Bleaching System
High-consistency hydrogen peroxide bleaching system
As a good chloride-free bleaching agent, hydrogen peroxide is used to bleach mechanical pulp, chemi-mechanical pulp and chemical pulp. Main equipment includes screw squeezer, heating screw, high-consistency mixer and high-consistency bleaching tower.
Features:
1. Less bleaching loss and strong technological adaptation;
2.Wastewater pollution load is low and easy to deal with.
3.High efficiency, less chemical dosage, full reaction and low residual rate of bleaching agent.
Applicable production scale: 50,000—100,000 tons/year
