新型垂直筛板单罩液体提升量的测定与关联

Determining the Amount of the Lifted Liquid for New Vertical Sieve Tray with Cap Units

在有机玻璃冷模塔内，用空气－水物系测定了单罩液体提升量。根据实验结果，分析清液层高度、板孔气速与板孔大小对提升量的影响，并得出了相应的关联式，可供设计参考。

The amount of the lifted liquid of cap units was determined in a 600×160mm rectangular column with air-water system.The influences of the liquid height to tray,gas velocity and tray hole size upon the amount of lifted liquid were studied and the correlation was obtained. It will be of interest to sieve tray designer.
