For example, the patent case RU 2132752 C1 (IPC-6 B05B 7/〇4, published on 1W1_Japanese) describes a portable fire extinguishing device for generating long-distance gas dripping flow. - a liquid atomizer used as a component of such devices comprising - a shaped gas powered nozzle, a liquid and gas mixing chamber, a liquid misting device for atomizing a liquid stream to be supplied to the mixing chamber, And a system for supplying liquids and gases to the mixing chamber. A fire extinguishing liquid is stored in a storage tank of a given device and is forced out of the storage tank by the action of pressurized gas during operation of the apparatus. : A device of the prior art is known to allow high velocity gas droplets to be ejected up to a distance of up to 12 m. However, it should be borne in mind that a gas-powered procedure for accelerating liquid droplets in a gas stream limits the angle of expansion of the generated gas droplet flow at the two ends of a nozzle. . : The attachment of an attached atomizer (spray ejector) to a gas powered nozzle will allow the cone angle of the generated gas droplet flow spray to be increased to 12 degrees, 'which will significantly reduce the gas droplet flow Shooting distance. A few 廿 < inconsistency makes the known fire extinguishing device of the prior art unable to be applied to the extinguishing - wider range 100274.doc 1287463, fire ^. For example, a long-range gas granule flow guided by a narrow spoke can reduce the flammable liquid and will not provide effective fire extinguishing and safe operation by firefighters due to splashing of liquid. The use of additional spray spray benefits in prior art known devices will allow the resulting atomized gas droplet flow to have a large spray split y angle, but in this case the fire extinguishing agent exit distance is substantially reduced J, thus making it unsuitable for extinguishing high-intensity flames caused by flammable liquid materials. A variety of devices are currently used to adjust the parameters of a gas droplet flow. In particular, the U.S. Published Patent Application No. 2003/0047327 A1 (IPC_7, A62C 2/〇〇, issued March 13, 2003) discloses a type including a sorrow/;, L into air and liquid Portable fire extinguishing device for a liquid atomizer of a hybrid regulator. The above regulators only affect the turbulence of a liquid flow field and therefore only act on the foam generated in the flow of the fire extinguishing agent. The effect of the turbulent flow of a first-class field on the expansion angle of a fire-fighting agent flow can be manifested under a predetermined condition; however, this effect is not revealed in known sources of information. One of the portable fire extinguishing devices of the present invention is disclosed in U.S. Patent No. 5,623,995 (IPC-6 A 62C 25/00, issued Apr. 29, 1997). The prior art portable fire extinguishing device includes a storage tank for containing fire extinguishing liquid, a system for supplying liquid under pressure, a liquid flow cyclone (turbulence enhancer), and a foam flow Nebulizer. The liquid supply system of the device is constructed as the same diaphragm. The liquid flow cyclone is disposed in a cylindrical mixing chamber, a liquid containing a foam generating aid is supplied into the mixing chamber in an axial direction, and - under a dust of 100274.doc 1287463 All line directions are supplied. The intensive mixing of the liquid and gas in the channels of the mixing chamber between the guiding elements will result in the creation of a strong foam. The resulting foam is further delivered through a flexible hose to a nozzle that is configured to form a forming channel. A pressurized gas is used in the apparatus as a working medium for driving the diaphragm pump and supporting one of the most efficient turbulence of the liquid stream. The apparatus considered, and the other embodiments of the prior art, do not provide an adjustment to the angle of expansion of the resulting fire suppressing agent flow field over a predetermined droplet atomization range and the exit distance of the gas droplet flow. Various different types of liquid atomizers are currently known which can be utilized to generate a gas droplet flow in a fire suppression system. U.S. Patent Application Serial No. US 2003/0047327 (IPC-7 A62c 2/00, issued on Mar. 3, 2003), which is incorporated herein by reference, discloses a liquid atomizer which is configured as a nozzle equipped with a forming channel. The nozzle inlet end is in fluid communication with a supply line via a cylindrical chamber and a cylindrical groove having a minimum passage section, and the cylindrical chamber and the cylindrical channel are successively disposed. The nozzle is sleeved with an axial cylindrical insert that is adjustable in length and configuration. The displacement of the adjustable insert relative to the outer portion of the