摘要:
利用湿度发生器与SO2标准气生成湿度梯度测试气,比较“微压”式、半导体冷凝、Nafion管干燥3种便携式烟气预处理装置中的SO2损失率;结合各预处理装置的工作原理及特点,分析其除水效率下降的主要原因。通过现场比对测试,验证“微压”式和半导体冷凝烟气预处理装置的除水能力。为降低烟气湿度对测试结果的影响,提高监测数据的准确性提供参考。

Abstract:
In order to observe the water removal efficiency of portable dry flue gas pretreatment device, the humidity generator and SO2 standard gas were used to generate humidity gradient test gas, and the SO2 loss rates of “micro pressure” type, semiconductor condensation and Nafion tube drying were compared. Combined with the working principle and characteristics of each pretreatment device, the main reasons for the decline of water removal efficiency were analyzed. Through the field comparison test, the water removal efficiency of the “micro pressure” type and semiconductor condensation type flue gas pretreatment device was verified, which provides a reference for reducing the impact of flue gas humidity on the test results and improving the accuracy of monitoring data.
