Abstract
본 발명은 플라즈마 셀이 입체형으로 구성된 플라즈마 필터를 이용한 공기정화 장치 및 그 방법에 관한 것이다.The present invention relates to an air purification apparatus and method using a plasma filter having a three-dimensional plasma cell.
본 발명의 입체형 셀 구조의 플라즈마 필터를 이용한 공기정화 장치 및 그 방법은 오염된 공기가 1차 여과되는 프리필터부(2); 상기 프리필터부(2)에서 1차적으로 여과된 공기를 흡입하여 플라즈마 필터부(4)로 보내는 송풍부(3); 상기 송풍부(3)를 통해 나오는 공기를 대기압 글로우 플라즈마 방전에 의해 2차적으로 정화시키는 플라즈마 셀이 입체적으로 배열된 플라즈마 필터부(4); 및 상기 플라즈마 필터부(4)와 연결된 플라즈마 전원 공급장치를 포함하는 공기정화 장치(1)와 그 정화 방법에 관한 것으로서, 상기 플라즈마 필터부(4)는 토르말린(tourmaline) 또는 TiO2가 혼합된 재료로 글레이징(glazing) 처리가 되어 있는 플라즈마 셀이 3차원의 격자구조, 선반구조 및 와이어구조와 이들의 혼합구조를 가지도록 설계되어 있음에 기술적 특징이 있다.Air purifying apparatus and method using the three-dimensional cell structure of the plasma filter of the present invention comprises a pre-filter unit 2 to filter the polluted air first; A blower (3) for sucking air primarily filtered from the prefilter (2) and sending it to the plasma filter (4); A plasma filter unit (4) having three-dimensionally arranged plasma cells for secondaryly purifying air emitted through the blower unit (3) by atmospheric glow plasma discharge; And a plasma power supply device connected to the plasma filter unit 4 and a purifying method thereof, wherein the plasma filter unit 4 comprises tourmaline or TiO 2 mixed material. The technical feature is that the plasma cell subjected to the glazing process is designed to have a three-dimensional lattice structure, a shelf structure, a wire structure, and a mixed structure thereof.
따라서, 본 발명의 입체형 셀 구조의 플라즈마 필터를 이용한 공기정화 장치 및 그 방법은 부가적인 필터나 전기집진 장치를 구비하지 않아도 단독으로 정화가 가능하기 때문에 비용이 절감되며 장비의 효율성을 극대화할 수 있고, 기존의 코로나 방전에 비하여 오존 발생이 현저히 줄어든다는 장점이 있다. 또한 플라즈마 필터가 3차원의 구조를 가지는 플라즈마 셀로 이루어져 있기 때문에 공기와의 접촉면적이 넓어서 공기정화 효율이 증가되고, 글레이징 처리된 표면에서 음이온 방출 물질인 토르말린에 흡수되어 음이온 방출을 극대화할 수 있으며 광촉매인 TiO2와 반응함으로써 많은 활성 라디칼을 생성하기 때문에 병원성 미생물이나 대기 오염 물질들을 효과적으로 제거할 수 있는 효과가 있다.Therefore, the air purification device and the method using the three-dimensional cell structure of the plasma filter of the present invention can be purified without the need for additional filters or electrostatic precipitator can reduce the cost and maximize the efficiency of the equipment As a result, ozone generation is considerably reduced compared to the conventional corona discharge. In addition, since the plasma filter is composed of a plasma cell having a three-dimensional structure, the contact area with air is wide, which increases the air purification efficiency, and is absorbed by tourmaline, an anion-releasing material, on the glazed surface to maximize the anion emission. By reacting with TiO 2 , it generates many active radicals, which effectively removes pathogenic microorganisms and air pollutants.
Description
본 발명은 입체형 셀 구조의 플라즈마 필터를 이용한 공기정화 장치 및 그 방법에 관한 것으로, 보다 자세하게는 플라즈마 방전을 이용한 공기정화기에 있어서, 플라즈마 셀이 입체형으로 제작된 플라즈마 필터를 사용하여 글로우 방전을 일으키고 공기를 직접 통과시킴으로써 부가적인 필터나 전기집진 장치를 필요로 하지 않는 방법이다. 또한 플라즈마 셀을 음이온 발생체인 토르말린(tourmaline)과 광촉매인 TiO2를 혼합한 물질로 글레이징(glazing) 처리하여 음이온 방출효과와 광촉매에 의한 다량의 활성라디칼을 생성시켜 오염된 공기를 정화할 수 있는 장치 및 그 방법에 관한 것이다.The present invention relates to an air purifying apparatus using a plasma filter having a three-dimensional cell structure and a method thereof, and more particularly, to an air purifier using plasma discharge, by using a plasma filter made of a three-dimensional plasma cell to generate a glow discharge and air The direct pass through eliminates the need for additional filters or electrostatic precipitators. In addition, the plasma cell is glazed with a mixture of tourmaline, an anion generator, and TiO 2 , a photocatalyst, to generate polluted air by generating an anion emission effect and a large amount of active radicals by a photocatalyst. And to a method thereof.
