KOCHETOV ACOUSTIC NOZZLE Russian patent published in 2018 - IPC A62C31/02 

FIELD: technological processes.

SUBSTANCE: invention relates to spraying of fluids equipment and can be used in fire fighting, agriculture, chemical industry and heat power engineering. This is achieved by the fact that in an acoustic nozzle for spraying liquids containing a hollow housing with a nozzle and a central core, housing is made with fluid supply channel and contains coaxial, rigidly coupled with it bushing with nozzle secured at its lower part, made in form of cylindrical two-stage bushing, which upper cylindrical stage is connected with central cylindrical core by means of threaded connection to, coaxial with it, a central core having a central hole and installed with annular gap relative to cylindrical bushing inner surface, wherein the annular gap is connected to at least three radial channels formed in a two-stage bushing connecting it to an annular cavity formed by the inner surface of the bushing and the outer surface of the upper cylindrical step, wherein annular cavity is connected with housing fluid supply channel, to the central core, in its lower part, a diffuser is rigidly connected, made in the form of flattened cone coaxial with the central hole of the core, and attached by its upper base to the base of the cylinder of the central core, and to truncated cone lower base by means of at least three spokes divider is attached, which is made in form of round end plate, which edges are bent towards the annular gap, and on the truncated cone outer side surface there are screw grooves.

EFFECT: high efficiency of liquid atomizing.
