The Research Of The Control System Of Converter Gas Station

Converter gas in iron and steel enterprises is a major source of supply,steel is to provide enough fuel for steel,cast iron is very crisp,let pig iron to harden the need for steel,steel can be to remove iron impurities.At the same time can produce a large amount of CO.In steelmaking converter gas is waste gas,there is no gas purification,there are a lot of impurity,can become fuel after purification.However converter gas is discontinuous in the generation process,the pressure of gas transmission pipeline is not constant,thus cannot be directly used for secondary use,in order to ensure the converter gas can be used again,the most important problem is how to converter gas constant pressure stable transported to other users,to ensure the effectiveness and rationality of use.For converter gas recovery now both at home and abroad,there has been a lot of methods for solving the converter gas as fuel can be recycled,it can be stored in the gas through a pipe rack after dust,from the output of gas in the gas cabinet can be according to the requirement of the process of human controlling the output and the velocity,pressure control of the pipe.This article will introduce in detail the converter gas station output constant pressure control system,namely the actual process project.The control system is mainly combined with Henan krater technology company for Shanxi Rakhine industry &trade co.,LTD.,eighty thousand to carry on the design of the converter gas tank recovery project,introduced the control system as the main content of the main part,this paper expounds the function and effect of the main equipment,describes the alarm parameters of gas station,and the corresponding program flow,detailed instructions for the constant pressure control mode,the user can use constant pressure gas.Describes the actual operation situation,after the production and collect the image monitoring information and data,gas station of the whole system can be stable operation.This system has a good economic and social benefits.This article mainly USES the PLC-300 Step 7 simulators in offline programming software and PLCSIM debugging,use Win CC configuration software configuration screen time monitoring program running process,and at the scene debugging good sensitivity to each link of the work,the final PID controller can achieve at a rapid speed regulation electric valve,the purpose of real-time using encoder to determine accurately the gas in the gas piston moving inside ark,monitoring and improve the safety of the gas station,as to achieve the design standard of pressure constant.
