摘要
开展镁熔砣余热回收技术的研究,对革新我国菱镁矿熔炼工艺、实现新形势下的节能减排具有十分重要的意义。在分析总结已有的镁熔砣余热回收技术的基础上,设计出了一体式镁熔砣余热回收窑,利用往复炉排进行逆流换热,将余热回收和物料预热一体化,系统简单,同时减少了能量损失,余热回收效率达30.37%,具有广泛投入使用的价值。
Carrying out research on waste energy recovery technologies about magnesium melting lumps is important significance for innovation of magnesite melting process and achieving energy con-servation and emissions reduction in new situation.Based on analyzing and summarizing the existing technology about waste heat recovery of magnesium melt, the integrated kiln for waste heat recovery of magnesium melting was designed.By using reciprocating grate transportation, this design accomplished cooling process of magnesium melting and preheating process of magnetite simultaneously, and it sim-plified the system.Meanwhile, it can reduced the loss of energy, and its efficiency of waste heat recov-ery was 30.37%, valuable for putting into use.
