Method for comprehensively utilizing waste incineration fly ash and flotation tailings
The invention provides a method for comprehensively utilizing waste incineration fly ash and flotation tailings. The method comprises the following steps: uniformly mixing waste incineration fly ash with auxiliary raw materials, melting and homogenizing in a high-temperature state, carrying out water quenching on the molten glass is subjected to form glass granules, evenly mixing the glass granules and the wet-based tailings then conveying a drying machine, by waste heat generated by a garbage incinerator, drying the composite material of the glass granules and the wet-based tailings, conveying the dried material to a mill, and conveying the ground material to a finished product warehouse, so that the cement active mixed material is obtained. The flotation tailings are subjected to grading, concentration, dehydration, filter pressing and the like to obtain wet basis tailings, the waste heat generated in the waste incineration process is used for drying the composite material of the water-quenched glass granules and the wet-based tailings, so that the problem of tailing drying in the comprehensive utilization process of the tailings is solved, the overall activity of the composite material is improved, and the composite material meets related national standards.
本发明提供了一种垃圾焚烧飞灰与浮选尾矿综合利用的方法，包括以下步骤：将垃圾焚烧飞灰与辅助原料混合均匀后，在高温状态下熔融均化，熔融玻璃液水淬后形成玻璃粒料，将玻璃粒料与湿基尾矿混合均匀后输送至烘干机，利用垃圾焚烧炉产生的余热对玻璃粒料与湿基尾矿的复合料进行烘干，烘干后的物料输送至磨机，粉磨后的物料输送至成品库，即为水泥的活性混合材。浮选尾矿经过分级、浓缩、脱水、压滤等工序后得到湿基尾矿，利用垃圾焚烧过程产生的余热对水淬玻璃粒料与湿基尾矿二者的复合料进行烘干，此举不仅解决了尾矿综合利用过程中面临的尾矿烘干难题，还提高了复合物料的整体活性，使其满足相关的国家标准。
