Abstract

The invention discloses a capacitive deionization device for removing various ions in water. An anode chamber (3) and a cathode chamber (7) are connected and closed up and down through threads to form a sandwich structure; the anode chamber (3) is separated from the cathode chamber (7) by a spacing ring (5); a capacitive deionization electrode is of a disc-shaped integral structure formed by compounding a circular mesh electrode and a carbon aerogel circular ring, and the outer diameter of the circular mesh electrode is matched with the inner diameter of the carbon aerogel circular ring; the circular mesh electrode (401) is made of foamy copper, and the surface and the interior of the foamy copper are filled with carbon aerogel; the spacing ring (5) is formed by combining an upper gasket (501), an ion exchange membrane (502) and a lower gasket (503) from top to bottom; and the specific surface area of the carbon aerogel is greater than or equal to 680m < 2 > / g. The capacitive deionization device has the advantages that the installation is simple, the sealing performance is excellent, use of a binder and a conductive agent is avoided, and the like, and the device can be used for removing various ions such as sodium, calcium, magnesium, fluorine and the like in water.

Description

technical field [0001] The invention belongs to the technical field of capacitive deionization, and specifically relates to a capacitive deionization device for removing various ions in water, which can be used for removing various ions such as sodium, calcium, magnesium, and fluorine in water. Background technique [0002] Current ion removal technologies mainly include reverse osmosis, electrodialysis, and multi-stage flash evaporation, etc., but the disadvantages of high cost, high energy consumption, and secondary pollution limit the application range of this technology, and capacitive deionization technology (CDI), due to Its outstanding features such as low cost, low energy consumption, and little environmental pollution have attracted more and more attention. Capacitive deionization technology is based on the theory of electric double layer capacitance. Under the action of an external electric field, the anion and cation in the solution are adsorbed to the surface of ...
