Control And Research On Cyclone Pre-heater

The process of the cyclone pre-heater is the core part of the cement produce, which belongs to the complex heart reaction process. The effect of pre-heater to raw will impact on the quality of cement, energy consumption and environmental protection. At present, the cyclone pre-heater's closed loop uses tradition PID control strategy in the nation. There are many defects in it, such as it is so difficult to ascertain the parameter of system that can not reach to the ideal effect, big errors, low demonstration precision, too simple controlled algorithm and so on. This paper use two class DCS control system to improve control strategy, which can realize the control of the process of the cyclone pre-heater and supercise the request parameter. The cyclone pre-heater not only ensure both the stabilization of produce and equipment's safety, but also make the process of produce and equipment's safety, but also make the process of produce to the best point, which can reach to aim of high quality, high efficiency, low consumption.According to the technical request of cyclone pre-heater, this paper presents a control strategy. I choose the chip of S3C44B0X which is produced by Samsung corporation, the master control platform according to the reality needs function to extent out circuit. According to the reality need of system, I should collect three signs: the temperature, the intensity of pressure, rate of flow. I chosen the corresponding sensor, proper motion has designed that the signal realizes the detecting to the signal and circuital controlling of hardware coming the circuit nursing board and the two-way silicon controlled hardware .Realize the corresponding function during the past bottom drive such as besides, having adopt ADC and PWM to be the software platform at present in the world come very popular muClinux OS, having compiled and composed by self. The gas temperature has improved the tradition PID control mode to whirlwind pre-heater outlet, has introduced under the control of tactics ameliorating, has been in progress mixing up method of integration of PID with classics PID control algolithm, has gained development speed of response quickly, has surpassed a tune measuring the fine effect that the temperature under the control of stabilizes for a short time. Have realized data supervisory control, the artwork display as a whole in system, the buzzer phone that the mouth gets along to handicraft and the electricity malfunction by I/O carries out real time warning function.
