Abstract

The application relates to a liquid distributor ( 1 ) for supplying a liquid in a pressure-free manner over a surface area, having a distributor trough ( 2 ) with a trough base ( 3 ) which, for the purpose of discharging liquid, has an arrangement of holes ( 5 ), which extends over at least part of the surface of the trough base ( 3 ), having an inflow ( 4 ), via which a liquid which is to be distributed can be introduced in the distributor trough ( 2 ) such that the liquid introduced accumulates on the trough base ( 3 ), and having a retaining device with a retaining plate ( 7 ), which is arranged opposite the trough base ( 3 ) and at a distance apart therefrom, wherein distributing elements ( 6 ), which project from the retaining plate ( 7 ) in the direction of the trough base ( 3 ), each engage through an associated hole of the arrangement of holes ( 5 ) in the trough base ( 3 ) and are accommodated loosely therein such that the liquid accumulating on the trough base ( 3 ) can be discharged through free hole regions ( 10 ), which are not affected by the distributing elements ( 6 ) extending through the holes ( 5 ).

First claim

The invention claimed is:

1. A liquid distributor for supplying a liquid in a pressure-free, planar manner, having
a distributor trough with a trough base, which for the purpose of discharging the liquid, has an arrangement of holes, which extends over at least part of the surface of the trough base,
an inflow, via which the liquid which is to be distributed can be introduced in the distributor trough such that the liquid introduced accumulates on the trough base, and
a retaining device with a retaining plate, which is arranged opposite the trough base and at a distance apart therefrom,
wherein distributing elements, which project from the retaining plate in the direction of the trough base, each engage through an associated hole of the arrangement of holes in the trough base and are accommodated loosely therein such that the liquid accumulating on the trough base can be discharged through free hole regions, which are not affected by the distributing elements extending through the holes.

2. The liquid distribution according to claim 1 , wherein in the free hole areas, through which the liquid can be discharged, the hole wall and the outer surface of the distributing elements are spaced apart so as to ensure the capillary effect.

3. The liquid distributor according to claim 1 , wherein the distributing element, in a distributing element section engaging through the hole and associated hole have different cross-sectional shapes.

4. The liquid distributor according to claim 1 , wherein the distributing elements are detachably attached to the retaining plate.

5. The liquid distributor according to claim 1 , wherein the distributing elements are arranged on the retaining plate, each in an associated opening.

6. The liquid distributor according to claim 5 , wherein the distributing elements on the retaining plate are each pushed through the associated opening such that a distributing element head is arranged on the rear-side.

7. The liquid distributor according to claim 6 , wherein the rear-side of the retaining plate is arranged opposite a cover plate, which rests on the distributing element head sections of the pushed through distributing elements.

8. The liquid distributor according to claim 1 , wherein the retaining plate is arranged so as to be spaced apart from the trough base by means of one or more spacers.

9. The liquid distributor according claim 1 , wherein the retaining plate together with the distributing elements arranged thereon is arranged so as to be displaceable relative to the trough base with the arrangement of holes.

10. The liquid distributor according to claim 9 , wherein the retaining plate is displaceable based on the liquid entering the distributor trough and/or the liquid accumulating in the distributor trough.

11. The liquid distributor according to claim 1 , wherein the retaining plate is arranged in the distributor trough.

12. The liquid distributor according to claim 1 , wherein the distributing elements, in the area of a section projecting from the retaining plate which section engages through the associated hole in the trough base is realised as a pin or mandrel.

13. The liquid distributor according to claim 1 , wherein the retaining plate comprises at least one outlet opening, through which the liquid can reach the trough base.

14. An arrangement with a liquid distributor according to claim 1 and with a material exchanging surface or heat exchanging surface, onto which a liquid to be distributed can be areally discharged by means of the liquid distributor.
