Abstract

PENEIRA DE DIGESTOR PARA UM DIGESTOR DE POLPA DE CELULOSE CONTÍNUO. A invenção se refere a uma peneira para um digestor contínuo em que a polpa de celulose cozida é produzida. A peneira de digestor compreende um número de barras de peneira (41a, 42c, 42a) dispostas verticalmente no digestor contínuo e tendo ranhuras de retirada (S) entre as barras de peneira fixadas, através de cujas ranhuras de retirada o fluido de cozimento pode ser retirado da coluna de polpa (P) do digestor. Por ter cada segunda barra de peneira (42a, 42c) fixada disposta e rebaixada uma distância (D) em relação à barra de peneira vizinha (41a), uma aumentada capacidade de retirada para a peneira é obtida.
