Description

RF plasma device capable of large-area air sterilization {Air sterilization device using RF}

The present invention relates to an air sterilization device using RFMA, and more specifically, to generate a large amount of ultrafine water droplets, which are unit water molecules, by dielectric heating using a plurality of RF feeders and to generate ion radical substances through plasma discharge. It relates to an RF plasma device capable of large-area air sterilization that can maintain a good residential environment by improving indoor air quality through sterilization of viruses and pathogenic bacteria in the air polluted by various pollutants.

Recently, as the time spent indoors has increased and the time spent on activities in indoor spaces has increased, interest in indoor air quality has increased. Looking at the causes of indoor air pollution, it can largely be caused by inflow into the room from the outside or by the indoor activities of residents. It can be seen as a case of self-generated pollutants, and if we look at the pollutants that flow from the outside air into the room, there are various pollutants, including fine dust and various air pollutants generated from vehicle operation and industrial sites, and are generated from the indoor air itself. Looking at the contaminants, radon and asbestos emitted from building materials, kitchen heating fuel, residents' daily activities and various household products, and formaldehyde, dust, and volatile organic compounds emitted from various household products. These include VOCs, nitrogen dioxide, carbon monoxide, cigarette smoke, and microorganisms.

These pollutants are known to cause various diseases, including respiratory diseases, so various technologies have been proposed to improve indoor air quality by efficiently removing pollutants to create a pleasant indoor environment. Representative examples include dry and wet methods. There is a type of air purifier.

The dry-type air purifier sucks in polluted air with a fan and forces it through a filter to filter out dust or bacteria in this process. Filters with different filtration densities are sequentially arranged to move dust from large particles to fine particles. It is designed to filter out, and if it is used for a long time, it may become a source of pollution due to contamination of the filter, so it must be replaced periodically.

In addition, a wet type air purifier is a method of removing dust particles by inertial collision direct absorption and diffusion by contacting dust particles floating in the air with droplet film bubbles, etc., which are created by spraying water on the sucked air. Compared to the dry method, a separate filter is not used, so it has the advantage of not requiring replacement. However, if the water is not changed frequently, contamination may occur due to bacterial growth and only relatively large particle contaminants can be treated, so the dust collection efficiency for fine dust is high. Due to this low disadvantage, it is not widely used. In particular, among various contaminants, bacteria and viruses, which pose a direct and fatal threat to human health, can cause infection between humans. Bacteria are made up of single cells and consume nutrients and produce organic matter, and viruses are nucleic acids such as DNA and RNA. It is made up of proteins and has a high transmissibility, mutations occur easily, and it takes a lot of time to develop a treatment.

Meanwhile, various pollutants, including viruses, contained in the air are known to cause various diseases, including respiratory diseases, so various technologies have been proposed to improve indoor air quality to effectively remove pollutants and create a pleasant indoor environment. There are two types of air purifiers: dry type and wet type.

Dry-type air purifiers suck in polluted air with a fan and force it through a filter to filter out dust or bacteria in the process. Filters with different filtration densities are sequentially arranged to remove large-sized dust and fine dust. It is designed to filter out. Here, the filter is a high-density filter with a dust collection efficiency ranging from 80% to 99.97% for particles of 0.3, and is efficient in collecting small particles. However, as the period of use increases and the dust particles deposited on the filter media increase, pressure loss occurs. As this increases, the air volume decreases and the purification capacity decreases, which not only imposes a large economic burden due to periodic replacement and disposal of filtration filters, but also has the disadvantage of making it difficult to treat contaminants such as viruses and bacteria with filtration alone.

A wet type air purifier is a method that removes dust particles by inertial collision, direct absorption and diffusion by contacting dust particles floating in the air with liquid droplets and bubbles generated by spraying water on the sucked air. This method is a dry type. Compared to other filters, it does not use a separate filter, so it has the advantage of not requiring replacement. However, if the water is not changed frequently, contamination may occur due to bacterial growth and only relatively large particle contaminants can be treated, resulting in low dust collection efficiency. Due to its disadvantages, it is not widely used.

