介绍了除尘箱的结构组成、功能原理,将隔板、除尘滤芯视为多孔介质,建立了除尘箱流体动力学分析模型,采用基于压力的隐式求解方法,对除尘箱内部气体流场进行了仿真,为锚杆钻车除尘系统降噪研究奠定了基础。
The structure and function principle of the dust box are introduced. The partition plate and the dust filter are considered as porous media. The fluid dynamics analysis model of the dust box is established. Based on the pressure implicit method, the gas flow field inside the dust box is determined Simulation, for the drilling rig dust removal system laid the foundation for the study of noise reduction.
