Description

Indoor air sterilization and purification device {INDOOR AIR STERILIZATION AND PURIFICATION EQUIPMENT}

The present invention relates to indoor air sterilization and purification devices.

The Central Disaster and Safety Countermeasures Headquarters urges all citizens to practice strengthened 'social distancing' for the next 15 days to suppress the spread of COVID-19 and transition to 'life quarantine' where daily life and quarantine measures can be harmonized. They appealed for their participation.

Social distancing has been shown to be effective in blocking the spread of COVID-19, and thanks to our people's voluntary participation in social distancing based on mature civic consciousness, our country has been able to prevent the rapid mass spread of COVID-19 to some extent.

However, experts say that community infections are spreading, with group infections recently occurring centering on religious facilities and workplaces and the number of confirmed cases stagnating at around 100. COVID-19 infections are rapidly spreading globally, so domestic infections can occur at any time. Considering that the COVID-19 epidemic may be reintroduced, the opinion is that social distancing must be continuously practiced under the recognition that the COVID-19 epidemic will be prolonged and that it is not a safe situation.

However, as social distancing continues for three weeks, fatigue across society is increasing and people's participation is weakening, and the need to find ways to implement sustainable social distancing that can achieve a certain level of harmony with daily life is also increasing.

Considering these issues, health authorities will first focus on short-term enhanced social distancing to reduce community infections to a level that the current quarantine and health care system can handle, and based on this, social distancing will be implemented to prevent a long-term epidemic. In preparation for this, a plan has been established to transition to a daily quarantine system that harmonizes daily life and economic activities.

Accordingly, considering the incubation period (14 days) of COVID-19, intensive social distancing for 15 days has been implemented to achieve the effect of early detection or natural cure of infected patients who may exist in the community without secondary transmission. An attempt is made to reduce the level of risk.

However, no matter how well the daily quarantine system is implemented for asymptomatic infections, there are limitations in the living environment in which humans live.

Referring to Figure 1, according to an embodiment of the present invention, indoor air containing the causative agent of viral infection in the "aerosol" state by droplets (salivary droplets) is sucked in to remove coronavirus, various bacteria, ultrafine dust, and droplets ( By eliminating causes of transmission and infection such as saliva droplets, reproducing and supplying clean and clean air, we prevent the spread of various infectious agents such as novel coronavirus infection (hereinafter referred to as COVID-19) and group infection in multi-use facilities.

Referring to Figure 2, the indoor air sterilization and purification device of the present invention sterilizes and purifies indoor air contaminated by viruses, bacteria, ultrafine dust, droplets, etc., the indoor air sterilization and purification device of the present invention has a body. A case 100 forming a case 100, a blowing fan 200 coupled to the upper part of the case 100 to introduce and discharge air from the outside into the inside of the case 100, and a sterilization chamber containing air and sterilizing water introduced from the outside. (300), a sterilizing water tank 400 that accommodates the firstly purified second sterilizing water, an electrolysis device (500: ELECTROLYSIS DEVICE) accommodated in the sterilizing water tank 400, and firstly purified air It includes a sterilizing device 600 that secondarily purifies the air, and a filter member 700 that thirdly purifies the air secondaryly purified by the sterilizing device 600.

The case 100 forms the body of the indoor air sterilization and purification device according to an embodiment of the present invention, and has a sterilization chamber 300, a sterilization water tank 400, an electrolysis device 500, and a sterilization device ( 600), etc., various configurations are accepted.

At the top of this case 100, an inlet 120 is formed on one side of which the first fan member 210 of the blowing fan 200 is coupled, and on the other side, the second fan member 220 of the blowing fan 200 is formed. A combined outlet 130 is formed.

That is, contaminated air from the outside flows in through the first fan member 210 of the blowing fan 200 coupled to the inlet 120 on one side of the case 100, and the air purified from the inside of the case 100 is discharged through the second fan member 220 of the blowing fan 200 coupled to the outlet 130 on the other side of the case 100.

The directions of the inlet 120 and outlet 130 formed on one side and the other side of the case 100, respectively, may change depending on the indoor environment in which the case 100 is placed.

Additionally, a partition wall 110 extending downward from the center is formed on the upper surface of the case 100.

The partition wall 110 divides the interior of the housing 310 into one direction and the other direction.

In addition, the sterilization chamber 300 is disposed in one direction, which is the direction in which the inlet 120 is formed around the partition wall 110, and the sterilization device 600 is disposed in the other direction, which is the direction in which the outlet 130 is formed around the partition wall 110. ) and filler members are placed.

The blowing fan 200 is coupled to the inlet 120 and outlet 130 of the case 100, and rotates when power is applied from the outside.

This blowing fan 200 includes a first fan member 210 and a second fan member 220.

