摘　　要：通过改变气液相速率、清液层高度、泡罩立体筛板型式和内伸长度等对泡罩立体筛板(N-BTS)的液相提升量进行研究,得到最佳的操作和结构参数,以及液相提升量与孔板动能因子及清液层高度的数学关联式。并将N-BTS与垂直筛板和泡罩立体筛板(BTS)进行对比,结果表明,新型泡罩立体筛板的液相提升效果优于垂直筛板和BTS。The liquid elevated quantity of the new bubble-cap tridimensional sieve （N-BTS） is studied by varying the operation parameters such as the gas and liquid flow rates, the height of clear liquid, the types of bubble-cap tridimensional sieve and the length of stretch. The optimal operating parameters are obtained. Based on the experimental data, the correlative equation can be achieved for calculating the liquid elevated quantity. Compared N-BTS with BTS and VST,the results showed that the N-BTS is better than VST and BTS.
