Description
본 고안은 공조기 또는 공기정화기 등에 설치되어 오염된 실내공기를 정화하는 필터장치에 관한 것으로, 특히 자외선램프와 광촉매가 코팅된 필터부재를 구비하여, 자외선램프 작동시 방사되는 자외선이 광촉매에 닿을 때 발생되는 광촉매반응으로 오염된 실내공기를 정화하는 광촉매식 필터장치에 관한 것이다.The present invention relates to a filter device for purifying contaminated indoor air installed in an air conditioner or an air purifier. In particular, the present invention includes a filter member coated with an ultraviolet lamp and a photocatalyst, and is generated when ultraviolet rays emitted during the operation of the ultraviolet lamp come into contact with the photocatalyst. The present invention relates to a photocatalyst filter device for purifying indoor air contaminated by photocatalytic reaction.
일반적으로 오염된 실내공기는 오염된 대기와 함께 인체에 치명적인 해를 입힌다. 즉, 주거양식의 변화로 인한 단열, 냉방, 방음 등의 효과를 높이기 위하여 밀폐도가 증가된 실내에서 거주하는 시간이 늘어날 뿐만 아니라, 오염된 대기의 경우에는 자연적으로 정화되는 비율이 큰 반면 실내공기는 한정된 공간에서 계속해서 순환하므로 오염된 대기보다 더 심각한 폐해를 가져다 줄 우려가 있다. 또한, 에너지 보존을 위한 새로운 건축자재의 등장으로 오염물질의 방출이 더욱 증가하는 추세이다.In general, contaminated indoor air, along with the contaminated atmosphere, is harmful to humans. In other words, in order to increase the effect of insulation, cooling, and soundproofing due to the change of residential style, not only the time of living in the room with increased airtightness is increased, but also the polluted atmosphere has a large rate of natural purification but As circulates continuously in confined spaces, there is a risk of causing more serious harm than polluted atmosphere. In addition, the emergence of new building materials for energy conservation is increasing the emission of pollutants.
이에, 근래에는 실내의 오염된 공기를 정화하여 신선한 공기를 배출하는 공기정화기의 사용이 증대되고 있는 실정이다.Therefore, in recent years, the use of an air purifier for purifying polluted air in the room and discharging fresh air is increasing.
이러한 공기정화기는 가정이나 사무실, 산업현장 등에서 발생되는 오염공기를 정화하기 위해 설치되는 것으로, 공기 유입구와 공기 배출구가 형성된 정화기 본체와, 정화기 본체 내에 다층으로 적재되어 공기 유입구를 통해 유입되는 공기를 여과하는 에어필터, 및 정화기 본체 내에 내장되어 외부의 공기를 정화기 본체 내로 유입한 후 에어필터에 의해 여과된 공기가 공기 배출구를 통해 실내로 배출되도록 공기의 흐름을 유발시키는 에어팬으로 구성된다.The air purifier is installed to purify polluted air generated in homes, offices, industrial sites, and the like, and includes a purifier body having an air inlet and an air outlet, and filters air introduced through the air inlet into a multi-layered body in the purifier body. And an air fan built in the purifier body to induce the flow of air so that the outside air is introduced into the purifier body and the air filtered by the air filter is discharged into the room through the air outlet.
따라서, 분진이나 각종 세균등으로 인해 오염된 실내공기는, 에어팬의 흡입력에 의해 공기 유입구를 통해 정화기 본체 내로 유입된 후, 다층으로 적재된 에어필터를 통해 여과된 다음 공기 배출구를 통해 실내로 배출된다.Therefore, indoor air contaminated by dust or various bacteria is introduced into the purifier main body through the air inlet by the suction force of the air fan, and then filtered through the air filter stacked in multiple layers and then discharged into the room through the air outlet. do.
그러나, 전술한 구성을 갖는 종래 공기정화기의 경우, 아무리 성능이 우수한에어필터를 사용한다 하더라도 공기정화에는 한계가 있다. 특히, 미세한 유해물질이나 세균의 경우에는 에어필터에서 걸러지지 않고 그대로 외부로 배출될 염려가 있으며, 세균의 경우에는 공기정화기 내에서 번식할 우려도 있다.However, in the case of the conventional air purifier having the above-described configuration, no matter how excellent the air filter is used, there is a limit to the air purification. Particularly, in the case of minute harmful substances or bacteria, there is a risk of being discharged to the outside without being filtered out of the air filter, and in the case of bacteria, there is a fear of breeding in the air purifier.
