1、年产6万吨环氧树脂车间工艺设计—毕业设计论文年产6万吨环氧树脂车间工艺设计设计说明:环氧树脂生产工艺一般分为一步法和二步法。目前低分子量液体环氧树脂和中分子量固体环氧树脂,一般都采用一步法工艺;高分子量环氧树脂采用二步法。本设计用一步法工艺:把双酚ABPA和环氧氯丙烷ECH在氢氧化钠作用下进行缩聚,即开环和闭环在同一反应条件下进行的工艺方法。以双酚A(BPA)为主要原材料,合成的环氧树脂称为双酚A(BPA)型环氧树脂,是目前产量最大、用途最广的环氧树脂,由于它的应用遍及国民经济的众多领域,因此又称为
2、通用型环氧树脂。本设计用此类环氧树脂。本文从生产工艺技术、经济、管理等方面对年产6万吨环氧树脂进行了详细的论述,内容主要包括:设计依据,工艺路线论证,工艺流程设计,全流程物料衡算,全流程能量衡算,工艺设备选型与计算,车间布置设计,三废处理及其综合利用等。设计主要成果如下:每天产量理论值181.82t,实际产量为180.70t;实际年产量为5.96万吨。用水蒸气加热的50000L闭式搅拌溶解釜;用冰盐水冷却的50000L搪玻璃闭式搅拌反应釜,材料为镍铬不锈钢0Cr18Ni9。主要设备:浆式搅拌器;标准
