Research on openness dust control by push-pull flow in the process of freight train unloading

摘要：

　　Taking the unloading process of car dump as the research object,a dust control model is set up by combining the overturned process and the dumper chamber structure characteristics.The push-pull flow is adopted to control the openness dust from the source,the control parameters calculation method has been given and the results of the model have gone through the CFD simulation.The simulation results show that the push-pull flow can control the dust effectively from the source,the relative concentration of dust in the working area reducing from 78% to 9%,and the dust control rate is 85% to 90%.
