摘要
基于旋风分离器设计计算的Muschelknautz模型和工业现场回转窑窑尾排放烟尘粒径数据,从理论角度分析了旋风分离器设备本体结构、气流入口截面尺寸及气流温度等因素对气固分离效率所产生的影响。综合施工周期、施工难度等因素,采取将入口截面积缩小39%,优化流道结构来消除紊流等改造措施,最终将旋风分离器收尘效率提高10%以上,同时出口烟尘颗粒累积分布粒度降低10.00μm以上,达到了预期效果。
Based on the Muschelknautz model and the soot particle size distribution data from industrial rotary kilns, the influence of cyclone＇s mechanical structure, airflow entrance＇s sectional size and airflow temperature on the gas-solid separation efficiency was analyzed theoretically. Considering construction period and difficulty there, the sectional size of entrance was reduced by 39% and the airflow channel was optimized to eliminate turbulent to improve cyclone＇ s dust-collecting efficiency by more than 10% along with a decreased soot particle granularity greater than 10. 00μm micrometer as expected.
