已经研究了喷动流化床中颗粒尺寸对混合和分离的影响（Zhang，Y.;钟，W.问：Jin，B. S.的;肖河，巴西-地喷动流化床中的混合和分离行为：颗粒尺寸的影响。2012，51，14247-14257）。本文研究了喷动流体中颗粒密度对混合和分离行为的影响。使用具有2.8mm的相同尺寸和900、1230、1640和2540 kg/m3的不同密度的四种固体颗粒。得到三种二元混合物，表示为PB-SP、PB-MB和PB-GB。对于每种混合物，制备三种不同的质量比，以便检查混合和离析过程。因此，通过将床料和示踪剂以不同的质量比混合而制成九种二元混合物。初始床层分别处于充分混合和完全离析状态。通过改变喷动与流化气流的比例，可以覆盖很宽的流型范围。混音...
The effect of the particle size on the mixing and segregation in a spout-fluid bed has been investigated (Zhang, Y.; Zhong, W. Q.; Jin, B. S.; Xiao, R. Mixing and segregation behavior in a spout-fluid bed: effect of particle size. Ind. Eng. Chem. Res.2012, 51, 14247–14257). This paper presents the effect of the particle density on the mixing and segregation behavior in a spout fluid. Four kinds of solid particles having the same size of 2.8 mm and different densities of 900, 1230, 1640, and 2540 kg/m3 were used. Three kinds of binary mixtures were obtained, indicated as PB–SP, PB–MB, and PB–GB. For each mixture, three different mass ratios were prepared so that the mixing and segregation processes were examined. Thus, nine binary mixtures were made by mixing the bed material and tracer in different mass ratios. The initial bed stayed in the state of well-mixed and complete segregation, respectively. A wide range of flow regimes were covered by changing the ratio of spouting-to-fluidizing gas flow. The mix...
