Description

Plasma continuous supply type air sterilizer using RF electromagnetic wave energy}

The present invention relates to a plasma continuous supply type air sterilization device using RF electromagnetic wave energy, and more particularly, by irradiating RF electromagnetic wave energy to moisture in the form of clusters of water vapor or wet steam, cluster through dielectric heating and plasma discharge action. In addition to converting water in the form of water into unit water molecules, in this process, ion and radical substances composed of hydrogen ions, hydroxyl ions, hydrogen radicals, and hydroxyl radicals are generated to improve indoor air quality through sterilization of viruses and pathogens in the air. It relates to a plasma continuous supply type air sterilization device using RF electromagnetic wave energy to promote

Recently, interest in indoor air quality has increased as living time indoors and activity time in indoor spaces increase. Looking at the causes of indoor air pollution, it is largely caused by inflow from the outside into the room or by residents' indoor activities. It can be seen as a case that is generated by itself, and if you look at the pollutants flowing into the room from the outside air, there are various pollutants including fine dust, various air pollutants generated from vehicle operation and industrial sites, including fine dust, and generated from the indoor air itself. Looking at pollutants that are pollutants, radon and asbestos generated from building materials, kitchen heating fuel, residents' daily activities and various household items, and formaldehyde, dust, and volatile organic compounds generated from various household items, etc. (VOC), as well as nitrogen dioxide, carbon monoxide, cigarette smoke, and microorganisms.

Since these pollutants are known to cause various diseases including respiratory diseases, various technologies for improving indoor air quality have been proposed to efficiently remove pollutants to create a pleasant indoor environment. There are wet air purifiers.

The dry-type air purifier sucks polluted air with a fan and then forcibly passes it through a filter so that dust or bacteria are filtered out in this process. It is configured to filter out, and if the period of use is long, it may become a source of pollution due to contamination of the filter, so it must be replaced periodically.

In addition, the 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 such as droplet liquid film bubbles generated by spraying water into the inhaled air. This method is Compared to the dry method, it does not use a separate filter, so there is an advantage that there is no need for replacement. However, if the water is not changed frequently, contamination by bacterial propagation and relatively large particle contaminants can only 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 that pose a direct and fatal threat to human health can cause transmission between humans. It is made of protein and has high propagation power, and mutations occur easily, and it takes a lot of time to develop a cure.

On the other hand, various pollutants including viruses contained in the air are known to cause various diseases including respiratory diseases. Several technologies have been proposed to improve indoor air quality so that pollutants can be efficiently removed to create a pleasant indoor environment. There are dry type and wet type air purifiers.

A dry-type air purifier sucks polluted air through a fan and then forcibly passes it through a filter so that dust or germs are filtered out in this process. It is structured to take out. Here, the filter is a high-density filter with a dust collection efficiency of 80% to 99.97% for a particle of 0.3, and is efficient in collecting small particles. As the air volume increases, the air volume decreases and the purification capacity decreases. Therefore, the economic burden due to periodic filter replacement and disposal is great, and it is difficult to treat contaminants such as viruses or bacteria with only the filtration method.

The wet-type air purifier is a method in which dust particles suspended in the air come into contact with liquid film bubbles generated by injecting water into the inhaled air to remove dust particles through inertial collision direct absorption and diffusion. This method is a dry method. Compared to , it does not use a separate filter, so it has the advantage of not requiring replacement, but if the water is not changed frequently, contamination by bacterial propagation and relatively large particle contaminants can only be treated, so the dust collection efficiency for fine dust is low. It is not widely used due to its drawbacks.

On the other hand, in recent years, an anion generating device has been additionally configured to neutralize polluted dust or positive ions having a positive charge in the dry type air purifier. there is

In addition, a device that promotes sterilization using ultraviolet rays by additionally installing an ultraviolet (UV) lamp has been proposed, but actions such as sterilization and deodorization of pollutants can be achieved only after a certain contact time at a certain distance (eg, within about 20 cm) from the ultraviolet light source. Therefore, adequate effect can be obtained only when sufficient air is introduced into the device, and the effect is limited depending on the degree of contamination or life limit of the lamp used as the light source. In addition, there is a disadvantage in that pollutants attached to the inside of the facility, not floating pollutants in the air, cannot be removed.

