A device for removing solid particles, particularly soot particles, from exhaust gas of an internal combustion engine, comprising an electrofilter including a plurality of filter tubes positioned parallel to each other, and a high voltage source, each filter tube including a separator tube connected to a positive terminal of said high voltage source and a corona discharge electrode axially extended in said separator tube and connected to a negative terminal of said high voltage source; a housing surrounding said filter tubes so that a hollow space extending approximately over the whole length of said filter tubes is defined between an inner surface of said housing and said filter tubes; and a centrifugal separator connected to said electrofilter in a direction of an exhaust gas flow, said centrifugal separator being formed as a multi-cyclone and including a plurality of cyclones arranged so that a number of cyclones correspond to each separator tube, each cyclone having in an axial direction thereof an exhaust gas inlet opening, each separator tube being immediately connected to said number of cyclones which are arranged on a circle concentrical to an axis of a respective separator tube.
