摘要山东省实施DB37 2373-2018标准关于氮氧化物排放浓度限值100mg/m3后，我公司脱硝系统控制效果难以满足其要求。通过对我公司1、2号生产线原有脱硝系统采取更换、重新定位喷枪以及降低氧含量等密封堵漏和脱硝技改措施后，NOX排放浓度和排放量大幅降低，达到了NOX浓度排放新标准要求，同时也节约了生产成本，仅排污费一项，年可节省40万元以上。

Abstract: After the implementation of DB37 2373-2018 standard on the NOx emission concentration limit of 100mg/m3 in Shandong Province, the control effect of our company's denitrification system is difficult to meet its requirements. After the original denitrification system of our company's No.1 and No.2 production lines adopted sealing plugging and denitrification measures such as replacing, repositioning the spray gun and reducing the oxygen content, the concentration and amount of NOx emission was greatly reduced, which met the requirements of the new NOx concentration emission standard, and the production cost was also saved. Only the sewage charge can save more than CNY 400 000 per year.

Key words: nitrogen oxide atomization effect ammonia escape denitrification transformation
