Abstract
PURPOSE:To obtain high-purity pure water from the title demineralizer by providing a water collector at a position higher than the upper surface of the resin bed of the cation exchange tower and anion exchange tower. CONSTITUTION:Raw water is supplied from the bottom of the cation exchange tower through a raw water pump 2 and a pipeline 14, and the waste liq. contg. the suspended matter accumulated in the resin is discharged from a pipeline 15. Decarbonated water from a decarbonated water tank 7 is supplied to the anion exchange tower from the bottom through a decarbonate water pump 8 and a pipeline 16, and the waste liq. is discharged from a pipeline 17. Water is injected into the respective water collectors through pipelines 18 and 19 to prevent the clogging of water collector nozzles during back washing. In the regeneration stage, the hydrochloric acid in a hydrochloric acid measuring tank 20 is sent to the cation exchange tower 4 by the ejector 22 using the decarbonated water from a pipeline 21 through a pipeline 23, and the cation- exchange resin is regenerated. In addition, the sodium hydroxide in a sodium hydroxide measuring tank 26 is sent to the anion exchange tower 10 by an ejector 27 using pure water through a pipeline 28.
