Description
본 고안은 원뿔형 촉매형상을 지닌 삼원 촉매 전환 장치에 관한 것으로, 더욱 상세하게는, 자동차의 대기가스 정화 장치인 삼원 촉매 전환 장치내부의 촉매의 형상을 변경하여 정화 효율을 극대화 시킨 원뿔형 촉매형상을 지닌 삼원 촉매 전환 장치에 관한 것이다.The present invention relates to a three-way catalytic conversion device having a conical catalyst shape, and more particularly, to a conical catalyst shape that maximizes the purification efficiency by changing the shape of the catalyst in the three-way catalytic conversion device, which is an atmospheric gas purification device for automobiles. A three-way catalytic converter.
일반적으로, 자동차에서 배출되는 배기가스는 일산화탄소, 탄화수소, 질소화합물 등이 포함되어 있어 대기 오염의 원인이 된다. 대기로 방출되는 상기 일산화탄소, 탄화수소, 질소화합물 등을 감소하기 위하여 실린더에서 배출된 배기가스를 정화하는 장치로서 삼원 촉매 전환 장치가 장착된다.In general, exhaust gases emitted from automobiles contain carbon monoxide, hydrocarbons, nitrogen compounds, etc., which cause air pollution. In order to reduce the carbon monoxide, hydrocarbons, nitrogen compounds and the like emitted to the atmosphere, a three-way catalytic conversion device is installed as a device for purifying exhaust gas discharged from a cylinder.
삼원 촉매 전환 장치는 배기 통로에 마련된 촉매의 작용에 의해 배기가스를 정화하는 것으로 백금 등의 산화 촉매를 사용하여 일산화 탄소와 탄화 수소를 이산화탄소 및 물로 변환 시킨다.The three-way catalytic conversion device purifies the exhaust gas by the action of a catalyst provided in the exhaust passage, and converts carbon monoxide and hydrocarbon into carbon dioxide and water using an oxidation catalyst such as platinum.
즉, 삼원 촉매 장치라 함은 배기가스 중 유독한 성분 CO, HC, NOX를 가리키며 이들 3개의 성분을 동시에 감소시키는 장치이다. 삼원 촉매 전환 장치는 배기관 도중에 설치되어, 상술된 백금 뿐만 아니라 로듐이 사용된다. 유해한 일산화 탄소와 탄화수소를 산화하여 각각 무해한 이산화탄소와 물로 변화시키는데에는 충부한 산소가 필요하지만 산화질소를 무해한 질소로 변화시키는데 산소는 방해된다.That is, the three-way catalyst device refers to the toxic components CO, HC, and NOX in the exhaust gas and simultaneously reduces these three components. The three-way catalytic converter is installed in the middle of the exhaust pipe, so that not only platinum but also rhodium is used. Sufficient oxygen is required to oxidize harmful carbon monoxide and hydrocarbons into harmless carbon dioxide and water, respectively, but oxygen is hindered to convert nitrogen oxide into harmless nitrogen.
따라서, 3개의 성분을 동시에 감소시키는 데에는 혼합기를 산소에 과부족이 없는 이론 공연비에 가까운 곳에서 조정할 필요가 있다.Therefore, to reduce the three components simultaneously, it is necessary to adjust the mixer near the theoretical air-fuel ratio without excess oxygen.
한편, 상기와 같은 삼원 촉매 전환 장치의 내부에는 상술된 촉매가 제공되어 있는바, 그 형상은 보통 원통형이다. 즉, 실린더로부터 배출된 가스는 원통형으로 형성된 다수개의 촉매를 통과하며 정화되는 것이다.On the other hand, the above-described catalyst is provided in the three-way catalytic conversion device as described above, the shape is usually cylindrical. That is, the gas discharged from the cylinder is purified by passing through a plurality of catalysts formed in a cylindrical shape.
그런데, 최근 강화되는 환경관련 법규의 제정으로 상기 삼원 촉매 장치의 성능은 가일층 증대되어야 하였으며 보다 정화 능력이 우수한 삼원 촉매 장치의 개발에 관련된 연구가 활발히 진행되고 있음은 주지와 같다.However, the enactment of environmental regulations that have recently been strengthened, the performance of the three-way catalyst device should be further increased, and it is well known that research related to the development of a three-way catalyst device with better purification ability is actively underway.
따라서, 본 기술분야의 당업자들은 삼원 촉매 전환 장치의 정화 능력을 증대시키는데 고심하여 왔다.Therefore, those skilled in the art have been struggling to increase the purification capability of three-way catalytic conversion devices.
