Description

RF plasma multiple air sterilizer {RF plasma multiple air sterilizer}

The present invention relates to an RF plasma multi-air sterilization device. More specifically, the present invention relates to an RF plasma multiple air sterilization device, and more specifically, to continuously radiate RF into each space connected to partitions against moisture in the form of clusters in the form of water vapor or wet vapor through dielectric heating and plasma discharge. In addition to converting cluster-shaped moisture into unit water molecules, in this process, ion-radical substances consisting of hydrogen ions, hydroxyl ions, hydrogen radicals, and hydroxyl radicals are generated, thereby sterilizing viruses and pathogens in the air, thereby improving indoor air quality. This relates to the RF plasma multi-air sterilization device that allows for improvement.

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 there is an advantage in that there is no need for 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 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 of removing 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 floating 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 such as a HEPA filter to filter out the 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. 20-2019-0042081, and claim 1 includes 'housing; at least one blade; at least one second magnet; and at least one second magnet, wherein the housing includes: an entrance for receiving liquid containing macrobubbles; a second chamber operably disposed downstream of the inlet; a second chamber operably disposed downstream of the second 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 second chamber and, when in use, converts such macrobubbles into microbubbles, the microbubbles contained in the liquid. cutting; the at least one second magnet is located within the second chamber; The at least one second magnet is associated with the second chamber, and (i) the at least one second magnet and the at least one second magnet are configured such that the polarity of the at least one second 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 second magnet is movable with respect to the 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. 20-2006-0085647. 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 in addition, in order to improve sterilization treatment performance, the discharge intensity must be increased, so 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. 20-2059380 (2019.12.19.) Public Patent Publication No. 20-2019-0042081 (2019.04.23.) Registered Patent No. 20-2059380 (2019.12.19.) Registered Patent No. 20-2050278 (2019.11.25.) Public Patent No. 20-2020-0001918 (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 partition and connect spaces where moisture is supplied in the form of clusters made of water vapor or wet steam, and to irradiate RF in each of these partitioned spaces.

The aim is to provide an RF plasma multi-air sterilization device that continuously generates radical substances and uses them to effectively remove contaminants in the air.

In other words, the present invention converts water droplets supplied in the form of water vapor or wet vapor into single molecule water molecules through the RF heating action, and at this time, the single molecule water molecules have a very large unit surface area, unlike water droplets in the form of water vapor or wet vapor. Because the dielectric dipoles of large water molecules are exposed, they have excellent chemical reactivity and are non-hazardous. In addition, by continuously supplying RF energy, a plasma discharge is generated, so that water molecules in the form of single molecules pass through the discharge process. It has the characteristic of generating hydrogen ions, hydroxyl ions, hydrogen radicals, and hydroxyl radicals.

Another object of the present invention is to smoothly generate water droplets in the form of single molecules through dielectric heating and plasma discharge of moisture in the form of water vapor or wet vapor using an RF feeder, and to provide a compact size so that plasma discharge can be easily formed. The aim is to provide an RF plasma multi-air sterilization device consisting of a plurality of sterilization modules.

In other words, in order to induce a plasma discharge using RF, if the discharge space is large, it is necessary to install several expensive high-output RF feeders, and there is a disadvantage in that the consumption of electrical energy is large and maintenance is difficult. Therefore, the present invention A configuration was proposed that connects multiple sterilization modules in series to provide a discharge space of .

It is characterized by consisting of a control module that controls the supply amount of water vapor or wet steam and the output amount of RF by applying a control signal to one or both of the first and second moisture suppliers and the first and second RF suppliers.