In addition, there are air purifiers with an ozone generator installed. However, ozone sterilization uses ozone made by ionizing air or oxygen, which is effective in removing pollutants attached to the air as well as pollutants in the air. Although it is suitable for facilities handling types of products, supplementary devices for effective removal of pollutants frequently occurring in the living environment are insufficient in addition to the problem of indoor residence safety when ozone is used. In the case of general air sterilizers, the standard is 0.05ppm or less. According to what is generally known in the food science field, when the ozone concentration is at least 0.5ppm, the death rate is over 99.9% in a few seconds to several minutes. The sterilizing power of ozone or active species at a concentration below is inevitably limited.

As such, in the case of an air purifier using a plasma generator, an ozone generator, and an ultraviolet lamp according to the prior art, the sterilizing power should be stably maintained in the case of a facility in which the attachment and proliferation rate of microorganisms floating in the air are considered or frequent pollutants are introduced. Realistically, in the case of ozone or plasma, the reaction time is less than a few seconds, and as it is created and destroyed at the same time, there is a limit to increasing the removal efficiency of microorganisms such as airborne bacteria in indoor air. In the case of adhering to the surface of a product or the like to become adherent bacteria, there is a disadvantage in that it is impossible to remove such contaminants.

That is, the air purifier according to the prior art simply sucks in indoor air and passes it through a high-density filter such as a HEPA filter to filter out pollutants, thereby removing dust or foreign matter to reduce the degree of indoor pollution. 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. I had this difficult problem.

As another prior art, a 'nano bubble generator and a nano bubble generator' have been proposed through Korean Patent Publication No. 20-2019-0042081, and claim 1 includes a 'housing; at least one blade; at least one second magnet; and at least one second magnet, wherein the housing includes: an inlet for receiving a liquid containing macro bubbles; a second chamber operably disposed downstream of the inlet; a second chamber operably disposed downstream of the second chamber; and an outlet operably disposed downstream of the second chamber, wherein the at least one blade is positioned within the second chamber and, in use, contains micro bubbles in a liquid for converting such macro bubbles into micro bubbles. cutting; the at least one second magnet is positioned within the second chamber; the at least one second magnet is associated with the second chamber, (i) the at least one second magnet and the at least one second magnet, wherein the polarity of the at least one second magnet is that of the at least one second magnet; It is arranged so that the polarity is reversed, and (ii) at least one second magnet is movable with respect to the at least one second magnet.' A nano bubble generator has been proposed.

However, the nanobubble generator according to the prior art is a technique of physically cutting microbubbles using a blade, and has limitations in splitting water droplets with a large unit surface area in which a large number of water molecules are clustered, especially in the form of single molecules. There was a flaw that was impossible to process.

As another prior art, an air purifying device using streamer discharge has been proposed through Korean Patent Publication No. 20-2006-0085647, but radicals are generated by streamer discharge, and sterilization by diffusion of the radicals There is a problem in that it is difficult to improve the sterilization performance by performing the treatment, and since the discharge intensity must be increased to improve the sterilization treatment performance, there is a problem in that a large amount of ozone is generated beyond a prescribed value.

In addition, in order to improve the sterilization treatment performance by radicals, a catalytic means is required, and as such a catalytic means is disposed in a direction perpendicular to the air flow path on the discharge port side, it obstructs the air flow to increase the differential pressure, and There is a problem in that the structure of the discharge unit obstructs the flow of air and increases differential pressure. In addition, there are restrictions on the shape of the discharge unit, and accordingly, there is a problem in that it is difficult to apply to air cleaners of various shapes.

Therefore, there is an urgent need for technology development capable of safely and quickly removing and sterilizing pathogens such as bacteria and fungi, as well as various contaminants in the air.

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

1 is a conceptual diagram illustrating a process of converting water (clustered water molecules) clustered by hydrogen bonding between water molecules according to the present invention into unimolecular water molecules by RF dielectric heating.

The figure is a conceptual diagram for explaining a process in which cluster-type water molecules 10 constituting water are converted into single-molecular water molecules 20 by RF dielectric heating. Oxygen, which makes up water molecules, has a certain portion of electronegativity due to relatively strong electron affinity, so it has a weak negative charge (δ ^- ), and hydrogen, which makes up water molecules, has relatively weak electrons. It has a weak electronegativity due to affinity, so it has a weak positive charge (δ ⁺ ).

