Abstract

본 발명은 백하우스를 이용한 배기가스처리설비에서 배기가스에 함유된 분지을 연속적으로 처리하기 위한 방법을 관한 것으로, 특히 백하우스내 압력강하를 검출하여 백필터에 코팅된 미분탄이나 코크스의 상태를 파악함으로써 연속조업이 가능한 압력강하를 이용한 백하우스에서의 끝끝한 분진연속처리방법에 관한 것이다.The present invention relates to a method for continuously treating a branch contained in an exhaust gas in an exhaust gas treatment facility using a baghouse, and in particular, by detecting a pressure drop in the baghouse and grasping the state of the pulverized coal or coke coated on the bag filter The present invention relates to a method for continuous treatment of dust at the end of a baghouse using a pressure drop capable of continuous operation.

본 방법은 백 필터의 미분탄 도포상태를 백하우스내 압력강하를 검출하여 파악함으로써 연속적인 조업이 가능하다. 따라서, 모든 분진제거 응용분야에서 분진의 연속적인 처리를 행할 수 있게 되어, 소규모 플랜트는 물론 대규모 플랜트 및 기타분야에서도 적용이 용이한 잇점을 갖는다.In this method, continuous operation is possible by detecting the pulverized coal application state of the bag filter by detecting the pressure drop in the baghouse. Therefore, it is possible to perform continuous treatment of dust in all dust removal applications, which is advantageous in application to large-scale plants and other fields as well as small-scale plants.
