摘　　要：用氨水吸收法脱除工业氮氧化物,随着氨水浓度增加,吸收效果呈现先升后降的趋势,氨水的质量分数控制在7%效果最好;随着温度的增加,吸收效果呈现先升后降的趋势,温度控制在25℃为宜;文丘里洗涤装置的液汽比应控制在80L·m^(-3),氧化度应控制在50%。实验室及车间实验结果表明,本工艺排放的氮氧化物指标合格。经文丘里洗涤后的气体经过一级水洗即可进行达标排放。With the increase of ammonia concentration,the absorption effect first rised and then decreased,the best effect was to control the mass fraction at 7%.With the increase of temperature,the absorption effect first rised and then decreased,and it was appropriate to control at 25℃.The liquid-vapor ratio of Venturi scrubber was controlled at 80L/m3 and oxidation degree was at 50%.After washed in the Venturi scrubber,the gas reached the discharge standard.
