FIG. 1 is a schematic view showing a configuration of an atmospheric purification apparatus according to an exemplary embodiment of the present invention, and FIG. 2 is an atmospheric purification according to the present invention. A partially enlarged view showing part of the device.
도 1 도시와 같이, 자동차의 엔진실(2)에 설치된 내연기관(4)에는 열교환기로서 방열기(radiator;6)가 설치되며, 내연기관(4)과 방열기(6)사이에는 냉각수가 순환되어 내연기관(4)의 작동시 발생되는 열을 외부로 방출시킨다.As shown in FIG. 1, a radiator 6 is installed as an heat exchanger in an internal combustion engine 4 installed in an engine compartment 2 of a vehicle, and cooling water is circulated between the internal combustion engine 4 and the radiator 6. Heat generated during operation of the internal combustion engine 4 is released to the outside.
도 2에 도시한 바와 같이 방열기(6)에는 다수의 냉각핀(8)이 형성되어 표면적을 극대화시킴으로서 냉각파이프(10)를 통과하는 냉각수에 내재된 에너지를 더욱 빨리 외부로 방출시킨다.As shown in FIG. 2, a plurality of cooling fins 8 are formed in the radiator 6 to maximize the surface area, thereby releasing energy inherent in the cooling water passing through the cooling pipe 10 to the outside more quickly.
또한 방열기(6)에는 냉각팬(12)이 설치되어 차량의 운전조건이나 운행속도에 따라 저속 또는 고속으로 회전되면서 방열기(6)를 향해 대기를 강제로 송풍시킨다.In addition, the radiator 6 is provided with a cooling fan 12 to forcibly blow the atmosphere toward the radiator 6 while being rotated at a low speed or a high speed according to the driving conditions or the driving speed of the vehicle.
그리고 자동차의 전방에는 그릴(grille;14)이 형성되어 자동차의 주행시 대기가 그릴(14)로 유입되어 방열기(6)를 관통한다. 특히, 자동차는 빠른 속도로 주행하기 때문에 많은 양의 대기를 정화할 수 있다.In addition, a grill 14 is formed at the front of the vehicle so that the atmosphere flows into the grill 14 when the vehicle runs, and penetrates the radiator 6. In particular, automobiles travel at high speeds and can purify large amounts of air.
이와 같이 구성된 일반적인 자동차에 본 발명의 특징에 따른 대기정화장치가 적용 실시된다.The air purifying apparatus according to the features of the present invention is applied to a general automobile configured as described above.
즉, 방열기(6)에 광촉매재를 코팅시키는 바, 바람직하게는 도 2에 도시한 바와 같이 광촉매재가 담지된 광촉매층(16)을 냉각핀(8)의 표면에 코팅 형성시킨다.광촉매재로는 여러가지가 사용될 수 있으나, 본 발명의 실시예에서는 이산화티타니움(TiO₂)을 사용한다. 광촉매재는 특성 파장의 빛에 의해 여기(勵起)가 되는데, 이러한 과정은 TiO₂→ TiO2(h+) + e- 과 같은 반응식으로 표현된다.That is, the photocatalyst is coated on the radiator 6. Preferably, the photocatalyst layer 16 on which the photocatalyst is loaded is coated on the surface of the cooling fin 8. As shown in FIG. Various things can be used, but the embodiment of the present invention uses titanium dioxide (TiO₂). The photocatalyst is excited by light of a specific wavelength, and this process is expressed by a reaction equation such as TiO 2 → TiO 2 (h +) + e −.
TiO2(h+) + e-는 반응성이 매우 강한 이온체로서 H2O나 O2를 여기시켜 프리 라디칼 생성을 가속, 증배시킨다(당업자에게이미 공지된 기술임. 광촉매에 관한 문헌: J. of Adv Oxid. Technol Vol., No.1, 1996.p67~78p). 이러한 광촉매재는 감마알루미나와 같은 담체에 담지되어 광촉매층을 형성한다.TiO 2 (h +) + e- is a highly reactive ionic material that excites H 2 O or O 2 to accelerate and multiply the free radical generation (a technique already known to those skilled in the art.) Adv Oxid.Technol Vol., No. 1, 1996. p67-78p). This photocatalyst is supported on a carrier such as gamma alumina to form a photocatalyst layer.
