The incoming airflow is deflected by the tangential inlet and cylinder walls into a cyclone pattern, causing a rapid change in direction that separates particles from the air stream by centrifugal force and impact on the walls 离心分离与气流速度表示 Showing centrifugal separation and airstream velocity 沙克龙除尘器的运行与横截面积 Cyclo
