1 is a block diagram of an air pollutant treatment apparatus according to an embodiment of the present invention. Hereinafter, the configuration of the air pollutant treatment apparatus according to an embodiment of the present invention will be described in detail with reference to FIG. 1 .

According to Fig. 1, the air pollutant treatment apparatus is composed of a plurality of members.

The pre-filter 10 filters the contaminants contained in the introduced air with the plate-type plasma and the tubular-type plasma reactor. The introduced air includes odors, industrial odors, complex odors, MERS, pathogenic bacteria, VOCs, fine dust, ultrafine dust, photochemical smoke, soot, smoke, and harmful toxic substances. The pre-filter 10 performs a function of primary filtering of contaminants included in the introduced air.

A Fibra-Web Filter 70 is positioned at the rear end of the pre-filter 10 .

At the rear end of the Fibra-Web Filter (70), a plate-type plasma and a tubular-type plasma (80) are positioned, and in addition, a first plate-type plasma and a tubular-type plasma (20) are positioned. Flat type plasma and tubular type plasma also perform a sterilization process for the introduced air, and in particular, constitute an ozone generation and oxidation system.

The combined filter removes smoke, oil vapor, fine dust, particulate matter, gaseous matter, odor and VOCs.

The HEPA filter 90 and the ULPA filter 100 are positioned at the rear end of the composite filter 60 . Hereinafter, the flow of the air pollutant treatment apparatus will be examined again using FIG. 2 .

Referring to FIG. 2 , external air containing contaminants such as odors and VOCs (volatile organic compounds) is introduced into the body having an inlet port.

As the introduced external air passes through the pre-filter 10 , various kinds of dust or foreign substances are filtered, and the first plate-type plasma, the tubular-type plasma, the Co-Mn/Ti catalyst reactor, and the filtering system 50 sequentially pass through the Contaminants are removed by UV and photocatalytic oxidation.

In addition, after allowing the residual unreacted contaminants to be adsorbed and removed through the composite filter 60 , the purified air from which the contaminants are completely removed is discharged to the outside.

The fan is used to introduce outside air polluted with odors into the inside through the inlet, and the purified air from which the odor has been removed can be discharged to the outside through the outlet at the rear.

The fan is connected to the motor and blows the air from the front to the rear by rotation caused by the driving of the motor. And inside the body, the pre-filter 10, the plate-type plasma and the tubular type plasma, the Co-Mn/Ti catalyst reactor and the filtering system 30, the first photocatalytic filter 50, and the composite filter 60 are sequentially and continuously installed at a distance.

Next, each filter installed inside the main body of the air pollutant treatment apparatus will be described.

The pre-filter 10 is installed adjacent to the inlet inside the body, and is used to remove general dust and foreign substances in the sucked external air.

And the first plate-type plasma, the tubular plasma, the Co-Mn/Ti catalyst reactor and the filtering system 30 are installed spaced apart from the rear of the pre-filter 10 by a predetermined distance, and the rear of the first photocatalytic filter 30 is A second photocatalytic filter 50 is installed.

The composite filter 60 is spaced apart from the rear of the second photocatalytic filter 50 by a predetermined distance and installed side by side, and includes an adsorbent filled in the filter frame and a hot wire formed inside the adsorbent.

Regarding ultraviolet (Ultra Violet, UV), the CIE (International Commission on Illumination) classified UVA (315-400 nm, near-ultraviolet), UVB (280-315 nm, mid-ultraviolet), and UVC (100-280 nm, far-ultraviolet) depending on the wavelength range. classify

Ultraviolet rays are shown to have a unique special action centered on a specific wavelength, and the characteristics according to the wavelength are shown in Table 1 below.

Range of wavelengths (nm) the strongest
Wavelength (nm) Action designation Application example 150～200 185.0 Generation of negative ions and ozone ozone generator Deodorization, water treatment, air purification 200-280 253.7 sterilization sterilizer Sterilization 280～320 296.7 erythema health line Light curing, erythema effect 320～380 365.0 chemical reaction actinic Light curing, fluorescent lamp

The planar plasma, tubular plasma, Co-Mn/Ti catalyst reactor and filtering system according to the present invention use UVA and UVC, respectively, and details will be described below.

