摘要

摘要: 含油钻屑经过萃取脱油后，通过马弗炉模拟水泥窑协同处置的方式对萃余钻屑开展实验研究。采用热重分析萃余固废掺入对水泥烧成过程的影响，结果表明：掺加萃余固废后，CaCO₃分解温度下降13.2℃，更有利于水泥熟料的烧成；通过乙二醇代用法测定水泥熟料中f-CaO含量，可得掺加萃余固废的最适比例为20%；水泥熟料的X射线衍射图谱结果表明，掺加萃余固体废物烧制的水泥熟料主要矿物组成不变，但萃余固体的掺加对水泥矿物形成仍有影响。水泥产品的水化样XRD图谱结果表明，萃余固体废物掺加会抑制水泥水化反应的速率，并且掺加萃余固体废物的水泥协同处置产品的重金属浸出浓度符合GB 30760—2014《水泥窑协同处置固体废物技术规范》的安全限值，无重金属浸出的环境安全风险。

Abstract: After the oil-bearing cuttings were extracted and degreased, the extracted raffinate cuttings were experimentally researched by the muffle furnace to simulate the co-processing of the cement kiln. Through the thermo-gravimetric analysis of the effect of extracted raffinate cuttings’ addition on the roasting process of cement, the results showed that after adding extracted raffinate cuttings, the decomposition temperature of calcium carbonate decreased by 13.2℃, and the addition of extracted raffinate cuttings was beneficial to making cement clinker. By measuring the content of f-CaO in cement clinker using ethylene glycol substitution method, it could be concluded that the proportion of solid waste added of 20% was the most suitable; the results of X-ray diffraction spectrum of cement clinker showed that the main mineral composition of cement clinker roasted with extracted raffinate cuttings was unchanged, but the addition of raffinate solids still affected the formation of cement minerals. At the same time, the results of XRD patterns of hydration samples of cement products showed that the addition of extracted raffinate cuttings would inhibit the cement hydration reaction rate, and the leaching concentration of heavy metals in cement co-processing products with extracted raffinate cuttings complied with safety limit of Technical Specification for Co-processing Solid Waste in Cement Kilns (GB 30760—2014), possessed no environmental safety risk of heavy metal leaching.
