    Description Of  liquid liquid centrifugal extractors

    The centrifugal extractor is a new, fast and efficient liquid-liquid extraction and separation equipment. It has higher separation efficiency than traditional extraction equipment such as mixer settler and extraction towers, and is more conducive to continuous production.

    A Counter-Current multiple stage Liquid–Liquid Centrifugal Extractor is a high-efficiency separation device designed for rapid and continuous extraction between immiscible liquid phases. By combining intense mixing and high-speed centrifugal separation in one compact unit, it significantly improves mass transfer efficiency and phase disengagement compared with traditional mixer settlers.

    The centrifugal extraction machine can be used as a single unit or can be connected in multiple stages to achieve counter-current extraction. It has high mass transfer efficiency, short two-phase residence time, low retention volume, and is easy to operate. The rotation speed, flow ratio and mixing intensity can be changed as needed.

    Working Process Of  liquid liquid centrifugal extractors
    1. Mixed mass transfer process
    The light and heavy phase solutions enter the mixing chamber from the light phase inlet and heavy phase inlet in a certain proportion, and the mixing and mass transfer process is quickly completed under the action of the stirring paddle.
    2. Two-phase separation process
    The mixed liquid enters the drum under the action of the static turbine. In the cavity area formed by the web, the mixed liquid quickly rotates synchronously with the drum. Under the action of centrifugal force, the heavy phase liquid with high density gradually moves away during the upward flow process. The center of the drum moves toward the drum wall; the light phase liquid with low density gradually moves away from the drum wall and toward the center. The clarified two-phase liquid finally enters the collection chamber through each channel and flows out along the tangent square, completing the two-phase separation. process.

    How Multiple stage liquid liquid centrifugal extractors work?

    In counter-current mode, the aqueous and organic phases flow in opposite directions through multiple stages. Inside each centrifugal extractor:
    • Liquids are intensively mixed in a rotating mixing zone.
    • The mixture enters a high-speed centrifugal separation zone.
    • The two phases are quickly separated under strong centrifugal force.
    • Each phase flows to the next stage in counter-current configuration.
    • This design ensures maximum mass transfer efficiency and minimal solvent loss.

    Features Of Multiple stage liquid liquid centrifugal extractors
    • Simple and stable structure: top-suspended structure, no bottom bearings, and no risk of leakage;
    • High extraction efficiency: the independent mixing chamber and stirring paddle can be replaced according to the requirements of the mixing system;
    • Energy saving: non-annular mixing structure, the drum itself does not participate in mixing, low energy consumption and can effectively avoid the emulsification phenomenon caused by over-mixing;
    • Corrosion resistance: The material can be made of stainless steel metal materials or non-metallic composite materials;
    • Good sealing performance: multi-channel shaft seal design, optional magnetic transmission structure.
