Amid the growing awareness of the importance of hand washing due to the spread of coronavirus infection-19, the history of disinfection has emerged as a new issue.

The history of disinfection began when the Egyptians used preservatives on corpses. Ancient Egyptians used preservatives on corpses, which can be seen as an example of disinfection and sterilization, and Hippocrates, the father of medicine, used boiled water to clean wounds and washed hands. Was important.

In addition, it is emphasized that the operator's hands and nails should be cleaned, and there is a known case of dressing with various drugs on wounds.In particular, in the Middle Ages, disinfection technology did not develop much due to the dark period. As the founder of the pasteurization method, he established the basis for aseptic surgery.

In the past, it is known that many people died of sepsis after amputation, and it was discovered that deaths occurred due to not disinfection, and the importance of disinfection spread, and in 1847 Gemmelweiss of Austria implemented the'handwashing policy'. After that, sterilization using chemical substances was also developed.

In enclosed indoor spaces such as rooms, offices, living rooms, PC rooms, coffee shops, toilets, etc., pollutant gases from outside environments such as heating devices, humidifiers, office equipment, asbestos, dust, cement, cigarette smoke, etc. Biohazard factors such as bacteria, germs, fungi, and viruses are present together. These factors contaminate indoor air and contaminated indoor air is not only harmful to the human body, but also causes odor, and from bacterial and viral infections. It can cause great harm to the human body.

The background of the problem of indoor air quality (IAQ) is due to the increase in buildings installing energy saving devices and sealing seals for insulation of buildings in an effort to save energy and increase efficiency in various industrial fields. In fact, energy-saving buildings were built with a focus on preventing infiltration of air from the outside, and energy-saving industrial buildings intentionally reduced the ventilation volume to reduce the maintenance cost of the building. Due to reduced ventilation, indoor air is naturally polluted.

The main causes of indoor air pollution are the denser population, indoor living in modern society, and sealing of indoor spaces. Since the mainstream technology to remove chemical/biological hazards using a UV light source, optical plasma, or a combination of UV and sea wave filters is the mainstream, air purification using a sea wave filter can capture airborne dust, but sterilize microorganisms such as bacteria. , The disinfection function is difficult to expect, there is a hassle requiring periodic cleaning, and there is a problem that environmental pollution occurs due to the generation of secondary waste due to the replacement of the filter.

In addition, in the case of the air purification method using an optical plasma or a UV light source, the problem of the sea wave filter can be supplemented, but it has a problem that it can harm the human body and it generates ozone, which is a source of global warming.

Mold grows best when the temperature is 20~30℃ and humidity is 60% or more.In winter, heating and humidifier operation create an environment suitable for mold in a closed indoor space, and indoor air when the building insulation is insufficient. When the temperature difference between the wall and the wall is more than 15℃, condensation occurs in which hot and humid air collides against the cold wall and condensation occurs. Tiles, etc., are prone to moist mold habits.

Chlorine dioxide (ClO ₂ ) was first discovered by Humphrey Davy in 1814, and after being proposed as a disinfectant for water treatment by Berge in 1900, it has been widely used in drinking water sterilization, odor removal, and bleaching in the United States and Europe. In particular, since 1972, unlike chlorine, it has been found that chlorine dioxide does not react with organic pollutants in water to produce trihalomethane, a carcinogen.In particular, chlorine dioxide is a virus due to its strong oxidizing power despite its lower concentration than other chlorine-based compounds. By destroying the cell walls of infectious substances such as and bacteria, it can fundamentally prevent virus and bacterial infection and suppress the occurrence of fungi.

