【摘要】：粘胶纤维是一种可再生资源,它不但弥补了天然纤维产量不足的缺陷,而且在质量的某些方面优于合成纤维,被广泛应用于生活,工业领域。随着人类对纤维制品的性能要求逐渐提高,产品的质量高低影响着企业的发展与效益。以引进奥地利LENZING公司的一种对粘胶纤维预烘干技术为基础,结合本公司生产实际操作要求加以技术改造,替代了原湿开松工艺处理,弥补了原工艺对粘胶纤维开松效果差,布丝不均匀的缺点,同时有利于纤维产品的稳定回潮,避免了设备漏毛的浪费现象。通过对粘胶纤维生产湿开松工艺流程简介,阐述了工艺生产中存在的问题,对控制系统的整体方案进行分析与选择,结合对人身安全与现场设备保护的需求,提出系统控制要求与方案,完成对湿毛风送电气仪表控制系统的设计,其中包括声光报警系统,安全联锁系统,电机控制系统。采用SIEMENS公司S7-400集散控制系统,完成对DCS控制系统硬件与软件的设计,包括硬件的选型与组态、控制联锁程序、上位机监控,能够满足对过程生产的控制需求。湿毛风送的主要设备均采用变频控制技术,不仅降低了能源消耗,还实现了平滑的调速控制,同时普遍应用电气与软件的连锁控制,生产得到了稳定的运行。
[Abstract]:Viscose fiber is a kind of renewable resource. It not only makes up for the shortage of natural fiber production, but also is better than synthetic fiber in some aspects of quality. It is widely used in life and industry. With the improvement of the performance requirements of fiber products, the quality of the products affects the development and benefit of enterprises. Based on a pre-drying technology of viscose fiber introduced from LENZING Company of Austria and combined with the practical operation requirements of the company, the technology was reformed to replace the original wet opening and loosening process, which made up for the poor opening effect of the original technology on viscose fiber. The inhomogeneity of cloth is also beneficial to the steady return of fiber products and the waste of equipment leakage. Based on the brief introduction of the wet opening and loosening process of viscose fiber production, the problems existing in the process production are expounded, the overall scheme of the control system is analyzed and selected, and the requirements of personal safety and field equipment protection are combined. The control requirements and schemes of the system are put forward, and the design of the control system of the wet hair air transmission electrical instrument is completed, including the acousto-optic alarm system, the safety interlocking system and the motor control system. The hardware and software of DCS control system are designed by using S7-400 distributed control system of SIEMENS company, including hardware selection and configuration, control interlocking program, upper computer monitoring, which can meet the control requirements of process production. The main equipment used in wet hair air transmission is frequency conversion control technology, which not only reduces the energy consumption, but also realizes the smooth speed regulation control. At the same time, the interlocking control of electric and software is widely used, and the production has been running stably.
