摘  要:报道了新开发的导向梯形浮阀塔板的结构特点和性能,分析了这种新型浮阀塔板上气液两相的流动状况,揭示了其特有的利用气体的动量推动液体向前流动的导向推液作用,从而减小直至消除液面落差,减小局部漏液,改善气体流动的均匀性,进而提高塔板效率。试验测定结果表明,导向梯形浮阀塔板效率比F1型浮阀塔板提高了5%~10%以上。此外介绍了导向梯形浮阀塔板的工业应用。 newly developed distillation trayguided trapezoid valve tray is presented with its structure and performance,and the flowing and contacting situation of liquid and vapor phase on this new tray is describedThe guidance of vapor for liquid flowing forward is brought to light through analysis of the momentum transfer between the liquid and vapor phase on this trayThis guidance decreases and even eliminates the hydraulic head drop,reduces local weeping,improves the uniformity of vapor flowing,and increases tray efficiencyThe experimental results show that the guided trapezoid valve tray has an efficiency 5%~10% higher than F1 valve trayIn addition,industrial application of this new distillation tray in refinery plant is presented