Meanwhile, in recent years, the dry type air purifier has been additionally configured with a negative ion generator to neutralize positively charged polluted dust or cations. However, the negative ion generator has the disadvantage of causing harmful effects due to ozone generation when negative ions are generated. There is.

In addition, a device that promotes sterilization using ultraviolet light by installing an additional ultraviolet (UV) lamp has been proposed, but the sterilization and deodorization of pollutants can be achieved only after a certain contact time at a certain distance (e.g., within approximately 20 cm) from the ultraviolet light source. Therefore, sufficient air must be introduced into the device to obtain an appropriate effect, and the effect is limited depending on the degree of contamination or lifespan of the lamp used as a light source. Additionally, it has the disadvantage of not being able to remove contaminants attached to the interior of the facility rather than those floating in the air.

In addition, there are air purifiers with an ozone generator installed, but ozone sterilization uses ozone created by ionizing air or oxygen and is effective in removing pollutants in the air as well as attached pollutants and does not leave any residue, making it suitable for recent consumption. Although it is suitable for facilities that handle products of this type, in addition to the safety issue of indoor living when using ozone, there is a lack of complementary devices to effectively remove pollutants that frequently occur in the living environment. For general air sterilizers, the standard is set at 0.05ppm or less. According to what is generally known in the field of food science, when the ozone concentration is at least 0.5ppm, the death rate is over 99.9% within a few seconds to several minutes. The sterilizing power of ozone or active species at concentrations below this level is inevitably limited.

In this way, in the case of air purifiers using plasma generators, ozone generators, and ultraviolet lamps according to the prior art, the attachment and proliferation speed of microorganisms floating in the air must be considered, or in the case of facilities where pollutants are frequently introduced, the sterilizing power must be maintained stably. In reality, in the case of ozone or plasma, the reaction time is less than a few seconds, so they are destroyed as soon as they are created, so there is a limit to increasing the efficiency of removing microorganisms such as airborne bacteria in indoor air, as well as the frequent inflow of pollutants and the inflow of microorganisms into facilities, devices, and storage. If it adheres to the surface of an item and becomes attached bacteria, there is a disadvantage in that it is impossible to remove the contaminant. In other words, the air purifier according to the prior art can only lower the level of indoor pollution by removing dust or foreign substances by simply sucking in indoor air and passing it through a high-density filter material such as a HEPA filter to filter out contaminants. Even in the case of air purifiers equipped with plasma generators, ion generators, ultraviolet lamps, and ozone generators, continuous and effective sterilization and disinfection of pathogenic bacteria such as E. coli and salmonella, mold adhered to indoor walls or items, and various odor-causing substances. There was this difficult problem.

As another prior art, 'nano-bubble generator and nano-bubble generator' has been proposed through Korean Patent Publication No. 10-2019-0042081, and claim 1 includes 'housing; at least one blade; at least one first magnet; and at least one second magnet, wherein the housing includes: an entrance for receiving liquid containing macrobubbles; a first chamber operably disposed downstream of the inlet; a second chamber operably disposed downstream of the first chamber; and the at least one blade forming an outlet operably disposed downstream of the second chamber, wherein the at least one blade is positioned within the first chamber and, when in use, converts such macrobubbles into microbubbles contained in the liquid. cutting; the at least one first magnet is located within the second chamber; The at least one second magnet is associated with the second chamber, (i) the at least one first magnet and the at least one second magnet, wherein the polarity of the at least one first magnet is such that the polarity of the at least one second magnet is A nanobubble generator arranged so that the polarity is opposite, and (ii) at least one first magnet is movable with respect to at least one second magnet.' has been proposed.

However, the nanobubble generator according to the prior art is a technology that physically cuts microbubbles using a blade, and has limitations in splitting water droplets with a large unit surface area where a large number of water molecules are clustered, especially in the form of a single molecule. It had the disadvantage of being impossible to process.

