METHOD OF STIRRING HYDRATE PULP Russian patent published in 1996 - IPC

FIELD: paper-making industry. SUBSTANCE: method includes loading pulp into decomposer with conical bottom and central air lift; feeding compressed air into lower section of air lift at the point located at minimum distance from the bottom end of the air lift, which provides a steady circulation of pulp upwards along air lift under optimal mixing conditions; interrupting, at least for a part of consequent stirring period, feeding compressed air into this part of air lift and feeding that into another, higher positioned part of air lift at the point whose location is determined by decrease of compressed air pressure in the air network and/or increase in consistency of pulp being stirred. EFFECT: improved stirring process. 1 dwg
