齐 齐 哈 尔 大 学 毕业设计（论文） 题 目 年处理500吨玉竹提取车间初步设计 学 院 化学与化学工程学院 专业班级 制药工程061班 摘 要 ；提取；车间设计 Abstract The topic of this design is “the preliminary design process of yearly produced 500 ton jade bamboo extraction workshop”, The most effective ingredients in jade bamboo，such as alkaloid glycosides, salt, salt and organic acids, amino acids, polysaccharide are easily desolved in water and alcohol,so in this design water extraction was used ,then concentrating the extract ,add proper ethanol for precipitating repeatedly to remove the insoluble substances,at last clear liguid was achieved from the experiment.,so water extract-alcohol method were adopted in this paper. The main task of this design is to choose a simple, economical, scientific, the innovated process which can complete annual capacity of 500 tons jade bamboo extraction . In addition materials and heat calculation, main equipments and public engineering calculation, three wastes treatment, factory site selection and workshop equipment layout and so on. are included .That is all, hand-painted process flow chart with control points workshop layout ,main equipments figure are needed,and the last two chart need use CAD to complete. Key words：Jade Bamboo；Extraction； Workshop Design 目 录 摘 要 I Abstract II 第1章 绪论 1 1.1 概述 1 1.1.1 生产方法简介 1 1.1.2 设计原则及要求 1 1.1.3 设计依据 2 1.1.4 车间概况 2 1.2 厂址选择 3 1.2.1 厂址选择原则 3 1.2.2 建厂条件 3 1.2.3 方案比较 4 1.3 原材料、产品主要技术规格 5 1.3.1 原材料技术规格 5 1.3.2 产品技术规格 5 1.4 原材料消耗定额及消耗量 5 第2章 工艺流程设计 6 2.1 生产方法选择 6 2.1.1浸渍法提取工艺 6 2.1.2渗漉法浸提工艺 7 2.1.3煎煮法浸提工艺 7 2.1.4回流提取法 7 2.2 工艺流程示意图 7 2.3 工艺流程叙述 8 2.3.1提取工段 8 2.3.2减压浓缩工段 8 2.3.3醇沉工段 9 2.3.4乙醇回收 9 第3章 化工计算 10 3.1 物料计算 10 3.1.1 提取工段的物料计算 10 3.1.2 浓缩工段物料衡算 13 3.1.3 醇沉工段物料衡算 13 3.1.4 乙醇回收工段物料衡算 14 3.2 设备工艺计算 15 3.3 热量计算 17 3.3.1 多功能提取罐热量计算 18 3.3.2 双效浓缩器热量计算 19 3.3.3 醇沉段热量计算 20 3.3.4 乙醇回收塔热量计算 21 第4章 主要设备设计 22 4.1 基础数据 22 4.2 计算 22 4.2.1 体积计算 22 4.2.2
