Application of intelligent frequency conversion technology in mine ventilation system

本文围绕智能变频技术在矿井通风系统的应用进行研究,介绍智能变频局部通风系统的组成,阐述该系统的工作流程及其特征,就其根据矿井瓦斯浓度的变化自动变频的过程进行相关的试验研究,并进行理论分析,最后得出当矿井巷道中瓦斯浓度变化时,该通风系统能够根据其变化量自动调节通风机运转的频率,进而调整通风量,将瓦斯浓度控制在合理的范围内,保持井下适宜的工作环境。

This article mainly focus on the research of the intelligent frequency technique. First of all,it describes the form of the intelligent frequency conversion local ventilation system,then describes it＇s working mechanism and the feature. After that,begins the part of research on the process of automatic frequency conversion according to the change of mine gas concentration,finally make a conclusion that when the gas concentration changes in the mine roadway,the ventilation system can automatically adjust the fan＇s operating frequency,to adjust the ventilation and regulate the gas concentration in a reasonable range,in order to maintain the mine a suitable working environment.
