Description
The present invention relates to a method for storing and using sterilizing water in which the content of an oxidizing material containing hypochlorous acid is maintained as it is, and an oxidizing substance such as hypochlorous acid produced by electrolysis is chemically unstable in an acidic or neutral region, The present invention relates to a method for storing and using sterilized water in which an oxidant in the sterilized water can be maintained as it is without being halved for a long time.
As disclosed in Korean Patent Registration No. 10-849657, the inventor of the present application has disclosed a method and apparatus for producing sterile physiological saline having a controlled oxidizing substance content and high sterilizing power, Hypochlorous acid (HOCl), which accounts for most of the residual chlorine, produces sterile water with high sterilizing power.
However, as shown in Fig. 1, the residual chlorine generated during the electrolysis is chemically unstable in the acidic or neutral region, and its content is reduced with a half-life of about 3 minutes. On the other hand, when hypochlorous acid (HOCl) is sucked into the mammal's body, its half-time is significantly reduced to 44 hours. Therefore, once inhaled into the body, it is sufficient to sterilize viruses and bacteria in the body Time can be secured.
Therefore, sterilized physiological saline produced by electrolysis can be used to wash contact lenses immediately after preparation within 3 minutes before the stomach content is halved, to spray in the nose or eyes, to spray on the skin of allergy patients, Spraying around the gum, spraying on the throat, spraying on the hair, spraying on the hair, gagging, spraying in the uterus or vagina, or spraying on the skin with athlete's foot is necessary for high germicidal efficacy.
However, sterilized water containing residual chlorine, such as hypochlorous acid, has a very short half-life in a neutral to weakly acidic environment, and therefore involves a disadvantage in use that must be immediately prepared and used in the field. Accordingly, there is a need to provide a method of maintaining the sterilizing power for a long period of time even if it is not produced in the field.
Disclosure of Invention Technical Problem [8] The present invention has been made to solve the above-mentioned problems, and it is an object of the present invention to provide a sterilizing composition containing hypochlorous acid-containing oxidizing agent, which is produced by electrolysis, for a long time in a weakly acidic or neutral region, To be able to utilize it.
In order to solve the above-described problems, the present invention provides a method of preparing a salt solution, comprising: preparing a solution containing a salt component at pH 4.0 to pH 7.5; A sterilizing water producing step of electrolyzing the solution to produce a sterilized water containing residual chlorine including hypochlorous acid in the solution; A freezing step of freezing the sterilized water to make ice; A transporting and storing step of transporting or storing sterile water in the form of ice by the freezing step; The sterilized water can be stored and used in various ways.
Here, the pH of the solution is maintained at a pH of from about 4.0 to about pH 7.0, which is slightly acidic to neutral, to maximize the production of hypochlorous acid, which is about 80 times higher in sterilization power than OCl-, which is produced when a basic solution is electrolyzed It is for this reason. However, since hypochlorous acid is produced in a slightly acidic or neutral state, it is chemically incomplete in a slightly acidic to neutral state and has a short half-life of 3 minutes. Therefore, in order to utilize hypochlorous acid having a high sterilizing power for various purposes, There was a limit to be manufactured.
However, the present invention is based on a new finding that, when freezing the sterilized water, the sterilizing power of the sterilized water is maintained and maintained for a long time, the sterilized water containing residual chlorine such as hypochlorous acid produced by electrolysis is frozen The advantageous effect that the time for maintaining the sterilizing power can be remarkably prolonged can be obtained.
Here, the refrigeration step may be started while the sterilizing water generating step is being performed and rapidly frozen so that the residual chlorine generated by the electrolysis is frozen together with the sterilizing water, and before its content decreases by a short half- So that the content of the oxidized product or the like produced by electrolysis can be maintained as it is at the time of its production for a long time.