As another prior art, an air purification device using streamer discharge has been proposed through Korean Patent Publication No. 10-2006-0085647. However, radicals are generated by streamer discharge, and the radicals are diffused by diffusion phenomenon. There is a problem in that it is difficult to improve sterilization performance by performing sterilization treatment, and also, because the discharge intensity must be increased to improve sterilization treatment performance, there is a problem in that a large amount of ozone is generated beyond the specified level. In addition, in order to improve the performance of sterilization treatment by radicals, a catalytic means is required, and this catalytic means is disposed in a direction perpendicular to the air passage on the discharge port side, thereby interfering with the air flow, increasing the differential pressure, and The structure of the discharge unit has a problem in that it impedes air flow and increases differential pressure. In addition, there are restrictions on the shape of the discharge unit, which makes it difficult to apply it to air purifiers of various shapes. Therefore, there is an urgent need to develop technology that can safely and quickly remove and sterilize various pollutants in the air and pathogens such as bacteria and mold.

Registered Patent No. 10-2059380 (2019.12.19.) Public Patent Publication No. 10-2019-0042081 (2019.04.23.) Registered Patent No. 10-2059380 (2019.12.19.) Registered Patent No. 10-2050278 (2019.11.25.) Publication Patent No. 10-2020-0001918 (2020.1.07.)

The present invention was created to solve the problems of the prior art as described above. The purpose of the present invention is to provide dielectric heating by supplying water droplets in clusters in the form of water vapor or wet steam within a large area and then emitting high-output RF. This converts cluster-shaped water droplets into monomolecular water molecules with excellent chemical reactivity with exposed dielectric dipoles that are not harmful to the human body and the environment, and also removes water molecules and oxygen molecules in the air through the plasma discharge process by RF. Plus and minus ions with sterilizing function are generated in large quantities in a large area. In particular, during the plasma discharge process, hydroxyl radicals and hydrogen radicals, which are types of activated chemicals, are generated, causing harmful substances such as pathogenic bacteria, mold, and influenza viruses in the air. The goal is to provide an RF plasma device capable of large-area air sterilization that effectively removes air by causing a chemical reaction.

That is, the present invention supplies moisture consisting of water droplets in the form of clusters in the form of water vapor or wet vapor to the chamber by a moisture supply module, and converts the moisture in the chamber into single molecules through dielectric heating by an RF feeder that radiates RF energy. Converts water molecules into water molecules, continuously generates ultra-fine water droplets in the form of single molecules, and induces plasma discharge by continuous RF energy radiation to generate ionic radical substances from water molecules, thereby dispersing these single-molecule water droplets and ions. Large-area air sterilization is designed to improve indoor air quality by sterilizing radical substances by mixing them with the outside air and discharging them indoors, allowing them to mix with indoor air and spread effective sterilizing power against contaminants in the air. The goal is to provide a possible RF plasma device.

Each of these RF suppliers irradiates RF with a supply energy of 0.1kw to 1MW into the inside of the reaction chamber to supply water vapor. It is characterized by being composed of an RF supply module that separates water molecules into fine water droplets through dielectric heating and generates ion radical substances consisting of hydrogen ions, hydroxyl ions, hydrogen radicals, and hydroxyl radicals through plasma discharge. .

As a preferred feature of the present invention, the main body is provided with an intake port for introducing external air and an outlet for discharging the introduced air to the outside, and on one side of the intake port there is a filtration filter for removing suspended substances in the air sucked in from the outside. is installed, and a blowing fan is installed on one side of the outlet to forcibly suck air through the intake port and discharge it to the outside; the main body is composed of unit water molecules discharged through the discharge hole and the outside flowing in through the main passage. A spiral-shaped vortex fin is formed on the inner surface of the main passage or the outer surface of the reaction chamber to mix air and discharge it, or the reaction chamber has discharge holes arranged in the direction of the spiral to discharge unit water molecules in the form of a vortex. .

As another preferred feature of the present invention, the RF supply module includes a plurality of RF suppliers that receive control signals and operate alternately to generate RF; a timer controller that controls the plurality of RF suppliers to operate sequentially for a set time; an RF meter that measures the RF output or reflection signal of the RF supply; A dielectric constant meter provided outside the reaction chamber to measure the concentration of single-molecule water molecules in the discharged gas; It consists of an RF controller that receives a measurement signal from either or both of the RF meter or dielectric constant meter and applies a control signal to the moisture supply module and RF supplier to maintain the output amount of RF or the amount of water molecules supplied to the inside within the set range. It lies in becoming.

