Description
본 고안은 광촉매-자외선을 이용한 실내공기 정화장치에 관한 것으로서, 보다 상세하게는 광촉매-자외선 기술을 이용하여 탈취와 살균기능이 일원화된 고효율, 저비용으로 다양한 실내공간에서의 공기오염에 대한 대응책과 처리장치를 제공하여 국민보건 증진은 물론 사회 보장비용의 절감에도 이바지 하는 광촉매-자외선을 이용한 실내공기 정화장치에 관한 것이다.The present invention relates to a device for purifying indoor air using photocatalyst-ultraviolet rays, and more specifically, to deal with and treat air pollution in various indoor spaces at high efficiency and low cost by unifying deodorization and sterilization using photocatalyst-ultraviolet technology. The present invention relates to an indoor air purifier using photocatalyst-ultraviolet rays, which contributes to the improvement of national health as well as the reduction of social security costs by providing a device.
종래에는 공기를 정화하기 위하여 일반적으로 폴리프로필렌(PP)수지 섬유 도는 폴리에틸렌(PE)수지 섬유를 이용하는 부직포 형태의 필터만을 사용하거나, 전기집진방식의 정전필터등을 사용하였다.Conventionally, in order to purify the air, only non-woven type filters using polypropylene (PP) resin fibers or polyethylene (PE) resin fibers are generally used, or electrostatic precipitating electrostatic filters are used.
그러나, 이러한 형식의 필터로는 먼지를 거르는 것은 가능하지만 그 구조상 악취를 제거하거나 세균을 살균하는 것은 어려웠다. 따라서 탈취를 위한 활성탄으로 만들어진 활성탄탈취필터를 사용하기도 하였으나, 활성탄필터로는 탈취성능 및 내구성이 좋지 않았고, 공기중에 포함된 유해한 미생물을 살균할 수 없는 문제점이 있다.However, it is possible to filter out dust with this type of filter, but its structure makes it difficult to remove odors or sterilize bacteria. Therefore, although an activated carbon deodorization filter made of activated carbon for deodorization is used, deodorization performance and durability are not good as an activated carbon filter, and there is a problem in that harmful microorganisms contained in the air cannot be sterilized.
이러한 문제점을 해결하기 위하여 광에너지에 의해 활성화되어 탈취와 살균기능을 각는 광촉매물질을 이용한 광촉매-자외선을 이용한 실내공기정화가 제안되고 있다.In order to solve this problem, indoor air purification using photocatalyst-ultraviolet using photocatalyst material activated by light energy and deodorizing and sterilizing functions has been proposed.
아래 [표1]은 광촉매로 사용할 수 있는 반도체와 산화환원 포텐셜을 나타낸 것이다.Table 1 below shows the semiconductor and redox potential that can be used as a photocatalyst.
일반적으로 광화학반응은 반도체의 결합전위에 의해 좌우되며, 촉매의 표면적과 결합전위 및 경제성을 고려할 경우 TiO2광촉매가 가장 적합하다.In general, the photochemical reaction is dependent on the bonding potential of the semiconductor, TiO2 photocatalyst is most suitable considering the surface area of the catalyst, the bonding potential and economic efficiency.
자외선은 1800대 초에 발견된 이래로 살균목적에 이용하기 시작한 것은 1877년 경부터 이며 오늘에 와서는 응용범위가 매우 광범위하고 응용 형태 역시 매우 다양하게 되었다.Since it was discovered in the early 1800's, UV rays began to be used for sterilization purposes around 1877. Today, the range of application is very wide and the types of application are very diverse.
자외선에 대해서 C.I.E(국제조염위원회)에서 분류는 [표 2]와 같다.The classification of ultraviolet rays in C.I.E (International Salt Making Committee) is shown in [Table 2].
상기 자외선은 특정한 파장을 중심으로 하여 고유의 특수한 작용을 하고 있는 것으로 나타나고 있으며 파장에 따른 특징은 [표 3]과 같다.The ultraviolet rays are shown to have a specific function inherent with respect to specific wavelengths, and the characteristics according to the wavelengths are shown in [Table 3].
광촉매-자외선을 이용한 탈취 및 살균작용은 다음과 같이 이루어진다.Deodorization and sterilization using photocatalyst-ultraviolet rays are performed as follows.

상기한 바와 같이, TiO2반도체 표면에 빛 에너지가 조사되면 TiO2valance band에 있는 전자가 conduction band로 전이되고 Valence band에는 전자가 비어있는 h+이 남게된다.As described above, when light energy is irradiated on the surface of the TiO 2 semiconductor, electrons in the TiO 2 valance band are transferred to the conduction band, and h +, which is empty of electrons, remains in the valence band.
이때, 전자가 전이되는데 필요한 광에너지로 band gab에 해당하는 3.2eV 정도의 에너지가 필요하며 390nm보다 짧은 파장이 이에 해당한다.At this time, 3.2eV energy corresponding to the band gab is required as the light energy required for electron transfer, and a wavelength shorter than 390nm corresponds to this.
이렇게 생긴 e- CB(conduction band에 전이된 전자)와, h+ VB(valence band에 남은 positive hole)은 TiO2표면에 확산되어 아래와 같은 연속적 과정을 거치게 된다.The e - CB (electrons transferred to the conduction band) and h + VB (positive hole remaining in the valence band) are diffused on the TiO 2 surface and subjected to the following continuous process.
이러한 몇 단계 과정을 거쳐서 생성된 OH·은 유기물과 반응하여 유기물을 파괴시키게 되는 것이다.The OH · generated through these several steps will react with the organics and destroy the organics.

