Definitions

  • the invention relates to a method and a device for fire ventilation and fire containment by means of a combination of impulse ventilation with water mist injection.
  • impulse ventilation an air flow is generated by a jet of air at high speed by impulse transmission to the surrounding air.
  • the impulse ventilation is used as the state of the art for the ventilation of road and rail tunnels, as well as tunnels and garages, with the use of jet fans or Saccardodüsen.
  • the range of the water mist is increased, thereby can be applied to a larger area with less water injections compared to a pure water mist or sprinkler system
  • An apparatus consists of an arrangement of nozzles for water mist injection in the outlet jet of a jet fan, or a Saccardo nozzle.
  • uniformly distributed jet fans with water mist injection are to be provided over the entire length of the tunnel.
  • smaller fans can be used with lower blow-off speed, higher efficiency and lower connection performance.
  • the distance between the jet fans can be set to approx. 80 m. This is needed for effective pulse conversion.
  • the amount of injected water and the number, size and shape of the nozzles are designed to maintain the water mist concentration required for the required fire cooling along the entire length of a fire compartment (between two jet fans).
  • Jet fans are switched on in the direction of travel.
  • the valve of the first water mist injection is opened upstream of the fire location, i. in the
  • Outlet jet of the associated fan is injected water mist
  • the impulse ventilation is used as operating ventilation.

Abstract

L'invention concerne un procédé et un dispositif pour la ventilation et le confinement en cas d'incendie, en particulier dans les tunnels routiers ou ferroviaires, ainsi que dans les galeries et les parcs de stationnement, à l'aide d'une combinaison de ventilation pulsée et de projection d'un brouillard d'eau. Grâce à de hautes pressions et à une conception adéquate des buses, l'eau est pulvérisée en fines gouttes (installation de brouillard d'eau); la sortie de l'eau se fait dans la même direction que le jet d'air et la vitesse de sortie de l'eau est supérieure à la vitesse du jet d'air. De cette manière, on augmente à la fois l'impulsion du jet d'air et la portée du brouillard d'eau. L'incendie présent en aval du point d'injection est refroidi et confiné, les fumées sont traitées et lavées. Un dispositif selon l'invention se compose d'un agencement de buses pour la pulvérisation du brouillard d'eau dans le jet de sortie d'un ventilateur à jet.
