Description
본 발명은 차량용 촉매 변환기에 관한 것으로서, 보다 상세하게는 촉매물질의 도포부위가 확대됨으로써 배기가스의 정화능력이 향상된 차량용 촉매 변환기의 담체에 관한 것이다.The present invention relates to a catalytic converter for a vehicle, and more particularly, to a carrier for a catalytic converter for a vehicle, in which an area to which a catalytic substance is applied is enlarged to improve the ability to purify an exhaust gas.
일반적으로 차량의 엔진에서 배출되는 배기가스는 고온.고압 상태이고, 일산화탄소나 질소산화물 등의 유해물질을 함유하고 있다. 그러므로, 배기가스가 그대로 외부에 방출될 경우, 급격한 팽창으로 인한 폭발음 때문에 과다한 소음이 발생할 뿐만 아니라, 환경오염에 상당한 악영향을 미치게 된다.Generally, the exhaust gas discharged from the engine of the vehicle is in high temperature and high pressure and contains harmful substances such as carbon monoxide and nitrogen oxides. Therefore, when the exhaust gas is directly discharged to the outside, excessive noise is generated due to the explosion sound due to the rapid expansion, and the environmental pollution is considerably adversely affected.
따라서, 차량에는 이러한 배기가스의 고온.고압 상태를 완화시키는 소음기와, 배기가스에 함유된 유해물질을 무해물질로 바꾸는 촉매 변환기 등으로 이루어진 배기장치가 설치되어 있다. 여기서, 상기 촉매 변환기는 배기관의 중간에 설치되는 바, 도1에 나타난 것과 같이 케이스(10)와, 상기 케이스(10) 내에 설치된 담체로 이루어져 있다. 상기 담체는 촉매의 유효면적을 크게 하기 위한 토대로 사용하는 것으로서, 세라믹으로 된 작은 구슬(pellet)을 금속제 케이스에 넣어 그 사이로 배기가스가 통과하도록 하는 펠릿 타입 담체와 내열, 내부식성의 금속선으로 짜여진 그물망의 판을 감아서 만들고 그 표면에 촉매물질을 도포한 금속제 담체 등으로 구분된다.Therefore, the vehicle is provided with an exhaust device comprising a silencer for relieving the high-temperature and high-pressure state of the exhaust gas, and a catalytic converter for converting harmful substances contained in the exhaust gas into harmless substances. Here, the catalytic converter is installed in the middle of the exhaust pipe. As shown in FIG. 1, the catalytic converter is composed of a case 10 and a carrier provided in the case 10. The carrier is used as a base for increasing the effective area of the catalyst. The carrier is composed of a pellet type carrier in which a small pellet made of ceramic is put into a metal case to allow exhaust gas to pass therethrough, and a mesh- And a metal carrier coated with a catalyst material on its surface.
상기 금속제 담체는 도2에 나타난 것과 같이 금속판(12)과, 상기 금속판(12)의 표면에 형성된 중간층으로 이루어져 있는 바, 중간층은 금속재의 파형부재(14)로 이루어져 있고 상기 파형부재(14)의 표면에 실제 촉매층으로 백금(Pt)과 로디움(Rh) 또는 팔라듐(Pd)과 로디움(Rh)이 촉매물질로서 얇게 도포되어 있다.The metal carrier is composed of a metal plate 12 and an intermediate layer formed on the surface of the metal plate 12 as shown in FIG. 2. The intermediate layer is composed of a corrugated member 14 of a metal material. Platinum (Pt), rhodium (Rh), palladium (Pd), and rhodium (Rh) are thinly coated as a catalyst material on the surface of the catalyst layer.
따라서, 이와 같이 구성된 종래의 촉매 변환기는 케이스(10) 내로 배기가스가 유입되면 상기 촉매 물질이 배기가스에 함유된 일산화탄소(CO), 탄화수소(HC), 질소산화물(NOx) 등의 유해물질을 이산화탄소(CO2), 수증기(H2O), 산소(O2), 질소(N2) 등의 무해물질로 환원시킴으로써 배기가스에 함유된 유해물질을 감소시키는 작용을 한다.Therefore, in the conventional catalytic converter thus configured, when the exhaust gas flows into the case 10, the catalytic material converts the harmful substances such as carbon monoxide (CO), hydrocarbon (HC), and nitrogen oxide (NOx) contained in the exhaust gas into carbon dioxide (CO 2 ), water vapor (H 2 O), oxygen (O 2 ), nitrogen (N 2 ) and the like to reduce the harmful substances contained in the exhaust gas.
그러나, 상술한 바와 같은 종래의 차량용 촉매 변환기의 담체는 촉매물질이 파형부재(14)의 표면에만 도포되어 있기 때문에 상기 파형부재(14)가 금속판(12)으로부터 떨어져 나갈 경우, 배기가스의 정화능력이 급격히 감소된다는 문제점이 발생한다.However, in the conventional carrier for a catalytic converter for a vehicle as described above, when the corrugated member 14 is separated from the metal plate 12 because the catalytic material is applied only to the surface of the corrugated member 14, There is a problem in that the amount of the water is rapidly reduced.
본 발명은 상기와 같은 종래기술의 문제점을 해결하기 위하여 안출된 것으로서, 촉매물질이 금속판에도 도포됨으로써 정화능력이 향상된 차량용 촉매 변환기의 담체를 제공하는 것을 목적으로 한다.It is an object of the present invention to provide a carrier for a catalytic converter for a vehicle having improved purification ability by coating a catalytic material on a metal plate.

