Modular fiber coalescence liquid-liquid separation system

The utility model relates to a mixed liquid separation system, and provides a modularized fiber coalescence liquid-liquid separation system which comprises a liquid conveying device used for conveying mixed liquid and a plurality of fiber coalescence separation modules, and each fiber coalescence separation module comprises a fiber coalescence device used for demulsification coalescence and a separation device used for settling separation. A liquid outlet of the fiber coalescence device is connected with a liquid inlet of the separation device, the liquid conveying device is sequentially connected with the multiple fiber coalescence separation modules, and the separation precision of the fiber coalescence separation module located at the upper stage is larger than that of the fiber coalescence separation module located at the lower stage. According to the modularized fiber coalescence liquid-liquid separation system, the separation rate of a mixed liquid phase can be improved, and a good separation and blocki
