| 摘 要： | 利用FLUENT数值模拟软件,先用DPM离散相模型对不同粒径的粉尘颗粒在除尘洗气机的叶轮叶片中的运动轨迹进行了模拟,选取并分析了3种有典型粒径的粉尘颗粒对除尘洗气机造成的冲蚀磨损情况,发现磨损最严重区域出现在叶片吸力面尾缘、导流片及筒体与排风口面的夹角处,得出粉尘颗粒粒径大小对洗气机磨损的影响规律.

| Abstract: | FLUENT software is used to carry out the numerical simulation on the motion trajectory of different-diameter solid particles in the dust removing and washing machine with discrete phase model. Three representative different-diameters solid particles are chosen to consider erosion of dust removing and washing machine after analysis results. Most serious erosion areas are found to be in trailing edge of blade suction surface,inducer,and the angle between the cylinder and the exhaust surface,and the erosion laws of different-diameters particles on the dust removing and washing machine are obtained,which is useful for determining more effective anti-wear measures. |