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

2 is a conceptual diagram illustrating the conversion of water (cluster-type water molecules) into single-molecular 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 electromagnetic wave energy is irradiated, a plasma discharge phenomenon occurs. Since the water molecules 20 are ultra-fine water droplets and have very excellent chemical reactivity, a chemical reaction is effected quickly, and since water is formed as a by-product, damage from environmental pollution can be reduced.

3 is a schematic diagram of a chemical reaction scheme for the conversion of moisture (water molecules in cluster form) in a water vapor or wet vapor state into single molecular water molecules by RF dielectric heating according to the present invention. An example in which a unit cluster composed of n water molecules is converted into n single-molecular water molecules by RF dielectric heating is shown.

4 is a schematic diagram illustrating a chemical reaction formula of ultra-fine water droplets as an example according to the present invention. As an example of the chemical decomposition of toluene or chloroform, which is one of the environmentally harmful substances, it shows the process of decomposition by meeting water molecules in the form of single molecules with excellent chemical reactivity.

6 is a conceptual diagram of measuring the concentration of ultra-fine 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 (δ ⁺ ) of hydrogen and the negative charge (2δ ^- ) of oxygen. When these dielectric molecules measure the voltage applied to the two electrode plates, the difference in voltage measured when the water molecules in the form of a cluster 10 and the water molecules in the form of a single molecule 1 constituting a cluster occurs, It is possible to measure the concentration of water molecules in molecular form.

With reference to the above drawings, the configuration of the plasma continuous supply type air sterilization device using RF electromagnetic wave energy according to the present invention will be described in detail.

First, the plasma continuous supply type air sterilization device using RF electromagnetic wave energy according to the present invention forms a large outer body and has a main body 100 provided with a passage for sucking and discharging external air inside ( 200), a plasma generating module 30, and a control module 50.

The main body 200 forms an overall outer body, and includes a suction port 211 for inhaling air from the outside, an outlet 213 for discharging the sucked air after mixing it with a chemical reactant, and the suction port 211. It consists of a case 210 having a main conduit 100, which is a passage connecting the outlet 213 and the outlet 213.

The inlet 211 is provided on the lower front side of the main body 200 to suck in air from the outside, and may be provided in a mesh or grill shape. This inlet 211 is provided so that the user can separate it, and a filter 215 for filtering out suspended matter or contaminants in the air that is sucked into it is exchangeably provided, which is a known configuration. Since it may be implemented by technology, a detailed description thereof will be omitted.

The discharge port 213 is provided on the front upper side of the case 210 to discharge process air mixed with chemical reactants generated in the plasma generation module 30 to be described later while passing through the main conduit 100. is an element The discharge port 213 may be configured with a guide pin for adjusting the amount of air discharged or the direction of the air, and since this is performed by a known technique, a detailed description thereof will be omitted.

The main conduit 100 is a passage connecting the inlet 211 and the outlet 213, and a plasma generating module 30 to be described later is configured therein. The main conduit 100 is an element that provides a space in which pollutants contained in the air can be removed by mixing chemical treatment substances generated in the plasma generating module 30 with air sucked in from the outside.

On the other hand, on one side of the inside of the case 210, while connected to the main conduit 100, air is forcibly sucked in through the inlet 211 and blown to be discharged through the outlet 213 via the plasma generating module 30. A blowing fan 217 that acts is configured.

A plurality of plasma generating modules 30 are installed at intervals in the main conduit 100 and continuously generate chemical reactants composed of water molecules in the form of single molecules and ions and radicals by RF electromagnetic wave energy excitation. , The reaction chamber 33 forming an external body by being circuit-connected to receive a control signal from the control module 50 to be described later and operate so that the chemical reactant can be continuously supplied to the inner space of the main conduit 100, and the reaction It consists of one or more RF suppliers 37 installed in the chamber 33 and a water supply unit 35 for supplying water droplets in cluster units in the form of steam or wet steam.

The reaction chamber 33 is for supplying chemical reactants generated by the RF supplier 37 and the water supplier 35 to the inner space of the main conduit 100, which will be described later, and has an empty interior. , A configuration in which a plurality of discharge holes (unsigned) are formed through to discharge chemical reactants generated inside on one side of the outside.

