A new liquid-liquid countercurrent extractor with Taylor-Couette flow was proposed and following three research subjects to improve the extraction performance were studied(1) Increasing the stability of oil-water countercurrent flow(2) Highly efficient extraction using oil-water emulsion(3) Scale-up of extractor and feasibility of total extraction processAs a result, we made clear the chemico-physical properties of oil phase, water phase and inner rotor surface, which were required for the formation of suitable countercurrent flow with highly dispersed oil. By stabilizing the Taylor-Couette flow with oil-water emulsion by the addition of a small amount of PEG(poly-ethyleneglycol), the high-speed extraction with high theoretical stages more than 10 stages were attained. Finally the scale-up tests were carried out. By the use of larger extractor, the increase of theoretical stages was observed for the positive extraction and the high recovery rate for the back extraction

提出了一种新型Taylor-Couette流液液逆流萃取器，并针对提高萃取性能进行了以下三个研究课题（1）提高油水逆流稳定性（2）油水乳状液高效萃取（ 3）萃取器的放大和整个萃取过程的可行性由此，我们明确了油相、水相和内转子表面的化学物理性质，这是在高度分散的油中形成合适的逆流所需要的。通过添加少量PEG(聚乙二醇)来稳定油水乳化液的Taylor-Couette流，实现了10级以上高理论级数的高速萃取。最后进行了放大试验。通过使用更大的萃取器，正萃取理论级数增加，反萃取回收率高
