摘　　要：氯化钠广泛应用于多个领域,为更好地了解氯化钠的结晶原理,优化其结晶过程,对氯化钠在搅拌反应器中的结晶动力学进行了实验模拟,以研究氯化钠晶体在30℃条件下搅拌结晶过程中晶体的成核过程和生长过程,以及搅拌速度、过饱和度和悬浮密度对氯化钠晶体结晶过程的影响,并通过测得的多组数据采取多元非线性拟合的方法构建氯化钠晶体的成核和生长动力学模型。Sodium chloride is widely used in various fields.In order to better understand the crystallization principle of sodium chloride and optimize its crystallization process,the crystallization kinetics of sodium chloride in a stirred reactor were experimentally simulated to study the nucleation and growth process of sodium chloride crystals during the stirring crystallization process at 30℃,as well as the effects of stirring speed,supersaturation,and suspension density on the crystallization process of sodium chloride crystals,And a nucleation and growth kinetics model of sodium chloride crystals was constructed using a multivariate nonlinear fitting method based on multiple sets of measured data.
