Method for preparing ceramsite from incineration disposal residues
The invention discloses a method for preparing ceramsite by utilizing incineration disposal residues, which comprises the following steps of: uniformly mixing the incineration disposal residues, coal slime and a soft soil curing agent, granulating, drying and roasting to obtain the ceramsite. According to the method, the incineration disposal residue solid waste is matched with small molecules volatilized in the high-temperature solid-phase reaction process of the coal slime and the soft soil curing agent for puffing and pore-forming, meanwhile, a vitreous phase is formed, high mechanical properties are obtained while heavy metal curing is achieved, and the prepared ceramsite is low in volume weight, high in strength and good in comprehensive performance. The method can be widely applied to the fields of engineering construction, chemical engineering and the like.
本发明公开了一种利用焚烧处置残渣制备陶粒的方法，该方法是将焚烧处置残渣、煤泥及软土固化剂依次经过混匀、造粒、干燥和焙烧，即得陶粒。该方法利用焚烧处置残渣固废搭配煤泥和软土固化剂的高温固相反应过程中挥发的小分子进行膨化造孔，同时形成玻璃质物相，在实现重金属固化的同时，获得较高的力学性能，且制备的陶粒容重较轻，强度高，可以广泛的应用于工程建筑、化工等领域。
