摘　　要：氨法脱硫尾吸装置利用氨水中的NH 3吸收硫酸尾气中的SO_(2),尾吸系统出口尾气中的SO_(2)小于15 mg/Nm 3,副产硫酸铵。氨法脱硫装置在运行中出现了泡沫、腐蚀、晶浆液颜色发黄、尾气拖尾等问题。通过工艺调整、设备改造等方法,解决了上述问题,使氨法脱硫装置得到了稳定的运行。The ammonia desulfurization tail suction device uses NH 3 in ammonia water to absorb SO_(2) in the sulfuric acid tail gas,and the SO_(2) in the export tail gas of the tail suction system is less than 15 mg/m 3,and the byproduct is ammonium sulfate.In the operation of ammonia desulfurization device,there are some problems such as foam,corrosion,yellow slurry color and tail tail.Through process adjustment,equipment transformation and other methods,the above problems are solved,and the ammonia desulfurization device gets stable operation.
