CDICapacitive deionization apparatus using electrification electric charging phenomenon

摘要

The present invention improves the arrangement and stacking structure of the electrodes so as to minimize contact points for applying power between electrodes, thereby facilitating assembly, improving work efficiency, securing simplicity and diversity of an external power supply device for supplying power to the electrodes The present invention relates to a CDI apparatus using a charging principle capable of increasing current efficiency, in which two or more unit storage deionization modules in which a plurality of electrodes are stacked in a vertical direction are arranged side by side, In the CDI device including the power supply unit, each outermost unit storage deionization module is composed of one electrode, and the first electrode part and the two electrodes, to which power is supplied from the power supply part, are separated by the graphite connection part So that one electrode is interposed between the electrodes of the adjacent other unit storage deionization modules The second electrode portions to be disposed are alternately stacked so that electric charges are alternately charged between the electrodes facing each other in the upper, lower, left, and right directions.
