Description
본 발명은 실내 공간의 공기 정화에 관한 것으로, 특히 이산화티탄(TiO2)을 이용한 물리적 방법으로 공기 중의 냄새 성분을 분해하고, 공기 중의 균 등을 살균시켜 줌으로 해서 공기를 정화시키는 것에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to air purification of indoor spaces, and more particularly, to purifying air by decomposing odor components in air by sterilizing airborne bacteria and the like by a physical method using titanium dioxide (TiO 2 ).
종래의 방법으로는 활성탄 등을 이용 이것들이 갖는 미세구조 (Micro Pore)의 모세관에 의해 냄새 분사를 흡착시키는 방법 등이 있었으며 시설 초기에는 냄새 제거가 가능하나, micro pore에 냄새 분자가 가득 차면 더 이상 냄새 분자를 흡착시키지 못하는 단점이 있어 자주 활성탄을 교환해 주어야 하는 번거로움과 그로 인한 유지비가 많이 든다는 단점을 갖고 있었다.Conventional methods include using activated carbon to adsorb odor jets by the micropore capillaries. These can be eliminated at the beginning of the facility, but once the micro pores are full of odor molecules, It has the disadvantage that it can not adsorb the odor molecules and has the disadvantage that the need to change the activated carbon frequently and the maintenance cost is high.
또한 주택 실내에 촛불, 가스 불꽃 등을 이용 공기 중의 냄새 분자를 태우는 방법 등이 있는데 이것 역시 작업 과정이 번거롭고, 화재 및 실내 온도조절 등에 문제점을 내포하고 있다.In addition, there are methods for burning odor molecules in the air by using candles, gas flames, etc., which are cumbersome in the process of work, and include problems such as fire and room temperature control.
또 오존 등에 의한 공기 산화법, 향수 등을 이용 실내 악취 등을 마스킹 시키는 방법 등이 있으나, 관리 유지비나 일시적인 냄새 제거 방법일 뿐 영구적 방법은 아닌 것으로 알려지고 있다.In addition, there is a method of masking indoor odors using air oxidation by ozone, perfume, etc., but it is known that it is not a permanent method but a maintenance maintenance fee or a temporary odor removal method.
본 발명에서는 이산화티탄(광촉매)이 빛을 받아 전위를 일으켜 그 전위 차에 의해 공기 중의 항균(抗菌), 탈취(脫臭) 등의 기능을 갖고 있는 것으로 알려지고 있다. 그 예로서 MRSA(황색 포도상 구균)가 병원 내에 감염되어 인명에 손상시키는데 병원내 감염을 막기 위해 TiO2가 함유된 타일을 제조하여 병원내 벽, 바닥 등에 시공하여 MRSA균 번식을 억제했다는 보고가 되어지고 있다.1)이 방법은 타열에 광촉매를 코팅시킨 것으로 광촉매(TiO2)을 분말 그대로 코팅이 안되고 TiO2를 겔-졸 법에 의해 액상으로 코팅시키므로 많은 코팅 비용이 소모되고 타일이라는 세라믹 위에 코팅하므로 monolayer상으로 코팅되므로 광촉매의 비표면적이 작아 촉매 기능(냄새, 항균…)이 미약하다는 결점을 갖고 있다. 또 TiO2와 활성탄 등의 흡착제와 섞어서 부직포 중에 봉입시켜 탈취를 시도2)하는 보고 등이 있다. 이 방법 역시 TiO2가 다공성 활성탄 틈에 끼어 빛을 받을 수 없어 광반응이 일어나지 않아 단순 활성탄에 의한 탈취, 항균 수준의 기능만 나타내고 있다. 이와 같은 TiO2에 실내 공간의 미약한 자외선이 에너지 적으로는 미약하지만, 그 光子 하나 하나가 갖고 있는 에너지는 높아, 400nm의 광자가 갖는 에너지는, 열에너지로 환산하면 30,000℃에 이르기 때문에, 光에너지가 낮은 경우에도 분해 대상물에 탈취, 항균 등 적용이 가능하다 보고되고 있다.In the present invention, titanium dioxide (photocatalyst) is known to have a function such as antibacterial and deodorization in the air due to the potential difference caused by light. For example, MRSA (yellow staphylococcus aureus) is infected in hospitals and damages human lives. To prevent infection in hospitals, tiles containing TiO 2 were manufactured and applied to walls and floors in hospitals to suppress MRSA growth. ought. 