Description

La présente invention concerne une barrière de protection pour un équipement industriel.The present invention relates to a protective barrier for industrial equipment.

Des barrières anti-feu et /anti-projections de métal fondu et/ou anti-fragments sont utilisées dans les installations industrielles où est présent de l'oxygène ou au moins un fluide combustible, tels que l'hydrogène, le méthane, l'acétylène, l'ammoniac, le propane, le propylène.Anti-fire and/anti-splash of molten metal and/or anti-fragment barriers are used in industrial installations where oxygen or at least one combustible fluid is present, such as hydrogen, methane, acetylene, ammonia, propane, propylene.

Ces barrières peuvent être en béton, béton armé, acier ou ciment.These barriers can be made of concrete, reinforced concrete, steel or cement.

Par exemple, les appareils de séparation de l'air ou d'autres mélanges gazeux par distillation cryogénique fonctionnent à des pressions élevées et sont reliés à des équipements potentiellement dangereux où circulent un fluide combustible ou de l'oxygène. Ces équipements doivent être protégés par des barrières. Le but principal d'une barrière de sécurité est de prévenir les accidents du personnel. Un objectif secondaire est de prévenir ou de réduire les dommages aux équipements adjacents. Les barrières liées aux services d'oxygène ou hydrogène sont particulièrement importantes. Les incendies et / ou explosions d'oxygène sont très différents en température et en intensité que ceux d'une raffinerie de pétrole ou d'une usine pétrochimique. Dans les incendies de raffinerie ou de pétrochimie, le carburant est au moins un hydrocarbure qui s'échappe à travers le métal comme les tuyaux et les réservoirs, et les températures peuvent atteindre jusqu'à 980°C. Dans un incendie à oxygène, le carburant est lui-même du métal. Ces incendies produisent à des températures extrêmement élevées de 3000°C et plus.For example, devices for separating air or other gas mixtures by cryogenic distillation operate at high pressures and are connected to potentially dangerous equipment where a combustible fluid or oxygen circulates. This equipment must be protected by barriers. The main purpose of a safety barrier is to prevent personnel accidents. A secondary objective is to prevent or reduce damage to adjacent equipment. The barriers linked to oxygen or hydrogen services are particularly important. Oxygen fires and/or explosions are very different in temperature and intensity than those in an oil refinery or petrochemical plant. In refinery or petrochemical fires, the fuel is at least one hydrocarbon that escapes through metal such as pipes and tanks, and temperatures can reach up to 980°C. In an oxygen fire, the fuel itself is metal. These fires produce at extremely high temperatures of 3000°C and above.

Ainsi, en général, il existe trois types de forces mécaniques à prendre en compte dans la conception d'une barrière: (i) force d'un jet résultant d'un dégagement de fluide compressible à partir d'un trou dans un carter de compresseur ou une tuyauterie accompagnée de métal fondu issu d'un trou, (ii) une surpression ou une force de souffle résultant d'une libération massive d'énergie stockée, comme un stockage d'oxygène ou de gaz de combustion chauds, et (iii) une force résultant de l'impact de fragments d'acier projetés à une vitesse élevée en raison de une explosion. En outre, la conception d'une barrière de sécurité pour résister à un feu d'oxygène doit lui permettre de résister à des charges thermiques de 3000°C à l'emplacement de la combustion métallique et des éclaboussures de métal fondu. « Oxygen Compressor Installation and Operation Guide, a standard for current industrial practices for oxygen compresser installations, operations, maintenance, and safety, publication number G-4.6 (1992) » publié par Compressed Gas Association ("CGA"), 4221 Walney Road, 5th Floor, Chantilly, Va. 20151-2923 Doc 10/17 décrit une enceinte pour un compresseur d'oxygène, l'enceinte ayant des parois verticales d'une hauteur minimale de 2,4 m, à ciel ouvert ou ayant un toit partiel. Ce document souligne l'importance de la ventilation pour éviter la concentration d'oxygène autour du compresseur et suggère que le fait que l'enceinte soit à ciel ouvert suffit pour assurer cette ventilation.Thus, in general, there are three types of mechanical forces to consider in the design of a barrier: (i) force of a jet resulting from a release of compressible fluid from a hole in a casing of compressor or piping accompanied by molten metal from a hole, (ii) an overpressure or blast force resulting from a massive release of stored energy, such as storage of oxygen or hot combustion gases, and ( iii) a force resulting from the impact of steel fragments projected at high speed due to an explosion. Additionally, designing a safety barrier to withstand a fire of oxygen must enable it to withstand thermal loads of 3000°C at the location of metal combustion and splashes of molten metal. “Oxygen Compressor Installation and Operation Guide, a standard for current industrial practices for oxygen compressor installations, operations, maintenance, and safety, publication number G-4.6 (1992)” published by Compressed Gas Association (“CGA”), 4221 Walney Road, 5th Floor, Chantilly, Va. 20151-2923 Doc 10/17 describes an enclosure for an oxygen compressor, the enclosure having vertical walls with a minimum height of 2.4 m, open to the sky or having a partial roof. This document highlights the importance of ventilation to avoid the concentration of oxygen around the compressor and suggests that the fact that the enclosure is open to the sky is sufficient to ensure this ventilation.

