摘要
以旋风分离器内部流场模拟分析为基础,分别对1、30、100μm三种不同粒径的煤粉与滑石粉在分离器中的颗粒轨迹做了分析,首先得出其内部流场速度方向及大小的分布规律,从内部气流走势上看,分离器具有不对称性;从速度矢量图颜色上看,在分离器中心部分的气流具有强烈旋转,气流在壁面附近的位置速度快速降低。再得出不同粒径颗粒在分离器中的轨迹分布规律。为进一步的研究及改进旋风分离器的性能有参考意义。
Based on simulation analysis of internal flow field in the cyclone separator, particle trajectories of 1,30,100 μm coal powder and talcum powder in the cyclone separator were analyzed, the distribution law of speed direction and speed value in the internal flow field was obtained. The internal air flow direction shows that the separator has asymmetry; the velocity vector chart color shows that air flow in the center part has a strong rotation in the cyclone separator, the speed of the air flow near the wall reduces rapidly. On the other hand, the distribution law of different size particle trajectory in the separator was obtained.
