Abstract
본 발명은 도로 구조물 중에 하나인 터널 및 지하차도 내부에 광촉매 코팅에관한 것이다.The present invention relates to a photocatalyst coating inside tunnels and underground roadways, one of the road structures.
기존 터널 및 지하차도는 자동차의 배기가스에 의하여 심하게 오염되어 있으며 운전자가 터널 및 지하차도를 운전시 오염물질로 인하여 매우 불쾌감을 느끼고 설계시에도 터널 및 지하차도에 오염물질을 배출하기 위해 많은 예산과 시설물을 설치하고 있는 실정이다.Existing tunnels and underground roads are heavily polluted by the exhaust gas of vehicles, and drivers are very uncomfortable with pollutants when they drive tunnels and underground roads. The facility is being installed.
이에 광화학 작용에 의하여 오염물질을 분해하고 초친수성에 의하여 오염물질 부착력을 약화시키는 이산화티탄을 주성분으로 하는 광촉매를 코팅하므로써 터널내 오염물질을 차량의 주행풍이나 자연바람에 의하여 용이하게 세정되게 하고 아울러 터널내부 조명으로 유해가스를 분해 정화할 수 있게 하는 것을 특징으로 한다.The photocatalyst has a photocatalyst based on titanium dioxide that decomposes pollutants by photochemical action and weakens the adhesion of pollutants by superhydrophilicity, so that pollutants in tunnels can be easily cleaned by vehicle wind or natural wind. The interior of the tunnel is characterized in that it is possible to decompose and clean the harmful gas.

2. 지하차도 내부(코팅작업 예시)2. Underground roadway (coating work example)
본 발명은 도로 구조물중 차량의 배기가스에 가장 영향을 많이 받는 터널내부 및 지하차도내 오염방지를 위한 광촉매 코팅에 관한 것으로 보다 상세하게 설명하자면 도로 구조물중 폐쇄적 공간인 터널내부 및 지하차도 내부에는 차량의 배기가스 및 디젤엔진 차량의 매연으로 인해 심하게 오염되어 있으며 이를 완화하기 위해 환기시설물(젯트펜 등)을 설치하고 설치 시설물로 인한 터널내공단면 확대 및 시공비가 많이 증가되고 실정이다.The present invention relates to a photocatalyst coating for preventing pollution in tunnels and underground roadways most affected by vehicle exhaust gases among road structures. More specifically, the present invention relates to a vehicle inside a tunnel and an underground roadway, which are closed spaces in road structures. It is heavily polluted by the exhaust gas of the exhaust gas and diesel engine vehicles, and in order to alleviate this, the installation of ventilation facilities (jet pens, etc.), and the expansion and construction costs in the tunnel area due to the installation facilities are increasing.
또한 내부청소를 위해 년2회 차량을 우회 및 통제하며 많은 인력과 재원이 소요되고 있는 실정이다In addition, the vehicle is bypassed and controlled twice a year for internal cleaning, and a lot of manpower and resources are required.
종래의 광촉매를 이용하는 코팅으로는 수족관.수조의 벽에 코팅하여 이끼가 발생하지 않토록 한다거나 건축물의 외장재나 유리창에 코팅하여 건물의 외관이나 유리창을 깨끗하게 유지하는 등의 이용방법은 공지된 바 있었다. As a coating using a conventional photocatalyst, a method of coating a wall of an aquarium or a water tank so as to prevent moss from occurring or coating an exterior material or a glass window of a building to keep a building's exterior or a glass window clean has been known.
본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로 광분해 효과와 초친수성을 가진 광촉매를 터널내부 및 지하차도 내부에 코팅처리 하므로써 터널내부의 오염물질을 광화학반응으로 분해하고 초친수성으로 부유분진의 부착력을 감소시켜 터널내의 자연풍 및 차량주행풍을 이용하여 오염물질을 쉽게제거 될 수있게 하는 것을 목적으로 한다.The present invention has been made to solve the above problems by coating the photocatalyst having photodegradation effect and super hydrophilicity inside the tunnel and the underground roadway to decompose contaminants in the tunnel by photochemical reaction and superhydrophilic The purpose is to reduce the adhesion and make it easier to remove contaminants by using natural wind and vehicle driving wind in the tunnel.
