摘　　要：我国砖瓦工业量大、面广,生产技术相对落后,氮氧化物排放总量相对较高。针对砖瓦工业的窑炉特性、工艺特点和氮氧化物的生成机理,本文结合隧道窑的工作原理,对氮氧化物净化技进行系统性理论阐述和应用介绍,包括源头治理、过程工艺控制、低氮燃烧技术、选择性非催化还原技术(SNCR)、选择性催化还原技术(SCR)和臭氧氧化脱硝技术,企业可结合工艺特点、运行情况和技术经济性,选择适应于自身特点的氮氧化物处理技术。Chinaese brick and tile industry has a large volume and a wide range of areas,the production technology is relatively backward,and the total amount of nitrogen oxide emissions is relatively high.According to the kiln characteristics,process characteristics and formation mechanism of nitrogen oxides in brick and tile industry,combined with the working principle of tunnel kiln,this paper the purification technology of nitrogen oxides was systematically expounded and introducd,including source treatment,process control,low nitrogen combustion technology,selective non-catalytic reduction technology(SNCR),selective catalytic reduction technology(SCR)and ozonation denitrification technology.According to the process characteristics,operation and technical economy,the enterprise can choose the nitrogen oxide treatment technology which was suitable for its own characteristics.
