烧结烟气SO2监测干扰因素分析及改进

Analysis of Disturbance Factor of Sinter Flue Gas Sulfur Dioxide Monitoring and Improvement

某钢铁集团公司在实施烧结脱硫工程后，脱硫出口烟气连续监测数据与日常手工比对监测数据相比超过国家规定。为此通过定电位电解法、非分散红外吸收法和紫外差分吸收光谱法同时进行了比对监测，人为调整了运行工况，并使用一氧化碳气体标定监测设备分析了干扰因素，提出了改进建议。

After implemented sinter desulfurization in an iron and steel group shows that the constant flue gas monitoring data of the desulfurization outlet violate nati compared with daily manual monitoring data. For this, tential electrolysis method, non-dispersive infrared tion spectroscopy together corporation, it onal regulation compare the monitoring data by using fixed poabsorption method, and differential optical absorp- Adjust the running condition. And analyze the disturbance factor via carbon monoxide gas calibration equipment. Propose improving suggestion.
