Description

Die Erfindung betrifft einen mobilen Feinsprühfeuerlöscher entsprechend dem Oberbegriff des ersten Anspruches.The invention relates to a mobile fine spray fire extinguisher according to the preamble of the first claim.

Die Erfindung ist zum Löschen glutbildender und flüssiger Stoffe einsetzbar. Sie ist besonders geeignet für den Einsatz an Orten, an denen ein flüssiges Löschmittel größere Schäden anrichten kann. In der Feuerlöschtechnik wird im Hinblick auf die Mobilität der Löschanlage zwischen mobilen und stationären Feuerlöschanlagen unterschieden. Stationäre Feuerlöschanlagen sind Löschanlagen, die in Gebäuden fest installiert sind. Sie weisen einen Löschmittelbehälter und Leitungen zu den Löschaggregaten auf. Dabei handelt es sich in der Regel um Löschdüsen, wobei Sprühdüsen mit einem Sprühwinkel bis 60 ° bekannt sind. Dieser Sprühwinkel wird so weit eingestellt, daß möglichst eine große Fläche der unter der Sprühdüse befindlichen Fläche übersprüht wird, um die Anzahl der Löschdüsen im Raum gering zu halten und nur die notwendigste Menge an Löschmittel zu versprühen. Um möglichst wenig Löschmittel zu versprühen sind Feinsprühdüsen nicht unüblich.The invention can be used for extinguishing glowing and liquid substances. It is particularly suitable for use in places where a liquid extinguishing agent can cause major damage. With regard to the mobility of the extinguishing system, a differentiation is made between mobile and stationary fire-extinguishing systems in fire-fighting equipment. Stationary fire extinguishing systems are extinguishing systems that are permanently installed in buildings. They have an extinguishing agent tank and lines to the extinguishing units. These are usually extinguishing nozzles, with spray nozzles are known with a spray angle up to 60 °. This spray angle is adjusted so that as far as possible a large area of the area located below the spray nozzle is oversprayed to keep the number of extinguishing nozzles in the room low and to spray only the most necessary amount of extinguishing agent. To spray as little extinguishing agent are fine spray nozzles not uncommon.

Mobile Anlagen bestehen in der Regel aus einem tragbaren oder fahrbaren Löschmittelbehälter, an dem eine Leitung in Form eines flexiblen Schlauches angeordnet ist und eine Löschdüse. Mobile Anlagen sind darauf gerichtet, Brände möglichst schnell zu löschen, wobei mittels Druckgases eine große Menge flüssigen Löschmittels innerhalb kürzester Zeit über den Brandherd verteilt wird. Der Vorteil mobiler Löscher besteht darin, daß eine Person das Löschmittel zielgenau auf den Brandherd steuert. Das Löschmittelvolumen beträgt bei fahrbaren mobilen Feuerlöschanlagen bis 50 Liter.Mobile systems usually consist of a portable or mobile extinguishing agent container, on which a line is arranged in the form of a flexible hose and an extinguishing nozzle. Mobile systems are aimed at extinguishing fires as quickly as possible, with the aid of compressed gas, a large amount of liquid extinguishing agent is distributed over the fire within a very short time. The advantage of mobile extinguishers is that a person controls the extinguishing agent accurately to the source of fire. The volume of extinguishing agent in mobile mobile fire extinguishing systems is up to 50 liters.

Durch die Tatsache, daß innerhalb kürzester Zeit viel Löschmittel mit großem Tropfendurchmesser auf dem Brandherd verteilt wird, kann es zu größeren Löschmittelschäden kommen. Seit mit mobilen Feuerlöschanlagen gelöscht wird, besteht dieses Problem, daß erheblicher Schaden sowohl bei Verbrauchern als auch bei Versicherungen entsteht und seit geraumer Zeit der Bedarf besteht, auch mobile Feuerlöschanlagen so zu gestalten, daß möglichst geringe Wasserschäden entstehen. Mit den derzeit bestehenden mobilen Anlagen konnte dieses Problem bisher nicht gelöst werden.Due to the fact that within a very short time much extinguishing agent with large drop diameter is distributed on the fire, it can lead to larger extinguishing agent damage. Since extinguished with mobile fire extinguishing systems, there is this problem that considerable damage both consumers and insurance and arises for some time, the need to design mobile fire extinguishing systems so that the least possible water damage. With the currently existing mobile systems this problem could not be solved so far.

