PCT No. PCT/SE87/00168 Sec. 371 Date Nov. 13, 1987 Sec. 102(e) Date Nov. 13, 1987 PCT Filed Apr. 1, 1987 PCT Pub. No. WO87/06281 PCT Pub. Date Oct. 22, 1987.An apparatus having a liquid-permeable belt for receiving cellulose pulp, a liquid supply device for discharging treatment liquid on the cellulose pulp, and a container extending across the entire width of the belt for collecting treatment liquid penetrating the belt. The container is adapted to maintain a treatment liquid level at such a distance from the belt so that the formation of foam from treatment liquid is reduced. The container includes a liquid outlet for discharging the treatment liquid and a vapour outlet for discharging vapours and gases from the bottom of the container. The vapour outlet communicates with a passageway within the container, which passageway is formed as a pipe or is partially defined by a container wall. A deflector can be provided on the container for operatively deflecting treatment liquid away from the passageway. |
