Description
The present invention relates to a strong acidic electrolyzed water generating device for aquaculture for recycling hydrogen gas generated from strong alkaline electrolyzed water of an electrolytic cell.
In particular, an electrolyte solution (5) made of seawater or brine is introduced into an electrolytic cell (4) having a positive electrode (1), a negative electrode (2), and a diaphragm (3) to form a strong acidic electrolyzed water (6) and a strong alkaline electrolyzed water (7). In the producing apparatus, the hydrogen gas (H2) generated in the strong alkaline electrolyzed water (7) inside the strong alkaline electrolyzed water storage tank (8) is transferred to the bottom of the strong acid electrolytic water storage tank (10) by the conduit (9), and the ejector ( 11) by spraying the strong acid electrolyzed water (6) through the hydrogen gas to react with the chlorine gas and oxygen of the strong acid electrolyzed water, reducing the risk of explosion of hydrogen gas and the concentration of hypochlorous acid (HOCl) and hydrochloric acid (HCl) in the strong acid electrolyzed water. The present invention relates to a strong acidic electrolyzed water generator for aquaculture, characterized in that to produce a strong acidic electrolyzed water with a greatly improved acidity.
Conventional seaweed farms have been added to the seaweed by adding mineral acids such as hydrochloric acid and sulfuric acid to Gimbal to control seaweed and seaweed germs. In order to compensate for this, the government recommends spraying organic powders in aquaculture farms, but fishermen are refusing to use them because they are more expensive, weaker and more persistent than inorganic powders.
Recently, the government announced that organic acid containing less than 9.5% of inorganic acid is to be used in aquaculture farms, and it is distributed to fishermen as government support, but this acid treatment agent is also known to be weak and polluting the ocean.
On the other hand, a device using electrolysis of seawater and electrolyzed water as an acid treatment agent for seaweed has already been researched and developed (Patent Registration No. 10-0366899). Mounting was structurally difficult to operate. Therefore, if the electrolytic water generator is installed indoors in a factory or the like to produce electrolyzed water with seawater, hydrogen gas generated from the strong alkaline electrolyzed water is spewed into the room, accumulated in the ceiling, and fired by the electric short circuit or carelessness. There was a risk of large explosions and fires.
Therefore, in the electrolytic water generating device, it is safe to transport the hydrogen gas to the pipeline and discharge the gas well to the outside atmosphere.However, the hydrogen gas discharged to the air is a valuable resource that can be discarded. Development is urgently needed.
The present invention has been directed to solve the problems described above, and relates to a strong acid electrolytic water generating device for aquaculture for recycling hydrogen gas generated in the strong alkaline electrolyzed water of the electrolytic cell. In particular, an electrolyte solution (5) made of seawater or brine is introduced into an electrolytic cell (4) having a positive electrode (1), a negative electrode (2), and a diaphragm (3) to form a strong acidic electrolyzed water (6) and a strong alkaline electrolyzed water (7). In the generating device, the hydrogen gas (H2) generated in the strong alkaline electrolytic water storage tank (8) is transferred to the bottom of the strong acid electrolytic water storage tank (10) by the conduit (9), and the strong acid electrolytic water through the ejector (11). (6) to make the hydrogen gas react with chlorine gas and oxygen in strong acidic electrolyzed water, reducing the risk of explosion of hydrogen gas and increasing the concentration of hypochlorous acid (HOCl) and hydrochloric acid (HCl) in strong acidic electrolyzed water It is to produce enhanced acidic electrolyzed water.
When explaining the solution of the problem of the present invention based on the accompanying drawings as follows.
A strong acid electrolyzed water (6) and a strong alkaline electrolyzed water (7) are produced by introducing an electrolyte solution (5) made of seawater or brine into an electrolytic cell (4) having a positive electrode (1), a negative electrode (2), and a diaphragm (3). In the apparatus, the hydrogen gas (H2) generated in the strong alkaline electrolytic water storage tank (8) is transferred to the bottom of the strong acid electrolytic water storage tank (10) by the conduit (9), and the strong acid electrolytic water (6) through the ejector (11). It is intended to be sprayed on).
