Circulating fluidized bed fly ash as well as modification method and application thereof
The invention belongs to the technical field of industrial solid waste resource utilization, and provides circulating fluidized bed fly ash and a modification method and application thereof. The modification method comprises the following steps: mixing and grinding circulating fluidized bed fly ash and a grinding aid to obtain intermediate fly ash; and mixing and grinding the intermediate fly ash and an activating agent, and finishing modification to obtain the modified circulating fluidized bed fly ash. According to the invention, the fly ash of the circulating fluidized bed is successfully modified in a composite modification mode of combining physical grinding and the modifier. In the grinding process, octylene glycol and calcium lignosulphonate are added, and the grinding aiding effect is generated through adsorption between heterogeneous substances; a grinding aid is matched with a physical grinding process to improve the distribution particle size of the fly ash; according to the invention, the compound activating agent is adopted to perfect surface defects and improve a loose and porous structure, the circulating fluidized bed fly ash can be applied to the field of building materials, the resource utilization of the fly ash is improved, land accumulation is reduced, and economic benefits and environmental protection values are achieved.
本发明属于工业固体废弃物资源化利用技术领域，提供了一种循环流化床飞灰及其改性方法和应用。该改性方法包含下列步骤：将循环流化床飞灰和助磨剂混合研磨，得到中间飞灰；将中间飞灰和活化剂混合研磨，完成改性得到改性循环流化床飞灰。本发明通过物理研磨和改性剂结合的复合改性方式，成功的对循环流化床飞灰进行改性。本发明在研磨过程中加入了辛二醇和木质素磺酸钙，异类物质间的吸附从而产生了助磨效果；助磨剂配合物理研磨的工艺改善了飞灰的分布粒径；本发明采用复配的活化剂完善表面的缺陷、改善疏松多孔的结构，可以将循环流化床飞灰运用到建筑材料领域中，提高飞灰的资源化利用，减少土地堆积，具有经济效益和环保价值。
