Abstract

A liquid separation device for the separation of liquid or liquid mist from a gas, with at least one pair of basic carriers being a first and a second plate-shaped basic carrier, where in each of the first and the second basic carrier, at least two separator elements are formed. The separator elements each have a passage pipe with a gas inlet and a gas outlet, which are arranged at opposite sides of the respective plate-shaped basic carrier in such a way that the passage pipe extends through the respective plate-shaped basic carrier. The first and the second basic carrier being arranged one next to the other in flow direction of the gas. Each of the two separator elements in both basic carriers in which the separator elements are arranged adjacent to each other, with their passage pipes form continuous flow paths for the gas. At least in the transition area of a flow path from an upstream passage pipe to an adjacent downstream passage pipe, the inner diameter of the downstream passage pipe is larger than the inner diameter of the adjacent upstream passage pipe.

First claim

The invention claimed is:

1. A liquid separation device for the separation of liquid or liquid mist from a gas, with
at least one pair of basic carriers comprising a first and a second plate-shaped basic carrier,
where in each of the first and the second basic carrier, at least two separator elements are formed,
where the separator elements each comprise a passage pipe with a gas inlet and a gas outlet, which are arranged at opposite sides of the respective plate-shaped basic carrier in such a way that the passage pipe extends through the respective plate-shaped basic carrier,
wherein
the first and the second basic carrier fit together one directly behind the other in a single gas flow direction, and
that each two separator elements in both basic carriers, respectively, fit together one directly behind the other, with their passage pipes forming continuous flow paths for the gas,
where at least in a transition area of a flow path from an upstream separator element to an adjacent downstream separator element, the inner diameter of the downstream separator element is larger than the inner diameter of the adjacent upstream separator element.

2. The liquid separation device according to claim 1 , wherein at least in the area of the transition of one flow path of an upstream passage pipe to the adjacent downstream passage pipe, the inner diameter of the downstream passage pipe is larger than the inner diameter of the upstream pipe by ≥10%.

3. The liquid separation device according to claim 1 , wherein the inner diameter at the transition of one flow path from an upstream flow pipe to an adjacent downstream flow pipe changes abruptly.

4. The liquid separation device according to claim 1 , wherein the basic carriers arranged one next to the other are adhesively connected but not over their entire surface.

5. The liquid separation device according to claim 1 , wherein at least in one, several or all passage pipes of the separator elements, a gas guiding element with guiding surfaces is arranged between the gas inlet and the gas outlet, the guiding surfaces of which together with the inner surface of the passage pipe divide the flow path in the passage pipe into at least two partial flow paths for the gas.

6. The liquid separation device according to claim 5 , wherein the gas guiding elements are only formed in the passage pipes of the second basic carrier.

7. The liquid separation device according to claim 5 , wherein at least one, several or all gas guiding elements are realized as helical segments with helicoids, the helicoids of which together with the inner wall of the passage pipe form at least two helical partial flow paths for the gas.

8. The liquid separation device according to claim 7 , wherein the helical segments of two passage pipes following each other in the flow direction comprise different wall thicknesses.

9. The liquid separator according to claim 7 , wherein in at least one, several or all flow paths, in each of the passage pipes arranged one adjacent to the other forming a flow path, at least one of said helical segments are arranged,
wherein the helical segments of passage pipes arranged one immediately after another and forming a flow path may immediately adjoin one to the other and/or
the inlet-sided edge of the helical segment in the downstream passage pipe is rotated relative to the outlet-sided edge of the helical element in the upstream passage pipe by a predetermined angle α.

10. The liquid separation device according to claim 9 , wherein an outlet-sided edge of the helicoid of the helical segment in an upstream passage pipe and an inlet-sided edge of the helicoid of the helical segment in the adjacent downstream passage pipe are rotated one relative to the other around the central axis of the passage pipes of the separator elements, by 0°, 45°, 90° or 135°, respectively.

11. The liquid separation device according to claim 7 , wherein the direction of rotation in two helical segments arranged one behind the other in a flow path is identical or inverse.

12. The liquid separation device according to claim 1 , wherein in a flow direction of the gas in front of the first basic carrier and/or in a flow direction of the gas behind the second basic carrier at least one further plate-shaped basic carrier is arranged, in which at least one further separator element is arranged, with the further separator element comprising a further passage pipe with a gas inlet and a gas outlet, which are arranged on different sides of the further plate-shaped basic carrier in such a way that the further passage pipe extends through the further plate-shaped basic carrier and together with one of the passage pipes of the separator elements in the first and second basic carrier forms at least one common flow path for the gas.

13. The liquid separation device according to claim 1 , wherein in at least one, several or all basic carriers between 2 and 80 separator elements are arranged one next to the other in the plane of the basic carrier.

14. The liquid separation device according to claim 1 , wherein the separator elements arranged in one, several or all basic carriers or all separator elements arranged in one basic carrier are designed identical and that they are only different with respect to the arrangement of the gas guiding elements.

15. The liquid separation device according to claim 1 , wherein the liquid is water that is separated from exhaust gases of a fuel cell.

16. The liquid separation device according to claim 1 , wherein the liquid is oil that is separated from blow-by gases of an internal combustion engine.

17. The liquid separation device according to claim 16 , wherein the liquid separation device is arranged at or in a valve cover housing, wherein the valve cover housing is divided into two partial spaces by the basic carriers so that a fluidic connection between the two partial spaces is only possible through the passage pipes.
