The present invention relates to a disinfectant water production apparatus for producing iodine disinfectant water having a continuous sterilizing power, the disinfectant water prepared by the present invention is prepared to instant sterilization of various bacteria.

Conventionally, iodine was dissolved in ethyl alcohol or a carrier in a 2% solution, and diluted to about 25 ppm when used as a disinfectant for left bath or hand washing. There was a hassle to prepare and use disinfectant water by diluting each time.

The present invention relates to a disinfectant disinfectant water production apparatus having a function of instantaneously disinfecting a part or object of the body contaminated with bacteria, which is convenient to use without electrical auxiliary facilities, and can be sterilized completely by instant contact. In addition, the long life is to provide a disinfectant manufacturing apparatus that can be used in the long term.

The present invention is to provide a device for producing iodine disinfectant water by binding a high concentration of iodine to a carrier such as an anion exchange resin and then filling it in a plastic case to gradually elute iodine to a constant concentration over a long period of time.

In addition, the present inventors have found that the change in the amount of elution and the lifespan are determined according to the method of high concentration of iodine binding and the type of carrier.

Another object of the present invention is to manufacture for the purpose of using the content of iodine of the disinfectant water passed through the disinfectant water production apparatus of the present invention, it can be used for the production of disinfectant water, such as various medical devices for disinfection, vegetables, fruits and dishwashers and bidet To provide a disinfectant water production apparatus that can be.

The present invention relates to a disinfectant water production apparatus for producing iodine disinfectant water having a continuous sterilizing power. The iodine disinfecting water production apparatus of the present invention was invented to remove the hassle that the conventional disinfecting water was diluted to an appropriate concentration when using iodine prepared in about 2% stock solution of iodine in ethyl alcohol or a carrier. By just sending, it has the function of preparing disinfectant water so that the iodine becomes about 2-50 ppm according to the use, and has the function of instant sterilization of various bacteria.

Iodine is inherently very soluble in water, but mixing iodine and iodine ions in an appropriate molar ratio produces ionic iodine compounds in a small amount of water, which is very soluble in water. When activated carbon, anion exchange resin, or a mixture thereof is added thereto as a carrier, a high concentration of iodine compound is ion-bonded or adsorbed to the carrier to serve as a reservoir of iodine (hereinafter, iodine-carrier). Iodine has a wide range of binding force from strongly ionically bonded to the carrier to relatively weakly adsorbed iodine, thereby continuously dissolving iodine in water passing through the iodine-carrier.

The apparatus for preparing disinfecting water of the present invention fills a plastic case with an iodine-carrier conjugate, which is an iodine compound bonded to a carrier, seals both ends with a filter cloth, and then closes the cap with a tube to prepare a high concentration iodine-carrier filter. When water passes through the iodine-carrier, the iodine is continuously eluted to produce a disinfecting water production apparatus for producing disinfecting water having a sterilizing effect.

As described above, as the carrier in which the iodine compound is bonded in the present invention, activated carbon, anion exchange resin, or a mixture thereof may be used. When using activated carbon as a carrier, iodine may be sublimed in a sealed container to be activated carbon. A method of adsorbing or a method of dissolving iodine in alcohol and adsorbing on activated carbon may also be used.

In addition, when preparing the iodine-carrier, it is also possible to produce by iodine concentrated in alcohol or more than solubility, or by heating and subliming iodine to adsorb.

Disinfectant water production apparatus of the present invention is further provided with a valve-type flow rate control means for adjusting the amount of water passing through the iodine-carrier, it is possible to adjust the iodine concentration of the disinfectant water eluted.

Hereinafter, the present invention will be described in more detail.

Method for making a high concentration of iodine-carrier conjugate in the present invention is as follows.

First, iodine and iodine flame is mixed to dissolve iodine in a minimum amount of water in a high concentration, and is bound to an anion exchange resin. In the present invention, 1 to 4 mol of iodine and 1 mol of iodide are mixed, and more preferably, 2 to 3 mol of iodine and 1 mol of iodide are mixed and dissolved in a minimum amount of water to form an ionized iodine compound (for example, I _{3 ^{-, I 5 -, I 7}} -) is generated which is more than 100 times higher than that of the solubility of iodine in water. Wherein the iodine compound concentration in the produced high density anion exchange resin (Amberite series, Dowex series, Diaion series) high concentration adsorbed in a variety of bonding when immersed approximately one day in (AS) iodine-carrier conjugate (I ₇ ^- - ⁺ AS , I ₅ ^- is manufactured ^{+ AS) - - + AS,} I 3 -.

Second, iodine is dissolved in a minimum amount of alcohol (ethanol or methanol) and adsorbed onto activated carbon (S) (powder activated or granular activated carbon with iodine adsorption capacity of 1000 or more) or anion exchange resin (AS) (Amberite series, Dowex series, Diaion series) It is a method of manufacturing. In this case, it is more preferable to adsorb the activated carbon. When iodine is saturated with ethanol and excess iodine is left, the mixture is stirred with activated carbon or anion exchange resin, and the dissolved iodine is adsorbed on the carrier, and at the same time, iodine dissolution proceeds, resulting in high concentration of iodine-carrier conjugate (I _2- ⁺ AS Or I ₂ -S) is prepared. At the same time, dissolution and adsorption to the carrier have a higher concentration of adsorption capacity than 10 times.

