Cyanided sludge sintering cyanogen removal process, cyanide-free brick, cyanided sludge sintering cyanogen removal system and application
The invention provides a cyanided sludge sintering cyanogen removal process, a cyanide-free brick, a cyanided sludge sintering cyanogen removal system and an application, and particularly relates to the technical field of cyanide sludge treatment and utilization. According to the cyanided sludge sintering cyanogen removal process, cyanided sludge and combustible materials are mixed and molded and then sintered to remove cyanogen, and a cyanide-free brick is obtained. The cyanided sludge and the combustible materials are preferably mixed according to the mass ratio of (70-95):(5-30), the oxygen concentration is greater than 10% during sintering cyanogen removal, the sintering cyanogen removal temperature is 950-1100 DEG C, the pressure is -100-0 Pa, and the sintering cyanogen removal time is 24-36 hours. According to the cyanided sludge sintering cyanogen removal process provided by the invention, the cyanide removal rate reaches 99.9% or above, waste heat of a sintering kiln is secondarily utilized in the process, and the comprehensive energy consumption and the treatment cost are low; in the process, the mechanical automation degree is high, the final product is harmless to the environment, the cyanide-free brick with economic value is obtained, and the method is suitable for large-scale application in the field of cyanidation tailing treatment in industries such as gold and the like.
本发明提供一种氰化污泥烧结除氰工艺、无氰砖、氰化污泥烧结除氰系统及应用，具体涉及氰化物污泥处置利用技术领域。该氰化污泥烧结除氰工艺，是将氰化污泥与可燃物混合成型后烧结除氰，并得到无氰砖。氰化污泥与可燃物优选按照70~95:5~30的质量比混合，烧结除氰时氧浓度大于10%，烧结除氰的温度为950~1100℃，压力为‑100~0Pa，时间为24~36h。本发明提供的氰化污泥烧结除氰工艺，氰化物去除率达到99.9%以上，过程中烧结窑的余热二次利用，综合能耗和处置成本低；过程中机械自动化程度高，最终产物对环境无害，得到了具有经济价值的无氰砖，适合在黄金等行业氰化尾渣治理领域大规模使用。
