【摘要】：本文针对用定电位电解法测定钢铁企业烧结机机头烟气中一氧化碳对二氧化硫的干扰进行研究。针对二氧化硫的监测方法,选取了非分散红外法和定电位电解法进行比对。采用一氧化碳标准气体实验,不同浓度的一氧化碳标准气体对二氧化硫测试仪的显示值贡献,得出线性回归方程,建立数学模型,采取分段式的数学模型,对一氧化碳浓度值进行二氧化硫测试仪修正,最后实地现场对钢铁烧结机头烟气进行监测,得出二氧化硫数据和非分散红外法测出二氧化硫数据进行比对。实际实验表明,崂应3012型测试仪修正后的数据和崂应3026型红外分析仪测定数据得出相对误差结果范围在-10.71%~8.14%,误差在15%内,数据之间基本无显著性差异。德图350型分析仪崂应3026型红外分析仪测定数据得出相对误差结果范围在-8.24%~9.88%,误差在15%内,数据之间基本无显著性差异。3012型测试仪和350型分析仪俩者实际测得的数据得出相对误差结果范围在-5.56%~4.76%,误差在15%内,数据之间基本无显著性差异。3012型测试仪和350型分析仪俩者修正后的数据得出相对误差结果范围在-12.36%~10.26%,误差在15%内,数据之间基本无显著性差异。在实际监测高浓度一氧化碳过程中,应对实际监测数据后进行人工修正,或在定电位电解法仪器中对系统内软件程序进行升级,也可使用非分散红外法仪器。
[Abstract]:In this paper, the interference of carbon monoxide to sulfur dioxide in the flue gas of sintering machine head of iron and steel enterprise is studied by means of constant potential electrolysis. According to the monitoring method of sulfur dioxide, the non-dispersive infrared method and fixed-potential electrolysis method were selected to compare them. In the experiment of carbon monoxide standard gas, the contribution of different concentration of carbon monoxide standard gas to the display value of sulfur dioxide tester is obtained, the linear regression equation is obtained, the mathematical model is established, and the segmental mathematical model is adopted. The carbon monoxide concentration is modified by sulfur dioxide tester. Finally, the flue gas of iron and steel sintering machine is monitored on the spot, and the sulfur dioxide data are compared with those measured by non-dispersive infrared method. The actual experiment shows that the corrected data of Lao Ying 3012 tester and the data measured by Lao Ying 3026 infrared analyzer show that the relative error range is -10.71 1 / 8.14, the error is within 15%, and there is no significant difference between the data. Detu-350 Analyzer Lao Lao should measure the data of Model 3026 Infrared Analyzer. The result of relative error is -8.24 and 9.88, and the error is within 15%. There is basically no significant difference between the data. The actual data measured by the type 3012 tester and the 350 type analyzer show that the relative error results range from -5.56 to 4.76, and the error is within 15%. There was no significant difference between the data. The revised data obtained from the data obtained by the model 3012 tester and the 350 type analyzer showed that the range of relative error was -12.36 and 10.26, the error was within 15%, and there was no significant difference between the data. In the process of actual monitoring of high concentration carbon monoxide, manual correction should be carried out after actual monitoring data, or the software program in the system should be upgraded in the fixed potential electrolysis instrument, and the non-dispersive infrared instrument should also be used.
