Definitions
- the invention relates to a method for fighting fires, in which a directed jet of foam is applied in order to cover the source of the fire. Furthermore, the invention relates to a device which is suitable for carrying out the method. Devices of this type are used in stationary or mobile fire extinguishing devices in order to suffocate a fire through a foam, for example if the use of water as a liquid is not possible.
- a device suitable for extinguishing fires with foam is known from British Patent 1,018,431.
- the device described in this document has a foam tube which surrounds a nozzle body with a cylindrical section.
- the nozzle body has a nozzle from which liquid is discharged.
- the known device has an inlet opening on its rear face.
- several inlet openings are distributed over the cylindrical circumference of the foam tube.
- the erasing foam produced by means of such a device can be discharged in a directed jet. This has the advantage that the foam is released with relatively high kinetic energy, so that it
- CONFIRMATION COPY can cover large throwing distances and the fire can first be put down from a great distance and then extinguished from a short distance. At the same time, the concentrated application of the extinguishing foam jet causes the foam to hit the fire site in a compact form and, after impact, forms a tight cover through which the fire is suffocated.
- Extinguishing foam jet wagging movements are carried out. Through these movements, the jet sweeps over the fire area, so that after some time it is covered with extinguishing foam. In practice, however, it turns out that because of the incomplete partitioning of the fire and the high ambient temperature, an expansion of the fire to neighboring areas and objects cannot always be prevented.
- the object of the invention is to provide a method of the type mentioned at the outset and a device which is suitable for carrying out the method and which allow the extinguishing of spreading fires with a reduced risk of fire spreading.
- this object is achieved in that, in addition to the extinguishing foam jet, an extinguishing mist is applied, which cools the volume of space surrounding the source of the fire.
- the method according to the invention combines the extinguishing method known per se, for example from German utility model 295 18 911.8, using extinguishing mist with the method for extinguishing by means of an extinguishing foam. It has been shown that the extinguishing mist and the extinguishing foam jet complement each other in an optimal manner, particularly when fighting large-scale or large-volume sources of fire. This happens because, on the one hand, the fire is fought directly by using the directed extinguishing jet and the surface of the fire is successively covered with foam. On the other hand, the gas space that surrounds the fire is cooled by the loosening mist.
- the introduction of the extinguishing mist ensures that the ambient temperature of the fire is reduced even in such areas if the fire has not yet been directly covered by the extinguishing foam, if that Fire in the relevant areas is still burning. This prevents the fire from spreading, for example due to self-ignition of objects adjacent to the source of the fire, as a result of the high temperatures in the vicinity of the fire.
- the loosening mist is deployed optionally depending on the position of a control device. This enables the extinguishing agents introduced into the area of the fire (Extinguishing foam / extinguishing liquid mist) depending on the respective fire situation.
- the foam pipe according to the invention can be used particularly advantageously in connection with quenching devices in which the quenching liquid is under high pressure, i.e. at pressures above 40 bar.
- a further advantageous embodiment of the method according to the invention is characterized in that mist liquid is applied in the form of several individual jets, the respective origin of which is arranged in the immediate vicinity of the origin of the mousse foam. So it can be easily ensured that the
- This embodiment is therefore particularly advantageous when the method according to the invention is carried out with a mobile fire extinguishing device in which the fireman holds a mobile fire extinguishing gun in his hand.
- at least one single jet is directed in a direction away from the source of the fire, so that the rear area of the extinguishing device is also reliably seized by the release mist.
- a device which is particularly suitable for carrying out the method according to the invention and which is equipped with an eraser nozzle head which comprises an eraser foam generating device for producing a directed eraser foam jet is characterized in accordance with the invention in that the eraser nozzle head comprises additional eraser nozzles for generating erasing liquid mist jets.
- At least one of the quenching nozzles can preferably be oriented such that the quenching liquid spray emerging from it is directed in the direction of the source of the fire, while at least one further quenching nozzle is oriented such that the quenching liquid spray emerging from it exits in a direction normal to the exit direction of the clearing foam jet.
- the Loschdusenkopf 1 of the portable fire gun L is rotationally symmetrical and points to it End face an end face 2.