1) This method is another column designed is that the powder as coated with the photocatalyst (TiO 2) was coated with the photocatalyst of TiO 2 gel-consumes a lot of coating costs because coating the liquid phase by a sol method is coated on a ceramic of tiles monolayer onto Since the specific surface area of the photocatalyst is small, the catalyst function (odor, antibacterial…) is weak. In addition mixed with an adsorbent such as activated carbon and TiO 2 and the like to see that the deodorizing 2) attempts to sealed in a nonwoven fabric. This method also shows only the function of deodorization and antibacterial activity by simple activated carbon because TiO 2 is not caught in the gap of porous activated carbon and cannot receive light. Although the weak ultraviolet light in the interior space is weak in terms of energy such as TiO 2 , the energy of each one of the photons is high, and the energy of the photon of 400 nm reaches 30,000 ° C. in terms of thermal energy. It is reported that even if the low deodorization, antibacterial, etc. can be applied to the decomposition target.
한편 최근 들어 주거 생활수준의 향상과 더불어, 실내의 환경 문제가 주목되어 지고 있다. 그러므로 인간 생활에서 발생하는 냄새, 특히 신건축의 보급과 더불어 이것에서 발산하는 化學物質(접착제 냄새, …), 기름냄새, 세균등 저농도 이지만 이러한 오염 물질의 제거가 절실히 요구되어지고 있다. 또한 지하에 설치된 실내 공간에서는 이와 같은 냄새 제거, 세균 제거 등이 더욱더 요구되어 지고 있는 실정이다. 그래서 본 발명에서는 에너지가 적게 들면서 물리적인 방법으로 이와 같은 문제점을 해소시킬 수 있는 방법으로 광촉매(이산화티탄)를 이용하여 탈취, 항균 용도로 사용하고자 한다.On the other hand, in recent years, with the improvement of the living standard of living, indoor environmental problems have been attracting attention. Therefore, in addition to the spread of odors, especially new buildings, which occur in human life, such as chemical substances (adhesive odor, etc.), oil odors, bacteria, etc., the removal of these pollutants is urgently required. In addition, in the indoor space installed underground, such an odor removal, bacteria removal, etc. are increasingly required. Therefore, the present invention intends to use the photocatalyst (titanium dioxide) for deodorization and antibacterial use as a method that can solve such a problem by physical method while using less energy.
좀 더 자세히 광촉매를 이용한 부분을 언급한다면 광촉매 표면을 micro leve1로 제어하여, 촉매 표면적을 크게 하여 줌으로 해서 해서 촉매 활성이 높은 광촉매 제작이 가능하여질 것으로 생각되어져, 실리카 matrix를 micro level로 多孔質化하기 위해 티탄 아르코시드를 이용해 겔-졸 반응 용액계에 유리 상에 코팅 시킨 후, 피박을 만든 후 이것을 소성 함으로 해서 다공질 TiO2박막이 만들어지는데 이때 상대 습도를 10% 이하로 유지하여야 하며, 끌어올리는 속도를 조절할 수 있어야 하며 dip용액으로부터 유리기판을 끌어올리면 티탄 알코시드가는 백색 불투명으로 되어지지 않고 투명한 박막으로 형성되어 진다.If the photocatalyst is used in more detail, it is thought that the photocatalyst surface can be controlled by micro leve1 and the catalyst surface area can be increased to enable the production of photocatalyst with high catalytic activity. For the sake of chemistry, a film of gel-sol reaction solution was coated on the glass using titanium arcoside, and then a film was formed and then fired to form a porous TiO 2 thin film. The relative humidity should be kept below 10%. It should be able to control the raising speed, and when the glass substrate is pulled up from the dip solution, the titanium alkoxide is formed into a transparent thin film instead of becoming white opaque.
