Definitions

  • the invention relates to a powder extinguishing system for installation on a powder fire-fighting vehicle or for installation in a combined fire-fighting vehicle, consisting of a container filled with an extinguishing powder, which is pressurized via a charging line by means of a high-pressure propellant gas filled in separate high-pressure containers, in which the High-pressure propellant gas is supplied to the powder container by means of a pressure reduction in the charging line and the powder container is charged up to an operating pressure, one or more consumers being connected to the container via extraction pipes.
  • Such systems work according to the dry extinguishing method, with fine-grained dry extinguishing powder which is sprayed out under pressure from nitrogen or the like via hoses with connected extinguishing pistols or via a powder launcher.
  • This creates a dense cloud of extinguishing cloud, which becomes larger as the distance from the extinguishing gun or the powder launcher increases, with which a source of fire can be enveloped and the fire suddenly suffocated. Since the extinguishing pistol and the powder launcher can be switched on or off at will, there is the possibility of using the extinguishing agent in shots (sparingly), particularly in the subsequent fight against hidden sources of fire or in the event of post-ignition.
  • the extinguishing powder must be mixed with a compressed gas in the powder container.
  • nitrogen bottles are used, for example, which have a filling pressure of 200 bar.
  • the compressed gas is also introduced into the powder container via a reducing valve by means of a feed line.
  • the known systems work according to the normal pressure or the high pressure process.
  • the powder-filled boiler is pressurized with nitrogen under a pressure of approx. 14 bar.
  • the powder-filled boilers are permanently under a pressure of 30 bar.
  • Both methods have the disadvantage that the boiler wall must be relatively thick due to the operating pressures, which is reflected in the boiler weight and in the purchase price.
  • the object of the invention is to create a powder extinguishing system, in particular for fire-fighting vehicles, which is lighter and less expensive and thus a more optimal one Utilization of the vehicle enables.
  • This object is achieved in that the operating pressure is equal to or less than 4 bar and in that a discharge tube is connected on the outlet side to one of the sampling tubes and a gas supply line is introduced on the inlet side into the sampling tube, which is at its lower end between the check valve and the low pressure regulator with the charging line connected is.
  • the extinguishing powder can be discharged from the extraction tube with the directly assigned gas supply line with a large throw distance, because this leads additional energy into the extraction tube and the ejected powder bell is evened out.
  • the high-pressure propellant gas is expediently reduced to the operating pressure in two stages.
  • the pressure reduction a high-pressure regulator and a low-pressure regulator, between which a pressure reducer is installed, which is connected on the input side to the charging line by means of a line and on the output side to the low-pressure regulator by means of a line.
  • the high-pressure propellant gas which is under 200 bar, can be reduced to 14 bar in the first stage and, for example, to 3 bar in the second stage.
  • a flush line is connected in the upper region of the container, which has a dust filter on the inside of the container and is connected to the consumers on the outside of the container via valves.
  • the flushing valves When the flushing valves are opened, the compressed gas in the container is released and the extinguishing powder is retained by means of the filter.
  • the consumer lines can thus be flushed by means of the compressed gas in the container.
  • the powder extinguishing system 16 essentially consists of the powder container 1, the high-pressure bottle 2 (an entire battery of bottles can also be provided), and the consumers 18, 19 and 20.
  • the consumer 18 is for a launcher tube and the consumers 19 and 20 provided for hose lines.
  • the container 1 is filled with the extinguishing powder 28.
  • a charging line 17 goes from the high-pressure bottle 2 into the container 1.
  • a pressure reduction 23 which consists of a low-pressure regulator 5, a high-pressure regulator 3 and an intermediate pressure reducer 4, this pressure reducer via lines 24 and 25 on the one hand with the Charging line 17 and on the other hand with the low pressure regulator 5 connected is.
  • a check valve 6 is provided in line 17.
  • two extraction tubes 21 and 22 are provided, a launcher tube 18 being arranged on the extraction tube 22 via a shut-off valve 9.
  • Hose lines 19 and 20 are provided on the extraction pipe 22 via valves 10 and 11.
  • a line 15 is provided, which is connected between the check valve 6 and the low pressure regulator 5 with the charging line 17 and is inserted into the lower end of the angled extraction tube 21.
  • a flushing line 26 is arranged, which is guided in the upper region into the container 1 and has a dust filter 27 there. Additional lines are provided via branch lines 26a and 26b, in which flushing valves 12, 13 and 14 are located.
  • an operating pressure manometer 8 and a safety valve 7 are provided in the container 1.