그리고 상술한 광촉매재를 여기시키는 광원으로는 자동차의 그릴(14)을 통해 엔진실(2)로 입사되는 태양광을 사용하거나 또는 방열기(6)의 인접한 위치에 자외선을 조사하는 자외선램프(18)를 설치시킨다. 자외선램프(18)에서 조사되는 자외선의 파장은 대략 360nm 영역이다.In addition, as a light source for exciting the photocatalyst described above, an ultraviolet lamp 18 using sunlight incident to the engine compartment 2 through the grill 14 of the vehicle or irradiating ultraviolet rays to an adjacent position of the radiator 6 is used. Install it. The wavelength of the ultraviolet light emitted from the ultraviolet lamp 18 is approximately 360 nm.
자외선램프(18)에는 반사경(20)이 설치되는 바, 본 발명의 특징에 따라 반사경(20)의 내측이 라이에이터(6)를 향하게 설치되어 자동차의 주행시 그릴(14)을 통해 유입되는 대기의 유속으로 인한 압력으로부터 자외선램프(18)를 보호하고, 자외선램프(18)에서 조사된 자외선을 반사시켜 방열기(6)로의 자외선 입사량을 증대시킨다.The ultraviolet light lamp 18 is provided with a reflector 20, and according to the characteristics of the present invention, the inner side of the reflector 20 is installed toward the writer 6 so that the air flowing through the grill 14 during the driving of the vehicle The ultraviolet lamp 18 is protected from the pressure due to the flow rate, and the ultraviolet light emitted from the ultraviolet lamp 18 is reflected to increase the amount of ultraviolet light incident on the radiator 6.
이와 같은 대기정화장치는 자동차의 주행시 다음과 같은 작용을 나타낸다. 자동차의 주행중에는 대기가 항상 그릴(14)을 통해 방열기(6) 쪽으로 흐르게 된다. 이렇게 대기가 방열기(6)를 통과할 때 자외선램프(18)에서 조사된 자외선에 의해 광촉매층(16)의 광촉매재가 여기되면서 프리 라디칼이 형성되고, 이 프리 라디칼이 대기 중에 함유된 부유휘발물질(VOC; Volatile Organic Components), 질소산화물 같은 오염물질을 정화시킨다.Such an air purifying device exhibits the following actions when driving a car. During driving of the vehicle, the atmosphere always flows through the grille 14 toward the radiator 6. As the atmosphere passes through the radiator 6, the photocatalyst of the photocatalytic layer 16 is excited by ultraviolet rays irradiated from the ultraviolet lamp 18, and free radicals are formed, and the free radicals are suspended volatiles contained in the atmosphere ( VOCs (Volatile Organic Components) and pollutants such as nitrogen oxides are cleaned.
여기서, 자동차의 주행속도에 따라서 냉각팬(12)의 회전속도도 변화되며, 방열기(6)에는 계속해서 대기가 송풍되어짐에 따라 주행중에서 대기의 정화가 지속적으로 이루어진다.Here, the rotational speed of the cooling fan 12 is also changed according to the running speed of the vehicle, and the air is continuously blown to the radiator 6 so that the purification of the air is continuously performed while driving.
또한, 다른 실시예로서 자동차의 에어컨에 대기정화장치를 제안한다. 즉, 도 3에 도시한 바와 같이 자동차에 장착된 에어컨(30)은 압축기(32), 응축기(34), 팽창밸브(36) 및 증발기(38)로 구성되어 내부를 순환하는 냉매의 상태변화로 실내를 냉각시키는 공지된 장치이다.In addition, another embodiment proposes an air purifying apparatus for an air conditioner of a vehicle. That is, as shown in FIG. 3, the air conditioner 30 installed in the vehicle is composed of a compressor 32, a condenser 34, an expansion valve 36, and an evaporator 38 to change the state of the refrigerant circulating inside. It is a known device to cool the room.
여기서, 자동차의 에어컨(30)의 일부인 응축기(34)에는 다수의 냉각핀이 설치되어 열교환이 용이하도록 하고 다수의 냉각핀에 광촉매재를 함유한 광촉매층을코팅하며, 응축기(34)의 인접한 위치에 전술한 광원(40)을 설치한다. 이의 작동은 앞서 기술한 실시예와 동일함으로 생략한다.Here, a plurality of cooling fins are installed in the condenser 34, which is part of the air conditioner 30 of the vehicle, to facilitate heat exchange, and to coat the photocatalyst layer containing the photocatalyst on the plurality of cooling fins, and the adjacent position of the condenser 34. The above-described light source 40 is provided. Its operation is omitted because it is the same as the above-described embodiment.
