Definitions

  • the invention relates to a method and an arrangement for partitioning fire and smoke in structural systems. It is designed to effectively prevent the spread of fire, smoke and other potentially toxic fire products, in particular in those structures that are connected to one another or to an outside space via tunnel tubes.
  • the invention can be used in a particular way for the partitioning of tunnel openings in the railway system and for the protection of RoUtreppen Scheme at low-lying station facilities, such as especially subway stations, against higher lying areas. Structural openings in buildings and systems with fire protection
  • DE 195 14 923 proposes a method which produces the particle density and size required for this as a spray mist in such a way that extensive smoke, heat and pollutant binding takes place.
  • the method is primarily intended to reduce the high levels of smoke and pollutants that occur as a result of a fire and to keep any escape routes open, but not to prevent the spread of a fire source.
  • a liquid fire protection barrier is required, which is spread out like a water curtain in a vertical orientation over the entire profile of a tunnel-shaped opening to be protected.
  • a water curtain is known. This is formed from slot-shaped openings on the top of a passage. These openings are supplied with water from a tank and, when the openings are set appropriately, produce a stable film-like water curtain which is suitable for building up a certain protection against undesired gases.
  • Another possibility for the formation of a comparable water curtain is shown in JP 04319368. In it, gravity is used to drain water across the entire width of a room from a nozzle above it towards the floor.
  • the invention is therefore based on the object of providing a method and an arrangement with which a reliably sealed partitioning of tunnel-like structures, which cannot be interrupted by introduced obstacles, against the spread of fire, smoke and gaseous or particulate fire products and of radiant heat is ensured is.
  • the unhindered passage of people and objects should be ensured without opening the partition and there should be no impairment of the function of overhead line systems.
  • the water curtain which is constructed in a special way, is structurally composed of a large number of individual water droplets and not of a closed film. Incipient fire gases are captured by the turbulent, impulsive flow, adhere to the water droplets and are finally suppressed with the lowering water curtain. Due to the kinetic energy of the water droplets generated in all directions, the penetration of objects or people into the water curtain is completely irrelevant with regard to the criteria of a stable and continuously sealed seal against fire and smoke. The escaping water mist with its enormous surface is also able to absorb and compensate for heat radiation to a considerable extent. The effect is that on the protective side, behind an arrangement according to the invention that has been put into operation, after a so-called effective zone, no safety-relevant passage of heat and visible and invisible fire products such as smoke, fire gases and the like can be detected.
  • an effective zone of 10m is sufficient to be able to enter the adjoining area completely safely.
  • a significant advantage of the invention is also that, due to the composition of the water curtain from a large number of very small water droplets on live parts that are in the spray area or even directly inside the water curtain, no voltage breakdown occurs. Such evidence could even be provided on overhead line systems, which are usually operated at 15 kV at 16 2/3 Hz.
  • the arrangement according to the invention can thus also be used for tunnel systems which are used by railway vehicles if overhead lines for traction current are installed therein.
  • the water obtained during the spraying operation is collected and fed to a circuit, from which it is again conducted under pressure to the spray tube bend.
  • a circuit from which it is again conducted under pressure to the spray tube bend.
  • it can be supplied externally, for example from a sprinkler system that may be present or from the drinking water network. This also ensures that an increase in the temperature of the water in the circuit can be counteracted.
  • temperature monitoring or regulation is also available for this purpose.
  • the stability of the water curtain constructed with the agents according to the invention withstands air currents of up to approximately 5 m / s.
  • the system can be triggered via the output signal of a fire alarm control panel or directly via fire alarm sensors with the parameters smoke or heat.
  • Fig. 1 shows a schematic structure of an arrangement according to the invention
  • FIG. 2 shows a section of a spray pipe bend according to the invention with multiple nozzles arranged thereon and the structure of a water curtain
  • Fig. 3 shows a sectional view of a spray pipe bend with cover and spring-loaded locking mechanism
  • Fig. 4 shows a sectional view of a spray pipe bend with cover and pyrotechnically triggered locking mechanism
  • a spray pipe bend 2 with a nominal width DN 50 is introduced according to FIG. 1 in an area of a structural opening 1 to be protected in such a way that the side walls and the ceiling of the structural opening; voltage are each occupied with sections of the spray tube bend 2.
  • this first spray tube bend 2 is followed in parallel by a second, otherwise equally constructed spray tube bend 2.
  • Both spray tube bends 2 are accommodated separately in a U-shaped channel 17, which is provided with a cover 11.
  • the multiple nozzles 4 are aligned on the horizontally running regions of the spray tube bend 2 pivoted downwards by an angle of incidence 9 of 30 °, while the multiple nozzles 4 placed on the vertical regions of the spray tube bends 2 are inclined inwards by an angle of incidence 9 of 45 ° , All installation positions of the multiple nozzles 4 are selected such that they face the fire side 3 to be expected.
  • a collecting basin 7, which is covered with a grating, below an enlarged area around the installation position of the spray tube bends 2.
  • From the pool 7 leads a drainage system 14 to a storage container 8, the volume of which is adapted to the required amount of water in the structural opening 1 to be protected.
  • a supply system 15 leads from the reservoir 8 to the spray tube bend 2.
  • a pump 16 is located within the supply system 15.
  • the supply system 15 is also connected to an external water supply which, for example, is intended for feeding into an otherwise independently operating sprinkler system under different operating conditions ,
  • water is conveyed out of the storage container 8 and brought to the spray tube bend 2 by the pump 16 at an operating pressure of 8 bar.
  • the water passes through the spray tube bends 2 to all the multiple nozzles 4.
  • FIG. 2 how a water jet is generated in the multiple nozzles 4 by multiple deflection and is shaped such that it leaves the multiple nozzles 4 in a turbulent, turbulent manner, and in the process several hollow cones of fine water mist 5 intermeshing are formed.
  • a dense water curtain 6 extends over the entire cross section of the structural opening 1 and fills any gaps. This applies in particular to the area in the immediate vicinity of the multiple nozzles 4, where so-called blind spots are avoided.
  • this water curtain 6 As a result of the composition of this water curtain 6 from a large number of smallest water particles (water droplets), which essentially have a diameter of approximately 10 to 100 ⁇ m, an enormously large surface area is created which is suitable for absorbing considerable amounts of heat radiation generated on the fire side 3 , At the same time, the combustion gases used are also turbulent due to the kinetic energy produced within the water curtain 6, adhere to the water particles and are finally precipitated with the water curtain 6 being lowered. Because of the kinetic energy of the water particles generated uniformly in all directions, the penetration of objects or people into the water curtain 6 is completely irrelevant with regard to the criteria of a stable and continuously sealed partition against fire and smoke. You can also NEN live conductors 10 are within the structural opening 1, which also do not justify a reduction in the quality of the water curtain 6. In addition, there is no breakdown of electrical voltages, even if their size corresponds to the characteristic values of overhead line systems.
  • a water curtain 6 produced in this way has a high protective effect. Fires whose heat energy is approximately equivalent to that of a subway car that has caught fire are contained in their emissions to such an extent that, after an effective zone of around 10 meters, behind the spray tube bend 2 hazardous fire products are no longer detectable, with air currents up to a thickness of about 5 m / s, do not reduce the quality of the water curtain 6.
  • the continuously replenished and therefore also constantly decreasing water curtain 6 is collected by a collecting basin 7 below the floor level.
  • the collecting basin 7 is covered at the top with a grating.
  • the collected water is fed to the reservoir 8 and thus to the water cycle again via a filter system.
  • the water supply to the spray tube bends 2 takes place immediately after the release only via the storage container 8. Thereafter, at least part of the water required is obtained from an external feed, for example from a sprinkler system which is present in parallel. In addition, an optional feed via fire brigade connections is provided.
  • Both spray tube elbows 2 are accommodated separately in covered U-shaped channels 17 which are flung to the side when triggered.
  • the covers 1 1 are fixed on one side with hinges 18.
  • a spring-loaded locking mechanism 12 which is triggered electromechanically.

