본 발명은 온도센서가 구비되는 자체발열촉매를 컨버터의 내측에 다단 설치하는 구성으로 이루어지며, 상기 자체발열촉매는 전원의 공급에 의해 발열하는 발열체의 외측에 촉매체가 코팅되는 다공성 망상구조체로 이루어져 빠른 촉매 활성화 온도 도달이 가능토록 하는 자체발열촉매를 갖는 정화장치 및 자체발열촉매 제조방법에 관한 것이다.A self-heating catalyst having a temperature sensor is installed at a plurality of stages inside a converter. The self-heating catalyst is composed of a porous network coated with a catalyst on the outside of a heating element that generates heat by the supply of power, The present invention relates to a purification apparatus having a self-extinguishing catalyst capable of achieving a catalyst activation temperature and a self-extinguishing catalyst production method.

일반적으로 자동차 배기가스등은 엔진에서 혼합기 연소에 의해 생성되어 배기 파이프를 통해 대기 중으로 방출되는 가스를 말하며, 이러한 배기가스에는 일산화탄소(CO), 질소산화물(NOx), 미연소탄화수소(HC) 등 인체에 유해한 물질이 다량 포함되어 있다.Generally, automobile exhaust gas is a gas generated by a mixture combustion in an engine and discharged to the atmosphere through an exhaust pipe. This exhaust gas contains carbon monoxide (CO), nitrogen oxides (NOx), unburned hydrocarbons Contains a large amount of harmful substances.

따라서, 자동차 배기가스로 인한 대기오염을 방지하는 것이 환경위생상 중요한 문제로 대두되고 있으며, 자동차에서는 배기가스를 배출하기 전에 반드시 정화처리를 하도록 규제하고 있다.Accordingly, prevention of air pollution caused by automobile exhaust gas is becoming an important issue in environmental hygiene, and automobiles are required to perform purification treatment before discharging exhaust gas.

자동차에서 배기가스를 정화하기 위하여 주로 쓰이는 장치가 삼원촉매(three way catalyst)를 사용한 촉매컨버터인데, 이는 배기 파이프 도중에 장착되며, 차량에 따라 배기가스 배출량이 다르기 때문에 촉매의 사양은 다르다.A catalyst used mainly for purifying exhaust gas in automobiles is a three-way catalytic converter, which is installed in the middle of an exhaust pipe. Since the emission amount of exhaust gas varies depending on the vehicle, specifications of the catalyst are different.

여기서, 삼원촉매는 배기가스의 유해성분인 일산화탄소, 질소산화물 및 탄화수소계 화합물과 동시에 반응하여 이들 화합물을 제거하는 촉매를 의미하며, 주로 Pt/Rh, Pd/Rh 또는 Pt/Pd/Rh계의 삼원촉매가 이용된다.Here, the three-way catalyst means a catalyst which reacts with carbon monoxide, nitrogen oxides and hydrocarbon compounds which are harmful components of the exhaust gas to remove these compounds, and is mainly composed of Pt / Rh, Pd / Rh or Pt / Pd / Catalyst is used.

그리고, 상기한 가솔린 차량 배기가스 정화시스템의 최대 목표는 초기시동시 유해성분의 배출을 최소화 하는데 있으며, 초기 시동시에는 배기가스가 촉매를 통과하지만 촉매가 충분히 워엄-업(warm-up) 되지 않은 상태이고, 촉매의 온도가 배기가스의 유해성분을 무해하게 변환할 수 있을 만큼 충분히 높지 않은 상태이기 때문에, 초기시동시 유해성분의 배출을 최소화 하기 위해서는 촉매의 온도를 최대한 빨리 올려주는 것이 관건이다.The main goal of the gasoline vehicle exhaust gas purification system described above is to minimize the emission of harmful components at the initial start-up, and at the initial start-up, the exhaust gas passes through the catalyst but the catalyst is not sufficiently warm- State and the temperature of the catalyst is not high enough to harmlessly convert the harmful components of the exhaust gas, it is important to raise the temperature of the catalyst as soon as possible in order to minimize the emission of harmful components at the initial start-up.

