Municipal sludge green energy-saving recycling brick making process
The invention discloses a municipal sludge green energy-saving recycling brick making process, and relates to the technical field of building material manufacturing, the municipal sludge green energy-saving recycling brick making process comprises the following steps: S1, sludge conditioning: adding functional fiber RPFA and a flocculant into sludge; the conditioning time is 10 to 120 minutes; s2, raw material treatment, wherein coal gangue, bauxite tailings, building waste residues and shale are smashed, and the fineness is controlled to be 1-3 mm; s3, mixing the materials: mixing the materials obtained in the steps S1 and S2, and uniformly stirring; s4, blank making: aging the mixture obtained in the step S3; and S5, brick making: drying and roasting the green bricks aired in the step S4 by using a drying kiln and a tunnel kiln, and cooling to obtain a finished product. In the sludge conditioning process, the functional fiber RPFA short fiber is added to serve as a sludge framework material, the electric charge neutralizing effect is achieved, meanwhile, the effects of bacteriostasis, deodorization and heavy metal solidification are achieved, and the environment in the sludge storage, transportation and operation process is greatly improved.
本发明公开了市政污泥绿色节能资源化制砖工艺，涉及建筑材料制造技术领域，包括S1、污泥调理：向污泥中添加功能纤维RPFA和絮凝剂；调理时间10‑120min；S2、原材料处理：将煤矸石、铝土矿尾矿、建筑废渣土、页岩进行粉碎，控制细度在1‑3mm；S3、物料混合：步骤S1及S2所得混合并搅拌均匀；S4、制坯：对步骤S3所得混合物进行陈化；S5、制砖：利用干燥窑及隧道窑对步骤S4晾晒后的砖坯进行干燥并焙烧，冷却后获得成品。本发明在污泥调理过程中添加功能纤维RPFA短纤充当污泥骨架材料、中和电荷作用，同时起到抑菌、除臭、固化重金属作用，极大改善污泥存储、运输、操作过程环境。
