To render possible targeted pressurization with either extinguishing fluid or extinguishing gas, the invention proposes that optionally only the extinguishing fluid container 2 or only the extinguishing gas nozzle 6 is pressurized with propellant via the joint propellant supply 8.

Description

Die Erfindung betrifft im allgemeinen ein Verfahren und eine Vorrichtung zur Brandbekämpfung.The invention generally relates to a method and apparatus for fire fighting.

Heutzutage ist es bekannt, Brände in Räumen mit Hilfe von Feinstnebeln zu löschen. Hierbei werden unter hohen Drücken Löschfluide, beispielsweise Wasser oder mit Additiven versetztes Wasser, aus Löschnebeldüsen ausgebracht. Bei Drücken von 100bar und mehr erzeugen die Löschnebeldüsen einen fein verteilten Löschnebel, der gute Löscheigenschaften hat, da dieser den Brandherd gut kühlt und das Feuer somit gut löscht.Today it is known to extinguish fires in rooms with the help of fine nebulas. In this case, extinguishing fluids, for example water or water added with additives, are discharged from extinguishing mist nozzles at high pressures. At pressures of 100bar and more, the extinguishing spray nozzles produce a finely dispersed extinguishing mist, which has good extinguishing properties, since it cools the fire well and thus extinguishes the fire well.

Es hat sich jedoch gezeigt, dass nicht alle Brandherde mit Hilfe solcher Löschnebel gut gelöscht werden können. Beispielsweise lassen sich Brände in Räumen mit schwer zugänglichen Ecken und kleinen Volumina besser mit Löschgas als mit Löschnebel löschen. So ist beispielsweise aus der DE 694 22 926 T3 bekannt, Flüssigkeitsnebel in einen Hauptbereich eines gesamten zu löschenden Raums mittels Sprühköpfen auszubringen und zusätzlich zu dem Versprühen des Flüssigkeitsnebels lokal innerhalb eines Bereiches im zu löschenden Raum Gas zu versprühen. Das Volumen des Bereiches, in dem Gas versprüht wird, ist eng innerhalb des Gesamtvolumens umgrenzt.However, it has been shown that not all fires can be well erased with the help of such extinguishing mist. For example, fires in rooms with hard-to-reach corners and small volumes can be better extinguished with extinguishing gas than with extinguishing mist. For example, from the DE 694 22 926 T3 It is known to apply liquid mist to a main area of an entire space to be extinguished by means of spray heads and to spray gas in addition to spraying the liquid mist locally within a range in the space to be extinguished. The volume of the area in which gas is sprayed is closely circumscribed within the total volume.

Bei dem aus dieser Druckschrift bekannten Verfahren ist es jedoch von Nachteil, dass eine Vermengung von Löschfluid und Löschgas nicht verhindert werden kann. Beispielsweise kann durch diese bekannte Vorrichtung nicht verhindert werden, dass in sensiblen Bereichen, in denen ausschließlich Löschgas verwendet werden sollte, Löschfluid eingebracht wird. Andererseits kann nicht verhindert werden, dass in einem Raum, der ausschließlich mit Löschfluid gelöscht werden soll, Löschgas eingebracht wird. Die beschriebene Ventilanordnung eignet sich nicht zur wahlweisen Beaufschlagung entweder mit Löschnebel oder Löschgas.In the method known from this document, however, it is disadvantageous that a mixing of extinguishing fluid and quenching gas can not be prevented. For example, it can not be prevented by this known device that in sensitive areas, in which only quenching gas should be used, quenching fluid is introduced. On the other hand, can not be prevented that in a room to be extinguished exclusively with extinguishing fluid, quenching gas is introduced. The described valve arrangement is not suitable for the selective admission either with extinguishing mist or extinguishing gas.

Aus der US 2002/139542 A1 ist bekannt, einen detektierten Brand in zwei Phasen zu löschen, wobei in einer ersten Phase Wasser als Löschmedium ausgebracht wird und in einer zweiten Phase ein Inertgas.From the US 2002/139542 A1 It is known to extinguish a detected fire in two phases, wherein in a first phase, water is discharged as extinguishing medium and in a second phase, an inert gas.

Der Erfindung lag die Aufgabe zugrunde, eine Brandbekämpfung zur Verfügung zu stellen, die zum einen geringe technische Anforderungen stellt und zum anderen eine hohe Sicherheit gewährleistet.The invention had the object of providing a fire fighting available, which provides low technical requirements and on the other hand ensures a high level of security.

