针对工矿企业的除尘系统,提出了一种脉冲式除尘设备控制方法,将脉冲阀作为被控对象,并可任选同时工作的阀门,脉冲阀的工作时序为启动延时后,阀门按通电、断电时序反复进行,直到扩展时间到或停止信号到来,每个环节时间可调。基于单片机,研制了除尘设备控制装置。现场运行表明,该方法易于实现,其控制装置具有体积小、低功耗、可靠性高等优点。
Aiming at the dust removal system of industrial and mining enterprises, a pulse dust removal equipment control method is proposed. The pulse valve is taken as the controlled object and the valve which can be operated at the same time is optional. The working sequence of the pulse valve is the starting delay, The power-off sequence is repeated until the expansion time arrives or stops, and the timing of each link is adjustable. Based on the single chip microcomputer, a dust removal equipment control device was developed. Field operation shows that the method is easy to implement and the control device has the advantages of small size, low power consumption and high reliability.
