ACOUSTIC NOZZLE Russian patent published in 2008 - IPC F23D11/34 

FIELD: engines and pumps.

SUBSTANCE: invention is related to facilities for spraying of liquids, solutions, and may be used in propulsion engineering, chemical, food and light industries. Acoustic nozzle contains casing with generator of acoustic oscillations installed in it in the form of nozzle and resonator, tubes for supply of air and liquid. Casing is arranged in the form of vertically installed cylindrical sleeve, in top part of which tube is installed for air supply, and tube for liquid supply is installed perpendicular to its axis, at that inside casing, coaxially to it, sleeve is rigidly fixed with top and bottom flanges, at that bottom flange is rigidly fixed in the groove arranged in casing, and inside the sleeve, coaxially to it, annular volume resonator is installed, arranged in the form of cup with tapered surface, cup is pressed on the rod with diameter d of resonator, and in its tailpiece fixing disks are installed that are arranged in the form of elastic petals that interact with internal surface of sleeve, and in the bottom flange at least one nozzle is provided at the angle to resonator axis, value of which lies within the following range of values: 20°÷40°, at that continuation of nozzle axis lies on circumference that is located in the middle part of tapered surface of resonator.

EFFECT: higher efficiency of spraying.
