Abstract
Description
본 발명의 실시예는 공기 청정 기술과 관련된다. Embodiments of the invention relate to air cleaning techniques.
기존의 에어 클리너 제품은 음이온 방식과 필터 방식이 있다. Conventional air cleaner products have anion type and filter type.
이 중 음이온 방식은 고전압의 전류로 음이온을 방출하여 공기중의 유해물질과 결합하여 미세먼지를 제거한다. 그러나 음이온 발생 공기청정기는 필연적으로 오존이 발생하게 되는데 과다할 경우 호흡기 질환에 해를 끼칠 수 있게 된다. Among them, the negative ion method emits negative ions with high voltage current and combines with harmful substances in the air to remove fine dust. However, anion-generating air purifiers inevitably cause ozone, which, if excessive, can harm respiratory diseases.
그리고, 필터 방식은 오염된 공기를 팬으로 흡입하고, 필터에 의해 미세한 먼지나 세균류를 집진하며, 이를 통해 체취나 담배 냄새를 탈취한다. 또한, 필터방식의 주요 구성은 프리필터와 헤파필터의 이중 구조로 되어 있어 이 필터들이 미세먼지를 제거해준다. 헤파필터의 특성을 보면 미세 먼지의 경우 0.3μm 정도의 미세먼지를 제거해 준다. 그러나 이러한 필터방식은 잦은 필터 청소 및 교체를 필요로 하며, 만일 필터교체 시기를 놓치면 포집된 세균이 오히려 번식되어 인체에 더 해로울 수가 있으며 0.3μm 보다 더 작은 초미세먼지는 제거하지 못한다는 단점이 있다. 또한 최근 일부 제품에서 OIT가 검출되어 사회적 문제가 되기도 하였다. The filter system sucks the contaminated air into the fan, collects fine dust or bacteria by the filter, and thereby smells the body odor or the smell of the cigarette. Also, the main structure of the filter system is a dual structure of a pre-filter and a HEPA filter, and these filters remove fine dust. The characteristic of the HEPA filter removes fine dust of 0.3 μm in the case of fine dust. However, this type of filter requires frequent filter cleaning and replacement. If the filter replacement timing is missed, the collected germs may reproduce rather harmful to the human body, and the ultrafine dust smaller than 0.3 μm can not be removed . In addition, OIT has recently been detected in some products, which has become a social problem.
최근에는 광촉매 산화 반응을 이용한 필터가 연구되고 있으나, 광촉매를 이용하여 활발한 산화 반응을 일으키기 위해서는 많은 양의 TiO2(이산화티타늄)이 필요하다는 문제점이 있다.Recently, a filter using a photocatalytic oxidation reaction has been studied, but a large amount of TiO2 (titanium dioxide) is required to cause an active oxidation reaction using a photocatalyst.
본 발명의 실시예는 기존과 상이한 에어 클리너 장치를 제공하기 위한 것이다. An embodiment of the present invention is to provide an air cleaner apparatus different from the conventional one.

The effect of temperature The effect of temperature
Since the Product is intended for cleaning indoor air where the people work, the working environment temperature range can be in the range of +5 to +40 ℃. Considering that all the tests of the Product were carried out at a temperature of about 25 ℃, the change in the speed of chemical reactions, estimated from the Arrhenius equation with activationenergy Ea reactions = 10 J / mol, may be:Since the product is intended for cleaning indoor air where the people work, the working environment temperature range can be in the range of +5 to +40 ℃. Ea reactions = 10 J / mol, may be: The reaction was carried out at a temperature of about 25 ° C,
a decrease of 1.1 times with decreasing temperature on +5 ℃; increasing in 1.3-fold with increasing temperature up to 40 ℃. a decrease of 1.1 times with decreasing temperature on + 5 ° C; increasing in 1.3-fold with increasing temperature up to 40 ° C.
Temperature also affects the intensity of UV radiation of ultraviolet lamps. It may be reduced by about 1% at every temperature deviation 1.5 ℃ from a nominal operating temperature. The nominal operating temperature of the lamps is about 20 ℃. This means that the rate of catalytic reactions can be reduced to approximately 1.1 times at 5 ℃ and 1.15 times at 40 ℃.Temperature also affects the intensity of ultraviolet lamps. It may be reduced by about 1% at every temperature deviation of 1.5 ° C from a nominal operating temperature. The nominal operating temperature of the lamps is about 20 ° C. This means that the rate of catalytic reactions can be reduced to approximately 1.1 times at 5 ° C and 1.15 times at 40 ° C.
As a result, estimates indicate that with reducing the temperature to 5 ℃ rate of catalytic reactions can be reduced by about 20%, and with increasing to + 40 ℃ if it will grow, but slightly - by 13-15%As a result, estimates show that with the reduction in temperature to 5 ° C, the rate of catalytic reactions can be reduced by about 20%

Effect of dustEffect of dust
The presence of dust of different origin in the air space does not have a significant impact on the functioning of the photocatalytic air purification systems of the Product due to presence of electronic wind module. At the same time, in special environments of using the Product: at the excess of dust concentration of 550-600 mg / m3 and the simultaneous presence in dust of the conductive materials (such as graphite or fine metallic dust) dramatically increases the probability of the formation of the breakdown of the air space between the electrodes of an electrostatic precipitator, that is short-circuited. But due to the presence in the Product protection system against short circuit its operation under these conditions is not possibleThe presence of dust in the air space does not have a significant impact on the functioning of the photocatalytic air purification systems.
