DESALTED RESIDUE TREATMENT

摘要

PROBLEM TO BE SOLVED: To prevent cement solidified matter from crumbling when the cement solidified matter after desalted residue treatment is stored outdoors. SOLUTION: A desalted residue generated when waste gas is subjected to desalting treatment with a cleaning device 73 is fed to an extrusion molding machine 87 by a desalted residue feeder 82 from a desalted residue hopper 81. And to the extrusion molding machine 87, cement and water are fed from a cement feeder 84 and a water feeder 85 respectively, and the desalted residue and cement are kneaded together with water. On this kneading, chlorine concentration in the desalted residue is detected by a chlorine concentration detector 95 and the adding quantity of the cement is adjusted according to the detection results. The cement is added so that chlorine concentration in cement formed matter of the desalted residue is 25 wt.% or less. And according to the chorine concentration in the desalted residue, control in which water is added by 20-50% from the water feeder 85 may be performed.
