In the severe situation due to various harmful pollutants in the modern society and infectious pathogens caused by viruses, bacteria, gompies, etc., sterilization of air and surface (human body and objects) can reduce disease and hospital antibiotics by 70%.

Most of the people have neglected the concept of air sterilization concept and the importance of the surface (human body, object) sterilization, bar, reduce various pathogens and antibiotics, prevent infectious diseases, for the health of the people, the present invention is an infectious disease and It is designed to sterilize for cleanliness of air and surface (human body, object) for hygiene

The sterilization of air was conventionally a method of purifying the air with a simple filter type air purifier. The cleaning of the surface (human body and object) is generally used as cleaning water and chemicals such as disinfectant disinfectant, but this is limited to experts in medical practice. General public has difficulty in medicine.

In addition, direct irradiation of UV germicidal lamps harms the skin and human body, and it is difficult to commercialize due to rejection in most cases because the sterilization effect is lost when a certain distance is dropped.

The present invention produces OH radicals, which are natural substances, and spreads them into the air through photochemical action of ultraviolet rays and photocatalysts, and oxidizes and decomposes various pollutants on air and surfaces (objects and humans).

The present invention was devised in consideration of the above situation, and its purpose is to enable sterilization for sanitation of contaminated air and surfaces (human body and objects) without any harm to the human body.

It is designed to produce large amount of hydroxyl group (hydroxyl radical) which is oxygen anion-based sterilizing gas by photochemical action of UV lamp coated with titanium dioxide photocatalyst and photocatalyst pad.

That is, when strong sterilizing ultraviolet rays are irradiated on the surface of the photocatalyst, oxygen and water molecules in the air passing through them are broken and become neutral gas ions. Among these ions, hydroxyl ions have a strong sterilizing power, and are blown by a fan. Oxidative decomposition (sterilization, disinfection) of air and all contaminants on surfaces.

The present invention uses the principle of photochemical action of plasma, ultraviolet ray and photocatalyst to produce hydroxyl group (hydroxyl radical) which is a natural sterilizer (gas).

The principle of the construction and operation of the present invention is explained in detail.

◎ hydroxyl group (OH Radical / original name, hydroxyl radical)

· Hydroxyls are being made little by little in our natural air.

This is an ionization phenomenon in which ozone breaks down due to photochemical action when ozone in the atmosphere meets ultraviolet (O3) ultraviolet rays. One oxygen atom (O) is released and combines with hydrogen atoms (H +) from water vapor (H2O) in the atmosphere to generate hydroxyl groups. .

The hydroxyl group is generated even when UV and photocatalysts are combined. The hydroxyl group (OH) is a kind of oxygen anion-based substance that is produced in the plasma state of the fourth substance when high and powerful energy is applied. It is a very harmful natural substance

Hydroxyl groups (OH) are directly involved in air and surface contaminants, which in turn undergo oxidative decomposition by changing back to the intermediate hydroparoxy radical (HO2).

This chain reaction breaks down almost all pollutants into very safe water (H2O) and carbon dioxide (CO2), making them harmless to the human body. Among the existing substances, the oxidizing power of OH (sterilization and disintegration) is stronger than fluorine, twice as strong as chlorine, and about 1 times higher than hydrogen peroxide (H2O2). It is more than 57 times more sterilizing, and recent US experiments have demonstrated that hydroxyl (OH) has an oxidation rate of 2000 times faster than ozone and 180 times faster than ultraviolet. It is not toxic or harmful to human body like fluorine, chlorine ozone and ultraviolet.

Thus, hydroxyl groups, which are harmless to humans and animals, are among the most effective and safe natural substances of any disinfectant that can be used to destroy fungi, bacteria and viruses.

These substances react chemically with pollutants and soon return back to carbon dioxide and water, and the hydroxyl groups, which are combined with the pollutants and regenerated after decomposition, continue to act as strong oxides.

The hydroxyl group rapidly penetrates into air and surface pathogens (in nanoscale) and continues to disintegrate rapidly, taking away ions from various contaminated media. This is scientific evidence that hydroxyls have strong bactericidal and chemical degrading abilities.

The hydroxyl group oxidizes and decomposes all 0.001 microorganisms, viruses, and fungi that are parasitic on the surface, and the self-diffusion rate is very fast and the reaction rate is very fast (reacts at 1 nano unit speed).

Oxygen plasma substances interact with contaminants and are mostly volatilized to safely reduce contaminants with carbon dioxide (CO2) and water (H2O)

Ultraviolet radiation further leads to the release of electrons that bind molecules of organic material to generate free radicals.

The radicals thus produced can react with oxygen to produce hydrogen peroxide ions.

Hydrogen peroxide oxidation leads to stronger oxidation of organic compounds and promotes solidarity

The remaining hydrogen (H) ions after oxidation react with the surrounding water vapor (H2O), creating a new hydroxyl group (OH), which is a much more powerful oxide.

This hydroxyl (OH) has a very strong oxidizing power with one more electron without being easily broken down.

Hydroxyl groups (OH) are very effective in destroying organic pollutants because they deprive hydrogen atoms (H) from organic substances that are harmful to the human body, reduce them to water (H2O), and eventually collapse them from the remaining carbon ions (C).

At this time, the hydrogen ions (H) remaining in the process of decomposing organic molecules can continuously lead to a chemically stronger hydroxyl group (OH) as long as organic pollutants exist while retaining higher oxidizing power.

