ATOMIZER WITH PARABOLIC SWIRLER Russian patent published in 2018 - IPC B05B1/34 

FIELD: devices for the liquids spraying or atomizing.

SUBSTANCE: invention relates to devices for spraying liquids for wet cleaning of gas emissions and can be used in the chemical, oil and other industries. Atomizer with a parabolic swirler contains a cylindrical chamber for supplying gas, an axial sprinkler with throttling openings for supplying liquid and a gas-liquid flow swirler. Sprinkler with throttling holes is plugged from the outlet end by a centrifugal element consisting of serially connected profiled disks, on the end part of which protrusions and depressions are made in the form of an Archimedean spiral. Protrusions on one disc enter with a gap in the depressions on another disk with the formation of a channel in the form of Archimedean spiral communicating with the cavity of the cylindrical chamber. In the end part of the cylindrical chamber, at the gas and liquid inlet there is a disk with a gas inlet perforation, which by its external surface is rigidly connected to the cylindrical chamber, and by the inner surface is rigidly connected to the sprinkler. In the cylindrical chamber, two swirlers are installed in series. Swirler, located at the gas inlet, is rigidly fixed to the tube of the sprinkler. Swirler at the outlet is rigidly fixed to the inner surface of the cylindrical chamber. Between the swirlers two gaps are made for communicating with gas and liquid: axial gap for communicating with the liquid and tangential gap – for communicating with the gas. Each of the swirlers is parabolic having the form of an elliptical paraboloid, the guide blades of which are curved.

EFFECT: technical result of the invention is an increase in the efficiency of formation of a finely dispersed gas-liquid phase.
