| 摘 要： | 以电化学传感器为核心的便携式烟气监测系统在使用中易受其他气体的干扰,造成监测结果误差较大;本文将反射式光纤传感技术、紫外吸收光谱方法、光纤光谱仪和计算机数据处理技术相结合,设计出能检测SO2气体的便携式烟气检测系统,经分析光电探测器的暗电流限制最低检测限,SO2检测限分别为2 mg/m3.

| Abstract: | The portable emission monitoring system used electrochemical sensors is Affected by other gases,which brings about serious errors;In this paper,We utilize the reflective fiber optic sensor,the UV absorption spectrum,the micro-fiber spectrometer and the computer data processing technology to design the emission monitoring system which can portably,real-time monitor SO2;Theoretical and experimental results prove that the dark current of CCD photodetector limits the lowest detectable limit,the lowest detectable limit of SO2 by this system is 2 mg/m3. |
