Abstract

Appts. is used to produce a fire wall surrounding the burning oil source. The combustible material for the wall can be gas-form or liq., and is applied with pressure. Varying local conditions of burning oil sources can require several ring-shaped devices of varying dias. at various heights. Also used is a device for the targeted introduction of a fluid inert gas into the centre of the fire, e.g. in the form of a rollable and extendable pipe conduit. The fire wall causes a withdrawal of air oxygen required for the oil to burn, thereby extinguishing the flame. The liq. inert gas adheres to surfaces in the region of the extinguished flame, thereby having a cooling effect and preventing a recurrence of the fire. ADVANTAGE - For extinguishing burning oil wells.

Description

1. Das vorgenannte Verfahren gehört zum technischen Gebiet der Brandbekämpfung.1. The aforementioned method belongs to the technical field of Firefighting.

2. Nach dem Kenntnisstand der Patenteinreicher werden gegenwärtig brennende Ölquellen mit Sprengungen zum Verlöschen gebracht. Dieses Verfahren ist technisch schwierig, allein die Zeiträume der Brandbekämpfung nach diesem Verfahren belegen das.2. According to the knowledge of the patent applicants are currently burning oil wells with explosions extinguished. This process is technically difficult, only the periods firefighting according to this procedure prove this.

3. Das o.g. Verfahren beruht auf dem Prinzip, durch eine die brennende Ölquelle umschließende Feuerwand der brennenden Öl­ quelle den für ihren Brand erforderlichen Luftsauerstoff zu entziehen. Beim Brennen der Ölquelle entsteht durch die lo­ dernde Flamme ein nach oben gerichteter Sog, der Luftsauer­ stoff wird von unten und seitlich angesaugt. Die die Ölquelle umschließende ringförmige Feuerwand holt den für ihren Brand erforderlichen Luftsauerstoff innen aus dem Ring - das ist der, der für den Brand der Ölquelle erforderlich ist - und aus dem äußeren Bereich des Ringes (für die Wirkung nicht rele­ vant). Fehlt nun der Luftsauerstoff im Inneren des Ringes, kann die brennende Ölquelle nicht mehr bestehen. Sie muß zum Erlöschen kommen. Ein flüssiges Inertgas in das Zentrum der Ölquelle geleitet, soll noch glühende Teile des Ölfördermechanismusses kühlen und löschen, um eine Wiederentzündung des ausströmenden Öls zu verhindern.3. The above The process is based on the principle through which the burning oil well surrounding fire wall of burning oil swell the atmospheric oxygen required for your fire revoke. When burning the oil well, the lo the flame is an upward pull, the air sour fabric is sucked in from below and from the side. The the oil well enclosing ring-shaped fire wall brings the for her fire required atmospheric oxygen inside from the ring - that is the one that is necessary for the fire of the oil well - and off the outer area of the ring (for the effect not rele vant). If there is no air oxygen inside the ring, the burning oil well can no longer exist. You must go to Coming out. A liquid inert gas is directed to the center of the oil well, is said to cool and still glowing parts of the oil production mechanism extinguish to reignite the escaping oil prevent.

4. Die Erfindung, für die in den Patentansprüchen Schutz begehrt wird, ist das unter Tz. 3 beschriebene Verfahren.4. The invention for which protection is sought in the claims is the procedure described under item 3.

5. Gewerblich anwendbar ist die Erfindung z. B. bei den jetzt brennenden Ölquellen in Kuweit. Ein weltweiter Aufruf zum Fin­ den unkonventioneller Methoden zur Eingrenzung der ökologi­ schen Katastrophe veranlaßte die Erfinder zum Einreichen des Patents. Ihnen ist bewußt, daß es bis zur Erteilung des Patents für sie kaum einen Schutz ihrer Rechte gibt. Trotzdem ist das Problem so groß, daß die Erfinder bereits jetzt in ge­ eigneter Form bei Behörden vorstellig und in die Öffentlich­ keit gehen werden.5. The invention is commercially applicable, for. B. at the now burning oil wells in Kuwait. A worldwide call for fin the unconventional methods to limit the ecological catastrophe prompted the inventors to submit the Patents. You are aware that until the grant of the Patents for them hardly protect their rights. Nevertheless the problem is so great that the inventors are already in ge suitable form presented to the authorities and publicly will go.

6. Die vorteilige Wirkung der Erfindung - die mit nicht unerheb­ lichen Aufwendungen erst erprobt werden muß - besteht darin, daß die bis jetzt üblichen Methoden zur Lösung des Problems zeitlich verkürzt werden könnten.6. The advantageous effect of the invention - which with not insignificant expenses must first be tested - consists of that the previously common methods of solving the problem could be shortened in time.

Verfahren zum Löschen einer brennenden Ölquelle, das besteht aus:
  • - einer Vorrichtung zur Erzeugung einer die brennende Ölquelle umschließenden Feuerwand. Das Brennmaterial für die Erzeugung der Feuerwand kann gas­ förmig oder flüssig sein und mit Druck in die Vorrichtung geleitet werden. (Unterschiedliche örtliche Bedingungen von brennenden Ölquellen können mehrere ringförmige Vorrichtungen in verschiedenen Durchmessern in verschiedenen Höhen erfordern).
  • - einer Vorrichtung zum gezielten Heranbringen eines flüssigen Inertgases in das Zentrum der brennenden Ölquelle, z. B. in Form einer roll- und verlängerbaren Rohrleitung,
Procedure for extinguishing a burning oil well, which consists of:
  • - A device for producing a fire wall surrounding the burning oil well. The fuel for the production of the fire wall can be gaseous or liquid and can be passed under pressure into the device. (Different local conditions from burning oil wells may require multiple annular devices of different diameters at different heights).
  • - A device for selectively bringing a liquid inert gas into the center of the burning oil well, for. B. in the form of a rollable and extendable pipeline,
dadurch gekennzeichnet, daß man
  • a) durch eine Feuerwand den für das Brennen der Ölquelle erfor­ derlichen Luftsauerstoff der brennenden Ölquelle entzieht und dadurch die Flamme der brennenden Ölquelle erstickt,
  • b) durch ein flüssiges Inertgas glühende Teile im Bereich der erstickten Flamme der Ölquelle kühlt und löscht, um so ein Wiederentfachen der Ölquelle durch verbleibende Zündquellen zu verhindern,
  • c) nach Ersticken der Flamme nach a) und der Beseitigung noch vor­ handener Zündquellen nach b) die Feuerwand durch Absperren der Zufuhr des für ihren Betrieb erforderlichen Brennstoffes zum Erlöschen bringt.
 characterized in that one
  • a) withdraws the atmospheric oxygen required for the burning of the oil source from the burning oil source by a wall of fire and thereby suffocates the flame of the burning oil source,
  • b) cools and extinguishes parts glowing in the area of the suffocated flame of the oil source by means of a liquid inert gas, in order to prevent the oil source from reigniting due to remaining ignition sources,
  • c) after suffocation of the flame according to a) and the elimination of existing ignition sources according to b) the fire wall by shutting off the supply of the fuel necessary for its operation to extinguish.
