实验研究了半连续结晶器中混合特性与化学特性对反应结晶过程的影响,实验发现,混合特性对产物粒度分布的影响是非单调的,存在转捩点(criticl point),在该点平均粒径或方差为极小。分析表明,转捩点的出现是微观混合与宏观混合共同作用达到平衡的结果。
The effects of mixing and chemical properties on the crystallization process of semicontinuous crystallizer were studied experimentally. It was found that the influence of mixing properties on the particle size distribution of the product was non-monotonous. There was a critical point at which the average particle size or variance For the smallest. The analysis shows that the appearance of transition point is the result of the combination of micro-mixing and macro-mixing.