On the other hand, the present invention provides a method for producing a salt, comprising: preparing a solution containing a salt component at pH 4.0 to pH 7.5; A sterilizing water producing step of electrolyzing the solution to produce a sterilized water containing residual chlorine including hypochlorous acid in the solution; A freezing step of freezing the sterilized water to make ice; Supplying the sterilized water in the form of ice generated by the refrigeration step to the livestock as a substitute for water; The sterilized water can be stored and used in various ways.
The present invention also provides a method for producing a salt, comprising: preparing a solution containing a salt component at pH 4.0 to pH 7.5; A sterilizing water producing step of electrolyzing the solution to produce a sterilized water containing residual chlorine including hypochlorous acid in the solution; A freezing step of freezing the sterilized water to make ice; Placing the sterilized water in the form of ice produced by the freezing step on a shelf of fish or meat to maintain freshness; The sterilized water can be stored and used in various ways.
On the other hand, the present invention provides frozen ice in the form of ice as described above. As a result, sterilized water containing residual chlorine such as hypochlorous acid which is harmless to human body can be stored and transported for a long time. In addition, when the sterilizing water is prepared at a physiological saline concentration, the sterilized water in the form of ice may be rubbed into skin wounds and disinfected while suppressing analgesia. In the case of melting and melting in the mouth, .
Since the hypochlorous acid which is maximally produced in a slightly acidic to neutral solution is chemically incomplete and has a short half-life of 3 minutes, there is a limit to utilize hypochlorous acid having a high sterilizing power for various purposes. However, It is possible to obtain a favorable effect that the time for maintaining the sterilizing power can be remarkably extended by freezing the sterilized water containing residual chlorine such as hypochlorous acid produced by electrolysis.
Accordingly, even if there is a difference between the place of production and the place of use, sterilized water containing hypochlorous acid which is harmless to human body and livestock and has a high sterilizing power is stored in freezing as soon as electrolysis is performed. It is possible to obtain an advantageous effect.

FIG. 2 is a flowchart sequentially illustrating a method for storing and using sterilizing water according to an embodiment of the present invention; FIG.
3 is a graph showing measurement data of residual chlorine when the sterilized water is frozen and not frozen according to the present invention.
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail to avoid obscuring the subject matter of the present invention.
The sterilization water storage method (S100) according to the present invention includes a solution preparation step (S110) for preparing a solution having a neutral to weak acidity, a sterilization water generating step (S120) for electrolyzing the solution to generate sterilized water, A step S140 of storing or transporting the sterilized water in the frozen state, a use step S150 of using the sterilized water in the ice state for the intended use, a refrigeration step S130 for rapidly freezing the sterilized water, .
The solution preparing step (S110) prepares a weakly acidic to neutral solution of pH 4.0 to pH 7.5. Prepare brine containing salt or the like in the solution so that residual chlorine can be produced by electrolysis. It is preferable that the solution maintains a slightly acidic or neutral state so that a large amount of harmful hypochlorous acid (HOCl) is generated in the composition ratio of residual chlorine produced by electrolysis, which is 80 times higher than the OC1-.
In the sterilizing water generating step (S120), a DC current is applied in a state in which the electrode is immersed in the solution, so that a large amount of residual chlorine is generated in the solution, and the sterilizing water is sterilized by self-sterilization. The sterilization water generating step (S120) may be performed using the sterilizing water producing apparatus disclosed in Korean Patent Publication No. 10-660941 proposed by the inventor of the present application, and may be manufactured from sterilized water using a general flat electrode. In addition, in the case of producing physiological saline solution or medical sterilization water having sterilizing power, it is also possible to produce sterilized saline solution or medical sterilization water in accordance with the method disclosed in Korean Patent Registration Nos. 10-651122, 10-849657, 10-789325, and 10-849618 Method. ≪ / RTI >
That is, the sterilizing water according to the present invention includes all of sterilization water for various purposes such as providing to livestock, storing general fish, meat, etc., washing contact lenses, medical use for human body, or physiological saline .
