Abstract
Description
Die Erfindung betrifft ein Fettbrandlöschgerät als Flüssigkeitsdrucklöscher mit kleinem Füllvolumen.The invention relates to a grease fire extinguisher as a liquid pressure extinguisher with a small filling volume.
Das Löschen von Fettbränden stellt bisher ein großes Problem dar. Nach langen Tests unter anderem der Berufsgenossenschaften Nahrungsmittel und Gaststätten musste festgestellt werden, daß die bisher gebräuchlichen Löschmittel wie Pulver, Kohlendioxid usw. nicht oder nur ungenügend zum Löschen von Fettbränden geeignet sind. Aus diesem Grund wurden bereits spezielle Löschmittel für Fettbrände entwickelt. Ein solches für Fettbrände entwickeltes flüssiges Fettbrandlöschmittel ist unter der Produktbezeichnung "FettEx" bekannt und in Gebrauch. Um damit die nach europäischen Richtlinien festgesetzten Normen (EN3) zu erreichen, nämlich um die genormten Prüfobjekte erfolgreich ablöschen zu können, werden bisher mit diesem Fettbrandlöschmittel befüllte Flüssigkeitsdrucklöschgeräte, wie sie bisher auch als Wasser- oder Schaumlöscher eingesetzt werden, mit einem Füllvolumen von mindestens 6 Liter verwendet, um eine zum Ablöschen von Fettbränden ausreichende Menge des flüssigen Fettbrandlöschmittels aufbringen zu können.The eradication of fat burns has been a major problem. After long tests, including the professional associations food and catering establishments had to be found that the previously used extinguishing agents such as powder, carbon dioxide, etc. are not or insufficiently suitable for extinguishing fat burns. For this reason, special extinguishing agents have been developed for fat burns. Such a liquid fat fire extinguishing agent developed for fat burning is known under the product name "FettEx" and in use. In order to achieve the standards set by European directives (EN3), namely to be able to successfully extinguish the standardized test objects, liquid pressure extinguishers, which were previously used as water or foam extinguishers and filled with this grease fire extinguishing agent, have a filling volume of at least 6 Liter used to apply sufficient to extinguish fat burns amount of liquid fat fire extinguisher can.
Ein Fettbrandlöschgerät gemäss dem Oberbegriff von Anspruch 1 ist aus dem Dokument DE 203 01 378 bekannt.A grease fire extinguisher according to the preamble of claim 1 is known from the document DE 203 01 378.
Der Erfindung liegt die Aufgabe zugrunde, ein Fettbrandlöschgerät zu schaffen, das bei gleichem Löscherfolg mit bedeutend weniger Fettbrandlöschmittel auskommt.The invention has for its object to provide a grease fire extinguisher, which manages with the same fire extinguishing with significantly less fat fire extinguishing agent.
Diese Aufgabe wird gemäß der Erfindung durch das im Anspruch 1 angegebene Fettbrandlöschgerät gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved according to the invention by the fat fire extinguisher specified in claim 1. Advantageous embodiments of the invention are the subject of the dependent claims.
Das erfindungsgemäße Fettbrandlöschgerät arbeitet also mit einer besonders konfigurierten Düse im Gegensatz zu den bisher zum Löschen von Fettbränden benutzten, zwar mit flüssigem Fettbrandlöschmittel befüllten, aber ansonsten einschließlich Löschschlauch und Löschpistole herkömmlich aufgebauten Flüssigkeitsdrucklöschern. Die damit unerwartet erreichte Wirkung ist dermaßen erheblich, daß statt der bisher in Flüssigkeitslöschern zum sicheren Löschen von Fettbränden erforderlichen Minimalmenge an flüssigem Fettbrandlöschmittel "FettEx" von sechs Litern nunmehr ein sicherer Löscherfolg mit nur zwei Liter Füllvolumen erreicht werden kann.The fat fire extinguisher according to the invention thus operates with a specially configured nozzle in contrast to the previously used to extinguish fat burns, although filled with liquid grease extinguishing agent, but otherwise including extinguishing hose and extinguisher conventionally constructed liquid pressure extinguishers. The thus unexpectedly achieved effect is so considerable that instead of the previously required in liquid extinguishers for safe extinguishment of grease fires minimum amount of liquid grease fire extinguisher "FettEx" of six liters now a safe extinguishing success can be achieved with only two liters of filling volume.
