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。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，我选择了“日产000吨水泥熟料窑尾设计”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 decomposition. Pre decomposition kiln is in suspension preheater between decomposing 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 decompose carbonate state of suspension or boiling condition, thus make rapid decomposition 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 目录 摘要 I ABSTRACT II 前言 1 第一章 工艺设计介绍 6 1.1指导思想 6 1.3全厂工艺流程 8 1.3.1原料工段 8 1.3.2烧成工段 9 第二章 配料计算 12 2.1窑的选型及标定 12 2.1.1窑的选型计算 12 2.1.2回转窑产量的标定 13 2.1.3窑的年利用率 13 2.2 煤灰掺入量确定 14 2.3 配料计算 14 2.3.1，原料化学成分 15 2.3.2 计算原料配合比： 15 2.3.3计算湿原料的配比： 16 2.4全厂物料平衡的计算 16 2.4.1原料消耗定额 17 2.4.2烧成用干煤消耗定额 17 2.4.3．含水湿物料的消耗定额 17 2.4.5 湿煤的消耗定额 18 2.5 10000t/d水泥熟料物料平衡表 19 第三章 储库计算 20 3.1石灰石预均化堆场的计算 20 3.2储库的选型计算 20 3.2.1石灰石配料库 20 3.2.2粘土配料库 20 3.2.3铁粉配料库 20 3.3生料均化库的计算 20 3.4熟料库的选取与计算 20 第四章