공기를 정화시키는 방법에는 해파 필터를 포함하는 필터류를 이용하는 방법, 물의 흡착력을 이용하는 방법, 전기집진기를 이용한 코로나 방전에 의한 방법, TiO2를 포함하는 광촉매를 이용하는 방법 및 대기압 플라즈마를 이용하는 방법 등 여러 가지를 들 수 있다.There are various methods of purifying air, including a method using a filter including a sea wave filter, a method using water adsorption force, a method by corona discharge using an electrostatic precipitator, a method using a photocatalyst including TiO 2 , and a method using an atmospheric plasma. Can be mentioned.
그 중에서도 플라즈마 방전 및 광촉매 작용에 의한 공기 정화 방법으로는 미국특허 제5,827,407호, 한국등록특허 제0317798호, 한국등록특허 제0195935호 등에 개시되어 있는데, 상기의 연구들은 코로나 방전에 의한 공기 정화 방법으로서, 전기집진기를 구배하고 있어서 미세한 먼지를 집진할 수 있고 반영구적으로 사용할 수 있어서 필터를 교체하는 비용이 들지 않는다는 장점이 있다. 그러나, 방전을 일으키기 위한 고전압을 공급해 주어야 하고 코로나 방전에 의하여 오존이 다량 발생한다. 또한 이 오존 발생량을 감소시키기 위해서 광촉매제를 주로 사용하게 되는데 TiO2를 포함하는 광촉매제는 태양광이나 자외선과 같은 빛을 필요로 하기 때문에 부가의 자외선 램프 등의 장치가 더 구비되어야 하는 단점이 있다.Among them, methods for purifying air by plasma discharge and photocatalytic action are disclosed in US Pat. No. 5,827,407, Korean Patent No. 0317798, Korean Patent No. 0195935, and the like. In addition, since the electric dust collector is gradient, fine dust can be collected and semi-permanently used so that there is no cost to replace the filter. However, a high voltage must be supplied to generate a discharge, and a large amount of ozone is generated by corona discharge. In addition, photocatalysts are mainly used to reduce the amount of ozone generated. Since photocatalysts including TiO 2 require light such as sunlight or ultraviolet rays, there is a disadvantage that additional devices such as ultraviolet lamps should be further provided. .
따라서, 본 발명은 상기와 같은 종래 기술의 제반 문제점을 해결하기 위한 것으로, 코로나 방전보다 안정적인 대기압 글로우 플라즈마 방전을 일으킬 수 있는 플라즈마 필터를 사용하여 오염된 공기를 직접 통과시켜 정화하고, 상기 플라즈마 필터의 전극 역할을 하는 플라즈마 셀을 입체형으로 구성하여 오염된 공기와의 접촉면을 증가시킴으로써 정화 효율을 향상시킬 수 있도록 한다. 또한 오존 발생을 최소화하면서도 부가적인 필터나 전기집진 장치가 없이도 다량의 활성라디칼과 음이온을 발생시킬 수 있는 공기정화 장치 및 그 방법을 제공함에 본 발명의 목적이 있다. Accordingly, the present invention is to solve the above-mentioned problems of the prior art, by using a plasma filter that can cause a stable atmospheric pressure plasma plasma discharge than the corona discharge to directly pass through the contaminated air to purify, Plasma cells serving as electrodes form a three-dimensional shape to increase the contact surface with the contaminated air to improve the purification efficiency. In addition, it is an object of the present invention to provide an air purifying apparatus and method capable of generating a large amount of active radicals and anions without additional filter or electrostatic precipitator while minimizing ozone generation.
본 발명의 상기 목적은 오염된 공기가 1차 여과되는 프리필터부(2); 상기 프리필터부(2)에서 1차적으로 여과된 공기를 흡입하여 플라즈마 필터부(4)로 보내는 송풍부(3); 상기 송풍부(3)를 통해 나오는 공기를 대기압 글로우 플라즈마 방전에 의해 2차적으로 정화시키는 플라즈마 셀이 입체적으로 배열된 플라즈마 필터부(4); 및 상기 플라즈마 필터부(4)와 연결된 플라즈마 전원 공급장치로 이루어진 공기정화 장치(1) 및 그 방법에 의해 달성된다.The above object of the present invention is a pre-filter unit 2, the polluted air is first filtered; A blower (3) for sucking air primarily filtered from the prefilter (2) and sending it to the plasma filter (4); A plasma filter unit (4) having three-dimensionally arranged plasma cells for secondaryly purifying air emitted through the blower unit (3) by atmospheric glow plasma discharge; And an air purifying apparatus 1 composed of a plasma power supply connected to the plasma filter unit 4 and a method thereof.
