Abstract

FIELD: machine building.
SUBSTANCE: centrifugal swirl atomiser 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 the 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, and vortex chamber. Throttle hole is located in the bottom part of the insert. The disk is adjacent to end face of the insert at side of the tangential channels perpendicular to the casing axis. To the end face of the captive nut the plate sprayer is secured, it contains plates at right angle to the casing axis and parallel with each other. It has central hole, and second plate is made continuous and is secured to the first by means of the fasteners. Second continuous plate is made perforated and convex towards end face of the captive nut.
EFFECT: higher efficiency of liquid atomising due to reduced hydraulic resistance of the atomiser at keeping the flow characteristics, provision for homogeneous mixing with the inflow 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. 2111033, A62C 31/02, publ. 05/20/98), containing a hollow cylindrical housing with a nozzle for supplying liquid 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 swirl 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 to the end the surface of the union nut, axisymmetrically to the body, a plate atomizer is mounted, consisting of perpendicular to the axis of the body and parallel to each other at least two plates, one of the cat First, the first plate has a central hole, and the second plate is solid and fastened to the first by means of 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, the second continuous plate of the plate spray gun is made perforated and convex towards the end surface of the union nut.

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 a 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 atomizer 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 solid and attached 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 and the first plate 11, which perform the function of the regulatory link, controlling the gap between the plates 11 and 12 of the sprayer, affecting the dispersion of the sprayed medium.

A divider is attached to the second continuous plate 12 of the lamellar atomizer, made in the form of a vertical, axisymmetric nozzle body, a rod 17, to the lower part of which at least three inclined spokes 18 are attached, the impellers 19 are mounted on their free ends facing the atomizer with the possibility of rotation around the axis of the spokes.

The second continuous plate 12 of the plate atomizer is perforated and convex (not shown in the drawing) towards the end surface of the union nut 2.

The degree of perforation depends on the viscosity of the sprayed liquid and the required degree of dispersion of the sprayed liquid stream.

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 the hydraulic resistance and improves the quality of atomization, and the secondary crushing of liquid droplets and obtaining a fine torch provides a plate spray.