The RF plasma device capable of large-area air sterilization according to the present invention radiates RF energy into a reaction chamber supplied with water droplets in the form of clusters in the form of water vapor or wet vapor to generate ion radical substances, which are activated species, through dielectric heating and plasma discharge processes. In addition to generating water vapor, it converts water droplets of water vapor into ultra-fine water droplets in the form of single molecules with a size of several angstroms, using these ultra-fine water droplets and ion radical substances to react with various harmful substances, including pathogens such as viruses, molds, and bacteria in the air. By doing this, it is possible to sterilize and remove large-area spaces, and as the residue after the reaction turns into water, a useful effect is expected to minimize the generation of environmental pollutants.

Here, repeated descriptions, known functions that may unnecessarily obscure the gist of the present invention, and detailed descriptions of configurations are omitted in order to not obscure the gist of the present invention.

Accordingly, the shapes and sizes of elements in the drawings may be exaggerated for clearer explanation.

Figure 1 is a conceptual diagram of the process of converting water (cluster-shaped water molecules), in which water molecules are clustered by hydrogen bonds, into single-molecule water molecules by RF dielectric heating according to the present invention.

The drawing is a conceptual diagram to explain the process by which cluster-shaped water molecules (10), which constitute moisture, are converted into single-molecule water molecules (20) by RF dielectric heating. Oxygen, which makes up water molecules, has a certain degree of electronegativity due to its relatively strong electron affinity, so it has a weak negative charge (δ ^- ), and hydrogen, which makes up water molecules, has relatively weak electrons. Because it has weak electronegativity due to affinity, it has a weak positive charge (δ ⁺ ).

In this way, the bond between oxygen, which has a weak negative charge (δ ^- ), and hydrogen, which has a weak positive charge (δ ⁺ ), forms hydrogen bonds and takes the form of a cluster. When heating liquid water using direct heating or convection heating, it is difficult to break the hydrogen bonds between water molecules, so the water molecules evaporate in the form of clusters (10). However, in the case of dielectric heating using RF (or electromagnetic waves), water molecule clusters are formed through dielectric heating by shaking the positive charge of hydrogen (δ ⁺ ) and negative charge of oxygen (δ ^- ) carried by water molecules using electric field energy. From (10), it can be separated into single water molecules (20).

Figure 2 is a conceptual diagram of the conversion of moisture (cluster-shaped water molecules) into single-molecule water molecules by RF dielectric heating according to the present invention. After the water molecule cluster 10 is converted into single molecule water molecules 20 by RF dielectric heating, when further RF energy is irradiated, a plasma discharge phenomenon occurs, and in this process, single molecule water molecules are formed. (20) has excellent chemical reactivity, which has the effect of causing chemical reactions to occur quickly, and forms water as a by-product, thereby reducing damage from environmental pollution.

Figure 3 is a schematic diagram of a chemical reaction for the conversion of moisture (cluster-shaped water molecules) into single-molecule water molecules by RF dielectric heating according to the present invention. It shows an example in which a unit cluster consisting of n water molecules was converted into n single molecule water molecules by RF dielectric heating.

Figure 4 is a schematic diagram illustrating the chemical reaction of ultrafine water droplets as an example of the present invention. This is an example of the chemical decomposition of toluene or chloroform, which are one of the environmentally hazardous substances, and shows the process of decomposition when it encounters a single molecule of water with excellent chemical reactivity.

Figure 5 is a conceptual diagram to explain the conversion of moisture into water molecules and reforming into ion radical materials by RF heating in the RF plasma device capable of large-area air sterilization according to the present invention.

