Technology for preparing active powder from multi-source coal-based solid waste
The invention provides a technology for preparing active powder from multi-source coal-based solid waste, and belongs to the field of solid waste resource utilization. The environment problems that industrial solid waste pollutes water and occupies land resources can be effectively solved, the powder material with high activity is prepared, and the method is an application technology which saves energy, recycles resources and is green and environment-friendly. The multi-source coal-based solid waste is used as a raw material to be subjected to mechanical and chemical synergistic activation, the adopted composite excitant is sodium silicate and sodium hydroxide, and the mixing amount of the composite excitant is obtained by compounding according to a sorted compounding method. According to the technology, the multi-source coal-based solid waste is adopted as a raw material, and the three solid wastes including desulfurized gypsum, gasified slag and fly ash are activated and utilized at the same time, so that the utilization efficiency of the coal-based solid waste is comprehensively improved, and value-added utilization is realized.
本发明提供一种利用多源煤基固废制备活性粉体的技术，属于固废资源化利用领域。可有效解决工业固废污染水体，占用土地资源等环境问题，制备具有高活性的粉体材料，是一项节约能源、资源循环利用、绿色环保的应用技术。以多源煤基固废为原料对其进行机械与化学协同活化，采用的复合激发剂为硅酸钠和氢氧化钠，复合激发剂的掺量根据整理出的复合方法进行复合得出。本发明采用多源煤基固废为原料，将脱硫石膏、气化渣、粉煤灰三种固体废物同时进行活化利用，全面提升煤基固废利用效率，实现增值化利用。
