FIELD: technological processes.

SUBSTANCE: invention relates to liquids spraying devices for gas emissions wet cleaning and can be used in the chemical and petroleum industries. Nozzle comprises a cylindrical chamber 1 for gas supply, an axial sprinkler 3 with throttling holes 6 for liquid supply and a gas-liquid flow swirler 8. Sprinkler 3 with throttling holes 6 is plugged from the outlet end by a centrifugal member 9 consisting of serially connected profiled disks 10, 11 on the end part of which protrusions and indentations are made in the form of an Archimedes spiral. Protrusions on one disc 10 enter in the indentations on the other disc 11 with a gap, forming a channel in the form of an Archimedes spiral communicating with the cylindrical chamber 1 cavity. In the cylindrical chamber 1 end part, at the gas and liquid flows inlet, a disk 4 with a perforation 5 is located for gas inlet, which is by its external surface rigidly connected to the cylindrical chamber 1, and by the inner surface is rigidly connected to the sprinkler 3. In the cylindrical chamber 1 two swirlers 7, 8 are successively installed. Located at the inlet of the gas flow swirler 7 is rigidly attached to the tube 2 of the sprinkler 3. Located at the outlet swirler 8 is rigidly attached to the cylindrical chamber 1 inner surface. Between the swirlers 7, 8, two gaps are made for interaction with the gas and the liquid: the axial gap 14 is for interaction with the liquid and the tangential gap 15 for interaction with the gas. Each of the swirlers 7, 8 is made in the form of an elliptical paraboloid, the guide blades of which are curved along the helical surface and form curvilinear convergent ducts 16.

EFFECT: invention allows to increase a finely dispersed gas-liquid phase formation efficiency.
