Abstract

FIELD: machine building.
SUBSTANCE: atomiser contains a hollow cylindrical casing with vortex flow divider, in top part of the casing external thread is made for connection to union of the distribution pipeline for liquid supply. In bottom part of the casing external thread is made for connection with cone divider of the vortex flow by means of retainer. The retainer is made in form of ring, to which the external and internal perforated surfaces are secured. Casing has internal cylindrical chamber with installed in it swirler. The swirler is made in form of bushing with external screw trapezoidal thread with large pitch, and it is secured by means of the internal thread on stock. Between the external and internal perforated cone surfaces of the vortex flow divider there are elements increasing resistance against output liquid flow with simultaneous its split.
EFFECT: higher efficiency of fine liquid spraying.

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 nozzle according to patent RU No. 2481137, A62C 31/02, (prototype), containing a hollow cylindrical body with a swirl divider. Using the known design allows you to get a uniform flow volume of fine spray droplets in the range of droplet diameters from 30 to 150 microns at 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 vertical and inclined directions and have an uneven distribution with respect to the horizontal plane at the nozzle exit.

The technical result is an increase in the efficiency of fine atomization of a liquid.

This is achieved by the fact that in the nozzle containing a hollow cylindrical body with a swirl flow divider, an external thread is made in the upper part of the body for connecting to the nozzle of the distribution pipe for supplying fluid, and an external thread is made in the lower part of the body for connection with a swirl conical divider by holders made in the form of a ring to which external and internal perforated surfaces are attached, and in the case there is an internal cylindrical chamber, which it is used to supply fluid, and in which a swirl is installed coaxially and with a gap relative to its inner side surface, made in the form of a sleeve with a screw external thread with a large step of a trapezoidal profile and fixed by means of an internal thread on the rod, which is fixed in its upper part by means of a mesh filter to the housing, between the external and internal perforated conical surfaces of the vortex flow divider, there are elements that increase the resistance to the outgoing fluid flow while crushing it.

The drawing shows a nozzle diagram.

The nozzle comprises a hollow cylindrical body 1, in the upper part of which an external thread is made for connection to a fitting (not shown) of a distribution pipe for supplying liquid, and in the lower part of the body, an external thread is made for connection with a vortex flow conical divider 8 by means of a clip 9, made in the form of a ring to which an external perforated surface 10 and an internal perforated surface 11 are attached. An external perforated surface 10 and an internal perforated surface the surface 11 is made conical and coaxial with the housing 1. In the housing 1 there is an inner cylindrical chamber 4, which serves to supply fluid. To create the greatest effect of the formation of a finely divided continuous phase of the sprayed liquid in the cylindrical chamber 4, a swirler 3 is arranged coaxially with a gap 7 relative to the inner side surface of the chamber 4, made in the form of a sleeve with a screw external thread with a large pitch of a trapezoidal profile and fixed by means of an internal thread 6 on rod 2. The rod 2 is fixed in its upper part by means of a strainer 5 to the housing 1.

Between the outer 10 and the inner 11 of the perforated conical surfaces of the vortex flow divider, there are elements 12 that increase the resistance to the outgoing fluid flow with its simultaneous crushing. In the end part of the swirl 3, facing the vortex flow divider 8, there is a cone shaped fairing 13, which increases the rate of vortex exit from the swirl 3 due to the absence of turbulence of the vortex flow.

The nozzle is as follows.

When the fluid is supplied to the housing 1 under the action of a pressure drop of 0.4 ... 0.8 MPa in the chamber 4, due to the swirl 3, vortex flows of fluid are created, which flow into the conical divider 8, and when the expanding fluid flows expiring through the gap 7 collide with perforated the conical surfaces 10 and 11 of the divider 8 forms a fan-shaped gas-liquid flow in the form of a shroud, i.e. a mechanism for crushing liquid droplets is implemented. Elements 12, located between the outer 10 and inner 11 perforated conical surfaces, increase the resistance to the outgoing fluid flow with its simultaneous crushing, which generally leads to an increase in its finely dispersed spraying.
