径向流吸附器流体流动特性及其结构参数优化
Flow characteristics of radial flow adsorber and its structure parameters optimization
摘要
Abstract
Non-uniform flow distribution along the axial direction usually exists in a Z-flow type radial flow adsorber which will decrease the utilization of adsorbents and even result in operating safety problems in cryogenic air separation. The structure parameters in a differential equation which determined the flow characteristics of Z-flow type radial flow adsorber were dimensionlessly processed, and the effects of structure parameters on flow distribution in the adsorber were investigated. The theoretical result of the flow distribution in an experimental radial flow adsorber was in agreement with the experimental data. Reducing the axial height of adsorption bed and the diameter of adsorbent particle could significantly improve flow distribution in the Z-flow type radial flow adsorber. However, the amount of processed air had little impact on flow distribution when kinematic viscosity of air and other structure parameters remained unchanged.关键词