이와 같이 만들어진 투명한 광촉매는 여러 방면에 널리 사용되어질 것이다.The transparent photocatalyst made in this way will be widely used in various fields.
본 발명의 첫 번째 목적을 광촉매(이산화티탄)을 벽지, 커튼 또는 액자의 유리 부분에 박막 또는 분말을 코팅시켜, 태양 광선 및 형광등 등 실내 빛을 이용하여 실내 공기 중에 함유되어 있는 냄새 성분 및 균 등이 광촉매에 닿는 순간 빛에 의한 에너지를 이용 산화 반응을 일으켜 냄새 분자는 파괴되고, 균등은 산화 반응을 일으켜 살균 되어지는 성질을 이용한 것이다.The first object of the present invention is a photocatalyst (titanium dioxide) by coating a thin film or powder on the glass portion of the wallpaper, curtain or frame, odor components and bacteria contained in the indoor air using indoor light such as sunlight and fluorescent lights When the photocatalyst is touched, it uses the energy of light to cause an oxidation reaction, odor molecules are destroyed, and evenly, an oxidation reaction is used to sterilize.
좀 더 자세한 설명을 하면 앞에서 언급한 바와 같이 티탄 아르코시드를 이용 액자, 거울 등 유리 표면에 투명 박막으로 코팅시켜 이것을 550℃이상으로 열처리 시켜 이산화티탄의 구조가 아나타제 상태로 한 뒤 상온으로 냉각시킨 후 사용한다.To explain in more detail, as mentioned above, use titanium arcoside to coat a glass surface such as a frame or mirror with a transparent thin film and heat-treat it to 550 ℃ or higher to make the structure of titanium dioxide anatase and then cool it to room temperature. use.
또 벽지나 커텐지에는 광촉매(이산화티탄) 미분말을 PVA 또는 아크릴 에멀죤 수지 등과 같이 표면에 뿌려주어, 벽지나 커텐지 표면에 코팅시키는 방법 또는 PVA 옅은 농도의 용액에 분산시킨 후 커텐지나 벽지를 침지법으로 광촉매를 고착시키는 방법 등을 이용하여 벽지나 커텐지 표면에 광촉매를 고정화 시킨후 사용 하였다. 이렇게 만든 광촉매가 고정화된 시편을 가지고 냄새 성분이 제거되고 정도를 측정하기 위하여 밀폐된 아크릴 상자(52.5cm×10cm×12cm)를 만든 후 그 속에 작은 전동 팬을 붙여 밀폐된 상자 속의 공기대류가 균일하게 잘 일어나도록 하였다. 또한 밀폐된 상자 중앙 부분에 파이렉스 유리관(ø35mm)을 관통시켰다. 그 관통시킨 Pyrex 유리관 속에 ø32mm 길이 525mm, 20W 형광등 삽입, 광반응의 광원으로 사용했다.In the case of wallpaper or curtain, the photocatalyst (titanium dioxide) powder is sprayed on the surface such as PVA or acrylic emulsion resin and coated on the surface of the wallpaper or curtain, or dispersed in a PVA light solution, and then the curtain or wallpaper is immersed. The photocatalyst was used after fixing the photocatalyst on the surface of the wallpaper or the curtain using a method of fixing the photocatalyst by the method. The photocatalyst made in this way has an immobilized specimen to remove the odor and to measure the degree. The sealed acrylic box (52.5cm × 10cm × 12cm) is made and a small electric fan is attached to it so that the air convection in the sealed box is uniform. I got up well. In addition, a Pyrex glass tube (ø35mm) was penetrated through the center of the sealed box. The penetrated Pyrex glass tube was used as a light source for ø32mm length 525mm length, 20W fluorescent lamp insertion and photoreaction.