특히, 전체적으로 HC 및 NOx의 2/3 이상이 초기시동시인 촉매가 충분히 워엄-업 되지 않은 상태에서 배출되므로, 초기시동시 HC 및 NOx의 저감기술이 배기가스 저감기술의 최우선이 되고 있다.Particularly, since more than two-thirds of HC and NOx as a whole are discharged in a state in which the catalyst is not sufficiently warmed up at the time of initial startup, the technology of reducing HC and NOx at the time of initial startup has become a top priority of the exhaust gas reduction technology.

이를 위하여, 촉매컨버터를 엔진의 배기 매니폴드에 최대한 가깝게 설치하거나(CCC:Close Coupled Catalytic Converter), 전기적으로 혹은 연소에 의해 촉매를 가열하여 강제적으로 워엄-업시키는 방법이 제안된 바 있다.For this purpose, a method has been proposed in which the catalytic converter is installed as close as possible to the exhaust manifold of the engine (CCC: Close Coupled Catalytic Converter), or the catalytic converter is warmed up electrically or by burning forcibly.

이와같은 기술과 관련되어 종래의 특허 제610423호에 자동차의 배기가스 정화용 CCC 시스템의 기술이 제시되고 있으며 그 구성은 도1에서와 같이 CCC시스템(100)이, 메인 컨버터(110)와, 이 메인 컨버터(110) 전방에 설치되되 캔(102) 내부에 촉매물질이 코팅된 다수개의 금속 와이어 망(103)을 전후 배치하여 장착 구성한 프리컨버터(101)를 포함하여 이루어진다.In connection with such a technique, a conventional CCC system for automobile exhaust gas purification is disclosed in Patent No. 610423, and a CCC system 100 includes a main converter 110, And a pre-converter 101 disposed in front of the converter 110, in which a plurality of metal wire meshes 103 coated with a catalyst material are disposed in front of and behind the can 102.

그리고, 상기 프리컨버터(101)는 금속 캔(102) 내부에 3 ~ 8개의 금속 와이어 망(103)을 배기가스가 통과할 수 있도록 횡방향의 1~7mm 간격으로 장착하되, 각 와이어 망(103)은 와이어가 이웃한 와이어 망의 와이어와 각각 엇갈리도록 배치하여 제작되는 구성으로 이루어 진다.The pre-converter 101 is installed in the metal can 102 at intervals of 1 to 7 mm in the lateral direction so as to allow exhaust gas to pass through the metal wire nets 103, Are formed by arranging the wires so as to be offset from the wires of the neighboring wire net.

그러나, 상기와 같은 CCC 시스템은, 초기 시동시 정화를 위하여 별도의 프리컨버터(101)를 설치하여야 하여 원가가 상승되는 단점이 있는 것이다.However, the CCC system as described above has a disadvantage in that a separate pre-converter 101 must be installed for purification at the time of initial startup, thereby increasing the cost.

그리고, 상기 프리컨버터(101) 역시 활성화 온도를 필요로 하여 초기 시동시에는 오염물을 완벽하게 제거하기 힘들게 되는 단점이 있는 것이다. Also, since the pre-converter 101 requires an activation temperature, it is difficult to completely remove contaminants at the time of initial startup.

상기와 같은 종래의 문제점들을 개선하기 위하여, 빠른 촉매 활성화 온도 도달이 가능토록 하고, 초기 시동시에도 촉매를 신속하게 활성화시켜 오염물을 제거가 가능토록 하며, 초기 시동시에만 전원을 공급토록 하여 전원의 효율적인 활용이 가능토록 하고, 전체적인 정화성능이 향상되도록 하는 자체발열촉매를 갖는 정화장치 및 자체발열촉매 제조방법을 제공하는데 있다.In order to solve the above conventional problems, it is required to enable rapid catalyst activation temperature to be reached, to rapidly activate the catalyst even at the initial start-up, to remove contaminants, and to supply power only at the initial start- The present invention provides a purification apparatus having a self-extinguishing catalyst and a method of manufacturing a self-extinguishing catalyst, which enables efficient utilization of the exhaust gas and improves the overall purification performance.
