Claim Text:
1. A centrifugal separator for separating particles from a fluid, the centrifugal separator comprising: a tubular housing comprising an inflow opening at a first axial end of the housing and an outflow opening at an opposing second axial end of the housing; wherein the tubular housing surrounds a longitudinal axis extending though the housing from the inflow opening to the outflow opening; wherein an axial, as used herein, is a direction parallel to the longitudinal axis; wherein a radial, as used herein, is a direction traverse to the longitudinal axis; an axial core arranged in an interior of the tubular housing and elongated along the longitudinal axis; guide blades, including a first guide blade and a second guide blade, each guide blade extending radially between the axial core and a radially inner side of the tubular housing; where the guide blades are for generating a turbulent flow in a fluid flowing into the housing through the inlet opening, wherein the guide blades each have a leading edge; wherein the guide blades are each arranged stationarily; an immersion tube arranged within the housing, extending axially from the outflow opening towards the inflow opening; wherein the leading edge of the first guide blade has a first spacing relative to a cross-sectional plane of the housing and the leading edge of the second guide blade has a second spacing relative to said cross-sectional plane of the housing, said cross-sectional plane substantially perpendicular to an inflow direction of the fluid, wherein the first spacing and the second spacing are different from each other such that the leading edge of the first guide blade is spaced axially away from the leading edge of the second guide blade relative to the longitudinal axis.