In addition, the U.S. Food and Drug Administration proposes the efficacy of reducing Listeria, E. coli O157:H7 (E. coli O157:H7), and Salmonella sp. to at least 1 in 100,000 levels as a standard for disinfectants. The efficacy of chlorine dioxide confirmed by the inventor of the present invention satisfies the regulatory standards of the Food and Drug Administration, and it was confirmed that it showed a better effect in eradicating Listeria bacteria that contaminated fruits and vegetables than any other sterilization methods currently available. The reason for targeting Listeria in this application is that it is particularly difficult to remove these bacteria compared to other types of pathogenic bacteria, and Listeria has strong vitality and is active enough to survive in refrigerators or freezers. It is known that it is difficult to remove.

Infectious diseases, such as viruses, bacteria, and fungi, are harmful to the human body, such as libraries, art galleries, performance halls, sports facilities, public transportation such as buses, railroads, subways, and taxis, and shopping centers such as hypermarkets, markets, and duty-free department stores. Viruses that occur in multi-use facilities such as movie theaters, large restaurants, public baths, group facilities such as schools, businesses, daycare centers, kindergartens, social welfare facilities, postpartum care centers, medical institutions, and living spaces or office spaces such as apartments and houses. Although it is a source that can prevent or eradicate bacterial infection or mold from the source of chlorine dioxide, a method for preventing or inhibiting the occurrence of virus or bacterial infection and mold using the source of chlorine dioxide has not been developed.

The prior art disclosed to sterilize closed indoor air such as toilets, multi-use facilities, group facilities, residential facilities, group facilities and offices, etc., is as follows.

Japanese Patent Application Publication No. 2005-343209 proposes a chlorine dioxide gas generating device capable of continuously performing stable deodorization, sterilization, and sterilization of indoor spaces such as hospital rooms and clean rooms.

Some Japanese patents mobilize chlorine gas to partially apply it to the field of sterilization, but in the present invention, sodium chlorite is used as a starting material for algicide, and pure chlorine dioxide water with excellent agicidal power is used by ion exchange by a cation exchange resin. The technical idea for killing or removing viruses, bacteria, and fungi in indoor spaces by mobilizing an automatic spraying device has not yet been presented, and even when the prior arts are applied in combination, the purpose of the present technology will be achieved. It is a new technology that cannot be used.

_{The present study addresses the problem that the dissolution rate of chlorine dioxide (ClO 2} ), which has excellent agicidal power, is less than 8,000 ppm in water, and has a high volatility, so that the dissolved amount of chlorine dioxide, which provides algicidal power, is rapidly reduced over time, resulting in a weakening of the agicidal power. To overcome, the chemically stable NaClO ₂ salt state is maintained until sprayed, and the chemically stable NaClO ₂ provides pure chlorine dioxide water with maximized algal activity through ion exchange reaction with cation exchange resin. It has the purpose of providing an automatic spraying device.

The automatic spraying device that provides pure chlorine dioxide water provided by the present technology is a kitchen, toilet, refrigerator in a closed indoor space such as residential spaces where people live, multi-use facilities used by many people, group accommodation facilities, residential welfare facilities, offices, etc. In order to overcome the limitations of the prior art that did not provide thorough sterilization or disinfection functions in facilities, etc., and at the same time reduce/dilute odors such as toilets and refrigerators to provide a fragrance, an algicide raw material solution mixed with aromas is used in the raw material storage unit. After being safely stored, a certain amount of raw material solution passes through the ion exchange reaction tank at the time required for sterilization and disinfection, _{is converted into ClO 2} and dissolved in water, and chlorine dioxide water is delivered to the place where sterilization or disinfection is required through the discharge and removal unit of the chlorine dioxide water storage tank. It has the purpose of providing a means for automatic spraying.

The technical idea of the present application disclosed as a means to achieve the above object is the power supply control unit, the injection amount control unit, the raw material storage unit and the ion exchange so that an aqueous solution of chlorine dioxide having an axicidal power can be automatically sprayed into an indoor space requiring sterilization or disinfection. A chlorine dioxide water supply device comprising a reaction tank, a chlorine dioxide storage tank, and a discharge unit may be used.