As a preferred feature of the present invention, the first main body is provided with a first intake port for introducing external air and a first outlet for discharging the introduced air to the outside, and on one side of the first intake port, the air sucked in from the outside is provided. A filtration filter to remove suspended solids is installed, and the second body is provided with a second intake port through which the mixed gas generated in the first body flows and a second outlet for discharging the introduced mixed gas to the outside. A blowing fan is installed on one side of the second outlet to forcefully suck in external air through the second intake port and discharge it through the second outlet;

The first and second bodies mix ultra-fine water droplets composed of unit water molecules and ion-radical substances discharged through the first and second discharge holes, respectively, with external air and mixed gas, so that the first and second bodies can flow. , 2 A spiral-shaped vortex fin is formed on the inner surface of the main body or the outer surface of the first and second reaction chambers, or the single molecule water droplets and ion-radical substances generated in the first and second reaction chambers are discharged while forming a vortex. The first and second discharge holes are formed in a plurality of arrangements in the direction of the thread.

As another preferred feature of the present invention, the control module includes an RF meter installed inside each of the pre- and post-treatment sterilization modules to measure the RF output amount or reflection amount signal, and one inside or outside of the first and second reaction chambers.

The plasma air sterilization device using RF plasma according to the present invention irradiates RF energy into a reaction chamber supplied with water vapor, generates plasma and converts water vapor droplets into single-molecule ultrafine water droplets of several angstroms in size. Using fine water droplets, it is possible to remove various harmful substances, including pathogens such as viruses, molds, and bacteria in the air, and as the residue after the reaction turns into water, it is a useful effect that can minimize the generation of environmental pollutants. I'm looking forward to it.

In other words, by RF energy, water vapor is converted into ultrafine water droplets in the form of single molecules with a size of several angstroms, and in this conversion process, ions of hydrogen ions, hydroxyl ions, hydrogen radicals, and hydroxyl radicals are generated through plasma discharge by RF energy. -As radical substances can be generated, the advantage of the properties of ultrafine water droplets in the form of single molecules, hydrogen ions, hydroxyl ions, hydrogen radicals, and effective removal of harmful substances by hydroxyl radicals is expected.

No.

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. Embodiments of the present invention are provided to more completely explain the present invention to those skilled in the art. 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) constituting 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 The molecules 20 are ultra-fine water droplets and have excellent chemical reactivity, so they have the effect of quickly causing chemical reactions, and form 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) in water vapor or wet vapor 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 for explaining the conversion of moisture into water molecules and reforming changes into ion-radical substances by RF heating in the plasma air sterilization device using RF plasma 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 measuring the voltage applied to two electrode plates, a difference in the voltage measured between water molecules in the form of clusters (10) and single molecules (1) occurs, resulting in a single dielectric molecule. It becomes possible to measure the concentration of water molecules in molecular form.

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

In the drawing, a pre-treatment sterilization module 30 consisting of a first body 31, a first reaction chamber 33, a first moisture supplier 35, and a first RF supplier 37, a second main body 41, and a first RF supplier 37 are shown. A post-treatment sterilization module (40) consisting of a second reaction chamber (43), a second moisture supplier (45), and a second RF supplier (47), and an RF meter (51), a dielectric constant meter (53), and an RF controller (55). An RF plasma multi-air sterilization device consisting of a control module 50 is shown.

With reference to the above drawings, the configuration of the RF plasma multiple air sterilizing device according to the present invention will be described in detail.

First, the RF plasma multi-air sterilization device according to the present invention is a pre-treatment sterilization module (30) that largely sucks in external air and generates a first mixed gas (c1) by mixing single molecule water molecules and ion-radical substances. And, a post-treatment sterilization module (40) that receives the first mixed gas (c1) from the pre-treatment sterilization module (30) and mixes single-molecule water molecules and ion-radical substances to generate a second mixed gas (c2). ) and a control module 50 that controls the output amount (supply amount) of moisture and RF energy consisting of water vapor or wet steam supplied to these pre-treatment sterilization modules 30 and post-treatment sterilization modules 40.

The pretreatment sterilization module 30 includes a first body 31 forming an outer body, a first reaction chamber 33 provided in the form of a double pipe to have a relatively reduced diameter inside the first body 31, and A first moisture supplier 35 installed on one side of the first reaction chamber 33 to supply moisture in the form of water vapor or wet steam into the second reaction chamber 33, and the first reaction chamber 33 ), which converts water in the form of water vapor or wet vapor supplied into the inside of the device into single-molecule water molecules through a dielectric heating effect, and also generates ion-radical substances through a plasma discharge phenomenon using RF energy. It consists of a feeder (37).