The first fan member 210 is coupled to the inlet 120 of the case 100, and the rotating first fan member 210 is used in indoor areas contaminated with viruses, bacteria, ultrafine dust, droplets, etc. Air is continuously sucked in and moved to the sterilization chamber 300 placed inside the case 100.

The second fan member 220 is coupled to the outlet 130 of the case 100, and the rotating second fan member 220 is introduced by the first fan member 210 and purifies the inside of the case 100. Discharge the accumulated air to the outside.

The sterilization chamber 300 is disposed below the first fan member 210 inside the case 100.

That is, the sterilization chamber 300 is disposed in an area centered on the partition wall 110 in the direction in which the inlet 120 is located.

Additionally, air sucked from the outside is introduced into the sterilization chamber 300 through the first fan member 210 coupled to the inlet 120.

This sterilization chamber 300 includes a housing 310, a spray nozzle 320, a triangular plate member 330, and a mixing generator 340.

Referring to Figures 2 and 3, the housing 310 forms the body of the sterilization chamber 300 and is disposed below the first fan member 210 inside the case 100.

Additionally, the middle area of the housing 310 is comprised of a narrower passage than the upper and lower areas and has an overall venturi shape.

Due to this, the housing 310 can lower the internal pressure of the sterilization chamber 300 into which the first sterilizing water for sterilizing the contaminated air is sprayed by the so-called Venturi effect according to Bernoulli's law, and the inside of the housing 310 By increasing the flow rate of the first sterilizing water and air sprayed, the sterilizing water of the contaminated air can be effectively mixed.

Meanwhile, the above-mentioned first sterilizing water is made of HOCL, and HOCL can be defined as hypochlorous acid (HYPOCHLOROUS ACID), oxygen-rich water with many + ions, active oxygen water, etc.

Referring to FIGS. 2 and 4 , the spray nozzles 320 are comprised of a plurality of spray nozzles 320 and are coupled to each other at the top of the housing 310 to communicate with each other inside the housing 310 .

Then, the spray nozzle 320 sprays the fine first sterilizing water from the outside into the inside of the housing 310 at high speed.

This lowers the internal pressure of each guide member 360 by the so-called Bernoulli's law, thereby increasing the overall suction power.

That is, inside the sterilization chamber 300, the contaminated air is easily sucked into the guide member 360 and the housing 310 by the first fan member 210, and the sucked contaminated air is sucked into the spray nozzle. It is mixed with the first sterilizing water sprayed through (320), and viruses, various bacteria, ultra-fine dust, and droplets (salivary droplets) in the air are absorbed into the sterilizing water and removed by mixing.

Specifically, the first fine sterilizing water sprayed at high speed from the spray nozzle 320 collides with the walls of the sterilizing chamber 300, that is, the guide member 360 and the housing 310, and is adsorbed on the surface of the contaminated air, causing viruses, various It sterilizes and removes germs, droplets, etc.

Then, the fine second sterilizing water adsorbed on the surface of the contaminated air moves downward and becomes large water droplets, which fall from the housing 310 into the sterilizing water tank 400 and collect again.

Therefore, viruses, various bacteria, droplets, aerosols, etc. are killed by adsorption and mixing with the disinfection water.

Through this process, polluted air goes through the first purification process.

Referring to Figures 2 and 5, the triangular plate member 330 is formed in the lower part of the housing 310, and collects water droplets of the second sterilizing water that sterilizes the contaminated air in the lower part of the housing 310 and forms a sterilizing water tank. They fall to (400) and come back together.

A plurality of such triangular plate members 330 are arranged along the circumference of the lower surface of the housing 310, and each extends downward.

Additionally, the triangular plate member 330 has a funnel shape that becomes narrower as it goes downward.

Due to this, the triangular plate member 330 allows the second sterilizing water, which has sterilized the contaminated air, to accurately fall into the sterilizing water tank 400 while being collected toward the bottom.

Referring to Figures 2, 6A, and 6B, the mixing generator 340 is formed inside the housing 310, and a plurality of mixing generators 340 are formed at irregular positions.

This mixing generator 340 forms a vortex inside the housing 310 when the first sterilizing water and contaminated air sprayed from the spray nozzle 320 flow into the housing 310. .

Accordingly, the mixing generator 340 allows the external contaminated air and the first sterilizing water to mix more effectively with each other inside the housing 310.

Meanwhile, the mixing generator 340 may have a triangular shape as shown in FIG. 6A or a square shape as shown in FIG. 6B, or a combination thereof.

For example, the triangular mixing generator 340 is formed by cutting two of the three sides from the inner peripheral surface of the housing 310 and cutting the remaining side (dotted line in Figure 6A) toward the inside of the housing 310. do.