Das Löschmittel "FettEx" (Zulassungsnummer PL 13 / 2000") ist ein spezielles flüssiges Löschmittel für Öle und Speisefette, das eine geschlossene gasdichte Schaumdecke ergibt und das Feuer sofort erstickt. Es hat auch einen sehr guten Kühleffekt, wodurch dem Öl oder Fett sowie der umgebenden Einrichtung sofort Wärme entzogen wird. Von großer Bedeutung ist aber, daß das Löschmittel dazu fein verteilt ausgebracht werden muß.The extinguishing agent "FettEx" (approval number PL 13/2000 ") is a special liquid extinguishing agent for oils and fats that creates a closed gas-tight foam blanket and immediately stifles the fire However, of great importance is that the extinguishing agent must be applied to finely distributed.
Die gebrauchsfertige kommerziell verfügbare Fettbrandlöschmittellösung "FettEx" hat folgende technische Spezifikation:
Dabei muß beachtet werden, daß zum Erreichen eines optimalen Löschergebnisses ein Löschimpuls nachfolgender Formel eingehalten werden muß:
Das erfindungsgemäße Fettbrandlöschgerät bringt gerade, weil es mit einer geringen Löschmittelmenge auskommt, entscheidende Vorteile. Geht man einmal von einer Situation einer großen Friteuse mit einer Füllmenge von 36 kg Frittierfett aus, wie dies der Situation in der Praxis bei Gastronomiebetrieben entspricht und wie dies auch als genormtes Prüfobjekt für Löschleistungsversuche vorgesehen ist, wird beim Ablöschen einer solchen brennenden Friteuse mit einem herkömmlichen Löscher mit mindestens 6 Liter Füllvolumen bereits die Gefahr des Überlaufens der Friteuse mit dem Auslaufen von brennendem heißem Fett begründet, wovon eine große Gefahr ausgeht, weil durch übergelaufenes Fett selbst dann, wenn es schon abgelöscht wurde, andere Gegenstände in Brand gesetzt werden können, weil das überlaufende Fett immer noch eine Temperatur von ca 300°C hat. Gefährlich ist es auch, wenn ausgelaufenes Fett mit Wasser in Berührung kommt, was zum schlagartigen Verdampfen des Wassers mit Gefahr für anwesende Personen durch Verbrühen nach sich zieht.The fat fire extinguisher according to the invention brings decisive advantages because it requires only a small quantity of extinguishing agent. Assuming once a situation of a large fryer with a capacity of 36 kg frying fat, as is the situation in the practice of catering establishments and as this is also intended as a standard test object for Löschleistungsversuche is when extinguishing such a burning fryer with a conventional Extinguisher with at least 6 liters of filling volume already justified the risk of overflowing the fryer with the leakage of burning hot fat, which poses a great danger, because through overflowed grease, even if it has already been extinguished, other objects can be set on fire, because the overflowing grease still has a temperature of about 300 ° C. It is also dangerous when leaking grease comes into contact with water, which leads to the sudden evaporation of the water with danger to persons present by scalding.
Die Wirkung des erfindungsgemäßen Fettbrandlöschgeräts besteht darin, daß das Ausbringen des flüssigen Fettbrandlöschmittels in einer optimierten Form stattfindet und dieses Fettbrandlöschmittel so in geringer Menge die optimale Löschwirkung entfaltet.The effect of the fat fire extinguisher according to the invention is that the application of the liquid fat fire extinguishing agent takes place in an optimized form and this fat fire extinguishing agent so unfolds the optimal extinguishing effect in a small amount.

