    摘要： The method is for converting a vertically standing up-flow tower by inserting a freely insertable pipe into the conical part of the up-flow tower the tower is converted to a down-flow tower where the tower can easily be restored to the up-flow tower and optimized with regards to a minimized stagnation volume in the tower. The upper open end of the pipe is disposed at a first distance (A) from the lower part of the conical inlet part. The first distance (A) is less than the total vertical extension (B) of the conical inlet part. The cellulose pulp establishes a self-forming stagnation zone around the pipe at a lower part of the down-flow tower.

    摘要： Process and device for mixing fluid into a pulp suspension of cellulose-containing fiber material, in which the pulp suspension is pumped in through a pump inlet (17), brought into rotation and, at the desired reaction pressure, mixed with the said fluid while passing through a reaction sector comprising a stator shell (1), a rotor (7) which is coaxial therewith, and at least one fluid inlet (23), after which the pulp mixture leaves the reaction sector through a pulp outlet (20), in which the fluid, via the said fluid inlet (23), is supplied in the vicinity of the center of rotation of the rotating pulp suspension, where the local pressure in the pulp suspension is lower, due to the centrifugal force increasing radially outwards, than the reaction pressure prevailing at the periphery of the pulp suspension.

    摘要： An apparatus for mixing a first fluid into a second fluid that comprises a housing (1) having a flow chamber (39) for the second fluid, a flow restrictor member (6) in the flow chamber, and holes (18) for introducing the first fluid into at least one gap (15, 16) between the flow restrictor member and those walls (5, 10) of the flow chamber (39) facing towards the flow restrictor member. The flow restrictor member and flow chamber, in a plane transversely to the principal flow direction (31) of the second fluid, each has the shape of a wedge. Gaps (15, 16) are formed between each of those two sides of the flow restrictor member that converge in a wedge shape and those walls of the wedge-shaped chamber facing towards the flow restrictor member. The holes (18) for introducing the first fluid are disposed in the region of the gaps (15, 16).

    摘要： An apparatus for fluidizing, degassing and pumping a suspension of fibrous cellulose material is described which comprises a housing, a fluidizing rotor and an impeller of radial type, said housing having a cylindrical portion for the rotor, a portion for the impeller which is radially enlarged in relation to the cylindrical portion, a wall closing one end of the housing and a shaft rigidly connected to the impeller, an axial inlet for suspension being disposed at the cylindrical portion, and a radial outlet for suspension at the radially enlarged portion. The apparatus has also a degassing system for removing gas which collects in front of the impeller and comprising an opening in the impeller and the wall, the impeller having a hub, a partition and forward and rear blades. Furthermore, the impeller is provided with a concentric, circular inlet for the continuous supply of suspension to the rear blade space, the rear blades being arranged to exert a pump action on the suspension supplied to the apparatus.

    摘要： This is a device and a method for withdrawing cellulose pulp with a pulp concentration of 8-14% from a cylindrical storage tower. The storage tower has a plane bottom and with a diameter that exceeds 3 meters. A pipe is arranged through the wall of the storage tower that is parallel to the bottom of the tower and directed towards the center of the tower. The pipe has at one of its ends an obliquely cut opening that faces upwards in the tower. The pipe is attached at its other end to an MC pump to be able to pump out cellulose pulp from the storage tower.

    摘要： The reactor comprises a pressurized vessel having an outlet member at its top and further including a blow line. The outlet member includes a housing that is in fluid communication with the vessel and to which the blow line is connected. A rotor is arranged in the housing for urging pulp in a direction of an inner side of the housing so that the pulp is discharged to the blow line while gas accumulates in the center of the housing. An outlet line is in fluid communication with an outlet channel for removing the gas from the center of the housing.
