摘要
通过MSMPR结晶器系统对纯氯化钾及加入光卤石母液后的溶液,采用不同的搅拌速度及不同的桨叶材料进行了氯化钾结晶动力学的研究,计算出了不同的搅拌速度及不同的桨叶材料下氯化钾结晶的基本动力学关系式,分析了氯化钾结晶过程中成核与生长速率的影响程度,为用光卤石生产氯化钾产品,提高其取得率及增大晶体粒度提供了理论依据。
To adopt the different mixing speed and paddle material of MSMPR crystallizer system in the solution,including the pure KC1 and carnallitite mother liquor, we have conducted the KC1 crystallization kinetics research and caculated the basic kinetic equations of KC1 crystallization. In addition, we also analysed the degree of the effect of nucleation and growth speed in the process of KC1 crystallization. The results provide that the theoretical base for producing KC1 with carnallitite, enhancing the rate of getting KC1 and increasing the crystal grain size.