상기의 목적을 이루기 위하여 본 발명은 촉매물질이 도포된 파형부재와, 상기 파형부재가 부착된 금속판을 포함하는 차량용 촉매 변환기의 담체에 있어서, 상기 금속판의 표면에는 촉매물질로 이루어진 촉매층이 형성되는 것을 특징으로 하는 차량용 촉매 변환기의 담체를 제공한다.In order to achieve the above object, the present invention provides a carrier for a catalytic converter for a vehicle including a corrugated member coated with a catalytic material and a metal plate having the corrugated member, wherein a catalyst layer made of a catalytic material is formed on the surface of the metallic plate The present invention provides a carrier for a catalytic converter for a vehicle.

이하, 첨부된 도면을 참조하여 본 발명의 실시예를 상세하게 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
본 실시예는 본 발명의 범위를 한정하는 것이 아니고, 단지 예시로 제시된 것이며, 도면에서 종래의 구성과 동일한 부분에는 동일한 부호를 부여하고, 중복되는 설명을 생략한다.The present invention is not limited to the scope of the present invention, but is merely provided as an example.

도3은 본 발명에 의한 차량용 촉매 변환기의 담체의 구성을 나타낸 개략도로서 금속판(12)에는 촉매물질이 도포된 파형부재(14)가 접합되는 바, 상기 촉매물질은 금속판(12)에도 도포됨으로써 금속판(12)의 표면에 촉매층(20)을 이루게 된다.FIG. 3 is a schematic view showing the configuration of a carrier of a catalytic converter for a vehicle according to the present invention, in which a corrugated member 14 coated with a catalyst material is bonded to a metal plate 12, The catalyst layer 20 is formed on the surface of the catalyst layer 12.
상술한 바와 같이 구성된 본 실시예에 의한 차량용 촉매 변환기의 담체의 작용을 설명하면 다음과 같다.The operation of the carrier of the catalytic converter for a vehicle according to the present embodiment configured as described above will now be described.
케이스(10) 내로 배기가스가 유입되면 배기가스에 함유된 각종 유해물질이 우선 중간층을 이루는 파형부재(14)에 접하게 되고, 상기 파형부재(14)에 도포된 촉매물질에 의해 무해물질로 환원되는 바, 배기가스가 중간층을 지나 금속판(12)에 이르러서도 그 표면에 형성된 촉매층(20)의 촉매물질에 의해 무해물질로 환원된다. 또한, 상기 파형부재(14)가 금속판(12)으로부터 떨어져 나간 경우에도 금속판(12)에 형성된 촉매층(20)의 촉매물질이 환원작용을 수행함으로써 배기가스의 정화작용에는 차질이 없게된다.When the exhaust gas flows into the case 10, various harmful substances contained in the exhaust gas first come into contact with the corrugated member 14 forming the intermediate layer, and are reduced to a harmless substance by the catalyst material applied to the corrugated member 14 When the exhaust gas passes through the intermediate layer and reaches the metal plate 12, it is reduced to a harmless substance by the catalytic material of the catalyst layer 20 formed on the surface. In addition, even when the corrugated member 14 is separated from the metal plate 12, the catalytic material of the catalyst layer 20 formed on the metal plate 12 performs the reducing action, so that there is no trouble in the purifying action of the exhaust gas.
상술한 바와 같이 본 발명에 따른 차량용 촉매 변환기의 담체에 의하면 금속판에 부착된 파형부재 뿐만 아니라, 금속판 자체에도 촉매물질이 도포됨으로써 배기가스를 더욱 효과적으로 정화할 수 있다는 이점이 있다.As described above, according to the carrier of the catalytic converter for a vehicle according to the present invention, the catalytic material is applied not only to the corrugated member attached to the metal plate but also to the metal plate itself, thereby excellently purifying the exhaust gas.
