Abstract

배기가스정화용 필터는, 내열금속으로 만든 발포구조다공체의 가공내에 섬유의 평균직경이 5~40㎛인 금속섬유 혹은 섬유의 평균직경이 1~40㎛인 내열성세라믹섬유를 분산상태에서 충전, 고정화하여 그 결과, 충전밀도가 5~20%가 되는 금속다공체로 이루어져 있다. 필터는, 금속이나 세라믹섬율 혹은 금속이나 세라믹섬유없이 충전된 상기 발포구조다공체와, 평균직경이 5~40㎛인 금속섬유 혹은 평균직경이 1~40㎛인 내열성 세라믹섬유를 분산상태에서 충전밀도가 5~25%가 되도록 고정화하여 얻은 섬유구조다공체를 적층한 적층구조일 것이다. 디젤엔진의 배기가스중에 포함된 PM(흑연, 미립자 및 SOF)을 포집하는 본 발명한 필터를 사용하면 포집효율은 높게 유지되는 반면, 배기가스,의 압력손실은 최소화가 된다.
