The invention relates to devices for mechanical multi-spraying of liquids and can be used in power engineering, metallurgical, petrochemical, searching and in many other industries, as well as in agriculture, air-conditioning and water conditioning technology.

The aim of the invention is to simplify the construction and expand the scope of application.

Fig. 1 shows the proposed device, general view, longitudinal section; in fig. 2 is a cross-sectional section L-A in FIG. one; in fig. 3 is a cross-sectional view of BB in FIG. 1; FIG. 4 - a device equipped with reflective discs and bushings with locking cuffs, general view, longitudinal section.

A device for multi-fluid spraying of liquids contains a nozzle 1 connected at one end with a source of liquid supply in the form of a pipeline 2, and spray nozzles of counter-impact action, which are made in the side wall of the nozzle 1 in the form of pass-through channels opposite to one another and inclined to the axis of the nozzle 1 3 and 4, the angle between the separations of which is chosen to be from 30 to 150 °.

The bisector of the angle between the axes of each pair of oppositely directed channels 3 and 4 is inclined to the axis of the nozzle 1 at an angle chosen from 45 to 135 °.

Channels 3 and 4 can be made cylindrical, tapered or slotted profile and inclined at an angle of up to 60 ° relative to the axis of the nozzle 1.

On the outer surface of the pipe 1 on both sides of the channels 3 and 4 are mounted reflective disks 5.

On the pipeline 2 of the fluid supply pins 6 are fixed, and at the end of the nozzle 1 there are response G-o different grooves 7 and an elastic sealing ring 8 is installed.

When a long-length pipe 1 is made of a non-corrosive material, such as iron, or an elastic one, such as a rubber or polyethylene hose, the sleeves 9 of a corrosion-resistant material, such as caprone, are fixed in channels 3 and 4.

or fluoroplastic, with the help of the fixing cuff 10.

The multi fluid spraying device works as follows.

Under pressure from 0.6 kgf / cm and more through the pipeline 2, the fluid with a speed of up to 1 m / s enters the nozzle 1 and spreads it through the channels

10 3 and 4, where, as a result of a reduction in the flow area, the velocity of the fluid flows increases to 6 m / s and more. The oppositely directed jets of liquid at an angle of from 30 to 150 so15 strike each other over the outer surface of the nozzle 1 and each pair of jets forms a flat torch in free space. All torches collectively form around

20 nozzle 1 is a multi-colored crown of drops; The number of Rus (zones) depends on the number of pairs of channels 3 and 4, located along one line. The form of a lot of blond crown itself is different and depends

25 from the location of channels 3 and 4 along the side surface of the nozzle 1.

With an increase in the angle between the colliding liquid streams (other things being equal) the average

30, the size of the droplets formed and their range are reduced, and the starting angle of the flare and the irrigation density increase. In cases where individual mechanical particles with a size larger than the flow area of channels 3 and 4 are allowed to enter the liquid, it is necessary to equip the device with reflective disks so as to allow shock spraying of liquid from non-clogged channels. For the specified operating conditions in the device, it is most expedient to carry out channels 3 and 4 of cylindrical profi l. In order to ensure long-range torch droplets, channels 3 and 4 it is advisable to perform a cone-shaped profile, and in order to achieve a high irrigation density,

5Q prominent profile.

The recommended bore area of channels 3 and 4 is 2-100 mm. If it is necessary to irrigate large areas, for example, a farm in a farm, in sewage treatment plants, mines, and quarries, pipelines of the required length are provided as pipe 1.

metal or elastic materials, for example polyethylene or rubber, and in them radial channels 3 and 4. In channels 3 and 4, using sleeves 10, sleeves 9 are mounted, and if necessary, reflective disks 5.

The invention provides low labor intensity for manufacturing from non-deficient, inexpensive materials, the ability to perform with a single

 capacity from 2-3 to 20-30 t / h and more, a multi-colored structure of the generated torch droplets, covering a large area and volume; low energy consumption both for the dispersion of the liquid and for its dispersion in the surrounding space; ease of operation due to the equipment with a quick-release docking station and a fixed zipper cuff.

Claims (1)

1. DEVICE FOR MULTI-TIRE SPRAYING OF LIQUIDS, containing a nozzle connected at one end to a source of fluid supply, and spray nozzles. counter-shock action, differs by the fact that, in order to simplify the construction and expansion of the scope of application, spray nozzle counter-shock action made in the side wall of the nozzle in the form of through pairwise oppositely directed inclined to the channel and the nozzle axis, the angle between the axes _{of the} which is selected equal to from 30 to 150 2. The device according to claim 1, characterized in that the bisector of the angle between the axes of each pair of opposing channels is inclined to the axis of the pipe at an angle selected from 45 to 135.
