One of the two sets of storage tanks is an organic phase storage tank and the other one of the two sets of storage tanks is an aqueous phase storage tank. The organic phase storage tank is communicated with the upper portion of the extraction column through an organic phase metering pump and an organic phase feed pipeline, and the aqueous phase storage tank is communicated with the lower portion of the extraction column through an aqueous phase metering pump and an water inlet pipeline. The upper portion of the extraction column is connected into the waste water barrel through a water outlet pipe, and the lower portion of the extraction column is connected into the production barrel through a discharge pipe. The system is used to extract ionic liquid, and the production rate reaches to over 80%. The ionic liquid extraction system is high in production efficiency, and can achieve a handling capacity of 1 ton per day. The ionic liquid is fed continuously, and thus the ionic liquid extraction system is suitable for large-scale production. The products are wide in application, and thus the ionic liquid extraction system is suitable for the purification of various ionic liquid.