Un but de la présente invention est de réduire la distance à laquelle des fragments et/ou du métal fondu peuvent être projetés suite à une explosion et/ou de limiter la propagation d'une flamme. De cette façon, il devient possible de disposer d'autres équipements et/ou d'autoriser la présence d'une personne plus proches de la barrière sans risque sécuritaire.An aim of the present invention is to reduce the distance at which fragments and/or molten metal can be projected following an explosion and/or to limit the propagation of a flame. In this way, it becomes possible to have other equipment and/or authorize the presence of a person closer to the barrier without security risk.

Selon un autre but de l'invention, il est prévu d'améliorer la ventilation à l'intérieur de la barrière.According to another aim of the invention, it is planned to improve ventilation inside the barrier.

[Fig.1] montre une coupe d'une barrière de protection pour un équipement industriel E. L'équipement industriel E peut être parcouru par un fluide (gaz ou liquide) combustible ou de l'oxygène gazeux ou liquide. Il peut aussi traiter le fluide en question. L'équipement E peut par exemple être un compresseur, une pompe, une vanne, une conduite ou un stockage. La pression du fluide en question peut être au-dessus d'un bara, ou au-dessus de 10 bara ou au-dessus de 50 bara.[ Fig.1 ] shows a section of a protective barrier for industrial equipment E. Industrial equipment E can be traversed by a combustible fluid (gas or liquid) or gaseous or liquid oxygen. It can also treat the fluid in question. The equipment E can for example be a compressor, a pump, a valve, a pipe or storage. The pressure of the fluid in question may be above one bara, or above 10 bara, or above 50 bara.

La barrière comprend quatre parois verticales 1,2,3,4 formant quatre côtés d'un parallélépipède fixées à un socle S pour définir un espace à section rectangulaire destiné à contenir l'équipement industriel E disposé sur le socle S. Ici on voit les parois 1, 2 ayant la même hauteur. La paroi 4 formerait le fond de la coupe mais n'est pas illustré. Les quatre parois verticales 1,2,3,4 sont en béton armé ou autre matériel adapté (acier, ciment, béton) et ont une hauteur d'au moins 2, 4m. Dans la coupe, on voit les parois 1, 2 définissant la longueur d'espace, les parois 3,4 en définissant la largeur W. Le rapport entre la largeur et la longueur peut avoir n'importe laquelle valeur. L'espace parallélépipédique entre les parois 1,2,3,4 et le socle est partiellement fermé sur le dessus par un toit partiel T1 fixé à trois des parois verticales 1,3,4. Le toit T1 est une plaque, en béton armé ou autre matériel adapté (acier, ciment, béton) et a une surface rectangulaire parallèle au socle S et perpendiculaire aux parois1,2,3,4, la surface du toit partiel T1 correspondant à au plus la moitié de la section rectangulaire de l'espace formé par les quatre parois 1,2,3,4. La largeur de la plaque du toit T1 est W1 et sa longueur est celle des parois 1, 2. Le toit partiel se trouve au-dessus de l'équipement E laissant un espace ouvert de largeur WA et de longueur égale celle des parois 1, 2.The barrier comprises four vertical walls 1,2,3,4 forming four sides of a parallelepiped fixed to a base S to define a space with a rectangular section intended to contain the industrial equipment E placed on the base S. Here we see the walls 1, 2 having the same height. Wall 4 would form the bottom of the cup but is not illustrated. The four vertical walls 1,2,3,4 are made of reinforced concrete or other suitable material (steel, cement, concrete) and have a height of at least 2.4m. In the section, we see the walls 1, 2 defining the length of space, the walls 3,4 defining the width W. The ratio between the width and the length can have any value. The parallelepiped space between the walls 1,2,3,4 and the base is partially closed on top by a partial roof T1 fixed to three of the vertical walls 1,3,4. The roof T1 is a plate, made of reinforced concrete or other suitable material (steel, cement, concrete) and has a rectangular surface parallel to the base S and perpendicular to the walls1,2,3,4, the surface of the partial roof T1 corresponding to plus half of the rectangular section of the space formed by the four walls 1,2,3,4. The width of the roof plate T1 is W 1 and its length is that of the walls 1, 2. The partial roof is above the equipment E leaving an open space of width W A and of length equal to that of the walls 1, 2.

