摘要
介绍了紫外吸收光谱法烟气在线监测的原理和数据处理方法 ,分析了烟尘对不同光谱数据处理结果的影响及各方法的优缺点。利用紫外吸收光谱法不仅可以进行烟气排放的在线监测 ,同时能进行烟尘检测。与其他光谱法相比 ,差分吸收光谱法计算结果受烟尘的干扰最小 。
The principle and several methods of optical absorption spectroscopy analysis are introduced.The influence of soot was discussed briefly.Numerical simulation results of the above methods are presented.It is proposed that a single online emission monitoring system can monitor both of gases and soot.The comparison with different spectroscopic techniques shows that differential optical absorption spectroscopy is a good online monitoring technique.
