摘要
依据《大气氨源排放清单编制技术指南(试行)》所给废气脱硝氨排放因子,会严重低估脱硝氨排放量。脱硝过程中,未参与还原反应的氨气形成氨氮物,并通过固体颗粒物、脱硫废水等介质迁移外排,大部分最终以氨气形式排放至大气。使用未参与还原反应的氨气浓度代替"氨逃逸",能够更真实反映废气脱硝的氨排放水平。依据实际用氨量和理论用氨量之间的差值,可用于计算分行业的氨排放因子、烟气脱硝氨排放浓度。
According to the "Destruction Technical Guide for Atmospheric Ammonia Source Inventory(Trial)", the denitrification ammonia emission factor will seriously underestimate the amount of denitrifying ammonia emissions. In the denitration process, ammonia gas that is not involved in the reduction reaction forms ammonia nitrogen, and is discharged through a medium such as solid particulate matter and desulfurization wastewater, and most of them are finally discharged to the atmosphere as ammonia gas. By using the ammonia concentration that is not involved in the reduction reaction instead of the "ammonia escape", the ammonia emission level of the exhaust gas denitration can be more accurately reflected. According to the difference between the actual ammonia amount and the theoretical ammonia amount, it can be used to calculate the ammonia emission factor and the flue gas denitrification ammonia emission concentration in different industries.