Diese Aufgabe wird gemäß eines Gegenstandes durch ein Verfahren zur Brandbekämpfung nach Anspruch 1 gelöst.This object is achieved according to an article by a fire fighting method according to claim 1.

Es ist erkannt worden, dass eine gemeinsame Treibgasversorgung für Löschfluidbehälter und Löschgasdüse nur geringe technische Anforderungen stellt. So ist die Bereitstellung des Treibgases durch eine gemeinsame Treibgasversorgung, beispielsweise eine Druckgasflasche, leicht zu realisieren. Beispielsweise kann dies innerhalb von Zügen oder auch anderen mobilen Systemen ohne weiteres realisiert werden. Es ist nicht mehr notwendig, unterschiedliche Treibgasversorgungen für das Löschen mit Löschgas und für das Löschen mit Löschnebel bereitzuhalten. Es ist ferner erkannt worden, dass es aufgrund von Sicherheitsvorschriften in vielen Fällen vermieden werden muss, dass in Räume, die mit Löschfluid gelöscht werden, Löschgas eindringt. Andererseits sind Räume, die beispielsweise mit technischen Einrichtungen bestückt sind, empfindlich gegenüber Wasser, so dass hier ausschließlich mit Löschgas gelöscht werden sollte. Daher schlägt die Erfindung vor, dass entweder der Löschfluidbehälter oder die Löschgasdüse über die gemeinsame Treibgasversorgung mit Treibgas beaufschlagt wird. Das bedeutet, dass die gemeinsame Treibgasversorgung dazu genutzt wird, entweder Löschnebel in einem dafür vorgesehenen Raum durch Löschnebeldüsen, oder Löschgas in einem dafür vorgesehenen Raum durch Löschgasdüsen auszubringen. Eine Vermengung von Löschfluid und Treibgas wird verhindert. Bevorzugt ist das Treibgas ein Löschgas.It has been recognized that a common propellant gas supply for extinguishing fluid container and quenching gas nozzle provides only low technical requirements. Thus, the provision of the propellant gas by a common propellant gas supply, such as a compressed gas cylinder, is easy to implement. For example This can be easily realized within trains or other mobile systems. It is no longer necessary to provide different propellant gas supplies for extinguishing with quenching gas and extinguishing with extinguishing mist. It has also been recognized that, due to safety regulations, in many cases it must be avoided that quenching gas penetrates into spaces that are extinguished with extinguishing fluid. On the other hand, rooms that are equipped, for example, with technical facilities, sensitive to water, so that should be deleted here exclusively with extinguishing gas. Therefore, the invention proposes that either the extinguishing fluid container or the extinguishing gas nozzle is acted upon by the common propellant gas supply with propellant gas. This means that the common propellant gas supply is used to either extinguishing mist in a space provided by Löschnebeldüsen, or fire extinguishing gas in a space provided by extinguishing gas nozzles. Mixing of extinguishing fluid and propellant gas is prevented. The propellant gas is preferably an extinguishing gas.

Die wahlweise Beaufschlagung des Löschfluidbehälters oder der Löschgasdüse wird über ein Ventil gesteuert. Das Ventil ist hierbei bevorzugt zwischen der Treibmittelversorgung und dem Löschmittelbehälter bzw. den Löschgasdüsen angeordnet. Beispielsweise kann das Ventil an einer Abzweigung in einer Rohrleitung angeordnet werden. Eine erste Abzweigung führt zum Löschmittelbehälter und eine zweite Abzweigung führt zur Löschgasdüse. Das Ventil kann über Steuermittel angesteuert werden. Diese können die wahlweise Beschickung des Löschmittelbehälters bzw. der Löschgasdüse mit Treibgas steuern. Das Ventil ist dabei bevorzugt ein Drehventil. Eine Steuerung über Stellmotoren ist möglich. Die Stellmotoren werden mittels einer geeigneten Steuerung angesteuert und bevorzugt von voneinander unabhängig agierenden Brandmeldern, die in verschiedenen Räumen angeordnet sind, ausgelöst.The selective loading of the extinguishing fluid container or the quenching gas nozzle is controlled by a valve. The valve is preferably arranged between the propellant supply and the extinguishing agent container or the extinguishing gas nozzles. For example, the valve can be arranged at a branch in a pipeline. A first branch leads to the extinguishing agent tank and a second branch leads to the extinguishing gas nozzle. The valve can via control means be controlled. These can control the optional charging of the extinguishing agent container or the extinguishing gas nozzle with propellant gas. The valve is preferably a rotary valve. Control via servo motors is possible. The servomotors are controlled by a suitable controller and preferably triggered by independently acting fire detectors, which are arranged in different rooms.

