脱硫洗涤塔废气中颗粒物监测方法研究OA

With the increasingly refined technology for ultra-low emission control of particulate matter from stationary pollution sources,the application of the filter cartridge method GB/T 16157-1996 has certain limitations under specific operating conditions(high water content and low temperature).This article primarily addresses the challenges in the application of particulate matter monitoring methods under specific operating conditions,and conducts a comparative analysis of the filter membrane method HJ 836-2017 and the filter cartridge method in terms of sampling time,sampling medium,quality control,and other aspects.The results of the comparative analysis indicate that the cartridge is easy to break due to excessive humidity and has problems such as excessive crystalline loading,while the filter membrane has excellent performance.This study not only proves the limitations of the cartridge method in monitoring particulate matter from stationary sources under high humidity conditions,but also provides a reference for the selection of cartridge and membrane methods under actual situation.
