FIELD: engines and pumps. ^ SUBSTANCE: cyclone separator comprises a primary cyclone with the fist outside air intake and the first air discharge outlet. Note that the latter comprises a flow passage part with a perforated section, that makes its lateral wall, and a closed part on its bottom, a secondary cyclone communicating with the primary cyclone. It incorporates also a flow guide arranged above the fist discharge outlet to prevent abrupt change of the direction of airflow forced out from the first discharge outlet and to direct air blown out from the perforated part to the secondary cyclone. ^ EFFECT: higher efficiency of separation, lower noise. ^ 11 cl, 5 dwg |