Bevorzugt ist jeweils ein Brandmelder in einem Raum, in dem Löschnebeldüsen vorgesehen sind und in einem Raum, in dem Löschgasdüsen vorgesehen sind, angeordnet.In each case, a fire detector is preferably arranged in a room in which extinguishing mist nozzles are provided and arranged in a space in which extinguishing gas nozzles are provided.

Diese Räume sind bevorzugt voneinander getrennt. Beispielsweise können dies ein Triebwagen innerhalb eines Zuges und ein Fahrgastraum sein. Innerhalb des Triebwagens muss verhindert werden, dass die Fahrzeugtechnik mit Löschfluid in Berührung kommt. Daher ist hier ein Löschen mit Löschgas bevorzugt. Im Fahrgastraum sollte vermieden werden, dass sich Löschgas in den Löschnebel mischt, da dieses häufig gesundheitsgefährdend ist.These spaces are preferably separated from each other. For example, this may be a railcar within a train and a passenger compartment. Within the railcar, it must be prevented that the vehicle technology comes into contact with extinguishing fluid. Therefore, extinguishing with extinguishing gas is preferred here. In the passenger compartment, it should be avoided that extinguishing gas mixes into the extinguishing mist, as this is often hazardous to health.

Gemäß eines vorteilhaften Ausführungsbeispiels ist das Treibmittel ausgewählt aus der Gruppe aus Inertgas, Stickstoff, Kohlendioxid, Argon, Halon, oder Kombinationen daraus.According to an advantageous embodiment, the propellant is selected from the group consisting of inert gas, nitrogen, carbon dioxide, argon, halon, or combinations thereof.

Ein weiterer Gegenstand betrifft eine Brandbekämpfungsvorrichtung nach Anspruch 3.Another subject matter relates to a fire fighting apparatus according to claim 3.

Weitere Vorteile ergeben sich aus den nachgeordneten Ansprüchen. Nachfolgend wird die Erfindung anhand einer ein Ausführungsbeispiel zeigenden Zeichnung näher erläutert. In der Zeichnung zeigt die einzige Figur eine Brandbekämpfungsvorrichtung.Further advantages emerge from the subordinate claims. The invention will be explained in more detail with reference to a drawing showing an embodiment. In the drawing, the single figure shows a firefighting device.

Gezeigt ist ein Löschfluidbehälter 2, Löschnebeldüsen 4, eine Löschgasdüse 6, eine Treibmittelversorgung 8, ein Ventil 10, Brandmelder 12 und 14 und ein Stellmotor 20. Der Brandmelder 12 ist zusammen mit den Löschnebeldüsen 4 in einem Fahrgastraum 16 angeordnet. Der Brandmelder 14 ist zusammen mit der Löschgasdüse 6 in einem Triebwerk 18 angeordnet. Die gezeigte Anordnung arbeitet wie folgt:Shown is an extinguishing fluid container 2, Löschnebeldüsen 4, a quenching gas nozzle 6, a propellant supply 8, a valve 10, fire detectors 12 and 14 and a servomotor 20. The fire detector 12 is arranged together with the Löschnebeldüsen 4 in a passenger compartment 16. The fire detector 14 is arranged together with the extinguishing gas nozzle 6 in an engine 18. The arrangement shown operates as follows:

Die Treibgasversorgung 8 ist durch eine Druckgasflasche gebildet. In der Druckgasflasche ist ein Löschgas unter hohem Druck gespeichert. Das Ventil 10 ist in der Ruhestellung so eingestellt, dass die Treibgasversorgung 8 gegenüber der weiteren Rohrleitung verschlossen ist.The propellant gas supply 8 is formed by a compressed gas cylinder. In the compressed gas cylinder, a quenching gas is stored under high pressure. The valve 10 is set in the rest position so that the propellant gas supply 8 is closed relative to the other pipeline.

