Definitions
- the invention relates to a method for deleting an inside of a closed fire preferably inside the cabin or a cargo hold of a passenger plane, the fire being his Maintaining required oxygen by importing Withdrawn nitrogen in the closed room and thus that Fire is extinguished, as well as a device for carrying it out of the procedure.
- DE 36 15 415 C2 a fire extinguishing device with two fire extinguishing agent containers for extinguishing agents that are liquid under excess pressure of a first and second fire-fighting insert for cargo holds of means of transport, in particular of aircraft, described.
- DE 39 17 205 C1 is also a fire-fighting system for airplanes that can be seen in a Aircraft longitudinal direction movable and with a drive device equipped fire extinguishing unit.
- the invention is based on the object of a method of the type mentioned and a device for performing of the process to create a fire suppression in a closed room almost over a unlimited period is made possible.
- the object is thereby achieved solved that after detection of a fire the initial concentration of the inert gas nitrogen within the closed Space is built up suddenly that by the introduction of nitrogen the oxygen content within of the closed room (room oxygen content) to one maximum extinguishing oxygen concentration (maximum concentration) is reduced, and that to maintain the maximum extinguishing oxygen concentration A predetermined amount of nitrogen in the closed room is tracked.
- a further development of the method according to the invention is that the oxygen content within the closed Room (room oxygen content) to about 12 volume percent is reduced.
- Advantageous applications of the invention are in aviation, shipping, rail transport, in structural fire protection, in the military or on other industrial areas, for example in Electronics, freight, equipment, crew, sleeping and conference rooms, Cabins, cockpits and tanks, machine control stations, Bridges, railcars, passenger and freight wagons, Test rooms of universities, museums, theaters, public Buildings, train stations, airports, hotels, department stores, or also in tanks, crew transport vehicles, missile launch bases, Ammunition depots, machine or turbine rooms of power plants.
- the device shown shows two nitrogen gas cylinders 1 and two nitrogen gas generators 2 that over a piping system 3 on inside a closed Room 4 arranged extinguishing nozzles 5 are connected.
- the nitrogen gas cylinders 1 and the nitrogen gas generators 2 with connects the extinguishing nozzles 5 is a flow limiter 7 arranged.
- the flow limiter 7 can be a pressure accumulator 8 for the retention of temporary excess Be upstream of nitrogen.
- the nitrogen gas cylinders are preferably 1 and / or nitrogen gas generators 2 to build up the initial concentration of the inert gas nitrogen depending on the empty volume of the closed room 4 can be triggered simultaneously, the closed space 4 with a pressure compensation system 12 is provided to burst to prevent room 4 from being exposed to gas.
- a device 9 for providing nitrogen in order to maintain the maximum extinguishing oxygen concentration within the closed space 4 is connected to the flow limiter 7 or the pressure accumulator 8.
- the device 9 for providing nitrogen preferably has a membrane system 10 for separating nitrogen from the ambient air, the nitrogen outlet opening of which is connected via a line 11 to the flow rate limiter 7 or pressure accumulator 8.
- the membrane system 10 can separate nitrogen from the air provided by an air conditioning system of a vehicle or aircraft or via a valve from an air outflow channel.

Abstract
Description
- daß Luft zur Generierung des Stickstoffes über Membranen außerhalb des zu inertisierenden Raumes unbegrenzt verfügbar ist,
- daß kein Abbau des stratosphärischen Ozons erfolgt und somit das Verfahren umweltfreundlich ist,
- daß kein Beitrag zum Treibhauseffekt geleistet wird,
- daß keine Schäden an transportierten Gütern oder Raumausstattungen durch das Verfahren entstehen,
- daß das Löschmittel "Stickstoff" in löschwirksamer Konzentration untoxisch gegenüber Mensch und Tier ist, wodurch keine Vorwarnzeiten einzuhalten sowie eine Löschung des Feuers und eine Evakuierung von Personen gleichzeitig möglich sind, und
- daß keine thermischen Zersetzungsprodukte des Stichstoffs unterhalb eines Temperaturbereiches von 1300 bis 1500 C entstehen.
Das Membransystem 10 kann Stickstoff aus der von einer Klimaanlage eines Fahr- oder Flugzeuges bereitgestellten Luft oder über ein Ventil aus einem Luftausströmkanal abscheiden.
