The problem of the indoor environment can be said to be a problem caused by indoor pollution, that is, various pollutants generated by human activities are released into the room and pollute the indoor environment.

Various contaminants can be present in indoor air, physically, chemically and biologically. Since these pollutants are caused by complex emission sources such as inflow of outside air, cigarette smoke, heaters, ovens, cookware, cement, detergents, building materials, paints, etc., their emissions are also known to show considerable variation depending on pollutants.

For example, as a result of measuring and analyzing the indoor air quality of a department store located in Seoul, carbon dioxide (CO ₂ ) 779 PPM, nitrogen dioxide (NO ₂ ) 40 PPM, formaldehyde (HCHO) 0.16 PPB, total suspended dust ( TSP) was 0.023 μg/m3, and microorganisms were found to be high at 297 CFu/m3 for fungi and 1622 CFu/m3 for total bacteria. In addition, it has been investigated that process gases are introduced into the offices of industrial plants, and various odorous harmful substances such as ammonia (NH ₃ ), hydrogen sulfide (H ₂ S), and benzene (C ₆ H ₆ ) are introduced to cause health disorders. became

The indoor pollutants as described above are adsorbed into the fibrous pores of the occupant's clothes, causing discomfort and acting as a nutrient for bacteria, thereby adversely affecting the health of the occupant.

In addition, since December 1, 2019, COVID-19 has spread around the world, and the World Health Organization (WHO) declared a public health emergency of international concern on January 31, 2020, and as of February 28, COVID-19 has been declared an epidemic.

However, in most restaurants and shopping malls, facilities or devices for removing indoor pollutants or preventing indoor pollutants from adsorbing to the fibrous pores of occupants' clothes are not provided.

In addition, in the conventional pharmaceutical manufacturing process, semiconductor manufacturing process, precision operating room, etc., an air shower device using a filter is provided. There is an air shower device that can deodorize and sterilize bacteria using The effect on sterilization of bacteria is insufficient, and there is no bactericidal effect of viruses by these filters.

For example, in the Republic of Korea Patent Registration No. 10-1956143 (Title of the invention: air shower gate), it is installed at the indoor and outdoor entrances to remove fine dust or harmful substances and napkins attached to people entering and exit, and to monitor indoor and outdoor air quality. To maintain and manage a pleasant and clean indoor environment through air cleaning or ventilation, it removes dust on clothes due to going out, etc. , Performs a cleaning function by filtering indoor air, filters outdoor air according to sensor information, and introduces it into the room for ventilation ,Since the side spray angle is inclined downward, clothing such as skirts do not fluctuate up and down. It has no vibration suppression function, sterilization function of bacteria and viruses in floating air, and no function of wiping and irradiating both edges.

Republic of Korea Patent Registration Publication No. 10-1565952 (Air shower device with disinfectant spray function) Clean air from which foreign substances have been removed through the main filter installed in the body is sprayed at high speed through the air jet nozzle, and foreign substances attached to the body or articles An air shower booth that removes contamination, a blower that sucks in the air inside and supplies and circulates the sucked air back into the air shower booth, and a disinfectant solution tank that stores the disinfectant solution sprayed into the air shower booth and a pump that pumps the disinfectant solution stored in the disinfectant solution storage tank In the process of sterilizing the internal space, articles, and the human body by spraying it into the air shower using a pipe and a spray nozzle, this technology controls the It is consumed and the maintenance cost increases, and there is no quantum energy generation and irradiation function.

In the Republic of Korea Patent Registration No. 10-1565950 (air shower device with filter replacement alarm function for preventing secondary pollution), clean air is injected at high speed through the jet nozzle to remove foreign substances attached to the body or articles, and During the process of sucking air inside the air shower booth using a blower, the main filter with a filter contamination level measuring sensor connected to the MCU on one side of the filter on the elastic member is tilted and grounded by the suction force of the blower, and the filter contamination level is transmitted to the MCU and This is an air shower device that includes a filter replacement list function to prevent secondary contamination of the filter by sounding a warning sound or flickering an alarm when the filter contamination level measuring sensor is grounded while the blower is not operating due to a mechanical defect. There is no sterilization function of medium bacteria and viruses, and there is no quantum energy emission and irradiation function.