본발명의 또다른 목적은 차량배기가스중에 있는 오염물질을 터널 및 지하차도 내부의 조명 및 주행차량의 조명을 이용한 광촉매에 의하여 분해. 제거하여 대기정화 및 터널(지하차도)공사비 절감에도 기여하게 하는 것이다.Another object of the present invention is to decompose contaminants in vehicle exhaust gases by photocatalysts using the lights inside tunnels and underground roadways and the lights of driving vehicles. It will also contribute to reducing air purification and tunnel (underground) construction costs.
본 발명은 상기와 같은 목적을 달성하기 위하여 이산화티탄(TiO2)와 같은 광촉매가 자외선과 반응할 시 활성이 높은 OH나 O2와 같은 활성산소를 생성하여 오염물질을 물이나 이산화탄소로 산화시켜 제거하는 성질과 이산화 티탄이 가지는 초 친수성에 의하여 오염물질이 표면에 쉽게 달라붙지 않고 달라붙은 오염물질도 광화학반응에 의하여 산화되거나 자연풍 및 차량주행풍에 의하여 쉽게 제거될수 있게하는 도로구조물(터널내부,지하차도) 내부에 광촉매를 코팅하는 구성을 제공한다.In order to achieve the above object, the present invention generates highly active oxygen such as OH or O2 when a photocatalyst such as titanium dioxide (TiO2) reacts with ultraviolet rays to oxidize and remove contaminants with water or carbon dioxide. Road structures that allow pollutants not easily stick to the surface due to superhydrophilicity of titanium dioxide and are easily oxidized by photochemical reactions or easily removed by natural winds and vehicle driving winds (inside tunnels) It provides a configuration for coating the photocatalyst therein.
먼저 광촉매에 관하여 설명하자면 광촉매는 장외선에 의해 여기되면서 표면에서 화학반응을 촉진시키는 활성산소를 생성하는 물질을 총칭하는 것으로 원인물질로는 이산화티탄(TiO2), 산화지르코늄(ZrO2),산화비소(Sb2ㅐ4), 산화아연(ZnO), 산화주석(ZnO2),산화세륨(CeO2),산화텅스텐(WO3) 및 산화철(Fe2O3)등이 공지되어 있으나 일반적으로 이산화티탄이 가장 널리 사용되고 있다.First of all, the photocatalyst is a generic term for a substance that generates active oxygen that is excited by long-term ultraviolet rays and promotes chemical reactions on its surface. The causative agents include titanium dioxide (TiO2), zirconium oxide (ZrO2), and arsenic oxide ( Sb2 ㅐ 4), zinc oxide (ZnO), tin oxide (ZnO2), cerium oxide (CeO2), tungsten oxide (WO3), and iron oxide (Fe2O3) are known, but titanium dioxide is generally the most widely used.
이산화티탄은 약3.2eV의 밴드캡 에너지를 가지는데 이에 해당하는 자외선이 입사되면 전자가 전도되어 여기되면서 전자와정공이 쌍을 형성하게 되고 이때 형성된 전자와 정공은 과촉매에 흡착되어 있는 산소나 물과 반응하여 OH나 O2와 같은 활성산소를 발생시키며 발생된 활성산소는 산화력이 매우 높은 물질로서 이산화티타늄 표면에 존재하다가 공기중에 포함된 세균의 살균작용과 유기화합물등과 접촉하게되면 이를 산화 시켜 물이나 이산화탄소로 분해하므로써 오염물질 제거와 공기정화가 이루어 지며 광화학 반응을 일으키지 않는 무기물은 이산회티탄이 가지는 초 친수성에 의해 표면에 쉽게 달라붙지 않게 하거나 달라붙더라도 바람에의해 쉽게 제거되게 한다.Titanium dioxide has a band cap energy of about 3.2 eV, and when ultraviolet rays are incident, electrons are excited and excited, forming electrons and holes paired. The formed electrons and holes are oxygen or water adsorbed on the overcatalyst. Reacts with and generates active oxygen such as OH or O2. The generated oxygen is very oxidizing and exists on the surface of titanium dioxide. When it comes into contact with the bactericidal action and organic compounds in the air, it oxidizes water. However, by decomposing to carbon dioxide, pollutants are removed and air purification is performed. Inorganic materials that do not cause photochemical reactions are easily removed by wind even if they are not easily adhered to the surface by the superhydrophilic property of titanium dioxide.
