Carbonization product production device and preparation method for recovering CO2 and smelting waste residues
The invention discloses a production device and a preparation method of a carbonized product for recovering CO2 and smelting waste slag, which integrates carbon dioxide recovery, metallurgical waste slag dissolution and dispersion, carbonization, product regulation and control, product monitoring, suction filtration and drying, modifies the metallurgical waste slag by a wet carbonization process, and disperses CO2 to maintain the overall reaction uniformity of wet carbonization. Adjusting and controlling the crystal form of a carbonized product and monitoring the pH value of the product, then filtering and drying, screening to a proper particle size, and then co-doping with cement to prepare the green gelling material. The method is simple in process and high in operability, the carbonization degree of the metallurgical waste residues is effectively improved, the cost is greatly reduced, and the prepared metallurgical waste residue cementing material is high in strength, good in carbon sequestration performance, low in production cost, low in carbon and environmentally friendly.
本发明公开了一种回收CO2和冶炼废渣的碳化产物生产装置及制备方法，将二氧化碳回收、冶金废渣溶解分散、碳化、调控产物、监测产物、抽滤及烘干融为一体，将冶金废渣以湿法碳化的工艺进行改性，分散CO2保持湿法碳化整体的反应均匀度，调控碳化产物晶型和监测产物pH，然后进行过滤烘干，并筛分至合适粒径，再与水泥复掺制备成绿色胶凝胶凝材料。本发明工艺简单，可操作性强，有效提升了冶金废渣的碳化程度，成本大大降低，制备的冶金废渣胶凝材料强度高、固碳性能好、生产成本低及低碳环保。
