基于数字化分析技术的烟气监测装置位置优化

Location optimization of flue gas monitoring device based on digital analysis technology

为有效解决原烟气监测装置烟尘堵塞监测探头、探头磨损严重导致传感器失效等现状,采用数字化分析技术对烟气监测装置位置进行了优化,最终位置确定为以两支管中心点为原点,Z=-4.75 m,X=-9 m处,并对重新选址后检测装置的工况参数进行检验。检验结果表明,探头重新选址后,装置平均仪表系数为12.744 21,变形度为0.43%,差压为220.395 4 Pa,装置精度达到了0.5级,满足设计规定。

In order to effectively solve the current situation that the smoke and dust of the original flue gas monitoring device blocks the monitoring probe and the sensor fails due to serious wear of the probe, the digital analysis technology is used to optimize the position of the flue gas monitoring device. The final position is determined at the center point of the two branch pipes as the origin, Z=-4.75 m, X=-9 m, and the working condition parameters of the detection device after relocation are tested. The test results show that after the probe is relocated, the average instrument coefficient of the device is 12.744 21, the deformation is 0.43%, the differential pressure is 220.395 4 Pa, and the accuracy of the device reaches level 0.5, which meets the design requirements.
