毕业设计（论文）-日产10000水泥熟料新型干法水泥厂烧成系统工艺设计（窑尾）.doc

摘要
现代最先进的水泥生产技术就是新型干法预分解窑。预分解窑是在悬浮预热器与回转窑之间增设分解炉,在分解炉中加入占总用量50%-60%的燃料,使燃料燃烧的过程与生料碳酸盐分解的吸热过程在悬浮状态或沸腾状态下迅速进行,从而使入窑生料的分解率从悬浮预热窑的30%-40%提高到85%-90%,使窑的热负荷大为减轻,窑的寿命延长,而窑的产量却可成倍增长。
为了符合当今水泥行业的发展需求同时也是对大学本科四年所学知识的考查,我选择了“日产10000吨水泥熟料新型干法生产线窑尾系统工艺设计”这个课题作为我的毕业课题。设计范围主要是窑尾系统,通过配料计算、工艺平衡计算等得出结果,并结合实际对主机及附属设备进行选型,进而对各种设备进行工艺布置,对全厂的设备进行简单规划。

ABSTRACT
Modern most advanced cement production technology is NSP kiln advance position. Pre position kiln is in suspension preheater between posing furnace with rotary kiln added, join in calciner in total amount 50% - 60% of fuel, to make the fuel burning process and raw in the absorption process pose carbonate state of suspension or boiling condition, thus make rapid position rate of kiln raw from suspension preheater kiln 30 to 40 percent of the increased to 85 percent to 90 percent, the heat load of kiln is reduced greatly, while the prolonging furnace production but can increase exponentially.
In order to meet the development needs of the cement industry today and at the same time examine the knowledge of university undergraduate course four years, I chose "nissan 10000 tons of cement clinker NSP production line preheater system process design" this topic as my graduation project. Preheater system design range is mainly by ingredients calculation, craft equilibrium calculation etc, and actual results to host and affiliated equipments, and selection of equipment, process arrangement of all the equipment simple planning.
Key words: Precalcining system;Firing system;Batching system;Griding system
