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 trayguided 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 describedThe 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 trayThis guidance decreases and even eliminates the hydraulic head drop,reduces local weeping,improves the uniformity of vapor flowing,and increases tray efficiencyThe experimental results show that the guided trapezoid valve tray has an efficiency 5%~10% higher than F1 valve trayIn addition,industrial application of this new distillation tray in refinery plant is presented