nozzle causes a change in liquid hazard and, therefore, a degree of turbulence in the flow field and/or a change in efficiency. Flow field fluidization in known embodiments of the prior art can also be adjusted by an adjustment nut assisting the advancement of its tip into the liquid flow field. It should be noted that the foregoing embodiment owes a device that modifies the taper angle of the generated gas droplet flow spray by the lack of 100274.doc 1287463. The closest approximation of the liquid atomizer of the present invention is the atomizer disclosed in the inventor's USSR Patent No. 292,678 (IPC AOlm 7/22, issued Apr. 22, 1971). The atomizer includes a nozzle equipped with a molding channel, a cylindrical chamber connected to the nozzle injection port at one end thereof, and a liquid flow cyclone. The forming channel of the atomizer is composed of two elements, a tapered tube and a diffuser. A liquid flow cyclone is enclosed within the nozzle diffuser pocket and is configured as a sloping plate having two acute angled edges disposed at an angle of 30 degrees to each other. The liquid is supplied to the atomizer under pressure, and the liquid flows in the tapered tube member. It is accelerated to abut the sharp corner of the cyclone, which causes the liquid flow to split into smaller droplets and to the nozzle diffuser. The resulting gas droplet flow is accelerated. The flow of gas droplets produced by discharge from the outlet end of the nozzle is configured as a conical spray. However, because the swash plate encased in the recess of the tapered tube creates additional resistance to liquid flow, the prior art known device does not provide a high velocity gas granule flow having a uniform droplet size. Therefore, although the uniformity of the gas droplet flow in the spray is improved, the liquid flow velocity is substantially lowered. It should also be noted that the sharp-edged edges of the parallel guides of the swirler deflect the generated flow field in only one direction, i.e. perpendicular to the edge surface of the swirler. As a result of this, the gas droplet flow spray is expanded in one direction at the outlet end of the nozzle. The resulting flow field spray thus has an elliptical cross section. The atomizer of the prior art 100274.doc 1287463 limits its practical application due to the non-uniform expansion of the gas droplet flow. Furthermore, the atomizer of the prior art does not provide an adjustment of the taper angle of the gas droplet flow spray and at the same time maintains the velocity of the liquid particles directed to the flame. SUMMARY OF THE INVENTION It is an object of the present invention to provide an adjustment of a taper angle of a generated gas droplet flow spray at a predetermined distance from which a fire extinguishing agent is ejected. The object of the present invention is to facilitate the adjustment of the taper angle of a generated gas droplet flow spray under the following conditions: - the axial velocity of the liquid droplets when changing the taper angle of a gas droplet flow spray Will not be significantly reduced (thus, the distance between the injection of a fire extinguishing agent or any other agent will not be significantly reduced); - When changing the taper angle of one of the top field sprays, it is related to the size of the drop The uniformity of the gas droplet flow should be maintained; - when changing the cone angle of one of the gas droplet streams, the liquid flow rate through the nozzle must be maintained. The technical result obtained through the working solution set for the portable fire extinguishing device is a good attack efficiency in extinguishing different types of flames, including those caused by combustible liquids. The claimed technical results are achieved by the use of a portable fire extinguishing device and a liquid atomizer designed in accordance with the present invention. The portable fire extinguishing device comprises a storage tank for containing fire extinguishing liquid, a system for supplying pressurized liquid, and a liquid flow equipped with a guiding element 100274.doc -10- 1287463 liquid atomizing end It is connected to the L device and connected to the storage tank via the supply line. The liquid atomizer includes a nozzle having a molding channel and a cylindrical chamber connected to the nozzle inlet. One

