[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.
