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

DISPOSITIF GENERATEUR DE BROUILLARD DESTINE NOTAMMENT A EQUIPER LES VEHICULES DE LUTTE CONTRE LES INCENDIES DANS LES TUNNELS 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, especially in 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 of the 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. II 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 the smoke from a fire, it is advantageous to create a barrier against the smoke using a cloud of droplets which forms a real barrier over a sufficient height and width. It is therefore necessary to rapidly implement a device allowing the production and the projection of jet of droplets arranged so as to preferably occupy 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 droplet jet 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 screen. at 180.

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 semicircular reservoir chamber from which extend telescopic tubes of variable lengths as required. In fact, the length of the telescopic tubes will be adapted to the needs of the problem. The reservoir 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 étanchéïté. On comprend que ces tubes qui s'elnboitent 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 l80 , On utilisera de préférence des buses à l80 pour les buses intermédiaires et l20 pour les buses installées à l'extrémité des tubes télescopiques. The telescopic tubes are equipped with O-rings allowing on the one hand an easy sliding and a perfect sealing. We understand that these tubes which fit into each other have a variable size according to the needs, these tubes have nozzles generating water mist distributed so as to create a screen at 180, We will preferably use nozzles to l80 for the intermediate nozzles and l20 for the 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 distribute the fog jets as well as possible, the telescopic tubes will be distributed over the tank like the spokes of half a bicycle wheel, at a distance from each other 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 most suitable fixing means, in particular for being fixed on 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. It is understood 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 device tank fills, the liquid loads the telescopic tubes which deploy and escape 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 water mist 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 mist of water so as to disturb the environment as little as possible, for example the atmosphere of a tunnel or a hangar, while preventing fumes and other aerosols. , to expand in 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 - contain smoke and thermal radiation, - reduce the spread of a chemical pollutant or micro-particles - protect and provide better safety for users and facilitate access by 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-telescopic tubes and be installed in fixed form.
