Description

Die Erfindung betrifft eine Löschanlage für ein kombiniertes Feuerlöschfahrzeug, bestehend aus einem mit einem Löschpulver gefüllten Behälter, der über eine Aufladeleitung, mittels eines in gesonderten Hochdruckbehältern abgefüllten Treibgases hohen Druckes unter Druck gesetzt ist, wobei ein oder mehrere Verbraucher mit dem Behälter verbunden sind.The invention relates to an extinguishing system for a combined fire-fighting vehicle, consisting of a container filled with an extinguishing powder, which is pressurized via a charging line by means of a high-pressure propellant gas filled in separate high-pressure containers, one or more consumers being connected to the container.

Pulverlöschanlagen arbeiten nach dem Trockenlösch-Verfahren, mit feinkörnigem Trockenlöschpulver, das unter Druck von Stickstoff oder dergleichen über Schläuche mit angeschlossenen Löschpistolen oder über einen Pulverwerfer ausgespritzt wird. Dabei entwickelt sich eine dichte, mit zunehmenden Abstand von der Löschpistole oder dem Pulverwerfer großräumiger werdende Löschwolke, mit der sich ein Brandherd umhüllen und das Feuer schlagartig ersticken läßt.Powder extinguishing systems work according to the dry extinguishing process, with fine-grained dry extinguishing powder which is sprayed out under pressure from nitrogen or the like via hoses with connected extinguishing guns or via a powder launcher. This creates a dense cloud of extinguishing cloud, which becomes larger as the distance from the extinguishing gun or the powder launcher increases, with which a source of fire can be enveloped and the fire suddenly suffocated.

Um einen Löschpulverfluß zu ermöglichen, muß das Löschpulver in den Pulverbehältern mit einem Druckgas durchsetzt werden. Hierzu werden beispielsweise Stickstofflaschen oder Stickstoffbatterien verwendet, die einen Fülldruck von 200 bar aufweisen.To enable an extinguishing powder flow, the extinguishing powder in the powder containers must be mixed with a compressed gas. For this purpose, nitrogen bottles or nitrogen batteries are used, for example, which have a filling pressure of 200 bar.

Es ist bekannt (DE-OS 23 35 680), derartige Pulverlösch-Anlagen als schnellwirkendes Löschverfahren zur Bekämpfung von Bränden im Außenbereich auf Löschfahrzeugen einzusetzen. Hier wird der Pulverbehälter über eine Speiseleitung mit einem Reduzierventil mit dem Druckgas beaufschlagt.It is known (DE-OS 23 35 680) to use such powder extinguishing systems as a fast-acting extinguishing method for fighting fires in the outside area on fire trucks. Here the powder container is pressurized with the compressed gas via a feed line with a reducing valve.

Es sind auch Löschanlagen bekannt, die zur Bekämpfung von Brandherden in Räumen, z.B. Labors, Computer-Räumen, EDV-Anlagen, usw., mit einem Löschgas eingesetzt werden. Als gasförmige Löschmittel haben sich besonders unter Druck verflüssigtes Kohlendioxid (C02), unter Druck verflüssigte Halogen-Kohlenwasserstoffe, wie Halon 1211 oder 1301 durchgesetzt. Das Löschgas ist in Gasflaschen abgefüllt und wird zu Löschgasbatterien zusammengefaßt.Extinguishing systems are also known which are used to combat fire sources in rooms, e.g. Laboratories, computer rooms, computer systems, etc., can be used with an extinguishing gas. Carbon dioxide (C02) liquefied under pressure, halogen hydrocarbons liquefied under pressure, such as Halon 1211 or 1301, have established themselves as gaseous extinguishing agents. The extinguishing gas is filled into gas bottles and is combined into extinguishing gas batteries.

Es ist bekannt, Gaslösch-Anlagen auch auf Löschfahrzeugen vorzusehen.It is known to provide gas extinguishing systems on fire trucks as well.

Werden die Pulverlösch-Anlagen und die Gaslösch-Anlagen auf einem Löschfahrzeug vereinigt, dann ergeben sich durch die kombinierte Anlage hohe Gewichte, weil die Pulveranlagen im Einsatzfalle aus ebenfalls auf dem Fahrzeug mitgeführten Stickstoff-Flaschenbatterien mit Treibgas versorgt werden müssen. Die hierdurch bedingten Gewichte machen sich insbesondere bei Feuerlöschfahrzeuggen ungünstig bemerkbar. Fahrzeuge haben ein zulässiges Gesamtgewicht. Sind die Anlagenteile sehr schwer, dann kann nur eine geringe Menge an Löschmittel aufgenommen werden.If the powder extinguishing systems and the gas extinguishing systems are combined on a fire truck, the combined system results in high weights because the powder systems have to be supplied with propellant gas from nitrogen cylinder batteries that are also carried on the vehicle. The resulting weights are particularly noticeable in fire engines. Vehicles have a permissible total weight. If the system parts are very heavy, only a small amount of extinguishing agent can be absorbed.