W1 est égal au plus à 50% de W et WA est égal au moins à 50% de W.W 1 is equal to at most 50% of W and W A is equal to at least 50% of W.

A côté de la barrière se trouve un appareil industriel B sur lequel peut travailler une personne. On voit que la barrière est dimensionnée de sorte que le cône parcouru par les fragments ou le feu provenant de l'équipement E ne peut atteindre la personne ou l'appareil B. Ici l'équipement industriel est sur le même socle S, ceci n'est pas essentiel. L'appareil B peut être une colonne de distillation ou un stockage et ici est plus haut que la barrière, donc plus haut qu'au moins 2,4 m.Next to the barrier is an industrial device B on which a person can work. We see that the barrier is sized so that the cone traversed by the fragments or the fire coming from the equipment E cannot reach the person or device B. Here the industrial equipment is on the same base S, this is not essential. Device B can be a distillation column or storage and here is higher than the barrier, therefore higher than at least 2.4 m.

Le socle S ne s'étend pas nécessairement au-delà de la barrière et l'appareil peut se trouver sur un autre socle.The S base does not necessarily extend beyond the barrier and the device may be on another base.

Un opérateur peut agir sur l'équipement à travers les manettes passant dans une paroi de la barrière. Ainsi l'opérateur reste à l'extérieur de la barrière.An operator can act on the equipment through the levers passing through a wall of the barrier. Thus the operator remains outside the barrier.

[Fig.2] montre de manière plus détaillée la distance D entre la paroi 1 de la barrière de hauteur H et l'appareil B. Sans la présence du toit partiel T1 de largeur WT, le feu et/ou les fragments provenant de E attendraient une zone de l'appareil B en dessous de la hauteur M. La paroi 2 n'est pas illustrée pour simplifier le dessin.[ Fig.2 ] shows in more detail the distance D between the wall 1 of the barrier of height H and the device B. Without the presence of the partial roof T1 of width W T , the fire and/or the fragments coming from E would wait for a zone of device B below height M. Wall 2 is not illustrated to simplify the drawing.

[Fig.3] montre la même coupe que la [Fig.1] mais vue dans l'autre sens avec la paroi 3 au fond.[ Fig.3 ] shows the same cut as the [ Fig.1 ] but seen in the other direction with wall 3 at the bottom.

[Fig.4] montre une coupe d'une barrière de protection pour quatre équipements industriels dont deux illustrés ici E, E1. Les équipements industriels peuvent être parcourus par le même fluide (gaz ou liquide) combustible ou de l'oxygène gazeux ou liquide ou peuvent être parcourus par des fluides différents (combustible ou oxygène). Ils peuvent aussi traiter le fluide en question. Les équipements peuvent être choisis dans la liste suivante non exhaustive : un compresseur, une pompe, une vanne, une conduite ou un stockage. La ou les pressions du fluide ou des fluides en question peut être ou peuvent être au-dessus d'un bara, ou au-dessus de 10 bara ou au-dessus de 50 bara.[ Fig.4 ] shows a section of a protective barrier for four industrial equipment, two of which are illustrated here E, E 1 . Industrial equipment can be filled with the same combustible fluid (gas or liquid) or gaseous or liquid oxygen or can be filled with different fluids (fuel or oxygen). They can also treat the fluid in question. The equipment can be chosen from the following non-exhaustive list: a compressor, a pump, a valve, a pipe or storage. The pressure(s) of the fluid(s) in question may be above one bara, or above 10 bara, or above 50 bara.

