Abstract

FIELD: machine building.
SUBSTANCE: centrifugal vortex burner containing casing, captive nut, insert with tangential channels tapering along the flow, vortex chamber, nozzle and disk. The insert and disk are made out of metal-ceramics. In end surface of the captive nut a central hole is made axisymmetric to the casing. The insert has tangential channels located in the plane perpendicular to the casing axis. The vortex chamber is connected with the tangential channels. The disk is adjacent to end face of the insert at side of the tangential channels perpendicular to the casing axis. To the end surface of the captive nut a plate sprayer is secured axisymmetric to the casing. The sprayer contains perpendicular to the casing axis and parallel to between each other plates, one plate, i.e. first plate has central hole, and second plate is made solid, and is secured to the first plate by means of the fasteners. The second solid plate of the plate sprayer is made rather convex or concave then plane, at that tip of the convex surface can be directed both towards end face of the captive nut, and from it, and second plate of the plate sprayer is made perforated at area limited by the calibrated inserted washers, installed between plates of the plate sprayer.
EFFECT: reduced hydraulic resistance of the injector upon keeping the flowrate characteristics, assurance of homogeneous degree of mixing with inflowing medium.

Description

The invention relates to techniques for spraying liquids and can be used in fire fighting equipment, in agriculture, in chemical technology devices and in the power system.

The closest technical solution to the claimed object is the sprinkler according to patent RU No. 2485986, А62С 31/02, containing a hollow cylindrical body with a fluid supply pipe, a nozzle and an additional row of throttle openings.

The use of a finely dispersed sprayer of the described design allows one to obtain a uniform volume flow of finely dispersed droplets in the range of droplet diameters from 30 to 150 microns with a water supply pressure of not more than 1 MPa.

However, a sprayer of this design does not allow to achieve a given distribution of flows of fine droplets on the irrigation surface of the required area without increasing the flow rate of the liquid. This is due to the fact that the droplet flows generated by most of the holes are oriented in the horizontal direction and have a symmetrical distribution relative to the horizontal plane at the nozzle exit.

The technical result is an increase in the efficiency of finely dispersed liquid spraying by reducing the hydraulic resistance of the nozzle while maintaining the flow characteristics, ensuring a homogeneous degree of mixing with the inflow medium.

This is achieved by the fact that in a centrifugal vortex nozzle containing a housing, a flare nut, a liner with tangential channels tapering along the flow, a swirl chamber, a nozzle and a disk adjacent to the end face of the liner on the side of the tangential channels, while the liner and disk are made of cermet, the input the edges of the tangential channels are rounded, in the end surface of the union nut, axisymmetrically to the body, a central hole is made up of a cylindrical part and a conical part, and the liner has at least three and a tangential channel located in a plane perpendicular to the axis of the housing, as well as a twisting chamber connected to the tangential channels, a throttle hole coaxial to the housing located at the bottom of the liner, and a disk adjacent to the end of the liner from the side of the tangential channels perpendicular to the axis of the housing, and the end surface of the union nut, axisymmetrically to the body, a lamellar atomizer is mounted, consisting of at least two plates perpendicular to the axis of the body and parallel to each other, one of which On the other hand, the first plate has a central hole, and the second plate is solid and fastened to the first by at least three fasteners, including a screw, and spacing calibrated washers installed between the plates, as well as between the end surface of the union nut and the first plate, while the second, continuous, plate of the plate sprayer is made not flat, but convex or concave, and the apex of the convex surface can be directed aside toward the end surface the nut, and from it, and the second plate of the plate spray gun is made perforated in the area limited by the installation calibrated washers installed between the plates of the spray bottle.

In FIG. 1 shows a frontal section through a centrifugal vortex nozzle; FIG. 2 is a horizontal section through the nozzle of the nozzle.

The centrifugal vortex nozzle consists of a tubular body 1 (Fig. 1), in which, with the help of a union nut 2, a liner 7 is coaxially fixed through the sealing gasket 7. A central hole is made in the end surface of the union nut 2, axisymmetrically to the housing 1, consisting of a cylindrical part 8 and conical part 9.

The insert 7 has at least three tangential channels 3 (Fig. 2 - four channels are shown in the drawing) located in a plane perpendicular to the axis of the housing 1, as well as a twisting chamber 4 connected to the tangential channels 3, a throttle hole coaxial to the housing 1 5, located in the lower part of the insert 7 and the disk 6, adjacent to the end of the insert 7 from the side of the tangential channels perpendicular to the axis of the housing 1. The tangential channels 3 are made with rounded inlet edges and tapering along the flow. The liner 7 and the disk 6 are made of cermet.

A plate sprayer is mounted to the end surface of the union nut 2, axisymmetrically to the housing 1, consisting of at least two plates perpendicular to the axis of the housing and parallel to each other, one of which, the first plate 11, has a central hole 15, and the second plate 12 is made continuous and fastened to the first by means of at least three fasteners 16, including a screw, and calibrated washers 13 and 14 installed between the plates 11 and 12, as well as between the end surface of the union nut 2 the first plate 11, which function as the regulating unit controlling the gap between the plates 11 and 12, the nebulizer affecting the dispersibility of the spray medium.

The second, solid, plate 12 of the plate spray can be made not flat, but convex or concave (not shown in the drawing), and the top of the convex surface can be directed both towards the end surface of the union nut 2 and away from it. It depends on the viscosity of the sprayed liquid and the required degree of dispersion of the sprayed liquid stream.

The second plate 12 of the lamellar diffuser is perforated in the area bounded by the calibrated washers 14 installed between the plates 11 and 12 of the lamellar diffuser.

An elliptical perforated flow divider 18 is attached to the second plate 12 of the plate spray gun by means of at least three spokes 17, the degree of perforation being less than that of the second plate 12 of the plate spray gun.

The centrifugal vortex nozzle works as follows: from tangential channels 3, the liquid jets under pressure enter the swirl chamber 4, from which they are sprayed through the throttle aperture under the action of pressure and centrifugal forces 5. Then, the finely dispersed vortex flow first enters the cylindrical part 8 of the central hole, and then into the conical part 9 of this hole, forming a torch of a finely dispersed vortex flow, the opening angle of which is determined by the angle of the conical part 9 of the central hole. The tangential channels 3 are made with rounded inlet edges and tapering along the flow, which further reduces hydraulic resistance and improves the quality of atomization, and secondary crushing of liquid droplets and obtaining a fine torch provides a plate spray due to the fact that the second plate 12 of the plate spray is perforated bounded by calibrated washers 14 mounted between the plates 11 and 12 of the plate atomizer.
