Description

Method and apparatus for separating seawater into caustic soda and fresh water using green energy

The present invention relates to a method and apparatus for separating seawater into caustic soda and fresh water using green energy, and more specifically, to generate power by itself through a power generation means and use 3.5% of salt ( By separating the seawater containing Nacl into caustic soda and fresh water, there is no external power supply, eliminating carbon dioxide emissions and fossil fuels that cause global warming, while reducing the enormous cost of caustic soda and fresh water. The present invention relates to a method and apparatus for separating seawater into caustic soda and fresh water using green energy.

Generally, caustic soda (sodium hydroxide) is a representative strong base having the formula NaOH and a molecular weight of 39.997 g / mol, pure caustic soda being white crystals.

The caustic soda absorbs water vapor from the air and melts itself, so it should be kept in contact with air.

In addition, said caustic soda shows strong alkalinity in aqueous solution.

Caustic soda having such properties is widely used as a raw material in the manufacture of pulp, fiber, dye, rubber, soap, etc., and is widely used as a desiccant because it has a strong deliquescent property to absorb moisture in the air.

The caustic soda is prepared by adding a sulfuric acid to the raw material salt, followed by thermal decomposition to prepare caustic soda, and an ammonia soda method of producing caustic soda by reacting soda ash with Ca (OH) 2; And electrolysis methods for producing caustic soda by electrolysis of brine. Currently, electrolysis methods including a diaphragm method and a mercury method ion exchange membrane method are most widely used.

The diaphragm method is a method of preparing caustic soda by installing a diaphragm made of asbestos from the graphite anode and the iron cathode so that combustion from the anode and caustic soda from the cathode do not react.

In addition, the mercury method is a method of preparing caustic soda using mercury as a negative electrode material, which is not currently used due to environmental pollution of mercury, which is a heavy metal.

On the other hand, in the ion exchange membrane method, the ion exchange membrane is installed inside the electrolytic cell, the anode and cathode terminals are installed in the anode and cathode tanks of the electrolytic cell partitioned on both sides, and the brine is used as an electrolyte to supply power to the two electrode terminals. By supplying, chlorine gas is obtained at the positive electrode and hydrogen and caustic soda at the negative electrode.

That is, a certain amount of water is injected into the cathode tank having the anode terminals connected to each other with an osmotic membrane interposed therebetween, and a certain amount of sodium chloride solution is injected into the anode tank having the anode terminals.

In this state, when power is applied to the negative electrode terminal and the positive electrode terminal, hydrogen ions (H ⁺ ), which are positive ions, and chloride ions (Cl ⁻ ), which are negative ions, fly to the gas as the negative electrode.

Accordingly, the hydroxide ions (OH ⁻ ) and sodium ions (Na ⁺ ) remain, and the hydroxide ions (OH ⁻ ) and sodium ions (Na ⁺ ) react to form sodium hydroxide (NaOH).

However, the apparatus for producing caustic soda using the ion exchange membrane method as described above has a problem in that a large amount of power is required in performing the electrolysis as described above.

That is, such electricity is usually produced through fossil fuels, and thus fossil fuels used to produce electricity have a problem of accelerating global warming by emitting carbon dioxide.

In addition, when using electricity produced as fossil fuel as described above there is a problem that the manufacturing cost of caustic soda rises.

Accordingly, the present invention has been made to solve the above-described problems, the object of which is to produce power by itself through power generation means, such as solar power generation unit and hydroelectric power generation unit, using the produced power to produce seawater By separating it into caustic soda and fresh water, it uses green energy that can reduce the enormous cost of caustic soda and fresh water while eliminating carbon dioxide emissions and fossil fuels that cause global warming because there is no external power supply. It is to provide a method and apparatus for separating seawater into caustic soda and fresh water.
