1. A device for removing solids from a gas stream, comprising: a longitudinal hollow element comprising an inlet, a first outlet and second outlet;a rotation-generating element which is positioned in the longitudinal hollow element and which causes the gas stream to rotate around a centerline of the hollow element, said rotation-generating element being arranged between the first outlet and the second outlet in the longitudinal direction of the hollow element and comprising a central axial passage which is fluidly connected to the first outlet by an extraction line, said first outlet being arranged between the inlet and the rotation-generating element in the longitudinal direction of the hollow element;wherein a section of the hollow element between the second outlet and the rotation-generating element has a decreasing inner circumference in the longitudinal direction of the hollow element towards said second outlet, and wherein the second outlet of the longitudinal hollow element is fluidly connected to a container for accumulation of the solids, such that the solids are transported by help of a minor fraction of the gas stream into the container during use; anda housing within which the longitudinal hollow element is positioned, the housing having at least a first outlet and forming a space between an inner surface of the housing and an outer surface of the hollow element, said space being in fluid contact with the first outlet of the hollow element and the first outlet of the housing;wherein the interior of the container is fluidly connected to at least one of the space or the first outlet of the housing by a recycle conduit having a first end and a second end, the first end being arranged internal to the container and the second end being arranged downstream of the first outlet of the longitudinal hollow element, such that the minor fraction of the gas stream is extracted through the recycle conduit and routed to the first outlet of the housing during use. 2. A device according to claim 1, wherein the housing comprises an inlet which is in fluid contact with the inlet of the longitudinal hollow element. 3. A device according to claim 1, wherein the first end of the recycle conduit comprises an opening and the device further comprises a collar and a cap arranged in front of said opening such that solids are prevented from being entrained through the recycle conduit. 4. A device according to claim 3, wherein the cap is shaped as a hollow cone arranged with its apex in the upstream direction, and wherein the opening of the first end of the recycle conduit situated within the hollow and the collar is in the shape of a truncated cone. 5. A device according to claim 1, wherein the entire longitudinal hollow element is arranged within the housing, and the inlet and the first outlet of said hollow element are in fluid contact with the inlet and the first outlet of the housing, respectively. 6. A device according to claim 1, wherein the container comprises a solids outlet. 7. A device according to claim 1, wherein the container is defined by a section of the housing. 8. A device according to claim 1, wherein the longitudinal hollow element is removable from the housing. 9. A device according to claim 1, wherein the housing comprises a pipe element adapted for inline connection. 10. A device according to claim 9, wherein the pipe element is configured as one from the group consisting of I-shaped, T-shaped and Y-shaped.
