PARTIAL RESIN REGENERATION TYPE CONDENSED WATER DESALTING APPARATUS

摘要

PURPOSE:To regenerate only the resin of the upper part of a mixed resin tank by drawing out only the upper part of the mixed resin of the tank in the title apparatus wherein a container main body having a raw solution inlet and a treated solution outlet and a resin tank wherein a cation resin and an anion resin are mixed in a container are provided. CONSTITUTION:A condensed water desalting apparatus for treating the condensed water from the condenser of an atomic power plant has a desalting tower 1 to which condensed water is guided through a pipe 21 and an inlet valve 22 and condensed water is subjected to desalting treatment by a mixed resin 10 of a cation resin and an anion resin to be sent to a downstream system through an outlet valve 23 and a pipe 24. When the whole quantity of the resin is regenerated, the respective resins are regenerated in a cation regeneration tower 2 and an anion regeneration tower 3 to be returned to the desalting tower 1 through a resin storage tank 4. In this case, the taking-out system 42 of the intermediate part resin of the bed-shape mixed resin 10 of the desalting tower 1 and a resin pushing water system 54 are provided and an anion resin taking-out system 44 after partial resin separation is provided to the cation regeneration tower 2.