Third, when the iodine and the carrier are put in a closed glass container and heated, the sublimed iodine is adsorbed to the carrier at a high concentration. At this time, activated carbon (powder activated carbon or granular activated carbon with iodine adsorption force of 1000 or more) (S) or anion exchange resin (Amberite series, Dowex series, Diaion series) (AS) can be used, and in this case, more preferably, It is a method of adsorbing. Heating the iodine to sublimate to bind to the carrier to produce a high concentration of iodine-carrier conjugate (I _2- ⁺ AS or I ₂ -S). In the present invention, 100 g or more of iodine could be adsorbed onto 100 g of carrier.

The iodine-carrier conjugate prepared as described above has various binding strengths, since the high concentration of iodine compound is bound by various adsorption mechanisms depending on the exposure degree of activated carbon and anion surface. The physical adsorption mechanism by van der Waals attraction between iodine and the carrier is due to the combination of I _2- ⁺ AS or I ₂ -S, which is due to the weak attraction between iodine-carrier and adsorbed iodine in a short time. It is eluted. The anion-if it is relatively strongly chemically adsorbed by the anion Coulomb force is ^{_{I 7 - - + AS, I}} 5 - - + AS, I 3 - - the time it takes the chemical structure was eluted in ⁺ AS becomes long. In other words, proper coordination of iodine with strong binding force with iodine at the time of weak binding force with the carrier allows the elution of iodine to be sustained in the long term.

Was observed to increase in the order of ^{+ AS - - + AS> I} 5 - - - + AS> I 3 - concentration of iodine is eluted when I ₇ was used with the same type of carrier (AS). This is because elution becomes easier as I ₂ becomes farther from the carrier AS. As an example I ₇ ^- is [IIIIIIIS] ^- the chemical structure it has the end of the I ₂ -I ₂ - is so much away from the carrier and the distance S is the elution of I ₂ by being the bonding force weakens more. However, the manufacturing hagieneun _{^{I 7 - - + AS <I}} 5 - - + AS <I 3 - - + because it is easy in the order of AS can control the elution of iodine as an appropriate ratio.

The amount of iodine elution depends on the weight of the iodine-carrier used. In other words, the higher the amount of iodine-carrier, the higher the amount of iodine elution.

Referring to the disinfection water production apparatus of the present invention in more detail with reference to the drawings, Figure 1 shows an iodine-carrier filter 30 is provided with a flow control means 5 is an example of the disinfection water production apparatus 50 of the present invention Figure 2 is a cross-sectional view, Figure 2 is a view showing the disinfecting water production apparatus 50 of the present invention showing further comprising a pre-filtration means 20 and the disinfection water storage tank 40.

In the present invention, the disinfectant water production apparatus 50 is filled in the interior of the disinfection and water purifier case (2) through which the high concentration iodine-carrier (1) is penetrated, the coupling cap (4) inside the both sides By installing a filter cloth (3) made of a non-woven fabric or mesh, a high concentration iodine-carrier filter 30 is prepared and used so that the packing material does not escape. The size of the case is generally used in the diameter of 1 ~ 3cm, length 3 ~ 20cm, the concentration of the iodine disinfectant is produced according to the amount of filling the high concentration iodine-carrier (1) amount according to the user desired concentration Can be optionally adjusted.

Disinfectant water production apparatus 50 of the present invention is sealed by the cap (4) equipped with a tube after sealing by using the filter cloth (3) and further provided with a flow rate adjusting means (5) of the valve type in the inlet portion It is also within the scope of the present invention to control the content of iodine eluted by controlling the flow rate of water passing through the iodine-carrier (1).

In addition, in order to supply water to the iodine-carrier filter 30 is installed in multiple stages to remove various foreign substances, heavy metals, ions contained in the water supply source 10 and the water supplied from the water supply source 10 and carbon It further includes the pre-filtration means 20 is formed by connecting at least one filter or reverse osmosis filter flows the filtered water to the iodine-carrier filter 30 through the water supply pipe 6, the iodine-carrier ( It is also within the scope of the present invention to further include a storage tank 40 for storing sterile water from which iodine produced through 1) is eluted.

In the present invention, it is also possible to control the concentration of iodine by adjusting the temperature of the passing water in the disinfection water production apparatus, and to control the concentration of the iodine disinfection water produced by adjusting the temperature of the passing water in the disinfection water production apparatus range. to be.

In the present invention, it is also possible to control the concentration of iodine by adjusting the flow rate by adopting the flow rate adjusting means in the disinfectant manufacturing apparatus, to control the concentration of the iodine disinfectant produced by adjusting the amount of iodine-carrier in the disinfectant manufacturing apparatus It is also possible.

When the water flow rate is reduced, iodine disinfectant water with a high iodine content is produced. When the water flow rate is high, disinfectant water with a low iodine content is produced. In case the production amount is not enough, it takes a long time, so it is not efficient.