La barrière comprend quatre parois verticales 1,2,3,4 formant quatre côtés d'un parallélépipède fixées à un socle S et divisés par des cloisons C pour définir un espace à section rectangulaire divisé en quatre compartiments identiques ou pas destinés à contenir chacun un équipement industriel E. Chacun de ces compartiments est considéré comme formant une barrière pour l'équipement qu'il contient. Ici on voit les parois 1, 2 ayant la même hauteur. Les quatre parois verticales 1,2,3,4 sont en béton armé ou autre matériel adapté et ont une hauteur H d'au moins 2, 4m. Dans la coupe, on voit les parois 1, 2 définissant la longueur d'espace, les parois 3,4 en définissant la largeur 2W. Le rapport entre la largeur et la longueur peut avoir n'importe laquelle valeur.The barrier comprises four vertical walls 1,2,3,4 forming four sides of a parallelepiped fixed to a base S and divided by partitions C to define a space with a rectangular section divided into four identical or different compartments intended to each contain a industrial equipment E. Each of these compartments is considered to form a barrier for the equipment it contains. Here we see walls 1, 2 having the same height. The four vertical walls 1,2,3,4 are made of reinforced concrete or other suitable material and have a height H of at least 2.4m. In the section, we see the walls 1, 2 defining the length of space, the walls 3,4 defining the width 2W. The ratio between width and length can have any value.

Entre les deux parois 1, 2 se dresse une cloison verticale C de même longueur que les parois 1, 2 mais plus haute que celles-ci. Ainsi dans la figure, on voit deux des compartiments, un pour l'équipement E et un pour l'équipement E1. Une personne peut opérer sur l'équipement, ici E1, en agissant sur des liens passant à travers la paroi, ici paroi 2.Between the two walls 1, 2 stands a vertical partition C of the same length as the walls 1, 2 but higher than them. So in the figure, we see two of the compartments, one for equipment E and one for equipment E1. A person can operate on the equipment, here E1, by acting on links passing through the wall, here wall 2.

Chacun des compartiments a une largueur W et une longueur égale à la moitié de la longueur des parois 1,2.Each of the compartments has a width W and a length equal to half the length of the walls 1.2.

L'espace parallélépipédique entre les parois 1,2,3,4 et le socle est partiellement fermé sur le dessus par quatre toits partiels T1, T2, T3, T4. Le toits partiel T1 est fixé à trois des parois verticales 1,3,4. Le toit T1 est une plaque, en béton armé ou autre matériel adapté et a une surface rectangulaire parallèle au socle S et perpendiculaire aux parois1,2,3,4, la surface du toit partiel T1 correspondant à la section rectangulaire de l'espace formé par les quatre parois 1,2,3,4. La largeur de la plaque du toit T1 est WT et sa longueur est celle des parois 1, 2. Ce toit partiel se trouve au-dessus de l'équipement E laissant un espace ouvert de largeur WA et de longueur égale celle des parois 1, 2.The parallelepiped space between the walls 1,2,3,4 and the base is partially closed on top by four partial roofs T1, T2, T3, T4. The partial roof T1 is attached to three of the vertical walls 1,3,4. The roof T1 is a plate, made of reinforced concrete or other suitable material and has a rectangular surface parallel to the base S and perpendicular to the walls1,2,3,4, the surface of the partial roof T1 corresponding to the rectangular section of the space formed by the four walls 1,2,3,4. The width of the roof plate T1 is W T and its length is that of the walls 1, 2. This partial roof is located above the equipment E leaving an open space of width W A and of length equal to that of the walls 1, 2.

W1 est égal au plus à 50% de W et WA est égal au moins à 50% de W.W 1 is equal to at most 50% of W and W A is equal to at least 50% of W.

Le toit T1 est une plaque, en béton armé ou autre matériel adapté et a une surface rectangulaire parallèle au socle S et perpendiculaire aux parois 1,2,3,4, la surface du toit partiel T1 correspondant au plus le quart de la section rectangulaire de l'espace formé par les quatre parois 1,2,3,4. La largeur de la plaque du toit T1 est WT et sa longueur est celle des parois 1, 2. Ce toit partiel se trouve au-dessus de l'équipement E laissant un espace ouvert de largeur WA et de longueur égale celle des parois 1, 2, traversant entièrement deux compartiments.The roof T1 is a plate, made of reinforced concrete or other suitable material and has a rectangular surface parallel to the base S and perpendicular to the walls 1,2,3,4, the surface of the partial roof T1 corresponding to at most a quarter of the rectangular section of the space formed by the four walls 1,2,3,4. The width of the roof plate T1 is W T and its length is that of the walls 1, 2. This partial roof is located above the equipment E leaving an open space of width W A and of length equal to that of the walls 1, 2, crossing two compartments entirely.