The chlorine dioxide water supply device to which the present technology is applied includes a power control unit 10 that is connected to an external power outlet to receive power or secures power by charging power of a battery to supply power by wire or wirelessly, and an indoor space An injection amount control unit 20 that controls to automatically inject a desired amount of chlorine dioxide aqueous solution at preset time intervals is included, and when the spray condition set in the injection amount control unit 20 is satisfied, the supply pump 24 is driven. The mixed solution of liquid sodium chlorite and aroma stored in the raw material storage and supply unit 30 is sent to the ion exchange reactor 40, and the ion exchange reactor has a structure with a cation exchange resin built-in, and the introduced sodium chlorite is a cation exchange resin. Pure chlorine dioxide (ClO ₂ ) is made by ion-exchanging with and is sent to the chlorine dioxide storage tank 50 by making it into a state of chlorine dioxide dissolved in water, and the chlorine dioxide storage tank is connected to the injection amount control unit 20 and the required amount The object of the present application can be achieved by a chlorine dioxide water and aroma supply device comprising a configuration in which the chlorine dioxide water and the aroma are discharged to a desired indoor space through the discharge passage 60 together.

_{Sodium chlorite (NaClO 2} ) stored in the raw material supply unit 30 of the chlorine dioxide water and aroma supply device to which the present technology is applied is made up of a mixed solution with an aroma in the range of 100 ppm to 7.5% by weight, together with the ion exchange reactor 40 The aroma passes through the cation exchange resin and rice as it is, and the sodium chlorite (NaClO ₂ ) is ion-exchanged with the _{cation exchange resin to produce pure chlorine dioxide (ClO 2} ).

In the ion exchange reactor 40 in the chlorine dioxide water and aroma supply device to which the present technology is applied, the cation exchange resin represented by R-SO ₃ H or R-COOH when the basic polymer matrix part of the ion exchange resin is represented by R _{It is used to ion-exchange only the cations of sodium chlorite, and liquid sodium chlorite (NaClO 2} ) and aroma having a concentration in the range of 100 ppm to 7.5% by weight are stored in the raw material storage and supply unit 30 in a mixed solution state. , The aroma is grapefruit, lavender, lemon, rose, rosemary, bergamot, cedarwood, citronella, anise, ginger, juniper berry, carrot seed, clary sage, clove bud, mandarin, mir, basil, cypress, sandalwood, Sweet Orange, Soupermint, Cinnaon, Eucalyptus, Ylang-Ylang, Jasmine, Geranium, Chamomile, Tea Tree, Peppermint, Nenoly, Lime, Lemongrass, Rose Geranium, Rosewood, Marjoram, Thyme, Pine, Palmarosa, Penal , Pettigrain, Pechuri, Frankincense is selected from one or more, and may be applied to be mixed with 0.01% by weight or less of the sodium chlorite solution.

Therefore, we sterilize in the indoor space where sterilization or disinfection is desired, such as kitchens, refrigerators, and toilets in enclosed indoor spaces such as residential spaces of people, multi-use facilities used by multiple people, group housing facilities, residential welfare facilities, offices, etc. /Because disinfection can be carried out, a chlorine dioxide water supply device that can automatically spray an aqueous solution of chlorine dioxide that provides algal control is connected to an external power outlet to receive power, or by securing power by charging power of the battery. Alternatively, a power control unit 10 for wirelessly supplying power is included, and an injection amount control unit 20 for controlling to automatically inject a desired amount of chlorine dioxide aqueous solution into the indoor space at a preset time or interval is included, and the injection amount control When the spraying condition set in the control unit 20 is satisfied, the supply pump 24 is driven to send a liquid mixture of sodium chlorite and aroma stored in the raw material supply unit 30 to the ion exchange reaction tank 40 and to the ion exchange reaction tank. A cation exchange resin is built-in structure, and the introduced sodium chlorite is ion-exchanged with the cation exchange resin to make pure chlorine dioxide (ClO ₂ ), and it is made into a state of chlorine dioxide dissolved in water, which is then transferred to the chlorine dioxide storage tank (50). It is characterized in that it comprises a configuration in which the chlorine dioxide water storage tank is sent and is connected to the injection amount control unit 20 so that the chlorine dioxide water and the aroma are discharged to a desired indoor space through the discharge passage 60 together with the required amount. It can be applied as an indoor space sterilization/sterilization method.

