Abstract

본 발명은, 배기가스에 포함되어 있는 유독가스를 제거하기 위하여 촉매체가 내장되는 촉매컨버터의 형성에 있어서의 촉매컨버터의 배기가스유비부에 확산 유도파이프를 형성하여, 배기가스가 촉매체의 모노리드의 중앙으로 집중화되는 것을 분산시키어 촉매의 정화효율을 높일 수 있는 배기가스의 촉매컨버터 통과 변화 장치에 관한 것으로, 배기가스가 배기되는 배기관과 연결되어 통하도록 된 컨버터내부에 정화 기능을 발휘하는 촉매체 및 모노리드를 형성하여, 컨버터에서 배출되는 배기 유독 가스를 정화시킴에 있어서, 상기의 컨버터(10)의 배기유입구(11)의 넥크부에, 배기가스를 분할 확산시킬 수 있는 확산유도파이프(40)를 형성하여, 배기유입구(11)쪽으로부터 유입되는 배기가스의 중앙집중화를 유도 분산시키어, 컨버터(10)내를 통과할 수 있도록 한 것이며, 상기 확산유도파이프(40)는, 다수의 파이프(41)가 단일체로 형성되어 중앙쪽은 작은 직경이고, 그의 둘레면은 큰 직경의 칫수로 이루어져 있고, 그의 출구부쪽이 중앙으로부터 원주방향으로 경사진 출구부를 가지는 파이프(41)로 이루어져, 그의 출구부의 배기가스가 컨버터의 모노리드(30)의 전면적을 균일하게 확산 분포되도록 한 것이다.According to the present invention, a diffusion induction pipe is formed in the exhaust gas ubiquitous portion of the catalytic converter in the formation of a catalytic converter in which a catalyst body is incorporated in order to remove toxic gas contained in the exhaust gas. The present invention relates to a catalytic converter passage change device for exhaust gas that can disperse centralized gas and improve the catalyst purification efficiency. The catalyst body exhibits a purification function inside a converter connected to an exhaust pipe through which exhaust gas is exhausted. And a diffusion induction pipe 40 capable of dividing and diffusing the exhaust gas into the neck portion of the exhaust inlet 11 of the converter 10 in forming a monolith to purify the exhaust toxic gas discharged from the converter. ) To induce and disperse the centralization of the exhaust gas flowing from the exhaust inlet 11 and pass through the converter 10. The diffusion induction pipe 40 has a plurality of pipes 41 formed in a single body, the center of which is a small diameter, the circumferential surface of the large diameter dimension, its outlet portion is circumferential from the center It consists of the pipe 41 which has the exit part inclined in the direction, and the exhaust gas of the exit part is spread | diffused uniformly over the whole area of the monolith 30 of a converter.
