摘要

采用稳态法研究了气速、液速、固体粒子直径及密度和床径对三相流化床液相返混的影响.根据实验数据

获得了如下的计算Pe_l的关联式:Pe_l=24.32(U_l/U_t)~(1.2)U_g~(-0.34)D_t~(-0.5)d_pρ_s~2

Abstract

The effects of liquid and gas velocities

average diameter and density of solid particles and column diameter on liquid mixing in three-phase fluidized bed were determined. On the basis of the data obtained

the following correlation for Pe; was obtained:
