Scrubber tray and a wet scrubber tower comprising such scrubber tray

A scrubber tray for a wet scrubber tower (10) of a flue gas purification device, the scrubber tray comprising

• a) a plurality of spindles (32) arranged across an inner horizontal cross section of the wet scrubber tower (10), the plurality of spindles (32) including adjacent spindles (32) spaced apart from each other by a horizontal distance (d), wherein
• b) at least some of the plurality of spindles (32) are pivot-mounted to allow a rotative movement of the respective spindle (32) around a corresponding spindle axis (A) and to arrange the respective spindle (32) at a predetermined rotation angle,
• c) each of at least some of the plurality of spindles (32) is equipped with at least two protrusions (36), each of the at least two protrusions extending outwardly from the respective spindle (32) and being disposed on a line parallel to a spindle axis (A) that is arranged in a longitudinal direction, the at least two protrusions being separated from each other in the longitudinal direction, and
• d) the plurality of spindles (32) and the at least two protrusions (36) are shaped and arranged such that a flow-through opening (40) is defined between the adjacent spindles and between the at least two protrusions (36) of the adjacent spindles (32), the flow-through opening (40) having a flow-through area comprising between 10% and 80% of the inner horizontal cross section of the wet scrubber tower (10), independently of the respective rotation angles of the plurality of spindles (32).
