MECHANICALLY AGITATED, INNER CIRCULATION REACTOR FOR RESIN ION EXCHANGE AND ADSORPTION

摘要

Disclosed is an internal circulation resin ion exchange adsorption reactor with a mechanical stirrer. The upper part ⅔˜⅘ of the reactor main body is an open cylinder and the lower part 1/5˜⅓ is a cone-shaped body with a slope of 30°±10°. A bell-jar shaped reaction slot with a turbine water stirrer inside is located in the center of the reactor main body. The reactor main body is equipped with a cylindrical guide plate. A water collection weir, an inclined tube separator and an annular resin collection hopper are located between the shell of the reactor main body and the guide plate. The reactor is equipped with a water inlet pipe and a water outlet pipe. A resin removal pipe is connected with the annular resin collection hopper and a resin desorption slot respectively, and a regenerated resin reflux pipe is connected to the bell-jar shaped reaction slot.

1. A mechanically agitated, inner circulation reactor for resin ion exchange and adsorption, wherein an upper ⅔˜⅘ part of a main body of the reactor is a cylinder with an open upper end and a lower ⅕˜⅓ part of the reactor is a cone with a slope of 30°±10°; in a middle of the reactor is a bell-type reaction tank, which is equipped with a turbine water-lifting agitator; a cylindrical guide plate is also designed within the reactor; between the guide plate and a casing of the main body the reactor are installed with an outlet weir and an inclined pipe separator; at the lower part of the same space, between the guide plate and the main body casing of the reactor, stands a circular resin-collecting sump; an inlet pipe extends into the reactor and stops near a conical frustum, a lower part of the bell-type reaction tank; an outlet pipe is designed near the outlet weir; a resin discharge pipe connects the circular resin-collecting sump and a resin desorption tank together, and a return pipe that channels the regenerated resin back into the lower part of the bell-type tank and stops near the conical frustum;
wherein the bell-type reaction tank is a hollow rotary assembly concentric with the main body of the reactor; an upper ⅓˜½ part is a hollow cylinder and a lower ½˜ 1/3 part is a hollow conical frustum; a bottom of the bell-type reaction tank is 0.2˜0.8 m above a bottom of the main body of the reactor, while a top of the bell-type reaction tank is 0.5˜1.0 m below a top of the main body of the reactor; a diameter of the hollow cylinder of the bell-type reaction tank is ⅕˜⅓ of a diameter of the main body of the reactor, so is a diameter of the upper end of the conical frustum; a diameter of the lower end of the conical frustum is ¼˜½ of the diameter of the main body of the reactor; a baffle plate is located between the hollow cylinder and the conical frustum; a hole is punched out at a center of the baffle plate and a diameter of the baffle plate is ¼˜½ of the diameter of the hollow cylinder of the bell-type reaction tank.