That is, the reaction chamber 33 in the present invention is arranged and configured to supply the chemical reactant (c) to the inside of the main conduit 100, and is provided as a hollow tubular member having a relatively reduced diameter. Both ends are shielded, and a plurality of discharge holes (unsigned) are formed through one outer surface at equal intervals. The reaction chamber 33 is configured to receive moisture in the form of wet steam/water vapor in a cluster form and RF electromagnetic wave energy from a water supply unit 35 and an RF supply unit 37, which will be described later, on one side, respectively. In addition, the reaction chamber 33 in the present invention may be applied with a metal material or a known electromagnetic wave shielding structure so that the RF electromagnetic wave energy irradiated therein does not leak. In addition, the reaction chamber 33 is supplied with moisture An exothermic heater that generates heat by receiving power to increase the temperature of may be provided on the inside or outside, and the exothermic heater at this time is heated during the heating process, not by dielectric heating by the RF supply 37, which will be described later. It serves to raise the temperature to a certain level.

On the other hand, the reaction chamber 33 is configured to form a vortex when ultrafine water droplets composed of monomolecular water molecules and ion ㅇ radical substances discharged through the discharge hole 33a are discharged to the inside of the main conduit 100 By doing so, it will be possible to form a spiral vortex fin (not shown) on the outer surface so that it can be easily mixed with external air, or to arrange a plurality of discharge holes in a spiral direction.

In addition, the reaction chamber 33 in the present invention is a shield door that selectively shields the inner space of the reaction chamber 33 by selectively opening and closing the discharge hole, and is connected to the shield door to perform an opening and closing operation. A configuration including an opening/closing driving source providing a driving force is preferable, and in one embodiment, it is provided in a form surrounding the reaction chamber 33 and is directed to one side by the opening/closing driving source in a state in which a through hole corresponding to the discharge hole is formed. It will be provided in the form of sliding to open the plurality of discharge holes or sliding to the other side to close the plurality of discharge holes, and the shielding structure of these discharge holes may be variously implemented by known technology, so detailed omit explanation. However, the reason why the configuration of opening and closing the discharge hole in the present invention is proposed is that in a state in which the inner space of the reaction chamber 33 is closed, RF electromagnetic wave energy is supplied together with moisture in the form of steam or wet steam, so that dielectric heating and plasma discharge are easy. This is to ensure that the chemical reaction material is discharged into the main conduit 100 by opening the discharge hole when a chemical reaction material is generated by the moisture and RF electromagnetic wave energy.

The moisture supplier 35 is an element installed on one side of the reaction chamber 33 to supply moisture in cluster units in the form of steam or wet steam to the inside.

That is, the moisture supplier 35 in the present invention is installed on one side of the outside of the reaction chamber 33 and is an element for supplying moisture in the form of water vapor or wet steam to the inside of the reaction chamber 33.

The water supply device 35 may be a water tank and an ultrasonic oscillator or heating evaporator that receives water from the water tank and converts it into water vapor. Since it may be implemented, a detailed description is omitted. In addition, the water supplier 35 may be a nozzle sprayer for spraying high-pressure water through a nozzle or a natural evaporation type evaporator. It will also be possible to apply various techniques of .

To explain further, the water supply device 35 in the present invention proposes to use any one or a combination of an ultrasonic oscillator, a heating evaporator, a steam enhancer, and a nozzle sprayer that can generate a large amount of water vapor. The temperature is 50 to 150 ° C, which is higher than room temperature, because when a high-temperature moisture cluster is supplied, conversion into unit water molecules by dielectric heating by the RF supplier 37, which will be described later, becomes easy. .

The moisture supplier 35 configured as described above is configured to supply cluster water droplets in the form of steam or wet steam to the inside of the reaction chamber 33, and the supplied moisture in the form of clusters is supplied from the RF supplier 37 to be described later. It is dielectrically heated by the RF electromagnetic wave energy and converted into unit water molecules, and also generates ions and radicals by the plasma discharge phenomenon by the RF electromagnetic wave energy.

The RF supplier 37 supplies RF electromagnetic wave energy to the inside of the reaction chamber 33 to generate water vapor supplied by the water supplier 35 in units of cluster units or water droplets in the form of wet steam through dielectric heating of water droplets.
