摘 要: 文章采用聚焦光束反射测量仪(FBRM)研究了硫酸镍间歇结晶过程晶体的成核和生长规律,考察了搅拌桨形式、降温方式、搅拌速率、晶种添加量和晶种粒度对结晶过程中结晶动力学的影响。结晶工艺条件优化后,得到了粒径大、晶型好、分布均匀的晶体产品,为硫酸镍间歇结晶过程的工艺优化和工业放大提供了依据。 Focused Beam Reflectance Measurement(FBRM) was used to investigate the nucleation and crystal growth kinetics in the batch crystallization of nickel sulfate,and the effect of stirring paddle styles,cooling modes,agitating rate,seed loading and size on the crystal nucleation and growth was studied.After optimization of the conditions of crystallization process,the crystal product with big crystal size,nice crystal shape and narrow size distribution can be obtained.And it is promising for quality control of industrial production.
