Cement clinker shock cooling process adopting material layer self-protection technology
The invention discloses a cement clinker shock cooling process adopting a material layer self-protection technology. An original third-generation grate cooler shell is dismounted and overall replaced with a LANE type tail-mounted rolling fourth-generation grate cooler; all fans are newly purchased, a waste heat power generation air pipe and a coal mill air pipe are installed between a settling chamber above the grate cooler and a mill air inlet, and an auxiliary air pipe is additionally arranged on a waste air pipeline. The cement clinker shock cooling process has the advantages that a large-area fixed grate bed, a thick material layer and an air volume adjusting valve are arranged, clinker shock cooling is truly achieved, and the clinker quality is improved while the cooling effect is guaranteed; the heat efficiency is improved by 2%, and the corresponding coal consumption is greatly reduced; the heat recovery effect is improved, and the middle air temperature is greatly increased.
本发明公开了一种采用料层自保护技术的水泥熟料骤冷工艺，拆除原三代篦冷机壳体，整体更换为LANE型尾置辗破第四代篦冷机；风机全部新购，余热发电风管，煤磨风管安装在篦冷机上方沉降室和磨机进风口之间，余风管道增加辅助风管。本发明具有大面积固定篦床+厚料层+风量调节阀，真正实现熟料骤冷，保证冷却效果的同时提高熟料质量；热效率提高2％，对应煤耗大大降低；热回收效果提高，大幅度提升中间风温的优点。
