The Design And Application Study Of DCS Control System In The Roasting Technology For Zink Smelting

DCS control system is a kind of distributed computer control system ,Incorporating computer application technology , network communication and course control technology. Adopted in hydrometallurgy for zinc smelting , DCS control system can control and monitor the whole production technology, meanwhile, And implementate system trouble diagnose, maintain and control the function configuration systematically, So that we could get an antomation way to measure , reveal , control etc.Thus the automation of realizing smelting the craft course effectively controls.This paper takes the extended project item of the zinc smelting system 100,000 tons per year in Henan gold & lead as background to develop work research ., Through analysising the automatic current situation of zinc smelting and contrasting the characteristics of PLC , DCS , FCS control system, We select DCS control system for use and control the process Tech. in the zinc craft of roasting . In the course of designing , according to the zinc roasting technological requirement ,We confirm control the content of. DCS, We Have designed the hardware system, software system,etc. in the whole DCSsystem. On the basis of installing, debugging, the design of this project DCS system has been improved and supplemented again. Meanwhile , We carry on analysis and research to the operation conditions of this project. Successing of project can realize automation to detect of parameter for roast craft, reveal , control ,etc. The control system roasted in the craft is connected with other control systems and production scheduling systems through open Ethernet in the system, the senior executive of the factory can grasp the condition of production of every department in time, and carry on macro adjustments and controls, It may realize greatest economic benefits and social benefit that is produced.In chapter one of this text ,we have compared several kinds of control systems , and selected DCS control system to control the process Tech in zinc smelting system. These are on the basis of analyzing that zinc smelts automatic current situation of the developmenting. And we has introduced the development of DCS briefly and carried on the simple introduction to DCS.In second - three this text,, four chapter ,According to roast from zinc craft...