한편, 에어컨 증발기(38)의 인접한 위치에는 냉각팬(42)이 설치되어 자동차의 실내로 열교환된 차가운 공기를 유입시킨다. 여기서 실내로 유입되는 차가운 공기는 자동차 실내에서 계속 순환되거나 또는 외부에서 유입되는데, 실내로 유입되는 공기유입구에는 통상 필터(44)가 설치되어 공기에 포함된 이물질을 제거한다.Meanwhile, a cooling fan 42 is installed at an adjacent position of the air conditioner evaporator 38 to introduce cool air that is heat-exchanged into the interior of the vehicle. Here, the cool air flowing into the room continues to circulate in the vehicle interior or flows in from the outside. An air inlet flowing into the room is usually provided with a filter 44 to remove foreign substances contained in the air.
전술한 대기정화장치의 광촉매층을 금속이나 무기재료 같은 무기물 필터(44)에 코팅 형성시키고, 필터(44)의 인접한 위치에 광원(40)인 자외선램프를 설치시켜 자외선램프에서 조사된 자외선이 광촉매층의 광촉매를 여기시키도록 하면 프리 라디칼이 생성되어 자동차의 실내로 유입되는 공기를 정화시키게 된다.The photocatalyst layer of the above-described atmospheric purification apparatus is coated on an inorganic filter 44 such as a metal or an inorganic material, and an ultraviolet lamp, which is a light source 40, is installed at an adjacent position of the filter 44 so that the ultraviolet light irradiated from the ultraviolet lamp is photocatalyst. Exciting the layer's photocatalyst produces free radicals to purify the air entering the interior of the vehicle.
앞서 기술한 장치들은 자동차 또는 자동차의 에어컨에 국한되지 않고 본 발명의 요지에 벗어나지 않는 범위 내에서 용도이용의 적용이 가능함을 밝히는 바이다. 예를 들면 건물의 공기정화장치등에도 이용 가능하다.The above-described devices are not limited to a car or an air conditioner of a car, and it is revealed that the application can be used within the scope of the present invention. For example, it can be used for an air purifier of a building.
이상에서 살펴본 바와 같이 본 발명에 따른 대기정화장치들은 종래의 문제점을 실질적으로 해소하고 있다.As described above, the atmospheric purification apparatuses according to the present invention substantially solve the conventional problems.
즉, 자동차의 방열기 자동차 에어컨의 응축기 또는 송풍측 필터 부분에 광촉매재를 담지한 광촉매층이 코팅되고 자외선램프에서 조사된 자외선으로 광촉매재를 여기시켜 자동차의 주행시 방열기를 관통하는 대기에 포함된 오염물질을 정화시킨다.That is, a photocatalyst layer carrying a photocatalytic material is coated on a condenser or a blower side filter part of an automobile air conditioner and excites the photocatalyst with ultraviolet rays irradiated from an ultraviolet lamp, so that the pollutants contained in the atmosphere penetrating the radiator during driving of the vehicle. Purify.
이에 따라, 정치식으로 한 자리에 고정된 채 임의의 용량에 맞도록 설계되어 있던 종래의 정화장치에 비해 자동차의 주행이 늘면 늘수록 대기를 정화시키는 효과가 나타나기 때문에 정화용량에 구애되지 않는다.Accordingly, it is not limited to the purification capacity because the effect of purifying the air increases as the driving of the vehicle increases, as compared with the conventional purification device designed to fit an arbitrary capacity while being fixed in one place.
또한, 대기정화를 위한 추가적인 정치식 정화장치가 설치되지 않고 대기정화장치가 자동차에 설치됨으로서 정치식에 비해 시설비가 상대적으로 낮다.In addition, since the stationary purification device is not installed for the air purification and the air purification device is installed in the vehicle, the facility cost is relatively lower than that of the stationary food.
아울러, 정치식 정화장치는 동작을 위한 별도의 운전비용이 소요되지만 본 발명의 대기정화장치는 자동차의 주행이 대기를 정화시키는 효과로 이어지기 때문에 별도의 운전비용이 소요되지 않아도 된다.In addition, the stationary purifier takes a separate driving cost for the operation, but the atmospheric purifying apparatus of the present invention does not require a separate driving cost because the driving of the car leads to the effect of purifying the atmosphere.