First, the first plate-type plasma, the tubular-type plasma, the Co-Mn/Ti catalyst reactor, and the filtering system 20 will be described. The first UV lamp 20 includes the pre-filter 10 and the first flat plate-type plasma inside the body. It is installed in a space between the plasma and the tubular type plasma and the Co-Mn/Ti catalyst reactor and the filtering system 20, and directly irradiates UVC on the surface of the catalyst filter 20 to generate _{ozone (O 3 ).}

In particular, a wavelength of 150 nm or more and 200 nm or less, which is a range of wavelengths for generating ozone among UVC, is irradiated.

More specifically, oxygen (O ₂ ) and water (H ₂ O) molecules in the air are broken by UVC wavelengths to generate photoelectrons and ozone, and pollutants are oxidized and removed using ozone.

Ozone can completely or partially oxidize pollutants with 3000 times stronger oxidizing power than chlorine gas. Ozone directly oxidizes pollutants or generates radicals (OH) to oxidize and remove pollutants.

In addition, ozone has an excellent odor removal effect, and in _{the case of hydrogen sulfide (H 2} S), a major component of odor, it is treated completely harmlessly through the following reaction.

6H ₂ S+2O ₃ → 6H ₂ O+3S ₂

In addition, even in the case of methane gas (CH ₄ ), it reacts with ozone and is completely harmless.

2CH ₄ +4O ₃ → 3CO ₂ +6H ₂

Next, the second UV lamp 20 is installed in the space between the first photocatalytic filter 30 and the second photocatalytic filter 50 inside the main body.

The second plate-type plasma and the tubular-type plasma, the Co-Mn/Ti catalyst reactor and the filtering system 40 directly irradiate UVA to the surface of the second catalyst filter 50, and have a wavelength range of 350 nm or more and 380 nm or less. Irradiate with UVA.

Through this, radicals are generated and pollutants are oxidized and removed using radicals.

Ultraviolet absorption wavelength band of TiO ₂ serving as the photocatalyst upon irradiation of UV of 350nm ~ 400nm (UVA) in a wavelength (λ <400nm) having at least Band gap energy on the TiO ₂ surface e (electron on TiO ₂ surface, e ⁻ ) transitions from the valence band to the conduction band, thereby ^{creating holes (h +} ) in the valence band.

The electrons and holes generated in this way _{diffuse and move to the TiO 2} surface and undergo a redox process.

On the TiO ₂ surface, electrons react with oxygen _{to generate superoxide radicals (O 2} ^- ), and holes _{react with water molecules (H 2} O) or hydroxide ions (OH ^- ) in water to generate OH radicals.

In addition, the superoxide radical (O ₂ ⁻ ) ^{reacts with H +} to form H ₂ O to generate H ₂ O ₂ , and repeats the process of generating OH radicals through several reaction pathways.

The OH radical decomposes organic matter on the surface of _{TiO 2} with strong oxidizing power, which is called a photocatalytic reaction.

The generated OH radical is highly reactive and its energy is about 120 kcal/mol.

Most odor molecules and VOCs (volatile organic compounds) are composed of carbon-carbon, carbon-nitrogen, carbon-hydrogen, oxygen-hydrogen, nitrogen-hydrogen bonds, and their binding energy is around 100 kcal/mol, so OH radicals The bond can be easily broken by

As a result of that decomposition, we are comfortable and safe from odors and harmful VOCs.

In brief, TiO ₂ photocatalyst is an n-type semiconductor, and when exposed to ultraviolet light, electrons and holes are formed, electrons generate superoxide radicals (O ₂ ^- ), and holes generate OH radicals with strong oxidizing action.

In addition to the sterilization action, the OH radicals and superoxide radicals described above decompose organic compounds into water and carbon dioxide to make pollutants harmless.
