Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described. In adding reference numerals to components of the following drawings, it is determined that the same components have the same reference numerals as much as possible even if displayed on different drawings, and it is determined that they may unnecessarily obscure the subject matter of the present invention. Detailed descriptions of well-known functions and configurations will be omitted.

The present invention provides a method for constructing a stacked fluidized bed deionization device having an increased capacity by repeating unit cells.

First, the fluidized-bed capacitive deionization (FCDi) (1) is newly proposed by the inventor in Korean Patent Application No. 1020100078543, and uses a fixed electrode of conventional CDI (Capacitive Deionization) technology. It is a method that can be concentrated to a high concentration by changing to a flow electrode.

As shown in FIG. 1, the fluidized-phase capacitive deionization apparatus 1 has a positive electrode active material 12 flowing between the positive electrode current collector 11 and the positive electrode channel 14 formed between the positive electrode separation membrane 13. And a fluidized bed cathode 20 having a phase anode 10 and a cathode active material 22 flowing through a cathode flow passage 24 formed between the anode current collector 21 and the cathode separator 23. As the electrolyte 30 flows through the electrolyte passage 34 formed between the separator 13 and the cathode separator 23, ions may be moved from the electrolyte 30 to concentrate the electrolyte solution.

The positive electrode current collector 11, the negative electrode current collector 21, the positive electrode separator 13, and the negative electrode separator may be used as long as they have been used in a conventional fluidized electrode system (battery, battery, etc.). It is possible, and those skilled in the art can appropriately select and use according to the purpose and conditions of use.

Electrode materials such as the positive electrode active material 12 and the negative electrode active material 22 may be porous carbon (activated carbon, carbon fiber, carbon aerogel, carbon nanotube, etc.), graphite powder, metal oxide powder, or the like. Can be used in a fluidized state. The positive electrode active material and the negative electrode active material may be different materials, but the same material may be used.

The width of the anode channel 14 and the cathode channel 24 may be formed to be equal to or less than an interval between the electrode current collector and the separator in the conventional fluidized bed electrode system. This is because there is a problem that the size of the fluidized bed electrode system is large when the electrode active material is fixed to secure the capacity of the active material required for charging and discharging, and there is a limitation in the distance between the electrode current collector and the separator in which the active material is filled. In the fluidized-phase capacitive deionization apparatus 1, since the electrode active material can be continuously supplied, the design can be freely changed according to the purpose of use, the active material, the electrolyte, and the like without such limitation. Therefore, according to one embodiment of the present invention, the width of the anode flow passage 14 and the cathode flow passage 24 may be used in a size of several tens of micrometers to several mm. Likewise, the width of the electrolyte flow path 34 can likewise be supplied continuously with electrolyte, so that the design can be appropriately changed without limitation due to the size of the fluidized bed electrode system.

The anode separation membrane 13 and the cathode separation membrane 23 may be microporous insulation separation membranes or ion exchange (conduction) membranes. The anode separation membrane 13 and the cathode separation membrane 23 are provided for electrophysical separation, and the micropore insulation separator can only move ions, and the ion exchange membrane is a cation or anion. Only anions can be moved selectively.

Thus, for example, when the concentrated water is passed through the electrolyte channel 34 of the fluidized electrode system 1 in which the potential difference is generated through a supply means (not shown), the electrolyte 30 is desalted (deionized) to be concentrated water. Since the electrolyte in the inside is separated into the positive electrode channel 14 and the negative electrode channel 24 may be desalination. Therefore, compared to the conventional evaporation method or reverse osmosis (RO) method, water treatment is possible at a very low energy cost, and large capacity is possible.

Based on this working principle, the stacked fluidized bed capacitive deionization apparatus (100, 102, 104, 106, 108) according to the present invention will be described.
