Abstract
Description
Technisches GebietTechnical area
Bei der erfindungsgemäßen Vorrichtung handelt es sich um eine spezifische Sprühdüse (sogenannte Sprinkler) zur Verteilung von vorzugsweise Löschwasser über einem Brandherd beispielsweise in Gebäuden.at the device of the invention is it is a specific spray nozzle (so-called Sprinkler) for the distribution of preferably extinguishing water over a fire, for example, in Buildings.
Derartige Brandlöschsysteme sind aus dem einschlägigen Stand der Technik hinlänglich bekannt und langjährig praxisbewährt als sogenannte Sprinkleranlagen.such Fire extinguishing systems are from the relevant State of the art known and longtime proven in practice as so-called sprinkler systems.
Ebenso bekannt wie bewährt sind die den Löschvorgang auslösenden Sprühdüsen – sogenannte Sprinkler.As well known as proven are the deletion process triggering Spray nozzles - so-called Sprinkler.
Letztere sind in spezifischen Abständen über einer zu schützenden Raumfläche – in der Regel an der Decke (Dach) – angeordnet und mit einem unter Wasserdruck stehendem Rohrleitungssystem verbunden.Latter are at specific intervals above one to be protected Room area - in the Usually on the ceiling (roof) - arranged and connected to a pressurized piping system.
Im aktiven Einsatzfall (Entstehungsbrand im geschützten Bereich) erfolgt Auslösung der Sprinkler durch die Wärmeentwicklung. Hierbei zerspringt eine wärmeempfindliche, das Löschwasser im passiven Zustand zurückhaltende, Absperrung (in der Regel ein Glasfass) – das Löschwasser wird frei und der Löschvorgang eingeleitet.in the active application (emergence fire in the protected area) is triggered by the Sprinklers by the heat development. This shatters a heat-sensitive, the extinguishing water restrained in the passive state, Shut-off (usually a glass keg) - the extinguishing water is released and the extinguishing process initiated.
Hierbei strömt das Löschwasser unter hohem Druck durch die Sprinklerdüse auf den Sprühteller des Sprinklers und verteilt sich entsprechend den Konturen des Sprühtellers in der Art eines Wasserschirmes über den Brandherd – der primäre Löschvorgang wird eingeleitet und im spezifischen Zeitfaktor (bestimmungsgemäß) abgeschlossen.in this connection flows the extinguishing water under high pressure through the sprinkler nozzle on the spray plate of the sprinkler and distributed according to the contours of the spray plate in the manner of a water umbrella over the fire - the primary deletion is initiated and completed in the specific time factor (as intended).
Darstellung der ErfindungPresentation of the invention
Aufgabe der Erfindung ist eine wesentliche Verbesserung der Löschwirkung der konventionellen Sprinklerbrandlöschtechnik im Verbund mit rationalerer Anlagentechnik.task The invention is a significant improvement of the extinguishing effect the conventional sprinkler fire extinguishing technology combined with more rational Systems engineering.
Im
Beispiel:
Ist einem konventionellen Sprinkler eine Wirkfläche (zu
schützende
Raumfläche)
bei einer zur Verfügung gestellten
Wassermenge „X" von ca. 10 m2 zugeordnet, ist das Ziel der Erfindung
einerseits:
- - bei gleicher Wassermenge („X") eine größere Wirkfläche verfügbar zu machen – beispielsweise 12–15 m2
- bei gleicher Wirkfläche eine deutliche Reduzierung der Wassermenge („X") zu ermöglichen.
If an effective area (area of space to be protected) is allocated to a conventional sprinkler with an available quantity of water "X" of approximately 10 m 2 , the aim of the invention is on the one hand:
- - For the same amount of water ("X") to make a larger effective area available - for example, 12-15 m 2
- to allow a significant reduction in the amount of water ("X") for the same effective area.
Diese Vorteile werden in einfacher Form dadurch erreicht, dass die konventionelle Wasserdüse des Sprinklers als sogenannte Injektor-Düse ausgebildet wird.These Advantages are achieved in a simple form in that the conventional Water nozzle of the Sprinklers is designed as a so-called injector nozzle.
Das aus dem Stand der Technik bekannte Injektorprinzip bewirkt, dass dem Löschwasser in vorbestimmbarem Anteil Luft beigemischt werden kann. Hierbei erfolgt eine homogene Mischung von Wasser und Luft – prinzipiell eine Volumenerhöhung des Löschmittels (Wasser und Luft) – hierdurch eine Reduzierung der Durchmesser der über eine spezifische Druckdüse oder über einen spezifischen den Sprühteller des Sprinklers hergestellten Wassertropfen. In einfacher Logik: „Kleinere Wassertropfen in größerer Anzahl" ergeben eine Steigerung der Löschwirkung (ein praxisbestätigter Effekt).The known from the prior art injector principle causes the extinguishing water Air can be added in a predeterminable proportion. in this connection a homogeneous mixture of water and air takes place - in principle a volume increase of the extinguishing agent (Water and air) - through this a reduction in the diameter of a specific pressure nozzle or over a specific to the spray dish the sprinkler produced water droplets. In simple logic: "Smaller Drops of water in larger numbers "give an increase the extinguishing effect (a practice approved Effect).
Der erfindungsgemäße Injektor-Sprinkler ist eine den Sprinklerstandard verbessernde Problemlösung – prinzipiell eine kostengünstigere Option zwischen den konventionell verfügbaren Brandlöschtechnologien:
- – Sprühfluttechnik (Sprinkler)
- – Wassernebeltechnik (Hochdrucknebel).
- - Deluge technology (sprinkler)
- - Water mist technology (high pressure mist).
Der praktische Einsatz liegt zwischen dem den gesamten Sprinklereinsatzbereich umfassenden und spezifisch geeigneten Teilbereichen.Of the Practical use lies between the entire sprinkler application area comprehensive and specifically appropriate subareas.
In einem Ausführungsbeispiel sind ergänzende Details dargestellt und erläutert.In an embodiment are complementary Details presented and explained.
