变频器在煤矿通风机节能监控系统中应用研究

Application of frequency converter in energy saving monitoring system of coal mine ventilator

通风机作为煤矿井下的主要设备,担负着为井下输送新鲜空气和排出浑浊空气、煤尘、粉尘、瓦斯等污染气体的主要任务。但同时矿用通风机也是矿用设备中主要耗能设备,因此以矿井通风监控系统为研究对象,结合当前矿井布置、通风要求以及耗能指标,对通风系统进行研究设计,分别对通风监控系统软、硬件部分进行详细设计,并将变频器应用到通风机的控制上。通过对实际应用效果的分析,表明该系统具有操作简单、可靠性高、降低能耗等优点,经济效益明显。

Ventilator as a major coal mine equipment,responsible for the underground transport of fresh air and discharge of turbid air,coal dust,dust,gas and other polluting gas main task,the mine ventilation is also the main energy-consuming equipment in mining equipment.the mine ventilation monitoring system was taken as the research object,combined with the current mine layout,ventilation requirements and energy consumption indicators,the ventilation system research and design,system hardware and software part were designed in detail,and the inverter was applied to the control of the fan.Through the analysis of the practical application results,the system has the advantages of simple operation,high reliability and low energy consumption,with obvious economic benefit.
