摘　　要：煤矸石是煤炭开采和洗选过程中产出的主要固体废弃物。为大规模消纳煤矸石生产建筑材料并产生可观经济效益,开发高效煤矸石脱碳活化工艺至关重要。基于立式脱碳设备设计了一种煤矸石自热式脱碳生产工艺,并投入正常生产。生产工艺无须外加燃料即可实现对粒径为5~50 mm、不同热值的煤矸石脱碳活化,年处理煤矸石20万t。生产的脱碳煤矸石性能参数优于GB/T 2847-2022《用于水泥中的火山灰质混合材料》要求,可用于水泥掺合料或部分替代水泥熟料,具有广阔的市场前景。Coal gangue is the main solid waste discharged during coal mining and washing processes.Developing efficient decarbonization and activation processes for coal gangue are critical to producing building materials on a large scale and generating considerable economic benefits.Anhui Huaihai New Materials Co.,Ltd has designed a self-heating decarbonization production process based on coal gangue vertical decarbonization equipment,and put it into regular production.This process can achieve decarbonization and activation of coal gangue with particle size of 5~50 mm and different calorific value with no need for additional fuel,and consume 200000 tons of coal gangue annually.The produced decarbonized coal gangue has superior performance parameters than the requirements of GB/T 2847-2022,and can be used as cement admixture or partially replace cement clinker with broad market prospects.
