1 绪论
1.1 课题研究的背景及意义
锦纶（nylon），也称尼龙，在中国所有的聚酰胺类纤维都称为锦纶。由于锦纶的原料资源丰富，而且与纯尼龙相比锦纶的热性能、阻燃性、力学性能都明显优于纯尼龙，而且所需的制造成本与普通尼龙相差不多，所以在我们生活和工业生产中被广泛使用。
淮安锦纶化纤有限公司座落于淮安市涟水经济开发区，我院安排我们在此实习了四个月，它是金轮集团在淮安进行投资的一个重点项目投资额达到2.17亿元，占地面积达到500亩，年产达到20000吨，在淮安涟水经济开发区属于龙头企业。公司分为一厂和二厂，我们的毕业设计是根据一厂的生产情况进行分析和设计的。公司引进瑞士立达公司生产的先进的一步坊牵伸卷绕机、直捻机、宜昌直捻机和高速喷气织布机，建有国内先进100吨/日高粘切片聚合生产线、15套德国进口巴马格公司生产的四纺机、六头纺、一步纺牵伸卷绕机、60台Fa726/Fa727加捻机、40台K3501b宜昌直捻机、60台ASG600型高速喷气织布机、两条国内先进的JL-1800型浸胶机生产线及油锅炉、污水处理、空调冷冻、高低配电等公用功能。整体牵伸和加捻两个车间，实现提质、节能、节人的改造目标，经过一期改造和二期改造项目全部竣工投产后，将达到7万亩帘子布生产能力，可实现年产值20亿元，可实现利税超亿元目标。我们在淮安锦纶化纤有限公司实习了四个月，对于聚合工段有了比较透彻的了解，我们的论文正是来自于实践，是在淮安锦纶化纤厂的聚合工段取材而来的。
我国聚酰胺工程塑料的应用也会在未来被逐步推广，锦纶和聚酰胺工程塑料产量的增加必将带动锦纶6聚合装置的生产能力的增加。因此，锦纶6聚合装置的生产能力近年来将有较快的发展。为此，大容量锦纶聚合成产技术将成为我国化纤行业结构调整和技术改造的重点之一。
大型锦纶聚合装置的国产化和高度自动化对提高项目的经济效益具有极其重大的意义。在已有的国产化技术开发基础上，首先实现40-50t/d的装置，然后进一步实施对100-150t/d的技术的开发，不断提高我国的锦纶聚合生产技术水平[5]。
锦纶在生活中应用广泛，其独特的性能而在服装、工业和装饰三大领域占有重要的地位。随着人民生活水平的日益提高，锦纶的品种和数量均不断的被提出新的要求，而目前锦纶还有很大的发展空间，因此锦纶产品现还存在着极大的开发潜力。由于淮安锦纶化纤厂原系统采用的是继电逻辑控制，因此性能不稳定，维护困难而且产生人力资源的浪费。因此须对原设备进行改造。采用西门子SIMATIC S7-300和WinCC软件，开发了符合淮安锦纶化纤厂聚合生产工艺要求的PLC控制装置，选取了适合实际生产的各种传感器和阀门，设计了锦纶聚合控制系统的监控系统。通过充分利用PLC的优点，能很大程度上减少占地面积和设备故障率。
