基于数值模拟对李楼铁矿破碎硐室粉尘治理的研究

Based on Numerical Simulation for Lilou Iron Ore Crushing Chamber Dust Control Research

根据李楼铁矿1#、2#破碎站所属硐室的实际布置方式,运用数值模拟对实际风流规律进行模拟分析,得出冲击风流随风筒压入破碎硐室内后速度略有增加,随后降低,在硐室空间内形成涡流.涡流内风速较小,保持在0.25 m/s以下.

According to 1#, 2# crushing station belongs to the actual arrangement of crushing chamber in Lilou iron ore, the simulation analysis carried out on the actual wind flow rule, it turned out that the speed of shock wind flow increases slightly, then decreases when it run into crushing chamber, meanwhile forming eddy in the cavern space. The wind speed within vortex is small, remaining below 0.25 rids.
