Cyclone separator

1. A cyclone separator for separating liquid and/or solid particles from a gas stream, comprising:

a first cyclone component with at least one substantially cylindrically embodied cell pipe that includes a guide device by means of which the gas stream is caused to rotate for separating the particles;

a particle outlet for discharging the separated particles, and

a second cyclone component arranged downstream in the flow direction of the gas stream and including at least one immersion pipe,

wherein the immersion pipe is received in the cell pipe, is connected at its outflow-side end, viewed in the flow direction of the gas stream, at least partially with the outflow-side end of the cell pipe, viewed in the flow direction of the gas stream, and has a central outlet for discharging the purified gas stream;

wherein in a connecting area of the outflow-side end of the cell pipe and of the outflow-side terminal area of the immersion pipe at least one sealing element is arranged that connects the cell pipe and the immersion pipe seal-tightly with each other,

wherein the sealing element is substantially formed of at least one thermoplastic elastomer or rubber.

2. The cyclone separator according to claim 1 , wherein

the immersion pipe includes at its outflow-side end an immersion pipe plateau that extends substantially radially relative to an axial direction of the immersion pipe;

wherein the sealing element seal-tightly connects at least one area of the outflow-side end of the cell pipe with the immersion pipe plateau.

3. The cyclone separator according to claim 2 , wherein

the sealing element sealing the connecting area of the cell pipe and of the immersion pipe has at least one axial sealing surface extending in the direction of the axis of the cell pipe or in the direction of the axis of the immersion pipe or

the sealing element sealing the connecting area of the outflow-side end of the cell pipe and of the outflow-side terminal area of the immersion pipe has at least one radial sealing surface extending in the direction of the radius of the cell pipe or in the direction of the radius of the immersion pipe.

4. The cyclone preseparator according to claim 1 , wherein

the sealing element is releasably arranged on at least one area of:

the outflow-side end of the cell pipe or

the outflow-side terminal area of the immersion pipe.

5. The cyclone separator according to claim 1 , wherein

the sealing element is injection-molded to at least one area of:

the outflow-side end of the cell pipe or

the outflow-side terminal area of the immersion pipe, in particular on at least one area of the immersion pipe plateau.

6. The cyclone separator according to claim 1 , wherein

the cyclone separator is embodied as a multi-cell cyclone;

wherein the first cyclone component has a plurality of cell pipes;

wherein the second cyclone component has a plurality of immersion pipes; and

wherein the sealing element is arranged on each cell pipe or on each immersion pipe.

7. The cyclone separator according to claim 6 , wherein

the sealing elements on each cell pipe or each immersion pipe of said multi-cell cyclone are connected to each other like a mat, said connection facilitating exchange of the sealing elements.

8. The cyclone separator according to claim 1 , wherein

the cell pipe, for a targeted discharge of the particles that are separated by rotation to the particle outlet, includes at least one cutout at the outflow-side end;

wherein the outflow-side end ( 16 ) of this cutout is arranged at a spacing to the outflow-side terminal area of the immersion pipe ( 22 ).

9. The cyclone separator according to claim 1 , wherein

the cyclone separator is embodied as a preseparator; and

wherein the central outlet of the immersion pipe is connected to a raw-side inlet of a filter housing in which a primary filter element is received.
