Description

Desalination and hybrid device and method {DESALTING AND POWER GENERATING HYBRID DEVICE AND METHOD}

The present invention relates to a desalination power generation hybrid device and method, which is integrated with reverse electrodialysis (RED) and capacitive deionization (CDI) or electrodialysis (ED, Electrodialysis) capable of simultaneous desalination and electricity production. By connecting the reverse osmosis module to the rear end of the device, the present invention relates to a desalination power generation hybrid apparatus and method capable of continuously performing concentration difference generation and seawater desalination.

Reverse electrodialysis (RED) refers to the recovery of salinity or concentration difference energy generated in the process of mixing two different concentration fluids, for example, seawater and fresh water, in the form of electrical energy.

More specifically, reverse electrodialysis (RED) is a system for generating a salt difference using sea water and fresh water, and due to the concentration difference between sea water and fresh water, ions move through an ion exchange membrane (cation exchange membrane and anion exchange membrane), and a plurality of ions It generates a potential difference between electrodes (positive electrode and negative electrode) at both ends of the stack in which the exchange membranes are alternately arranged, and generates electric energy through a redox reaction on the electrodes.

In other words, it is a power generation method that directly converts chemical energy generated as ions dissolved in seawater (salt water) into fresh water through ion exchange membranes into electrical energy. Almost none, it is a power generator with a utilization rate of 90% or more.

On the other hand, a capacitive desalination (CDI) process is a technique of removing ions by using an adsorption reaction of ions due to electrical attraction generated in an electric double layer formed on the electrode surface when a potential is applied to the electrode.

More specifically, the capacitive desalination process removes ionic substances in the influent water by adsorption reaction in an electric double layer formed on the electrode surface when an electrode potential of 1 to 2 volts (V) is applied, and the adsorbed ions are stored in the electrode. When the capacity is reached, the electrode potential is switched to zero volts (V) or the opposite potential to desorb the adsorbed ions to regenerate the electrode.

The capacitive desalination process operates at a low electrode potential (about 1 to 2 V), and as a result, the energy consumption is much lower than that of other desalination technologies.

However, such a capacitive desalination process was not possible because continuous operation of the desorption process for regenerating the electrode is necessary when ions reach the storage capacity of the electrode.

In addition, a porous carbon electrode is frequently used as an electrode in a capacitive desalination process, in which ions adsorbed to the electrode and ions of opposite charges move to the electric double layer due to the rapid change of electrode potential, and all the ions adsorbed to the hole are desorbed. There is a problem in that it remains on the surface of the electrode to reduce the adsorption efficiency of the electrode.

On the other hand, the electrodialysis (ED) process uses an ion exchange membrane that selectively permeates an electrolyte (positive or negative) having electrical properties among chemical components dissolved in water when an electric potential is applied to the electrode. To separate the ionic materials.

More specifically, by applying electric power to the electrode, the cation or anion dissolved in the water moves to each electrode side, so that a desalting chamber in which the ion concentration decreases and a concentration chamber in which the ion concentration increases are alternately formed.

However, such a desalination process using electrodialysis has the disadvantage of consuming energy because the electrode needs to be powered.

In addition, the reverse osmosis (RO) process is a process in which water contained in a high concentration solution moves to a low concentration solution through a semipermeable membrane, and desalination is performed.

Although these technologies are currently being published as a new renewable energy source, various research reports and papers have been published. However, the electrochemical potential energy generated during the operation of reverse electrodialysis (RED) devices is controlled by capacitive desalination (CDI) or electrodialysis (ED) operation. By linking the reverse osmosis (RO) process in the subsequent stage, the linkage system that can desalination of seawater or brackish water while simultaneously reducing the energy required for the desalination process has not been reported.

First, referring again to FIG. 2, the first high concentration solution and the first low concentration solution are introduced into the first and second reverse electrodialysis power generation units 100 and 200 through the first and second supply units 401 and 402, respectively. When the high concentration solution flows into the desalination flow path 310, a potential difference is generated by the concentration difference between the first high concentration solution and the first low concentration solution in the first and second reverse electrodialysis generators 100 and 200.

Accordingly, the flow of electrons occurs in the first and second anode electrodes 101 and 201 and the first and second cathode electrodes 102 and 202.

The flow of electrons as described above means that a potential is applied to the desalination flow path 310 defined as a space between opposite surfaces of the first cathode electrode 102 and the second anode electrode 201.

That is, the desalination process can be performed.

Since the desalination unit 300 of the desalination-generation unit 1000 configured as described above does not need an additional electrode for desalination, there is an effect that a more compact device can be realized.

In addition, since the potential applied to the desalination unit 300 is electricity produced by the first and second reverse electric dialysis generators 100 and 200, there is an effect of producing fresh water without using additional energy.

The deionization passage 330 and the concentrated passage 340 may be divided by the third ion exchange membrane 320.

More specifically, the ionic material of the first high concentration solution introduced into the desalting unit 300 ′ may be formed of the first cationic material by the electricity produced at the first cathode electrode 102 and the second anode electrode 201. It moves toward the cathode electrode 102 and passes through the cation exchange membrane 321.

At the same time, the anionic material moves toward the second anode electrode 201 and passes through the anion exchange membrane 322.