특히, 본 발명의 공기정화 장치(1)에 구비된 플라즈마 필터부(4)는 토르말린(tourmaline) 또는 TiO2가 혼합된 재료로 글레이징(glazing) 처리가 되어 있는 플라즈마 셀이 3차원의 격자구조, 선반구조 및 와이어구조와 이들의 혼합구조를 가지도록 설계되어 있어서 정화대상이 되는 공기와의 접촉 면적이 넓고, 교류전원이 인가되면 안정적인 대기압 글로우 플라즈마 방전이 이루어져 오존 발생을 최대한 억제하면서도 공기 정화 능력이 우수한 다량의 활성라디칼과 음이온이 발생하여 공기를 정화하는 장치 및 그 방법에 관한 것이다.In particular, the plasma filter unit 4 included in the air purifying apparatus 1 of the present invention has a three-dimensional lattice structure of a plasma cell in which a glazing treatment is performed with a material mixed with tourmaline or TiO 2 . It is designed to have a shelf structure, a wire structure, and a mixed structure thereof, so that the contact area with the air to be purified is large, and when an AC power is applied, a stable atmospheric glow plasma discharge is generated, which minimizes ozone generation while providing air purification ability. The present invention relates to a device and a method for purifying air by generating good amounts of active radicals and anions.

For example, in FIG. 2B having a three-dimensional shelf structure, a pair of plasma unit units 41 and 42 of each layer may serve as an electrode. It may also consist of a pair of electrodes 41 and 43 and a layer 42 coated with a functional material having purifying capability.

도 3c와 도 3d는 상기 플라즈마 셀이 전도성 전극(5)과 유전체(6)로 이루어진 일체형의 전극일 경우를 나타낸 것으로서, 상기 전도성 전극(5)이 유전체(6) 내에 삽입되거나 유전체의 양면에 위치하고, 유전체 위에는 전도성 전극(5)의 내구성 및 산화방지를 위해서 PbO, ZnO, B2O3 또는 SiO2를 포함하는 산화물에 광촉매 재료인 TiO2 또는 음이온 발생체인 토르말린(Tourmaline) 분말이 혼합된 수 ㎛ 이내의 재료로 글레이징(glazing) 처리한다.3C and 3D show the case where the plasma cell is an integrated electrode consisting of the conductive electrode 5 and the dielectric 6, wherein the conductive electrode 5 is inserted into the dielectric 6 or located on both sides of the dielectric. On the dielectric, several μm of TiO 2 or a tourmaline powder, an anion generator, is mixed with an oxide including PbO, ZnO, B 2 O 3, or SiO 2 to prevent durability and oxidation of the conductive electrode 5.

도 4는 본 발명에 의한 실시예를 나타낸 개념도로서, 여기에서는 상기의 도 3c와 도 3d에서 나타낸 일체형의 전극으로 이루어진 플라즈마 필터부(4)를 나타내었다. 일체형의 전극으로 이루어진 플라즈마 필터부(4) 두 개가 일정한 각도를 이루면서 전원부에 연결되고, 토르말린, TiO2 와 같은 기능성 물질이 도포된 기능성 전극(47)이 더 구비될 수도 있게 하여 대기압 플라즈마 방전을 극대화할 수 있는 구조이다. 즉, 이와 같은 구조를 가지는 공기정화 장치는 0∼90°의 각도로 서로 대향되게 배치된 적어도 두 개 이상의 플라즈마 필터부(4)에 의하여 대기압 플라즈마 방전이 이루어지고, 여기에 기능성 물질이 도포된 전극(47)에 의하여 더 많은 음이온과 활성라디칼을 생성하게 되므로 정화 능력을 향상시킬 수 있다.FIG. 4 is a conceptual view showing an embodiment according to the present invention, in which the plasma filter unit 4 including the integrated electrodes shown in FIGS. 3C and 3D is shown. Two plasma filter parts 4 formed of an integrated electrode are connected to the power supply unit at a predetermined angle, and a functional electrode 47 coated with a functional material such as tourmaline or TiO 2 may be further provided to maximize atmospheric pressure plasma discharge. It is a structure that can be done. That is, in the air purifying apparatus having such a structure, an atmospheric pressure plasma discharge is performed by at least two plasma filter units 4 disposed to face each other at an angle of 0 to 90 °, and an electrode coated with a functional material thereon. By (47), since more anions and active radicals are produced, the purification ability can be improved.
