CONDENSED WATER DESALTING APPARATUS

摘要

PROBLEM TO BE SOLVED: To prevent the lowering of the desalting capacity of the ion exchange resin in a condensed water desalting tower while ensuring the healthiness of water quality. SOLUTION: A resin keeping tank 29 is connected to a condensed water desalting tower 15 through a resin supply piping 30. A org. impurity (TOC). removing apparatus 37 is connected to the resin keeping tank 29 through a keeping water guide pipe 33. TOC eluted during keeping is adsorbed by an anion resin and an anion resin bed is provided in the lower part of the mixed bed of the anion resin and cation resin in the condensed desalting tower 15 and TOC eluted from the cation resin of the mixed bed is caught by the lower anion bed.
