Abstract

공기중에 부유하는 먼지등의 미립자, 연소기관으로 부터 발생하는 매연등의 미립자 및 배기중에 포함되는 질소 산화물(NOx)등의 대기오염 물질의 양을 저하시킬 수가 있는 오염공기용 정화장치, 먼지나 매연등의 미립자는 대전용메시부에서 부로 대전시키고, 그것을 정화용 필터부에서 쿨롬력에 의하여 집진한다. 또 NOx는 탄소섬유 탄소입자의 작용에 의하여 N2및 CO2로 변화되어 농도가 저하된다. 탄소섬유 또는 탄소입자로서는 표면적이 커다란 (200~2,000m2/g)의 변성 탄소섬유 또는 탄소입자를 사용하는 것이 바람직하다.