When the sterilized water containing a large amount of hypochlorous acid (HOC1) is produced in the sterilizing water producing step (S120) by electrolysis, the refrigeration step (S130) rapidly freezes sterilized water. This is because it is preferable that the sterilized water is frozen simultaneously with the production of the sterilized water since the half-life thereof is very short.
According to another embodiment of the present invention, while the residual chlorine containing hypochlorous acid is produced by supplying the DC power to the electrode immersed in the solution, the freezing is gradually started so that the sterilizing water can be solidified as soon as possible to become ice have. According to another embodiment of the present invention, a container containing a solution produced by sterilizing water is formed in a shape having a large surface area (narrow shape) as much as possible so as to maximize the surface exposed to cold air, Allow to cool.
Thus, when the sterilized water is immediately frozen, the half-life of the residual chlorine including hypochlorous acid is prolonged so that the residual chlorine does not disappear and the concentration at the time when it is produced by electrolysis can be maintained for a long time. That is, as shown in FIG. 3, a protruding electrode disclosed in Korean Patent Publication No. 10-660941 was immersed in a solution having a salt concentration of 1% and a pH of 5.0, and a current of about 180 mA was applied to obtain a concentration of 6 ppm , There is a large difference in the concentration of residual chlorine over time when the sterilized water prepared in accordance with the present invention is immediately frozen or placed at room temperature (20 ° C).
In other words, when the sterilized water producing the residual chlorine by electrolysis of the solution is instantly frozen (this point is indicated as 0 minutes in Fig. 3), the residual chlorine of 5% or less Although there was a decrease in the concentration, at room temperature, when the elapse of about 100 minutes, a concentration of residual chlorine of 70% or more occurred. 3, the decrease of the residual chlorine concentration is shown in the following Table 1 when it is left for about 3 days.
[Table 1]
As shown in Table 1, in the frozen state, the reduction range of residual chlorine is 0.1 ppm to 1.6 ppm even after three days have elapsed, and the decrease range of residual chlorine is from 3.0 ppm to 5.8 It was confirmed that the decrease was in the range of 65% to 80% as ppm. (For reference, the half-life of hypochlorous acid is known to be 3 minutes. Therefore, the decrease in residual chlorine at room temperature should be larger than that shown in the table above. However, residual chlorine other than hypochlorous acid reacts with components in the solution, However, in the case of room temperature, the decrease in concentration of residual chlorine, which has sterilizing power, is much greater than that in the frozen state.
It has been experimentally confirmed that the concentration of residual chlorine including hypochlorous acid having a high sterilizing power can be maintained for a long time for a long time by instantly freezing the sterilized water containing residual chlorine produced by electrolysis.
Therefore, the sterilized water generated in the sterilization water producing step S120 can be stored and transported in ice form for a long time by the refrigeration step S130 (S140). Therefore, even if sterilized water is not produced directly at the site of use, sterilized water can be produced by electrolysis at a factory or the like, and then transported to a place where it is to be used while maintaining a frozen state.
The utilization step (S150) may be utilized in various forms that utilize sterile water. For example, since sterilized ice transported in an ice state still contains a large amount of residual chlorine such as hypochlorous acid harmless to the human body, when sterilized water is produced at a physiological saline concentration, it may be used for cleaning a contact lens , And it can be used for preventing and treating periodontitis by sterilizing the mouth by slowly dissolving it in the mouth. In addition, the sterilized ice can be used for disinfecting while suppressing the pain of rubbing against skin wounds.
In addition to being used in the human body, it can also be used to prevent infectious diseases by disinfecting the mouth and nose area by supplying water to livestock such as cattle, pigs, and chickens. In addition, it is also possible to use sterilized ice on fish or meat to sell fish and meat, and sell fish and meat for sale. Fish and meat can be kept clean and sanitized for a long time.
As described above, the present invention is advantageous in that the sterilized water containing residual chlorine, which has been conventionally produced in the field, can be stored for a long time and used for various purposes in the right place.
While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
