Application Research On Cement Clinker Production Congtrol Methods With Waste Heat Power Generation

Cement clinker calcination is one of the main components of cement process, in cementclinker burning process, enterprises need to consume a large amount of coal, raw materialsand other natural resources, and produce large quantities of heat and SO2, CO gas. In order toadapt to China’s economic transformation and realistic national conditions and requirements,the effective use of cement clinker calcining residual heat, to achieve energy-saving emissionreduction results, cement enterprises in new dry process cement production line to increase awaste heat power generation technology, the technology is the use of cement kiln kiln tailexhaust waste heat for power generation technology. Cement clinker production and wasteheat generating coordinated control has become one of the important research topics ofcement control.In the cement clinker production line into waste heat power generation, cement clinkerproduction and waste heat power generation interaction, mutual influence between them, inview of process index and energy consumption in relation to each other, research coordinationoptimization setting control scheme, initially established a new dry cement clinker productionand waste heat generating coordinated control model, coordinated control is aimed atstabilizing cement clinker quality and output at the same time, make full use of waste heatpower generation, reduce the consumption of cement clinker production, consumption,thereby reducing the cement production per unit area yield cost, raise business economicbenefits.A detailed analysis of this topic in cement clinker production and waste heat powergeneration of mutual influence, interaction on the basis, through the comparison of the PIDcontrol, fuzzy control and fuzzy PID control, the fuzzy PID compound control with fuzzycontrol and PID control dual advantages of conclusion. After the MATLAB simulation, and itwas obvious that Fuzzy-PID control than the PID control has better dynamic characteristicsthan the fuzzy control and it has high precision in steady state. By using the simulation results,the selection of the fuzzy-PID control as the kiln head and coordinated control of AQCcontroller. The fuzzy-PID control study, focuses on the design idea and steps of fuzzycontrol. Design scheme of waste heat power generation and cement clinker production systemcoordinated control. Select two wind temperature and pressure as control parameter,realization of grate cooler in temperature in a gas valve control; high temperature rotatingspeed of the fan and C1temperature and other parameters, to achieve in SP furnace flue gasvalve control.Then, using MATLAB simulation, verifies the effectiveness of the algorithm. Andthrough the MATLAB simulation, test of grate cooler in temperature in a gas valve valvecontrol module design and C1outlet exhaust valve opening control module design, on thebasis of this, the fuzzy PID controller to join CBF, the off-line test before and after addingcoordination controller, two temperature air temperature changes and through the analysis ofvalve regulated in recorded history, comparison of manual control and coordinated control ofvalve opening.Finally, this paper introduces the DCS system, OPC interface, human-computer interface and software design, using VB and MATLAB language part of the control program and theman-machine interface, through the OPC interface to the set, to achieve DCS connected withthe database, and then through the database to achieve coordinated control calculation methodinvocation.
