在化工生产的过程中,经常会接触到一些有毒有害气体,有些装置操作复杂,要求精度高,劳动强度大。DCS系统彻底改变了原始落后的生产状态,可以代替人的重复性劳动,摆脱繁重、脏乱、危险的环境,保障设备及人身安全,减轻劳动强度,改善劳动条件。DCS即集散控制系统,又称分布式控制系统(Distributed Control System) [3]。它的主要基础是4C技术,即: Computer(计算机)、Control(控制)、Communication(通信)、CRT(显示技术)。DCS系统通过某种通信网络将分布在工业现场附近的现场控制站和控制中心的操作员站及工程师站等连接起来,以完成对现场生产设备的分散控制和集中操作管理[4]。
Application of DCS in the coke-oven gas dehydration
Abstract
The DCS system used for industry control is designed , in order to achieve the automatic control of the coke-oven gas dehydration . In this paper , the technonomy survey and system configuration are introduced . The realization of the coke-oven gas dehydration which used the method of sequence time are described in detail. The system is simple and convenient to adjust the parameters,and is fully automatic control. Its security and efficiency are improved greatly.