Aus DD 299 098 ist ein Verfahren und eine Vorrichtung zum Löschen von Bränden mittels automatischer, mobiler und stationärer Feuerlöschanlage auf der Basis von Wasser und Treibgas bekannt, wobei das Wasser in einem Wasserbehälter und das Treibgas getrennt davon in einem Druckbehälter gespeichert werden und beide Fluide nach dem Öffnen des Schnellöffnungsventils in eine nach dem Vergaserprinzip funktionierende Zerstäuberkammer gelangt, dort zu einem Aerosol zerstäubt werden und nach dem Verlassen der Zerstäuberdüse den Brand durch Wärmeentzug löscht. Treibgas und Wasserbehälter sind in verschiedenen Räumen angeordnet, wobei die Zerstäuberkammer mit einem fest installierten Rohrleitungssystem verbunden ist. Bei der vorliegenden Vorrichtung handelt es sich nicht um einen Feuerlöscher, sondern eine Feuerlöschanlage, die nach dem Vergaserprinzip arbeitet. Eine direkt auf den Brandherd gerichtete Angriffseinrichtung ist bei dieser Anlage nicht vorhanden.Out DD 299,098 a method and an apparatus for extinguishing fires by means of automatic, mobile and stationary fire extinguishing system on the basis of water and propellant gas is known, wherein the water in a water tank and the propellant separated be stored in a pressure vessel and both fluids passes after opening the quick opening valve in a functioning according to the carburetor atomizer, where they are atomized to form an aerosol and extinguished after leaving the atomizer the fire by heat removal. Propellant and water tanks are arranged in different rooms, wherein the atomizer chamber is connected to a fixed piping system. In the present device is not a fire extinguisher, but a fire extinguishing system that operates on the carburetor principle. An attacking device aimed directly at the source of the fire does not exist in this system.

In GB 2 320 189 A ist ein transportabler Feuerlöscher beschrieben, der eine Sprühpistole mit einer Sprühdüse aufweist, mit der ein Sprühnebel erzeugbar ist, wobei die Sprühdüsentröpfchen in einem Winkel von 130 Grad versprüht werden. Derartige Sprühnebel sind für das gezielte Besprühen eines Brandherdes wenig geeignet.In GB 2 320 189 A a portable fire extinguisher is described, which has a spray gun with a spray nozzle, with which a spray is generated, wherein the Sprühdüsentröpfchen are sprayed at an angle of 130 degrees. Such sprays are not very suitable for the targeted spraying of a fire.

Aus WO 2004/10 59 57 A1 ist zwar eine Düsenanordnung zur Erzeugung ebener Sprühfelder bekannt, mit der gezielt ein Sprühnebel auf einen Brandherd gerichtet wird, allerdings handelt es sich dabei um eine fest installierte Feuerlöschanlage mit Rohren.Out WO 2004/105957 A1 Although a nozzle assembly for generating planar spray fields is known, with the targeted a spray is directed to a fire, but this is a fixed fire extinguishing system with pipes.

Aus GB-A-2 320 189 ist ein mobiler tragbarer Feuerlöscher zum Löschen glutbildender und flüssiger Stoffe, vorzugsweise mit einem Löschmittelbehälter, bestehend aus dem Löschmittelbehälter, dem wäßrigen Lösungsmittel, dem Ventil, der Löschmittelleitung und der Löschdüse mit einer Feinlöschdüse als Löschdüse und einem Speicher für Druckgas am oder im Löschmittelbehälter bekannt.Out GB-A-2 320 189 is a portable portable fire extinguisher for extinguishing glowing and liquid substances, preferably with an extinguishing agent container consisting of the extinguishing agent container, the aqueous solvent, the valve, the extinguishing agent line and the extinguishing nozzle with a fine extinguishing nozzle as extinguishing nozzle and a memory for compressed gas on or in the extinguishing agent container known.

Dem Dokument sind keine Angaben darüber zu entnehmen, wie die Sprühdüse gestaltet sein muß, damit ein geringer Löschmittelverbrauch vorhanden ist.The document gives no information about how the spray nozzle must be designed so that a low extinguishing agent consumption is present.

AU 49 161 90 A offenbart ein Sieb im Löschmittelbehälter. Allerdings sind diesem Dokument keine Feinsprühdüsen mit einem bestimmten Sprühwinkel zu entnehmen. AU 49 161 90 A discloses a sieve in the extinguishing agent container. However, this document does not disclose fine spray nozzles with a particular spray angle.

