<p>In a vertical vortex cell column, especially for the fluidisation of solid particles in a carrier flow, with supply arrangement for the liquid to be treated and removal arrangement for the treated liquid in the upper part of the column, supply arrangement for the liquid to be treated and delivery arrangement for the treated material flow, there is a multiple number of plates which leave free one or more openings for the throughflow of at least one material flow, arranged within the column. In order to achieve improvement of the operation, greater dimensioning of the cross-section of the column and simplified installation of the plates in the column the plates are formed as generated surfaces of truncated right circular cones with an opening angle of about 60 to 150.degree.C and arranged symmetrically to the longitudinal axis of the column and with their concave or convex sides alternatingly upward. The plates possess central openings for through passage of a material flow and provide between the circumferential curves of the notional cone base surfaces of the plates and the inner column circumference annular passageways for through passage of a material flow.</p> |