따라서, 본 고안은 상기된 문제점 및 고심사항을 해결하기 위하여 안출된 것으로, 배출가스가 삼원촉매장치 내부에서 좀더 오래 머무를 수 있게 하여 정화 효과를 더욱 증대시키는데 그 목적이 있다.Therefore, the present invention has been devised to solve the above problems and problems, and its purpose is to further increase the purification effect by allowing the exhaust gas to stay longer in the three-way catalyst device.

이하, 본 고안의 바람직한 일 실시예를 첨부도면을 참조로하여 보다 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the present invention will be described in more detail.
도 1은 본 고안에 따른 원뿔형 촉매형상을 지닌 삼원 촉매 전환 장치의 사시도 및 부분 절개 사시도이고, 도 2는 본 고안의 일 실시예에 따른 원뿔형 촉매의 사시도 이다.1 is a perspective view and a partial cutaway perspective view of a three-way catalytic conversion device having a conical catalyst shape according to the present invention, Figure 2 is a perspective view of a conical catalyst according to an embodiment of the present invention.
자동차의 실린더로부터 배출되는 배기가스는 배기가스 파이프를 통과하여 삼원촉매 장치의 내부로 유입된다. 상기 배기가스를 여과시키기 위하여 하우징의 내부에는 상기 배기가스가 통과되는 구멍을 지닌 원뿔형 및 원통형의 촉매(11, 12, 13)가 구비되어 있다. 즉, 상기 삼원 촉매전환 장치(10)의 하우징(15) 내부에는 원뿔형의 제 1 촉매(11)와 제 3 촉매(13)가 상호 마주보는 위치에 형성되어 있고, 그 사이에 제 2 촉매(12)가 위치하고 있다.Exhaust gas emitted from the cylinder of the vehicle passes through the exhaust gas pipe and flows into the three-way catalyst device. In order to filter the exhaust gas, conical and cylindrical catalysts 11, 12 and 13 having a hole through which the exhaust gas passes are provided. That is, the conical first catalyst 11 and the third catalyst 13 are formed at positions facing each other in the housing 15 of the three-way catalytic conversion device 10, and the second catalyst 12 therebetween. ) Is located.
상기 제 1 및 제 3 촉매(11, 13)의 형상은 거의 원뿔형이지만 보다 상세히 설명하면 원통형의 일측에 원뿔이 부착된 형태이다. 상기 촉매(11, 12, 13)에는 가로방향으로 관통되는 구멍(14)이 형성되어 있고 그 구멍(14)을 배기가스가 통과함은 물론이다.The first and third catalysts 11 and 13 have a substantially conical shape, but in more detail, a cone is attached to one side of a cylindrical shape. The catalysts 11, 12, 13 are formed with holes 14 penetrating in the horizontal direction, and the exhaust gas passes through the holes 14.
상기 제 2 촉매(12)는 일측에 상기 제 1 촉매(11)의 원뿔부분이 삽입되는 제 1 요홈이 형성되고 타측에는 상기 제 1 요홈과 같은 크기의 제 2 요홈이 형성되며 전체적인 형상은 원통형이다.The second catalyst 12 has a first groove in which a conical portion of the first catalyst 11 is inserted on one side thereof, and a second groove of the same size as the first groove is formed on the other side thereof, and the overall shape is cylindrical. .
따라서, 상기와 같이 구성된 촉매(11, 12, 13)를 통과하게 되는 배기가스는 각각의 촉매사이에서 부분적으로 와류현상이 발생되고 이에 따라 배기가스가 상기 삼원촉매장치(10)의 내부에서 머므르는 시간도 증대 되었다. 배기가스가 상기와 같이 삼원 촉매 장치에 머므르게 되는 시간이 증대됨에 따라 정화효율도 극대화 됨은 물론이다.Therefore, the exhaust gas passing through the catalysts 11, 12, and 13 configured as described above is partially vortexed between the respective catalysts, so that the exhaust gas stays inside the three-way catalyst device 10. Time has also increased. As the time for the exhaust gas to stay in the three-way catalyst device is increased as described above, the purification efficiency is also maximized.
상기와 같이 구성된 본 고안을 자동차에 설치하는 경우에 배출가스와 촉매간의 접촉시간이 증대되어 결과적으로 정화효율이 극대화 되는 효과가 있다.When the present invention configured as described above is installed in a vehicle, the contact time between the exhaust gas and the catalyst is increased, and as a result, the purification efficiency is maximized.
