摘要:
采用计算机流体力学(CFD)理论中的离散相模型(DPM)对立轴冲击式破碎机内部复杂的气固两相流进行数值仿真,模拟立轴冲击式破碎机除尘装置除尘过程,探究除尘装置的除尘效果及最佳风机风量.以不同粒径的固体颗粒为入射源,分别从流场的速度、压强等方面讨论分析破碎机内部气固耦合作用,分析在除尘口风机不同风量下破碎机的除尘装置对不同粒径的颗粒的分离效果.结果表明:风机风量在最大值的40%~60%之间时,既能保证除尘装置的除尘效果,又能尽量避免粒径较大的颗粒被吸除.
Abstract:
A numerical simulation of gas-solid two phase flow in a vertical shaft impact crusher was conducted using a discrete phase model(DPM)of computational fluid dynamics(CFD)theory to simulate the dusting process and find an optimum capacity of the exhaust fan for best dusting. Particles with different diameters were set as injections to analyze the gas-solid coupling effect in the crusher from the aspect of speed and pressure, etc. respectively and analyze the dusting efficiency for different diameter particles while different blast capacity of exhaust fan act on dust outlet. The experimental results indicate that 40%-60% of maximum blast capacity of exhaust fan can ensure effective dusting and avoid suction of bigger particles.
