    摘要: The present invention provides an apparatus for recovering a polymer from polymer solution, and a method of recovering a polymer using the apparatus. The apparatus includes a polymer solution-storage tank for storing a polymer solution; a polymer solution feeding pump for pumping the polymer solution from the polymer solution storage tank; an antisolvent storage tank for storing an antisolvent; an antisolvent feeding pump for pumping the antisolvent from the antisolvent storage tank; a reaction chamber to which the polymer solution pumped by the polymer solution feeding pump and the antisolvent pumped by the antisolvent feeding pump are supplied; a high-speed mixer that is rotated in the reaction chamber at a speed range of 1000 to 30000 rpm, mixes the polymer solution with the antisolvent under a shearing force corresponding to a tip speed of 5 to 30 m/sec, and precipitates a polymer; and a precipitate storage tank for storing the precipitation mixture of the polymer and the solvent/antisolvent.
