摘要

本文以空气—水—煤油为介质

在600×l50矩形冷模塔内进行了气—液—液三相蒸馏导向筛板的流体力学特性的研究.实验就三相蒸馏塔板上的操作工况(Operating Regimes)及塔板上两液相混合状况进行了研究.并就清液高度、雾沫夹带、板压降等主要流体力学参数进行了大量测试

提出适用于混合工况的主要流体力学参数计算关联式.

Abstract

Three-phase distillation hydrodynamic behaviour was investigated with water and kerosene as the two immiscible liquids and air as the third phase. Experimental studies were carried out on flow-guide sieve trays in a 600 mm x 150mm rectangular perspex simulator. Spray

froth and mixed regimes

and transition regimes were studied. Liquid-liquid mixing was also studied in the experiment. Mathematical correlations for clear liquid height

entrainment rates

pressure drop and other hy-drodynamic parameters are given.
