Description

Dispositif réservoir bicaméral pour accroître la disponibilité et/ou la sécurité de fonctionnement d’un stockage de fluide.Bicameral reservoir device to increase the availability and/or operational safety of fluid storage.

La présente invention concerne un dispositif destiné à gérer le stockage d’un fluide dans des conditions de rendement et/ou sécurité de fonctionnement accrue.The present invention relates to a device intended to manage the storage of a fluid under conditions of increased efficiency and/or operational safety.

Le stockage d’un fluide est traditionnellement opéré dans une enceinte qui contient ce fluide à tout moment, même quand l’enceinte est supposée vide. Ceci est soit un inconvénient car une partie du fluide n’est pas utilisable, soit un danger dans le cas où le fluide est dangereux pour l’environnement de l’enceinte, par exemple lorsqu’il est inflammable ou corrosif.The storage of a fluid is traditionally carried out in an enclosure which contains this fluid at all times, even when the enclosure is assumed to be empty. This is either a disadvantage because part of the fluid is not usable, or a danger in the case where the fluid is dangerous for the environment of the enclosure, for example when it is flammable or corrosive.

Le dispositif objet de cette invention est une solution pour remédier à ces inconvénients et risques. Il comporte en effet principalement deux chambres communiquant entre elles. Des accessoires, tels que bouchons et capteurs de pression, de température, détecteur de présence par exemple, peuvent compléter le dispositif selon les applications et le résultat de l’analyse de sûreté de fonctionnement.The device that is the subject of this invention is a solution for remedying these drawbacks and risks. It has in fact mainly two rooms communicating with each other. Accessories, such as plugs and pressure and temperature sensors, presence detector for example, can complete the device depending on the applications and the result of the operational safety analysis.

La première chambre (CA), comporte d’une part un orifice communiquant (OA) avec le circuit d’exploitation du fluide appelé (FA). Cet orifice (OA) permet le remplissage de la chambre (CA) avec le fluide (FA) ainsi que sa vidange lorsque le fluide (FA) est exploité. D’autre part, elle contient un orifice communicant (Oc) avec la seconde chambre (Cc). La géométrie a priori optimale de la chambre (CA) est de révolution, mais elle peut également présenter des sections elliptiques ou gauches. La forme de l’intérieur de l’enceinte (E) de cette chambre (CA) est conçue et réalisée sans aspérité ni aucun arête ni angle vif, en particulier dans la zone de l’orifice communicant (Oc). A l’intérieur de cette chambre (CA) est installée une poche élastique (Ce).The first chamber (CA) comprises, on the one hand, an orifice communicating (OA) with the operating circuit of the called fluid (FA). This orifice (OA) allows the filling of the chamber (CA) with the fluid (FA) as well as its emptying when the fluid (FA) is used. On the other hand, it contains a communicating orifice (Oc) with the second chamber (Cc). The a priori optimal geometry of the chamber (CA) is of revolution, but it can also present elliptical or left sections. The shape of the interior of the enclosure (E) of this chamber (CA) is designed and produced without any roughness or any edge or sharp angle, in particular in the zone of the communicating orifice (Oc). Inside this chamber (CA) is installed an elastic pocket (Ce).

L’orifice communicant (Oc) est composé d’un ou plusieurs trous, proches les uns des autres dans ce cas. Disposer de plusieurs trous de relativement petite(s) section(s) est une solution pour que la poche élastique (Ce) soit plaquée sur l’orifice (Oc) sans être abîmée.The communicating orifice (Oc) is made up of one or more holes, close to each other in this case. Having several holes of relatively small section(s) is a solution so that the elastic pocket (Ce) is pressed against the orifice (Oc) without being damaged.

La seconde chambre (Cc) contient un gaz (Gc). Elle est équipée d’un bouchon d’accès (Be) placé sur un orifice (Oe) et destiné à des opérations d’entretien du dispositif.The second chamber (Cc) contains a gas (Gc). It is fitted with an access plug (Be) placed on an orifice (Oe) and intended for maintenance operations on the device.

