摘要

在内径Φ30 0mm的填料塔中研究了孔板波纹填料的结构参数对液相轴向混合特性、流体力学和传质性能的影响 .研究结果表明

轴向返混参数随开孔率、倾角的增加及盘高的减小而增加

填料层压降随开孔率、盘高的增加及倾角的减小而降低

传质单元高度随倾角的增加、盘高的减小而降低

开孔率对传质单元高度的影响有一个适宜值 .通过对实验数据的回归分析得出了轴向返混参数、填料层压降及传质单元高度的关联式 .该研究结果对孔板波纹填料的开发与设计具有参考价值

Abstract

The influence of structural parameters of corrugated plate packing on its performance of axial mixing in liquid phase and hydrodynamic and mass transfer was investigated in a Φ 300mm ID packing tower.The results shown that the axial backmixing parameter Pe increases with increasing opening ratio and the inclination angle β and with decreasing the unit height of the packing H and that the pressure drop of packing layer Δ p/Z decreased with increasing opening ratio and unit height of the packing H and with decreasing inclination angle β and that the height of mass transfer unit H OG decreased with increasing inclination angle β and with decreasing unit height of the packing H

and that influence of opening ratio on the height of mass transfer unit H OG had a suitable value.Through regressing experimental data

the correlative expressions of the axial backmixing parameter Pe and the pressure drop of packing layer Δ p/Z and the height of mass transfer unit H OG were obtained.The results could be of value to development and design of corrugated plate packing.
