引入大颗粒助剂对径向移动床流动特性的影响
Effect of introducing large additive particles on flow characteristics in radial flow moving bed
摘要
Abstract
It does exist that some of abnormal phenomena, such as cavities and particle flow variations from plug flow, are inevitable in cross-flow moving bed operations. In terms of the issues related to the abnormal operation phenomena, the experiment was conducted through a large cold model experimental facility consisting of aφ600 mm×1300 mm semi-conical and semi-cylindrical radial flow moving bed. It showed that, the critical velocity of forming cavity can be effectively increased through introducing coarse additive particles, hence the low elasticity of operation can be improved in cross-flow moving bed to some extent. Both theoretical analysis and experimental results showed that, the inhomogeneity of particle flow can be effectively improved by introducing coarse additive particles.关键词
