Research On The Control System Of Converter Gas Recovery Based On CS3000DCS

With the development of world economy and attention to environmental protection, Nowadays, converter coal gas recovery system has been an important part of the iron and steel enterprise. In the past, converter coal gas recovery system uses mostly the way of the field monitoring and manual control, lead to the Cast furnace phenomenon happened frequently, equipment failure rate is still high, and the production quality of the mixed gas is far from the energy requirements of the subsequent users, there is an urgent need for taking a practical and effective control method, establishing a fully functional control system so as to raise the utilization of the coal gas recycling, reduce the equipment failure and at the same time make the quality of the mixed gas reached the satisfactory criterion of the customersIn this paper, mainly changes the primal system of the80thousands reclaiming gas at converter in Ansteel. choose the Yokogawa CS3000DCS that fully stable performance and functional maturation.First, the selection of the site controller configuration (FCS) signal acquisition from field instrumentation, select engineer station (ENG) and man-machine operator station (HIS) as a man-machine interface program preparation and monitoring of field devices to control the platform. Secondly, the use of real-time control system redundancy within the network VNET network connection system all FCS, ICS and ACG other hardware devices, using Ethernet data transmission between ENG and HIS. Again, according to the site requirements of the production process, the configuration of various functional software engineer station (ENG) on the use of converter gas recovery cabinet control system flow chart drawn YOKGAWA CENTUM system view. Finally, such as off-line simulation and online ways to test various functions of the system, the system can guarantee the converter gas recovery, gas oxygen content of the test, ESP purification, compression machine compression, output to the user, such as every process smooth, real-time data acquisition and display field instruments, according to police records and real-time, historical curve interlock setting start and stop control devices and the valve opening, and generate important parameters.Compared with the former system, CS3000DCS have the traits that merits of easy operation, works normally, safe and reliable equipment, anti-interference capacity, simple programming directly, high control precision, in actual use reached the expected effect.