Im Fall eines Brandes in dem Fahrgastraum 16 löst der Brandmelder 12 einen Impuls aus, der den Stellmotor 20 ansteuert. Der Stellmotor 20 stellt das Ventil 10 so ein, dass eine Verbindung zwischen Treibgasversorgung 8 und Löschmittelbehälter 2 hergestellt wird. Treibgas strömt aus der Treibgasversorgung 8 in den Löschfluidbehälter 2 und treibt darin gelagertes Löschfluid über eine Rohrleitung in die Löschnebeldüsen 4. Durch den hohen Druck, mit dem das Treibgas in den Löschfluidbehälter 2 eindringt, wird dieses aus dem Löschfluidbehälter gedrückt und liegt mit einem hohen Druck an den Löschnebeldüsen 4 an. Hierdurch wird ein feinverteilter Nebel in den Fahrgastraum 16 ausgebracht. Der Löschnebel löscht den Brand und der Brandmelder 12 meldet dies an den Stellmotor 20, der daraufhin das Ventil 10 wieder in die geschlossene Position verstellt.In the event of a fire in the passenger compartment 16, the fire detector 12 triggers a pulse that drives the servomotor 20. The servomotor 20 adjusts the valve 10 so that a connection between propellant gas supply 8 and extinguishing agent container 2 is produced. Propellant gas flows from the propellant gas supply 8 into the extinguishing fluid container 2 and drives therein stored extinguishing fluid via a pipeline into the extinguishing mist nozzles 4. The high pressure with which the propellant gas enters the extinguishing fluid container 2, this is pressed from the extinguishing fluid container and is at a high pressure on the Löschnebeldüsen 4 at. This will be a finely divided Fog deployed in the passenger compartment 16. The extinguishing mist extinguishes the fire and the fire detector 12 reports this to the servomotor 20, which then adjusts the valve 10 again in the closed position.

Über eine in dem Löschfluidbehälter 2 angeordnete Detektorschaltung wird detektiert, falls kein weiteres Löschfluid mehr in dem Löschfluidbehälter 2 vorhanden ist. In diesem Falle sperrt diese Anordnung die Verbindung zwischen Löschfluidbehälter 2 und Treibgasversorgung 8, so dass kein Treibgas in die Rohrleitung und die Löschnebeldüsen 4 und somit in den Fahrgastraum 16 eindringen kann.A detector circuit arranged in the extinguishing fluid container 2 is detected if no further extinguishing fluid is present in the extinguishing fluid container 2. In this case, this arrangement blocks the connection between extinguishing fluid container 2 and propellant gas supply 8, so that no propellant gas can penetrate into the pipeline and the extinguishing mist nozzles 4 and thus into the passenger compartment 16.

Im Falle eines Brandes im Triebwerk 18 löst der Brandmelder 14 einen Impuls aus, der den Stellmotor 20 dazu veranlasst, das Ventil derart zu verstellen, dass eine Verbindung zwischen Treibgasversorgung 8 und Löschgasdüse 6 hergestellt ist. Treibgas kann aus der Treibgasversorgung 8 in die Löschgasdüse 6 eindringen und sich in dem Triebwerkraum 18 verteilen. Hierdurch wird der Brand in dem Triebwerkraum 18 gelöscht. Nachdem der Brand gelöscht wurde, meldet der Brandmelder 14 dies an den Stellmotor 20, der daraufhin das Ventil wieder schließt.In the event of a fire in the engine 18, the fire detector 14 triggers a pulse that causes the servomotor 20 to adjust the valve so that a connection between propellant gas supply 8 and quenching gas nozzle 6 is made. Propellant gas can enter the quenching gas nozzle 6 from the propellant gas supply 8 and distribute itself in the engine compartment 18. As a result, the fire in the engine compartment 18 is deleted. After the fire has been extinguished, the fire detector 14 reports this to the servomotor 20, which then closes the valve again.

Die gezeigte Anordnung ermöglicht es, voneinander getrennte Räume gezielt über eine gemeinsame Treibgasversorgung entweder mit Löschfluid oder Löschgas zu versorgen. Eine Vermengung von Löschfluid und Löschgas wird vermieden, so dass hohe Sicherheitsanforderungen erfüllt werden.The arrangement shown makes it possible to supply separate rooms selectively via a common propellant gas supply either with extinguishing fluid or quenching gas. A mixture of extinguishing fluid and quenching gas is avoided, so that high safety requirements are met.
