【摘要】 介绍了导向浮阀塔板的结构特点、实验研究和工业应用情况。由于导向浮阀塔板上的液面梯度较小，液体返混较小，并可消除塔板上的液体滞止区，因而具有优秀的操作性能。导向浮阀塔板已在近百个塔内工业应用，均获得显著的经济效益。更多还原

【Abstract】 The structural features,experimental studies and industrial uses of directed valve trays are presented. It is showed that the hydraulic gradient and the liquid mixing on the tray are very small and the stagnant regions on the tray can be eliminated due to the structural characteristics of directed valve tray. Therefore,the directed valve tray has an excellent operating performance. The directed valve trays have been used about a hundred columns in industry and all of them have given a considerable economic result.更多还原
