Abstract

The system has a case for supplying respirable air to two operators by flexible tubes of small diameter. The tubes are connected to the system by quick action couplings. Two independent turbines generate an adjustable air flow for the operators, where the air flow is sufficient to ensure necessary safety requirements for the operators while controlling main values of air quality in the event of risks involved during exceedance of carbon-di-oxide and carbon monoxide values from a range of values.

Description

ObjetObject

L'invention concerne un système d'adduction d'air pour masque de protection respiratoire.The invention relates to an air supply system for a respiratory protection mask.

Domaine techniqueTechnical area

Les domaines techniques pour lesquelles cette technologie est applicable sont :

  • Toutes les situations ou la qualité de l'air est de nature à mettre en danger la santé de l'opérateur, et ou les valeurs de la qualité de l'air ne respectent pas les normes en vigueur (VME), dans ces situations nous devons recourir à un apport d'air extérieur respirable.
The technical fields for which this technology is applicable are:
  • All situations where the quality of the air is likely to endanger the health of the operator, and where the values of the air quality do not respect the standards in force (VME), in these situations we must use a supply of breathable outside air.

Description de l'inventionDescription of the invention

Le système proposé est constitué d'un boitier qui alimente deux opérateurs en air respirable au moyen de tuyaux souple de petit diamètre relié au CUBAIR par des raccords rapides. Deux turbines indépendantes génèrent un débit d'air réglable aux opérateurs suffisant pour garantir toute la sécurité requise lors de travaux.The proposed system consists of a housing that supplies two operators with breathable air using small diameter flexible hoses connected to the CUBAIR by quick couplings. Two independent turbines generate an adjustable flow of air to the operators sufficient to guarantee all the safety required during work.

Le système est alimenté par du 230V / 8AThe system is powered by 230V / 8A

L'air est filtré au travers d'un pré filtre puis passe dans une chambre ou il est contrôlé au moyen de capteurs de CO et de CO2 calibré dans les valeurs limites fixées par les ordonnances en la matière.The air is filtered through a pre-filter and then goes into a room where it is controlled by means of CO and CO2 sensors calibrated in the limit values set by the relevant ordinances.

En cas de dépassement des valeurs CO et CO2 avec une marge de sécurité une procédure d'alarme et de mise en sécurité des opérateurs par une alarme et une coupure de l'apport d'air est activé, le système laisse aux opérateurs la possibilité de respirer, mais compte tenu que l'apport d'air n'est plus sous assistance, l'arrivée d'air est plus difficile, et par conséquent ils vont quitter la zone en toute sécurité.If the CO and CO2 values are exceeded with a margin of safety, an alarm procedure and the safety of the operators by an alarm and an air supply cut-off are activated, the system allows the operators the possibility to breathe, but since the supply of air is no longer under assistance, the air supply is more difficult, and therefore they will leave the area safely.

Le réglable du débit d'air de chaque turbine est indépendantThe adjustable airflow of each turbine is independent

Un système de sécurité concernant le débit minimal est activé pour informer par voyant lumineux et buser du manque d'air ou du débit trop bas.A minimum flow safety system is activated to inform by indicator light and to bus the lack of air or the flow rate too low.

Un débit minimum de 240 It/min est garanti pour chaque opérateur et pour une distance allant de 10 à 50 mètres entre le Cubair et les opérateurs.A minimum flow of 240 IT / min is guaranteed for each operator and for a distance ranging from 10 to 50 meters between the Cubair and the operators.

Le système est géré par un automate programmable qui permet un paramétrage des données, en fonction de l'adaptation aux besoins.The system is managed by a PLC that allows a data setting, according to the adaptation to needs.

Problèmes techniquesTechnical problems

Les problèmes rencontrés avec les systèmes actuellement sur le marché sont un appareillage gourmand en énergie plus de 380V / 34A contre 230v/8A pour la même utilisation.The problems encountered with the systems currently on the market are energy-saving equipment over 380V / 34A against 230V / 8A for the same use.

Un poids et une taille plus importante 300kg pour environ 1 m3 contre 25 Kg pour un carré de 35cm de côté (0.042m3)A weight and a larger size 300kg for about 1 m3 against 25 Kg for a square of 35cm side (0.042m3)

Un contrôle de la qualité d'air en continu est intégré dans le système proposé ce qui n'est pas le cas dans les systèmes trouvés sur le marché.Continuous air quality control is integrated into the proposed system, which is not the case in systems found on the market.

SolutionSolution

La solution Cubair à été évaluée par un laboratoire indépendant pour déterminer les caractéristiques sur chantiers et déterminer les valeurs minimales et idéales pour garantir la sécurité des opérateurs.The Cubair solution has been evaluated by an independent laboratory to determine the characteristics on building sites and to determine the minimum and ideal values to guarantee the safety of the operators.
