Apparatus for Engasen of fiber suspensions

Device (1) for degassing pulp suspensions (2, 2a, 2b), consisting of DOLLAR A - a preferably elongated and horizontal cylindrical, vessel (main tank) (3) with a horizontal or approximately horizontal container axis (3a); DOLLAR A - at least one disposed therein, an overflow (15) forming the partition wall (partition wall main) (16); DOLLAR A - mounted at least in each case one in the container (3) connection (4, 9, 18, 20, 20.1-20.3, 25, 25.1-25.2) for at least one fibrous suspension (2, 2a, 2b) (for at least one gas-free pulp suspension 2.2), (for a separated gas 7) and at least one means of the at least one overflow (15) separated, excess fibrous suspension (2.1); DOLLAR A - means for generating a negative pressure in the container (3), DOLLAR A wherein the tank (main tank) (3) in the direction of the container axis (3a) at least one further container (sub-tank) (3.1-3.8) is arranged downstream, which is preferably in the is constructed substantially like the main tank (3).
