Abstract:
1. A mixing reactor ( 12 ) for mixing a liquid and a solid into each other in a fluidized bed, for clarification the solution that is formed and discharging the clarified solution from the reactor, whereby the reactor is composed of three sections, the lowermost of which is essentially a cylindrical reaction section ( 14 ) for the formation of a fluidized bed, attached to the upper part of the reaction section is a calming section ( 18 ) which widens conically upwards, and connected to the upper part of the latter there is a cylindrical clarification section ( 22 ), the diameter of which is the same as the upper section of the calming section, characterised in that the lower section of the reaction section ( 14 ) is equipped with a solution feed connection ( 13 ) and the clarification section ( 22 ) has a solution discharge unit ( 23 , 32 ) located below the liquid surface (E), the discharge opening ( 24 , 33 ) of which is essentially on the central axis of the reactor (D), and that at least one guiding element ( 25 , 26 , 27 , 34 ) for directing the solution flow is located in the vicinity of the discharge opening.
