapor-phase Murphree trayefficiency E_(MV). The effect of e_0,λ_0, E_(OG),β_0,and N on E_(MV),as well as the eff-ect of e_0and E_(OG) on are disscussed and described in figures.
