A disadvantage of the known acoustic nozzle is that it does not provide a high degree of dispersion.

The technical result - improving the efficiency of spray.

This is achieved by the centrifugal atomizer with active dispenser, comprising a housing, in which is inserted the screw and the socket for the supply of fluid, the housing consists of two coaxially interconnected, cylindrical sleeves: sleeves of larger diameter and a sleeve of smaller diameter and the inside sleeve of smaller diameter, coaxially to it, is screw rigidly connected with its inner surface, for example pressed therein, and the outer surface of the screw is a screw groove, and the inside of the auger made a hole with a screw thread, and the sleeve has a larger diameter coaxial she is fitting rigidly mounted in n the th, for example, by threaded connection, through a sealing gasket within the fitting is cylindrical coaxial bore passing into asymmetrically located diffuser, which is connected with the cylindrical chamber formed by the inner surface of the sleeve of smaller diameter, and the end surface of the screw, and the end surface of the sleeve of smaller diameter is attached, at least two inclined spaced rod, each of which is assigned an active nozzles, for example, made in the form of blades, resting at the bottom lugs mounted on the rods, perpendicular to their axes, and the rods are tilted away from the axis of the nozzle, i.e. the on the conical surface, the apex of which is directed toward the sleeve of larger diameter.

The drawing shows a General view of the centrifugal atomizer with active spray.

Centrifugal atomizer with active dispenser consists of a casing consisting of two coaxially interconnected, cylindrical bushings: bushings 5 of larger diameter and the sleeve 4 of smaller diameter. Inside the sleeve 4 of smaller diameter, coaxially to it, is screw 1, is rigidly connected with its inner surface, for example pressed into her. The outer surface of the auger 1 is a helical groove on the right (or left) cuts. PR is between the inner surface of the sleeve 4 of smaller diameter and the outer surface of the screw 1 is formed by a helical external cavity 3 of the screw 1.

Inside of the screw 1 has a hole 2 on the left (or right) screw cutting.

When the direction of screw thread hole 2 made inside of the screw 1 may be opposite to the direction of the external helical grooves of the screw.

In the sleeve 5 has a larger diameter coaxial she is fitting 7, rigidly fixed therein, for example by threaded connection, through a sealing gasket 6. Inside the fitting 7 is cylindrical coaxial hole 8 passing in asymmetrically located cone 9, which is connected with the cylindrical chamber 10 formed by the inner surface of the sleeve 4 of smaller diameter, and the end surface of the screw 1.

The end surface of the sleeve 4 of smaller diameter is attached, at least two inclined spaced rod 11, on each of which is assigned an active nozzles 12, for example made in the form of blades, resting at the bottom of the lugs 13, secured to the rods 11, perpendicular to their axes, and the rods are tilted away from the axis of the nozzle, i.e. the conical surface, the apex of which is directed toward the sleeve 5 of larger diameter.

Centrifugal atomizer with active atomizer for atomization of liquids is as follows.

Liquid is supplied along the cylindrical hole 8 of the nozzle 7 into the diffuser 9, and is it in the camera 10, of which is supplied under pressure simultaneously in two directions: first, screw in the external cavity of the screw 1, forming the outer rotating fluid flow, and secondly, in the hole 2 with the screw cutting, forming an internal rotating fluid flow.

At the exit of the nozzle there are two rotating fluid stream, one stream, for example an internal, makes rotation in the direction opposite to the external flow along the screw 1, or may perform associated (same) rotation if the direction of the helical grooves is the same. When interacting rotating flows at the exit of the nozzle is further fragmentation of liquid droplets due to their collision in passing or counter-rotating liquid flows (internal and external). While the total fine rotating flow at the outlet may have a direction of rotation, which is determined by the hydraulic resistance of the external or internal helical cavity and grooves of the screw 1, and may be stationary, in the case of the opposite direction of rotation flows, and equity in their present mass velocities. Screw 1 nozzle can be made of solid materials: tungsten carbide, ruby, sapphire.

Additional fragmentation of liquid droplets occurs due to the inclined arrangement is different rods 11, each of which is assigned an active nozzles 12, for example made in the form of blades, resting at the bottom of the lugs 13 secured on the rods 11.

At an average pressure supplied through the cylindrical hole 8 fluid under pressure 6...9 MPa is sprayed from 400 to 1000 kg/h of liquid. The nozzle is easy to manufacture and maintain.
