Definitions

  • the invention relates to a filter device for fire extinguishing devices for cargo holds of means of transport, in particular aircraft.
  • fire extinguishing devices consist of two separate fire extinguishing systems, each with its own line network.
  • first fire extinguishing system fire extinguishant containers filled with suitable fire-extinguishing agent that are gaseous under atmospheric pressure are completely emptied into the affected cargo hold immediately after the first smoke alarm. Due to the rapid emptying of these fire extinguishing agent containers, a high fire extinguishing agent concentration is achieved 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 specified limit for a certain remaining flight time.
  • this second fire extinguishing system there are solid particle filters, extinguishing agent gas dryers and facilities for keeping the fire extinguishing agent outflow rate constant near the outlet nozzles for the fire extinguishing agent.
  • the object of the invention is to provide a filter device of 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 failure of the second fire extinguishing phase.
  • the fire extinguishing device 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 actuating the trigger switches in the aircraft driver's cabin, the safety membrane 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.
  • a further trigger switch opens the safety membrane in front of the emptying opening of the second fire extinguishing agent container 2 after 60 minutes, so that its fire extinguishing agent via a water adsorption filter 5, a solid particle filter 7, a pressure reducer 6, an orifice 4 for limiting the outflow rate and a
  • a one-way valve 3 enters the common pipe network 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 or into the rear cargo hold, with the luggage hold, in which two fire extinguishing agent outflow nozzles 12 are located, via the common pipeline network.
  • a filter device or a filter arrangement 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 solid particle filter.
  • a bypass line 57 (FIG. 2) is connected in parallel to the water absorption filter.
  • a valve is arranged in this relief line and opens when a certain pressure difference occurs at the water absorption filter. In this way it is largely prevented that the adsorption material of the water absorption filter is exposed to the initial shock wave of the extinguishing agent flow. 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. 2 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 a 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 movement of the particles relative 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).
  • a particulate filter (7) is shown schematically, 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 extinguishing agent stream.
  • 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.
