Paper Abstract

Fourier transform infrared spectrometry can be used for harmful gases online detection, Due to the overlap and mutual interference between the absorption spectra, accurate detection is very difficult for the mixture gas. In the wave number of 400~2200 cm-1, the infrared absorption spectrum characteristics of typical harmful gases in underground closed environment were analyzed, the position of characteristic absorption peak was studied, and the infrared absorption frequency of each harmful gas was determined. The reasonable detection scheme was designed, and the mutual interference of the detection was eliminated. The harmful gases include SO2, CO2, H2S, NH3, NO2, CO, O3, H2CO, C6H6 and H2O.
