水分对“冷干法”废气污染源自动监控二氧化硫数据的影响分析

目前辽宁省重点排污单位大多采用"冷干法"污染源自动监测设备,该法要求进入分析仪的烟气为干燥洁净的,但一些设备由于老旧、损坏等原因导致干燥效果较差,二氧化硫数值较实际数值偏低。针对问题进行分析,并结合实际经验,对检查方法进行总结。

At present,Liaoning province key sewage units mostly used automatic monitoring equipment of cold dry flue gas pollution source,the law requires for entering the analyzer are dry and clean,however,due to old or damage and other reasons,some equipment have poor drying effect,and the sulfur dioxide value is lower than the actual value.Based on these problems,combined with practical experience,the examination methods were summarized.
