便携式傅里叶红外分析仪在垃圾焚烧行业固定源气态污染物监测中的应用

Application of Portable Fourier Infrared Analyzer on Monitoring of Gaseous Pollutant from Stationary Source in Waste Incineration Industry

随着国家对生态环境保护工作的重视程度不断加强,企业在深入治理后排放出的废气呈现出污染物浓度低、温度低、湿度高的特点,现有的监测方法已经在实际中渐现不足。基于三家典型焚烧企业固定源烟气特点,采用傅里叶红外法(FTIR)对烟气中的SO_(2)、NO_(x)、HCl、NH_(3)进行监测分析,并与传统吸收液法、电化学法及在线监测结果进行比较,实践证明FTIR法结果稳定性较好,与标准方法精密度基本一致,是一种测试污染源气态污染物简便快捷的准确方法。

Waste gas has the features after in-depth treatment by enterprise that low pollutant concentration,low temperature and high humidity,the existing monitoring method is not enough for use along with the state pay more attention to ecological environment protection work.Fourier transform infared spectromotry(FTIR)was used in monitoring analysis of SO_(2),NO_(x),HCl,NH_(3) of gas based on features of gas from stationary sources of three typical incineration enterprises,and the results were compared to results by traditional absorption solution method,electrochemistry method and on-line monitoring,the practice proves that FTIR has better stability,its results basically in line with the standard method precision,it is a easy,fast and accurate test method for gaseous pollutant.
