Title:
イオン交換樹脂再生装置
Document Type and Number:
Japanese Patent JP7215094
Kind Code:
B2
Abstract:
To provide a regeneration device for ion exchange resins capable of reducing the turbulent flow of a back washing water in the vicinity of a resin separation boundary face to improve a resin separation precision.SOLUTION: In an ion exchange resin regeneration device for condensate demineralization, a condensate demineralizing tower 1, cation exchange resin regeneration tower 3, anion exchange resin regeneration tower 5 and resin storage tank 8 are connected by pipe arrangement to enable a resin transfer. In the device, an anion exchange resin outlet 20 is provided on the way in a cation exchange resin regeneration tower 10, and a pipeline 31 is connected to the outlet via the branch pipelines 30. Besides, an anion exchange resin extraction pipeline 35 is branched from the pipeline 31, and a chemical-feeding pipeline 36 is connected to the pipeline 31.SELECTED DRAWING: Figure 1