DD 209 098 A7 beschreibt einen Feuerlöscher, bei dem als Treibgas CO2, N2, AR oder Druckluft eingesetzt werden. Auch dieser Feuerlöscher weist keine Feinsprühdüsen mit einem bestimmten Sprühwinkel von maximal 30° auf. DD 209 098 A7 describes a fire extinguisher, are used in the propellant CO 2, N 2, AR or compressed air. Also, this fire extinguisher has no fine spray nozzles with a certain spray angle of 30 ° maximum.

Mobile Feuerlöscheinrichtungen, deren Angriffsmittel bei geringem Wasserverbrauch und hoher Löschwirkung zielgenau am Brandherd einsetzbar sind, sind nicht bekannt.Mobile fire extinguishing equipment, the means of attack with low water consumption and high extinguishing effect are accurately used at the source of fire, are not known.

Es ist daher Aufgabe der Erfindung, einen mobilen Feinsprühfeuerlöscher zu entwickeln, mit dem Brände möglichst rasch und bei geringstem Schaden durch die Löschflüssigkeit gelöscht werden können.It is therefore an object of the invention to develop a mobile fine spray fire extinguisher, with the fires can be extinguished as quickly as possible and the slightest damage by the extinguishing liquid.

Diese Aufgabe wird durch einen mobilen Feinsprühfeuerlöscher nach den Merkmalen des ersten Patentanspruches gelöst.This object is achieved by a mobile fine spray fire extinguisher according to the features of the first claim.

Unteransprüche geben vorteilhafte Ausgestaltungen der Erfindung wieder.Subclaims give advantageous embodiments of the invention again.

Die Erfindung sieht einen mobilen, vorzugsweise einen tragbaren Feinsprühfeuerlöscher vor, welcher aus dem Löschmittelbehälter mit dem wäßrigen Löschmittel, dem Ventil, der Löschmittelleitung und der Löschmitteldüse besteht, wobei die Löschmitteldüse eine Feinsprühdüse darstellt und ein Speicher für Druckgas am oder im Löschmittelbehälter angeordnet ist.The invention provides a mobile, preferably a portable fine spray fire extinguisher, which consists of the extinguishing agent container with the aqueous extinguishing agent, the valve, the extinguishing agent line and the Löschmitteldüse, wherein the extinguishing agent nozzle is a Feinsprühdüse and a memory for compressed gas is arranged on or in the extinguishing agent container.

Vorteilhafterweise weist die Feinsprühdüse einen Sprühwinkel von maximal 30 Grad auf. Damit ist gewährleistet, daß der entstehende Feinsprühnebel in einem engen Winkel auf dem Brandherd befördert wird. Die Anwendung der Feinsprühtechnik bietet sich in besonderer Weise für den mobilen Bereich an. Anders als beim stationären Einsatz von Feinsprühlöschanlagen, wo die Wasserbeaufschlagung überwiegend flächig von oben oder unten auf einen Brandherd wirkt, wird es beim sachkundigen beweglichen Feuerlöschgeräteeinsatz möglich, den Sprühstrahl direkt auf die Reaktionszone eines Brandes auszurichten. Erst dadurch wird ein hocheffizientes Löschen, insbesondere bei offenen, schnell eskalierenden Bränden, mit relativ geringem Löschwasserbedarf erreicht. Das fein zerstäubte Wasser verfügt mit seiner so enorm vergrößerten Kontaktoberfläche über eine erhöhte Wärmeabsorption, verbunden mit einem temporären Inertisierungseffekt durch Sauerstoffverdrängung infolge akuter Verdampfung. Dadurch sind extrem kurze Löschzeiten möglich. Zwischen dem Ventil und der Feinsprühdüse ist es vorteilhaft, einen flexiblen Schlauch anzuordnen. Als Löschmittel ist es vorteilhaft, eine wäßrige Lösung mit Schaummittel zu verwenden. Weiterhin ist es vorteilhaft, als Treibgas CO2, N2, Ar oder Preßluft einzusetzen. Das Treibmittel kann in einem innen oder außen liegenden Treibgasvorratsbehälter aufbewahrt sein.Advantageously, the fine spray nozzle has a spray angle of at most 30 degrees. This ensures that the resulting fine spray is conveyed at a narrow angle on the fire. The application of fine spray technology is particularly suitable for the mobile sector. Unlike the stationary use of fine spray extinguishing systems, where the application of water predominantly acts surface-to-surface from above or below, the skilled mobile fire extinguisher unit makes it possible to direct the spray jet directly to the reaction zone of a fire. Only then is a highly efficient extinguishing, especially in open, fast escalating fires, achieved with relatively low extinguishing water requirements. The finely atomised water with its enormously enlarged contact surface has increased heat absorption, combined with a temporary inerting effect due to oxygen displacement due to acute evaporation. As a result, extremely short extinguishing times are possible. Between the valve and the fine spray nozzle, it is advantageous to arrange a flexible hose. As extinguishing agent, it is advantageous to use an aqueous solution with foaming agent. Furthermore, it is advantageous to use as propellant CO 2 , N 2 , Ar or compressed air. The propellant may be stored in an internal or external propellant storage tank.