또 밀폐된 상자 속에 광촉매를 코팅시킨 벽지(가로 9.8cm×세로 40cm)의 시편을 만든 후 광촉매가 코팅된 부분이 형광등 빚을 받을 수 있도록 놓았다. 그 후 신축 가옥 등에서 대표적으로 많이 발생하는 포르말린 냄새를 만들기 위해 35% 포름알데하이드 용액에 공기를 불어 넣어 포르말린 냄새를 만든 후 밀폐된 상자 속에 주입시킨 후 다시 외부와 차단되게 밀폐시켰다. 외부 빛도 차단되게 상자 외부를 빛 차단 포장지로 포장했다. 이 때 밀폐된 상자 내의 체적은 5178㎠이였으며, 시편 벽지에 살포된 광촉매의 도포량은 0.63g, 그러므로 단위 면적당 이산화티탄(광촉매)도포량은 1.6×10-3g/㎤이었다.In addition, specimens of photocatalyst coated wallpaper (9.8 cm x 40 cm) were made in an airtight box and the photocatalyst coated sections were placed to receive fluorescent light. After that, in order to make formalin odor, which is typically generated in new houses, air was blown into a 35% formaldehyde solution to make a formalin odor, and then injected into an airtight box, and then sealed again to be blocked from the outside. The outside of the box was packed with light blocking wrapper to block external light. At this time, the volume in the sealed box was 5178 cm 2, and the coating amount of the photocatalyst sprayed on the specimen wallpaper was 0.63 g, and therefore the amount of titanium dioxide (photocatalyst) coating per unit area was 1.6 × 10 −3 g / cm 3.
이렇게 하여 만든 장치에 포르말린 냄새가 제거되는 정도를 측정하기 위해 포르말린 냄새 농도의 감소량을 가스 크로마토그래피(G.C)을 사용하였다.Gas chromatography (G.C) was used to reduce the amount of formalin odor concentration in order to measure the degree of formalin odor removal in the device thus made.
포르말린 냄새 농도를 측정하기 위해 GC, Detection: FID, column : DB-5, Temp. (oven : 100℃, Detection : 120℃, injection : 120℃), Carrier Gas : He (30㎖/min), 주연소 가스 : H2 (30㎖/min), 조연소 가스 : Air(300㎖/min)으로 하여 검토하였다.To determine formalin odor concentration, GC, Detection: FID, column: DB-5, Temp. (oven: 100 ℃, Detection: 120 ℃, injection: 120 ℃), Carrier Gas: He (30mL / min), Main Combustion Gas: H2 (30mL / min), Crude Gas: Air (300mL / min Was examined.
그 결과 포르말린 가스 농도는 갓 주입 후 0.84분 후에 단일 peak로 나타내었다.(그림 1 참조)As a result, formalin gas concentration was shown as a single peak 0.84 minutes after fresh injection (see Figure 1).
그리하여 본 실험에서는 시간의 경과에 따른, 포르말린 농도 감소를 검토하였다.Thus, in this experiment, the decrease in formalin concentration over time was examined.
그 결과 광반응 290분만에 포르말린 초기 농도의 10%가 감소되는 결과를 얻을 수 있었다.(그림 2 참조)The result was a 10% reduction in the initial formalin concentration in 290 minutes of photoreaction (see Figure 2).
이러한 방법으로 암모니아, 담배, 유화수소, 및 김치 냄새 등과 같은 냄새 성분의 감소량을 검토하였다.In this way, the amount of reduction of odor components such as ammonia, tobacco, hydrogen sulfide, and kimchi odor was examined.
또한 벽지 대신, 광촉매가 코팅된 유리, 커텐지 등도 같은 실험을 반복하여 실험하였다.In addition, instead of the wallpaper, the photocatalyst-coated glass, curtain, and the like were repeated and tested.
