Abstract
A flotation device for separating materials or mixtures of materials from suspensions includes a reaction and mixing space ( ) with eccentric inlet ( ) for the mixture of suspension particles with gas bubbles and for further transport into at least one centrally arranged vertical suspension distribution tube ( ), wherein the suspension distribution tube ( ) and the clarified fluid collecting tube ( ) are arranged adjacently, the plates ( ) surround the suspension distribution tube ( ) and the clarified fluid collecting tube ( ) in an annular manner; and every second annular plate space ( ) between adjacent plates ( ) is connected to the suspension distribution tube ( ) and every other space ( ) between plates is connected to the clarified fluid collecting tube ( ), so that the flow takes place out of one space ( ) between plates from the inside towards the outside to the separating space ( ), and subsequently into an adjacent space ( ) between plates from the outside towards the inside. The substantive advantages of the invention are in that by combination of the plate arrangement with the eccentrically loaded reaction and mixing space, improved flocculation and thus better processing values are obtained in the filtrate. Better separation values are obtained by separation using the double-plate principle.
