Patent ID: 8758608

Claim:
A continuously flowing, inner circulatory, quasi-fluidized-bed reactor for resin ion exchange and adsorption, comprising: a main body casing, an inclined pipe separator, an outlet weir, an inlet pipe and an outlet pipe, a reducing fluidization tank, a guide plate, a resin regeneration tank, a resin discharge pipe, a return pipe for regenerated resin and a distributing ejector; wherein the inlet pipe and the distributing ejector are designed at a bottom of the main body casing; the distributing ejector connects to the inlet pipe on one side, and to a lower end of the reducing fluidization tank concentrically located inside the main body casing on the other side; the guide plate is placed between the main body casing and the reducing fluidization tank, and the inclined pipe separator is installed between the main body casing and the guide plate; the outlet weir is located above the inclined pipe separator and connects to the outlet pipe; the resin regeneration tank connects to a lower part of the reactor via the resin discharge pipe and to the reducing fluidization tank via the return pipe for the regenerated resin; wherein an upper ⅔˜¾ part of the main body casing is a cylinder with an open upper end; a lower ⅓˜¼ part of the main body casing is an inverted cone, the slope of which is 35°±10°; wherein the reducing fluidization tank is a hollow rotary assembly concentric with a main body of the reactor; a bottom of the reducing fluidization tank is 0.2˜0.8 m above a bottom of the main body casing while a top is 0.5˜1.0 m below a top of the main body casing; a lower ¼˜⅓ part of the reducing fluidization tank is a hollow cylinder, while an upper ¾˜⅔ part of the reducing fluidization tank is a hollow conical frustum; a diameter of the cylindrical part is ⅕˜⅓ of a diameter of the reactor, so is a diameter of a lower end of the conical frustum; a diameter of an upper end of the conical frustum is ¼˜½ of the outer diameter of the reactor.
