Rotary type capacitive deionization apparatus

A capacitive deionization apparatus comprising:

• a capacitive adsorption module assembly comprising a plurality of capacitive adsorption modules, each of the plurality of capacitive adsorption modules comprising:
• a disk-shaped spacer configured to form a flow path through which feed flows;
• a cation exchange membrane attached to any one of an upper surface and a lower surface of the spacer;
• a first electrode attached to the cation exchange membrane;
• an anion exchange membrane attached to the other of the upper surface and the lower surface of the spacer;
• a second electrode attached to the anion exchange membrane;
• and
• a rotary shaft inserted through the stacked capacitive absorption modules,
• wherein the capacitive adsorption modules are vertically stacked such that adjacent capacitive adsorption modules share or contact the first electrode or the second electrode, and
• wherein at least one first terminal and second terminal passing through the stacked capacitive adsorption modules are provided, and wherein the first terminal is electrically connected to the first electrode of an odd-numbered capacitive adsorption module, and the second terminal is electrically connected to the second electrode of an even-numbered capacitive adsorption module,
• a casing hermetically accommodating the capacitive absorption module assembly and having a feed passage;
• a power source configured to supply DC power to both ends of the rotary shaft protruding to an outside of the casing;
• and
• a rotary driving unit configured to drive the rotary shaft.
