Abstract

FIELD: process engineering.
SUBSTANCE: hollow cylindrical sprayer casing consist of cylindrical section with outer thread for connection to fluid feed distribution pipeline union and inner thread jointing casing to sprayer taper nozzle so that casing and nozzle form two aligned inner chambers, first intended for fluid feed and second making pressure chamber to produce increased pressure. Jet made up of cylindrical throttle orifice and taper threaded orifice with tape directed toward fluid outlet. Nozzle tape side surface has at least two lines of cylindrical throttling orifices with their axes perpendicular to nozzle side surface. Every line has at least three cylindrical throttling orifices. Note that, in horizontal plane orifice axis projections are spaced apart for angle of 7.5 - 60°. Swirler is arranged inside cylindrical chamber and aligned therewith, made up of outer larger-pitch trapezoidal-shape thread sleeve threaded onto rod secured via mesh filter to casing.
EFFECT: higher efficiency of 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 sprinkler according to patent RU No. 2111033, A62C 31/02, publ. 05/20/98, 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.

This is achieved by the fact that in the nozzle containing the hollow cylindrical body connected to the nozzle in which the holes are made, the body consists of a cylindrical part with an external thread for connecting to the nozzle of the distribution pipe for supplying liquid and an internal thread for connecting with a conical nozzle 5, with the housing and the nozzle form two coaxial inner chambers, the cylindrical chamber serving to supply fluid, and the conical chamber formed by the surface of the truncated cone of the nozzle being a pressure chamber to create increased pressure, and a nozzle is made on the nozzle from the side opposite to the fluid supply, which consists of a cylindrical throttle hole and a conical hole with expansion towards the object, while on the surface of the conical hole a screw thread is made to create a fan-shaped liquid exit from the nozzle, and on the conical side surface of the nozzle, at least two rows of cylindrical throttle holes are made, the axes of which are perpendicular to the conical side of the nozzle surface, and in each row at least three cylindrical throttle openings are made, and in the horizontal plane of the projection of the axis of the holes in these rows are separated from each other by an angle of 7.5 ... 60 ° to create a finely divided continuous phase of the sprayed liquid, this in a cylindrical chamber, coaxial to it, is installed with a gap relative to the inner side surface of the chamber, a swirl 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 a enney thread on the rod which is secured at its upper part through a strainer to the housing.

The drawing shows a nozzle diagram.

The nozzle contains a hollow body, consisting of a cylindrical part 1 with an external thread for connecting to the nozzle of the distribution pipe for supplying fluid and an internal thread for connecting with a conical nozzle 5.

The housing 1 and the nozzle 5 form two inner coaxial chambers 4 and 13. The cylindrical chamber 4 serves to supply fluid, and the conical chamber 13, formed by the surface of the truncated cone of the nozzle, is an injection chamber to create increased pressure.

On the nozzle 5 from the side opposite to the fluid supply, a nozzle is made, which consists of a cylindrical throttle hole 8 and a conical hole 9 with an extension towards the object. At the same time, on the surface of the conical hole 9, screw (not shown in the drawing) cutting (for example, a tapered thread with a large pitch) is made to create a fan-shaped liquid exit from the nozzle.

At least two rows of cylindrical throttle holes 6 and 7 are made on the conical side surface 5 of the nozzle, the axes of which are perpendicular to the conical side surface of the nozzle 5, and at least three cylindrical throttle holes are made in each row, and in the horizontal plane of the projection the axes of holes 6 and 7 in these rows are separated from each other by an angle of 7.5 ... 60 ° to create a finely divided continuous phase of the sprayed liquid.

To create the greatest effect of the formation of a finely divided continuous phase of the sprayed liquid in the cylindrical chamber 4, coaxially mounted with a gap 12 relative to the inner side surface of the chamber 4, a swirler 3, made in the form of a sleeve with a screw external thread with a large pitch of a trapezoidal profile and fixed by an internal thread 11 on the rod 2. The rod 2 is fixed in its upper part by means of a strainer 10 to the housing 1.

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, chambers 4 and 13 create swirling fluid flows in chambers 3 and 3, which flow into the nozzle 5, and in the cylindrical throttle openings 6 and 7, fluid flows rushing to the output sections of the holes and the nozzle.

In the collision of expanding fluid flows flowing out through the conical outlet of the screw jet and cylindrical throttle holes 6 and 7, a fan-shaped gas-liquid stream in the form of a shroud is formed, i.e. a liquid droplet crushing mechanism is implemented, but the generated swell-like flow deviates from the horizontal plane by a larger angle, in the range from 45 to 60 °, in the direction of the central region of the irrigated surface located directly under the nozzle.

The proposed nozzle design can be used as a fine spray gun in fire fighting equipment, for example, as part of sprinkler or deluge fire extinguishing systems, in agriculture - for spraying various types of substances on sown areas and in industrial premises, as well as in chemical technology and heat energy devices - for fuel spraying, as well as in industries where the generation of atomized finely dispersed fluid flows is required in both closed and open spaces.
