Definitions

  • the invention relates to a fire extinguishing device consisting of a container with a solid extinguishing agent therein, which generates a finely dispersed, fire-extinguishing aerosol by means of controlled ignition by combustion within the container, which can be used emerging from the container in a space or project-related area.
  • Aerosol-forming fire extinguishing agents are known (EP 0560095 A1) and are subject to official regulations.
  • a fire extinguishing method is also known (EP 0578843 A1), in which the aerosol generator is set up as a mobile unit in areas to be protected.
  • the aerosol generator is also used as a mobile unit in an automatic extinguishing system (EP 0569025 A2).
  • the known devices have the disadvantage that the fire-extinguishing aerosol emerges freely from the aerosol generator and thus cannot be used specifically to fight a fire.
  • the aerosols emerge from it as suspended matter, which show a very poor sinking behavior and remain in the vicinity of the ceiling for a relatively long time.
  • the mixing of the room air with the aerosol is due to the sinking behavior of the suspended matter and is unsatisfactory because the extinguishing effect is poor.
  • the floor space that can be protected from a container is small.
  • the volume of space that can be protected is small.
  • the invention has for its object to provide a device in which the aerosols produced by combustion can be used in a stationary system, the mixing of the aerosol with the ambient air being improved.
  • the container is arranged outside of an area to be protected and is connected to a pipeline which is led into the area to be protected via a supply line and is provided at the end with a distributor nozzle.
  • the aerosol-generating container is arranged as a single container or in a group of several containers outside the area to be protected with the advantages known per se.
  • the pipelines are designed in such a way that the aerosol formed is subject to pressure build-up, so that the aerosol can be expelled via the pipelines and nozzles.
  • the pressure resulting from the combustion may not be sufficient to expel and mix the aerosol with the room air.
  • Additional pressure sources can then be used for expulsion, for example a booster pump or an inert gas.
  • This compressed gas can in turn be a known extinguishing agent, such as CO2, nitrogen, argon or INERGEN. It is then advisable not to lower the oxygen level below 17% and the CO2 concentration above 5% in order not to cause any danger to people.
  • the system can be optimized by using an injector or the like.
  • the heat generated during combustion can be used in which the additional extinguishing gas is evaporated, regardless of whether it is in liquid or solid form. The same applies to e.g. liquefied nitrogen. If the heat can accumulate in closed objects, this can be compensated for in a water bath or high-performance coolant.
  • the heat exchanger inside the tank can also be used as a cooler if necessary.
  • the distributor nozzles are designed in such a way that they let the aerosol emerge in the form of a jet and this jet sucks in room air and mixes it with the aerosol. This eliminates the floating effect of the known devices.
  • a fire extinguishing device 1 is used, for example, to protect an object 3 to be protected from a fire within an area 2 to be protected.
  • a container 4 or more containers 5, 6 are used, in which the fire-extinguishing aerosol is generated by combustion.
  • a known solid fire extinguishing agent 7 is used, which is burned within the container.
  • the combustion is initiated by an igniter 8, the igniter generating a temperature of approximately 1000 ° C.
  • the combustion produces the aerosol-containing extinguishing agent, which is fed via an outlet line 9, a feed line 12 and a distributor nozzle 14 into the area of the object 3 to be protected. If several containers 5 and 6 are provided, these are provided with outlet lines 10 and 11, the lines 9 to 11 being combined into a supply line 12.
  • the end of the supply line 12 is provided with a plurality of branch lines 13, at the ends of which the distributor nozzles 14 are then located.
  • This arrangement requires a long pipe run, so that a booster pump 15 is provided in the supply line 12.
  • a gas line 16 can be provided, by means of which a compressed gas can be introduced into the supply line 12.
  • a bypass line 17 with distributor lines 19 is provided, at the end of which there are outlet nozzles 20.
  • the distributor nozzles 14 and the outlet nozzles 19 can be designed in the same way. Valves 36 and 37 regulate the flow of the additional compressed gas.
  • the container 4 can be provided with a heat exchanger 20, to which an inlet line 21 for an additional extinguishing gas and an outlet line 22 for the heated extinguishing gas are assigned.
  • the extinguishing gas can be introduced directly into a Venturi tube 23 of the supply line 12. This also increases the pressure of the aerosol within the supply line Given 12.
  • the outlet lines 9 to 10 are provided with a transition piece 38 opposite the outlet opening of the container 4, as a result of which the pressure of the emerging aerosol is increased.
  • the distributor nozzle 14 and also the outlet nozzle 19 consist of a nozzle body 24 with nozzle openings 25. This is accommodated with its upper part 26 in a nozzle 27 to which a guide cup 28 is attached.
  • the branch line 13 is inserted into the connecting piece 27 and fastened there.
  • an aperture 29 is provided within the nozzle body 24.
  • directed jets of the aerosol or the extinguishing gas are generated, the jets forming extinguishing cones 34 and 35.
  • the quenching cones 34 form a common inner quenching cone which is surrounded by the quenching cones 35.
  • the outer extinguishing cones, which form a closed ring, have the effect that the aerosol is applied in a targeted manner to the object 3 to be protected.
  • the extinguishing device 1 is supplemented by a smoke detector 30 or the like, which is connected to a fire alarm control panel 31 via a line 39. From here, a control line 33 goes to control devices 32, which are connected to the ignition devices 8 of the containers 4.
  • the essence of the invention is to be seen in the fact that the container in which the aerosol produced by combustion is generated is arranged outside an area to be protected and is introduced via lines into the area to be protected.
