REACTOR FOR TREATING A PULP WITH A GAS COMPRISING A DEGASSING OUTLET MEMBER

摘要

A reactor for treating pulp with gas, comprising a pressurized vessel (1) and an outlet member (2) at its top, and with a blow line (3). According to the invention, the outlet member has a housing (5) which is in open communication with the vessel and to which the blow line is connected, a rotor being arranged in the housing for throwing pulp in the direction of the inner side of the housing so that the pulp is discharged to the blow line, while gas accumulates in the centre of the housing (5). There is also an outlet channel (20) which extends through the rotor shaft (27) from the centre of the rotor (10), and an outlet line (24) which is in communication with the outlet channel (20) for removal of gas from the centre of the housing (5).
