COMBINED CYCLONE WITH ACOUSTIC FLUID SPRAYING Russian patent published in 2009 - IPC B04C5/12 

FIELD: instrument making.

SUBSTANCE: invention relates to dust catchers. The proposed cyclone comprises a casing, gas flow inlet, bin and outlet pipe with its lower part furnished with orifices and its upper part accommodating, at least, one nozzle to form a fine spray cone. The acoustic nozzle comprises a casing to house an acoustic oscillation generator representing a nozzle and resonator made up of concentric annular slots arranged in the plane perpendicular to the casing axis. It incorporates also a taper surface ring, a sprayer fixed in the casing by a hollow rod with a screw-type swirler on its end to form a spray cone and a flange to accommodate an annular site. The resonator is furnished with, at least, one spherical space arranged in the ring wall. The said spherical space communicates, via metered orifice, with the said annular slot formed by end face surfaces of the casing and the ring, on the side of taper surface. Aforesaid ring is arranged to move along the casing axis with the help of a threaded joint.

EFFECT: higher efficiency and reliability of dust separation due increased rate of fluid spraying by nozzles.
