介绍了影响流化床分选效果的因素,根据5种加重质的起始流化速度,确定适合分选的流化气速,利用示重块进行分选实验,在床内不同气速下分选90 s,分析对比其分配曲线,得出加重质E在气速3.88 cm/s时的E_p=0.08,此时床层密度接近分选密度,均匀性和稳定性较好,分选效果较好。 According to the starting fluidization velocity of five kinds of heavier substances, the fluidized gas velocity suitable for sorting is determined, the sorting experiment is carried out by using the weighting block, and the influence of different gas velocities in the bed Sorting 90s, analysis and comparison of its distribution curve, we can see that E_p = 0.08 when the mass E is at 3.88 cm / s, the bed density is close to the sorting density, the uniformity and stability are good, and the sorting effect better.