본 고안은 전술한 바와 같은 종래의 문제점을 해소하기 위하여 안출된 것으로, 자외선램프와 광촉매가 코팅된 필터부재를 구비하여, 자외선램프 작동시 방사되는 자외선이 광촉매에 닿을 때 발생되는 광촉매반응으로 미세한 유해물질까지도 정화하고 세균도 박멸할 수 있는 광촉매식 필터장치를 제공하는데 그 목적이 있다.The present invention has been devised to solve the conventional problems as described above, and provided with a filter member coated with an ultraviolet lamp and a photocatalyst, the photocatalytic reaction generated when the ultraviolet rays that are emitted during the operation of the ultraviolet lamp touches the photocatalyst. It is an object of the present invention to provide a photocatalytic filter device capable of purifying even substances and eradicating bacteria.

이하, 본 고안에 따른 광촉매식 필터장치의 바람직한 실시예를 통하여 전술한 바와 같은 구성의 특징과 그 작용을 보다 상세히 설명하기로 한다.Hereinafter, the features and the operation of the above-described configuration through the preferred embodiment of the photocatalyst filter device according to the present invention will be described in more detail.
도 1 및 도 2에 도시된 바와 같이 본 고안의 일 실시예에 따른 광촉매식 필터장치(40)는, 공조기 또는 공기정화기(1) 내에 설치되는 자외선램프(41), 및 공조기 또는 정화기 내에서 자외선램프(41)와 이격되게 설치되며 그 표면에 광촉매가 코팅된 필터부재(42)를 포함하여 이루어진다.As shown in FIG. 1 and FIG. 2, the photocatalytic filter device 40 according to an embodiment of the present invention includes an ultraviolet lamp 41 installed in an air conditioner or an air purifier 1, and an ultraviolet light in an air conditioner or a purifier. It is installed to be spaced apart from the lamp 41 and comprises a filter member 42 coated with a photocatalyst on the surface.
본 고안에 따른 광촉매식 필터장치(40)는, 도면에 도시한 형태의 공기정화기 뿐만 아니라 다른 형태의 공기정화기에도 사용할 수 있고, 공조기의 경우에도 주방, 거실, 사무실 등에 설치되는 천장형 공조기뿐만 아니라 다른 형태의 공조기에도 사용할 수 있다.The photocatalytic filter device 40 according to the present invention can be used not only for the air purifier of the type shown in the drawings, but also for other types of air purifiers, and in the case of an air conditioner, not only a ceiling type air conditioner installed in a kitchen, a living room, an office, etc. It can also be used for other types of air conditioners.
참고로, 본 실시예의 도면에 도시된 공기정화기(1)는, 도 1에 도시된 바와 같이 공기흡입구(10)가 후방측에 형성되고, 공기의 흐름을 유발하는 에어팬(20)이 공기흡입구(10) 측에 설치되며, 정화된 공기를 토출하기 위한 토출그릴(30)이 전방측에 설치되고, 내측에 본 고안에 따른 광촉매식 필터장치(40)가 설치되는 구조로 이루어진다.For reference, in the air purifier 1 shown in the drawings of this embodiment, as shown in FIG. 1, the air inlet 10 is formed at the rear side, and the air fan 20 for inducing the flow of air is the air inlet. It is provided on the (10) side, the discharge grill 30 for discharging the purified air is provided on the front side, and the photocatalyst filter device 40 according to the present invention is installed on the inside.
전술한 자외선램프(41)는, 도 3에 도시된 바와 같이 투명한 바(Bar)형태의 유리관(411)과, 유리관(411)의 양단에 장착된 베이스(412)와, 베이스(412)의 내측에 장착된 히팅필라멘트(413), 및 히팅필라멘트(413)와 연결되어 공조기 또는 공기정화기(1) 내에 설치된 전원단자와 전기적으로 접속되는 램프핀(414)으로 구성된다.As described above, the ultraviolet lamp 41 has a transparent bar-shaped glass tube 411, a base 412 mounted at both ends of the glass tube 411, and an inner side of the base 412. It is composed of a heating filament 413 mounted on, and a lamp pin 414 connected to the heating filament 413 and electrically connected to a power terminal installed in the air conditioner or the air purifier 1.
