Abstract:
A liquid-liquid-liquid three-phase continuous and countercurrent extraction apparatus comprises a three-phase-mixing chamber, a three-liquid-flow settler, and a two-phase-mixing chamber; a liquid-flow control separator placed in the three-liquid-flow settler aims to flexibly regulate the directions of three liquid flows in the three-phase system by different control separator combinations to achieve either a countercurrent operation of the top-layered phase with the middle-bottom two-layered mixtures, or a countercurrent operation of the top-middle two-layered mixtures with the bottom-layered phase; and a method of using the same, relating to extraction and separation field of chemical technology.
