摘要 本设计的设计题目是日产5000吨水泥熟料水泥厂新型干法生产线烧成系统工艺设计The design of this topic is at the design capacity of over 5,000 tons of cement clinker production line of new dry cement kiln system process design. The design of the main content of the cement production process, the cement plant area and other layout and selection of the host device. Focus on the design of some of the kiln. This design uses a modern two tranches of the most advanced rotary kiln. I limited the design level, there are many problems in their design, I hope the teacher criticized the correction. 1. kilns choice: the choice of the kiln process, I calculate the theoretical formula used kiln, and I also find the actual manufacturer of the situation, finally, I set my combination of the two kiln; 2. the material balance calculation: According to Empirical formula (limestone saturation coefficient, rate of silicate, aluminum oxide ratio) calculated the appropriate values. Determine the final ratio of raw materials; 3. the production process design and equipment selection for the host computing: the material balance calculations based on previous results, combined with theoretical formula and selected examples drawn models. Key words: cement, dry process production line, rotary kiln, calcination 目录 前言 3 第一章 工艺设计的指导思想与原则 6 1.1指导思想 6 1.2设计原则 6 1.2.1根据计划任务书规定的产品品种、质量、规模进行设计 6 1.2.2主要设备的能力应与工厂规模相适应 7 1.2.3选择技术先进经济、合理的工艺流程和设备 7 1.2.4全面解决工厂生产、厂外运输和各种物料储备的关系 7 1.2.5注意考虑工厂建成后生产挖潜的可能和留有工厂发展余地 7 1.2.6合理考虑机械化、自动化装备水平 7 1.2.7重视消音除尘，满足环保要求 7 1.2.8方便施工、安装、方便生产、维修 8 第二章 配料计算 9 2.1 设计内容 9 2.2 原始数据 9 2.3 配料计算 9 2.3.1 确保熟料率值的组成 9 2.3.2 熟料热耗的确定 10 2.3.3 计算煤灰掺入量 10 2.3.4计算干生料的配合比 10 2.3.5 将干料配比折算成湿料配比 11 第三章 物料平衡表 12 第四章 工艺流程简述 13 4.1 原料工段 13 4.1.1石灰石开采与输送 13 4.1.2 石灰石预均化堆场 13 4.1.3 物料联合储库与输送 13 4.1.4 原料调配库及输送 13 4.1.5生料粉磨 13 4.1.6原煤破碎及输送 13 4.1.7煤粉制备 13 4.2 烧成工段 13 4.2.1窑磨废气处理系统 13 4.2.2生料均化库和窑喂料 13 4.2.3预热器系统 14 4.2.4窑中 14 4.2.5窑头熟料冷却及输送 14 4.2.6熟料储存 14 第五章 设备选型计算 15 5.1回转窑的计算 15 5.2窑头电收尘选型计算 16 5.3熟料破碎机选型 17 5.4熟料输送设备选型 17 参考文献 1