Das erfindungsgemäße Fettbrandlöschgerät ist als Flüssigkeitsdrucklöschgerät mit einem Löschmittelbehälter von zwei Liter Füllmenge und einer besonders konfigurierten Düse ausgebildet. Das Gerät arbeitet mit einem Betriebsdruck von 12 bis 18 bar.The fat fire extinguisher according to the invention is designed as a liquid pressure extinguisher with an extinguishing agent container of two liters capacity and a specially configured nozzle. The device operates at an operating pressure of 12 to 18 bar.
In den Zeichnungen dargestellt ist nur die Düse, da das Löschgerät im übrigen von herkömmlicher Bauart ist. Die Düse, die in den Fig. 1 bis 3 der Zeichnungen dargestellt ist, ist direkt in das Auslassventil des Löschmittelbehälters eingeschraubt.In the drawings, only the nozzle is shown, since the extinguisher is otherwise of conventional design. The nozzle shown in Figs. 1 to 3 of the drawings is screwed directly into the outlet valve of the extinguishing agent container.
Gemäß den Zeichnungen ist die Düse als Becherkörper 1 mit einem mit Außengewinde versehenen Einschraubhals 2 zum Einschrauben in das Auslassventil ausgebildet. In dem Becherkörper ist eine Zerstäubungsplatte 3 eingesetzt, die eine kranzartige Anordnung von beim Ausführungsbeispiel sechs Düsenöffnungen 4 enthält. Der Raum hinter der Zerstäubungsplatte 3 im Becherkörper ist als divergierende Diffusorkammer ausgebildet. Die Düsenöffnungen 4 sind jeweils relativ klein und erweitern sich nach hinten in der Zerstäubungsplatte 3 über einen Konus mit großem Kegelwinkel in eine zylindrische, nach hinten offene Bohrung wesentlich größeren Durchmessers, in die jeweils ein Drallkörper 5 eingesetzt ist. Die Drallkörper 5 sind in der Auseinandergezogenen Darstellung nach Fig. 1 gut erkennbar, und ihre Anordnung in der Zerstäubungsplatte 3 ist in dem Schnitt nach Fig. 3 deutlich sichtbar. Die Drallkörper 5 bewirken in Zusammenwirken mit den Düsenöffnungen 4 die Zerstäubung des aus dem Löschmittelbehälter durch den Einschraubhals 2 zugeführten flüssigen Löschmittels in einen gleichmäßigen divergierenden Sprühstrahl von etwa 40 cm Durchmesser. Bei dem oben erwähnten Betriebsdruck des Geräts von 12 bis 18 bar wird eine Wurfweite von ca. 2 bis 3 Meter erreicht.According to the drawings, the nozzle is designed as a cup body 1 with an externally threaded
Das Flüssigkeitslöschgerät ist zweckmäßigerweise als Dauerdrucklöscher ausgeführt. Da bei Dauerdrucklöschern während des fortschreitenden Löschvorgangs der Druck allmählich abfällt, reduziert sich dementsprechend die Wurfweite. Für den hier gegebenen Anwendungsfall zum Löschen von Fettbränden kommt diesem Umstand allerdings keine Bedeutung zu.The liquid extinguisher is expediently designed as a permanent pressure extinguisher. Since with continuous pressure extinguishers during the progressive deletion of the pressure gradually decreases, accordingly reduces the throw distance. For the application given here to extinguish fat burns, however, this circumstance is of no importance.
Aufgrund der besonderen Konfiguration der Düse des erfindungsgemäßen Fettbrandlöschgeräts, wie sie in den Fig. 1 bis 3 dargestellt ist, wird ein sehr fein zerstäubter gleichmäßiger Sprühstrahl mit einem Durchmesser von etwa 40 cm erzeugt, der schnell eine dichte Löschmittelschicht über dem Brandherd bildet und mit wenig Löschmitteleinsatz ein Ersticken des Brands und eine schnelle Abkühlung des Brandherds bewirkt.Due to the particular configuration of the nozzle of the fat-burning extinguisher according to the invention, as shown in Figs. 1 to 3, a very finely atomized becomes more uniform Spray jet with a diameter of about 40 cm generated that quickly forms a dense extinguishing agent layer over the fire and causes with little use of extinguishing a suffocation of the fire and rapid cooling of the fire.
