It should be interpreted as a meaning and concept consistent with the technical idea of the present invention on the basis of the principle that it can be defined. Therefore, the configuration of the embodiments described in the present specification is only one preferred example of the present invention, and does not represent all of the technical spirit of the present invention, and various equivalents and modifications that can replace them at the time of application It should be understood that there may be.

The present invention relates to a method of reducing the concentration of carbon dioxide in the atmosphere by using sea water, and more specifically, the advantage of being able to reduce the concentration of carbon dioxide in the atmosphere in an eco-friendly method and at the same time neutralize acidified sea water. It relates to a method of reducing the concentration of carbon dioxide in the atmosphere having.

The method of reducing the carbon dioxide concentration in the atmosphere by using seawater according to the present invention does not depend on a biological method but is an eco-friendly method by using seawater to rapidly reduce the carbon dioxide concentration in the atmosphere in large quantities, thereby reducing global warming and air pollution. It has the advantage of being able to dramatically prevent.

A method of reducing the concentration of carbon dioxide in the atmosphere using sea water according to the present invention will be described in detail with reference to FIG. 1.

The method of reducing the concentration of carbon dioxide in the atmosphere by using seawater according to an embodiment of the present invention is to control the concentration of sodium chloride in the seawater stored in the storage tank (S300), after the concentration control step (S300). An air reaction step (S400) of generating sodium hydrogen carbonate by supplying air in the atmosphere to react, and a reactant separation step (S500) of separating sodium hydrogen carbonate generated in the air reaction step (S400).

In addition, the method of reducing the concentration of carbon dioxide in the atmosphere using seawater according to an embodiment of the present invention may further include a seawater supply step S100 of receiving seawater from the sea and supplying it into the storage tank.

In addition, the method of reducing the concentration of carbon dioxide in the atmosphere using seawater according to an embodiment of the present invention may further include a filtering step (S200) of removing impurities in seawater stored in the storage tank.

In the filtering step (S200), while receiving seawater from the sea and supplying it into the storage tank, impurities in the seawater may be removed through the filtering filter unit.

The seawater supply step (S100) may be performed by installing a storage tank for storing seawater near the beach, and supplying the seawater received through a receiving facility for receiving seawater from the sea to the storage tank.

Depending on the size of the storage tank installed in this way, the scale at which the concentration of carbon dioxide in the atmosphere can be reduced can be determined.

On the other hand, the filtration step (S200) is a step of removing various garbage or marine organisms that may be contained in seawater, and at this time, various mineral components such as sodium chloride contained in the seawater are not removed.

In this way, the filtration step (S200) removes other suspended substances and marine animals and plants other than various minerals contained in seawater, thereby increasing the reaction efficiency between air containing carbon dioxide in the atmosphere and seawater, which will be described later. And, it is possible to extend the service life of the storage tank.

Meanwhile, the concentration control step S300 is performed to increase the reaction efficiency between sodium chloride contained in seawater and carbon dioxide contained in air in the atmosphere.

The concentration control step (S300) is carried out through a process of increasing the salinity of seawater by adding salt to the storage tank, or after the air reaction step (S400) is terminated and the seawater that has passed through the reactant separation step (S500) is heated. It may be carried out by supplying it into a storage tank.

In the concentration control step (S300), when the concentration of sodium chloride contained in the seawater is adjusted by heating the seawater after the reaction has been completed to increase the concentration of residual sodium chloride and supplying it to the storage tank again, it is directly collected from the sea (SW). It has the advantage of being able to omit the process of filtering sea water and also reducing the cost required for separate water intake.

The reaction in which sodium hydrogen carbonate is generated in the air reaction step (S400) is performed by a reaction through Formula 1 below.

[Formula 1]

NaCl + H ₂ 0 + C0 ₂ --> NaHCO ₃ + HCl

Through the reaction of Formula 1, carbon dioxide (C0 ₂ ) contained in the atmosphere reacts with sodium chloride (NaCl) contained in seawater with water to generate sodium hydrogen carbonate (NaHCO ₃ ), and in this process, hydrochloric acid gas (HCl) Is discharged.

The air reaction step S400 may include a process of generating sodium hydrogen carbonate by reacting seawater and air containing carbon dioxide, and a process of discharging the reacted air back into the atmosphere.

Through this process, the concentration of carbon dioxide contained in the atmosphere can be continuously reduced.

In the process of discharging the reacted air back into the atmosphere, after passing through the air reaction step (S400), seawater containing air is circulated from the bottom of the storage tank to the top and discharged to the outside atmosphere.

Sodium hydrogen carbonate (NaHC0 ₃ ) produced through Formula 1 is called baking soda, and it is widely used in confectionery or cleaning.

Thus, reaction separation step (S500) is to separate the (NaHCO ₃₎ of sodium bicarbonate produced in the reaction phase air (S400) and to work in a variety of fields that can be used are bicarbonate (NaHCO ₃₎ acid.

In the method of reducing the carbon dioxide concentration in the atmosphere by using seawater according to another embodiment of the present invention, the concentration control step (S300) uses the seawater from which the reactant separation step (S500), that is, the seawater from which sodium bicarbonate is separated. Can be done by

That is, the seawater in which sodium hydrogen carbonate (NaHCO ₃ ) is produced through Formula 1 has a lower concentration of sodium chloride, but sodium chloride is not completely depleted. Accordingly, the seawater used in the reaction of Formula 1 is Sodium chloride concentration can be increased.