In conclusion, since the conventional air shower device is an air purification device that mainly removes dust, there is a problem that not only cannot remove harmful indoor pollutants, but also deodorization and sterilization effects such as coronavirus-19 are very insufficient.

2) e + N2 → N2+ + 2e

3) e + O2 → O + O+ + 2e

* e is the high electric field electron energy applied to ozone and nitrogen molecules during arc discharge

In addition, in the electrochemical reaction process, the OH radical active species generation reaction that sterilizes bacteria and viruses in the air consists of the following steps for dissociating and generating water molecules of water vapor in the air.

1) e + H2O → H+ + OH-

2) e + H2O → H + OH + e

3) O + H2O → 2OH-

As described above, oxygen active species (ROS) such as oxygen ions (O), singlet oxygen (102), and hydroxyl ions (OH-Radical) generated by dissociation of water molecules are introduced into the corona 19 virus in clean air, It sterilizes or sterilizes by perforating the biofilm of bacteria such as MERS virus, SARS virus, Ebola virus, and bacteria to damage internal organs and outflow them.

In addition, the pollutant gas flowing into the arc discharge unit 200 is disposed between the trigger electrode 210a and the ground electrode 210b of the arc discharge device 210 to which a variable AC power in the form of a pulsed electromagnetic field (PEMF) is applied. As it passes through the arc discharge zone, it is converted to an excited state by high-energy electrons to decompose pollutants in the polluting gas, and the biofilms of bacteria and airborne viruses suspended in the air by active oxygen and OH radicals are perforated, causing damage and leakage of organs Bacteria are strongly sterilized. Specifically, the high energy generated by the arc discharge from the arc discharge electrode of the arc discharger 210 is applied to the electrochemical reaction such as dissociation, excitation, ionization, oxidation, and reduction reaction of air constituent molecules and pollutant gases contained in the air. In the dissociation process, arc active molecules such as active oxygen, active nitrogen, hydrogen atom, CH3 radical, and OH radical, which have very strong oxidizing power, are generated. It is to be easily (efficiently) converted into a compound harmless to the human body by primary oxidation in proportion to the

The voltage applied to the trigger electrode 210a and the ground electrode 210b from the power supply 230 of the arc discharge unit 200 is a field electron energy (IE, eV) capable of decomposing the covalent bond of oxygen (O2) molecules. ); When a high voltage of 12.0857 eV or higher is not applied, oxygen molecules (O2) are partially dissociated as shown in Equation 1 to generate ozone.

Conversely, the voltage applied to the trigger electrode 210a and the ground electrode 210b from the power supply 230 applies electric field energy (IE, eV) capable of decomposing the covalent bond of oxygen (O2) molecules; a high voltage of 12.0857 eV or more is applied. As shown in Equation 2, ozone (O3) is completely dissociated into oxygen atoms (O) and oxygen molecules (O2).

e + O3 → O + O2 -------------------- Equation 2

In addition, since the surface temperature of the discharge point is maintained at a high temperature in the range of 6000°C to 10000°C during discharge from the trigger electrode 210a and the ground electrode 210b, ozone (O3) in contact with this high-temperature surface is thermally decomposed as shown in Equation 3 It dissociates into oxygen atoms (O) and oxygen molecules (O2).

O3 + heat (T) → O + O2 -------------------- Equation 3

In addition, during discharge from the trigger electrode 210a and the ground electrode 210b, nitrogen molecules (N2) are dissociated into nitrogen atoms (N), and ozone (O3) reacts with the dissociated nitrogen atoms (N) to generate oxygen as shown in Equation 4 It dissociates to form molecules (O2) and nitric oxide (NO).

