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.

Method for converting an up-flow tower for cellulose pulp to a down-flow tower

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.
