Description
Die Erfindung betrifft ein Löschsystem zur Löschung eines innerhalb eines geschlossenen Raumes ausgebrochenen Feuers, vorzugsweise innerhalb der Kabine oder eines Frachtraumes eines Passagierflugzeuges, wobei eine Einrichtung zur Stickstofferzeugung über ein Rohrleitungssystem mit innerhalb des geschlossenen Raumes angeordneten Löschdüsen in Verbindung steht zwecks Zufuhr von Stickstoff in den geschlossenen Raum, wodurch dem Feuer der zu seiner Aufrechterhaltung erforderliche Sauerstoff entzogen und damit das Feuer gelöscht wird.The invention relates to an extinguishing system for deleting an fire that has broken out inside a closed room, preferably inside the cabin or a cargo hold of a passenger aircraft, a device for nitrogen generation via a piping system with inside the extinguishing nozzles arranged in a closed space is in the closed for the purpose of supplying nitrogen Space, giving the fire what it needs to maintain it Withdrawn oxygen and extinguished the fire becomes.
Im Bereich der Brandbekämpfung in Luftfahrzeugen werden zum heutigen Zeitpunkt alle Raumflutungsanlagen mit dem Löschmittel "Halon 1301" betrieben, während im Bereich des marinen und des baulichen Brandschutzes zumeist Wassersprinkler/sprühdüsen oder Kohlendioxid(CO2)-Löschanlagen eingesetzt werden. Bei industriellen Anwendungen, speziell in Räumen mit empfindlicher Technik wie z.B. Rechneranlagen, wird seit dem Verbot von Halon mittels Kohlendioxid (CO2) gelöscht. In the field of fire fighting in aircraft, all room flooding systems are currently operated with the extinguishing agent "Halon 1301", while in the area of marine and structural fire protection mostly water sprinklers / spray nozzles or carbon dioxide (CO 2 ) extinguishing systems are used. In industrial applications, especially in rooms with sensitive technology such as computer systems, carbon dioxide (CO 2 ) has been used to extinguish halons since the ban.
Ein Löschsystem der eingangs genannten Art ist in der DE-Patentanmeldung 100 51 662.9-22 vorgeschlagen worden. Um bei dieser Anlage eine Brandunterdrückung in dem geschlossenen Raum über einen nahezu unbegrenzten Zeitraum zu ermöglichen, wird nach Detektion eines Feuers die Anfangskonzentration des Inertgases Stickstoff innerhalb des geschlossenen Raumes schlagartig aufgebaut. Durch die Einbringung des Stickstoffes wird der Sauerstoffgehalt innerhalb des geschlossenen Raumes (Raum-Sauerstoffgehalt) auf eine maximal löschwirksame Sauerstoffkonzentration (Maximalkonzentration) herabgesetzt. Zur Aufrechterhaltung der maximal löschwirksamen Sauerstoffkonzentration wird Stickstoff in vorgegebener Menge in den geschlossenen Raum nachgeführt. Vorzugsweise wird der Sauerstoffgehalt innerhalb des geschlossenen Raumes (Raum-Sauerstoffgehalt) auf etwa 12 Volumenprozent herabgesetzt.An extinguishing system of the type mentioned is in the DE patent application 100 51 662.9-22 have been proposed. Around with this system fire suppression in the closed To allow space for an almost unlimited period of time becomes the initial concentration after detection of a fire of the inert gas nitrogen within the closed Suddenly built up space. Through the introduction of nitrogen, the oxygen content within the closed room (room oxygen content) to a maximum extinguishing oxygen concentration (maximum concentration) reduced. To maintain the maximum extinguishing oxygen concentration becomes nitrogen in given amount in the closed room. Preferably the oxygen content is within the closed range Room (room oxygen content) to about 12 volume percent reduced.
Der Erfindung liegt nun die Aufgabe zugrunde, ein Löschsystem zur Löschung eines innerhalb eines geschlossenen Raumes ausgebrochenen Feuers zu schaffen, bei dem unterschiedliche Löschmittel zum Einsatz gelangen.The invention is based on the object of an extinguishing system for deleting an inside a closed space to create a fire that breaks out Extinguishing media are used.
Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß ein Vorratsbehälter zur Speicherung von druckverflüssigtem Halon vorgesehen ist, daß der Vorratsbehälter über das Rohrleitungssystem an die Löschdüsen angeschlossen ist, daß das Halon als erstes, die löschwirksame Konzentration in kurzer Zeit aufbauendes Löschmittel über die Löschdüsen dem geschlossenen Raum zugeführt wird, und daß über die Löschdüsen und das Rohrleitungssystem als zweites Löschmittel stickstoffreiche Luft, welche eine langfristige Feuerunterdrückung sicherstellt, in den geschlossenen Raum eingebracht wird. The object is achieved in that a Storage container for storing pressure-liquefied halon it is provided that the reservoir over the piping system is connected to the extinguishing nozzles that the Halon first, the extinguishing concentration in short Extinguishing agent that builds up time via the extinguishing nozzles closed space is supplied, and that through the extinguishing nozzles and the piping system as a second extinguishing agent nitrogen-rich air, which provides long-term fire suppression ensures brought into the enclosed space becomes.

