湖北省主要固定燃烧源大气颗粒物及VOCs排放特征研究
Emission Characteristics of Atmospheric Particles and VOCs of Mainly Stationary Combustion Sources in Hubei Province
摘要
Abstract
This paper conducts monitoring research on the typical atmospheric particulate matter and volatile organic compounds (VOCs)in stationary combustion sources from 21 typical enterprises in nine cities of Hubei province from January 2014 to December.The paper investigates the emission characteristics and composition of the atmos-pheric particulate matter and VOCs.The results show that the particulate matter emissions and capacity are posi-tively correlated.The smaller the particle size is,the lower the mass percentage of the total particulate matter is. The mass concentration of PM10 and PM2.5 in exhaust gases from different fuel boilers are petroleum coke coal>coal>living garbage.But there is only PM1.0 detected in the gas boiler exhaust gases.In the exhaust gases of coking plant and steel plant boilers,alkenynes dominates the VOCs,accounting for 79.21%and 81.09%respectively,and the percentage of ethylene of the total VOCs is the highest,being 69.13%and 68.88%respectively.In the exhaust gases of fuel boiler,alkenynes dominates the VOCs,accounting for 91.74%.In the exhaust gases of gas boiler, VOCs mainly include olefin hydrocarbon (acetylene)(37.96%)and aldehyde resin (38.79%).The components and concentrations of VOCs are affected by different types of boilers and fuels.The concentration levels of VOCs in the exhaust emissions are shown as:coking plant>iron works,boiler fuel boiler>gas boiler,and the components are more complex.关键词
