[0002] The traditional capacitive deionization device is to place one or several pairs of adsorption electrodes placed in parallel between two capacitive deionization modules, so that the capacitive deionization device is placed in the water flow. When the water flows through the adsorption electrodes, the ions in the solution will Adsorbed on the electrode, reducing the concentration of the solution, this method will increase the internal resistance of the entire electrode, resulting in high operating costs
In addition, due to the gravity of the water itself, the water flow cannot cover the entire electrode, resulting in a decrease in the effective contact area of the electrode.

A capacitor deionization device comprises electrode pairs, electrode pair supporting frames, an organic glass container, a collector electrode for power on, a water inlet pipe for being connected to a raw water pond and a water outlet pipe for being connected to a purified water pond.Each electrode pair supporting frame comprises a first electrode placement face, a second electrode placement face opposite to the first electrode placement face, a water inlet and a water outlet.All the electrodes and all the electrode pair supporting frames are located inside the organic glass container.The organic glass container is a sealing container with the thick inner wall.The water inlet pipe penetrates through the organic glass container to be communicated to the water inlets.The water outlet pipe penetrates through the organic glass container to be communicated to the water outlets.When the capacitor deionization device is filled with water to be treated, after the collector electrode making contact with the water to be treated is powered on, capacitor deionization operation is performed on the water to be treated through the capacitor deionization device.The embodiment of the invention further provides a capacitor deionization system and method.
Description
technical field [0001] The invention relates to the technical field of capacitive deionization, in particular to a capacitive deionization device, system and capacitive deionization method. Background technique [0002] The traditional capacitive deionization device is to place one or several pairs of adsorption electrodes placed in parallel between two capacitive deionization modules, so that the capacitive deionization device is placed in the water flow. When the water flows through the adsorption electrodes, the ions in the solution will Adsorbed on the electrode, reducing the concentration of the solution, this method will increase the internal resistance of the entire electrode, resulting in high operating costs. In addition, due to the gravity of the water itself, the water flow cannot cover the entire electrode, resulting in a decrease in the effective contact area of the electrode. Contents of the invention [0003] In view of this, it is necessary to provide a ...
