Definitions

  • the invention relates to a method for extinguishing fires in rooms of buildings or the like with the aid of liquid particles.
  • sprinkler systems are used, via which the pressurized extinguishing water, which is located in a central storage container, is supplied to the rooms in buildings or on ships that catch fire. It has been shown that the water emerging from the sprinkler nozzles generally brings about the desired extinguishing success. Frequently, however, not insignificant damage to floors, walls or objects occurs in the rooms affected by the fire, which are not caused by the action of flame or heat but only by the extinguishing water.
  • the invention has for its object to further develop the fire extinguishing method of the type mentioned, while eliminating the disadvantages listed, so that fires occurring in rooms of buildings or the like can be extinguished with a minimum of damage by the extinguishing process.
  • the extinguishing liquid can be removed within a very short time, i.e. convert into a nebulous state in just a few seconds and convey it to the source of the fire in a relatively simple manner. Due to the extinguishing liquid mist descending on the latter, this stove is shielded very effectively, and it has been shown that the fire suffocates in a relatively short time. Extinguishing liquid dampening of the walls and ceilings as well as other objects is avoided.
  • the method according to the invention is characterized by the use of a blower for transferring the mist of extinguishing liquid to the source of the fire.
  • the method according to the invention can be used in a particularly advantageous manner, particularly in buildings or ships with rooms which are connected to air conditioning systems, since the extinguishing liquid mist can then be introduced via the branch of the air conditioning system leading to the room concerned.
  • the invention is also directed to a device for carrying out the method, which is characterized by a container with at least one sonotrode provided in the base area, which is used to atomize the extinguishing liquid present in the container, and a zone connected to the container and leading to the fire-endangered area ⁇ the channel through which the extinguishing liquid mist can be fed to a branch.
  • a container with at least one sonotrode provided in the base area which is used to atomize the extinguishing liquid present in the container, and a zone connected to the container and leading to the fire-endangered area ⁇ the channel through which the extinguishing liquid mist can be fed to a branch.
  • a '• correspondingly large-sized container can be supplied from which the emergency various areas or zones of a building or the like.
  • extinguishing liquid fog With extinguishing liquid fog.
  • a fan for the supply of an air flow carrying the mist is expediently connected to the container.
  • the channel which penetrates the container vertically opens at a distance from the container bottom and above the sonotrode.
  • the extinguishing liquid mist formed by the sonotrode then penetrates directly into the channel, with the entrainment of the air flow entering the container.
  • a particularly uniform air and therefore fog is achieved when the container is cylindrical is formed and if the mouth end of the channel passes through the container at a distance from the container wall, in particular if the cylindrical end of the channel concentrically passes through the container.
  • the container is assigned an extinguishing liquid tank which is connected to the container via a level valve which ensures a predetermined level of the extinguishing liquid in the container.
  • the device comprises a container 1, in the bottom area of which at least one sonotrode 2 is provided, which serves to atomize the extinguishing liquid 3 present in the container 1.
  • a channel 4 is connected to the container 1, which leads to the fire-endangered area in a manner which is not shown in detail, so that the extinguishing liquid mist can be fed via it to a source of fire in a room of a building, a ship or the like.

  • the level valve 8 ensures that a predetermined extinguishing liquid level of approximately 40 mm is maintained above the oscillating plate of the sonotrode 2, which is not shown in any more detail. If a fire breaks out, the sonotrode 2 is connected to the mains, i.e. supplied with energy, the extinguishing liquid 3 located above the sonotrode 2 is subjected to ultrasound such that its surface is torn open and the container space is filled with extinguishing liquid mist, in particular in the region of the channel 4. An extremely dense fog can be generated with ultrasound at a frequency of over 1 MHz. The extinguishing liquid mist is carried along by the air flow generated by the fan 5, which enters the channel 4 in the direction of the arrows through the container 1, and is conducted in the vicinity of the source of the fire.
  • the container can also be designed as part of a closed system which is preferably filled with inert gas and is under excess pressure.
  • the sonotrode ensures a fog-saturated state, so that when a fire breaks out, oversaturated steam can be supplied to the source of the fire by opening a switched-on valve or slide.
  • the sonotrode is designed so that its oscillating plate is able to withstand the pressure.

Abstract

Un procédé sert à éteindre des incendies dans des pièces intérieures de bâtiments ou similaires au moyen de particules de liquide. Afin d'éviter les dommages habituels du sol, des parois ou des objets se trouvant dans des pièces où un incendie s'est déclaré, provoqués non par le feu mais par l'eau d'extinction, le procédé comprend les étapes suivantes: vaporisation du liquide extincteur au moyen d'ultra-sons; application du brouillard de liquide extincteur vaporisé sur le foyer de l'incendie. Un agencement de mise en oeuvre de ce procédé comprend un conteneur (1) de liquide extincteur contenant au moins une sonotrode (2) agencée dans sa partie inférieure qui sert à vaporiser le liquide extincteur (3) contenu dans le conteneur. Un canal (4) menant jusqu'à la zone menacée par le feu est raccordé au conteneur (1) et sert à transporter le brouillard de liquide extincteur vaporisé jusqu'au foyer de l'incendie.