It takes more than 10 hours to remove biological contaminants (viruses, bacteria, molds, etc.) from the surface of the material with ozone generated by corona discharge only, and it takes 1 minute 30 to obtain the same result with only 254 nanometer sterilizing UVC ultraviolet light. It takes more than 90 seconds, but when combined with strong ultraviolet wavelength and plasma, the same result can be seen in 20 seconds.

· The effect of hydroxyl group is sterilization and disinfection of all biological contaminants in the air and the surface (objects and human body) and oxidatively decomposes all biological contaminants and pathogens bacteria, viruses and molds.

◎ Plasma

All materials on earth are solid, liquid, and gas, but there is a fourth material, plasma, and gaseous ions which are electrically neutral because gas molecules are separated into electrons and atomic nuclei.

One of these ions, called the hydroxyl group, is the fastest and complete sterilization of air and all biochemical contaminants on the surface.

When the surface of a titanium dioxide photocatalytic semiconductor is irradiated with ultraviolet rays with a strong sterilizing power of nanometer wavelength, oxygen and water molecules in the air passing around are broken and a plasma state is formed.

The present invention utilizes this plasma phenomenon that occurs when light (ultraviolet rays) and a photocatalyst are combined.

◎ Photochemical

Sufficient light energy in the ultraviolet wavelength range below 400 nanometers refers to the photochemical action of oxygen and water molecules in the air

When the high, intense bandwidth of the ultraviolet spectrum is combined with the photocatalyst (TiO2), the photoplasma principle occurs on the surface of the molecules to ionize the molecules to create a disinfectant by the chemical action of the ions.

Only oxygen molecules (O2) and water molecules (H2O) contained in the inlet air inside the sterilizer are picked up and separated by optical low temperature plasma reaction to hydroxyl groups (OH-) and activated oxygen anions (O2-, O3-, O3), respectively. The negative ions generated by the change are spread out by the fan.

Among the anions that go out, especially the hydroxyl group (OH-) has much stronger sterilizing power than chlorine (Cl2) and ozone (O3), so all pathogenic bacteria in the air and surface (objects, human body) and filamentous fungi such as viruses and fungi It finds and sterilizes, disinfects and causes oxidative decomposition of chemical gases that are harmful to health.

The indoor air and the surface (object, human body) are filled with various harmful substances, and the released plasma ions combine with the harmful substances on all surfaces (object, human body) to start the reaction.

Plasma ions are superoxides, mono-oxygen anions (O-), ozone (O3), and oxygen atom (O) hydroxyl groups (OH-), respectively, which cause an appropriate oxidation reaction with each pollutant.

The substances surrounding the polluted hazardous substances are (OH-, O-, O2-, O, O3), H +, and they react with oxidation and reduction.

Most of the pollutants are CHx (chemical hydrocarbons) and bacteria (biological substances), which are CH2O (carbohydrate) organisms (OH-, O2-, O-, O, O3).

The ions combine with each other to form a chemical reaction by combining with the (C, H, O) atoms, which are the main components of the pollutant, and the plasma ions return to their stable molecular water (H2O) and carbon dioxide (O2) molecules, respectively. Continue to realize perfect sterilization

The hydroxyl group (OH-), a plasma germicidal ion, causes oxidation with air and surface pollutants and mineralizes and destroys the pollutants. Some hydroxyl groups (OH-) fly back into the sterilizer and combine with other electrons (e-) to produce more powerful hydroxyl radicals that continue to oxidize.

Cold plasma and photoionization using photochemical principles can simultaneously remove organic compounds and biological contaminants from air and surfaces. Photocatalytic reactions generally require the use of light in the ultraviolet spectrum range, and strong and sufficient UV light must be able to react with photocatalysts to make hydroxyl groups useful for the destruction of contaminants.

The present invention is an ultraviolet lamp with sufficient light energy, which leads to the optical separation of oxygen and water molecules in the air to produce low-temperature plasma separated by electrons and atomic nuclei.

Ultraviolet debt can disrupt the bonds between the electrons of an organism's molecules as powerful energies between 100 and 280 nm.

LJV wavelengths in the 100-280 nm band not only disrupt the binding of organic compound electrons, but also initiate low-temperature plasma formation.

High-energy gaseous photoplasma is further enhanced by high-energy gaseous states, resulting in highly reactive, excited (excited) electrons, molecules, and ionized gaseous free electrons.

The hydroxyl groups in these ionized electrons can destroy organic contaminants more reliably than any other means.

The present invention adopts more special UV sterilization lamp (photocatalyst coated UV lamp) than conventional UV sterilization lamp, and special UV lamp combined with photocatalyst has sufficient light energy to generate plasma ions.

◎ photocatalyst

· Environmental material that transforms various pollutants into harmless ones as a medium that promotes chemical reactions of other organic substances without changing itself by receiving light energy. The best photocatalytic function under ordinary conditions is the crystal structure anatase. It is a type Tio2 (carbon dioxide), and it is necessary to combine nanotechnology because it needs to make particles as small as several nanometers to maximize its function.

Titanium dioxide (Tio2) photocatalyst is an n-type semiconductor, and when it receives light (ultraviolet rays), electrons (e-) with electricity and holes (h +) with electricity are formed.

e- produces O2- (superoxide anion) and holes (h +) produce hydroxyl radicals (OH-) and superoxides (O2-), which are powerful oxidizing hydroxides (OH Radicals).

These hydroxyl radicals and superoxides oxidize and decompose the organic compounds into water (H2O) and carbon dioxide (CO2). Effect lasts semi-permanently

In order to maximize the photocatalytic function, it is necessary to make particles as small as several nanometers, so it is necessary to combine nanotechnology.