Conventionally, hydrogen gas (H2) generated in the strong alkaline electrolytic water tank (8) of the seawater electrolysis device has been mostly organic in the air,
The present invention transfers the hydrogen gas (H2) generated in the strong alkaline electrolytic water tank (8) to the strong acid electrolytic water storage tank (10) to chemically combine with chlorine gas and oxygen to effectively recycle the hydrogen gas to reduce the risk of explosion and strong acid electrolytic water Has the advantage of increasing acidity and producing strong acidic electrolyzed water by increasing the concentration of hypochlorous acid and hydrochloric acid.
Example 1
As shown in FIGS. 1 and 2, an electrolytic solution 5 made of seawater or brine (NaCl solution) is electrolyzed in an electrolytic cell 4 equipped with a positive electrode 1, a
Chlorine gas generated at the anode side is reacted with water (hydrolysis) to give the following reaction formula.
NaCl → Na + + Cl-
2Cl → Cl 2 + 2e
Cl 2 + H 2 O → H + + Cl - + HOCl
The strong acidic electrolyzed water (6) generated at the anode (+) contains a large amount of hypochlorous acid (HOCl), which has a strong oxidation effect, and becomes a strong acidic water having excellent oxidation power with a potential of more than + 1100mv of redox potential. In addition, the strongly acidic electrolyzed water 6 is a liquid of pH 2.7 or less in which microorganisms do not survive, and has stronger antibacterial and bactericidal action than hydrochloric acid (HCl) at the same pH. Therefore, the strongly acidic electrolyzed water (6) is very suitable to be used as an acid treatment agent to control the laver and seaweed germs of seaweed.
When the strong acidic electrolyzed water 6 comes into contact with air, light or organic matter, a reversible reaction (reaction proceeds from right to left) corresponding to the above equation occurs, and chlorine gas (Cl 2 ) and water (H 2 O) are used. It is an eco-friendly seaweed acid treatment agent (seaweed active treatment agent) that can be used with confidence because it has no residual property because it returns.
On the other hand, the electrolytic solution 5 made of seawater or brine (NaCl solution) is electrolyzed in an electrolytic cell 4 equipped with a positive electrode 1, a
NaCl → Na + + Cl-
Na + + el → Na
Na + H 2 O → NaOH + 1 / 2H 2
That is, negative (-), the electrolytic water contains hydroxyl ions (OH -) generated from more becomes a strongly alkaline electrolyzed water (7)
And sea water or brine (NaCl)
2H + + 2e- → H2
2H2O + 2e- → 2OH- + H2
4OH- → O2 (g) + 2 H2O + 4e-
Putting these three equations together, water is electrolyzed with hydrogen and oxygen as shown in the following equation.
2H2O → 2H2 + O2
In other words, if there is a diaphragm between the positive electrodes, the movement of ions is restricted, and OH- is oxidized (soaks up electrons) on the anode side to generate
Therefore, the hydrogen gas (H2) generated on the negative electrode (2) side is transferred from the negative electrode (2) of the electrolytic cell (4) to the strong alkaline water storage tank (8) through the negative electrode side electrolytic water transport pipe (14) as shown in FIG. This hydrogen gas (H2) continues to increase the atmospheric pressure inside the storage tank. The increasing hydrogen gas (H2) is a risk of explosion, so must be safely discharged, the present invention transfers the hydrogen gas (H2) to the strong acidic electrolytic water storage tank (10) by the pipeline (9) 11), the hydrogen gas (H2) reacts with chlorine gas (Cl2) and oxygen (O2) generated in the strongly acidic electrolyzed water (6) and hypochlorous acid (HOCl) and Allow hydrochloric acid (HCl) to be produced.
H2 (g) + O2 (g) + Cl2 (g) → 2HOCl (g)
H2 (g) + Cl2 (g) → 2HCl (g)
Thus, if hypochlorous acid (HOCl) and hydrochloric acid (HCl) continue to be generated in the strong acidic electrolyzed water storage tank (10), the chlorine ion concentration of the strong acidic electrolyzed water (6) can be increased and the pH can be further lowered. (6) has a strong acidity can be used as an eco-friendly seaweed acid treatment agent with a strong effect of controlling blemishes and bottled water, the amount of hydrogen gas (H2) discharged to the gas outlet (12) is also significantly reduced electrolyzed water It can reduce the risk of hydrogen gas explosion which can occur frequently in the production process.
