イオン交換樹脂再生装置および再生方法
Document Type and Number:
Japanese Patent JP6776926
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an ion exchange resin regeneration apparatus and method which prevent a cation exchange resin from being mixed into an anion exchange resin regeneration tower to prevent the reverse regeneration of the cation exchange resin and improve the utilization efficiency of the ion exchange resin.SOLUTION: In an ion exchange resin regeneration apparatus for a condensate where a condensate demineralization tower 1, a cation exchange resin regeneration tower 3, an anion exchange resin regeneration tower 5, and a resin storage tank 8 are connected by pipes 2, 4, 6, 7, 9 so that ion exchange resins can be transferred, an on-off valve 15 is provided in the resin transfer pipe 4 for connecting the cation exchange resin regeneration tower 3 and the anion exchange resin regeneration tower 5 to each other, and a return water supply pipe 14 for returning the ion exchange resin mixed in the resin transfer pipe 4 to the cation exchange resin regeneration tower 3 is connected to the upstream side of the on-off valve 15 in the resin transfer pipe 4.SELECTED DRAWING: Figure 1
