Abstract

PURPOSE: Provided is a device for treating air using an immobilized photocatalytic fiber filter which is able to completely remove persistent contaminants and harmful microorganism virus. CONSTITUTION: The device comprises reactors (11,12), fiber bundle type photocatalytic bundles (3a) installed on the inside of the reactors vertically to the air flow direction, an ultraviolet rays lamp (2) installed on the inside of the reactors to radiate ultraviolet rays to a fiber bundle type photocatalytic filter (3b) and an atmosphere discharge device (5) generating forcible atmospheric flow. The reactors form an atmosphere inflow dust removing filter and an atmosphere discharge device (5) and the fiber bundle type photocatalytic filter is mounted on the inner wall side thereof around the ultraviolet rays lamp. Clips (6a,6b) are installed on both sides of the reactors to be able to replace and mount the atmosphere inflow dust removing filter, the ultraviolet rays lamp and the fiber bundle type photocatalytic filter. The fiber bundle type photocatalytic bundles generate a tremor by the speed of the inflown atmospheric flow so that light contact area of each photocatalytic fiber type bundles becomes uniform. The atmospheric treatment flow speed is controlled by changing the atmospheric flow speed of the atmosphere discharge device according to the air contamination.

본 발명은 출원번호 10-2001-0066230의 특허 "수중오염물질을 제거 처리하기 위한 고정화된 이산화티탄 광촉매 및 이를 이용한 수처리 장치"를 이용하여 고정화된 광촉매를 이용한 섬유다발형 광촉매 필터와 이를 이용한 연속 흐름식 대기처리 장치에 관한 것으로, 더욱 자세하게는 난분해성 오염유기화합물 처리를 위하여, 고정화광촉매를 이용한 섬유다발형 광촉매 필터를 장착한 연속 흐름식 대기처리 장치로 대기중에 있는 유해 유기오염물질을 완전 산화, 분해시켜 대기오염물질을 정화함으로 청정한 대기환경을 제공함을 목적으로 한다. 각종 산업체와 환경기초 시설 등으로부터 배출되는 오염기체에 포함된 악취 및 VOC, NOx 등은 각종 대기 오염의 원인이 되며, 사무실, 가정, 병원, 학교등의 미생물에 의한 바이러스가 질병발생의 원인이 되고 있으며, 이런 대기환경 문제는 심각한 사회 및 경제적 문제로 대두되고 있다. 강한 분자결합을 가지고 있는 난분해성 대기오염 물질들은 기존의 활성탄 흡착, 약액세정, 촉매, 고온소각 등 다양한 물리화학적 방법으로 분해가 어려우며, 2차 오염물의 발생을 억제 할 수 없다. 대표적인 휘발성 유기 화합물(Volatile Organic Compound; 이하, VOC) VOC의 주요성분은 주요성분은 유기산, 알데히드류, 케톤류, 방향족 화합물 등이며, 악취물질로는 황화수소, 메틸메르캅탄과 같은 황화계 악취물질, 암모니아와 아민류와 같은 질소계가 있고, 유해 미생물 균으로는 집안에서 서식하는 곰팡이, 페니실린, 아스페길러스, 진드기, 바이러스잡균 등이 있다. 이러한 난분해성 물질 및 악취, 미생물 바이러스 등은 단시간에 확산되어 종래의 기술로는 효과적인 처리 및 제거가 곤란하다.The present invention is a fibrous bundle type photocatalyst filter using a fixed photocatalyst using a patented "immobilized titanium dioxide photocatalyst for removing pollutants in water and a water treatment apparatus using the same" and a continuous flow using the patent of Patent No. 10-2001-0066230 The present invention relates to a type of air treatment device. More specifically, in order to process hardly degradable contaminated organic compounds, a continuous flow type air treatment device equipped with a fiber bundle type photocatalyst filter using an immobilized photocatalyst is used to completely oxidize harmful organic pollutants in the air. It aims to provide a clean air environment by decomposing and purifying air pollutants. Odor, VOC, NOx, etc. contained in polluted gas discharged from various industrial and environmental base facilities cause various air pollution, and virus caused by microorganisms such as office, home, hospital, school, etc. In addition, these environmental problems are becoming serious social and economic problems. Refractory air pollutants with strong molecular bonds are difficult to decompose by various physicochemical methods such as adsorption of activated carbon, cleaning of chemical liquids, catalysts, and high-temperature incineration, and cannot suppress the generation of secondary pollutants. Representative Volatile Organic Compounds (VOCs) The main components of VOC are organic acids, aldehydes, ketones, aromatic compounds, etc., and odorous substances include sulfide-based odorous substances such as hydrogen sulfide and methyl mercaptan, and ammonia. There are nitrogen-based, such as amines, and harmful microorganisms include fungi, penicillin, aspergillus, mites, virus germs living in the house. Such hardly decomposable substances, odors, microbial viruses, etc., are spread in a short time, and thus, effective treatment and removal are difficult by the conventional technology.

