Definitions
- the invention relates to a Feuerloschnebelduse of the ax mentioned in the preamble of claim 1.
- Mist-generating extinguishing nozzles are becoming increasingly important in fire fighting.
- a mist with droplets as fine as possible there is water with a very high surface volume ratio. This leads to strong cooling of the flames and therefore a very good extinguishing effect.
- a fine mist also has a strong smoke-washing effect and thus combats the annoying smoke formation.
- Fire-extinguishing mist nozzles are known which can generate short-term fog impulses with high-pressure gas in an extremely complex construction.
- Atomizing ejectors are available for generating mist with an ejector that is fed with water under high pressure.
- Such mist nozzles have the advantage of continuous operation and simple construction, but the disadvantage of extremely short range, so that they can only be used for fire fighting to a very limited extent.
- a generic fire extinguishing nozzle is known from US 5,284,298.
- an ejector rotating around an axis generates a helical water jet with a forward-directed pulse. This results in air entrainment, which leads to nebulization of the water jet.
- Suitable ejectors are commercially available, for example in the form of ejectors of high-pressure cleaning devices operated at approximately 100 bar.
- a disadvantage of the known construction is the short range of the fog beam.
- No. 4,715,539 shows a nozzle for high-pressure cleaning devices which is arranged stationary on the device and is surrounded by a tube which is closed at the rear and which serves as a handle.
- the object of the present invention is to design a generic fire-fighting nozzle with a longer range.
- a concentric jacket tube which is open at the end, is provided, which increases the air entrainment effect of the jet and thus results in an enormous increase in the range of the fog jet.
- the range of the pure water jet is far exceeded.
- An air blower is not required.
- the construction according to the invention can produce fog jets of very high range up to over 10 m, which consist of the finest water droplets and which provide the desired extinguishing effect and smoke washing effect to an outstanding extent.
- the ejector can be driven all round, for example with a motor. However, the features of claim 2 are preferably provided. If the ejector is tilted slightly backwards in the direction of the jet, it acts as a lawn sprinkler itself, so that an additional rotary motor is not required.
- claims 3 to 5 are advantageously provided. According to claim 4, there is an optimal fog effect and a large range of the fog beam with a small size. According to claim 5, e.g. two ejectors arranged opposite each other, the fog power and the fog effect.
- a fire-fighting nozzle according to the invention is shown schematically in one embodiment. Show it:
- Fig. 1 shows a section along line 1-1 in Figure 2 and
- FIG. 2 shows a section along line 2 - 2 in FIG. 1.
- Figures 1 and 2 show in different sectional views a fire valve nozzle 1 with an inlet pipe 2 (Fig. 1) through which water under high pressure of 100 bar, for example, the fixed part 3 of a rotary tube bearing 3, 4 is supplied, the freely rotatable part 4 via a in the axis of the pivot bearing tube 5 supplies a cross tube 6.
- a cross tube 6 At the ends of the cross tube 6, two ejectors 8 are arranged at the same distance from the axis of rotation 7, which, with their jet openings 9 (FIG. 2), generate water jets 10 parallel to the axis of rotation 7.
- the rotatable part 4, 5, 6, 8 of the arrangement shown is driven in the direction of rotation shown by arrow F in FIG. 2.
- a separate motor for example a water motor or an electric motor, could be provided.
- the rotation is generated in a very simple manner in the manner of a lawn sprinkler by slightly tilting the direction of the jet openings 9 counter to the direction of rotation F, as can be seen from FIG. 2.
- the angle by which the water jets 10 are tilted relative to the vertical to the plane of the drawing in FIG. 2 can be, for example, 5 °.
- a casing tube 11 Arranged around the nozzle arrangement shown is a casing tube 11 which has a larger diameter than the circulating circuit of the ejectors 8 and which corresponds in its length to approximately twice the diameter. It begins with its rear end at least at the ejectors 8 and has a length that preferably corresponds to twice the diameter. In one embodiment, the diameter is approximately 15 cm and the length is approximately 30 cm.
- the casing tube 11 is fastened with 4 struts 12 to the fixed part 3 of the tube pivot bearing 3, 4.
- the illustrated fire nozzle 1 can e.g. be mobile to be held in the hand. It is then to be connected to the inlet pipe 2 via a hose (not shown).
- the fire-extinguishing nozzle 1 shown is connected in a stationary manner to a supply pipe 13 which, for example, is permanently installed in a building and is connected to a suitable high-pressure water pump. Further fire extinguishing mist nozzles according to the invention can be provided spaced apart on the tube 13. A traffic tunnel can be supplied with such an arrangement, for example.
- the illustrated fire valve 1 is supplied with water under high pressure of, for example, 100 bar via the inlet pipe 2, with which the Rotary bearings 3, 4, the ejectors 8 are acted upon. With their jet openings 9 in the direction of the axis 7, these generate two water jets 10 which, in the case of the aforementioned slight tilting, cause the ejectors to be driven in the direction of the arrow F.
- the massive water jets 10 which have not yet been atomized when exiting the ejectors 8 and which e.g. have a diameter of a few tenths of a millimeter, consequently run on screw tracks in the direction of the axis of rotation 7 and, supported by the casing tube 11, tear an air stream with high speed.
- a fine mist jet results at the end of the casing tube 11 in the beam direction, which has a range of more than 10 meters in the dimensions of the fire-fighting nozzle 1 and has a diameter of a few meters there.
- the generated mist has extremely small droplets, so that it does not sink to the ground, but is taken along as a cloud by air currents.
- the fire-fighting nozzle 1 is equipped with two ejectors 8. It is also possible to provide only one ejector or, for example, 3 or more ejectors.
- the suction side of the casing tube 11 e.g. be arranged with a separate motor driven air blower to advantageously increase the air flow.
- the rotational speed of the ejectors 8 can advantageously be regulated or braked in order to somewhat reduce the nebulizing effect. Thereby the droplet large increases and increases the range and punch impulse of the fog beam.
