Description

The invention relates to means for spraying liquids and solutions and can be used in engine building, chemical and food industries.

The closest technical solution to the claimed object is the nozzle according to the patent of the Russian Federation No. 2509262, F02C 7/24, containing a housing with a chamber, into which the screw is pressed in, and a throttle hole is made in the bottom of the housing, and a fitting with a cylindrical hole, a diffuser and gasket (prototype).

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

EFFECT: increased efficiency of liquid spraying.

This is achieved by the fact that in an acoustic vortex nozzle containing a housing and elements for supplying liquid and air, the housing consists of two coaxial, interconnected cylindrical bushings: a larger diameter sleeve and a smaller diameter sleeve, while inside the smaller diameter sleeve, coaxial with it, a screw is located, rigidly connected with its inner surface, the outer surface of the screw being a helical groove forming a screw outer cavity with the inner surface of the sleeve of a smaller diameter, and inside the screw a hole with a screw thread is connected, connected to a tube for supplying liquid under pressure, and a shaped sleeve is located coaxially in a larger diameter sleeve, the inner surface of which is formed by conical and cylindrical surfaces and which is rigidly fixed in the larger diameter sleeve through a sealing gasket having at least one throttle hole and forming with the end surface of the screw and the inner surface of the sleeve of a smaller diameter cylindrical chamber, which through connected to a source of compressed air, and in the cylindrical cavity of the shaped sleeve there is a free end of the fluid supply tube, placed in a coaxial elastic ring, which forms a conical resonance chamber with a sealing gasket, while the throttle hole serves as the neck of the Helmholtz resonator to the end part bushings with a smaller diameter of the body, a diffuser is attached, at the cut of which a liquid flow divider is installed, made in the form of a perforated ring coaxial with the diffuser rum.

The drawing shows a General view of the nozzle for spraying liquids.

An acoustic vortex nozzle consists of a housing consisting of two coaxial, interconnected, cylindrical bushings: bushings 5 of a larger diameter and bushings 4 of a smaller diameter. Inside the sleeve 4 of a smaller diameter, coaxial to it, is a screw 1, rigidly connected to its inner surface, for example, pressed into it. The outer surface of the screw 1 is a helical groove with a right (or left) thread. Moreover, between the inner surface of the sleeve 4 of smaller diameter and the outer surface of the screw 1, an external screw cavity 3 is formed. Inside the screw 1, a hole 2 is made with a left (or right) screw thread connected to the tube 9 for supplying liquid under pressure.

In this case, the direction of the screw thread of the hole 2 made inside the screw 1 can be opposite to the direction of the external screw groove of the screw.

In the sleeve 5 of a larger diameter, coaxial to it, there is a shaped sleeve 7, the inner surface of which is formed by conical and cylindrical surfaces and which is rigidly fixed in the sleeve 5 of a larger diameter, for example by means of a threaded connection, through a sealing gasket 6 having at least one throttle the hole 14 and forming with the end surface of the screw 1 and the inner surface of the sleeve 4 of a smaller diameter, a cylindrical chamber 10, which through the channel 12 is connected to a source of compressed air, n For example, from a compressor (not shown in the drawing).

In the cylindrical cavity of the shaped sleeve 7 there is a free end of the fluid supply pipe 9, placed in a coaxial elastic ring 8, which with a sealing gasket 6 forms a conical resonance chamber 13, while the throttle hole 14 serves as the neck of the Helmholtz resonator. In the end surface of the shaped sleeve 7 there are blind holes 11 for the key.

A diffuser 15 is attached to the end part of the sleeve 4 of a smaller diameter of the housing, on the slice of which a liquid flow divider 16 is installed, made in the form of a perforated ring coaxial with the diffuser 15.

Acoustic vortex nozzle for spraying liquids works as follows.

The liquid is supplied through a cylindrical hole of the tube 9 into the screw-cut hole 2, forming an internal rotating fluid flow, and compressed air is supplied through the channel into the cylindrical chamber 10, and from it into the screw external cavity 3, forming an external rotating air flow.

At the exit of the nozzle, there are two rotating streams, with one stream, the internal one of the liquid, which rotates in the direction opposite to the external air stream. In the interaction of rotating flows at the outlet of the nozzle, additional droplets of liquid are crushed due to their collision in the associated or opposite rotating flows of liquid and air (external and internal). In this case, the total finely divided rotating stream at the outlet may have a direction of rotation, which is determined by the hydraulic resistance of the external or internal screw cavities, respectively, and may be stationary, in the case of the opposite direction of rotation of the flows and the equality of their reduced mass velocities. In this case, the conical resonance chamber 13 with the neck 14 of the Helmholtz resonator enhances the effect of crushing liquid droplets due to the application of acoustic vibrations, the resonant frequency of which is determined by the dimensions of the resonance chamber 13 and the neck 14 of the Helmholtz resonator, as well as by the pressure of the air entering the resonant chamber 13 .

The nozzle screw 1 can be made of solid materials: tungsten carbide, ruby, sapphire. At an average pressure of the liquid supplied through a cylindrical hole in the tube 9 under a pressure of 6 ... 9 MPa, atomization of 400 to 1000 kg / h of liquid is ensured. The nozzle is easy to manufacture and maintain.
