Hs2000 Distribution System In The Lime Kiln Control

The vertical limekiln is the important equipment in many manufacture. In the charge mixture and seperating silicon and the carbonation decomposition process of the sinter alumina manufacture, limekiln is especially the key equipment. To the problem of limekiln automatic control, lots of people have a series of research and Approach in the late,most of them selected the PLC control system,or the auto control of the key device of the limekiln,but the hole system. In this article,we give a complete development and research for HS2000 control system to the limekiln,and successfully realize a DCS control.The hardwares of HS2000 control system has a higher redundant function.When the hardwares are abnormal,the system will auto diagnose it and give a non-disturbance conversion.It is a efficient and dependable control system by a series chooses of the HS2000 system hardwares and local control devices.In addition,with the editor program for control station and operator station(such as the complies of function block drawing, ladder block drawing, operator's interface and historical trend etc.),it comes true for all process parameter's realtime monitor and the trend in history.The hole Chinese interface and the cartoon picture, the realtime monitor and the alarms for abnormal status,they all provide the convenience for the production. It is very profitable to control and stabilize the limekiln production.The report founction in every day and every shift,that also provide the benefit for inquiry and management.The people will summarize experiences and adjust operation.For the limekiln process devices(such as charge mixture, feeding, distribution and limekiln discharging etc.),automatic control is completely achieved.In normal production,all process(feeding distribution and limekiln discharging etc.) require nothing manual control.It is a higher automatic system. In addition, the design and generating of this system have a useful help to relize auto control for other vertical blast furnace.It has a better effect in detecting and controll and operating and energy conservation.