As discussed above, the present application is a bacterial infection such as viruses, bacteria, and fungi that occur in living spaces or office spaces such as multi-use facilities, collective facilities, residential facilities, collective facilities and offices, apartments, and houses, as disclosed in the background art. Conventional techniques for reducing or preventing damage can provide sterilization effect only in very narrow spaces, so it is highly unlikely to completely control or prevent indoor spaces contaminated with viruses, bacteria, and fungi. As the components of the device for anti-fungal and antifungal devices generally require expensive expenses, it is possible to secure a healthy and comfortable living space for most modern people living in an enclosed indoor space due to the economic burden for general consumers to purchase. On the other hand, the device capable of automatically spraying an aqueous solution of chlorine dioxide in the indoor space of the present application is pure gaseous with excellent agility when ion-exchanging _{sodium chlorite (NaClO 2) by a cation exchange resin.} When chlorine dioxide is made dissolved in water, and when the created chlorine dioxide water is sprayed into the indoor space with the device of the present application, chlorine dioxide (ClO2), which has excellent agility, is volatilized into the air, resulting in a large enclosed room due to convection. Distributed in a uniform concentration in the space, it is expected to greatly contribute to securing a pleasant and healthy indoor space as it is constructed so that fragrant aromas can be sprayed at the same time while eradicating viruses, bacteria and fungi contaminated in the indoor space.

In Korea, chlorine dioxide was recognized as a sterilization and disinfectant in drinking water in 1999-173 of the Ministry of Environment Notice No. 1999-173, and in 2005, sterilization of instruments, etc. It was designated to use chlorine dioxide as a disinfectant (200 ppm or less), and in 2008, the Ministry of Food, Agriculture, Forestry and Fisheries approved the designation and use of chlorine dioxide as a processing aid for organic products under the Food Industry Promotion Act No. 9759.

In addition, in the case of overseas, the World Health Organization (WHO) assigned chlorine dioxide, the safest standard among food additives in the field of safety, A1 grade, and the US Food and Drug Administration (FDA) was registered as a food additive in 1998. The U.S. Ministry of Environment (EPA) determined the suitability for use in 2006 and prescribed detailed uses and methods of use as EPA 738-R-06-007. In Japan, the Ministry of Health and Welfare regulated the oxidation and disinfection of drinking water, bleaching of wheat flour, disinfection of water, public baths, general It has been approved for use in antibacterial disinfection.

Therefore, considering that chlorine dioxide is approved to be applied to various fields as a material that is safe for the human body at home and abroad, this technology is designed to live in a closed indoor space, such as multi-use facilities, group facilities, residential facilities, group facilities, and offices. It is expected that modern people will greatly contribute to the use of providing a kill aid in minimizing or preventing human damage caused by viral or bacterial infections or mold outbreaks.

Hereinafter, the technical idea of the present application will be described in detail with reference to the drawings.

1 is a flow chart showing a flow chart for explaining the flow principle for a spray device capable of automatically spraying an aqueous solution of chlorine dioxide in an indoor space of the present invention. A power supply control unit 10 that controls the power supply as a means to provide a device capable of controlling the power supply, the injection amount control unit 20 that controls and controls the injection amount and injection time using the supplied power, and sodium chlorite (NaClO) in a solution. ₂ ) The raw material storage unit 30 for storing raw materials and aromas, the ion exchange reactor 40 for the mixture of sodium chlorite raw materials and the aroma mixture to achieve an ion exchange reaction with the cation exchange resin, and pure chlorine dioxide (ClO) ₂ ) Includes a chlorine dioxide storage tank (50) in which an algicide in the state of dissolved chlorine dioxide water is made and stored, and a discharge passage (60) configured to discharge both pure chlorine dioxide water and aromatic aromas with excellent agicidal power. It shows that it can be applied in a configuration.

