본 발명은 자동차의 환기장치용 에어필터에 대한 것으로, 이 에어필터의 일부분에 인체에 유해한 가스를 차단할 수 있는 활성탄 보유부분을 마련하되, 인체에 유해한 가스가 화학적 반응에 의해 근본적으로 제거되도록 하는데 특징이 있는 것이다.The present invention relates to an air filter for a vehicle ventilation device, provided with a portion of the air filter for holding activated carbon that can block a gas harmful to the human body, it is characterized in that the gas harmful to the human body is essentially removed by a chemical reaction Is there.

일반적으로 차내의 공기는 승차인원의 호흡등에 의해 점차 오염되기 때문에 외부의 신선한 공기를 끌어 들여 차내의 공기와 교환해 줄 필요가 있다.In general, the air in the car is gradually contaminated by breathing of passengers, so it is necessary to bring in fresh air from the outside and exchange it with the air in the car.

이와 같이 외부의 공기를 차량 실내로 흡입하여 공급하는 장치를 환기장치라 하는데 주로 강제순환방식의 환기장치를 사용하며, 외부공기 속에 존재하는 이물질 및 유해성분을 차단하기 위한 에어필터가 반드시 구비되어 있다.As such, a device that inhales and supplies external air into a vehicle interior is called a ventilation device. A ventilation device of a forced circulation method is mainly used, and an air filter must be provided to block foreign substances and harmful components present in the external air. .

이와 같이 사용되는 종래의 에어필터는 도 1에서 보는 바와 같이 1㎛이상의 먼지와 분진을 정전기 방식에 의해 걸러주기 위한 1차 여과층(1)이 있고, 그 다음으로는 1㎛이하의 미세한 냄새 입자와 SOx, NOx, H2S 등의 유해가스를 미세기공 사이에 포집할 수 있도록 한 활성탄재질의 2차 여과층(2)을 필수 구성부분으로 하고 있다.The conventional air filter used as described above has a primary filtration layer 1 for filtering dust and dust of 1 μm or more by an electrostatic method as shown in FIG. 1, followed by fine odor particles of 1 μm or less. The secondary filtration layer 2 made of an activated carbon material capable of collecting harmful gases such as SOx, NOx and H2S between the micropores is an essential component.

그러나 이러한 종래의 에어필터는 활성탄재질의 2차 여과층(2)부분에 있어서 그 기능이 매우 미흡하다.However, such a conventional air filter is very poor in the function of the secondary filter layer (2) of the activated carbon material.

즉, 냄새 입자와, SOx, NOx, H2S, NH3, O3 등의 인체 유해가스들을 활성탄재질이 갖는 다수의 미세기공 속에 포집할 수 있도록 되어 있는데, 사실상 포집효과가 있기는 하지만 장시간 흡착하고 있지는 못하기 때문에 어느정도 시간이 지나면 냄새 및 유해 가스 입자들을 다시 풀어 내 보내는 형편이기 때문에 급소기 유해가스가 유입되는 것을 방지하는 정도에 불과하여 근본적인 해결책이 되지 못하고 있는 실정이다.In other words, it is possible to capture odor particles and human harmful gases such as SOx, NOx, H2S, NH3 and O3 into a number of micropores of activated carbon material, which is effective in collecting but not adsorbed for a long time. Therefore, after some time, the odors and harmful gas particles are released again, and thus the situation is not a fundamental solution because it is only a degree of preventing harmful gas from flowing in.

따라서 본 발명은 상기와 같은 종래의 문제점을 해결 보완하기 위해 안출하는 것으로 발명의 주된 목적은 흡착 활성탄재질의 2차 여과부를 구비하되, 촉매 원소를 코팅시켜 인체에 유해가스들이 미세한 기공들 사이로 포집되었을 때, 유해가스들과 화학반응을 일으켜 유해한 성분이 다시 발산되지 못하도록 근본적으로 해소할 수 있도록 하고자 하는데 있는 것이다.Therefore, the present invention is to devise to solve the above-mentioned conventional problems. The main object of the present invention is to provide a secondary filtration unit of the adsorption activated carbon material, coating the catalytic element has been collected by the harmful gas in the human body pores At this time, it is intended to be able to fundamentally solve the harmful components to be released again by causing a chemical reaction with the harmful gases.

본 발명의 필터 구성은 1차 여과층(1)과 2차 여과층(2)으로 이루어 지며, 1차 여과층(1)은 공기중의 약 1㎛이상의 크기를 갖는 분진과 이물질을 정전기 흡착방식에 의해 걸러 주는 미립자필터(Particulate Filter)로써 종래와 대동소이하고, 2차 여과층(2)은 약 1㎛이하의 크기를 갖는 악취 및 인체유해가스를 걸러내기 위한 것으로 흡착 활성탄(21)을 주성분으로 하되, 인체유해가스에 반응하여 촉매재를 코팅시킨 것이다.The filter configuration of the present invention is composed of a primary filtration layer (1) and a secondary filtration layer (2), the primary filtration layer (1) is an electrostatic adsorption method for dust and foreign matter having a size of about 1 ㎛ or more in the air It is similar to the conventional one as a particulate filter (Particulate Filter) to filter by, and the secondary filtration layer (2) is to filter odor and harmful gases having a size of about 1 μm or less, the main component of the adsorbed activated carbon (21) However, the reaction is to coat the catalyst material in response to human harmful gases.

