ACOUSTIC CYCLONE Russian patent published in 2006 - IPC B04C9/00 B04C11/00 

FIELD: chemical industry; textile industry; food industry; light and other industries; dust trapping equipment for purification of dusty gases.

SUBSTANCE: the invention is pertaining to dust trapping equipment, in particular, to the acoustic cyclones and may be used in chemical, textile, food, light and other industries for purification of the dusty gases. The acoustic cyclone contains; a body consisting of a cylindrical and a conical parts; located in its upper part a peripheral inlet of a gas stream and an axial outlet branch pipe of the purified gas, a an acoustic column. The lower part of the acoustic column is connected to the axial outlet branch pipe of the purified gas and contains a conical deflecting washer mounted with its great base on the lower base of the acoustic column. The vacuity formed by the surfaces of the deflecting washer and the column is linked through a bypass tap to the peripheral inlet of a gas stream. At that in the upper art of the acoustic column there is the outlet branch pipe of the purified gas and the acoustic oscillations generator coupled to a control unit. The technical result is an increased effectiveness of dust trapping.

EFFECT: the invention ensures an increased effectiveness of dust trapping.
