Full-quantification recycling method for bottom slag of garbage incinerator
The invention discloses a full-quantification recycling method for bottom slag of a garbage incinerator, and belongs to the technical field of solid waste resource utilization. According to the method, the garbage incinerator bottom slag is subjected to magnetic separation and vortex separation treatment, valuable metal in the garbage incinerator bottom slag is extracted, separation of a metal phase and a slag phase is achieved, the metal phase is recycled, and the slag phase is used for building materials in a high-valued mode. The slag phase is screened to obtain fine aggregate and coarse aggregate, the fine aggregate is subjected to ball milling activation and then compounded with cement clinker, limestone and gypsum, the mixture is evenly mixed to obtain an LC3 low-carbon cementing material, and the coarse aggregate and the LC3 low-carbon cementing material are used for high-performance water permeable bricks, heat preservation building blocks and concrete in a high-valued mode. All-component high-value utilization of the bottom slag of the garbage incinerator is achieved, and the method has the advantages of being short in process, free of pollution and easy to industrialize.
本发明公开了一种垃圾焚烧炉底渣全量化再生利用方法，属于固废资源化利用技术领域。本发明将垃圾焚烧炉底渣经过磁选、涡流分选处理，提取垃圾焚烧炉底渣中有价金属，实现金属相与渣相分离，金属相回收利用，渣相高值化利用于建材。渣相经筛分获得细集料和粗集料，细集料经球磨活化后复配水泥熟料、石灰石和石膏经混合均匀后得到LC3低碳胶凝材料，粗集料与LC3低碳胶凝材料高值化利用于高性能透水砖、保温砌块、混凝土。本发明实现了垃圾焚烧炉底渣全组分高值化利用，具有流程短、无污染、易于产业化的优点。