The power supply control unit 10 includes a power input unit 11 receiving AC power such as 220V or 110V, a power control unit 12 that converts AC power to DC power, and converts the converted DC power to a main body control device. It may be configured to include a power supply unit 13 to supply, and in preparation for a situation in which it may be difficult to receive AC power, a charging circuit unit 14 capable of charging DC power and a power supply unit 13 after power has been charged. It may be applied in a configuration that additionally includes a battery 15 that can supply power through.

The injection amount control control unit 20 is for controlling the spraying of the chlorine dioxide aqueous solution into the indoor space, and a control device 21 that controls to spray a preset amount at a preset time interval, and a set time and a set amount of spray are recorded. It is shown that it can be configured to include a memory unit 22 that is stored and stored and a timer unit 23 that allows you to know the elapse of time, and the control device 21 has a predetermined time period through the timer unit 23. After confirming that it has elapsed, and when it is time to spray, the transfer pump 24 capable of controlling the supply amount is driven so that sodium chlorite and aroma raw materials can be supplied to the ion exchange reaction tank 40, and the ion exchange reaction in the ion exchange reaction tank 40 The resulting chlorine dioxide is dissolved in water, and an aqueous solution in which chlorine dioxide and aroma are mixed is controlled to spray a predetermined amount into the desired indoor space through the discharge passage 60 installed in the chlorine dioxide storage tank 50. It is natural that the end of the discharge passage is provided with a connection part that can be connected to the injection hose or the injection nozzle, etc., and can be used by one-touch coupling with the injection hose or the injection nozzle for convenience of use.

The raw material storage unit 30 is _{a storage for storing sodium chlorite (NaClO 2} ) raw materials and aroma fragrance raw materials, and there is no particular limitation and may be configured to store an aqueous sodium chlorite solution alone if an aroma fragrance is not required as needed. , In order to provide a masking effect against the rejection of odors inherent in the cation exchanged chlorine dioxide water in the ion exchange reactor 40, water-dispersible aromatic raw materials are stored, and the aroma is released when the chlorine dioxide water is sprayed. It is preferred that they are mixed together and applied to be sprayed.

When the sodium chlorite aqueous solution stored in the raw material storage unit 30 is diluted to a concentration of 23% by weight or less, it can be safely stored without the risk of explosion without chemical or physical changes. The concentration of sodium chlorate can be diluted and stored in a wide range of 100 ppm to 7.5% by weight, more preferably 500 ppm to 5.0% by weight of dilution and storage, and most preferably 0.5% to 4.5% by weight. It is advantageous to dilute and store in wt%, and when the concentration of sodium chlorite is diluted and stored to a concentration of 100 ppm or less, the concentration of chlorine dioxide (ClO ₂ ) in the final chlorine dioxide water ion-exchanged in the ion exchange reactor 40 As it is made at a low concentration of about 74 ppm, the possibility of eradicating contaminated bacteria, viruses and fungi in a large indoor space may be lowered.If the concentration of sodium chlorite is stored at a concentration of 7.5% by weight or more, an ion exchange reactor ( _{As the concentration of chlorine dioxide (ClO 2} ) of the final chlorine dioxide water ion-exchanged in 40) is made to a high concentration of about 5.6%, it has the advantage of being able to easily eradicate contaminated bacteria, viruses and molds in a large indoor space. However, the chlorine dioxide solution made by the present application is a strong oxidizing agent, and if chlorine dioxide is present in the indoor space at a high concentration, it may harm the respiratory tract and bronchi of the human body. It is desirable.

