Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Löschen eines Tanklagers, bei dem mit Silan gefüllte Tanks in einer Auffangwanne stehen. Die Tanks, mit einer Höhe von ca. 10 Metern stehen senkrecht. Silan wird zur Produktion von reinem Silizium und Silikonen verwendet und ist äußerst explosiv und feuergefährlich. Bei Leckagen im Pumpenbereich oder bei Flanschundichtigkeiten führt es zur Freisetzung von HCL-Dämpfen. Silan hat einen Flammpunkt von -20 °C.The invention relates to a method and a device for extinguishing a tank farm, in which tanks filled with silane stand in a collecting trough. The tanks, with a height of about 10 meters, are vertical. Silane is used for the production of pure silicon and silicones and is extremely explosive and flammable. If there are leaks in the pump area or flange leaks, this leads to the release of HCL vapors. Silane has a flash point of -20 ° C.

Brandversuche mit Silan-Flüssigkeiten haben eine äußerst schnelle Flammentwicklung mit enormer Hitze und Thermik ergeben. Bei einem Brandversuch konnte eine Hitzeentwicklung von 1300 °C innerhalb von 30 Sekunden bei einer Höhe von 2 Metern über der Wanne festgestellt werden. Das Feuer wurde mit CO₂-Niederdruck mittels Straßentankwagen gelöscht.Fire tests with silane liquids have shown extremely rapid flame development with enormous heat and thermals. In a fire test, a heat development of 1300 ° C was found within 30 seconds at a height of 2 meters above the tub. The fire was extinguished with CO₂ low pressure using road tankers.

Der Erfindung liegt die Aufgabe zugrunde aufgrund von Leckagen oder dergleichen ausgelaufenes und in der Auffangwanne gesammeltes Silan schnell und sicher zu löschen.The invention has for its object to quickly and safely quench leaked or the like leaked and collected in the drip pan silane.

Diese Aufgabe wird dadurch gelöst, daß die in der Auffangwanne brennende Silan-Flüssigkeit mit CO₂ abgedeckt wird, das einer CO₂-Anlage mit automatisch auslösendem Anregersystem entnommen ist und daß oberhalb der CO₂-Schicht eine von einem Lochblech getragene Löschschaumschicht aufgegeben wird.This object is achieved in that the burning silane liquid is covered with CO₂, which is taken from a CO₂ system with an automatically triggering excitation system and that above a layer of extinguished foam carried by a perforated sheet is given up in the collecting pan with CO₂.

Die Kombination von CO₂ und Löschschaum ergibt ein schnelles und sicheres Ablöschen des brennenden Silans, weil die Schaumschicht das Löschmittel CO₂ nach unten hält und damit verhindert, daß die Flammen nach oben durchschlagen. CO₂ und Löschschaum können gleichzeitig aber auch nacheinander eingebracht werden. In jedem Falle kann die jeweilige Auffangwanne ohne Verzögerung mitCO₂ geflutet werden, weil Personengefahr nicht besteht. Im Normalfall werden die Auffangwannen von Personen nicht frequentiert. Im Falle einer Reparatur wird die Anlage von der Werksfeuerwehr außer Betrieb genommen. Die Schaumschicht kann von der Werksfeuerwehr mittels Schaumfahrzeugen aufgetragen werden.The combination of CO₂ and extinguishing foam results in a quick and safe extinguishing of the burning silane because the foam layer holds the extinguishing agent CO₂ down and thus prevents the flames from penetrating upwards. CO₂ and extinguishing foam can also be introduced one after the other. In any case, the respective Collection pan can be flooded with CO₂ without delay because there is no danger to people. Normally, the collecting trays are not used by people. In the event of a repair, the plant is shut down by the plant fire brigade. The foam layer can be applied by the factory fire department using foam vehicles.

