摘要

在φ300mm的实验塔中

用水-空气系统对“T”形排列条形浮阀塔盘及“VST”塔盘的流体力学性能及氧解吸效率做了实验研究。得出了塔板压降、泄漏、夹带、液层阻力降以及降液管中清液层高度的初步关联式。在相同实验条件下与F_1型浮阀塔盘的数据对比、分析的基础上

发现了VST和T形排列条形浮阀塔盘的分离效率和板压降与F_1型浮阀塔盘相当

而操作范围要比F_1型浮阀宽。

Abstract

An experimental study of the hydraulic performance and oxygen desorp-tion efficiency of a vertical sieve tray and T-arrangement rectangular valve tray has been made with water-air system in a 300mm test tower and preliminary correlations were obtained between the tray pressure drop

leakage

entrainment

pressure drop of the gas passing through the liquid layer

and the clear liquid height in the downcomer. On the basis of analysing and comparing the data of the two types of trays with those of F1-type circular valve tray

it is found

under the same experimental conditions

that the fractionation efficiency and tray pressure drop of VST and RVT are approximately equal to those of F1-type circular valve tray but the operating range is much wider than that of the latter type.
