Ceramsite and preparation method thereof
The invention relates to ceramsite and a preparation method thereof, and the preparation method comprises the following steps: (1) mixing anaerobic fermentation biogas residue with fly ash to obtain a first mixture; mixing the first mixture with water to obtain a second mixture; (2) carrying out hydrothermal reaction on the second mixed material, and dehydrating the reacted material to obtain a dehydrated solid phase; (3) pyrolyzing sludge to obtain pyrolyzed biochar, and mixing the pyrolyzed biochar with the dehydrated solid phase to obtain a third mixture; (4) performing granulation molding on the third mixture to obtain granules, and drying the granules to obtain dried granules; and (5) carrying out high-temperature roasting on the dried granules, and then cooling to obtain the ceramsite. The ceramsite preparation method disclosed by the invention is simple and practical, low in equipment investment and low in cost, and the obtained ceramsite is high in strength, has the effects of heat preservation, heat insulation, heat insulation and sound insulation as a building material, has fire resistance, shock resistance and durability, and has good economic benefits and environmental benefits.
本发明涉及一种陶粒及其制备方法，包括以下步骤：(1)将厌氧发酵沼渣与飞灰混合，得到第一混合料；第一混合料与水混合，得到第二混合料；(2)将所述第二混合物料进行水热反应，反应后的物料进行脱水，得到脱水固相；(3)将污泥热解得到热解生物炭，再与所述脱水固相混合，得到第三混合料；(4)将所述第三混合料造粒成型，得到颗粒料，再将颗粒料进行干燥，得到干燥颗粒料；(5)将所述干燥颗粒料进行高温焙烧，然后进行冷却，得到陶粒。本发明所述的陶粒制备方法简单实用，设备投资少，成本低，得到的陶粒强度高，作为建筑材料发挥保温、隔热、隔热、隔音效果，同时具有耐火、抗震、耐久性，具有良好的经济效益与环境效益。
