环冷机冷却过程节能优化仿真研究

Numerical Simulation and Research on Energy Saving in Cooling Process of Sinter Cooler

环冷机是高耗能设备,节能降耗方法优化一直是研究的重点。过去一直通过研究余热回收来达到节能的目的,现应选择合理的工艺参数及分区分量分配,为研究环冷机节能降耗提供了新方案。针对上述方案,借助FLUENT对环冷机内部传热过程进行数值仿真,研究冷却时间和鼓风机风量等工艺参数对烧结矿温度及处理能力的影响,进而得出对能耗的影响,然后采用正交试验法研究环冷机最优分区风量分配。研究表明,减少冷却时间可提高环冷机的处理能力;减少鼓风机台数可降低风机群组电能消耗;合理的分区风量分配可降低烧结矿排料温度,减轻皮带烧损,为环冷机节能降耗提供理论依据。

Sinter cooler is high energy - consuming equipment, and the method of energy saving has been regar- ded as the focus of research. In the past, waste heat recovery had been researched to achieve the goal of energy sav- ing. Now, choosing reasonable processing parameters and air volume distribution after dividing the sinter cooler be- come new scheme of energy saving. Contrapose the above scheme, the process of heat transfer in sinter cooler was simulated with FLUENT, and the influence on processing capacity and temperature of sinter was studied by adjusting cooling time and air volume of blowers and the influence on energy consumption was further studied. Then orthogonal test method was used to research the partial air flow adjustment of sinter cooler. As shown in the study, the process- ing capacity of sinter cooler can be improved after the cooling time down to a reasonable value; the energy consump- tion of blowers can be reduced after optimizing the number of blowers ; the final temperature of sinter and the damage of belt can be reduced by reasonable air volume distribution after dividing the sinter cooler. It can provide some basis and reference for energy saving of sinter cooler.
