摘　　要：JY公司由于熟料产量由原设计4 800 t/d增加至5 800 t/d,系统NO_(x)排放本体浓度增大,而原有脱硝系统使用时间久,设备老化,喷枪位置不合理,喷枪结皮严重,雾化差等,在满足NO_(x)环保排放指标达到280 mg/m^(3)以下时,吨熟料氨水用量在2.6 kg/t。采用WIS-He SNCR精准脱硝系统、运用智能优化控制技术对生产线进行改造,同等条件下,单位熟料氨水用量降至2.02kg/t。Due to the increase in clinker production from the original design of 4800 t/d to 5800 t/d,JY Company has seen an increase in the concentration of NOx emissions from the system itself.Additionally,the original stripping system has been in use for a long time,with aging equipment,unreasonable spray gun positions,severe spray gun skinning,and poor at-omization.When meeting the NOx environmental emission standards of below 280 mg/m^(3),the amount of ammonia water used per ton of clinker is 2.6kg/t.Using the WIS-HeSNCR precision denitrification system and intelligent optimization con-trol technology,the production line was renovated.Under the same conditions,the amount of ammonia water used per ton of clinker was reduced to 2.02 kg/t.