광촉매는 n형 반도체로서 산화 환원 반응은 자외선(365nm이하)파장에서 광촉매 표면에서의 전자(Electron),와 정공(Hole)이 생성 정공은 표면의 수분과 반응하여 강한 산화력이 있는 하이드록시라디칼(OH-)을 생성 전자대는 흡착된 산소에 전자를 줌으로써 슈퍼옥사이드(O2￣)를 생성하게 되어 하이드록시 라디칼과 슈퍼 옥사이드가 광촉매 표면에 흡착된 유기물질의 분자결합을 제거하여 물과 탄산가스로 변화시키며, 세균도 유기 화합물이므로 광촉매의 강한 산화 및 환원작용에 의해 완전분해 되어 살균된다. 자외선의 광에너지 hv가 광촉매 결합에너지(Band gap energy) 보다 같거나 그 이상이 되면 광촉매의 가전자대(Valence and)에서 전자가 방출되게 된다.The photocatalyst is an n-type semiconductor, and the redox reaction generates electrons and holes on the surface of the photocatalyst at ultraviolet (365 nm or less) wavelengths. The electron band produces electron oxides on the adsorbed oxygen to generate superoxide (O2), which removes the molecular bonds of hydroxy radicals and organic compounds adsorbed on the surface of the photocatalyst to water and carbon dioxide. As bacteria are also organic compounds, they are completely decomposed and sterilized by strong oxidation and reduction of photocatalysts. When the light energy hv of ultraviolet rays is equal to or greater than the band gap energy, electrons are emitted from the valence and photocatalyst.

hv + photoenergy = h+ + e-hv + photoenergy = h + + e-

광촉매 활성을 위한 근자외선 영역은 (360nm 이하) 광촉매 내부에서의 전하를 띠는 potential 의 변동으로 전공을 표면으로 이동시키게 된다.The near-ultraviolet region for photocatalytic activity (360 nm or less) moves the pores to the surface due to variations in the charged potential inside the photocatalyst.

광촉매 표면에서는 e-cb 와 h+vb 가 발생되어지며, 발생되어진 전자 (e-tr)와 정공(h+tr )은 공극으로 이동하게 된다. 이 과정 중 산소의 존재로 Superoxide (O2-) 음이온 Radical 이 발생되어지게 되어 환원제의 역할을 하게되며 광촉매 표면에 흡착된 음이온은 Hole과 반응하여 OH Radical을 형성하게 된다.On the surface of the photocatalyst, e-cb and h + vb are generated, and the generated electrons (e-tr) and holes (h + tr) move to the pores. During this process, superoxide (O2-) anion radical is generated due to the presence of oxygen, which acts as a reducing agent, and the anion adsorbed on the surface of the photocatalyst reacts with the hole to form OH radical.

e-tr + OH- → OHe-tr + OH- → OH

또한 Hole은 물을 산화시키거나, 수산화이온과 반응하여 OH Radical을 형성한다.Holes also oxidize water or react with hydroxide ions to form OH Radicals.

h+tr + H2O → OH + H+h + tr + H2O → OH + H +

이러한 반응 메카니즘의 발생과 더불어 전자 전공의 발생으로 유기화합물의 분자구조를 제거할 수 있는 OH Radical을 생성할 수 있으며, 전자 전공의 발생과 동시에 재결합현상도 발생하므로, 분리와 결합이 동시적으로 시행되어진다. 이러한 전자 전공의 재결합 반응은 생성된 전공과 전자가 공간 전하층에서 전자대의 휨은 생성된 전공과 전자가 서로 반대 방향으로 움직이게 함으로서 궁극적으로 전자와 전공의 재결합을 방지하는 효과를 나타내게 된다. 이에 따라 생성된 전공과 전자가 촉매반응에 참여할 수 있는 가능성이 커지므로 이와 같은 현상은 불균일계 광촉매 반응에 있어서, 중요한 요소라고 할 수 있다. 광촉매 종류 중에 아나타제형과 루타일형으로 크게 나누고 있지만 아나타제형 광촉매는 전자 전공의 재결합 속도가 느리며, 산소 흡착능력이 우수하여 일반적으로 환경정화 응용분야에 적용하고 있다.In addition to the reaction mechanism, the generation of electron majors can be used to generate OH Radicals that can remove the molecular structure of organic compounds. It is done. The recombination reaction of the electron holes causes the generated holes and electrons to bend in the space charge layer, thereby causing the generated holes and the electrons to move in opposite directions, thereby ultimately preventing the recombination of the electrons and the holes. Accordingly, since the generated major and electrons are more likely to participate in the catalytic reaction, such a phenomenon is an important factor in the heterogeneous photocatalytic reaction. Among the photocatalysts, the anatase and rutile types are largely classified, but the anatase photocatalysts are generally applied to environmental purification applications because of their slow recombination rate and their excellent oxygen adsorption capacity.

Contact between photocatalyst and noxious substances by photocatalyst coating on support in device structure or photocatalyst coating on filter and honeycomb type object.
