| 摘 要： | 本文将差分光学吸收光谱(Differential Optical Absorption Spectroscopy,DOAS)技术中的浓度反演方法运用到烟气SO2监测中.利用SO2分子在300nm附近具有强吸收的特性,测量出烟气SO2的吸收光谱,用DOAS方法反演出SO2分子的浓度,消除了烟气中烟尘、水汽和其它成分的影响,使在线实时测量成为可能,在实验室内对几种SO2分子浓度样气进行了测量和浓度反演.

| Abstract: | Algorithms of concentration retrieved from atmospheric absorption spectra of DOAS technique are applied to monitor sulfur dioxide in flue gas in this paper.Because of SO 2 molecules strong absorption around wavelength 300nm,the absorption spectra were measured,from which the concentration of SO 2 molecules are evaluated by using algorithms of DOAS.This analysis procedure make an in site,real time measurement to be possible without the influences of gas dust,water vapor and other molecules in the flue gas.Several concentration SO 2 samples were measured and evaluated in laboratory. |
