SWIRL ATOMIZER Russian patent published in 2018 - IPC B05B1/00 F23D11/04 

FIELD: instrument engineering.

SUBSTANCE: invention relates to means for dispersion of liquids, solutions. Swirl atomizer contains a body with a swirl chamber and a nozzle. Body is made in the form of a supply fitting with a central hole and rigidly connected to it and a coaxial cylindrical sleeve with an internal thread and an expansion chamber coaxial to the housing. Nozzle made as a inverted barrel is attached to the sleeve by the thread coaxially to the casing in its lower part. Turbulent fluid flow swirl is made in the bottom of the cup with at least two inclinations to the axis of the nozzle in the form of cylindrical holes located in the end surface of the nozzle. Also in the bottom of the glass is a central cylindrical throttle hole connected to the mixing chamber of the nozzle, in series connected to the diffuser outlet chamber. Diffuser is installed in the diffuser outlet chamber, made in the form of at least three spokes, each of which is fixed at one end to the outer surface of the diffuser outlet chamber, perpendicular to the surface forming it, and the other to the surface of the body of revolution. Body of revolution is an ellipsoid whose minor axis is axisymmetric to the axis of the diffuser outlet chamber. To the end surface of a cylindrical sleeve, coaxial with the housing, coaxial to the diffuser chamber, a diffuser is attached, the cutoff surface of which lies in a plane below the surface of the body of the spinner's rotation. In the body of rotation, whose axis coincides with the axis of the diffuser outlet chamber, and the body of revolution itself is located in the lower part behind the cutoff of the diffuser outlet chamber, the notches are shaped in the form of a cylindrical surface of different diameters and lengths, performing the functions of Helmholtz resonators.

EFFECT: invention makes it possible to increase spray efficiency by increasing the spray pattern.
