【摘要】 以翻车卸料过程为研究对象,结合翻车工艺流程和翻车机室结构特点建立粉尘控制模型,采用吹吸气流从源头对开放性粉尘进行控制,给出了控制参数的计算方法,对控制结果进行了CFD模拟。模拟结果表明,吹吸气流能从源头对粉尘进行有效控制,工作区粉尘相对质量分数由78%降至9%,粉尘控制率为85%～90%。更多还原

【Abstract】 Taking the unloading process of car dump as the research object,a dust control model is set up combined with the overturned process and the dumper chamber structure characteristics,in which the push-pull flow is adopted to control the openness dust from the source,the control parameters calculation method is given and the results of the model are simulated by CFD.Simulation results show that the push-pull flow can effectively control the dust from the source,the relative concentrations of dust the work area decreases from 78% to 9% and dust control rate from 85% to 90%.更多还原