The first body 31 forms the entire outer body of the pre-treatment sterilization module 30, and has a space inside where the first reaction chamber 33 can be installed, and has a space on one side for sucking in external air. One intake port (31a) is provided, and a first discharge port (31b) is formed on the other side to discharge the internal air to the outside. This first body 31 is provided in a cylindrical shape with a sealed structure.

In addition, the first intake port 31a is configured to be equipped with a filtration filter 32 to filter out foreign substances, including floating substances, contained in the air flowing in from the outside.

The first reaction chamber 33 is disposed inside the first body 31 and is provided as a hollow tube-shaped member with a relatively reduced diameter, shielded at both ends and spaced at equal intervals on the outer surface. A plurality of first discharge holes 33a are formed through. This first reaction chamber 33 is configured to receive wet steam/water vapor (a), which is moisture in the form of a cluster, and RF energy from a first moisture supplier 35 and a first RF supplier 37, which will be described later, on one side, respectively.

In addition, the first reaction chamber 33 in the present invention may be made of a metal material or a known electromagnetic wave shielding structure to prevent leakage of the RF energy irradiated inside, and in addition, the first reaction chamber 33 may be installed inside the first reaction chamber 33. A heat generating heater that receives power to increase the temperature of the supplied moisture and generates heat may be additionally provided inside or outside. In this case, the heat generating heater is used for dielectric heating by the first RF supply 37, which will be described later, during the heating process. Instead, it serves to raise the temperature to a certain level through heater heating.

Meanwhile, the first reaction chamber 33 allows ultrafine water droplets (b) composed of single-molecule water molecules and ion-radical substances discharged through the first discharge hole (33a) to enter the inside of the first body (31). It is desirable to form a spiral-shaped vortex fin (not shown) on the outer surface or to form a plurality of first discharge holes (33a) arranged in the direction of the screw so that it can be easily mixed with the external air by forming a vortex when discharged. do.

The first moisture supplier 35 is installed on one side of the outside of the first reaction chamber 33 and is an element for supplying cluster-shaped moisture in the form of water vapor or wet steam to the inside of the first reaction chamber 33. . This first moisture supplier 35 can be largely used as 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. These ultrasonic oscillators and a heated evaporator are used by known technologies. This is okay, so detailed description will be omitted. In addition, the first moisture supplier 35 may be a nozzle sprayer for spraying high-pressure water through a nozzle, or a natural vaporization type evaporator may be used, and in addition, it has the technical feature of supplying moisture in small particles. It would 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 first RF supplier 37, which will be described later, becomes easy.

The first moisture supplier 35 configured as described above is configured to supply cluster water droplets in the form of water vapor or wet steam to the inside of the first reaction chamber 33, and the moisture in the form of clusters supplied in this way is supplied to the first RF supplier to be described later. (37) It is dielectrically heated by the RF energy supplied and converted into unit water molecules, and ion-radical substances are generated by the plasma discharge phenomenon caused by the RF energy.

The first RF supplier 37 is installed on one side of the first reaction chamber 33 and supplies (output) RF energy with an output of 0.1 kw to 1 MW to the inside of the first reaction chamber 33. ), thereby converting the cluster water droplets in the form of water vapor or wet vapor supplied through the first moisture supplier 35 into unit water molecules, which are fine water droplets, through a dielectric heating effect, and also unit water molecules due to plasma discharge by RF energy. Hydrogen ions, hydroxyl ions, hydrogen radicals, and hydroxyl radicals are generated.

When one or more of the first RF feeders 37 are installed, it is preferable that they are configured to operate sequentially. This is because durability drops drastically when the first RF feeders 37 are continuously operated.

The post-treatment sterilization module 40 has a very similar configuration to the pre-treatment sterilization module 30 described above. However, the post-treatment sterilization module 40 receives the first mixed gas (c1) generated in the pre-treatment sterilization module 30 and generates ultrafine water droplets (b) composed of ion-radical substances and single-molecule water droplets.
