TRANSPORTING METHOD FOR USED ION EXCHANGE RESIN
PURPOSE:To reduce an amt. of radioactive liquid waste product by discharging both of used ion exchange resin and transporting water for the ion exchange resin from an ion exchange tower into a tank, separating the used ion exchange resin from the water in the tank, and injecting the separated transp...

| description | PURPOSE:To reduce an amt. of radioactive liquid waste product by discharging both of used ion exchange resin and transporting water for the ion exchange resin from an ion exchange tower into a tank, separating the used ion exchange resin from the water in the tank, and injecting the separated transporting water into the ion exchange tower again. CONSTITUTION:An ion exchange resin tower is drained by opening a vent valve 4 and a drain valve 5 after closing an inlet valve 2a and an outlet valve 3a of treating water for the ion exchange tower 1. The drain is stored in a tank 12 after passing through a temporary pipe 19. After closing valve 4, 5, a discharge value for waste resin 7a is opened. Then, a backwashing water valve 8 and an inlet valve 9a for compressed air are opened. Thus, the ion exchange resin on an ion exchange resin bed 6 held on a screen 10 is loosened by the backwashing water pressurized by a pump 13 and fluidized. The whole part of the ion exchange resin bed 6 is pushed from above by the pressurized air supplied from a valve 9a and the resin is collected in a vessel 11 in the form of a slurry through a valve 7a. On one hand, transporting water for the resin is stored in a tank 12 through a mesh 16 and reused by a pump 13. |