Die Sprühdüsen sind so auszugestalten, daß die maximale Tropfengröße des Feuerlöschmittels 0,1 mm beträgt. Weiterhin ist es vorteilhaft, im Feuerlöschbehälter ein Sieb anzuordnen. Das Treibgas kann mit unterschiedlichen Betriebsdrücken in die Löschflüssigkeit eingebracht werden. Bei Niederdruckgeräten können das bis 16 bar, bei Mitteldruckgeräten sind 16 bis 50 bar denkbar, wobei Hochdruckgeräte mit Drücken oberhalb von 50 bar denkbar sind. Vorteilhaft ist es, einen Startdruck von 30 bar zur Verfügung zu haben.The spray nozzles are to be designed in such a way that the maximum droplet size of the extinguishing agent is 0.1 mm. Furthermore, it is advantageous to arrange a sieve in the fire extinguisher. The propellant gas can be introduced into the extinguishing liquid at different operating pressures. For low-pressure devices, this can be up to 16 bar, for medium-pressure devices 16 to 50 bar are conceivable, with high-pressure devices with pressures above 50 bar being conceivable. It is advantageous to have a starting pressure of 30 bar available.

Im Folgenden wird die Erfindung an drei Figuren und einem Ausführungsbeispiel näher erläutert. Die Figuren zeigen:

Figur 1:
Feinsprühfeuerlöscher mit einem im Löschmittelbehälter angeordneten Druckbehälter.
Figur 2:

Die Figur 1 zeigt einen Feinsprühfeuerlöscher, bestehend aus dem Druckbehälter 1 mit dem wäßrigen Löschmittel 3, welches Wasser darstellt, in das die Löschmittelleitung mit dem Sieb hineinragt, wobei im Löschmittelbehälter 1 ein Druckgasbehälter 2 angeordnet ist, welcher CO2 enthält, so daß Druck am Ventil 5 über die Leitung 9 anliegt. Die Löschdüse 7 stellt eine Sprühdüse dar, deren Sprühwinkel 8 30 Grad beträgt.The FIG. 1 shows a fine spray fire extinguisher, consisting of the pressure vessel 1 with the aqueous extinguishing agent 3, which represents water into which the extinguishing agent pipe protrudes with the sieve, wherein in the extinguishing agent tank 1, a compressed gas container 2 is arranged, which contains CO 2 , so that pressure at the valve 5 via the line 9 is applied. The extinguishing nozzle 7 represents a spray nozzle whose spray angle 8 is 30 degrees.

Die Figur 2 zeigt einen Feuerlöscher 1, an dem ein Druckgasbehälter 2 außen angeordnet ist und zwischen Ventil 5 und Feinsprühdüse 7 eine flexible Leitung 6 angeordnet ist. Der Sprühwinkel 8, der ebenfalls 30 Grad beträgt, dient dazu, den Sprühnebel schnell und flexibel auf dem Brandherd zu verteilen. Der Druck der Löschflüssigkeit beträgt 16 bar. Neben einem schnellen Löschen des Brandes weist der Feuerlöscher den Vorteil auf, daß eine geringe Wassermenge in Form von kleinen Tröpfchen auf dem Brandherd verteilt wird, so daß geringe Wasserschäden entstehen.The FIG. 2 shows a fire extinguisher 1, on which a compressed gas container 2 is arranged on the outside and between valve 5 and fine spray nozzle 7, a flexible conduit 6 is arranged. The spray angle 8, which is also 30 degrees, serves to spread the spray quickly and flexibly on the fire. The pressure of the extinguishing liquid is 16 bar. In addition to a quick extinction of the fire, the fire extinguisher has the advantage that a small amount of water is distributed in the form of small droplets on the fire, so that little water damage.
