| 摘 要： | 运用ANSYS 12.0有限元分析软件包作为计算平台,针对实际尺寸范围内的熟料颗粒和实际风速范围内某些典型情况,对篦冷机骤冷区熟料内部的温度分布进行模拟表征。按照数值模拟计算数据,可显示出以下的结果:在骤冷过程中,熟料颗粒的表面温度首先降低,并且下降得比料球内部温度要快得多。在150s内,若风速相同,料径越大,料球内部的温度下降趋势越平缓;若料径相同,风速越大,料球内部的温度下降趋势越陡。模拟计算结果将为骤冷区内熟料的冷却控制提供有益的参考。

| Abstract: | The ANSYS 12.0 software package based on FEM(Finite Element Method) is used as a numerical computation platform,to simulate the temperature profile in clinker,within the range of actual clinker size and air cooling speed.According to the numerical simulation computation,the following results are shown: The surface temperature of clinker particle is decrease earlier and much faster than the temperature within clinker.If air cooling speed is same,the greater clinker size,the slower the trend of temperature decreasing within clinker;if clinker size is same,the greater air cooling speed,the steeper the trend of temperature decreasing within clinker in 150 seconds.The numerical simulation results of this paper may provide instructive references for controlling of clinker cooling process in QRC(quenching recuperation cooling) zone. |