In addition, the mixing generator 340, which has a square shape, is formed by cutting two of the four sides from the inner peripheral surface of the housing 310 and cutting the remaining two sides (dotted lines in FIG. 6B) toward the inside of the housing 310. do.

Because of this, the mixing generator 340 allows the external contaminated air and the first sterilizing water to mix more effectively with each other inside the housing 310.

Meanwhile, in the housing 310 according to another embodiment of the present invention, an inlet member 350 may be disposed at the bottom to effectively collect the sprayed disinfectant water into large water droplets.

Referring to FIGS. 2 and 7 , the inflow member 350 is formed in the shape of a fallopian tube that widens from the bottom coupled to the housing 310 to the top, and the first sterilizing water sprayed from the spray nozzle 320 flows into the housing 310. ) so that it can be collected intensively inside.

Meanwhile, the housing 310 according to another embodiment of the present invention may have a plurality of guide members 360 disposed at the top.

Referring to FIGS. 2 and 8 , the guide members 360 are formed in a number corresponding to the spray nozzles 320 at positions corresponding to the spray nozzles 320 coupled to the upper part of the housing 310.

The guide member 360 is made of a cylindrical shape and surrounds the circumference of the injection nozzle 320.

Accordingly, as the flow rate increases, the internal pressure of the guide member 360 decreases, thereby increasing the suction force and the mixing force.

The sterilizing water tank 400 is disposed at the lower part of the sterilizing chamber 300 inside the case 100.

Additionally, the sterilizing water tank 400 sterilizes the contaminated air in the sterilizing chamber 300 and receives water droplets of the second sterilizing water that falls from the sterilizing chamber 300.

Meanwhile, a heater 410 may be placed inside the sterilizing water tank 400.

The heater 410 is accommodated inside the sterilizing water tank 400 and prevents the sterilizing water tank 400 from freezing and bursting in winter.

2 and 9, the electrolysis device 500 is accommodated inside the sterilizing water tank 400, and after sterilizing the contaminated air, it electrolyzes the second sterilizing water away from the sterilizing chamber 300 to produce water. It changes itself into the first sterilizing water with sterilizing power.

Specifically, the electrolysis device 500 is accommodated inside the sterilizing water tank 400, and after sterilizing the contaminated air in the sterilizing chamber 300, it electrolyzes the second sterilizing water contained in the sterilizing water tank 400 to produce HOCL. The sterilizing water changes the water itself into the first sterilizing water with sterilizing power.

As a result, the electrolysis device 500 can kill bacteria, viruses, etc. without the need to add separate detergents or chemicals to the second sterilizing water contained in the sterilizing water tank 400 and then reduce it to general water. there is.

And, even if this reduced general water is discharged into general sewage, secondary environmental pollution can be effectively prevented.

This electrolysis device 500 may include a pipe-shaped structure, a plurality of electrodes 510 and 520, a polymer electrolyte membrane (530, PEM; PROTON EXCHANGE MEMBRANE), and an electrode filter 540.

The first electrode 510 and the second electrode 520 are disposed inside and outside the zone based on a virtual preset zone inside the pipe-shaped structure, or are spaced apart from each other inside the pipe-shaped structure.

In addition, the first electrode 510 and the second electrode are pipe-shaped electrodes that have positive and negative polarity and each includes an internal space surrounded by the first electrode 510 and the second electrode 520.

When the liquid electrolyzed by the first and second electrodes is water, when water is electrolyzed, 2 H2O → 4 H + + 2 O + 4 eH + increases and OH - at the first electrode, that is, the (+) anode electrode. As a result of the decrease, a lot of oxidizing ions are generated, and the water electrolyzed inside the first electrode becomes oxygen-rich water. 2O eventually becomes O2 and some of it is dissolved in water, and negatively charged oxygen gathers at the first electrode 100, making water rich in oxygen. Negative ions gather at the first electrode and transfer electrons (e) to the first electrode. A deprivation reaction occurs.

Therefore, HOCL occurs according to the reaction equation: 2 Cl - + 2 e → Cl2, Cl2 + 2 H2O → 2 HClO + 2 H + + 2 e.

At the second electrode, that is, the (-) cathode electrode, OH - increases according to the reaction equation 4 H2O + 4 e → 4 OH - + 2 H2, and H + decreases, making hydrogen-rich water.

At this time, hydrogen (H2) gas is generated, some of which is dissolved in water, and hydrogen ions with positive charges gather at the second electrode to become antioxidant hydrogen-rich water.

Positive ions gather at the second electrode, and a reaction occurs in which electrons (e) are received from the second electrode.

At this time, some of the minerals such as calcium, magnesium, sodium, and potassium in the water are ionized together, and reducing ions are generated as the electrons (e) increase and the oxidation reduction potential (ORP) decreases to minus.

