摘要
通过分析山西某煤矿现有主要通风机辅助设备扩散器的结构型式,借助CFD工具FLUENT进行数值模拟得出“当前扩散器的能量回收和扩散效率作用效果很不理想”的结论,由于受用地条件的限制,直立式扩散器结构不能改变,根据气流流动特点,提出改变扩散器导流板的数量和布局的方案。通过研究模拟,发现拆除原有1号和6号导流板后的4片导流板结构的扩散器在动能回收和扩散效率上性能最优,具有良好的应用价值。
By analyzing the structure of the diffuser of the main ventilator auxiliary equipment in a coal mine in Shanxi Province,with the help of CFD tools FLUENT numerical simulation,it is concluded that the energy recovery and diffusion efficiency of the diffuser is not ideal and can not be changed due to land use conditions.Due to the limitation of land use conditions,the structure of vertical diffuser can not be changed.According to the characteristics of airflow flow,a scheme to change the number and layout of diffuser guide plate is put forward.It is found that the diffuser with 4 plates after removing No.1 and No.6 deflector the plates has the best performance in kinetic energy recovery and diffusion efficiency.
