The high-consistency bleaching tower is a bleaching reaction unit for high-consistency pulp, which is mainly applied to high-consistency hydrogen peroxide bleaching.
Pulp enters the tower from the top, retains inside the tower for a certain reaction time, and is discharged through the discharge screw at the bottom.Compared with medium-consistency hydrogen peroxide bleaching, high-consistency hydrogen peroxide bleaching can improve pulp brightness more effectively, reduce hydrogen peroxide consumption and lower bleaching cost.