Der Erfindung liegt die Aufgabe zugrunde, insbesondere für Feuerlöschfahrzeuge eine Löschanlage zu schaffen, die leichter, platz sparender und kostengünstiger ist und somit eine optimalere Auslastung des Fahrzeuges ermöglicht.The invention has for its object, in particular for fire-fighting vehicles to provide an extinguishing system which is lighter, space-saving and less expensive and thus enables more optimal utilization of the vehicle.

Diese Aufgabe wird dadurch gelöst, daß die Löschanlage als kombinierte Pulver- und Gaslösch-Anlage über getrennte Verbraucher verwendet wird, wobei das Hochdruckgas ein Löschgas ist, das zur Aufladung der Pulveranlage und zur Löschung von Bränden eingesetzt wird, und daß das Hochdruckgas im Einsatzfalle mittels einer Druckreduzierung in der Aufladeleitung dem Pulverbehälter zugeführt wird.This object is achieved in that the extinguishing system is used as a combined powder and gas extinguishing system via separate consumers, the high pressure gas being an extinguishing gas which is used for charging the powder system and for extinguishing fires, and in that the high pressure gas in the event of use a pressure reduction in the charging line is fed to the powder container.

Mit dieser Maßnahme wird das zur Förderung des Pulvers erforderliche Treibgas durch das Löschgas ersetzt, so daß die Stickstoff-Flaschenbatterien entfallen und sich dadurch das Fahrzeuggewicht reduziert.With this measure, the propellant gas required for conveying the powder is replaced by the extinguishing gas, so that the nitrogen cylinder batteries are eliminated and the vehicle weight is thereby reduced.

Gleichzeitig kann aufgrund des verminderten Druckes des Treibgases das Gewicht des Pulverbehälters vermindert werden, was zu einer weiteren Reduzierung des Fahrzeuggewichtes führt.At the same time, the weight of the powder container can be reduced due to the reduced pressure of the propellant gas, which leads to a further reduction in the weight of the vehicle.

Als Treib- und Löschgas kann C02 oder Halon 1301 verwendet werden. Eine vorzugsweise Ausgestaltung der Erfindung besteht darin, daß in der Aufladeleitung zwischen der Druckreduzierung und der Hochdruckflasche ein Absperrorgan vorgesehen ist, und daß zwischen dem Absperrorgan und der Hochdruckflasche ein mit einem Absperrventil versehene Zweigleitung abgeht, die über eine Schlauchleitung in einem Schneerohr oder einem anderen Verbraucher endet.C02 or Halon 1301 can be used as propellant and extinguishing gas. A preferred embodiment of the invention is that a shut-off device is provided in the charging line between the pressure reduction and the high-pressure bottle, and that a branch line provided with a shut-off valve goes out between the shut-off device and the high-pressure bottle, which branches off via a hose line in a snow pipe or another consumer ends.

Dabei kann das Absperrorgan als Kugelhahnventil ausgebildet sein, von dem die mit dem Druckminderer versehene Aufladeleitung weitergeführt ist.The shut-off device can be designed as a ball valve from which the charging line provided with the pressure reducer is continued.

Die Löschanlage 16 besteht im wesentlichen aus der Pulverlösch-Anlage 16a und der Gaslösch-Anlage 16b. Beide Anlagen werden gemeinsam aus einer Hochdruckflasche 2 oder einer Gasflaschenbatterie mit Druckgas versorgt. Die Pulverlösch-Anlage 16a ist im Ausführungsbeispiel mit drei Verbrauchern 18, 19 und 20 ausgerüstet, nämlich einem Werferrohr 18 und zwei Schlauchleitungen 19 und 20. Der Behälter 1 ist mit dem Löschpulver 28 gefüllt. Von der Hochdruckflasche 2 geht eine Aufladeleitung 17 in den Behälter 1. In der Aufladeleitung 17 befindet sich eine Druckreduzierung 23, die aus einem Niederdruckregler 5, einem Hochdruckregler 3 und einem dazwischen geschalteten Druckminderer 4 besteht, wobei dieser Druckminderer über Leitungen 24 und 25 einerseits mit der Aufladeleitung 17 und andererseits mit dem Niederdruckregler 5 verbunden ist. Fernerhin ist in der Leitung 17 ein Rückschlagventil 6 vorgesehen. Im Ausführungsbeispiel sind zwei Entnahmerohre 21 und 22 vorgesehen, wobei an dem Entnahmerohr 22 über ein Absperrventil 9 ein Werferrohr 18 angeordnet ist. An dem Entnahmerohr 22 sind über Ventile 10 und 11 Schlauchleitungen 19 und 20 vorgesehen. Für die zusätzliche Gaszufuhr in das Werferrohr 18 ist eine Leitung 15 vorgesehen, die zwischen dem Rückschlagventil 6 und dem Niederdruckregler 5 mit der Aufladeleitung 17 verbunden ist und in das untere Ende des abgewinkelten Entnahmerohres 21 eingeführt ist. Zur Spülung der Verbraucher 19 bis 20 ist eine Spülleitung 26 angeordnet, die im oberen Bereich in den Behälter 1 geführt ist und dort ein Staubfilter 27 aufweist. Über Zweigleitungen 26a und 26b sind weitere Leitungen vorgesehen, in denen sich Spülventile 12, 13 und 14 befinden. Zur Überwachung der Anlage ist ein Betriebsdruckmanometer 8 und ein Sicherheitsventil 7 im Behälter 1 vorgesehen.The extinguishing system 16 essentially consists of the powder extinguishing system 16a and the gas extinguishing system 16b. Both systems are supplied with compressed gas from a high-pressure bottle 2 or a gas bottle battery. In the exemplary embodiment, the powder extinguishing system 16a is equipped with three consumers 18, 19 and 20, namely a launcher tube 18 and two hose lines 19 and 20. The container 1 is filled with the extinguishing powder 28. From the high-pressure bottle 2, a charging line 17 goes into the container 1. In the charging line 17 there is a pressure reduction 23, which consists of a low-pressure regulator 5, a high-pressure regulator 3 and a pressure reducer 4 connected in between, this pressure reducer also being connected via lines 24 and 25 the charging line 17 and on the other hand is connected to the low pressure regulator 5. Furthermore, a check valve 6 is provided in line 17. In the exemplary embodiment, two extraction tubes 21 and 22 are provided, a launcher tube 18 being arranged on the extraction tube 22 via a shut-off valve 9. Hose lines 19 and 20 are provided on the extraction pipe 22 via valves 10 and 11. For the additional gas supply into the launcher tube 18, a line 15 is provided, which is connected between the check valve 6 and the low pressure regulator 5 to the charging line 17 and is inserted into the lower end of the angled extraction tube 21. To flush the consumer is 19 to 20 a flushing line 26 is arranged, which is guided in the upper region into the container 1 and has a dust filter 27 there. Additional lines are provided via branch lines 26a and 26b, in which flushing valves 12, 13 and 14 are located. To monitor the system, an operating pressure manometer 8 and a safety valve 7 are provided in the container 1.