Typically, a maximum of about 35 g of sodium chloride can be dissolved in 100 g of water under the condition of 1 atmosphere at 25°C, and about 3.1 to 3.8% by mass of sodium chloride is dissolved in seawater.

At this time, for example, in the concentration control step (S300), the seawater from which sodium bicarbonate is separated in the reaction product separation step (S500) is heated in a separate auxiliary tank 1100, and then the heated seawater is filtered (S200). It may be carried out through a process of additionally supplying the stored seawater through the filtering step (S200) in the storage tank.

Meanwhile, the air reaction step (S400) may further include a process of collecting and removing gas discharged while the reaction is in progress in the reaction process.

That is, as can be seen from Formula 1, hydrochloric acid gas (HCl) is discharged in the process of reducing the carbon dioxide concentration in the atmosphere through the process according to the present invention.

In the air reaction step (S400), hydrochloric acid gas (HCl) is generated, and the generated hydrochloric acid gas (HCl) may be returned to the atmosphere, or may be used for various heating through the process of Formula 2 below.

[Formula 2]

Zn + HCl ~> ZnCl ₂ + H ₂ + Thermal energy

That is, as shown in Formula 2, when the hydrochloric acid gas generated in the air reaction step (S400) is reacted with zinc, zinc chloride (ZnCl ₂ ) and hydrogen gas are generated, and a large amount of thermal energy is generated in this process.

As described above, the thermal energy generated through the reaction of Formula 2 can be used for household, agricultural, or industrial heating.

Meanwhile, the method of reducing the concentration of carbon dioxide in the atmosphere using seawater according to another embodiment of the present invention further includes a reactant treatment step (S600) of introducing sodium hydrogen carbonate separated in the reactant separation step (S500) into the sea. can do.

That is, in the reactant treatment step (S600), sodium hydrogen carbonate is introduced into the sea (SW), thereby obtaining an effect of neutralizing the acidified sea water as sodium hydrogen carbonate is decomposed.

Meanwhile, in the air reaction step (S400), the seawater in which the reaction proceeds is discharged to the sea (SW), and the new seawater is supplied into the storage tank, while the seawater and the air containing carbon dioxide are reacted to generate sodium hydrogen carbonate. can do.

In other words, since the concentration of sodium chloride contained in the seawater supplied in the process of carrying out the carbon dioxide reduction method of the present invention decreases, new seawater in which about 3.1 to 3.8% by mass of sodium chloride is dissolved is continuously supplied to the storage tank. You need a process.

Meanwhile, the air reaction step (S400) may further include a process of adding dry ice.

That is, in the process of performing the reaction of seawater and air containing carbon dioxide in the air reaction step (S400), when dry ice is added, the reaction for formation of sodium bicarbonate can be remarkably accelerated, and carbonation by dry ice It is also possible to accelerate the initiation of the reaction for producing sodium hydrogen.

In addition, when dry ice is added, the temperature of seawater reacting with the air in the atmosphere is lowered, so that the amount of generation of hydrochloric acid gas (HCl), which is a harmful gas, is drastically reduced.

On the other hand, the reaction product separation step (S500) may include a process of allowing sodium hydrogen carbonate to collect in a sieve provided under the storage tank, and drying the sodium hydrogen carbonate by separating the sieve in which sodium hydrogen carbonate is collected from the storage tank.

In the storage tank, a strainer for collecting sodium hydrogen carbonate can be installed detachably, and the strainer is separated from the storage tank so that all moisture from the outside of the storage tank flows down the strainer, and the remaining sodium hydrogencarbonate is filtered off the top of the strainer. It can be carried out in a process of drying.

That is, the strainer may be made of a material such as metal or plastic, and the strainer thus produced may be variously implemented using a known strainer having a plurality of fine-diameter pores in the lower part. It should be noted that it is omitted.

The size of the hole formed as described above may be formed to have a diameter such that the fine lumps of sodium hydrogen carbonate generated by solidification cannot pass, but only moisture.

After a certain period of reaction, when enough sodium hydrogen carbonate is produced in the sieve, the sieve is taken out from the storage tank and placed in a holder for mounting the sieve, and moisture other than sodium bicarbonate passes through a number of through holes formed in the sieve. To be discharged to the bottom by

When the sodium hydrogen carbonate from which moisture has been sufficiently removed is naturally dried or hot air dried on a strainer, sodium hydrogen carbonate becomes very hard, and the completely hardened sodium hydrogen carbonate is used separately or stored in the sea (SW). It is possible to process.

In the reactant separation step (S500), sodium hydrogen carbonate may be separated in the process of circulating the reacted seawater from the bottom of the storage tank to the top, or sodium hydrogencarbonate may be separated in the process of discharging the reacted seawater into the sea (SW). May be.

That is, the strainer may be detachably located in a circulation pipe that circulates the reacted seawater from the bottom of the storage tank to the top, or may be detachably located in the discharge pipe portion that discharges the reacted seawater to the sea (SW).
