摘要
针对叔戊醇钾生产过程中液固两相混合效果的强化,设计了新型搅拌装置,通过正交试验法,研究了搅拌桨桨型、挡板安装角度、釜内温度、搅拌转速和搅拌时间等影响因素对该体系固相分散的影响,通过自行开发的新型多相流图像识别系统,检测实验过程中液固两相流混合效果.结果表明,采用SG-6(2)搅拌桨、安装角度θ=90°的挡板、操作温度160~165℃、搅拌速度150~155 r/min、搅拌时间30 min为最佳优化条件,其局部固相体积分数达到11.98%.
In view of the enhancement of solid-liquid two-phase mixing effect in Potassium tert-butoxide production process,a new type of stirring device is designed in the paper.The influence of impeller baffle installation angle,temperature in the kettle,stirring speed and stirring time on the solid-phase dispersion of the system are studied by orthogonal experiment,and a novel multiphase flow image recognition system is developed to detect the mixing effect of solid-liquid two-phase flow.The results shows:the SG-6(2)impeller,the baffle with the installation angle ofθ=90°,operating temperature 160~165℃,stirring speed 150~155 r/min and mixing time 30 min are the best experimental conditions,with the partial solid phase volume fraction of 11.98%.
