continuous counter-flow extraction 连续逆流浸取
multilevel counter-flow extraction 多级逆流浸出
Multi-plate counter-flow extraction tower and the liquid-liquid equilibrium pot were designed. Experiments of counter-flow extraction and cross-current extraction were conducted, considering influencing factors such as solvent ratio,stirring velocity, raw material concentration and extraction plates.
考察了溶剂比、搅拌速度、原料浓度及萃取级数等因素对错流及逆流萃取的影响，改进并设计了新型的逆流萃取小试塔，进行了错流和逆流萃取实验；以UNIQUANC方程为平衡模型，分别采用相分配系数法和逐板计算法模拟计算错流和逆流萃取结果，实验结果和关联结果误差较小。
