    • An electric deionized water production apparatus in which a direct current field is applied to a deionizing chamber packed with an ion-exchange material such that ions to be discharged are allowed to migrate in the direction identical or opposite to the direction of the water flow in the ion-exchange material, whereby ionic impurities adsorbed in the ion-exchange material are discharged from the system, the ion-exchange material being a mixture of a monolith-shaped organic porous ion-exchange material and ion-exchange resin particles. The electric deionized water production apparatus has a simple structure that can reduce material cost, process cost, and assembly cost, capable of accelerating migration of the adsorbed ionic impurities to facilitate discharge of the adsorbed ions and free from a deflected flow due to swelling or shrinkage accompanying an ion-exchanging reaction, and from poor contact with an ion-exchange membrane.
    • 一种电去离子水生产装置,其中直流电场施加到装有离子交换材料的去离子室,使得排出的离子允许沿与水流中的水流方向相同或相反的方向迁移 离子交换材料,其中吸附在离子交换材料中的离子杂质从系统中排出,离子交换材料是整料形有机多孔离子交换材料和离子交换树脂颗粒的混合物。 电去离子水生产设备具有简单的结构,其可以降低材料成本,工艺成本和组装成本,能够加速吸附的离子杂质的迁移,以促进吸附的离子的排出并且由于膨胀或收缩而没有偏转的流动 伴随着离子交换反应,并且与离子交换膜接触不良。
