摘要

对聚碳酸酯混合液

通过液液间歇沉降实验得到分散相液滴的Sauter平均粒径为330 μm。采用Mixture多相流模型对聚碳酸酯液液静态分离器进行了模拟和分析。对平行板、波纹板和斜板进行了比较

得出斜板更适合聚碳酸酯液液分离。考察了斜板长、板间距、倾斜角度、入口流量对液液分离效果的影响

得出对于水油相体积比为0.6的物料

最优的聚结板参数为斜板倾角20°、板长0.8 m、板间距40 mm、筒内最大流速5.3×10-3 m·s-1。设计了聚碳酸酯液液分离器

进行了中试试验

水油两相出口浓度接近各自的溶解度值

筒内最大流速为3.9×10-3 m·s-1

结果表明该分离器起到了很好的液液分离效果

可以取代原有的碟片离心机设备

降低了设备和操作费用。

Abstract

The calculated Sauter average drop size of the dispersed phase is 330 μm in the liquid-liquid static settlement experiment for the polycarbonate mixture.The liquid-liquid separation process is simulated and analyzed using mixture multiphase flow model.Different types of coalescence plates are compared

including parallel plates

corrugated plates and inclined plates.The results show that inclined plates are more suitable to the polycarbonate liquid-liquid separation.For the water-oil volume ratio of 0.6

the optimal parameters for the inclined plates are:inclined angle 20°

board length 0.8 m

and plate spacing 40 mm.The maximal flow rate in the separator is 5.3×10-3 m·s-1.According to the calculation results

a polycarbonate liquid-liquid separator is designed and applied in the pilot scale test

which presents a good separation effect.The concentration of water/oil phases is close to the solubility.The maximal material flow rate in the actual liquid-liquid separator is 3.9×10-3 m·s-1.The common disc centrifuges can be replaced by the designed static separators

reducing the cost of equipment and operation greatly.
