Abstract
An apparatus for treating and discharging a medium, such as cellulosic fibrous material, in a container or bleaching tower includes an agitating and treating arm coupled to a rotating discharge pipe. A treatment medium or a diluting liquid is dispensed through orifices in the agitating and treating arm disposed in the bottom of the container. The cellulosic fibrous material suspension is discharged from the bleaching tower. The treatment medium or the diluting liquid is fed through the orifices in the agitating and treatment arms as a function of the state variables of the treatment medium and/or the medium to be discharged. The orifices include an obturator to open and close the orifices as a function of the pressure differential between the treatment medium and the medium to be discharged in the area of obturators during the discharge operation.
