| 摘 要： | 在Ф１．２ｍ的冷模塔中对Ｖ型栅板的流体力学性能进行了实验测定，得出计算流体力学参数的关联式，并与大孔筛板和Ｆ１型浮阀塔板进行了比较，证明Ｖ型栅板是一种性能优良的塔板，为Ｖ型栅板的工程设计提供了参考依据，通过对塔板上气，液两相间的动量传递进行分析，讨论了动量传递对液面落差和清液层高度的影响。

| Abstract: | he hydrodynamic performance of a V-grid tray is determined in a test column 1.2m in diameter. A set of equations is obtained to correlate the hydrodynamic parameters.A comparison of the hydrodynamic performance is made between the V-grid tray and a large-holed sieve tray, also an F1 valve tray. It shows that the V-grid tray is good in performance. In addition, the momentum transfer on the V-grid tray and its effect on clear liquid height and hydraulic gradient cross tray are discussed. |