Eine vorteilhafte Vorrichtung zur Durchführung des Verfahrens wird darin gesehen, daß die Auffangwanne mit Abstand vom Wannenboden und mit Abstand zum oberen Wannenrand mit einem Lochblech versehen ist, daß unterhalb des Lochbleches eine an eine CO₂-Leitung angeschlossene Ringleitung vorgesehen ist, an die mehrere gleichmäßig verteilte Löschschienen mit zum Wannenboden gerichteten Austrittsöffnungen oder Düsen angeschlossen sind, und daß oberhalb des Lochbleches im Bereich des oberen Wannenrandes eine an eine Löschschaumleitung angeschlossene Ringleitung vorgesehen ist, an die mehrere gleichmäßig verteilte, zum Lochblech hin geöffnete Schaumrohre vorgesehen sind.An advantageous device for performing the method is seen in the fact that the collecting trough is provided with a perforated plate at a distance from the trough bottom and at a distance from the upper trough edge, that a ring line connected to a CO₂ line is provided below the perforated plate, to which several are evenly distributed Extinguishing rails are connected with outlet openings or nozzles facing the trough bottom, and that above the perforated plate in the area of the upper trough edge there is provided a ring line connected to an extinguishing foam line, to which several evenly distributed foam tubes open towards the perforated plate are provided.

Mit dieser Einrichtung ist ein gleichmäßiges Fluten des unteren Teiles der Auffangwanne mit CO₂ sichergestellt, wobei eine auf das Lochblech aufgebrachte Löschschaumschicht das CO₂ im unteren Raum festhält.With this device, a uniform flooding of the lower part of the drip pan with CO₂ is ensured, with an extinguishing foam layer applied to the perforated plate holding the CO₂ in the lower space.

Die CO₂-Leitung kann an eine außerhalb der Auffangwanne aufgestellte stätionäre CO₂-Anlage angeschlossen sec Ebenso kann die Löschschaumleitung an eine außerhalb der Auffangwanne aufgestellte Löschschaumleitung angeschlossen sein. Anstelle einer stationären Löschschaumanlage kann auch eine mobile Anlage, beispielsweise ein Feuerwehr-Löschschaum-Fahrzeug eingesetzt werden.The CO₂ line can be connected to a stationary CO₂ system set up outside the drip pan. Likewise, the extinguishing foam line can be connected to a fire foam line set up outside the drip pan. Instead of a stationary fire-fighting foam system, a mobile system, for example a fire-fighting fire-fighting foam vehicle, can also be used.

In jedem Falle muß sichergestellt sein, daß die Lochung des Lochbleches derart ausgebildet ist, daß der Durchtritt eines Löschschaumes mit einer Verschäumungszahl zwischen 100 und 400 nach unten verhindert wird. Zu diesem Zweck werden die Durchmesser der Lochungen des Lochbleches zwischen 5 und 10 mm Durchmesser ausgebildet. Um das Lochblech vor Schäden zu bewahren, kann es von einem begehbaren Gitterrost getragen sein.In any case, it must be ensured that the perforation of the perforated plate is designed such that the passage of extinguishing foam with a foaming number between 100 and 400 down is prevented. For this purpose, the diameters of the perforations of the perforated plate are between 5 and 10 mm in diameter. In order to protect the perforated plate from damage, it can be carried by a walk-on grating.

Das Tanklager 1 besteht aus einer Auffangwanne 2, in der mehrere senkrecht aufstehende Tanks 3 aufgestellt sind. Mit einem Abstand 5 vom Boden 6 und mit einem Abstand 7 vom oberen Wannenrand 8, ist ein Lochblech 4 vorgesehen. Unterhalb dieses Lochbleches 4 ist eine Ringleitung 10 angebracht, die einerseits an eine CO₂-Leitung 9 angeschlossen ist und an die andererseits mehrere gleichmäßig verteilte Löschschienen 11 über Stichleitungen 12 angebracht sind. Die Löschschienen 11 sind mit Bohrungen oder Düsen 13 versehen, durch die das Löschmittel CO₂ nach unten auf den Boden 6 der Auffangwanne 2 gerichtet wird. Oberhalb des Bodenbleches 4 im Bereich des oberen Wannenrandes 8 sind mehrere Ringleitungen 15 angeschlossen. Diese sind wiederum mit einer Löschschaumleitung 14 verbunden.The tank farm 1 consists of a collecting trough 2 in which several tanks 3 standing upright are set up. A perforated plate 4 is provided at a distance 5 from the floor 6 and at a distance 7 from the upper tub edge 8. Below this perforated plate 4, a ring line 10 is attached, which is connected on the one hand to a CO₂ line 9 and on the other hand, several evenly distributed extinguishing rails 11 are attached via stub lines 12. The extinguishing rails 11 are provided with holes or nozzles 13 through which the extinguishing agent CO₂ is directed down to the bottom 6 of the sump 2. A plurality of ring lines 15 are connected above the base plate 4 in the region of the upper tub edge 8. These are in turn connected to an extinguishing foam line 14.