촉매재는 NOx, SOx, O3, H2S, NH3, NH4, HF, Cl2 등의 인체유해가스를 대상으로 하여 접하였을 때 화학반응하는 KOH, MO, H3PO4 를 주성분으로 하는 것이다.The catalyst material is mainly composed of KOH, MO, H3PO4 which are chemically reacted when contacted with human harmful gases such as NOx, SOx, O3, H2S, NH3, NH4, HF and Cl2.

이러한 촉매재를 흡착 활성탄(21)에 코팅하는 방법으로는 상기 촉매재를 슬러리 상태로 만든 후, 슬러리상태의 촉매재 속에 흡착 활성탄(21)을 디핑(Dipping)코팅하거나 또는 촉매재를 활성탄에 화학증착하여 코팅하는 것이다.In the method of coating the catalyst material on the adsorption activated carbon 21, the catalyst material is made into a slurry state, and then the adsorption activated carbon 21 is dipping in the slurry catalyst material, or the catalyst material is chemically activated on the activated carbon. By vapor deposition.

이와 같은 방법으로 코팅하여 촉매재가 흡착 활성탄(21)의 미세기공 내부 표면에 골고루 코팅되는 것이다.By coating in this way, the catalyst material is evenly coated on the inner surface of the micropores of the adsorption activated carbon 21.

다음은 상기와 같이 구성된 본 발명 필터의 필터링 상태를 설명한다.The following describes the filtering state of the filter of the present invention configured as described above.

자동차의 환기장치에 의해 외부의 공기가 강제 흡입되면, 가장 먼저 필터를 통과하게 되는 바, 외부 공기가 본 발명의 필터를 통과하게 되면, 미립자필터(Particulate Filter)인 1차 여과층(1)에서 공기중의 약 1㎛이상의 크기를 갖는 분진과 이물질을 정전기 흡착방식으로 걸러 낸다.When the outside air is forcibly sucked by the ventilation device of the vehicle, the first pass through the filter, when the outside air passes through the filter of the present invention, in the primary filtration layer 1, which is a particulate filter (Particulate Filter) Dust and foreign substances having a size of about 1 ㎛ or more in the air are filtered out by electrostatic adsorption.

다음으로 2차 여과층(2)에서는 약 1㎛이하의 크기를 갖는 악취 및 인체유해가스를 여과하게 되는데, 유해가스가 흡착 활성탄(21)의 미세기공사이로 유입되면 그 작용은 다음과 같다. 예컨데,Next, in the secondary filtration layer 2, odor and harmful gas having a size of about 1 μm or less are filtered. When harmful gas is introduced into the micropores of the adsorbed activated carbon 21, the action is as follows. For example,

SOx가스가 촉매반응을 하면 SOx + MO(KOH)(촉매) = SM(고체중성염) + O2 또는 H2O가 되고,When SOx gas catalyzes, it becomes SOx + MO (KOH) (catalyst) = SM (solid neutral salt) + O2 or H2O,

NOx가스가 촉매반응을 하면 NOx + MO(KOH)(촉매) = NM(고체중성염) + O2 또는 H2O가 되며,When NOx gas catalyzes, it becomes NOx + MO (KOH) (catalyst) = NM (solid weight salt) + O2 or H2O,

NH3가스는 NH3 + H3PO4(촉매) = (NH4)2HPO4(고체중성염)NH3 gas is NH3 + H3PO4 (catalyst) = (NH4) 2HPO4 (solid neutral salt)

O3가스는 O3 + MO(촉매) = MO + O2가 되는 등,O3 gas becomes O3 + MO (catalyst) = MO + O2,

유해성분들은 대부분 고체염으로 만들어져 남고, 무해한 가스(O2)만 차량 내부로 공급되는 것이다.Most of the harmful components are made of solid salts, and only harmless gas (O2) is supplied into the vehicle.

위에서 상세히 설명한 바와 같은 본 발명은 1차 여과층에서는 종전과 마찬가지로 약 1㎛이상의 크기를 갖는 분진과 이물질을 정전기 흡착방식으로 걸러 내도록 하고, 그 다음 2차 여과층에서 약 1㎛이하의 크기를 갖는 악취 및 인체유해가스를 여과하되, 촉매재의 촉매원소가 인체유해성분이 갖는 분자와 촉매반응을 일으켜 유해성분이 고체화 되도록 하였기 때문에 근본적으로 제거할 수 있게 되는 것이며, 따라서 차량의 실내로 악취 및 인체유해가스가 유입되는 것을 보다 철저히 차단할 수 있게 되는 것이다.As described in detail above, the present invention is to filter out dust and foreign matter having a size of about 1 μm or more in the first filtration layer by electrostatic adsorption method, and then have a size of about 1 μm or less in the secondary filtration layer. The odor and harmful gases are filtered, but the catalyst element of the catalyst material reacts with the molecules of the harmful components to solidify the harmful components, so that the odor and harmful gases can be removed.