- a central nozzle 3 is arranged in the center of the end face 2.
- the central nozzle 3 is connected to a first supply line 4 of the nozzle L, which runs in the housing tube R of the nozzle L.
- a circumferential inclined surface 5 is formed on the end face 2 of the Loschdusenkopf 1, which backs away from the front end face 2 at an angle ⁇ of approximately 45 °.
- Loose nozzles 6 are arranged on the inclined surface 4 and are connected to a second supply line 7 of the lance gun L, which also runs in the housing tube R.
- the loosening nozzles 6 are arranged at regular angular intervals from one another on a circle which is aligned concentrically with the opening of the central loosening nozzle 3.
- the outlet of the fog jet emerging from them when pressurized with loosening liquid is directed essentially at right angles to the inclined surface 5, so that the fog jets of the nozzle nozzles 5 are directed essentially in the same direction as the axis emerging parallel to the longitudinal axis X of the nozzle nozzle 1, which passes through the central one Loschduse 3 is generated.
- the supply lines 4, 7 can be supplied with extinguishing fluid simultaneously or individually via a manually adjustable valve V.
- the inclined surface 5 is adjoined by a radially circumferential jacket surface 8, which extends axially parallel to the longitudinal axis X of the squeegee head 1 and on which further sockets 9 connected to the supply line 7 are arranged.
- the quenching nozzles 9 also give one when the quenching fluid is applied Quenching jet. However, this has a component directed radially to the longitudinal axis X of the nozzle nozzle 1 and a component directed in the direction of the valve V, so that the nozzle mist jets emerging from the nozzle nozzles 9 fill the space surrounding the nozzle L from the rear and to the side.
- a foam tube 11 is attached to the central nozzle 3 via a sleeve 10.
- the foam tube 11 has a nozzle body 12 on which an injector nozzle 13 projecting into the foam tube 11 is formed.
- the bore 14 of the injector nozzle 13 is connected to the central valve nozzle 3 via a chamber of the nozzle body 11 and the sleeve 10. Between the wall of the foam tube 11 and the nozzle body 12, exit openings (not shown here) are formed, through which ambient air is drawn into the foam tube.
- the supply lines 4 or 7 are simultaneously or individually supplied with extinguishing fluid, preferably water.
- the extinguishing fluid has a high pressure of more than 40 bar in both supply lines.
- the loosening nozzles 6 and 9 When the supply line 4 is pressurized, the loosening nozzles 6 and 9 generate a loosening mist in which the individual liquid droplets have a small volume and emerge into the environment in finely divided form with high kinetic energy from the nozzle openings of the loosening nozzles 6,9.
- the mist jets emerging from the obliquely forwardly pointing nozzles 6 reach the surroundings of the source of the fire and cool the gases present there with evaporation and the associated displacement of the oxygen.
- the central outlet nozzle 4 becomes a directional one which is mixed with a foam-forming additive
- Loosening liquid jet discharged from the central loosening nozzle 3 under high pressure.
- This jet enters the chamber of the nozzle body 12 of the jet pipe 11 and is additionally swirled there.
- the swirled extinguishing fluid jet passes through the nozzle bore 13 m into the foam tube 11, into which it draws air in via the inlet openings of the foam tube in the manner of the Venturi effect.
- This air mixes with the finely atomized quenching fluid to form a fine-pored foam.
- This foam emerges from the foam tube 11 with high kinetic energy and reaches the source of the fire as a directed, compact foam foam jet.
- Radiation heat protection for the operating personnel increases the effectiveness and usability of the foam generated by the high-pressure foam generator placed on the central nozzle.
- the foam tube 12 also leads to a considerable improvement in the throwing distance of the extinguishing agent jet emerging from it when no foam-generating additive is added to the extinguishing agent, but only the extinguishing liquid itself emerges from the foam tube 12 as a jet of high kinetic energy.
- the use of the foam tube 12 for pure liquid extinguishing is advantageous if, for example, a directed jet of liquid is required to reach the source of the fire from a greater distance.
- the clearing liquid jet concentrated through the foam tube can be used to achieve a wetting of embers nests hidden deep inside the fire source by means of a targeted jet.
