Flue gas purification device

1. A flue gas purification device with a scrubber tower ( 10 ), which scrubber tower ( 10 ) comprises:

1.1 a flue gas entrance ( 12 ) and flue gas exit ( 14 ),

1.2 a liquid entrance ( 18 ) and a liquid exit,

1.3 a contact area ( 10 a ) for said flue gas and said liquid between said flue gas entrance and said liquid entrance ( 18 ),

1.4 a collecting basin ( 30 ) for said liquid below said contact area ( 10 a ), which collecting basin ( 30 ) being equipped with

1.4.1 aeration means ( 32 ) and

1.4.2 a bottom ( 34 ) or side wall ( 34 f , 34 s ), permeable to said liquid,

wherein the collecting basin ( 30 ) is arranged in fluidic connection with a channel ( 50 ) transporting liquid from a first section ( 50 f ) adjacent to a first side of the basin ( 30 ) to a second section ( 50 s ) adjacent to a second side of said basin ( 30 ) opposite to said first side of said basin ( 30 ), wherein the collecting basin ( 30 ) is part of the channel ( 50 ).

2. The flue gas purification device according to claim 1 , wherein at least one of the bottom ( 34 ) or side-walls ( 34 f , 34 s ) is designed according to at least one the following designs: perforated plate, three-dimensional profile with flow-through openings, sphere packing, valve.

3. The flue gas purification device according to claim 1 , further comprising at least one distributor ( 20 ), arranged above said collecting basin ( 30 ) and through which or adjacent to which the liquid may flow downwardly into the collecting basin ( 30 ).

4. The flue gas purification device according to claim 3 , wherein the distributor ( 20 ) extends over at least 50% of a corresponding inner horizontal cross-section of said scrubber tower ( 10 ).

5. The flue gas purification device according to claim 3 , wherein the distributor ( 20 ) is designed to at least one of the following designs: perforated plate, three-dimensional profile with flow-through openings ( 26 ), sphere packing.

6. The flue gas purification device according to claim 3 , wherein the distributor ( 20 ) has one or more through holes in its boundary area or ends at a distance to an inner wall of the scrubbing tower ( 10 ) thus forming one or more flow-through openings ( 20 a ) for said liquid.

7. The flue gas purification device according to claim 3 , wherein the distributor ( 20 ) is arranged below the flue gas entrance ( 12 ).

8. The flue gas purification device according to claim 1 , wherein the collecting basin ( 30 ) is arranged above the channel ( 50 ).

9. The flue gas purification device according to claim 1 , wherein the channel ( 50 ) has a deepened bottom extension below said collecting area compared with its first and second sections ( 50 f , 50 s ).

10. The flue gas purification device according to claim 1 , wherein the liquid is seawater.
