Definitions

  • the invention relates to an extinguishing device designed for local firefighting in buildings at the location of a fire source according to the preamble of claim 1 and a corresponding method according to the preamble of claim 23. Furthermore, the present invention relates to an extinguishing system with a plurality of extinguishing devices of the aforementioned kind according to claim 19th
  • sprinkler systems are automatic fire extinguishing systems that are used for preventive fire protection in special buildings such as skyscrapers, commercial buildings, department stores, industrial plants, meeting places and underground garages.
  • special buildings such as skyscrapers, commercial buildings, department stores, industrial plants, meeting places and underground garages.
  • sprinkler heads On the ceiling or in the upper part of the side walls several water outlet nozzles, so-called sprinkler heads, attached, which are connected to a water pipe network.
  • the water outlet nozzles in turn are closed with glass ampoules, which are filled with a colored special liquid.
  • a constant water pressure which is controlled in the sprinkler control center.
  • the special liquid in the glass vials warms and expands, causing the ampoules to burst.
  • the nozzles are opened and the extinguishing water exits the sprinkler grid.
  • the resulting pressure drop is detected by a control device and leads to the opening of other valves and the start of pumps. From this point on, water is pumped into the sprinkler system from designated tanks or via a high-pressure water connection. This leaks at all open water nozzles and extinguishes or minimizes the fire.
  • a disadvantage of sprinkler systems is that they are often designed as systems interconnected over a large area, so that in the case of a small fire or in the case of a false triggering considerable damage from the sprayed Extinguishing agents are the result.
  • buildings can be retrofitted with the known, permanently installed sprinkler systems only with considerable effort.
  • extinguishing devices are known from the prior art, in which a fire extinguishing column is used for local fire fighting in buildings at the site of a fire.

For large rooms, it is also possible to install several room extinguishing columns.
  • the known room extinguishing columns allow the retrofitting of a building with low design cost and low cost, with false alarms can affect only a single room extinguishing column, resulting in less damage than in the false triggering of a sprinkler system. Due to the possibility of extinguishing a fire only locally in the surrounding area of the source of the fire, damage attributable to the sprayed extinguishing agent can be limited, which is particularly advantageous in the case of locally occurring comparatively small fire foci.
  • the known extinguishing columns have only a comparatively low effectiveness in local firefighting.
  • glowing can be erased only insufficiently with the known space extinguishing columns, which can lead to a rekindling of the fire after completion of the deletion process.

  • Firesorb® is a liquid polymer preparation that can absorb many times more water. This forms a heat-shielding gel that adheres even to ceilings and vertical walls. Due to its high toughness (viscosity), the Firesorb® gel only flows very slowly away from burning material and therefore remains extinguishing for longer. The protective film absorbs the heat of combustion at the surface, under which the air-closing function remains. Water added with Firesorb® acts as a liquid fire blanket, stifling the fire by closing the air and providing cooling. Firesorb® is a concentrate of superabsorbent polymer particles that are slightly pre-swollen with water.
