[0002] With the continuous improvement of environmental protection requirements, the SO2 content of flue gas emission outlet is required to be less than 35 mg / m 3 , and the total dust emission is required to be 5 mg / m 3 . In order to further develop, some enterprises increase the generator set under the condition that the total SO2 emission is unchanged, and it is necessary to further reduce the SO2 emission concentration. At present, some enterprises require that the SO2 emission is less than 15 mg / m 3 or 10 mg / m 3 .