상기 광촉매-자외선살균은 상기 도6에 도시된 바와 같이 TiO2반도체 표면에빛 에너지가 조사되면 TiO2가전자층(Valence band)에 있는 전자가 전도층(conduction band)로 전이되고 가전자층(Valence band)에는 전자가 비어있는 정공(h+)이 남게된다.The photocatalyst-UV sterilization is shown in FIG. TiO2When light energy is irradiated on the semiconductor surface, TiO2Electrons in the valence band are transferred to the conduction layer and holes are empty in the valence band.+) Will remain.
이때 전자가 전이되는데 필요한 광에너지로 밴드갭(band gab)에 해당하는 3.2eV(전자볼트) 정도의 에너지가 필요하며 390nm보다 짧은 파장이 이에 해당한다. 이렇게 생긴 가전자(e-CB)(conduction band에 전이된 전자)와, 정공(h+VB)(valence band에 남은 positive hole)은 TiO2표면에 확산되어 도6과 같은 연속적 과정을 거치게 된다.At this time, the energy required to transfer electrons requires energy of about 3.2 eV (electron volt) corresponding to a band gap, and a wavelength shorter than 390 nm corresponds to this. The resulting valence electrons (e- CB ) (electrons transitioned to the conduction band) and holes (h + VB ) (positive holes remaining in the valence band) are diffused onto the TiO 2 surface to undergo a continuous process as shown in FIG.
이러한 몇 단계 과정을 거쳐서 생성된 OH(수산기)가 유기물과 반응하여 유기물을 파괴 시키는 기술이다.OH (hydroxyl group) generated through these several steps is a technology that destroys the organic material by reacting with the organic material.

Excellent performance in the purification of non-degradable substances that did not exist.
또한, 탈취와 살균기능을 동일 시스템내에서 구현함으로써 비용대비 고효율의 정화기능을 실현 할 수 있게 한다.In addition, by implementing the deodorization and sterilization function in the same system, it is possible to realize a high-efficiency purification function.

여기서, 자외선램프(60)는 탈취작용과 살균작용이 동시에 가능한 280∼315nm의 자외선을 사용하며 정화장치의 크기에 따라 2W∼120W까지 다양하게 사용할 수 있다.Here, the ultraviolet lamp 60 uses ultraviolet rays of 280 ~ 315nm capable of both deodorizing and sterilizing at the same time and can be used in various ways from 2W to 120W depending on the size of the purification device.
상기 광촉매부재(70)는 석영관에 TiO2광촉매를 CVD방법으로 코팅시킨 광촉매코팅석영관 또는 세락믹담체에 TiO2를 도핑시킨 광촉매 도핑담체를 이용할수 있으며, SUS판에 TiO2를 코팅시킨 광촉매 코핑판을 이용할 수 있다.The photocatalyst member 70 may use a photocatalyst coated quartz tube coated with a TiO 2 photocatalyst on a quartz tube or a photocatalyst doped carrier in which TiO 2 is doped into a ceracic carrier, and a photocatalyst coated with TiO 2 on a SUS plate. Coping plates can be used.
또한, 상기 광촉매는 TiO2에 한정한 것은 아니며, 상기 광촉매-자외선기법으로 공기를 살균 및 탈취하는 것이다.In addition, the photocatalyst is not limited to TiO 2 , but sterilization and deodorization of air by the photocatalyst-ultraviolet technique.
그리고, 상기 AC/ACF필터(50)는 활성탄소섬유(Activated Carbon Fiber) 및 활성탄(Activated Carbon)으로 이루어진 필터로서 공기중의 각종 악취 및 유해가스를 제거하는 것으로서 도4에 그 다양한 형태를 예시하고 있다.In addition, the AC / ACF filter 50 is a filter made of activated carbon fiber and activated carbon to remove various odors and harmful gases in the air. have.
또한 상기 전처리필터(30) 및 중간필터(40)는 공기 중의 먼지 등을 제거하는 필터로서 세라믹필터로 구성함이 바람직할 것이다.In addition, the pretreatment filter 30 and the intermediate filter 40 may be preferably composed of a ceramic filter as a filter for removing dust and the like in the air.
즉, 상기와 같이 오염된 실내공기 중의 미세 고형물질등은 상기 전처리필터(30) 및 중간필터(40)에서 제거하고, 상기 실내공기 중의 악취 및 각종 유해가스는 AC/ACF필터(50)에서 제거한 후 상기 광촉매-자외선 살균장치로서 실내공기를 살균하도록 간단한 장치와 저유지 비용으로 실내공기를 쾌적하게 할 수 있는 것이다.That is, the fine solid material in the contaminated indoor air is removed from the pretreatment filter 30 and the intermediate filter 40, and the odor and various harmful gases in the indoor air are removed from the AC / ACF filter 50. After the photocatalyst-ultraviolet sterilization apparatus, the indoor air can be made comfortable with a simple device and low maintenance cost to sterilize the indoor air.
상술한 바와 같이 본 고안에 따르면, 에너지원으로 고가인 플라즈마 광원을 이용하지 않고, 비교적 저렴한 자외선을 사용하며, 정화장치의 구조가 간단하여 저비용으로 광촉매를 이용한 공기정화장치를 구현할 수 있는 장점이 있다.As described above, according to the present invention, there is an advantage in that an air purifier using a photocatalyst can be implemented at low cost without using an expensive plasma light source as an energy source, using relatively inexpensive ultraviolet light, and having a simple structure of a purifier. .
