본 발명은 유해물질 제거장치에 관한 것으로, 더욱 상세하게는 광촉매 특성을 가지는 나노입자를 생성하는 나노입자 생성장치와 상기 나노입자를 활성화시키는 활성부를 이용하여 유해물질을 제거할 수 있는 유해물질 제거장치에 관한 것이다.The present invention relates to an apparatus for removing toxic substances, and more particularly, a toxic substance removing apparatus capable of removing toxic substances by using a nanoparticle generating apparatus for generating nanoparticles having photocatalytic properties and an active part for activating the nanoparticles. It is about.

현대사회는 환경오염에 의해 생활환경이 점차 악화되고 있다. 이러한 환경 오염은 사람들이 거주하는 실내환경의 악화로 이어지고 있으며, 유해한 휘발성 유기물질(VOC: Volatile Organic Compounds)이나 미세먼지, 악취, 병원균 등에 의한 위험에 항시 노출되어 있다. In modern society, living environment is getting worse due to environmental pollution. Such environmental pollution leads to deterioration of the indoor environment where people live, and is always exposed to the dangers of harmful volatile organic compounds (VOCs), fine dust, odors and pathogens.

상기와 같은 유해물질을 제거하기 위하여 일반적으로 사용되는 유해물질 제거장치는 공기유로가 형성된 덕트 내부에 공기 유동을 발생시키는 송풍팬과 산화티타늄 또는 제올라이트에 산화티타늄을 혼합한 혼합물을 첨가한 광촉매필터와 자외선을 발생시키는 광원을 설치하여 구성되었다. In order to remove such harmful substances, the apparatus for removing harmful substances generally includes a photocatalyst filter comprising a mixture of a blowing fan and a titanium oxide or a mixture of titanium oxide and zeolite that generates air flow in a duct in which an air flow path is formed; It was comprised by installing the light source which generate an ultraviolet-ray.

이와 같은 유해물질 제거장치에 송풍팬과 자외선을 발생시키는 광원을 작동하면 미생물을 포함한 먼지 등의 이물질이 상기 광촉매필터에 걸러지면서 퇴적되고, 상기 광촉매필터에 걸러진 유해물질은 자외선에 의해 활성화된 산화티타늄에 의해 살균되거나 분해됨으로써 유해물질이 제거된다.When a fan and a light source for generating ultraviolet rays are operated in the apparatus for removing the harmful substances, foreign substances such as dust including microorganisms are filtered and deposited on the photocatalyst filter, and the harmful substances filtered through the photocatalyst filter are titanium oxide activated by ultraviolet rays. Hazardous substances are removed by sterilization or decomposition.

그러나, 산화티타늄과 같이 광촉매 특성을 나타내는 물질(이하 "광촉매물질" 이라 함)이 필터에 첨가되어 있으므로 광촉매물질이 활성화되는 부위가 필터 표면에 한정되므로 상기 필터에 직접 접촉하는 이물질에 포함된 유해물질만이 제거되었다. 특히, 상기 필터 표면에 다량의 이물질이 퇴적되면 광원에 의해 광촉매 특성을 가지는 물질의 활성화가 어렵게 되며, 덕트 내부의 유속이 빠를 경우 광촉매물질에 의해 유해물질이 제거되지 못하고 실내로 유입되는 문제점이 있었다.However, since a substance exhibiting photocatalytic properties such as titanium oxide (hereinafter referred to as "photocatalytic material") is added to the filter, the hazardous substance contained in the foreign matter directly contacting the filter because the site where the photocatalytic material is activated is limited to the filter surface. Only was removed. In particular, when a large amount of foreign matter is deposited on the surface of the filter, it is difficult to activate a material having a photocatalytic property by a light source, and when the flow rate inside the duct is fast, harmful substances cannot be removed by the photocatalytic material and flow into the room. .

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 본 발명의 목적은 유해물질과 광촉매물질이 충분히 반응할 수 있도록 하여 유해물질의 제거 효율을 높일 수 있는 유해물질 제거장치를 제공하는 것이다.The present invention is to solve the above problems, it is an object of the present invention to provide an apparatus for removing harmful substances that can sufficiently react the harmful substances and photocatalyst substances to increase the removal efficiency of the hazardous substances.

The nanoparticle generator 20 is to produce titanium nanoparticles (TiO 2 ) nanoparticles known as photocatalyst material or composite nanoparticles in which metal (Ag, Fe, W, Cr) is added to the titanium dioxide (TiO 2 ). desirable. In addition, the nanoparticle generating apparatus 20 uses a heating type or a material that generates nanoparticles by locally heating and vaporizing the material as an electrode, and generates a spark discharge between both electrodes to vaporize the material. It can be formed in various ways, such as a discharge type to generate particles, a spray method to be mixed and sprayed in the liquid phase.

광촉매물질인 이산화티탄(TiO2)이 그 입자크기가 20nm 이하인 나노입자로 되면 매우 독특한 성질이 나타내는데, 태양광이나 형광등에서 발생되는 400nm이하의 자외선을 받으면 이 입자들은 유기물 분해기능, 항균.살균기능, 친수(hydrophilic)기능에 의한 자정(self-cleaning)효과 및 김서림방지 효과를 갖게 된다. 이러한 기능 및 효과는 건축자재, 공기정화, 항균 살균 제품, 도로자재, 자동차, 폐수처리 등에 응용할 수 있으며 특히, 상기와 같이 덕트 내부에서 유동하는 공기에 사용할 경우 에어컨, 공기청정기, 청소기, 공조 덕트 등에 사용할 수 있다.When titanium dioxide (TiO 2 ), a photocatalytic material, becomes nanoparticles with a particle size of 20 nm or less, it exhibits a very unique property.

또한, 나노입자 생성장치(20)와 집진장치(40)가 소정거리 이격되어 설치되고 그 사이에 활성부(30)가 설치됨으로써, 나노입자가 공기와 함께 흘러가면서 반응이 이루어지므로 반응시간을 증가시킬 수 있으므로, 반응시간에 민감한 미생물이나 유해가스의 제거효율을 극대화할 수 있다. 만일 유해물질이 집진장치(40)까지 흘러가는 동안 나노입자와 반응하지 못했다고 해도, 집진장치(40)에 걸러진 유해물질 위로 나노입자가 계속해서 뿌려지므로 유해물질의 제거효율을 더욱 높일 수 있다. In addition, since the nanoparticle generator 20 and the dust collector 40 are installed at a predetermined distance apart from each other, and the active part 30 is installed therebetween, the reaction time is increased because the nanoparticles flow with the air, thereby increasing the reaction time. Since it can be, it is possible to maximize the removal efficiency of microorganisms or harmful gases sensitive to the reaction time. If the harmful substances do not react with the nanoparticles while flowing to the dust collector 40, the nanoparticles are continuously sprayed over the harmful substances filtered by the dust collector 40, thereby further increasing the removal efficiency of the hazardous substances.