Lorsque le fluide (FA) remplit la chambre (CA), la poche élastique (Ce) gonfle et occupe tout le volume de la chambre (CA), chassant le gaz (Gc) vers la chambre (Cc). La chambre (CA) est alors remplie du fluide (FA). Lorsque le fluide (FA) stocké dans la chambre (CA) est utilisé, la pression dans la chambre (CA) diminue. La poche élastique (Ce) se dégonfle sous l’effet de la pression du gaz (Gc) et vient reposer sur l’orifice (Oa). La chambre (CA) est alors remplie du gaz (Gc), vidée du fluide (FA). Ainsi le dispositif n’est plus dangereux pour l’environnement et tout le fluide (FA) stocké a été exploité.When the fluid (FA) fills the chamber (CA), the elastic pocket (Ce) swells and occupies the entire volume of the chamber (CA), driving the gas (Gc) towards the chamber (Cc). The chamber (CA) is then filled with the fluid (FA). When the fluid (FA) stored in the chamber (CA) is used, the pressure in the chamber (CA) decreases. The elastic bag (Ce) deflates under the effect of the gas pressure (Gc) and comes to rest on the orifice (Oa). The chamber (CA) is then filled with gas (Gc), emptied of fluid (FA). Thus the device is no longer dangerous for the environment and all the fluid (FA) stored has been exploited.

La poche élastique (Ce) est fabriquée dans une matière inerte et imperméable à la fois au fluide (FA) et au gaz (Gc). Sa géométrie dépend de la forme de la chambre (CA) et est définie de sorte que :The elastic bag (Ce) is made of an inert material that is impermeable to both fluid (FA) and gas (Gc). Its geometry depends on the shape of the chamber (CA) and is defined so that:

-d’une part, le gonflage est progressif le long des parois de la chambre (CA), éliminant toute zone dans laquelle serait piégée une quantité de gaz (Gc).-on the one hand, the inflation is progressive along the walls of the chamber (CA), eliminating any zone in which a quantity of gas (Gc) would be trapped.

-et d’autre part, la partie en contact avec l’orifice (Oc) résiste aux pressions du fluide (FA) et du gaz (Gc) ; cette partie est donc plus épaisse que les parties en contact avec les parois de la chambre (CA).-and on the other hand, the part in contact with the orifice (Oc) resists the pressures of the fluid (FA) and the gas (Gc); this part is therefore thicker than the parts in contact with the walls of the chamber (CA).

Cette poche élastique (Ce) est fixée sur l’orifice (OA) de sorte qu’elle soit aisément démontable pour l’entretien du dispositif.This elastic pocket (Ce) is fixed on the orifice (OA) so that it is easily removable for maintenance of the device.

La disposition des deux chambres (CA) et (Cc) est optimale lorsque celles-ci sont contiguës et superposées, avec une symétrie. Mais des contraintes géométriques peuvent imposer de les disposer autrement, par exemple, et sans que ce soit limitatif, sans symétrie, côte à côte, proches mais non contiguës ; dans ce dernier cas, une conduite de gaz (CGc) relie l’orifice (Oc) à la chambre (Cc).The layout of the two chambers (CA) and (Cc) is optimal when they are contiguous and superimposed, with symmetry. But geometric constraints may require them to be arranged differently, for example, and without this being limiting, without symmetry, side by side, close but not contiguous; in the latter case, a gas pipe (CGc) connects the orifice (Oc) to the chamber (Cc).

Le dispositif selon cette innovation peut être réalisé avec des chambres dont la forme générale est cylindrique, en acier inoxydable ; elles sont séparées par une unique pièce de forme arrondie et percée d’une dizaine de petits trous qui forme l’orifice communicant (Oc). La poche élastique (Ce) peut être fabriquée en caoutchouc.The device according to this innovation can be made with chambers whose general shape is cylindrical, in stainless steel; they are separated by a single piece of rounded shape and pierced with about ten small holes which form the communicating orifice (Oc). The elastic pocket (Ce) can be made of rubber.

Les figures annexées illustrent l’invention :The appended figures illustrate the invention:

-la représente en coupe les différents éléments du dispositif (la poche élastique (Ce) est représentée quand la chambre (CA) est partiellement remplie du fluide (FA)).-there shows in section the different elements of the device (the elastic pocket (Ce) is shown when the chamber (CA) is partially filled with the fluid (FA)).

-La représente, à titre d’illustration, 4 des nombreuses différentes dispositions des chambres : cylindrique contiguë ; dissymétrique proche ; dissymétrique côte-à-côte ; imbriquée.-There depicts, by way of illustration, 4 of the many different arrangements of the chambers: contiguous cylindrical; close asymmetrical; asymmetrical side-by-side; nested.

Le dispositif selon l’invention est destiné à être intégré dans un système complet d’exploitation d’un fluide. En particulier, il peut être destiné au stockage temporaire d’un gaz corrosif ou inflammable.The device according to the invention is intended to be integrated into a complete fluid exploitation system. In particular, it can be intended for the temporary storage of a corrosive or flammable gas.