이하에서 본 발명의 바람직한 실시 예에 대하여 첨부된 도면을 참조하여 상세하게 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도1은 터널 내부 완성면에 광촉매를 코팅하는 정면도이고 도2는 지하차도 내부에 광촉매를 코팅하는 정면도이다1 is a front view of coating a photocatalyst on the finished surface inside the tunnel and FIG. 2 is a front view of coating a photocatalyst inside the underground roadway.
광촉매제를 물체의 표면에 코팅하는 방법은 스프레이법, 함침법 또는 딥코팅(DIP-COATING)법과 같은 다양한 방법과 광촉매막을 형성후 열처리 또는 열풍건조하여 코팅된막을 건고히 할수 있으므로 구조물내부의 특수성을 고려하여 하여야 한다.The method of coating the photocatalyst on the surface of an object is characterized by various methods such as spray method, impregnation method, or dip coating method, and drying the coated film by heat treatment or hot air drying after forming the photocatalyst film. Should be taken into account.
본발명에서는 이산화티탄을 함유한 졸상의 액체를 구조물 내부에 분사하고 내부의 특수성을 고려하여 코팅된막을 견고히 할 수 있도록 열풍건조를 하는 것이 바람직할것으로 판단된다In the present invention, it is preferable to spray hot air dry to inject the sol-like liquid containing titanium dioxide into the structure and to solidify the coated film in consideration of the specificity of the inside.
도로 구조물의 시공단계에서 본발명의 코팅작업을 수행할수도 있으며 이미 시공된 구조물일지라도 그표면을 청소후 스프레이 방법으로 간편히 코팅작업을 할 수 있다. The coating work of the present invention can be carried out at the construction stage of the road structure, and even the already constructed structure can be easily coated by spraying after cleaning the surface.
이상에서 설명한 바와 같이 본 발명 광촉매를 코팅한 도로 구조물(터널,지하차도 내부)은 단순한 코팅작업만으로 구조물내부의 조명에 의한 광촉매 작용으로 대기오염물질중 부착력이 강한 유기 물질은 분해하고 부유분진중 무기물은 표면과의 접착성을 떨어뜨리는 초친수성으로 구조물 내부의 환기풍, 자연풍, 차량주행풍에 의하여 쉽게 제거될수 있게하여 자동차의 배기가스와 매연등에 의하여 오염되는 도로구조물(터널,지하차도)내부를 깨끗이 유지할 수 있게하며 자동차 배출가스중 유해가스를 분해하는 공기정화 및 환기시설물의 규모 축소에 따른 터널 및 지하차도 공사비 절감에도 기여할 수 있게하는 효과가 있다.As described above, the road structure (tunnel, underground roadway) coated with the photocatalyst of the present invention decomposes organic substances having strong adhesion in air pollutants by photocatalytic action by lighting inside the structure with only a simple coating operation, and inorganic substances in suspended dust. Super hydrophilicity that reduces the adhesion to the surface makes it easy to remove by the ventilation wind, natural wind, and vehicle driving wind inside the structure to clean the inside of road structures (tunnels and underground roads) polluted by exhaust gases and soot It is possible to maintain and to contribute to the reduction of construction costs in tunnels and underground cars due to the reduction of air purification and ventilation facilities that decompose harmful gases in automobile emissions.
