Description

Es ist ein Verfahren und eine Vorrichtung zum Ablöschen von Bränden in Behältern für brennbare Flüssigkeiten bekannt, nach welchem das aus halogenierten Kohlenwasserstoffverbindungen bestehende Löschmittel aus einem dicht oberhalb des brennenden Ölspiegels schwimmenden Düsensystem versprüht wird. Weiter ist bekannt, da,ß bei derartigen Bränden durch die turbulenten Strömungszonen der Brandsäule und die im :Gegenstrom zu diesen hereinbrechenden Frischluftschläuche eine gleichmäßig deckende Löschmittelaufbringung auf die brennende Oberfläche in- vielen Fällen schwierig ist. Insbesondere könnte das Hereinbrechen von Frischluft auch nicht :durch die Anbringung - eines Schirmes aus feuererstickender Masse verhindert werden.It is a method and apparatus for extinguishing fires known in containers for flammable liquids, after which the halogenated Extinguishing agent consisting of hydrocarbon compounds consisting of a just above the burning oil level floating nozzle system is sprayed. It is also known da, ß in such fires through the turbulent flow zones of the fire column and those in: countercurrent to these incoming fresh air hoses one evenly In many cases, it is difficult to apply the extinguishing agent to the burning surface is. In particular, the ingress of fresh air could not: through the Attachment - a screen made of fire-smothering mass can be prevented.

Vorliegende Erfindung hat nun ein Verfahren und eine Vorrichtung zum Gegenstand, mit deren Hilfe oberhalb .der eigentlichen Löschzone in dem Behälter für brennbare Flüssigkeiten Wasser durch Düsen versprüht wird. Wichtig ist, daß dieser Vorgang zur gleichen Zeit mit :dem Austritt des Löschmittels vor sich geht. Durch Ausbildung eines kegelförmigen Wassernebels ist es möglich, den Sauerstoffzustrom zur Brandfläche mit Sicherheit abzuriegeln. Die hiermit verbundene allgemeine Unterkühlung des Brandkomplexes schafft eine ruhigere Atmosphäre im Behälter. Mit Hilfe :der vorliegenden Erfindung werden die für eine erfolgreiche Bekämpfung des Brandes notwendigen Randbedingungen herbeigeführt. Somit wird der Löschvorgang wirksam unterstützt.The present invention now has a method and apparatus for Object, with the help of which above .the actual extinguishing zone in the container for flammable liquids, water is sprayed through nozzles. It's important, that this process takes place at the same time as: the discharge of the extinguishing agent. By forming a conical water mist, it is possible to control the flow of oxygen to be sealed off with security from the fire area. The associated general hypothermia of the fire complex creates a quieter atmosphere in the container. With the help of present invention are those necessary for a successful fire fighting Boundary conditions brought about. This effectively supports the deletion process.

In der Zeichnung ist ein Au.sführungsbei-spiel einer Löschvorrichtung gemäß der Erfindung dargestellt. Abb. i zeigt den Behälter mit der Löschvorrichtung im senkrechten Schnitt, und Abb. 2 ist die zugehörige Draufsicht.The drawing shows an exemplary embodiment of an extinguishing device shown according to the invention. Fig. I shows the container with the extinguishing device in vertical section, and Fig. 2 is the associated top view.

Der Behälter a enthält eine Löscnvorichtung b, die aus einem auf der brennenden Oberfläche schwimmenden Düsensystem e besteht, atis::dem das Löschmittel in Form von Strahlen d austritt. Auf dem Löschmittelverteilerkopf e sind die Wassernebeldüsen f angeordnet. Die Zuführung des Wassers erfolgt über den Schlauch g durch den Mittelzapfen h in die Sprühdüse f. The container a contains a release device b, which consists of a nozzle system e floating on the burning surface, from which the extinguishing agent emerges in the form of jets d. The water mist nozzles f are arranged on the extinguishing agent distributor head e. The water is supplied via the hose g through the central pin h into the spray nozzle f.
