运用七孔球探针对直切型旋风分离器及入口加挡板结构进行了流场的测量,并对其内部流场进行了研究,指出了随挡板角度变化,流场的变化规律,结果表明随挡板角度变大,切向速度提高,切向速度峰值位置沿径向外移,下行流的轴向速度提高,上行流的轴向速度降低.%Flow fields in tangential type cyclone separators were measured by means of seven-hole pitot tube. The results indicate that ,with angle of baffle plate increases, the tangential velocity increases and peak of the tangential velocity moves outward along the radial direction, the axial speed of the downward flow increases and the axial velocity of the upward flow reduces.
