摘要
为提高甲烷气体浓度测量的精度和稳定度,避免煤矿瓦斯爆炸事故的发生,本文在空间双波长差分法的基础上,采用旋转滤光盘装置,实现了双波长时间差分检测法,从而避免了光源不稳定、背景光干扰以及探测器零漂的因素的干扰,有效的提高了测量精度。实验结果表明,该方法的最大相对误差和稳定度均满足工程应用要求,具有较好实用性和应用前景。
To improve the accuracy and stability of methane gas concentration measurement and avoid the occurrence of gas explosion accidents in coal mines,a dual wavelength differential time difference detection method is implemented based on the space dual wavelength difference method and a rotating filter disc device,which avoids the factors of the instability of the light source,the interference of the background light and the zero drift of the detector. The interference is effective to improve the measurement accuracy. The experimental results show that the maximum relative error and stability of the method meet the requirements of engineering application and have good practicability and application prospect.