The guiding elements 18 of the swirler 17 are evenly distributed over the sleeve. In one orientation of the cross section of the cylindrical chamber (as shown in Figure 4). The % of the slit of the swirler 17 defined by the edge of the adjoining guiding element 18 is rectangular in shape and causes the slit 26 to be in one of the projections of the cylindrical chamber of the sleeve 13 Through-type (as shown in Figure 4). The surface of the guiding element 18 in the swirler 17 may be flat as shown in Figure 5 or concave as shown in Figure 6. When a guiding member 18 having a flat surface is used, the optimum bevel angle with respect to the guiding surface of the cyclone 17 and the longitudinal axis of symmetry of the sleeve 13 is 45 degrees (as shown in Fig. 5). A preferred embodiment is a swirler 17 having a guide member with a concave operating surface (as shown in Figure 6). In this case, it can reduce the hydraulic loss of the liquid flow in the round to the middle. In an embodiment of the cyclone 17 shown in Figure 6, a flat edge 31 having a 45 degree angle with respect to the axis of symmetry of the swirler is disposed on the opposite side of the guiding element 18 100274.doc 1287463 in the cavity With the inlet end in the supply line 8 and reaching a controllable normally closed valve (not shown). The valve is mounted in the body of the grip 6. The valve is controlled via a trigger type mechanism 7. The pressure intensity of the liquid supply system for supplying the liquid to the atomizer is pre-regulated by the desired flow velocity of 0.2 to 0.4 Ι/s of the generated gas droplet flow. The selection of the pressure strength in the storage tank will take into account the hydraulic losses in the supply line 8 and in the liquid atomizer 5. In an example of an embodiment of the invention now under test, the gas droplet flow velocity through the atomizer 5 is associated with the desired fire extinguishing capability, which is used when using an atomizer Part of a portable fire extinguishing device is quite important. A storage box 气球 and a balloon-shaped container 2 equipped with a pressurized gas line and fittings are installed in a firefighter backpack or in a portable container. The generation of the gas granule flow is provided by the firefighter using the liquid atomizer 5 affixed to the grip 6 and actuated by the trigger type mechanism 7. When the firefighter presses on the button type mechanism 7, the controllable valve on the grip 6 is opened and the liquid is delivered to the inlet of the connecting tube 14 of the atomizer 5 under pressure (8 + 10) 105 Torr. . The liquid stream is fully swirled as it passes through the channel defined by the slit 16 of the diaphragm 15 and the guiding element 18 of the cyclone 17. The orientation of the guiding elements 18 of the swirler 17 on the section of the cylindrical chamber of the casing 13 enhances the increase in the luxury flow of most of the peripheral portion of the liquid stream. Turbulence of the liquid stream can be achieved by using a cyclone equipped with guiding elements having differently shaped surfaces. For example, a cyclone 17 having a flat guiding element 18 can be utilized for this purpose (as shown in Figure 5). This implementation of the cyclone 17 is 100274.doc -18- 1287463 at the inlet end where the cavitation bubbles grow densely and rupture. In the passage through the portion 24, the liquid flow is separated from the nozzle wall surface, the cavitation bubbles are densely broken, and the finally turbulent liquid droplets generated in the tangential direction are split. Upon flowing through the portion 24 of the nozzle 12, a vaporous gas phase is subsequently produced in the liquid stream. This causes a decrease in the flow density and the acceleration of the two-phase flow in the outer portion of the channel of the nozzle 12. The static pressure in the cavities of the outer conical portion 24 of the nozzle 12 is low and can be commensurate with a cavitation pressure value. This causes the ambient air to flow directly into the cavity bounded between the gas liquid flow field and the nozzle wall. The reverse air flow along the outer portion 24 of the nozzle 12 enhances the vortex procedure. This condition causes the holes to collide densely in the liquid stream and the liquid stream to split. As a result, a finely dispersed gas droplet flow is formed, and the liquid droplets have all the line flow velocity components. One of the generated flows, defined as the ratio of the total volume to the surface of a drop of particles, has an average droplet size of from 2 to 400 microns and allows individual droplet sizes in the flow to range from 4 to 400. Changes in the micron range. It should be noted that 'the range of droplet sizes indicated in the generated flow is consistent with an optimum range of droplet sizes from 200 to 300 microns, which is most effective for extinguishing the solid combustibles. Flames. It has been established during the experimental test that the generated flow has a different spray cone angle with all line down speed values. The shape of the liquid stream spray can thus be varied via adjustment of the tangential flow velocity at the inlet of the nozzle. The tangential liquid flow velocity in accordance with the present invention is adjusted by varying the azimuthal position of the slit 16 of the diaphragm 15 relative to the slit 26 of the cyclone 17.