Die CO₂ Leitung 9 ist mit einer CO₂-Anlage 8 verbunden. Diese besteht aus einem CO₂-Behälter 19 oder aus CO₂-Gasflaschen. Sie ist mit einem Schnellöffnungsventil 20 und einer Auslöseeinrichtung 21 versehen. Von dieser geht eine Regelleitung 33 zu einer Brandmeldezentrale 22, der über eine Leitung 23 automatisch eine Brandmeldeeingabe zugeführt wird. Das Schnellöffungsventil 20 kann auch über eine Handauslösung 24 betätigt werden. Im Brandfalle geht von der Brandmeldezentrale 22 ein Signal zum Signalgeber 25.The CO₂ line 9 is connected to a CO₂ system 8. This consists of a CO₂ container 19 or CO₂ gas bottles. It is provided with a quick opening valve 20 and a triggering device 21. From this a control line 33 goes to a fire alarm center 22, to which a fire alarm input is automatically fed via a line 23. The quick opening valve 20 can also be operated via a manual trigger 24. In the event of a fire, a signal goes from the fire control center 22 to the signal generator 25.

Die Löschschaumanlage 26 besteht aus dem Schaummittelbehälter 27, der Schaummittelpumpe 28 und dem Zumischregler 29, der mit einer Löschwasserzuführung 30 verbunden ist. Ein Absperrventil 31 mit einer Fernbetätigung 32 und der Regelleitung 33 zu der nicht dargestellten Brandmeldezentrale 22 ist mit der Löschschaumleitung 14 verbunden.The extinguishing foam system 26 consists of the foam agent container 27, the foam agent pump 28 and the admixing regulator 29, which is connected to an extinguishing water supply 30. A shut-off valve 31 with a remote control 32 and the control line 33 to the fire alarm control panel 22, not shown, is connected to the extinguishing foam line 14.

Im Falle einer Leckage im Pump- oder Leitungssystem sammelt sich Silan-Flüssigkeit 36 am Boden 6 der Auffangwanne 2. Entzündet sich diese Flüssigkeit wird über das nicht dargestellte Anregersystem und die Anregerleitung 23 das Schnellöffnungsventil 20 des CO₂-Behälters 19 geöffnet und damit der Raum 34 unterhalb des Bodenbleches 4 mit CO₂ geflutet. Damit dieser Raum mit CO₂ geflutet bleibt, wird gleichzeitig oder nacheinander mittels der Schaumrohre 16 und der Löschschaumanlage 26 eine Schaumschicht 35 auf dem Lochblech 4 aufgelegt. Diese Schaumschicht verhindert ein Aufsteigen des CO₂-Löschmittels nach oben, so daß dieses intensiv und schnell den Brand der Silan-Flüssigkeit 36 löschen kann Mit 37 ist eine Gitterrost bezeichnet an den das Lochblech 4 aufgehängt ist. Der Gitterrost 37 ist so stabil ausgebildet daß er begehbar ist.In the event of a leak in the pump or line system, silane liquid 36 collects at the bottom 6 of the collecting trough 2. If this liquid ignites, the quick-opening valve 20 of the CO₂ container 19 is opened via the excitation system (not shown) and the excitation line 23, and thus the space 34 flooded with CO₂ below the bottom plate 4. So that this space remains flooded with CO₂, a foam layer 35 is placed on the perforated plate 4 at the same time or in succession by means of the foam tubes 16 and the extinguishing foam system 26. This foam layer prevents the CO₂ extinguishing agent from rising upwards, so that it can extinguish the fire of the silane liquid 36 intensively and quickly. 37 is a grating on which the perforated plate 4 is suspended. The grating 37 is so stable that it can be walked on.
