The invention relates to the atomization of liquids, solutions.

The closest technical solution to the declared object is the nozzle on the patent of Russian Federation №2422724, F02C 7/24, comprising a housing with a chamber turbulence and nozzle liner (prototype).

A disadvantage of the known nozzle is that it does not provide a wide spray.

The technical result - improving the efficiency of atomization by increasing the spray.

This is achieved by the fact that in the vortex nozzle, comprising a housing with a chamber turbulence and the nozzle, the body is made in the form of the inlet fitting with a Central hole, and rigidly connected with it, and a coaxial cylindrical sleeve with internal thread and expansion chamber, coaxially with the casing coaxially this body, in its lower part connected to the sleeve by threading the nozzle is made in the form of an inverted Cup, the bottom of which is made turbulent swirl flow with at least two inclined towards the axis of the nozzle inlets in the form of cylindrical holes located in the end surface of the nozzle, where also made the Central cylindrical throttle opening, connected to the mixing chamber of the nozzle, sequentially connected to the diffuser output chamber and diffuser outlet chamber installed rosekat is l, made in the form of at least three spokes, each of which one end is fixed on the outer surface of the diffuser exit chamber, perpendicular to the forming surface, and the other in a surface of a body of revolution such as a sphere, the axis of which coincides with the axis of the diffuser exit chamber, and the body of rotation is in the lower part for a slice of the diffuser exit chamber.

The drawing shows a diagram of the vortex nozzle.

Vortex nozzle includes a body 1 which is made in the form of inlet fitting with a Central hole 3 and is rigidly connected with him and coaxial cylindrical sleeve 2 with internal thread 5. In the cylinder liner 2 is expansion chamber 4, coaxially to the housing.

In the end surface of the nozzle 6 is also made of the Central cylindrical throttle hole 8, connected to the mixing chamber 11 of the nozzle, sequentially connected to the diffuser output of the camera 2. Moreover, the effective area of flow sections inclined cylindrical holes 9 and 10, taken together, and the Central holes 8 are equal.

Vortex nozzle operates as follows.

The sprayed liquid enters the housing 1 through the Central hole 3, then in the expansion chamber 4, coaxially to the housing 1. After the chamber 4, the fluid is directed to the nozzle 6, which is distributed in several directions: first in the Central cylindrical throttle hole 8 in the mixing chamber 11, and the second in turbulent swirl flow with oblique to the axis of the nozzle inlets in the form of cylindrical holes 9 and 10. also connected to the mixing chamber 11 of the nozzle, where the interaction of these common thread is their split with the formation of turbulent flow heading to the diffuser output of the camera is 12, where additional fragmentation of liquid droplets when they collide with each other due to the expanding turbulent fluid flow.

The output of the diffuser chamber 12 is a collision in the output of a vortex flow divider, its spokes 13 and the surface of the body of rotation 14, which leads to additional fragmentation of liquid droplets, the formation of mist jets.

Vortex nozzle, comprising a housing with a chamber turbulence and the nozzle, the body is made in the form of the inlet fitting with a Central hole and rigidly connected with it, and a coaxial cylindrical sleeve with internal thread and expansion chamber, coaxially with the casing coaxially this body, in its lower part connected to the sleeve by threading the nozzle is made in the form of an inverted Cup, the bottom of which is made turbulent swirl flow with at least two inclined towards the axis of the nozzle inlets in the form of cylindrical holes located in the end surface of the nozzle, which also made the Central cylindrical throttle opening, connected to the mixing chamber of the nozzle, sequentially connected to the diffuser output chamber, characterized in that the diffuser outlet chamber has a divider, made in the form of at least three spokes, each of to whom that one end fixed on the outer surface of the diffuser exit chamber, perpendicular to the forming surface, and the other in a surface of a body of revolution such as a sphere, the axis of which coincides with the axis of the diffuser exit chamber, and the body of rotation is in the lower part for a slice of the diffuser exit chamber.
