Sulfur-fixing ash ceramsite and preparation method thereof
The invention belongs to the field of sintered solid waste building materials, and particularly relates to sulfur-fixing ash ceramsite and a preparation method thereof. The sulfur-fixing ash ceramsiteis prepared from, by mass, 9-59 parts of sulfur-fixing ash, 20-66 parts of sludge, 8-33 parts of magma soil, 4-10 parts of perlite tailing powder, 1-4 parts of aluminum ash, 1-4 parts of limestone powder, 2-8 parts of glass powder, and 4 parts of a phosphate adhesive. The method comprises the following steps: dehydrating sludge until the water content is 17-56%, drying sulfur-fixing ash and aluminum ash by using waste heat, mixing all the powder materials according to a mass ratio, spraying a phosphate adhesive to obtain a wet mixture, aging the wet mixture, carrying out vacuum pugging extrusion granulation, drying a ceramsite blank, and finally performing roasting and screening to obtain the sulfur-fixing ash ceramsite. The high-temperature sintering characteristic of the sulfur-fixing ash is fully utilized, the resource utilization rate of the sulfur-fixing ash is increased, and cooperative treatment of multiple solid wastes is achieved. The prepared sulfur-fixing ash ceramsite canbe widely applied to building materials.
本发明属于烧结固废建筑材料领域，具体涉及固硫灰陶粒及其制备方法，按以下原材料质量份数比和工艺制备而成：固硫灰9～59份，污泥20～66份，岩浆土8～33份，珍珠岩尾矿粉4～10份；铝灰1～4份；石灰石粉1～4份；玻璃粉2～8份；磷酸盐胶黏剂4份。首先对污泥进行脱水至含水率17％～56％，采用余热对固硫灰、铝灰烘干，并按质量比混合所有粉料并喷混磷酸盐胶粘剂获得湿混料，然后陈化、真空练泥挤出造粒、烘干陶粒坯料，最后焙烧和筛分获得固硫灰陶粒。本发明充分利用固硫灰的高温烧结特性，提高固硫灰的资源化利用率，实现多固体废弃物协同处置。制备的固硫灰陶粒可广泛应用于建筑材料。
