Environment-friendly incineration ash recycling method
The invention relates to an environment-friendly incineration ash recycling method, which belongs to the technical field of incineration ash treatment equipment, and comprises the following steps of: pretreating untreated ash, firstly, carrying out particle screening on the ash, and removing stones, bricks, ceramic fragments, glass fragments and other metal particles; then, treating and removing ferrous metal by using strong magnetic equipment, and after magnetic separation, performing a washing chloride ion removal process on the ash, so that chloride ions and heavy metal are leached out through washing treatment; filtering the ash water subjected to water washing treatment, dehydrating the ash water by filter press equipment to form an ash cake, crushing the ash cake, and heating, baking and dehydrating the ash cake; mixing the pretreated ash with an environment-friendly baking-free brick, putting the stirred mixture into a brick mold, carrying out compression molding by using a hydraulic machine, demolding, and naturally curing to obtain the finished baking-free brick. The method has the characteristics of high utilization rate, energy conservation, environmental protection and good application stability. The problem of how to recycle the incineration ash is solved.
本发明涉及一种环保型焚烧灰渣循环利用方法，所属焚烧灰渣处理设备技术领域，包括对未经过处理的灰渣进行预处理，首先对灰渣进行颗粒筛选，将石头、砖块、陶瓷碎片、玻璃碎片及其他金属颗粒去除。接着利用强磁力设备处理去除黑色金属，磁力分选后将灰渣进行水洗去氯离子过程，使得氯离子和重金属通过水洗处理浸出。水洗处理后的灰渣水进行过滤，先进行压滤机设备进行脱水形成灰渣饼，接着灰渣饼破碎后进行加热烘烤脱水。将预处理后的灰渣进行环保免烧砖的混料制作，搅拌完的混合料投入砖模用液压机械压制成型，脱模自然养护后即出成品免烧砖。具有利用率高、节能环保和运用稳定性好的特点。解决了如何将焚烧灰渣进行循环利用的问题。
