Definitions

  • the present invention relates to a method for optimizing a water spray extinguishing system, which is a water storage device, a pipe system connected to it having nozzles and a propellant to promote the water to the nozzles.
  • extinguishing parameters with thermodynamic and fluid mechanical Methods determined.
  • the first step is the development of the flue gas flow and the behavior of water drops emerging from a nozzle in this flue gas stream determined and from the relationships between drop speed, drop size and droplet evaporation become the properties necessary for the extinguishing Water drops calculated.
  • the system parameters are pressure, water flow and pipe dimensions so that the desired water drops are created.
  • the invention relates to a Water spray extinguishing system with a water storage device and one on this connected piping system with nozzles, with a through a propellant formed propellants to promote the water through the pipe system to the Nozzles, and with a means for reducing the pressure of the propellant.
  • the extinguishing system according to the invention is characterized in that the propellant gas is in one with the water storage device Gas pressure accumulator connected via a pressure line and that the Means for reducing the pressure of the propellant gas through one in this pressure line arranged aperture is formed.
  • a third preferred embodiment of the extinguishing system according to the invention is thereby characterized in that the pressure in the gas pressure accumulator is above 100 bar and preferably is 200 bar, and that the pressure in the pressure line after the orifice is less than 100 bar and is preferably between 10 and 40 bar.
  • this embodiment shows a schematic representation of an extinguishing system according to the invention, in which a blowing agent for the extinguishing water pressurized gas, such as nitrogen, is used.
  • a blowing agent for the extinguishing water pressurized gas such as nitrogen
  • the extinguishing system consists of a line system 1 with nozzles 2 which are provided for the discharge of extinguishing water in the form of droplets or spray mist.
  • the Fire-fighting water is stored in containers 3 of a water storage device 4, to which the line system 1 is connected.
  • the extinguishing system also assigns a propellant Conveying the water from the storage device 4 to the nozzles 2.
  • This blowing agent is a gas pressure accumulator 5 as shown.
  • the gas pressure accumulator 5 consists of a number of gas high-pressure bottles 6, in which, for example Nitrogen is stored under a pressure of 200 bar.
  • the high pressure gas cylinders 6 are connected via valves 7 to a pressure line 8 leading to the water storage device 4.
  • the pressure line 8 opens into the individual water tanks 3 and presses when acted upon with high pressure gas the water from the container 3 into the pipe system 1 and thus to the nozzles 2.
  • the pressure line 8 is acted upon by high pressure gas Opening the valves 7, which in the event of a fire by a corresponding signal from a fire alarm 9 or an extinguishing center 10 is triggered, in the latter case the extinguishing center 10 from Fire alarm 9 is activated. It goes without saying that the deletion process is triggered manually possible.
  • the pressure line 8 contains an orifice 11 in the area of the gas pressure accumulator 5 through which the delivery pressure in the pressure line 8 and thus also in the line system 1 an optimal nozzle pressure is throttled, for example in the range of about 10 to 40 bar.
  • the arrangement of the orifice 11 makes the critical flow phenomenon more compressible Media used by throttling to the delivery pressure during the extinguishing as possible to keep constant.
  • the discharge pressure changes only slowly and is guaranteed during the relevant ones Extinguishing or flooding phase an optimal nozzle pressure.
  • the through the bezel 11 caused pressure reduction leads to the fact that when opening the valves 7 in the line system 1 and no dangerous water hammer occurs at the nozzles 2.
  • the pipe system 1 and the water tank 3 materials which are not high pressure quality must have.
  • the orifice 11 is designed during the installation of the extinguishing system so that it touches the nozzles 2 sets the optimal pressure.
  • This interpretation takes place in the following way:
  • a first Step is made up of the dimensions of the space intended for the extinguishing system and a given fire determines the number and arrangement of the required nozzles 2 and Then the development of the fire gas flow, in particular the Ascent rate and temperature of the combustion gases depending on the burn rate, the burning quality, the fire area and the room height. With the help of these values the behavior of water drops after they emerge from the nozzles 2 is then described and the speed and evaporation of the drops are determined as a function of the room height and from this the optimal drop size and drop speed values for deletion certainly.
