Description

one

The invention relates to fire fighting equipment, in particular, to devices for spraying a fire extinguishing liquid in stapionary fire protection systems of closed process equipment.

Fluid spraying devices are known to have a hollow body with concentric centrifugal inserts arranged in it, which are swirl chambers (1).

The disadvantages of such devices are the small angle of atomization of the liquid or its uneven distribution over the cross section of the torch at a higher angle of atomization.

Another liquid spraying device is also known, consisting of a cylindrical hollow body and a hollow insert concentrically disposed therein, the walls of which have through-tangentially located openings and a deflector; located in the outlet of the housing.

However, the angle of atomization of the liquid of such a device is small, and the spray has inside the area unfilled with liquid.

The purpose of the invention is to increase the spray angle and increase the irrigation uniformity.

For this purpose, in a device for spraying a liquid containing a cylindrical hollow body and concentrically placed in

It has a hollow insert, the walls of which have through-tangentially located holes and a deflector located in the outlet, the exhibition has a vortex chamber placed coaxially and sequentially with the cavity of the insert, the walls of the vortex chamber also have through-tangentially located holes that connect it to the body cavity and the output nozzle.

FIG. 1 shows an apparatus for atomizing liquids; on phpg. 2 is a section along A-A in FIG. one; pas figs. 3 is a section along the BB in FIG. one; on fng. 4 - the proposed device, view from the outlet openings.

In the cylindrical hollow body 1 there is a concentric mounted insert 2, the walls of which have through-tangentially located holes 3. The insert has a vortex chamber 4, which is coaxially aligned

consistently with the cavity of the insert, the walls of which also have through-tangentially located holes 5, and a central outlet nozzle 6. In the outlet of the housing 7, place the deflector 8, which

9 slots equally spaced around the circumference.

The device works as follows.

Extinguishing fluid enters the hollow

insert 2, passes through tangentially located holes 3, twists, part

it enters the vortex chamber 4 through the tangential holes 5 located in the direction of rotation of the flow, and flows through the central outlet nozzle 6, and the other part of the fluid flows through the outlet of the housing 7 and the slots 9 of the deflector 8. Due to the different outflow rates of the liquid through the central outlet the nozzle, the outlet of the housing and the deflector are uniform distribution of the liquid over the cross section of the torch. This achieves the main effect of extinguishing a fire in closed process equipment.
