After putting into operation, the concentration of smoke emission has been reduced to lower than 50 mg/m3(standard state), the control of bag dust collector to be simple, and its operation to be stable and re.

For this,the dust concentration in flue gas entering into the absorption tower has been decreased to 50 mg/m3,at the same time,the 50% dust removal efficiency of absorption tower isn\'t calculated again,this is reserved to treatment of the increased "spattered drops"of dust,to ensure the concentration of smoke emission to be less than 50 mg/m3.