The polymer electrolyte membrane 530 is disposed between the first electrode and the second electrode and insulates or allows only ions to pass through.

The electrode filter 540 is at least one of a reducing block filter or a positive magnetic field filter that filters out impurities including residual chlorine in the second sterilizing water electrolyzed by the first electrode 510 and the second electrode 520. It can be included.

The first sterilizing water, which is changed from the second sterilizing water that sterilized the contaminated air as described above through the electrolysis device 500, is transferred to the spray nozzle 320 through the pump 900.

Accordingly, the first sterilizing water flows into the sterilizing chamber 300 through the spray nozzle 320, sterilizes the contaminated air to become the second sterilizing water, and then flows into the sterilizing water tank 400, and the sterilizing water tank ( The second sterilizing water flowing into 400) is electrolyzed through the electrolysis device 500 and converted into first sterilizing water.

Then, the first sterilizing water changed from the sterilizing water tank 400 is transferred to the spray nozzle 320 through the pump 900 to complete one cycle, and this cycle is repeated.

Accordingly, in the indoor air sterilizing and purifying device of the present invention, the first sterilizing water that purifies the polluted air and the second sterilizing water that purifies the polluted air are not discharged to the outside of the case 100.

In addition, the electrolysis device 500 operates only for the time during which the second sterilizing water is electrolyzed into the first sterilizing water according to the capacity of the sterilizing water tank 400.

That is, the electrolysis device 500 is turned off when the second sterilizing water is electrolyzed into the first sterilizing water, thereby saving electrical energy.

Referring to FIGS. 2 and 10 , the sterilizing device 600 is disposed inside the case 100 in an area in the direction in which the outlet 130 is formed with the partition wall 110 as the center.

In addition, the sterilizing device 600 first purifies the air sucked by the second fan member 220 coupled to the outlet 130 of the case 100 (with the first sterilizing water sprayed from the spray nozzle 320). purified air) secondarily.

This sterilizing device 600 consists of a UV-C ultraviolet light lamp or a plasma lamp.

The wavelength of these UV-C ultraviolet rays or plasma lamps is an electromagnetic wave that is shorter than visible light, and is broadly divided into three wavelength ranges: 100 to 400 nanometers (nm, one billionth of a meter).

Specifically, 315-400 nm is called ultraviolet A (UVA), 280-315 nm is called ultraviolet B (UVB), and 100-280 nm is called ultraviolet C (UVC). Among these, UVC with a wavelength of 100-280 nm has a sterilizing effect. It is used in sanitary sterilization products.

The wavelength of UVC used in these sanitary sterilization products is usually around 254nm.

Meanwhile, purification devices consisting of UV-C ultraviolet rays or plasma lamps decompose ozone at a faster rate and generate OH-radicals.

Specifically, ozone has strong absorption in the ultraviolet region of 253.7nm, and 1 mole of ozone and 1 mole of photons react to produce 1 mole of hydrogen peroxide, and the initially generated hydrogen peroxide decomposes ozone at a faster rate to produce OH-radicals. Create.

The original name of OH-radical is "Hydroxyl Radical", which is an oxygen anion-based natural substance produced by dissolving O₃ (ozone) in H₂O.

OH-radicals are involved in the sterilization and disinfection of almost all contaminants and are a natural substance that is harmless to the human body while exerting the most powerful chemical decomposition and removal effect.

Among existing substances, the oxidizing power (ability to sterilize, disinfect, and decompose) of OH-radicals is second only to fluorine (F), and is stronger than ozone (O₃) and chlorine (Cl₂), but is not toxic to the human body like fluorine, chlorine, and ozone. It is not a hazardous substance.

As a result of the initial reaction of OH-radical photolysis by ozone generated by electron impact and ultraviolet ray energy, hydrogen peroxide is generated as an intermediate substance.

And, OH-radicals are directly involved in pollutants and oxidize and reduce polluted organic substances into water (H2O) and oxygen.

Among the various technologies used in purification devices, TiO2 photocatalyst absorbs light and moves electrons from the valence band (VB) to the conduction band (CB), and the charge pairs generated at this time move to the boundary surface. It causes electronic transfer and causes oxidation and reduction reactions to proceed.

Taking advantage of this, purification is performed using TiO2/UVC Lamps that remove contaminants.

Using this technology, OH-radicals, which have a strong oxidizing power compared to ozone and are harmless to the human body, are generated and can be used to remove disease-causing substances such as bacteria and viruses and odor-causing substances.

Referring to FIGS. 2 and 11 , the filter member 700 is disposed inside the case 100 in an area in the direction in which discharge is formed with the partition wall 110 as the center.

Specifically, the filter member 700 is disposed between the second fan member 220 and the sterilizing device 600 inside the case 100.
