Abstract

PURPOSE: To improve profitability through reduction of equipment cost and omission of procedure for disposal of dust, by removing alkali from the dust through washing with water and dehydration of the dust exhausted from an electric precipitator, which is used in main exhauster for sintering, so as to make the dust usable once again as raw material for sintering.
CONSTITUTION: Dust which is discharged from a sintering machine and collected by an electric precipitator and contains iron and a large quantity of alkali (present as NaCl, KCl etc.) is washed with water to remove alkali, and is dehydrated, so that it is reutilized as raw material for sintering.
