ACOUSTIC NOZZLE Russian patent published in 2009 - IPC F23D11/34 

FIELD: technological processes.

SUBSTANCE: invention is related to facilities for spraying of liquids, solutions. Acoustic nozzle comprises body with acoustic generator installed inside in the form of nozzle and resonator, tube for supply of air and liquid. Body is arranged in the form of cylinder with bottom, body is provided with cylindrical cavity for supply of liquid via tube arranged in cover, in upper part of which fastening element is provided that fixes upper part of gas-jet transmitter rod in nozzle provided in cover, and upper part of rod is hingedly fixed to lower part of transmitter in cover by means of at least one fixing disk arranged in the form of at least three elastic lobes that interact with internal surface of cover tapered surface, and slot channel for liquid supply is arranged between opening in body bottom and external surface of nozzle cover, and annular channel for supply of spraying agent is arranged between internal surface of tapered opening and external surface of rod lower part. Ratio of transmitter height h₁ to distance h between upper base of tapered surface and lower end surface of nozzle lies within optimal range of values: h₁/h=1÷3; ratio of internal diameter d₁ of transmitter cavity to diameter d₂ of its external cylindrical surface lies in optimal range of values: d₁/d₂=0.7÷0.9; ratio of external diameter d₁ of transmitter cavity to diameter d of its rod lies in optimal range of values: d₁/d=1÷3; ratio of internal diameter d₁ of transmitter cavity to cavity height h₁ lies in optimal range of values: d₁/h₁=1÷1.5.

EFFECT: higher efficiency of spraying.
