烟气在线监测系统及思考

固定污染源排放的烟气会对环境造成污染,对其进行科学监测至关重要。本文介绍了现有的烟气在线监测系统,包括空气质量自动监测系统、烟气排放连续监测系统、差分光学吸收光谱法在线连续监测系统、物联网下无线传感器网络技术在线监测系统等,介绍了每个系统的组成、技术特点、监测方法、实际应用和发展方向,并从量值溯源和远程校准两个方面对烟气在线监测系统与计量系统的关系进行了阐述。

Present Situation and Thoughts of On-line Flue Gas Monitoring Systerms

The flue gas emitted from stationary pollution sources has greatly increased pollution to the environment , and it is very important to scientifically monitor the flue gas. In the paper, the authors introduce the status of the on-line flue gas monitoring systems, including automaticair quality monitoring system (AQMS), continuous emission monitoring system (CEMS) based on differential optical absorption spectroscopy(DOAS), on-line wireless sensor network monitoring system under the internet of thing .The structure of every on-line flue gas monitoring system, technical specification, practical applications and development direction have been described. And the relationship between the on-line gas monitoring systems and meteorological systems is discussed in this paper.