이와 같은 공기정화 장치를 이용한 공기 정화 방법은 공기정화 장치(1) 내부의 송풍부(3)에 의해서 오염된 공기가 유입되는 제 1단계, 상기 유입된 공기가 프리필터부(2)에 의해 1차 여과되는 제 2단계, 상기 1차 여과된 공기가 송풍부(3)에 의해 플라즈마 필터부(4)로 유입되는 제 3단계, 상기 플라즈마 필터부(4)의 대기압 글로우 플라즈마 방전에 의해 공기가 정화되는 제 4단계 및 상기 정화된 공기가 송풍부(4)에 의하여 외부로 배출되는 제 5단계로 이루어진다. 즉, 병원성 미생물이나 대기오염 물질인 이산화탄소(CO2), 일산화탄소(CO), 질소산화물(NOX), 황산화물(SOX), 포름알데히드, 담배연기 및 각종 유기화합물 등으로 오염된 공기가 강력한 송풍부(3)에 의해서 유입되고 프리필터부(2)를 지나면서 1차 여과된다. 그리고 수백V∼수십kV의 교류전원과 주파수 10∼105Hz인 전원이 플라즈마 필터부(4)로 인가되면 플라즈마 셀이 단독 또는 대향된 두 개의 전극으로 작용하여 플라즈마 필터부(4)에서 대기압 글로우 방전을 일으키게 된다. 글로우 방전은 코로나 방전이나 스트리머성 방전과는 달리 주변의 공기와 공기속의 소량의 수분(H2O)을 이용하여 오존발생을 최대한 억제하면서 공기 정화 능력이 우수한 다량의 활성라디칼과 음이온을 발생시킨다. 이 때 방출된 음이온은 글레이징 처리된 표면에서 음이온 방출 물질인 토르말린에 흡수되어 훨씬 더 많은 음이온을 방출하게 되고, 또한 광촉매인 TiO2가 글로우 방전시 생성되는 빛에 의해 반응이 일어나 활성라디칼을 생성하게 되어 여러가지 오염물질에 의해 오염된 공기가 청정한 공기로 정화된다.The air purifying method using the air purifying device includes a first step in which air contaminated by the blower part 3 inside the air purifying device 1 flows in, and the introduced air is transferred by the prefilter part 1. The second step of the secondary filtration, the third step of the primary filtered air is introduced into the plasma filter unit 4 by the blower (3), the air by the atmospheric pressure plasma discharge of the plasma filter unit (4) The fourth step of purification and the fifth step of the purified air is discharged to the outside by the blower (4). That is, air contaminated with pathogenic microorganisms or air pollutants such as carbon dioxide (CO 2 ), carbon monoxide (CO), nitrogen oxides (NO X ), sulfur oxides (SO X ), formaldehyde, tobacco smoke and various organic compounds It is introduced by the blower section 3 and is first filtered while passing through the prefilter section 2. When an AC power source of several hundred Vs to several tens of kVs and a power source having a frequency of 10 to 10 5 Hz are applied to the plasma filter unit 4, the plasma cell acts alone or as two opposite electrodes, causing atmospheric glow in the plasma filter unit 4. Will cause a discharge. Glow discharge, unlike corona discharge and streamer discharge, generates large amount of active radicals and anions with excellent air purification ability while minimizing ozone generation by using small amount of water (H 2 O) in surrounding air and air. . The released anions are absorbed by the tourmaline, an anion-releasing material, on the glazed surface, releasing even more anions, and the photocatalyst TiO 2 reacts with the light generated during glow discharge to generate active radicals. The air contaminated by various pollutants is purified to clean air.
따라서, 본 발명의 입체형 셀 구조의 플라즈마 필터를 이용한 공기정화 장치 및 그 방법은 토르말린과 TiO2가 혼합된 재료로 글레이징 처리된 플라즈마 셀을 3차원의 입체구조를 가지도록 설계한 플라즈마 필터를 사용함으로써 자체적으로 대기압 글로우 플라즈마 방전을 일으켜 부가적인 필터나 전기집진 장치를 구비하지 않아도 단독으로 정화가 가능하기 때문에 비용 및 장비의 효율성을 극대화 할 수 있고, 오존의 발생이 현저히 줄어들면서도 음이온 발생체인 토르말린과 광촉매인 TiO2의 반응에 의해 많은 양의 활성라디칼을 형성시킴으로써 병원성 미생물이나 대기 오염 물질들을 효과적으로 제거할 수 있는 효과가 있다.Therefore, the air purifying apparatus and method using the three-dimensional cell structure plasma filter of the present invention by using a plasma filter designed to have a three-dimensional three-dimensional structure of the plasma cell glazed with a mixture of tourmaline and TiO 2 By generating atmospheric glow plasma discharge by itself, it is possible to purify by itself without additional filter or electrostatic precipitator, so it is possible to maximize the cost and efficiency of the equipment. By forming a large amount of active radicals by the reaction of TiO 2 , there is an effect that can effectively remove pathogenic microorganisms or air pollutants.