Abstract

L'invention concerne un procédé et un dispositif permettant d'interrompre la propagation du feu et de la fumée dans des constructions. Elle est destinée à empêcher efficacement la propagation du feu et de la fumée en particulier dans les installations qui sont reliées entre elles ou à un espace extérieur par des tubes de tunnel. Cette invention peut être mise en application en particulier pour cloisonner des ouvertures de tunnel de chemins de fer ou pour sécuriser des zones d'escaliers roulants dans des installations de gare routière par rapport à des zones situées à un niveau plus élevé. L'objectif de l'invention est de créer une cloison protégeant des constructions de type tunnel contre une propagation du feu, de la fumée ou d'autres produits du feu et contre la chaleur rayonnante, cette cloison étant étanche de manière fiable et ne cédant pas sous la charge d'obstacles. Par ailleurs, les personnes et les objets doivent pouvoir passer librement sans que la cloison soit ouverte. A cet effet, de l'eau est acheminée en permanence et sous haute pression à au moins deux tubes de pulvérisation en forme d'arcs qui suivent le bord supérieur et les bords latéraux de l'ouverture d'une construction et qui sont disposés à une certaine distance l'un de l'autre, puis l'eau tourbillonne et se disperse par impulsions sous forme de cônes creux de fines particules d'eau, ces cônes s'entrecroisant de façon décalée à plusieurs reprises, par l'intermédiaire de buses multiples disposées à intervalles réguliers et selon un angle d'inclinaison à l'inverse du côté prévu de l'incendie, de façon à former un rideau d'eau épais suivant le profil sur toute la section transversale.
