Description
Technical field
The utility model relates to a kind of product water device, particularly uses cation and anion exchange (EDI) module to carry out cation and anion exchange (EDI) the continuous circulation device that continuous circulation produces water.
Background technology
Ion exchange resin fills to be clipped between anion/cation exchange membrane and forms cation and anion exchange (EDI) unit by cation and anion exchange (EDI) device.Separate between cation and anion exchange (EDI) unit of some amount by reticulation in cation and anion exchange (EDI) assembly, form deep or light hydroecium.Again Yin/Yang electrode is set at unit group two ends.Under galvanic promotion, be each passed through anion and cation exchange membrane by the zwitterion in freshwater room current and enter into dense hydroecium and remove at freshwater room, and take ion out of system by the water of dense hydroecium, become dense water.
Cation and anion exchange (EDI) equipment generally feeds water using reverse osmosis (RO) pure water as cation and anion exchange (EDI).RO water outlet resistivity is generally 1 ~ 20 μ S/cm (25 DEG C).Cation and anion exchange (EDI) water outlet resistivity can up to more than 15M Ω .cm (25 DEG C), but arrange according to deionized water purposes and system configuration, cation and anion exchange (EDI) pure water is applicable to prepare the pure water of resistivity requirement at 5-18.2M Ω .cm (25 DEG C).
