Abstract

A cyclone separator for separating liquid and/or solid particles from a fluid is provided with three or more cyclone cells that each have a cell pipe provided with a guiding device. The guiding devices cause the fluid to rotate and to separate the particles from the fluid by the rotation of the fluid. The cell pipes each have a particle exit opening for letting out the particles that have been separated by rotation from the fluid. One or more particle outlets are provided to discharge from the cyclone separator the particles that have exited from the cell pipes.

First claim

What is claimed is:

1. A cyclone separator for separating liquid and/or solid particles from a fluid, the cyclone separator comprising:
three or more cyclone cells each comprising
a cell pipe provided with a guiding device,
wherein the cell pipe surrounds a longitudinal axis of the cyclone cell corresponding to a flow direction through the cyclone separator;
wherein the guiding devices each are configured to cause the fluid to rotate about the longitudinal axis and to separate the particles from the fluid by rotation of the fluid, and
wherein the cell pipes each comprise
a particle exit opening for ejecting the particles that have been separated by rotation from the fluid;

a housing surrounding and supporting the three of more cyclone cells, the housing including
one or more particle outlets configured to discharge from the cyclone separator housing the particles that have exited from the cell pipes;

wherein the three or more cyclone cells include first cyclone cells arranged side by side in a first group,
wherein the guiding devices of the first cyclone cells are configured to cause the fluid to rotate in a first rotation direction,
wherein a first particle outlet of the more particle outlets of the housing is offset horizontally in a direction traverse to a direction of gravity and traverse to the longitudinal axis from the first cyclone cells,
and

wherein the cyclone separator further includes one or more second cyclone cells configured as a counter-rotating cyclone cells and arranged side by side in a second group separate from the first group,
wherein the guiding device of said counter-rotating cyclone cell is configured to cause the fluid to rotate in a second rotation direction opposite to the first rotation direction,
wherein a second particle outlet of the one or more particle outlets of the housing is offset horizontally in a direction traverse to the direction of gravity and traverse to the longitudinal axis from the second cyclone cells,
wherein particles exiting from the particle exit openings of the cell pipes of first cyclone cells are ejected to travel in a first horizontal direction, traverse to gravity and traverse to the longitudinal axis, towards the first particle outlet of the housing,
wherein particles exiting from the particle exit openings of the cell pipes of second cyclone cells are ejected to travel in a different second horizontal direction, traverse to gravity and traverse to the longitudinal axis, towards the second particle outlet of the housing.

2. The cyclone separator according to claim 1 , wherein
a number of the one or more second cyclone cells and/or a position of the one or more second cyclone cells in the cyclone separator and an orientation of the particle exit openings of the cell pipes of the first cyclone cells are matched relative to each other such that particle accumulations in the cyclone separator are reliably prevented.

3. The cyclone separator according to claim 1 , wherein
the cyclone separator comprises an area located in an ejection direction of the particles that are exiting from the particle exit openings of the cell pipes of the first cyclone cells and
wherein the one or more second cyclone cells are arranged in said area of the cyclone separator.

4. The cyclone separator according to claim 1 , wherein
the particle exit openings of the cell pipes of the first cyclone cells and of the one or more second cyclone cells are oriented toward the one or more particle outlets.

5. The cyclone separator according to claim 1 , wherein
approximately one half of the three or more cyclone cells are in the form of the first cyclone cells and
approximately one half of the three or more cyclone cells are in the form of the one or more second cyclone cells.

6. The cyclone separator according to claim 1 , wherein
fewer of the one or more second cyclone cells than of the first cyclone cells are arranged in the cyclone separator.

7. The cyclone separator according to claim 1 , wherein
a number of the one or more second cyclone cells arranged in the cyclone separator relative to a number of the first cyclone cells arranged in the cyclone separator corresponds to a ratio of approximately one to ten up approximately one to one.

8. The cyclone separator according to claim 1 , wherein
an ejection direction of the particles exiting from the particle exit openings of the cell pipes of first cyclone cells and of the one or more second cyclone cells is oriented in a direction toward the one or more particle outlets.

9. The cyclone separator according to claim 1 , wherein
an ejection direction of the particles exiting from the particle exit openings of the cell pipes of the first cyclone cells and of the one or more second cyclone cells is oriented in a direction toward a center of the cyclone separator.

10. The cyclone separator according to claim 1 , wherein
the one or more particle outlets are distributed uniformly across one side of the housing.

11. The cyclone separator according to claim 10 , wherein
the housing comprises a long side and a short side,
wherein said one side of the housing is the long side of the housing.

12. The cyclone separator according to claim 1 , wherein
the housing comprises a long side and a short side,
wherein the one or more particle outlets are arranged centrally on the long side or on the short side.

13. The cyclone separator according to claim 1 , wherein
the three or more cyclone cells are oriented in a flow direction of the fluid passing through the cyclone separator and are arranged parallel to each other,
wherein the one or more particle outlets are oriented in a direction transverse to the flow direction of the fluid passing through the cyclone separator.

14. The cyclone separator according to claim 13 , wherein
the one or more particle outlets are oriented in a direction of gravity.

15. The cyclone separator according to claim 1 embodied as a pre-separator for an air filter system of a power engine or a compressed air compressor.

16. A filtering device comprising:
a filter housing with a raw-side inlet and a clean-side outlet for a medium to be filtered;
a cyclone separator according to claim 1 arranged at the raw-side inlet of the filter housing and configured as a prefilter.