Durch den Einsatz von Halon bzw. eines adäquaten, geprüften und zugelassenen Ersatzstoffes (z.B. FM200 / FE36) ist es vorteilhafterweise möglich, die löschwirksame Konzentration innerhalb kürzester Zeit aufzubauen. Diese Konzentration ist gegenüber derjenigen von Löschmitteln wie Kohlendioxid, Argon oder Stickstoff sehr gering. Daher wird - während bzw. nachdem sich das Löschmittel gleichmäßig in dem geschlossenen Raum verteilt bzw. verteilt hat - mit der Stickstoffeinleitung in den geschlossenen Raum begonnen und somit vorteilhafterweise eine langfristige Feuerunterdrückung sichergestellt. Das Gemisch im Frachtraum, bestehend aus Halon /Halonersatzstoff und stickstoffreicher Luft, muß zu jedem Zeitpunkt der Unterdrückungsphase über einer bestimmten Minimalkonzentration liegen, wobei das Löschsystem bei vorge-gebener Raumgröße auf diese erforderliche Gemischkonzentration ausgelegt werden muß.Through the use of halon or an adequate, tested and approved substitute (e.g. FM200 / FE36) advantageously the extinguishing concentration set up in no time. This concentration is compared to that of extinguishing agents such as carbon dioxide, argon or nitrogen very low. Therefore - during or after the extinguishing agent is evenly in the closed Distributed or distributed space - with the nitrogen discharge started in the closed space and thus advantageously long-term fire suppression ensured. The mixture in the cargo hold, consisting of halon / halon substitute and nitrogen-rich air, must go to everyone Time of the suppression phase above a certain minimum concentration lie, whereby the extinguishing system at predetermined Room size to this required mixture concentration must be interpreted.
In einem Flugzeug kann beispielsweise bei einem Feuer in einem Frachtraum ein Löschvorgang mit dem erfindungsgemäßen Löschsystem wie folgt durchgeführt werden:
- Branderkennung und Meldung mittels Branddetektionssystem;
- Alarmierung der Cockpit Crew;
- Auslösung der Löschanlage durch die Cockpit Crew;
- Füllung des betroffenen Frachtraumes bis zur festgelegten Designkonzentration mit Halon 1301 oder einem Ersatzstoff;
- Zeitversetztes oder simultanes Auslösen der Stickstoffanlage;
- Beginn der Inertisierung des Frachtraumes mittels Luftseparationsmodul;
- Stetige Zufuhr von stickstoffreicher Luft zur Unterdrükkung bzw. zur Löschung des Feuers bis zur Landung des Flugzeuges und dem Eintreffen der Feuerwehr.
- Fire detection and reporting using a fire detection system;
- Alerting the cockpit crew;
- Triggering of the extinguishing system by the cockpit crew;
- Filling the affected cargo hold up to the specified design concentration with Halon 1301 or a substitute;
- Delayed or simultaneous triggering of the nitrogen system;
- Beginning of inertization of the cargo hold using an air separation module;
- Continuous supply of nitrogen-rich air to suppress or extinguish the fire until the aircraft lands and the fire brigade arrives.
Weitere Vorteile der Erfindung bestehen in der Verwendung von nur gasförmigen Löschmitteln, wodurch eine gute Verteilung innerhalb eines Löschraumes ohne Rückstände und Feuchtigkeit und damit ohne aufwendige Reinigung bei Fehlauslösung sichergestellt wird, sowie in der Gewinnung der Löschmittel während des Betriebes, wodurch sehr lange Unterdrükkungszeiten bei vergleichsweiser geringer Systemmasse realisierbar sind. Wesentliche erfindungsgemäße Vorteile liegen somit in der schnellen Verfügbarkeit des ersten Löschmittels und in der extrem langen Verfügbarkeit des zweiten Löschmittels, da dieses während des Betriebes stetig nachgeliefert werden kann. Die Verwendung von umweltfreundlichen Löschmitteln ist vorteilhaft.Further advantages of the invention are its use of only gaseous extinguishing agents, which ensures a good distribution inside an extinguishing room without residues and moisture and thus without time-consuming cleaning in the event of false triggering is ensured, as well as in the extraction of extinguishing agents during operation, which means very long suppression times feasible with a comparatively small system mass are. Significant advantages according to the invention lie thus the rapid availability of the first extinguishing agent and in the extremely long availability of the second Extinguishing media, as this is constantly supplied during operation can be. The use of environmentally friendly Extinguishing media is advantageous.
In der Zeichnung ist ein Ausführungsbeispiel nach der Erfindung
dargestellt. Die einzige Figur zeigt ein Löschsystem
zur Löschung eines innerhalb eines geschlossenen Raumes 1
ausgebrochenen Feuers. Das System weist einen Vorratsbehälter
2 zur Speicherung von druckverflüssigtem Halon oder eines
Ersatzstoffes auf, wobei der Vorratsbehälter 2 über ein
Rohrleitungssystem 3 an innerhalb des Raumes 1 angeordneten
Löschdüsen 4 angeschlossen ist. Das Halon wird als erstes,
die löschwirksame Konzentration in kurzer Zeit aufbauendes
Löschmittel 5 über die Löschdüsen 4 dem geschlossenen Raum 1
zugeführt. Die zur Feuerlöschung notwendige Designkonzentration
wird durch das massive Einleiten des Halons oder eines
Ersatzstoffes schlagartig aufgebaut. Die Löschmittel greifen
nun je nach ihrem vorwiegenden Löscheffekt in die Verbrennungsreaktion
ein. Der maßgebliche Löscheffekt des Halons
1301 ist die Inhibition in homogener Phase (Entzug von freien
Radikalen aus der Kettenreaktion der Verbrennung). Die
Halonersatzstoffe wirken in der Regel eher sauerstoffverdrängend
und kühlend auf die Verbrennungsreaktion. In the drawing is an embodiment according to the invention
