도 1에서, 오염된 공기(A)가 부직포필터 또는 헤파필터(B)를 통과하면서 분진이 제거되고, Ti-Mn-Mg 복합금속 촉매를 코팅한 입상 활성탄필터 또는 섬유상 활성탄 필터층(C)를 통과한후 형광등 또는 LED(발광다이오드) 램프(D)를 통과후, 다 시 Ti-Mn-Mg 복합금속 촉매가 코팅된 입상 활성탄필터 또는 섬유상 활성탄 필터층(E)을 통과하고, 흡입팬(F)을 통과하여 미세분진이 제거되고, 휘발성유기화합물과 포름알데히드는 이산화탄소와 물로 바뀌며, 바이러스와 박테리아가 살균되어 깨끗한 공기(G)로 변하게 된다.1, dust is removed while the contaminated air (A) passes through the nonwoven filter or the hepa filter (B), and passes through the granular activated carbon filter or the fibrous activated carbon filter layer (C) coated with the Ti-Mn-Mg composite metal catalyst. After passing through a fluorescent lamp or LED (light emitting diode) lamp (D), and then again passed through a granular activated carbon filter or a fibrous activated carbon filter layer (E) coated with a Ti-Mn-Mg composite metal catalyst, the suction fan (F) Through this, fine dust is removed, volatile organic compounds and formaldehyde are converted into carbon dioxide and water, and viruses and bacteria are sterilized and converted into clean air (G).
종래의 공기청정기 또는 공기청정 시스템은 헤파필터, 입상활성탄 필터를 사용하여 분진만을 제거하는 형태가 주류를 이루었는데, 이것은 분진외에 휘발성유기화합물이나 포름알데히드등의 새집증후군을 일으키는 물질이나 바이러스, 박테리아등에 대한 항균, 살균 기능이 없었다. 다른 방법으로는 플라즈마 방전을 일으켜 분진을 제거하는 방법이 있는데, 이것은 플라즈마 방전시 오존이 발생하여 유해한 공기를 만들어낸다. 최근에는 자외선에서 작용하는 광촉매를 첨가하여 사용하는 경향이 있는데, 이방법도 자외선등을 사용하므로 오존이 발생하여 유해한 공기를 발생시키고 있다.Conventional air purifiers or air cleaning systems use the HEPA filter and granular activated carbon filter to remove dust only, which is mainly caused by substances, viruses, bacteria, etc. that cause sick house syndrome such as volatile organic compounds and formaldehyde. There was no antibacterial, antiseptic function. Another method is to generate plasma discharge to remove dust, which causes ozone to be generated during plasma discharge, creating harmful air. Recently, there is a tendency to add and use a photocatalyst acting in ultraviolet light, this method also uses ultraviolet light, so ozone is generated to generate harmful air.
본 발명에서는 종래의 기술에 나타난 단점들을 제거하여, 오존의 발생이 없이 분진과 휘발성유기화합물, 포름알데히드를 제거하고, 항균, 살균 기능을 하여 깨끗한 공기로 정화하는 가시광촉매 및 장치를 제공하는데 있다.The present invention is to remove the disadvantages shown in the prior art, to remove the dust and volatile organic compounds, formaldehyde without the generation of ozone, and to provide a visible photocatalyst and apparatus for purifying clean air by antibacterial, sterilizing function.
