摘要在监测超低排放烟气低浓度颗粒物时，采用玻璃纤维滤筒作为较高温度烟气环境下的颗粒物收集器时，存在颗粒物含量监测结果不准确的情况。通过选取同一批次滤筒进行平行试验，进行不同温度和冷却条件的处理，分析了玻璃纤维滤筒的失重情况及影响滤筒恒重的原因。结果显示，烘干时间、烘干温度、存放环境等均对滤筒恒重存在影响，据此提出了滤筒使用的前处理方法。

Abstract: When using glass fiber filter cartridge as relatively high-temperature particulate matter collection material in ultra-low emission flue gas monitoring, the detection results of particulate matter concentration may be inaccurate or negative. Selecting the same batch of filter cartridges for parallel experiments, the weight loss of glass fiber filter cartridges under different temperatures and cooling conditions were studied and the reasons for influencing the constant weight of filter cartridges were analyzed. The results showed that drying time, drying temperature and storage environment may influence the constant weight of filter cartridges. Based on the above, the feasible pretreatment method of filter cartridges was proposed.

Key words: particulate matter monitoring glass fiber filter cartridge constant weight high-temperature gas
