Description

바이러스 제거 공기정화장치{Virus Removal Air Clean System}Virus Removal Air Clean System

본 발명은 공기정화장치에 관한 것으로, 특히 오염된 공기 중의 바이러스균의 살균, 탈취, 정화하기 위한 바이러스 제거 공기정화장치에 관한 것이다.The present invention relates to an air purifier, and more particularly, to a virus removal air purifier for sterilizing, deodorizing and purifying virus bacteria in polluted air.

공간에 부유하는 곰팡이균, 바이러스균등의 살균(UV-C 파장)을 조사하여 살균하는 것은 널리 알려져있다. It is widely known to sterilize by irradiating sterilization (UV-C wavelength) of mold, virus, etc. floating in space.

그러나 단파장의 자외선을 공기중에 조사하는 것은 이 대상으로 하는 균이 가시화할 수 없기 때문에 그 범위를 특정하지 못하고, 또한 인간의 건강에 미치는 영향도 보장, 확립되어 있지 않다.However, when short-wavelength ultraviolet rays are irradiated into the air, the scope cannot be specified because the target bacteria cannot be visualized, and the effect on human health is not guaranteed or established.

한편 HEPA류의 필터 등으로 공기를 통과시키는 것은 0.3μm 이하의 미세물질을 제거할 수 없다.On the other hand, passing air through a HEPA-type filter, etc. cannot remove fine substances of 0.3 μm or less.

이를 보완하기 위해 이산화티타늄, 은 등을 사용한 광촉매를 이용한 필터에 의한 탈취, 살균 효과는 알려져 있지만 이산화티타늄의 밴드갭은 약 3 eV보다 크기 때문에 태양과 블랙라이트 등 자외선을 많이 포함한 큰 에너지의 빛을 조사하면 항균효과가 크지만, 빛이 없는 곳에서는 작용하지 않고, 또 형광등 등 약한 빛에서는 그 항균력이 약하다.To compensate for this, the deodorization and sterilization effect of a filter using a photocatalyst using titanium dioxide and silver is known, but the band gap of titanium dioxide is larger than about 3 eV, so it can absorb high energy light including a lot of ultraviolet rays such as the sun and black light. Although the antibacterial effect is great when irradiated, it does not work in the absence of light, and the antibacterial effect is weak in weak light such as a fluorescent lamp.
