CENTRIFUGAL VORTEX NOZZLE Russian patent published in 2018 - IPC B05B1/26 

FIELD: devices for burning fuel; methods of burning fuel.

SUBSTANCE: invention relates to means for dispersion of liquids, solutions. Centrifugal vortex nozzle comprises a body made in the form of a supply fitting with an opening for supplying liquid from the main line and coaxially connected to it by a cylindrical sleeve with an external thread, the nozzle in the form of a centrifugal swirler of the liquid flow designed in the form of a blind cylindrical insert with at least three tangential insertions as cylindrical holes is connected coaxial with the body located in its lower part by means of a sleeve with an internal thread, wherein the sleeve is part of the nozzle and is installed coaxially with the centrifugal swirler, and a conical aperture is formed in the end face of the centrifugal swirler, which is coaxial with the blind cylindrical insert of the swirler, which is installed in the cylindrical chamber of the body to form an annular cylindrical chamber for supplying liquid to the tangential inlet holes of the centrifugal swirler, the tangential inlet holes being in the form of channels tangential to the inner surface of the blind cylindrical insert and an intensifier of the fluid flow swirl is installed in the centrifugal swirler which is made in the form of a rod, one end of which is fixed to the blind circular surface of the swirler cylindrical insert by means of a screw, and at the other end of which a second flow swirler is mounted, made in the form of a sleeve with a screw external thread with a large pitch of the trapezoidal profile and fixed by means of an internal thread on a rod with a conical shaped fairing coaxial to the nozzle body, a confuser is rigidly attached to the nozzle body cut at the bottom, having a screw thread with a large pitch of the trapezoidal profile on the inner surface, and having a direction opposite to the fluid flow swirl intensifier. Coaxial to the fluid flow swirl intensifier, with a conical shaped cone, a conical flow divider is rigidly attached to the confusor, the upper perforated portion of the flow divider cone entering the confuser surface made with perforation, and the apex of the perforated part of the divider cone is in contact with the apex of the fairing cone, and an additional divider is arranged inside the conical fluid flow divider, which is axially symmetric and coaxially fixed by its upper part to the fairing of the swirl intensifier, and in the lower part of the rod a horizontally disposed bumper circular plate is fixed located at the cutoff level of the outlet opening of the conical flow divider.

EFFECT: technical result is an increase in spray efficiency by increasing the spray pattern.
