摘要

In order to make a reasonable dry-type dust removal plan of the coal transit spot in a coal washery,it is essential to install the dust removal fan and guide chute.Bymeans of the numerical simulation,the pollution mechanism at a transit point and the flow-field interior dust removal system had been analyzed.The result shows that the dustpollution at transit spot is mainly cased by the joint effort of induced airflow andshock-wave.With the appropriate dust removal fan and the guide chute,will effectively eliminate the positive pressure by gave rise to by the impact of falling coal,also avoid the secondary pollution.
