[Abstract]:In view of the wide application of bag dust collector in industrial dust removal, this paper designs an optimized energy saving dedusting control instrument for bag dust remover. The purpose of this instrument is to increase the efficiency and effect of dust removal and prolong the service life of cloth bag. Reduce the energy consumption caused by the operation resistance of the precipitator, and achieve the control requirements of optimizing the dust removal. Firstly, this paper briefly explains the background significance of the research and the current research situation at home and abroad, studies the dust removal process of the bag dust collector, and designs the control system scheme, the hardware scheme and the software scheme of the dedusting control instrument. Secondly, the hardware platform and software program of the controller are designed, and the fuzzy intelligent control algorithm and the PID control algorithm are put forward. Among them, this controller hardware system is based on STM32F4 microcontroller as the core design, completed the sensor signal A / D conversion, frequency converter control, switch input and output, touch screen display, 485 communication circuit design; In the software design, the modular design is put forward, and the system initialization configuration, the function module configuration, the intelligent pulse injection control, the intelligent induced fan control and so on are programmed respectively for each functional module program. Finally, part of the controller is debugged and debugged in the laboratory. The debugging results show that the controller has strong anti-jamming ability, stable operation and safe and reliable operation. The control algorithm of induced draft fan is simulated by simulation software, and the simulation results show that the control effect is good. This controller has the following innovations: 1. The pulse injection control is realized by fuzzy algorithm. According to the expert system, the PID control of the induced draft fan is realized by optimizing the energy saving control of the induced fan; 3. The hardware structure is highly integrated, this controller integrates micro-controller, sensor, output control in one.
