A device (1) for extracting the solid particles from the exhaust gas of a heat engine (30) equipped with a fresh air intake circuit (32), said device (1), arranged downstream from the collector (31) collecting exhaust gas from the heat engine (30), comprising a turbine (2), a chamber (4) forming a buffer zone for controlling the flow of exhaust gas, and at least one centrifugation chamber (5) equipped with a rotor (6) and a particle collector (7), the rotor (6) of the centrifugation chamber (5) being coupled with the shaft of the turbine (2) arranged upstream from the centrifugation chamber (5) and from the chamber (4) forming a buffer zone, in order to cause the rotation of the rotor (6) of the centrifugation chamber (5) and the separation of the particles from the gas flow. The device (1) comprises, downstream from the centrifugation chamber (5), an exhaust gas recirculation circuit (8) which can be connected to the fresh air intake circuit (32) of the heat engine (30), said recirculation circuit (8) being equipped with cooling means (9).
