Abstract

An ion-exchanged water generating device, comprising an anode (1) and a cathode (2), between the anode (1) and the cathode (2), sequentially comprising from the anode (1) side: an anode chamber (8), an anion exchange Resin chamber (10), bipolar membrane (3), cation exchange resin chamber (11) and cathode chamber (9); Anion exchange resin (6) is filled in the anion exchange resin chamber (10), and anion exchange resin chamber (6) is filled in the cation exchange resin chamber (11) is filled with a cation exchange resin (7), the bipolar membrane (3) includes an anion exchange membrane (3a) and a cation exchange membrane (3b), the anion exchange membrane (3a) is arranged on the anode (1) side, and the cation exchange The membrane (3b) is arranged on the cathode (2) side. Accordingly, it is possible to reduce the amount of water used for regeneration without using a large amount of chemicals or salts for regeneration of the ion exchange resin, and to greatly reduce the cost required for regeneration of the ion exchange resin.

Description

technical field [0001] The present invention relates to an ion-exchange water generating device equipped with an ion-exchange resin regeneration device and a method for regenerating the ion-exchange resin thereof, and more specifically, relates to an ion-exchange water generating device and a method for regenerating the ion-exchange resin thereof, wherein This ion-exchanged water generating device is equipped with H + ion or OH - Ions are used to regenerate ion exchange resins. Background technique [0002] Many proposals propose the use of ion exchange resins in pure water generators or soft water generators. For example, a cation exchange resin is used in a soft water generating device, and the hardness component Ca contained in raw water is converted by the cation exchange resin. 2+ ion or Mg 2+ Ion replacement (ion exchange) to Na + ion or H + ions, etc., thus making soft water. [0003] However, when the exchange group Na of the cation exchange resin + ion or H ...
