文档介绍：基于DCS的硫回收系统设计
摘要
20世纪70年代中期,大规模集成电路取得实破性的发展,8位微处理器普及,使自动化仪表工业发生巨大的变化,其中原来正处在十字路口的集中式计算机控制系统,很快吸收了微处理器技术,期间又经过几十年的发展最终诞生了DCS集散控制系统。本文在此介绍了dcs在各个历史阶段的发展历程,尤其是它在化工行业的应用和发展。此外本文主要讲述了I/A Series自动控制系统,文中详细介绍了I/A Series系统的特点、网络结构以及他的软件、硬件,以及应该怎样根据工艺设计系统。硫回收克劳斯硫回收发展已有一百多年的历史,到现在已是非常成熟的生产工艺,本文根据硫回收的工艺要求设计了claus硫回收系统,对整个系统的设计保证了硫回收的连续性、稳定性和高效性,在经济及社会效益方面均取得了良好效果。

ABSTRACT
   The 20th century 70's intermediate stages, the large scale integrated circuit obtains solid broken the development The position microprocessor is popular, causes the Process Automation Instrumentation industry to have the huge change, in which is occupying originally the intersection puter control system, has absorbed the microprocessor technology very quickly, the period passed through several dozens years development finally to be born the DCS collection and distribution control system This article introduced the dcs in the history in various stages of the development process, especially its application in the chemical industry and development. Moreover this article focuses on the I / A Series automation systems, the article detailed the I / A Series system features, network architecture, and his software, hardware, as well as how to design systems based on technology. Claus sulfur recovery sulfur recovery has been the development of more than one hundred years of history, and now has a very mature production technology, this article in accordance with the requirements of sulfur recovery technology designed claus sulfur recovery system, the design of the entire system to ensure the continuous recovery of sulfur , stability and efficiency in the economic and social benefits were achieved good results.
