【摘要】：煤矿主通风机是煤矿井下的“呼吸系统”,担负着向井下输送新鲜空气,排出瓦斯、煤尘和污浊气流的主要任务。同时,风机也是煤矿耗能最多的设备之一。因此矿用主通风变频监控系统的应用研究对于提高设备的自动化管理水平,保障通风机安全、可靠、经济地运行具有及其重要的意义。本文以某矿业集团公司二号煤矿矿井通风系统为研究对象,根据高压电机变频节能控制原理,经过现场调研、通风阻力测定分析,根据技术性、经济性、安全性、易操作性,结合矿山企业主井通风控制系统的现状和以后的生产需求,制定了以美国洛克韦尔公司的1769系列PLC为控制核心,北京力控组态作为上位机监控软件的变频节能控制(工频备用)方案,同时进行了设计方案的可行性和节能效果的论证。最后,对该矿主通风机变频节能监控系统进行系统设计与工程实施、调试。工程实践表明,本次设计的黄陵二矿主通风机变频节能监控系统技术先进、安全可靠、操作简单的特点,保证了煤矿井下通风系统安全。系统运行至今累计节电800多万度,仅电费一项为企业增收400多万,经济效益明显。
[Abstract]:The main ventilator of coal mine is the "respiratory system" of underground coal mine, which is responsible for the main task of conveying fresh air, discharging gas, coal dust and dirty airflow to the underground. At the same time, the fan is also one of the most energy-consuming equipment in coal mines. Therefore, the application research of frequency conversion monitoring system for mine main ventilation is of great significance to improve the automatic management level of equipment and ensure the safety, reliability and economical operation of ventilator. This paper takes the ventilation system of No. 2 coal mine of a mining group company as the research object, according to the principle of high-voltage motor frequency conversion energy-saving control, through field investigation, ventilation resistance measurement and analysis, according to technical, economic, safety, easy to operate, Combined with the present situation of mine main well ventilation control system and the future production demand, the 1769 series PLC of Rockwell Company of the United States was adopted as the control core. The Beijing force control configuration is used as the frequency conversion and energy saving control (power frequency reserve) scheme of the upper computer monitoring software. At the same time, the feasibility of the design scheme and the energy saving effect are demonstrated. Finally, the system design, engineering implementation and debugging of the main mine fan frequency conversion and energy saving monitoring system are carried out. The engineering practice shows that the frequency conversion and energy saving monitoring system of the main ventilator in Huangling No. 2 Mine is advanced in technology, safe and reliable, and simple in operation, which ensures the safety of underground ventilation system in coal mine. Up to now, the system has saved more than 8 million degrees of electricity, and the electricity cost alone has increased by more than 4 million for the enterprise, and the economic benefits are obvious.
