APPARATUS FOR DEGASSING AN AQUEOUS SUSPENSION CONTAINING PULP FIBRES

摘要

An apparatus for degassing an aqueous suspension containing pulp fibres, the apparatus comprising an elongated horizontal reservoir (1) and a bypass manifold (2) extending into the reservoir. The bypass manifold (2) is placed inside the reservoir (1) such that it it positioned substantially within the aqueous suspension at the bottom of the reservoir, the manifold thus decreasing the flow cross-sectional area of the aqueous suspension at the inlet end of the bypass manifold (2) in the reservoir (1).
