基于大气环境的固定源细颗粒物测试方法研究进展

Progress on Testing Methods for Fine Particulate Matter for Stationary Sources based on Atmosphere

国内对固定源细颗粒物研究还较为薄弱,主要是缺乏合适的测试方法。由于基于大气环境的稀释测试法可在一定程度上模拟烟气排放至大气环境的物理化学过程,所以该法正成为研究固定源细颗粒物排放特征的重要手段。本文对国内外基于大气环境的固定源细颗粒物测试方法进行了系统介绍与分析,指出该测试系统应向小型化、便携式方向发展,以满足不同浓度、不同湿度、不同温度固定源细颗粒物的测试需要。

The study on fine particulate matter of stationary sources is relatively weak in China,the main reason is the lack of suitable testing methods. Dilution testing method based on atmosphere which can simulate the physical and chemical evolvement process of stack gas from stationary sources emit to the atmosphere,so the method has become an important means for studying the fine particulate matter emission characteristics of stationary sources. This paper introduces the testing methods of fine particulate matter for stationary sources,points out that the test system should be developed in the direction of miniaturization and portable in order to satisfy the testing needs of different concentration,different humidity and temperature of fine particulate matter for stationary sources.