Figure 6 is a conceptual diagram of measuring the concentration of ultrafine water droplets according to the present invention. A water molecule (1) in the form of a single molecule can be recognized as a unit dielectric molecule (2) in which positive and negative charges are polarized due to the positive charge of hydrogen (δ ⁺ ) and the negative charge of oxygen (2δ ^- ). When the voltage applied to two electrode plates is measured for these dielectric molecules, a difference in the voltage measured occurs between water molecules in the form of clusters (10) and single molecules (1), resulting in a single molecule. It becomes possible to measure the concentration of water molecules in molecular form.

Figure 7 is a diagram schematically showing the configuration of an RF plasma device capable of large-area air sterilization according to the present invention.

In the drawing, a main body 30 is arranged in the form of a double pipe to form an outer body and provides a main chamber 31, which is a hollow space inside. A reaction chamber 40 is provided with a reduced diameter inside the main body 30 and has a plurality of discharge holes 41 penetrating the outer surface, and supplies water vapor, which is a moisture cluster, to the inside of the reaction chamber 40. The water supply module 50 for the water supply module 50, and the water cluster in the form of water vapor (a) supplied into the inside of the reaction chamber 40 by the water supply module 50 are separated into unit water molecules by dielectric heating by RF. An RF plasma device capable of large-area air sterilization is shown, which consists of an RF supply module 60 that is provided on one side of the reaction chamber 40 and outputs RF energy as an element for converting RF energy into ultrafine water droplets (b). there is.

With reference to the drawings above, the configuration of the RF plasma device capable of large-area air sterilization according to the present invention will be described in detail.

First, the present invention largely includes a main body 30 forming the outer body, a reaction chamber 40 accommodated inside the main body 30, and supplying water droplet clusters in the form of water vapor or wet steam to the inside of the reaction chamber 40. To sterilize and disinfect harmful substances, including viruses and bacteria in the air, through the process of radiating RF to the water vapor supplied into the moisture supply module 50 and the reaction chamber 40 and separating it into unit water molecules. It consists of an RF supply module 60 to induce reforming with possible hydrogen ions, hydroxyl ions, hydrogen radicals, and hydroxyl radicals.

The main body 30 is provided with an intake port 34 on one side to introduce air from the outside, and on the other side, ultrafine water droplets (b) converted into single-molecular water droplets by irradiating water vapor with RF and the introduced air. It is a cylindrical structure with an outlet 33 for discharging the mixed gas c to the outside, and provides a main passage 31.

Meanwhile, in the present invention, it is exemplified that it is provided in a hollow tube shape, but the shape may be modified in various ways as long as it has a structure that provides a passage connecting the inlet 34 and the outlet 33.

This main body 30 is equipped with various known filtration filters 35, such as a HEPA filter, on the inlet 34 side to remove suspended substances in the air flowing in from the outside, and on the outlet 33 side, the inlet 34 It is a configuration in which a blowing fan 36 is installed to forcibly suck air through the air and discharge it to the outside through the outlet 33.

In addition, the main body 30 in the present invention has a spiral-shaped vortex fin (not shown) protruding from the inner surface so that a vortex is generated when the air induced from the intake port 34 flows toward the discharge port 33. It is also possible to become This is to ensure that the ultrafine water droplets (b) generated in the reaction chamber 40, which will be described later, can be smoothly mixed with the air flowing in the main passage 31 of the main body 30.

In addition, the internal pressure of the main body 30 can be adjusted within 0.8 to 1.2 atmospheres in order to smoothly mix the ultra-fine water droplets (b) with the air introduced from the outside, and for this purpose, a pressure pump for pressure adjustment is installed on one side of the outside. is connected, and the pressure pump at this time can be configured to be connected to a known microcomputer controller and receive a control signal to control its operation.

The reaction chamber 40 is disposed on the main passage 31 of the main body 30, and is a hollow pipe-shaped member with a relatively reduced diameter, with both ends shielded and a plurality of devices spaced at equal intervals on the outer surface. A discharge hole 41 is formed through it. This reaction chamber 40 is configured to receive water vapor (a) and RF energy from a moisture supply module 50 and an RF supply module 60, respectively, on one side, which will be described later.

Meanwhile, the reaction chamber 40 in the present invention is preferably made of a metal material or an electromagnetic wave shielding structure to prevent RF energy irradiated inside from leaking.