본 발명에 사용되는 가시광촉매는 TiO2 분말에 망간 금속으로써 망간나이트레이트와 마그네슘 금속으로써 마그네슘나이트레이트를 함침시켜 110℃에서 6시간 이상 건조시킨후 300℃ ∼ 500℃ 사이에서 3시간 이상 소성하여 Ti-Mn-Mg 복합금속 촉매를 만들거나, Ti 금속으로써 TiCl4 또는 티타늄테트라이소프로폭사이드와 망간 금속으로써 망간나이트레이트와 마그네슘금속으로써 마그네슘나이트레이트를 혼합하여 질산 또는 황산 또는 염산 수용액상에서 60℃ ∼ 150℃에서 60rpm 이상으로 교반하면서 졸겔법으로 제조하여 Ti-Mn-Mg 복합금속 촉매를 만든다. Ti-Mn-Mg 복합금속 촉매에 사용된 금속의 비율은 Ti : Mn + Mg = 100 : 1에서 1 : 1 의 무게비로 혼합하여 사용하며, Mn : Mg = 10 : 1에서 1:10의 무게비로 혼합하여 사용한다. 상기의 금속들간의 무게비를 벗어나게 되면 촉매표면에서 가시광 흡수도가 떨어져 가시광촉매의 효과가 현저히 떨어진다.The visible photocatalyst used in the present invention is impregnated with TiO 2 powder with manganese nitrate as a manganese metal and magnesium nitrate with magnesium metal, dried at 110 ° C. for at least 6 hours, and then calcined at 300 ° C. to 500 ° C. for at least 3 hours. -Mn-Mg composite metal catalyst, or TiCl 4 or titanium tetraisopropoxide as Ti metal and manganese nitrate as magnesium metal and magnesium nitrate as magnesium metal are mixed at 60 ° C. in an aqueous solution of nitric acid or sulfuric acid or hydrochloric acid. The Ti-Mn-Mg composite metal catalyst was prepared by sol-gel method while stirring at 150 ° C. or higher at 60 rpm or more. The ratio of the metal used in the Ti-Mn-Mg composite metal catalyst is used by mixing in a weight ratio of Ti: Mn + Mg = 100: 1 to 1: 1, and in a weight ratio of Mn: Mg = 10: 1 to 1:10. Use by mixing. When the weight ratio between the metals deviates, the absorbance of visible light is reduced at the surface of the catalyst, and the effect of the visible light catalyst is remarkably decreased.
그리고, 본발명에 사용되는 공기정화기는 도 1에서와 같이 오염된 공기(A)를 부직포 필터 또는 헤파필터(B)를 통과하면서 분진이 제거되고, Ti-Mn-Mg 복합금속 촉매를 코팅한 입상 활성탄필터 또는 섬유상 활성탄 필터층(C)를 통과한후, 형광등 또는 LED 램프(D)를 통과후, 다시 Ti-Mn-Mg 복합금속 촉매가 코팅된 입상 활성탄필터 또는 섬유상 활성탄 필터층(E)를 통과한후, 흡입팬(F)를 통과하여, 미세분진이 제거되고 휘발성유기화합물과 포름알데히드가 가시광촉매의 작용에 의해 이산화탄소와 물로 바뀌며, 바이러스와 박테리아가 살균되어 깨끗한 공기(G)로 변하게 된다. 입상활성탄 필터 또는 섬유상 활성탄 필터에 가시광촉매인 Ti-Mn-Mg 복합금속 촉매를 코팅하게 되면 휘발성 유기화합물이나 박테리아가 활성탄 필터에 흡착되었다가 표면에 코팅된 가시광촉매에 의해 형광등 불빛 또는 LED 불빛을 받아 광촉매 작용을 하여 휘발성 유기화합물이나 포름알데히드는 이산화타소와 물로 쉽게 분해시키고 박테리아나 바이러스는 살균이 된다.In addition, the air purifier used in the present invention removes dust while passing the contaminated air (A) through the nonwoven fabric filter or hepa filter (B) as shown in FIG. 1, and is coated with a Ti-Mn-Mg composite metal catalyst. After passing through activated carbon filter or fibrous activated carbon filter layer (C), passing through fluorescent lamp or LED lamp (D), and then passing through granular activated carbon filter or fibrous activated carbon filter layer (E) coated with Ti-Mn-Mg composite metal catalyst. After passing through the suction fan (F), fine dust is removed, the volatile organic compounds and formaldehyde are changed to carbon dioxide and water by the action of the visible photocatalyst, viruses and bacteria are sterilized and turned into clean air (G). When the Ti-Mn-Mg composite metal catalyst, which is a visible photocatalyst, is coated on a granular activated carbon filter or a fibrous activated carbon filter, volatile organic compounds or bacteria are adsorbed onto the activated carbon filter and then receive a fluorescent light or an LED light by the visible photocatalyst coated on the surface. By photocatalytic action, volatile organic compounds and formaldehyde are easily decomposed into titanium dioxide and water, and bacteria and viruses are sterilized.
