Unfired ceramsite prepared from sludge incineration waste residues and preparation method of unfired ceramsite
The invention provides unfired ceramsite prepared from sludge incineration waste residues and a preparation method thereof.The unfired ceramsite is prepared from, by mass, 20-30 parts of sludge incineration waste residue particles, 25-35 parts of sludge incineration waste residue powder, 25-35 parts of cement, 3-6 parts of quick lime, 3-9 parts of binder and 0.5-1.0 part of calcium sulfate; the preparation method comprises the following steps: taking sludge incineration waste residue particles in sludge incineration equipment, cooling a part of the sludge incineration waste residue particles for later use, cooling and drying the other part of the sludge incineration waste residue particles, crushing, and sieving to obtain sludge incineration waste residue powder; sequentially adding the raw materials into a container, stirring and mixing, adding water, and continuously stirring and mixing uniformly to obtain mixed slurry; transferring the mixed slurry into a granulator, and granulating to obtain semi-finished granules; curing the semi-finished granules in a steam engine under normal pressure, taking out, continuously spraying water for curing for 2-3 days, and drying. The unfired ceramsite has the advantages of high hardness, many pores and good adsorbability.
本发明提供一种利用污泥焚烧废渣制备的免烧陶粒及其制备方法，按照质量份数计，免烧陶粒包括如下组份：污泥焚烧废渣颗粒20‑30份、污泥焚烧废渣粉末25‑35份、水泥25‑35份、生石灰3‑6份、粘结剂3‑9份、硫酸钙0.5‑1.0份；制备方法包括如下步骤：取污泥焚烧设备中的污泥焚烧废渣颗粒，一部分冷却后备用，另一部分冷却干燥后粉碎，过筛后得到污泥焚烧废渣粉末；将原料依次加入容器中，搅拌混合，加入水后继续搅拌混合均匀，得到混合浆料；将混合浆料转移至造粒机内，造粒得到半成品颗粒料；将半成品颗粒料在蒸汽机内常压养护，取出继续喷洒水分养护2‑3天，干燥后即可。本发明的免烧陶粒硬度高，孔隙多且吸附性好。
