| 摘 要： | 在实验的基础上,得到了计算单个颗粒惯性碰撞收集效率的经验方程式。结果表明,气溶胶粒子的粒径越大,惯性碰撞越显著;气体流速的增加有利于粒子的惯性沉积;沙介质的粒径越小,气溶胶粒子的惯性碰撞效应越高,穿透率也就越低。

| Abstract: | The empirical equation of single granule collection efficiency by impaction was established based on the experiments. Results showed that the bigger the diameter of aerosol particle was, the bigger the inertial impaction deposition. The inertial deposition of aerosol particle increased with the increasing of gas velocity. The smaller the diameter of filtration medium was, the bigger the inertial deposition and the smaller the filtration efficiency. |
