Definitions

  • the invention relates to a fire extinguishing device for cargo holds of means of transport, in particular aircraft.
  • BULK baggage hold
  • air cargo which is usually housed in transport containers. This entire cargo hold is located under the passenger compartment of the commercial aircraft.
  • fire extinguishing devices consist of two separate fire extinguishing systems, each with its own line network.
  • first fire extinguishing system immediately after the first smoke alarm, suitable fire extinguishing agent containers filled with gaseous atmospheric pressure are extinguished in the affected cargo hold.
  • the rapid emptying of these fire extinguishing agent containers achieves a high fire extinguishing agent concentration in the cargo hold atmosphere, which quickly suffocates the fire that arises or arises.
  • a second fire extinguishing system then ensures that the fire extinguishing agent concentration in the cargo hold atmosphere does not fall below a defined limit for a certain fixed flight time.
  • In the pipe network of this second fire extinguishing system there are solid particle filters near the discharge nozzles for the fire extinguishing agent. Extinguishing agent gas dryers and devices to keep the extinguishing agent outflow rate constant.
  • the object of the invention is to provide a fire extinguishing device for cargo holds of commercial and / or cargo aircraft, which has a line network for both fire extinguishing operations, and in which there is no risk of icing and thus the failure of the second fire extinguishing phase.
  • the fire extinguishing device proposed here consists of a fire extinguishing device known per se with two fire extinguishing agent containers which preferably contain an extinguishing agent which is gaseous under atmospheric pressure.
  • the fire extinguishing agent containers have filling ports known per se and overpressure safety devices.
  • the extinguishing process is initiated by a smoke alarm device in the cargo hold, which triggers an optical and an acoustic signal on an instrument panel in the aircraft driver's cabin.
  • the fire extinguishing device is triggered by actuation of the trigger switches 16 in the aircraft driver's cabin, the safety membrane 8 being opened by an electrically triggered destruction device for emptying the first fire extinguishing agent container 1.
  • the extinguishing agent flows into the endangered cargo hold in a known manner and extinguishes the fire.
  • actuation of a further trigger switch 16 opens the safety membrane 8 in front of the emptying opening of the second fire extinguishing agent container 2, so that its fire extinguishing agent via a water absorption filter 5, a solid particle filter 7, a pressure reducer 6, an orifice 4 for limiting the outflow rate of the fire extinguishing device.
  • the one-way valve 3 prevents fire extinguishing agent from getting into the cleaning and metering devices 4, 5, 6 and 7 from the rear during the first extinguishing phase (FIG. 1).
  • both fire extinguishing agent containers can be emptied into the front cargo hold (FWD CC) or into the rear cargo hold (AFT CC) with the luggage hold (BULK), each of which contains two fire extinguishing agent outflow nozzles 12, via the common pipeline network (Fig . 2).
  • a filter arrangement is made available which can be used for cleaning an extinguishing agent stream of a fire extinguishing system.
  • this filter arrangement is defined as specified in the claims. Preferred embodiments of the filter arrangement are characterized in the subclaims.
  • the water absorption filter is therefore connected upstream of the particulate filter.
  • a relief line or by-pass line is connected in parallel to the water absorption filter.
  • a valve is arranged in this relief line, which opens when a certain pressure difference occurs at the water absorption filter. This largely prevents the adsorption material of the water absorption filter from being exposed to the initial shock wave of the extinguishing agent stream. Only after this initial shock wave has passed through the by-pass line does the valve in the by-pass line close and the extinguishing agent flows through the water adsorbent and is thereby dried.
  • FIG. 4 shows a preferred embodiment of a water adsorption filter (5) according to the invention.
  • An adsorbent container (53) preferably a cylindrical adsorbent container (53), is arranged in a filter housing (50) in the flow direction between an inlet line (51) and an outlet line (52).
  • this adsorbent container (53) there is particulate adsorbent material (54).
  • This material is preferably in molecular sieve material with an opening size or pore size in the range of about 3 * 10 ⁇ 10 to about 5 * 10 ⁇ 10 m.
  • a plate (56) is slidably arranged in the adsorbent housing (53) and is provided with openings for the passage of the extinguishing agent.
  • This plate (56) is pressed into the housing (53) by means of a prestressed spring (55) and thus keeps the adsorbent particles (54) in contact with one another and largely prevents any relative movement of the particles to one another.
  • the particles (54) are shaken together and the plate (56) thus prevents unacceptable rubbing off of the adsorption particles (54). If necessary, water-free extinguishing agent emerges from the outlet line (52). The water is adsorbed on the adsorption particles (54).
  • FIG. 5 schematically shows a particulate filter (7) which is arranged downstream of the water adsorption filter (5) in the system.
  • the solid particle filter (7) has a filter housing (70) in which, between an inlet line (71) and an outlet line (72), a filter unit consisting of a preferably hollow cylindrical filter element (73) and a lower end plate ( 75) and an upper end ring plate (76) is arranged.
  • the inside of the filter element (73) which preferably consists of filter material on a permeable carrier or reinforcing material, is connected to the end side (72) by the end ring plate (76).
  • This filter material is preferably fiber material, in particular organic or inorganic fiber material, which can filter particles up to 1.5 * 10 ⁇ 5 m in size or even smaller particles from the stream of extinguishing agent.
  • a fire extinguishing system shown in the drawing was operated with a typical fire extinguishing agent container which contained bromotrifluoromethane under 25 bar.
  • the system was operated without the water adsorption filter (5). This caused the nozzle opening to freeze within 50 minutes.