Therefore, when the raw material storage unit 30 is diluted to a concentration of 23% by weight or less of an aqueous sodium chlorite solution in a solution and introduced into the ion exchange reactor 40 filled with a cation exchange resin, the basic polymer having a network structure as shown in Reaction Formulas 1 to 2 below. Sodium in sodium chlorite diluted in water due to ion exchange while contacting a cation exchange resin that combines a _{sulfonic acid group (-SO 3} H) and a carboxyl group (-COOH) as an exchange group on the parent body (indicated by R). (Na) Cations are ion-exchanged by a cation exchange resin and placed in the chlorine dioxide water storage tank 50, and chlorine dioxide water and aroma are sprayed into the indoor space through the discharge passage 60 where sterilization/disinfection is required. It can provide a great effect in eradicating viruses, bacteria, fungi, etc. in a closed indoor space.

The aroma functions to eliminate the olfactory rejection of people living in indoor spaces due to the characteristic chemical odor of the chlorine dioxide water produced by the present application, and is stored together with sodium chlorite in a solution or a separate aroma storage unit is provided. It can be used, of course, can be selected and used according to people's preferences, and for this purpose, aromas in the range of 0.01 to 0.001% by weight compared to sodium chlorite in a solution may be mixed and used.

The aromas include grapefruit, lavender, lemon, rose, rosemary, bergamot, cedarwood, citronella, anise, ginger, juniper berry, carrot seed, clary sage, clove bud, mandarin, mir, basil, cypress, sandalwood, Sweet Orange, Soupermint, Cinnaon, Eucalyptus, Ylang-Ylang, Jasmine, Geranium, Chamomile, Tea Tree, Peppermint, Nenoly, Lime, Lemongrass, Rose Geranium, Rosewood, Marjoram, Thyme, Pine, Palmarosa, Penal , Pettigrain, Pechuri, Frankincense, one or more of the aromas can be selected and used.

Hereinafter, an embodiment to which the technical idea of the present invention is applied will be described, but it is natural that the technical idea of the present invention is not limited by the embodiment.

In order to implement the embodiment of the present invention, the start and stop times can be set to a 24-hour timer, and can be used, and an automatic air freshener sprayer and a dispenser indoor toilet deodorization multi-system that can adjust the spray amount up to 60 minutes per minute are purchased. Was used.

First, when the toilet deodorization multi-system is disassembled and a trap filled with cation exchange resin is installed before the fragrance outlet, a single sodium chlorite solution or a mixed solution containing a water-dispersible fragrance and sodium chlorite solution is sprayed through the outlet. It was configured to pass through a trap filled with a cation exchange resin.

For the antibacterial test, after cutting an acrylic plate to create an antibacterial test space of 100 cm × 100 cm × 100 cm, insert the medium inoculated with the test strain, and add sodium chlorite to the cation exchange resin in the indoor bathroom deodorization multi-system.

As shown in Table 1, when chlorine dioxide (ClO ₂ ) does not exist in a certain closed space, the reduction rate of bacteria was not confirmed, whereas an antibacterial test was performed on Escherichia coli, Pseudomonas aeruginosa, and pneumococcus according to the technology configuration according to the present application. As a result, it was confirmed that _{by supplying a disinfectant of chlorine dioxide (ClO 2} ) to the indoor space, it was possible to kill the contaminated bacteria in the indoor space as the reduction rate of bacteria was 99.9%. It can also be confirmed through the antibacterial test result report of KCL.

In addition, if chlorine dioxide and a masking agent are mixed and sprayed together, it is impossible to check the odor peculiar to chlorine dioxide. It is sprayed on to increase the sterilization and disinfection effect.

Therefore, as the technical idea of the present invention can completely eradicate all indoor spaces contaminated with bacteria by a spraying device capable of automatically spraying an aqueous solution of chlorine dioxide in the indoor space, the occurrence and prevalence of infectious diseases that are harmful to the public's health. It is expected that it will greatly contribute to the promotion and maintenance of the health of the people by preventing them.