Für die Gaslösch-Anlage 16b ist bei 36 von der Aufladeleitung 17 eine Zweigleitung 29 abgeführt, wobei hinter der Abzweigung 36 in der Aufladeleitung 17 ein Absperrorgan 30 und in der Zweigleitung 29 ein Absperrventil 31 vorgesehen ist. Die Leitung 29 ist zu einer Schlauchhaspel 32 geführt, auf der eine Schlauchleitung 33 aufgewickelt ist, die über ein Ventil 34 zu einem Schneerohr 35 geführt ist.For the gas extinguishing system 16b, a branch line 29 is discharged from the charging line 17 at 36, a shutoff element 30 being provided behind the branch 36 in the charging line 17 and a shutoff valve 31 in the branch line 29. The line 29 is guided to a hose reel 32, on which a hose line 33 is wound, which is guided via a valve 34 to a snow pipe 35.

Fig. 2 zeigt eine weitere Ausgestaltung der Erfindung. Hier ist eine Gasflaschenbatterie mit den Flaschen 2a und 2b dargestellt, ist. Selbstverständlich können auch mehr als zwei Gasflaschen für eine Batterie vorgesehen sein. Des weiteren ist in diesem Ausführungsbeispiel das Absperrorgan als Kugelhahnventil 30a ausgebildet, von dem eine Zweigleitung 17a zu dem Behälter 1 geführt ist. In der Leitung 17a befindet sich der Druckminderer 23a und ein Überströmventil 37. Außerdem ist eine Umführleitung 39 mit einem Rückschlagventil 38 vorgesehen. Des weiteren ist zwischen dem Ventil 30a und dem Behälter 1 eine Leitung 40 vorgesehen, in die ein Rückschlagventil 41 und ein Drucksteuergerät 42 vorgesehen ist. Ist beispielsweise in den Hochdruckflaschen 2a und 2b ein verflüssigtes Gas gelagert und gelangt dieses verflüssigte Gas über den Druckminderer 23a in den Behälter 1, so ist hiermit eine Ausdampfung des Flüssiggases verbunden, was sich andererseits in einem erhöhten Druck innerhalb des Behälters 1 bemerkbar macht. Das Drucksteuergerät 42 sorgt in diesem Falle für einen konstanten Druck innerhalb des Behälters 1, wobei das Kugelhahnventil 30a entsprechend gesteuert wird.Fig. 2 shows a further embodiment of the invention. Here is a gas bottle battery with the bottles 2a and 2b is shown. Of course, more than two gas bottles can also be provided for a battery. Furthermore, in this exemplary embodiment, the shut-off element is designed as a ball valve 30a, from which a branch line 17a is led to the container 1. The pressure reducer 23a and an overflow valve 37 are located in the line 17a. In addition, a bypass line 39 with a check valve 38 is provided. Furthermore, a line 40 is provided between the valve 30a and the container 1, into which a check valve 41 and a pressure control device 42 is provided. If, for example, a liquefied gas is stored in the high-pressure bottles 2a and 2b and this liquefied gas reaches the container 1 via the pressure reducer 23a, this results in an evaporation of the liquid gas, which is noticeable on the other hand in an increased pressure inside the container 1. In this case, the pressure control device 42 ensures a constant pressure within the container 1, the ball valve 30a being controlled accordingly.
