Abstract
PURPOSE: To reduce the installation space for a regenerating device by regenerating the used ion exchange resins by separating the same to cation exchange resins and anion exchange resins respectively and mixing these in one of regeneration towers.
CONSTITUTION: The used ion exchange resins in a mixed bed type desalting tower 1 are transferred via an outlet pipe 14 and an inlet pipe 4 into a cation regenerating tower 2. Anion exchange resins and cation exchange resins are separated with differences in specific gravity by the backwashing water from a backwashing water tank 13. The anion resins in the upper layer are transferred via a transfer pipe 5 and an inlet pipe 6 into an anion regenerating tower 3. In the respective towers 2, 3, the resins are backwashed by the mixed flow of the backwashing water and the pressurizing air from an air storage tank 17, and are regenerated by chemicals. Thence, the anion exchange resins are returned through an outlet pipe 7 and an inlet pipe 4 into the tower 2. Here, these are mixed by the pressurizing air, and while the mixed state is maintained, the resins are transferred via an outlet pipe 8 and an inlet pipe 9 into the tower 1, where they are reused.
