Abstract

A cyclone separator has a cyclone arrangement with individual cyclones each provided with a cell tube and guide device. The guide device causes a gas stream passing through the cell tube to rotate. At least one particle discharge is positioned perpendicularly to a longitudinal axis of the cyclone separator and discharges separated particles that have been separated from the gas stream in the cyclone arrangement. The cell tubes, for a targeted discharge of the separated particles, each have at least one particle outlet opening that is facing the particle discharge. The particle outlet openings of at least some of the individual cyclones, neighboring each other in the direction of a first perpendicular line that is perpendicular relative to the longitudinal axis of the cyclone separator, are displaced relative to each other in the direction of the longitudinal axis of the cyclone separator.

First claim

What is claimed is:

1. A cyclone separator for separating liquid and/or solid particles from a gas stream, the cyclone separator comprising:
a cyclone arrangement in the cyclone separator with individual cyclones each comprising a cell tube with a guide device, wherein the guide device is designed such that a gas stream passing through the cell tube in a flow direction of the gas stream is caused to rotate;
a particle discharge on the cyclone separator positioned perpendicularly to a longitudinal axis of the cyclone separator and adapted to discharge separated particles that have been separated from the gas stream by rotation in the cyclone arrangement, wherein the cell tubes, for a targeted discharge of the separated particles to the particle discharge, each have at least one particle outlet opening that is facing the particle discharge;
wherein the particle outlet openings of at least some of the individual cyclones, neighboring each other in the direction of a first perpendicular line that is perpendicular relative to the longitudinal axis of the cyclone separator, are displaced relative to each other in a direction of the longitudinal axis of the cyclone separator such that particles ejected from the particle outlet openings of individual cyclones will be guided into different planes offset relative to the longitudinal axis;
wherein a first subset of the individual cyclones is a plurality of cyclones having particle outlet openings arranged at a first location on the longitudinal axis of the cyclone separator; and
a second subset of the individual cyclones is a plurality of cyclones having particle outlet openings arranged at a second location on the longitudinal axis of the cyclone separator, the second location offset from the first location along the longitudinal axis of the cyclone separator;
wherein individual cyclones of the first and second subset are alternately arranged such that individual cyclones of the first subset are immediately neighbored by individual cyclones of the second subset such that the particle outlet openings of the individual cyclones neighboring each other in the direction of the first perpendicular line and/or the particle outlet openings of the individual cyclones neighboring each other in the direction of the second perpendicular line are displaced from each other alternatingly; a first cyclone component and a second cyclone component arranged downstream in the flow direction of the gas stream relative to the first cyclone component, wherein the cell tubes are associated with the first cyclone component and the second cyclone component comprises immersion tubes, wherein the immersion tubes have a central outlet arranged downstream in the flow direction of the gas stream for discharging the purified gas stream, wherein the immersion tubes are disposed in the cell tubes, respectively, wherein the immersion tubes each have a downstream end in the flow direction of the gas stream and the cell tubes each have a downstream end in the flow direction of the gas stream, wherein the downstream ends of the immersion tubes are connected at least partially with the downstream ends of the cell tubes, respectively.

2. The cyclone separator according to claim 1 , wherein
the individual cyclones that in a vertical direction of the cyclone arrangement are arranged on top of each other are displaced relative to each other in the direction of the longitudinal axis of the cyclone separator.

3. The cyclone separator according to claim 1 , wherein
the displacement of the particle outlet openings in the direction of the longitudinal axis of the cyclone separator is realized by slanted positioning of the longitudinal axis of the cell tubes relative to the longitudinal axis of the cyclone separator.

4. The cyclone separator according to claim 1 , wherein
a magnitude of the displacement of the particle outlet openings in the direction of the longitudinal axis of the cyclone separator is selected as a function of the number of the individual cyclones neighboring each other and/or a distance of the particle discharge opening relative to the particle discharge.

5. The cyclone separator according to claim 1 as a pre-separator of an air filter system for an internal combustion engine of a vehicle.

6. The cyclone separator according to claim 1 as a pre-separator of an air filter system for an internal combustion engine of an agricultural machine or a truck.

7. The cyclone separator according to claim 1 , wherein
the particle outlet openings of at least some of the individual cyclones neighboring each other in a direction of a second perpendicular line are displaced relative to each other in the direction of the longitudinal axis of the cyclone separator,
wherein the second perpendicular line is arranged perpendicularly relative to the longitudinal axis of the cyclone separator and perpendicularly relative to the first perpendicular line.

8. The cyclone separator according to claim 7 , wherein
the second perpendicular line is extending in a transverse direction of the cyclone arrangement.

9. The cyclone separator according to claim 1 , wherein
a longitudinal axis of the cell tubes is arranged parallel to the longitudinal axis of the cyclone separator and the displacement of the particle outlet openings in the direction of the longitudinal axis of the cyclone separator is realized by a displacement of the particle outlet openings in the direction of the longitudinal axis of the cell tubes.

10. The cyclone separator according to claim 9 , wherein
the displacement of the particle outlet openings in the direction of the longitudinal axis of the cell tubes is realized by a different length of the neighboring cell tubes or by an axial displacement of the individual cell tubes relative to each other.

11. A cyclone separator for separating liquid and/or solid particles from a gas stream, the cyclone separator comprising:
a cyclone arrangement in the cyclone separator with individual cyclones each comprising a cell tube with a guide device, wherein the guide device is designed such that a gas stream passing through the cell tube in a flow direction of the gas stream is caused to rotate;
a particle discharge on the cyclone separator positioned perpendicularly to a longitudinal axis of the cyclone separator and adapted to discharge separated particles that have been separated from the gas stream by rotation in the cyclone arrangement, wherein the cell tubes, for a targeted discharge of the separated particles to the particle discharge, each have at least one particle outlet opening that is facing the particle discharge;
wherein the particle outlet openings of at least some of the individual cyclones, neighboring each other in the direction of a first perpendicular line that is perpendicular relative to the longitudinal axis of the cyclone separator, are displaced relative to each other in a direction of the longitudinal axis of the cyclone separator such that particles ejected from the particle outlet openings of individual cyclones will be guided into different planes offset relative to the longitudinal axis;
