| 摘 要： | 针对目前已安装的烟气在线监测系统的组成、安装、故障处理及运行维护等问题进行简略性阐述。烟气污染物在线监测系统是实时、连续监测污染物参数的系统,主要监测烟气中的颗粒物浓度(或浊度)、气态污染物浓度(SO2、NOx、)、辅助参数(烟气温度、流速、氧量、湿度、压力)等【1】。颗粒物浓度监测方法有激光透射法、激光反散射法及电荷感应法,气态污染物浓度监测方法主要有完全抽取法、稀释法、电化学法3种。在电力行业中,颗粒物监测主要采用激光反散射法,气态污染物浓度监测主要采用完全抽取法。

| Abstract: | For currently installed flue gas online monitoring system components, installation, troubleshooting, operation and maintenance of such issues briefly described. The online monitoring system of flue gas pollutants is a real-time, continuous monitoring of pollutant parameters, main monitoring in the flue gas particulate concentration （or turbidity）, gaseous pollutants （SO2, NOx）, the auxiliary parameter （flue gas temperature, flow rate, oxygen content, humidity, pressure）and so on. Particulate concentration monitoring methods are laser transmission method, laser inverse scattering method and charge induction method, gaseous pollutant concentration monitoring methods include completely extraction method, dilution method, electrochemical method three kinds. In the electric power industry, particulate monitoring mainly uses laser inverse scattering method, monitoring the concentration of gaseous pollutants mainly uses the complete extraction method. |
