PAC PAC is a solid with a liquid spray drying or drum drying to obtain the spray drying is an ideal drying method, suitable for mass production, and the production of smaller producers using roller drying is feasible . PAC’s current production methods are aluminum (including aluminum ash, lead slag), activated aluminum hydroxide method, aluminum oxide (including bauxite, coal, etc.), crystallization of aluminum chloride method and so on. This paper describes the physical and chemical properties of inorganic coagulant PAC, applications, introduced gray aluminum production process PAC, and the prospect of future research priorities and the development direction of the PAC.Keywords: PAC; development direction; technology research目 录年产5万吨无机絮凝剂聚合工段工艺设计 I摘 要 IAbstract II1绪论 11.1概述 11.1.1无机絮凝剂简介 11.1.2无机絮凝剂的基本物性 11.1.3国内外的现状及发展前景 21.2设计依据 21.3指导思想 21.4厂址的选择 31.5节能与环境保护 31.5.1节能 31.5.2环境保护 31.6安全防火 31.6.1消防设施 31.6.2灭火程序 42 工艺论证 52.1工艺原理 52.1.1生产方案 52.1.2 工艺路线 52.1.3工艺流程 52.1.4反应原理 52.2无机絮凝剂的生产技术 62.3发泡无机絮凝剂技术工艺比较 62.3.1塔式本体聚合技术 62.3.2添加少量溶剂的单釜连续本体聚合技术 72.3.3苯乙烯的悬浮聚合 72.3.4苯乙烯种子法悬浮聚合 72.4发泡无机絮凝剂生产工艺 82.4.1一步法聚合工艺 82.4.2二步法聚合工艺 82.4.3一步法工艺与二步法工艺的比较 82.5聚合氯化铝无机絮凝剂基本性能 92.5.1力学性能 92.5.2绝热性能 92.5.3化学性能 93 聚合工段工艺和生产流程 113.1聚合工段工艺过程叙述 113.2生产流程 113.3产品规格、原料及公用工程条件 113.3.1产品规格 113.3.2生产方式及规模 123.3.3原料 123.3.4工艺控制条件 134 物料衡算 154.1计算依据 154.2聚合工段物料衡算 154.2.1进料阶段 154.2.2出料阶段 165 聚合工段热量衡算 186 设备计算 216.1聚合釜的设计 216.1.1聚合基本数据 216.1.2聚合釜容积确定 216.1.3聚合釜的选型原则 216.1.4釜的选择 216.1.5聚合釜搅拌器的设计 236.2泵的设计 246.2.1计算依据 246.2.2管内流速的计算 246.2.3直管阻力和局部阻力损失的计算 256.2.4确定泵轴功率 256.2.5泵的选型 256.3换热器的设计 256.3.1设计依据 256.3.2计算总传热系数 266.3.3计算传热面积 276.3.4工艺结构尺寸 27参考文献 28附录1 设备一览 29谢 辞 31