이 때, 자외선램프(41)는 그 파장이 254~400㎚일 경우, 바람직하게는 360~400㎚일 때 살균 및 냄새 제거등의 효과가 가장 우수하다.At this time, the ultraviolet ray lamp 41 has the most excellent effect such as sterilization and odor removal when its wavelength is 254-400 nm, preferably when it is 360-400 nm.
이처럼 254~400㎚의 파장을 갖는 자외선이 광촉매와 반응하여 광촉매반응을 일으키게 되면, 산화작용을 해서 이온화 산화분자를 생성하는 것과 이온화 산화분자가 붙어 있는 유기물질을 산화분해하는 반응을 나타내게 된다.When the ultraviolet rays having a wavelength of 254 to 400 nm react with the photocatalyst to cause the photocatalytic reaction, the oxidative reaction generates the ionized oxidized molecule and oxidizes and decomposes the organic material having the ionized oxidized molecule.

이하에서는, 전술한 바와 같이 구성된 본 고안의 일 실시예에 따른 광촉매식 필터장치의 작용을 상세히 설명하기로 한다.Hereinafter, the operation of the photocatalyst filter device according to an embodiment of the present invention configured as described above will be described in detail.
먼저, 공기정화기(1) 내에 설치된 에어팬(20)이 작동하게 되면, 공기정화기(1)의 후방측에 형성된 공기흡입구(10)를 통해 실내의 공기가 흡입되고, 흡입된 공기는 자외선램프(41), 필터부재(42) 및 토출그릴(30)을 통해 실내로 다시 토출된다.First, when the air fan 20 installed in the air purifier 1 is operated, the indoor air is sucked through the air inlet 10 formed at the rear side of the air purifier 1, and the sucked air is an ultraviolet lamp ( 41) is discharged back into the room through the filter member 42 and the discharge grill 30.
이 과정에서, 에어팬(20)이 작동하게 되면 자외선램프(41)가 동시에 작동하여 자외선을 방사하게 되고, 자외선램프(41)에서 방사되는 자외선이 필터부재(42)에 코팅된 광촉매에 닿아 자유 전자-전기홀을 형성하게 된다.In this process, when the air fan 20 is operated, the ultraviolet lamp 41 operates simultaneously to emit ultraviolet rays, and the ultraviolet rays emitted from the ultraviolet lamp 41 come into contact with the photocatalyst coated on the filter member 42 to be free. Electron-electric holes are formed.
이 자유 전자-전기홀은 공기중에 함유된 수분이나 산소와 반응하여 수산화기(OH radical)를 생성하게 되며, 이 수산화기는 각종 유기 및 무기 반응원과 반응하여 오염원의 특성을 안정된 상태로 변화시키게 된다.This free electron-electron hole reacts with moisture or oxygen contained in the air to generate hydroxyl radicals, which react with various organic and inorganic reactants to change the characteristics of the pollutant to a stable state.
특히, 수산화기는 소독이나 살균에 널리 사용되고 있는 염소나 치아염소산, 과산화수소, 오존 등보다 훨씬 강한 산화력을 갖는다.In particular, the hydroxyl group has a much stronger oxidizing power than chlorine, hypochlorite, hydrogen peroxide, ozone and the like widely used for disinfection and sterilization.
따라서, 필터부재(42)를 통과하는 공기가 광촉매로부터 발생되는 자유 전자-전기홀과 접촉하게 되면, 공기중에 함유된 수분이나 산소가 자유 전자-전기홀과 반응하여 수산화기를 생성하게 되고, 이 수산화기로 인해 공기중에 함유된 유해물질이 안정된 상태로 분해되고, 각종 세균이 박멸되며, 악취가 제거된다.Therefore, when the air passing through the filter member 42 comes into contact with the free electron-electron hole generated from the photocatalyst, moisture or oxygen contained in the air reacts with the free electron-electron hole to generate a hydroxyl group. As a result, harmful substances contained in the air are decomposed into a stable state, various bacteria are eliminated, and odors are removed.