O3 + N → O2 + NO -------------------- Equation 4

In addition, the pulsating quantum energy generator surrounding the outside of the arc discharge unit includes the pulsed variable power supply 410 , a first cusp coil 420 , a second cusp coil 430 , and a permanent magnet 440 . Power is supplied from the pulsed variable power supply 410 to the first cusp coil 420 and the second cusp coil 430 of the pulsating quantum energy generator 400 and the pulsed electromagnetic generated by the superimposition of the zero magnetic field state The arc discharge efficiency (density) is improved by irradiating the pulsating quantum energy generated in the permanent magnet 440 and the magnetic force line emitted from the N pole of the permanent magnet 440, and electrons and active species (oxygen ions, nitrogen ions, By extending the lifespan of radicals), it improves the removal rate of odor-causing substances, the sterilization rate of bacteria and viruses in the suspended air, and the ozone decomposition rate.

However, as described above, the arc active molecules generated by the arc discharge of the arc discharger 210 oxidize the pollutants while in direct contact with the pollutants of the polluting gas, and in the process of converting the pollutants into compounds harmless to the human body, electromagnetic waves harmful to the human body, 85˜88 decibels of noise, ozone and static electricity are inevitable. Unless these electromagnetic waves, noise, ozone and static electricity are significantly reduced or removed, it is very difficult to use them as an air shower device for indoor use.

Although the electromagnetic wave generated by the arc discharge of the arc discharger 210 has a function of accelerating the decomposition of contaminants contained in the polluting gas to some extent, there is a problem in that it is very harmful to the human body. Accordingly, an electromagnetic wave shielding layer 211 made of an electromagnetic wave shielding material is formed on the inner circumferential surface of the arc discharge support tube 220 accommodating the arc discharger 210 to shield electromagnetic waves generated by arc discharge of the arc discharger 210 . The electromagnetic wave shielding material that shields electromagnetic waves generated by electronic devices is divided into a reflective electromagnetic wave shielding material that is made of a conductive material and has a function of reflecting electromagnetic waves, or an absorption type electromagnetic wave shielding material that is made of a semiconducting material and has a function of absorbing electromagnetic waves. In the present invention, a reflective electromagnetic wave shielding material having a function of reflecting electromagnetic waves is used to form an electromagnetic wave shielding layer 211 that reflects electromagnetic waves on the inner circumferential surface of the arc discharge support tube 220 by arc discharge of the arc discharger 210. It is preferable in terms of reflecting the generated electromagnetic waves and blocking the leakage to the outside of the arc discharge unit 200, and at the same time, the reflected electromagnetic waves can promote decomposition of contaminants.

Specifically, at least one selected from the group consisting of conductive carbon, soft ferrite, and carbon fiber nonwoven fabric having excellent electromagnetic wave reflection and shielding function and flexibility on the inner circumferential surface of the arc discharge support tube 220 of the arc discharge unit 200 The reflective electromagnetic wave shielding material is included to form the electromagnetic wave shielding layer 211 of a certain thickness. The electromagnetic wave shielding layer 211 formed on the inner circumferential surface of the arc discharge support tube 220 reflects the electromagnetic waves generated by the arc discharge of the arc discharger 210 and blocks the leakage to the outside of the arc discharge unit 200, thereby adversely affecting the human body. At the same time, the reflected electromagnetic wave promotes decomposition of contaminants inside the arc discharge unit 200, thereby improving the removal efficiency of contaminants.

In addition, polyurethane foam, synthetic resin impregnated nonwoven fabric, microporous ceramic, etc. on the outer circumferential surface of the arc discharge support tube 220 to reduce the noise of 85˜88 decibel generated by the arc discharge of the arc discharger 210 is known. The sound absorbing material layer 222 made of the sound absorbing material is formed to absorb the noise generated by the arc discharge of the arc discharger 210 and block the leakage to the outside of the arc discharge unit 200 .
