Third, the black liquor extraction process description

Linter pulp by alkaline cooking goals down at the pool, with adjusted diluted black liquor concentrated to 3-5%, by pumping to the high stability of the headbox, headbox by a high stability against gravity to ramp spiral concentrator, through oblique spiral pre-concentrate (concentration 8-12%) flows into the # 1 single spiral squeeze pulp slurry is adjustable by varying the pitch of the screw auger extrusion in a single screw forward process, the excess water through an external filter drum the sieve removal, more than 45% of the concentration of the slurry after dehydration through the discharge port, by gravity from the plane, falling dilution screw conveyor, high concentration slurry is added to dilute the screw conveyor and crushed black concentration was adjusted to 10-14% into the # 2 single spiral squeeze pulp concentrated again to a concentration of more than 45%, after falling into a slurry dewatering the slurry tank for subsequent refining process. Spiral ramp, # 1 single spiral discharged black liquor recovered by filtration evaporate into the station, # 2 single screw slurry used to dilute black liquor discharged into the spiral ramp before.
