摘要
研究了篦冷机内水泥熟料与空气的换热机理,并基于国内某5 000t/d水泥熟料生产线实际运行参数,利用多孔介质理论对篦冷机内传热过程进行了数值模拟,建立了篦冷机物理、数学模型,通过Fluent流体计算软件数值模拟研究了篦冷机内部温度场、压力分布、流场分布,重点分析了篦冷机中部取风口的温度与熟料层厚度的关系,根据模拟分析结果合理布置篦冷机各取风口位置及风量分配.
Abstract
The heat transfer mechanism between cement clinker and air in a grate cooler was studied,and based on the actual operating parameters of a 5 000t/d cement clinker production line in China,the heat transfer process inside the grate cooler was numerically simulated using porous media theory.A physical and mathematical model of the grate cooler was established,and the temperature field,pressure distribution,and flow field distribution inside the grate cooler were numerically simulated using Fluent fluid calculation software.The relationship between the temperature of the middle air intake of the grate cooler and the thickness of the clinker layer was analyzed in detail.Based on the simulation analysis results,the positions of each air intake of the grate cooler and the distribution of air volume were reasonably arranged.
