Abstract

The water fog generator for fighting tunnel fires is mounted on a rescue vehicle for fire fighting to form a screen of fog jets to dampen smoke and flames in a tunnel. The jets create a one hundred and eighty degree screen to counter the effects of fire. It has a semi-circular shaped tank from which telescopic tubes extend to carry the fog jet nozzles. The tank is connected to as pressurized fluid source.

Description

La présente invention est relative à un dispositif pour la production d'un jet de gouttelettes d'eau, afin que ce jet crée un rideau de brume constituant, notamment, un moyen de lutte contre les fumées issues d'un incendie, les poussières atmosphériques, les aérosols toxiques, les « nuages de gaz », les fumées ou nuages pulvérulents, notamment dans les tunnel.The present invention relates to a device for producing a jet of water droplets, so that this jet creates a curtain of mist constituting, in particular, a means of combating smoke from a fire, atmospheric dust, toxic aerosols, "gas clouds", smoke or powdery clouds, in particular in the tunnels.

Le dispositif selon l'invention a été mis au point au cours d'études pour la mise en oeuvre des procédés de brouillard d'eau décrits notamment dans les documents FR6A62.624.750 et 2.672.808.The device according to the invention was developed during studies for the implementation water mist processes described in particular in documents FR6A62.624.750 and 2,672,808.

Lorsqu'on veut lutter, en particulier, contre les fumées d'un incendie, il est avantageux de créer un barrage contre les fumées à l'aide d'un nuage de gouttelettes qui forme une véritable » barrière » sur une hauteur et une largeur suffisante. Il est donc nécessaire de mettre rapidement en oeuvre un dispositif permettant la production et la projection de jet de gouttelettes disposées de façon à occuper de préférence 180°.When you want to fight, in particular, against smoke from a fire, it is advantageous to create a smoke barrier using a cloud of droplets which forms a real "barrier" over a sufficient height and width. It is therefore necessary to quickly implement a device allowing the production and the projection of jet droplets arranged so as to occupy preferably 180 °.

La présente invention a pour but non seulement d'augmenter considérablement la sécurité mais aussi de faciliter grandement la rapidité de mise en oeuvre, ce qui est primordial pour ce type de dispositif d'urgence.The object of the present invention is not only to considerably increase security but also to greatly facilitate the speed of implementation, which is essential for this type of emergency device.

Pour obtenir ce résultat, l'invention fournit un dispositif pour la production de jet de gouttelettes permettant la création d'un véritable écran, le dispositif de l'invention comprenant une série de moyens de projection de jets gouttelettes disposées de façon à créer un écran à 180°.To obtain this result, the invention provides a device for producing a jet of droplets allowing the creation of a real screen, the device of the invention comprising a series of means for projecting droplet jets arranged so as to create a 180 ° screen.

Ce dispositif est constitué d'une chambre réservoir en demi-cercle depuis laquelle partent des tubes télescopiques de longueurs variables selon les besoins. En effet on adaptera la longueur des tubes télescopiques aux besoins du problème. Le réservoir est relié à une source de liquide sous pression.This device consists of a semicircle reservoir chamber from which depart telescopic tubes of varying lengths as required. Indeed we will adapt the length of the telescopic tubes to the needs of the problem. The tank is connected to a source of pressurized liquid.

Les tubes télescopiques sont équipés de joints toriques permettant d'une part un coulissement aisé et une parfaite étanchéité. On comprend que ces tubes qui s'emboitent les uns dans les autres ont une taille variable selon les besoins, ces tubes comportent des buses génératrices de brouillard d'eau réparties de façon à créer un écran à 180° , On utilisera de préférence des buses à 180° pour les buses intermédiaires et 120° pour les buses installées à l'extrémité des tubes télescopiques. The telescopic tubes are fitted with O-rings allowing on the one hand a easy sliding and perfect sealing. We understand that these tubes which fit together in each other have a variable size according to the needs, these tubes include nozzles generating water mist distributed so as to create a 180 ° screen, On preferably use 180 ° nozzles for intermediate nozzles and 120 ° for nozzles installed at the end of the telescopic tubes.

Afin de répartir au mieux les jets de brouillard les tubes télescopiques seront répartis sur le réservoir comme les rayons d'une moitié de roue de bicyclette, à une distance les un des autres suffisante pour qu'ils ne se gênent pas entre eux.In order to best distribute the mist jets, the telescopic tubes will be distributed over the tank like the spokes of a half of a bicycle wheel, at a distance one others sufficient so that they do not interfere with each other.

L'invention prévoit que le dispositif soit équipé des moyens de fixations les mieux adaptés, notamment pour être fixées sur un véhicule routier ou ferroviaire.The invention provides that the device is equipped with the best fixing means adapted, in particular to be fixed to a road or rail vehicle.

On conçoit que la fabrication, l'installation et la mise en oeuvre du dispositif est facile, une fois mis en place à demeure, ou selon les besoins, le dispositif une fois raccordé par une canalisation au réservoir du véhicule ou à une autre source de liquide sous pression, une vanne manuelle ou automatique, permet la mise en charge du dispositif, le réservoir du dispositif se remplit, le liquide met en charge les tubes télescopiques qui se déployent et s'échappe sous forme de jets de gouttelettes au travers des buses qui équipent les tubes. Une fois déployé le dispositif ressemble à une sorte d'éventail générant un brouillard d'eau formant rideau.We understand that the manufacture, installation and implementation of the device is easy, once permanently installed, or as required, the device once connected by a pipe to the vehicle tank or to another source of pressurized liquid, a manual or automatic valve, allows the device to be loaded, the tank of the device fills, the liquid loads the telescopic tubes which deploy and escapes in the form of jets of droplets through the nozzles which equip the tubes. Once deployed the device looks like a sort of fan generating a fog of water forming a curtain.

L'objet principal de la présente invention est de pouvoir générer un brouillard d'eau de façon à perturber le moins possible le milieu, par exemple l'atmosphère d'un tunnel ou d'un hangar, tout en empêchant les fumées et autres aérosols, de s'expanser dans le volume.The main object of the present invention is to be able to generate a water mist of so as to disturb the environment as little as possible, for example the atmosphere of a tunnel or of a hangar, while preventing smoke and other aerosols, from expanding in the volume.

Dans le cas d'un incendie de tunnel par exemple le dispositif permettra :

  • de contenir les fumées et le rayonnement thermique,
  • de réduire la propagation d'un polluant chimique ou de micro-particules
  • de protéger et assurer en meilleure sécurité les usagers et faciliter l'accès des services de secours.
In the case of a tunnel fire, for example, the device will:
  • to contain smoke and thermal radiation,
  • reduce the spread of a chemical pollutant or micro-particles
  • protect and provide better security for users and facilitate access to emergency services.

On comprend aisément que ce type de dispositif peut être réaliser avec des tubes non télescopiques et être installé sous forme fixe.It is easily understood that this type of device can be produced with non-tubing telescopic and be installed in fixed form.
