摘要

针对发电厂的稻草碎料备料工段,通过筛分法测定了物料颗粒的粒径和分布,同时测定了作业场所空气中PM10的浓度,及其中PM2.5所占的比例。结果显示:作业场所空气中的PM10浓度远高于国家标准的规定值,且其中PM2.5所占的比例达0.01%。建议在作业场所设置合理的除尘装置。

Abstract

Workshop air pollution is one of the most visible environmental problems in China.Inhalable particulates,in particular,have recently drawn more attention due to the pronounced influence on air quality and human health.In this study,the concentration and distribution of total suspended particulates（TSP）were investigated during the straw crushing process.The result showed that the concentration of inhalable particulates,with diameter less than 10 μm（PM10）,was much higher than the requirement specified by the national standards,and the proportion of particulates with diameter less than 2.5 μm（PM2.5） reached 0.01%.
