便携式烟气预处理器技术在比对监测中的应用

对2种便携式烟气预处理器在比对监测中的实际应用进行探讨,通过对2种烟气预处理器工作原理及在实际应用中的监测数据进行分析比较,显示在"高湿低硫"条件下,电子冷凝预处理器析出的冷凝液会造成二氧化硫的损失,在应用中应加快除水,减少烟气与冷凝水接触的时间,并防止冷凝液出现在伴热管线与预处理器烟气入口之间。而便携式Nafion预处理器由于具有独特的干燥性能,抗干扰能力,在"高湿低硫"的比对监测中具有较好的可比性和适用性。

Analysis of Portable Flue Gas Pre conditioning Technology and Its Application in Comparison Monitoring

Practical applications of two portable flue gas pre-conditioning instruments in comparison monitoring were discussed .By comparing the principles of the two instruments and data obtained from practical applications , it was found that under the condition of high humidity and ultra-low emission ,SO2 loss would occur as a result of condensation fluid from electronic cooler .It was suggested that water should be removed more quickly during application , and reduce the contact time period between the gas and the condensa-tion fluid.In addition, the condensation fluid should be prevented from present in between the thermos tube and the inlet of the pre -conditioning instrument .Portable Nafion pre-conditioning instrument has unique drying performance and capability of resisting interfer -ence, and it provides good compatibility and applicability in comparison monitoring test in high humidity and ultra -low emission.
