NOZZLE FOR WET DUST COLLECTING APPARATUS 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. Nozzle for wet dust collecting apparatus comprises a cylindrical chamber for supplying gas, an axial sprinkler with throttling openings for supplying liquid and a swirler of gas-liquid flow, the 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 indentations are made in the form of a spiral of Archimedes, the projections on one disc enter with a gap in the valleys on the other disk with the formation of a channel in the form of a spiral of Archimedes communicating with the cavity of the cylindrical chamber, and in the end part of the cylindrical chamber, at the inlet of gas and liquid flows, a disk with perforation for the gas inlet is located, which is rigidly connected to the cylindrical chamber by its external surface, and the internal surface is rigidly connected to the sprinkler, and two swirlers are successively installed in the cylindrical chamber, while the swirler located at the inlet of the gas flow is rigidly fixed to the sprinkler tube, and the swirler at the outlet is rigidly fastened to the inner surface of the cylindrical chamber, with two gaps between the swirlers for interaction with the gas and the liquid: axial play – for interaction with the liquid and tangential gap – for interaction with the gas, and a diffuser is attached to the end portion of the cylindrical chamber at the outlet of the gas and liquid flows to increase the spray of the gas-liquid flow.

EFFECT: increased efficiency of formation of a finely dispersed gas-liquid phase.
