The invention discloses a fixed bed counter-current regeneration device for ion exchange resin and the method of use, relates to the field of ion exchange resin regeneration. The device comprises a cyclone separator, a regeneration reactor, a fully mixed resin reactor, a desorption solution storage tank, and a regenerant storage tank, wherein the cyclone separator is placed on top of the regeneration reactor, the upper part of the cyclone separator is connected to the fully mixed resin reactor. A resin inlet is provided at the bottom of the cyclone separator, a resin bed and a resin filter are arranged inside the regeneration reactor, a resin outlet and a regenerant inlet are arranged at the bottom of the regeneration reactor, the resin outlet is connected to the fully mixed resin reactor, the regenerant inlet is connected to the desorption solution storage tank and the regenerant storage tank, respectively, one side of the regeneration reactor is further provided with a regenerant outlet, and the regenerant outlet is connected to the desorption solution storage tank. The invention effectively improves resin regeneration efficiency via separator and counter-current, reduces the desorption solution yield, prevents mechanical wear and tear of the resin, and can be used as part of large-scale ion exchange resin applications.
