摘要
采用连续稳态MSMPR反应结晶器,结合聚结-破裂生死函数粒数衡算模型对六氨氯化镁的结晶动力学进行了研究。通过改变传统破裂生死函数的表达形式,摆脱了等体积破裂假设限制,从而提出了改进后的二元随机聚结-破裂生死函数模型。在采用该模型对产品的粒度分布(PSD)数据进行离散变化求解后,获得了六氨氯化镁的结晶动力学参数。
The crystallization kinetics of hexammoniate magnesium chloride （MgCl2 · 6NH3） was investigated in a MSMPR crystallizer. The birth and death functions of agglomeration and breakage were used in the population balance model of the process. By changing the expression of current breakage birth and death function, we proposed an improved binary random birth and death function model of agglomeration and breakage, without the traditional equal-volume-breakage assumption. The parameters of crystallization kinetics of MgCl2 · 6NH3 were obtained by solving the model equations and fitting the particle size distribution （PSD） data.
