NOZZLE WITH PARABOLIC SWIRLER Russian patent published in 2017 - IPC B05B1/34 B05B7/00 B01F3/04 B01F5/02 

FIELD: machine engineering.

SUBSTANCE: nozzle comprises a cylindrical chamber 1 for supplying gas, an axial sprinkler 3 with throttle holes 6 for supplying liquid and a swirler 7 of gas-liquid flow. The sprinkler 3 with throttle holes 6 is blanked off from the outlet end by a centrifugal element 9, consisting of successively joined profiled disks 10 and 11, on the end part of which there are projections and recesses in the form of Archimedes' spiral. The projections on one disk 10 enter with a gap the recesses on the other disk 11 to form a channel in the form of Archimedes' spiral, which communicates with the cavity of the cylindrical chamber 1, in the end part of which there is a disk 4 with a perforation 5 for gas inlet, which is rigidly connected with its outer surface to cylindrical chamber 1, and with its inner surface to the sprinkler 3. Two swirlers 7 and 8 are mounted successively in the cylindrical chamber 1. The swirler 7 placed at the inlet of the gas flow, is rigidly fixed to the tube 2 of the sprinkler 3. The swirler 8 at the outlet is rigidly fixed to the inner surface of the cylindrical chamber 1. Between swirlers 10 and 11, there are clearances for interaction with gas and liquid: a tangential clearance 13 and an axial clearance 12. Each swirler 7 and 8 is made in form of elliptical paraboloid, the guide blades of which are bent along the helical surface and form curved confuser channels.

EFFECT: invention makes it possible to increase efficiency of finely dispersed gas-liquid phase formation.