The limitation of the angular movement is limited by the projection 29 formed on the sleeve 13 and is fixed by the projection during the advancement of the sleeve along the wall of the slot 30. In its extreme position, the slot 30 is formed in the end portion of the connecting tubular member 14 (shown in Figure 3). In the initial position of the sleeve 13, the slit 16 is opposed to the slit of the swirling flow. In this case, the liquid stream is split into individual gas streams generated in the slit 16 of the diaphragm crucible 5. After passing through the membrane, a portion of the gas stream immediately abuts the surface of the guide member 18 of the cyclone crucible 7, while a major portion of the gas stream flows through the slit 26 without being forced to fluidize. A portion of the turbulent fluid stream is further directed into the cylindrical chamber of the casing bore 3, wherein a single flow is produced by the individual gas streams. The liquid pressure at the input section of the nozzle is approximately 8 105 Pa. After the liquid stream is accelerated and atomized, a stream of atomized liquid having a spray cone angle of about 20 degrees is created in the forming channel of the nozzle 12. The spray distance of the atomized gas droplet flow is greater than 1 〇 m, and the liquid flow velocity is from 0.2 to 0.4 Ι/s. A narrow radiant channel 100274.doc -21 - 1287463 produced by a liquid atomizer can be used to extinguish a fire field caused by a solid combustible flame. In order to extinguish the fire field generated by liquid flammable and highly flammable liquids, the cone angle of the gas droplet flow spray must be increased. To achieve this function, the firefighter actuates the sleeve 13 to move relative to the angle of the connecting tube 14 until the projection 29 of the sleeve 13 extends into the slot 30 to a fixed extreme position. In the illustrated position of the sleeve 13, the slit 6 of the diaphragm 15 is disposed on the opposite surface of the guide member 18 of the swirler 丨7. Some of the liquid gas flowing through the slit 16 of the diaphragm 15 is deflected by the surface of the guiding member 丨8. In this case, the turbulent fluid flow is generated in the cylindrical chamber of the sleeve 13 so as to flow along the wall surface of the chamber. The resulting liquid stream having a turbulent peripheral portion is discharged into the forming channel of the nozzle 12 where it is accelerated and atomized. An atomizing gas droplet flow is produced at the outlet of the nozzle 12 and having a spray cone angle of about 3 degrees. Studies have been conducted to show that, regardless of the taper angle of the spray, the size of the droplets, the flow field velocity, and the exit distance from the gas droplet flow are not substantially changed in relation to the uniformity of the gas droplet flow. The use of a liquid atomizer as part of the fire extinguishing device of the present invention will cause the spray cone angle of the atomized liquid stream to be varied within a range of 20 to 3 degrees, which can be atomized by a firefighter rotating liquid The casing 13 is completed. Changing the cone angle of the gas droplet flow within the indicated range does not affect the basic parameters of the flow'. This proof can be consistent with the predetermined requirements, and thus the technical result can be determined. Industrial Applicability of the Invention 100274.doc -22- 1287463 The present invention can be used in fire suppression systems and as part of processing equipment for use in different functions. In addition to the use of liquid atomizers in fire suppression systems, they can be used for combustion of fuels for thermal engineering and transportation, as well as for environmental wetting and disinfection and insecticidal spraying. As a fire extinguishing device, the present invention can be used in both fixed and mobile fire extinguishing facilities for fire extinguishing for a variety of purposes, such as hospitals, library and museum rooms, on board, on airplanes, and for slowing down in open spaces. The fire field, etc. The application examples of the embodiments of the present invention are described as preferred, although their claims based on the present invention do limit any other possible embodiment patterns that may be well known to those skilled in the art.
