摘要
综述了气固流化床有关颗粒分离的研究概况及最新进展。既包括实验研究,又给出模型比较。讨论了不同研究结果之间的差异及存在的不足。指出了在这一领域中应该进一步进行深入研究的课题。
As one of the important projects of describing fluidization bdhavior of multi-component mixtures in gas-solids fluidized beds,the fundmental research on the particle segregation mech-anism and operation,the particle mixing principles and determination ,and the mathematicalmodelling for both segregation and mixing have been reviewed in this paper. In order to getmuch better quantitative creteria and more scientific explanation for this special project,it isclear that the following topics:the bubble flow characteristics,the micro-mechanism of segre-gation and mixing,the effects of high pressure and temperature,and the cntinuous operationin an actual gas-solid fluidized bed should be taken for detailed and further investigation.
