Cement clinker production admixture
The invention discloses a cement clinker production admixture, and belongs to the technical field of building material admixtures. The admixture is prepared from the following raw materials in percentage by weight: 1-5% of ferric chloride, 1-10% of ferric sulfate, 5-10% of urea, 3-5% of glycerol, 5-10% of composite anhydrous sodium sulphate, 5-10% of ammonium nitrate and the balance of water. Thecombustion efficiency and the cement clinker quality can be effectively improved by adding 1.4-1.6 per mill of the admixture disclosed by the invention into the pulverized coal mill. The admixture, urea and ammonium nitrate play a role in denitration and forging assistance, glycerin plays a role in increasing heat of the grinding aid, and ferric chloride catalyzes calcination of the cement clinker. Besides, anhydrous sodium sulphate and modified boron nitride achieve synergistic interaction, the purposes of energy conservation, emission reduction and efficiency improvement are achieved together, and the high-strength cement clinker is obtained. Meanwhile, the technical purposes of accelerating the firing speed, increasing the yield, saving the coal consumption, fixing sulfur, denitrating and reducing the cost are achieved, and wide economic benefits and social benefits are achieved.
本发明公开一种水泥熟料生产外加剂，属于建筑材料外加剂技术领域。本发明外加剂是由以下重量百分比的原料组成：氯化铁1‑5％、硫酸铁1‑10％、尿素5‑10％、甘油3‑5％、复合元明粉5‑10％、硝酸铵5‑10％、余量为水。通过在煤粉磨中加入1.4‑1.6‰的本发明添加剂，即可有效提升燃烧效率和水泥熟料质量。本发明外加剂，尿素和硝酸铵起脱硝助锻作用，甘油起助磨剂增加热量作用，氯化铁催化水泥熟料煅烧，此外元明粉和改性氮化硼，两者协同增效，共同实现节能减排增效的目的，得到高强度的水泥熟料，同时达到加快烧成速度、提高产量、节约煤耗、固硫脱硝，降低成本的技术目的，具有广阔的经济效益和社会效益。
