Definitions

  • the invention relates to a method and a device for atomizing liquid extinguishing agent in the finest drops in stationary extinguishing systems.
  • Sprinkler, foam, water spray and gas extinguishing systems are usually used.
  • the object of the invention was to reduce the amount of liquid extinguishing agent required for fire extinguishing in stationary deluge systems. This object is achieved in that inert gas is added to the liquid extinguishing agent.
  • inert gas here does not refer to the state of matter at the time of addition to the liquid extinguishing agent, but the inert gas can be added to the liquid extinguishing agent in liquid or gaseous form.
  • the inert gas can be added either by admixing the inert gas with increased pressure to the extinguishing agent or the extinguishing agent with increased pressure to the inert gas.
  • the liquid extinguishing agent water is usually carried out in the network at a pressure of 8-10 bar, regardless of the water supply, such as. B. city water network, tanks, etc.
  • the inert gas is fed into the pipeline network at an increased pressure.
  • suitable admixing devices and devices for controlling the pressure in the line network such as. B. check valve, shut-off valve, control valve for the media, to a pressure increase in devices for dispensing the liquid extinguishing agent, for. B. extinguishing nozzles. This increases not only the water outlet speed at the extinguishing nozzles, but also the drop distribution and the throwing distance.
  • Drop sizes and throwing distances can be influenced by different nozzles, in particular throwing distances of up to 10 m or microdroplets can be achieved at the nozzle.
  • Another considerable advantage is that the inert gas partially dissolves in the liquid extinguishing agent under high pressure and is thus brought to the source of the fire with the droplets generated, since the dynamic process of degassing takes longer than the transport time. This leads to an improvement in the extinguishing effect, with the advantage that hidden fires can also be extinguished better.
  • the flame is separated from the combustible gas by the kinetic energy of the liquid extinguishing agent and by the degassing of the inert gas at the location of the fire by the process according to the invention.
  • the surface area of the liquid extinguishing agent is considerably enlarged by the formation of microdroplets in the area of the fire, in particular by the segregation of liquid extinguishing agent and inert gas.
  • the inert gas e.g. CO 2
  • CO 2 absorbed additional radiation energy
  • the evaporation of the liquid extinguishing agent removes energy from the fire.
  • the excess of energy in the fire area is reduced to such an extent that a high extinguishing effect is achieved which cannot be achieved by using microdroplets alone without adding inert gas.
  • Water is preferably added as the inert gas CO 2 to the liquid extinguishing agent.
  • the amount of inert gas added is optimized. If CO 2 is used , this can either be done during project planning by specifying a maximum amount of CO 2 in relation to the extinguishing object. However, it is preferred that the amount of inert gas added, particularly CO 2, is regulated as a function of the concentration in the extinguishing area during the extinguishing.
  • the amount of inert gas added is additionally regulated according to the course of the fire.
  • a device which, in addition to a supply for liquid extinguishing agent and dispensing devices for liquid extinguishing agent, is characterized in that at least one reservoir for inert gas and at least one admixing unit is provided for mixing liquid extinguishing agent and inert gas.
  • the admixing unit is located in front of (upstream from) the nozzle devices
  • At least one detector for determining the concentration of the inert gas in the extinguishing area is preferably connected to the device with at least one evaluation device, and this with at least one control device for regulating the amount of the inert gas.
  • This detector can form a unit with the detector for determining the concentration of the inert gas in the extinguishing area and can be designed in particular as a combined measuring device for electromagnetic radiation and on the principle of smoke detectors and heat detectors.
  • the opening angles of the dispensing devices for liquid extinguishing agent can be adjusted, the opening angle being determined by the amount of inert gas added.
  • the device according to the invention has a check valve 9.
  • the extinguishing water is mixed with the CO 2 flowing out of the reservoir 2.
  • Suitable shut-off devices and a control valve 8 are arranged between the reservoir 2 and the admixing unit 3.
  • the control valve is preferably connected to an evaluation device 7 for a detector 6 for the extinguishing nozzles 5 defining the extinguishing area 4.
  • the shut-off devices are e.g. B. opened via a fire alarm system, not shown, and after a delay, depending on the water supply, the control valve 8 is switched.
  • This circuit can switch the control valve 8 to intermittent or continuous flow in order to clear the way for the CO 2 as a pressure increasing and inerting medium.
  • the system automatically regulates itself to intermittent operation when the control valve 8 is open. In this case, an evaluation device 7 is not absolutely necessary.
  • the extinguishing nozzles 5 have z. B. has a spring-loaded valve seat, which, depending on the pressure at the nozzle in conjunction with a cone at the outlet opening of the nozzle, enables the opening angle to be adjusted.
  • the pressure at the nozzle can be set by the amount of extinguishing agent delivered to the mixer per unit of time.
  • the pressure increase by adding the CO 2 can, starting from 8-10 bar, preferably take place to a total pressure of 35-60 bar.
  • the amount of CO 2 released into the extinguishing area 4 remains below the toxicity limit.
  • the water initially emerges as a jet when it leaves the pipe system and is broken down into the finest drops only on the flight to the source of the fire, which results in larger throwing distances, or it emerges as the finest drops with a short range.
  • a possible icing problem in the CO 2 supply line must be prevented by known measures.
