新型立体垂直塔板的开发现状

Development of new vertical sieve tray

新型立体垂直筛板是近年来应用较为广泛的一种筛板,其主要特点是气液并流接触,传质在塔板空间内进行.本文对近年来开发的几种新型立体垂直筛板进行了详细的介绍,对其流体力学性能进行了比较。

New VST is a kind of sieve plates that is widely applied in recent years. Its main character is that gas and liquid contact collaterally, and mass transfer is carried through in the plate place. This article introduces some kinds of new vertical sieve trays that are developed in recent years ,their hydrodynamics is compared ,and their foreground is predicted. 