In addition, the reaction chamber 40 may be additionally equipped with a heat generating heater inside or outside that generates heat by receiving power to increase the temperature of the moisture supplied inside. In this case, the heat generating heater will be described later during the heating process. It serves to raise the temperature to a certain level through heater heating rather than dielectric heating by the RF supply module 60.

Meanwhile, the reaction chamber 40 allows ultrafine water droplets (b), which are unit water molecules discharged through the discharge hole 41, to form a vortex when discharged into the main passage 31, so that they can be easily mixed with external air. It is desirable to form a spiral-shaped vortex fin (not shown) on the outer surface or to arrange a plurality of discharge holes 41 formed through the hole at equal intervals in the direction of the screw line.

The moisture supply module 50 is connected to one side of the reaction chamber 40 and is an element for supplying moisture in the form of cluster-shaped water droplets into the reaction chamber 40 in the form of water vapor or wet steam.

This moisture supply module 50 can largely use a water tank and an ultrasonic oscillator or a heated evaporator that receives water supplied from the water tank and changes it into water vapor or wet steam. These ultrasonic oscillators and a heated evaporator are used by known technologies. Since it may be implemented, detailed description is omitted.

In addition, the moisture supply module 50 may use a nozzle sprayer for spraying high-pressure water through a nozzle, or a natural vaporization type evaporator, etc. In addition, if it has the technical feature of supplying moisture in small particles, It may also be possible to apply various known technologies.

Meanwhile, the present invention proposes that any one or a combination of an ultrasonic oscillator, a heated evaporator, and a nozzle sprayer capable of generating a large amount of water vapor is used, and the temperature of the water vapor at this time is 50 to 150 degrees Celsius, which is higher than room temperature. °C, and this is because when high-temperature moisture clusters are supplied, the reforming action by dielectric heating by the RF supply module 60, which will be described later, becomes easy.

The moisture supply module 50 configured as described above is configured to supply water vapor into the interior of the reaction chamber 40, and the water vapor supplied in this way is converted into unit water molecules by RF energy supplied from the RF supply module 60, which will be described later. It is split into fields.

The RF supply module 60 includes a plurality of RF suppliers 61 installed on one side of the reaction chamber 40 and controlled to operate alternately, and each of these RF suppliers 61 supplies supply energy of 0.1 kw to 1 MW. By outputting the RF energy to the inside of the reaction chamber 40, the water vapor supplied by the water supply module 50 is separated into unit water molecules, which are fine water droplets, through a dielectric heating action, and in this process, hydrogen ions, Hydroxyl ions, hydrogen radicals, and hydroxyl radicals are generated.

This RF supply module 60 largely includes a plurality of RF suppliers 61, a timer controller 62 that sequentially controls the operation of these RF controllers 65, and measures the output amount or reflection amount signal of the RF controller 65. It consists of an RF meter 63 that measures the concentration of ultrafine water droplets (b), a dielectric constant meter 64 that measures the concentration of ultrafine water droplets (b), and an RF controller 65 that is a control element for controlling the RF output amount and the unit water molecule supply amount.

The RF feeder 61 is comprised of a plurality of RF feeders 61, which sequentially generate RF energy. When one RF feeder 61 is configured, the service life is drastically shortened as well as the durability decreases due to continuous use. Therefore, in the present invention, To solve the problem, we propose an RF supply module 60 consisting of two or more RF suppliers 61, which are connected to a circuit to the timer controller 62 and controlled to operate sequentially for a certain period of time. .

The timer controller 62 is an element that controls the plurality of RF suppliers 61 to operate sequentially for a set time, and may be integrated into the RF controller 65, which will be described later.

The RF measuring device 63 is a sensing element for measuring the RF output amount or reflection amount signal of the RF supply 61, and is installed on one side of the inside of the reaction chamber 40 and connected to a detection signal circuit to be described later to the RF controller 65. ) operates to authorize.