In the case of using iodine-carriers prepared using 1 to 4 moles, more preferably 2 to 3 moles, which is the use range of the iodine of the present invention, the content of iodine eluted according to the amount and the flow rate of water filled in the disinfectant water production apparatus Although it can be controlled, it is most preferable because it can economically prepare iodine disinfectant water having a concentration in the range of 2 to 50 ppm, which is the concentration of iodine generally used. However, the concentration of iodine in the present invention is not limited to the above range, it will be apparent that the user can be adjusted according to the degree desired.

It was.

Experimental Example 1

In the experiment below, a disinfection water production apparatus was manufactured in the same manner as in Example 1, and the elution amount of iodine was measured by changing the temperature of the water passed through 20, 30, 40, and 50 ° C.

As a result, as shown in [Table 1], it can be seen that the amount of iodine elution increases significantly as the temperature increases. It was 2.5 to 3.5 ppm overall at 20 ° C but increased to 13.8 to 15.6 ppm at 50 ° C. Therefore, it can be seen that by adjusting the temperature of the passage water to increase the elution amount of iodine in the disinfection water.

TABLE 1

Experimental Example 2

The iodine elution amount of the sterilized water production apparatus filled with the iodine anion resin prepared in Examples 1 to 5 was measured and presented in [Table 2]. In addition, the sterilization power was prepared in the disinfectant water prepared by the disinfectant manufacturing apparatus prepared in the above Example and the concentration of about 1000 CFU after esherichia coli, Salmonella Typhimurium, Legionella was shown in [Table 3].

TABLE 2

TABLE 3

The iodine elution amount of Example 1 was 2.5 to 3.5 ppm as a whole. That is, when the iodine-carrier 25 g prepared with a molar ratio of iodine and an iodine salt of 2.5: 1 was used, the elution amount of iodine was maintained at 2.5 to 3.5 ppm and showed more than 95% bactericidal power in three bacteria as shown in Table 3. It maintained sterilization power of more than 95% even after 10,000 liters of water. The iodine-carrier, which can maintain 2.5 to 3.5 ppm of iodine elution, is preferably used as a disinfectant maker in a bidet.

When the molar ratio of iodine (I ₂ ) and iodine flame of Example 2 is 2.5: 1 and 100 g of iodine-carrier is used, that is, the amount of iodine elution when the amount of the iodine-carrier used in Example 1 is increased four times Showed 13.5 ~ 15.4 ppm overall. In this case, as shown in Table 3, the bactericidal power was more than 99% of the three bacteria. It maintained sterilization power of more than 98% even after 10,000 liters of water. If more sterilization is required, increasing the amount of iodine-carrier to increase the amount of iodine elution and sterilization, in this case, it is preferable to use as fruit, vegetables and oral disinfectant.

In Example 3, when the molar ratio of iodine (I ₂ ) to the iodine flame was 4: 1 and 25 g of iodine-carrier was used, the iodine elution amount was 19.5-24.8 ppm as a whole. In this case, as shown in Table 3, the bactericidal power was more than 99.9% of the three bacteria initially. It maintained the same sterilizing power after 10,000 L of water. If the sterilization power needs to be increased, increasing the molar ratio of iodine (I ₂ ) and iodine flame dramatically increases iodine elution and sterilization power. This iodine-carrier is preferably used as instant disinfectant for cookware as well as fruits, vegetables and oral disinfectants. .

Examples 4 and 5 are methods for concentrating iodine (I ₂ ) directly on a carrier, in which dissolution and vapor are iodine elution amounts of 0.3 to 34.2 ppm in total. In this case, the initial iodine elution is relatively high, but as the amount of use increases, the iodine elution rapidly decreases, making it difficult to use in the long term. The sterilization power is also maintained at 94% or more initially, but sterilization power is drastically reduced as the usage increases. These iodine-carriers can be used to supplement the initial iodine elution.

In particular, the device prepared according to Example 1 has a low iodine elution amount but is less irritant, and thus it is advantageous to use it for disinfection of the air and skin. The device manufactured according to Example 3 has an iodine elution amount eluted in general iodine disinfectant water at a final use concentration (25 ppm of iodine) and has excellent sterilizing power, and is suitable for oral disinfection of fruits, vegetables, dishware and dental. In addition, by increasing the amount of iodine-carrier or increasing the temperature, the elution amount of iodine can be increased and sterilization power can be increased. Examples 4 and 5 may be used to increase the amount of initial iodine elution, but are generally not preferred.

The disinfecting water manufacturing apparatus manufactured by the manufacturing method of the present invention can continuously prepare a predetermined concentration of iodine disinfecting water can provide disinfecting water with perfect disinfecting power.

In addition, there is an effect that can provide a disinfecting water production apparatus that can be used for a long time, easy to use, long life without electrical auxiliary facilities.

In addition, the disinfecting water production apparatus according to the present invention continuously produces iodine disinfecting water for more than six months, the device has an effect that can be used for the production of disinfecting water, such as medical equipment, vegetables, fruits and dishwasher, bidet.
