Process Practice of KR Desulphurization by Power Blasting
the best way to add desulfurizer is spray suction type,during production process by measures like adjusting the Angle of the desulphurization spray gun to be close to 90°
the relative height of the spray gun to be 500 mm
the injection point of the desulphurization agent to be within 1/2 radius
the particle size of the desulphurization agent to be no more than 2 mm
the injection speed to be 130-150 kg/min
the powder/gas ratio to be 75 kg/Nm
3
and the high-speed stirring time to be 4-6 minutes
etc
it solves the problems of low desulfurization efficiency caused by pipe clogging
splashing and unstable desulfurization yield in the actual production process
and gives full play to the advantages of desulfurization by spraying. Compared with the batch adding (gravity)method