The dielectric constant meter 64 is a sensing element installed on one side of the inside or outside of the main body 30 to measure the concentration of water molecules in the form of single molecules contained in the mixed gas (c). That is, to measure the concentration of ultrafine water droplets (b), to measure the concentration of water molecules in the form of single molecules contained in the mixed gas (c) that passed through the outlet 33 of the main body 30 or the outlet 33. On one side of the interior of (33), a circuit is connected to measure the concentration of single-molecule water molecules contained in the mixed gas (c) before being discharged to the outside and apply the concentration to the RF controller 65, which will be described later.

The RF controller 65 is connected in a circuit to either or both the RF meter 63 or the dielectric constant meter 64 to receive measurement information, and based on the detection information, the output amount of the RF or the inside of the main passage 31. It is a control element that applies a control signal to the water supply module 50 and the RF supplier 61 to maintain the amount of water molecules supplied to the furnace within the set range.

The RF supply module 60 configured in this way irradiates RF with a supply energy of 0.1kw to 1MW and separates it into unit water molecules through a dielectric heating action on the water vapor supplied through the water supply module 50. In this process, hydrogen ions, hydroxyl ions, hydrogen radicals, and hydroxyl radicals are generated and supplied into the main passage 31 of the main body 30.

In other words, the RF supply module 60 irradiates RF to moisture clusters in the form of water vapor or wet vapor, thereby causing dielectric heating in the moisture clusters, and as a result, they are reformed into hydrogen ions, hydroxyl ions, hydrogen radicals, and hydroxyl radicals. As is widely known, the reformed hydrogen ions, hydroxyl ions, hydrogen radicals, and hydroxyl radicals remove contaminants in the air, and in the present invention, the main body ( As it flows into the main passage 31 of 30, it reacts with and removes contaminants in the external air sucked through the main passage 31.

In addition, the mixed gas (c), which is a mixture of ultrafine water droplets (b) and external air, in the main passage 31 of the main body 30 contains a large amount of unit molecule water droplets, as well as hydrogen ions, hydroxyl ions, hydrogen radicals, and hydroxyl radicals. Since it contains, when this mixed gas (c) is supplied indoors, it mixes with indoor air and spreads sterilizing power, making it possible to remove harmful substances, including bacteria and viruses, contained in indoor air within a short period of time.

The operation of the RF plasma device capable of large-area air sterilization according to the present invention configured as described above will be described as follows.

The present invention supplies water droplets in the form of clusters in the form of water vapor or wet vapor to the inside of the reaction chamber 40, and the RF supply module 60 radiates electromagnetic wave energy to the water droplets in the cluster form to generate electricity contained in the water molecules. By stimulating the dipole, hydrogen bonds with adjacent water molecules are broken, resulting in the creation of ultrafine water droplets (b), which are single-molecule water molecules, and plasma is formed by the continuous release of RF energy. In this process, hydrogen Ion radical substances composed of ions, hydroxyl ions, hydrogen radicals, and hydroxyl radicals are generated.

That is, according to the present invention, when high-temperature cluster-shaped moisture is supplied to the inside of the reaction chamber 40 and high-output RF is emitted from the RF supplier 61 constituting the RF supply module 60, the water vapor or Cluster moisture in the form of wet steam is separated into unit water molecules by dielectric heating, creating positive and negative ionized substances, ions made of hydrogen radicals and hydroxyl radicals, which are activated species, and radicalized substances.

In this way, ions and radicalized substances, including ultrafine water droplets (b), which are reformed unit water molecules, are continuously generated in large quantities, and are passed through the discharge hole 41 of the reaction chamber 40 to the main passage of the main body 30. (31). At this time, contaminants including viruses contained in the external air flowing into the main passage (31), that is, the air to be purified, are ionized or radicalized hydrogen ions and hydroxyl ions. , is quickly removed while reacting with hydrogen radicals and hydroxyl radicals.

In addition, the mixed gas (c), which is a mixture of external air, ultrafine water droplets (b), and radicalized substances introduced into the main body 30, flows into indoor air and ashes through the outlet 33 of the main body 30. By disseminating sterilizing power while mixing, it is possible to sterilize large areas of indoor air and remove harmful substances, thus improving indoor air quality and maintaining a good living environment.
