Mixing and Segregation of Particles in a Gas-Liquid-Solid Fluidized Bed in Batch Operation
三相流化床间歇操作中颗粒的混合与离析行为

Experiments were carried out to examine axial concentration distribution and mixing and segregation behaviour of binary solids mixtures in a three-phase fluidized bed of 41 mm I.D. and 1500 mm height under batch operation mode. Macroporous adsorption resin and rubber balls with different diameters but similar density were employed in the experiments. Multiple shutter plates and bed expansion method were used to determine axial variation of the bed properties including concentrations of particles in the bina...
