Abstract

The invention relates to protective devices for people and equipment against heat radiation and can be used to effectively extinguish fires with a high surface flux density. The goal is to increase the dispersion of the spray. For this, the hydropercussion nebulizer contains an inner perforated cylinder and an outer perforated cylinder enclosing it with a gap, mounted rotatably and formed with evenly spaced tangential orifices. In addition, the nebulizer is provided with pairs of reverse polarity coaxially mounted on cylinders with a gap. The central angles of the sectors between the axes of the holes and the magnets on the inner and outer cylinders are equal. An outer cylinder is installed in the spray gun after shutting off the liquid supply to the inner cylinder when the cylinder bores coincide. This eliminates the possibility of blocking the holes after cessation of the water supply. 3 il.

Description

The invention relates to the protection devices of people, as well as technology from the action of thermal radiation, and is intended to effectively extinguish fires with a high surface density of the radiation flux and to ensure favorable working conditions.

The aim of the invention is to increase the dispersion of the spray.

FIG. 1 shows a hydropercussion sprayer, a general view; in fig. 2 - the same, top view; FIG. 3 is a section A-A in FIG. one.

The hydraulic impact sprayer contains an inner perforated cylinder 1 with openings 2 and an outer perforated cylinder 3 that surrounds it with a gap, mounted rotatably and made with evenly spaced tangential openings k, the center angles of the sectors of which the inner circumference of the circular ring is equal to the center corners of the outer hole sectors circumference of a circular inner cylinder.

In addition, the nebulizer is provided with pipeline 5 and coaxially mounted on cylinders 1 and 3 with a gap of pairs of magnets 6 (for example, four pairs) of reverse polarity.

on the inner and outer cylinders 1 and 3 are equal to each other (cp h n)

The upper parts of the cylinder 1 and the pipeline 5 are made with a diameter equal to the outer diameter of the cylinder 3, which keeps the cylinder from axial displacements.

Hydraulic spray liquid works as follows.

The pressurized fluid is supplied through conduit 5 into the stationary cylinder 1, passes through the openings 2 in it and enters the openings k of the cylinder 3. When fluid flows out of the openings k of the outer cylinder 3, which are made tangentially, a reactive moment occurs when it exceeds the moment The forces of attraction of magnets 6, cylinder 3 comes into rotational motion, the Segner wheel effect is adjusted.

Since the openings 2 of the stationary cylinder 1 periodically overlap with the walls of cylinder 3, the flow area of the fluid varies from maximum value to zero. The fluid flow rate also varies periodically from maximum value to zero. The phenomenon of full water hammer occurs, as a result of which the fluid pressure rises sharply. This leads to an increase in the flow rate of the fluid when opening the holes, an increase in the kinetic energy of the fluid, and consequently, an increase in the reactive moment, which increases the frequency of rotation of the cylinder 3. The pressure pulsations additionally turbulize the fluid. Uve

The frequency of rotation causes the rotary cylinder 3 to break the flowing fluid into smaller portions. These processes result in a finely dispersed phase close to aerosols.

When the supply of fluid is stopped by the action of the moment of mutual attraction forces of opposite pole magnets 6 coaxially mounted in the tops of cylinders 1 and 3, the rotating cylinder stops in the position of alignment of the openings 2 and A.

The hydraulic impact sprayer is ready for use again.

The form * l of the invention is increased by the moment of attraction of magnets 6, cylinder 3 comes into rotational motion, the effect of the Setner wheel is regulated. Since the holes 2 of the stationary cylinder 1 periodically overlap the walls of the cylinder 3, the area A hydropercussion liquid atomizer comprising an inner perforated cylinder and a loaded perforated cylinder that is rotatably mounted and configured from a uniformly extending fluid section and surrounds it with a gap and changes from a maximum cross section of the fluid, changes from a maximum value to zero. The fluid flow rate also periodically changes from a maximum value to zero. There is a phenomenon of complete water hammer, as a result of which the liquid pressure rises sharply. This leads to an increase in the rate of fluid outflow when opening the holes., An increase in the kinetic energy of the liquid, and the investigator by the tangential holes, the central angles of the sectors of which are the inner circumference, the circular ring are equal to the central angles of the sectors of the holes of the outer circumference of the circular ring of the inner cylinder, characterized in that, in order to increase the dispersion of the spray, it is equipped with pairs of magnets of reverse polarity coaxially mounted on the cylinders with a gap, moreover, it is valuable to increase th reactive moment, which increases the frequency of rotation of the cylinder 3. Pressure pulsations additionally turbulize the liquid. The angles of sectors between the axes of the holes and magnets on the inner and outer cylinders are equal to each other.
