Characteristics of Guided Trapezoid Valve Tray and Its Industrial Applications

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
