Abstract

The extractor has a suction ventilator (1) that allows passage of smoke coming from fumed particle filters (2). Temperature of hot gas is reduced by a cooling coil (3). The inert gases on fire plane are ejected towards outside by a vent-hole type pipe (4) or towards a collector. The pipe passes wall of facade of a building to permit direct ejection of smoke towards outside.

Description

DESCRIPTIONDESCRIPTION

L'appareil sera métallique ou tout autre matériau équivalent en résistance au feu. L'Extracteur Autonome de Désenfumage sera composé d'éléments distincts qui seront soit regroupés dans un même corps, soit démembrés mais raccordés par une gaine présentant les caractéristiques de résistance au feu.  The device will be metallic or any other equivalent material in fire resistance. The Autonomous Smoke Extractor will be composed of separate elements that will be either grouped in the same body, or dismembered but connected by a sheath with the characteristics of fire resistance.

Ces éléments sont: - un avaloir des fumées, - un ensemble de filtres pièges à particules de fumées, - un circuit de refroidissement (en option), - un ventilateur, élément de raccordement et de rejet sur l'extérieur.  These elements are: - a flue gas trap, - a set of trap filters with smoke particles, - a cooling circuit (optional), - a fan, connecting element and rejection on the outside.

En cas d'incendie dans le volume concerné, l'extracteur sera actionné, soit manuellement, soit automatiquement.  In case of fire in the volume concerned, the extractor will be activated, either manually or automatically.

Le débit d'extraction ainsi que la vitesse seront conformes aux spécifications de l'Ins-15 truction Technique 246 relative au désenfumage dans les établissements recevant du public.  The extraction flow rate and the speed will be in accordance with the specifications of Technical Instruction 246 on smoke extraction in establishments open to the public.

Les gaz seront aspirés dans un collecteur de refroidissement par un ventilateur incorporé qui assurera l'extraction de l'ensemble et le soufflage des gaz filtrés vers l'extérieur par un conduit de faible dimension de type ventouse, ou vers un collecteur encoffi é débouchant sur l'extérieur.  The gases will be sucked into a cooling manifold by a built-in fan which will ensure the extraction of the assembly and the blowing of the filtered gases to the outside by a small duct of sucker type, or to a collector encoffi resulting in outside.

En option (dans le cas où les rejets à haute température risquent de menacer des éléments de construction) les gaz chauds sont rabaissés en température par un système de brumisateur ou de serpentin de refroidissement.  As an option (in the case where high temperature rejects may threaten building elements) the hot gases are lowered in temperature by a mist or cooling coil system.

Le caisson contiendra les préfiltres et filtres qui piégeront les particules de combustion. L'amenée d'air s'effectuera classiquement par des prises d'air directes sur l'extérieur.  The box will contain the prefilters and filters that will trap the combustion particles. The air supply will be carried out conventionally by direct air intakes on the outside.

PRÉAMBULE Les contraintes normatives et réglementaires, ainsi que l'analyse de risque dans les établissements débouchent très fréquemment sur l'installation d'équipement visant à 30 améliorer la sécurité incendie.  PREAMBLE Normative and regulatory constraints, as well as risk analysis in institutions, very frequently lead to the installation of equipment aimed at improving fire safety.

Dans ces équipements figurent notamment les matériels de désenfumage.  This equipment includes smoke extraction equipment.

OBJECTIFGOAL

Le désenfumage a pour objet de: - évacuer les gaz chauds de combustion lors d'un incendie, - limiter les propagations, - assurer la vacuité des dégagements - permettre l'intervention des secours dans des conditions améliorées, sur le mode naturel ou mécanique.  Smoke extraction is intended to: - evacuate the hot combustion gases during a fire, - limit the spread, - ensure the vacuity of the clearances - allow the intervention of rescue under improved conditions, in the natural or mechanical mode.

Les différentes réglementations imposent pour chaque type d'activité, et selon la nature des locaux, un mode de désenfumage prédéfini.  The different regulations require for each type of activity, and according to the nature of the premises, a predefined smoke extraction mode.

Ainsi, dans les établissements hospitaliers et les bâtiments d'hébergement de personnes âgées ou handicapées, un désenfumage mécanique est strictement imposé.  Thus, in hospitals and accommodation buildings for the elderly or disabled, mechanical smoke extraction is strictly imposed.

PROBLÉMATIQUE La mise en place d'un système de désenfumage dans un établissement existant pose 15 plusieurs problèmes: Le percement de trémies dans les planchers existant afin d'édifier verticalement des conduits d'amenées d'air et d'extraction.  PROBLEM The establishment of a smoke extraction system in an existing establishment poses several problems: The drilling of hoppers in existing floors in order to vertically build air intake and extraction ducts.

La localisation imposée des conduits par les contraintes de distances entraîne une perturbation dans l'organisation des locaux et une perte de surface utile.  The imposed localization of the ducts by the constraints of distances causes a disturbance in the organization of the premises and a loss of useful surface.

L'installation des moteurs de désenfumage placés spécifiquement dans des locaux adaptés et isolés entraîne des sujétions lourdes de localisation et de mise en place.  The installation of smoke evacuation engines placed specifically in adapted and insulated premises leads to heavy constraints of location and placement.

MATÉRIEL INVENTÉ Le matériel dénommé Extracteur Autonome de DésenFumage a pour objet d'assurer l'évacuation et le filtrage des fumées de façon locale en évitant le raccordement à des conduits verticaux de forte section.  MATERIALS INVENTED The purpose of the equipment known as Autonomous Smoke Removal Extractor is to ensure the evacuation and the filtering of fumes locally by avoiding the connection to vertical ducts with a large section.

-3 REVENDICATION-3 CLAIM 1) Dispositif prévu pour évacuer les fumées d'incendie de façon autonome sans raccordement à un conduit collectif caractérisé en ce qu'il comporte - Un ventilateur d'aspiration (1) qui avale les fumées; celles-ci passant par des filtres à particules de fumée (2).  1) Device designed to evacuate the fire fumes independently without connection to a collective conduit characterized in that it comprises - A suction fan (1) which swallows the fumes; these passing through smoke filters (2). En option (dans le cas où les rejets à haute température risquent de menacer des éléments de construction) les gaz chauds sont rabaissés en température par un système de brumisateur ou de serpentin de refroidissement (3).  As an option (in the case where high temperature rejects may threaten building elements) the hot gases are lowered in temperature by a mist or cooling coil system (3). - Les gaz divers inertes sur le plan de l'incendie sont rejetés sur l'extérieur par un conduit de faible dimension type ventouse (4) ou vers un collecteur encoffré débouchant 10 sur l'extérieur.  - The various gases inert in terms of fire are rejected on the outside by a duct of small size suction cup (4) or to a manifold collector opening 10 on the outside.
