This study examined the phenomenon of particle segregation in lean-phase binary mixtures, with a specific focus on the effect of particle size variations while flowing over a continuous liquid fluidized bed (LFB). The experimental configuration included a cylindrical column with a 72 mm internal diameter and 3 m vertical height. The binary mixture considered for this investigation was made up of solid materials that were rich in flotsam and jetsam. The study encompassed various factors, including liquid velocity, solid feed rate, and feed composition, in order to examine the separations containing flotsam and jetsam. A segregation index was calculated for each of the various combinations. On the other hand, the fluidization of the blend consisting of two solid components displayed notable differences in its behavior when compared to the reported effects of particle separation in any of the mixtures. Empirical correlations have been employed to establish relationships between variables, particularly with respect to solid entrainment and top and bottom product purity levels.

连续液体流化床中贫二元混合物偏析的实验分析

本研究研究了贫相二元混合物中的颗粒分离现象，特别关注流经连续液体流化床 (LFB) 时颗粒尺寸变化的影响。实验配置包括一个内径为 72 mm、垂直高度为 3 m 的圆柱形柱。本次研究考虑的二元混合物由富含废弃物和废弃物的固体材料组成。该研究涵盖了各种因素，包括液体速度、固体进料速率和进料成分，以便检查含有废料和废渣的分离物。计算每种不同组合的分离指数。另一方面，与报道的任何混合物中颗粒分离的效果相比，由两种固体组分组成的共混物的流化表现出显着的行为差异。经验相关性已被用来建立变量之间的关系，特别是在固体夹带以及顶部和底部产品纯度水平方面。
