摘要
连续式石墨化炉生产的散装料温度可达2600℃,为研究高温散装料的强制冷却情况,运用Fluent软件对冷却器进行数值模拟,得到高温物料及冷却水的温度分布和流场分布。结果表明,冷却器出口处物料温度远低于指标要求,冷却效果显著。结合模拟结果分析物料入口速度和各级冷却水入口速度对温度的影响,得出各最佳冷却水入口速度,为进一步优化提供了参考依据。
The temperature of balk cargo graphite produced by continuous graphitizing furnace is 2600. In other to study the forced cooling situation of high temperature balk cargo, the numerical simu- lation was conducted on the optimized cooling unit by using the software Fluent. The temperature and flow distributions of the cooling process for graphite and cooling water were obtained. The results show that the temperature of balk cargo outlet is much lower than the requirement. The cooling effect is re- markable. According to the temperature and speed of water every inlet basic on simulation results, the best speed of water inlet is obtained, and the further optimization for optimized cooling unit is guided.
