Abstract

본 발명은 내연기관 배기가스로부터 입자, 특히 매연 입자의 제거방법 및 장치에 관한 것이다. 본 발명에 따라 입자가 전극(4)에 의해 정전기적으로 대전된다. 입자 및 입자덩어리는 금속미세필터(5)에 의해 제거된다. 바람직하게는, 미세필터(5)의 재로(5a), 바람직하게는 페라이트 소결 금속자체가 수집전극으로 사용된다. 전극에는 고전압(6)이 인가된다. 때때로, 바람직하게는 주기적으로 미세필터를 통해 전류가 공급되고(11, 12), 상기 전류는 입자의 점화온도 이상으로 미세필터(5)의 재로(5a)를 가열시킨다. 필터표면의 바람직한 형상은 원통형, 원뿔대형 및/또는 원추형이다.