W1 est égal au plus à 50% de W et WA est égal au moins à 50% de W.W 1 is equal to at most 50% of W and W A is equal to at least 50% of W.

Le toit T2 est une plaque, en béton armé ou autre matériel adapté et a une surface rectangulaire parallèle au socle S et perpendiculaire aux parois 1,2,3,4 et la cloison C, la surface du toit partiel T2 correspondant au plus le quart de la section rectangulaire de l'espace formé par les quatre parois 1,2,3,4 et au plus la moitié de la section rectangulaire du compartiment formé par les cloisons et deux des parois. La largeur de la plaque du toit T2 est WT2 et sa longueur est celle des parois 1, 2. Le toit partiel T2 est fixé en haut de la cloison C parallèle au parois 1, 2. Ce toit partiel T2 ne se pas trouve au-dessus de l'équipement E.The roof T2 is a plate, made of reinforced concrete or other suitable material and has a rectangular surface parallel to the base S and perpendicular to the walls 1,2,3,4 and the partition C, the surface of the partial roof T2 corresponding to at most a quarter of the rectangular section of the space formed by the four walls 1,2,3,4 and at most half of the rectangular section of the compartment formed by the partitions and two of the walls. The width of the roof plate T2 is W T2 and its length is that of the walls 1, 2. The partial roof T2 is fixed at the top of the partition C parallel to the walls 1, 2. This partial roof T2 is not located at above equipment E.

W1 est égal au plus à 50% de W et WA est égal au moins à 50% de W.W 1 is equal to at most 50% of W and W A is equal to at least 50% of W.

Le positionnement décalé des toits partiels T2, T1 force l'air à s'engouffrer dans la barrière descendant le long de la cloison et circulant autour de l'équipement E, ainsi améliorant la ventilation de l'équipement E.The offset positioning of the partial roofs T2, T1 forces the air to rush into the barrier descending along the partition and circulating around the equipment E, thus improving the ventilation of the equipment E.

En miroir, de l'autre côté de la cloison, un toit partiel T3 est fixé au-dessus du compartiment où est disposé l'équipement E1. Un toit partiel T4 s'étend depuis le haut de la paroi 2 au-dessus de l'équipement E1.Mirrored, on the other side of the partition, a partial roof T3 is fixed above the compartment where the E1 equipment is located. A partial roof T4 extends from the top of wall 2 above equipment E1.

Comme indiqué la présence les toit partiels T2, T3 à plus grande hauteur peut permettre de réduire la taille des toits partiels T1, T4. Ici les toits partiels T1, T4 sont plus longs que les toits partiels T2, T3.As indicated, the presence of the partial roofs T2, T3 at greater height can make it possible to reduce the size of the partial roofs T1, T4. Here the partial roofs T1, T4 are longer than the partial roofs T2, T3.

Pour ce cas où les deux toits T1, T2 et T3, T4 forment des chicanes, il est important que les deux toits partiels ne se recouvrent pas pour laisser suffisamment de passage à l'air.For this case where the two roofs T1, T2 and T3, T4 form baffles, it is important that the two partial roofs do not overlap to allow sufficient passage for air.

Par exemple, la séparation verticale F entre deux toits recouvrant une partie d'une même espace est entre 20cm et 2m. La séparation horizontale D entre les extrémités libres des deux toits correspond à entre 25 et 75% de la largeur W.For example, the vertical separation F between two roofs covering part of the same space is between 20cm and 2m. The horizontal separation D between the free ends of the two roofs corresponds to between 25 and 75% of the width W.

Le toit T1 est fixé à la paroi 1 et optionnellement aux parois 3,4 et/ou aux cloisons C, C' si présentes mais pas à la paroi 2. Les toits T2 et T3 sont fixés uniquement à la cloison C. Le toit T4 est fixé à la paroi 2 et optionnellement aux parois 3,4 et/ou aux cloisons C, C'.Roof T1 is attached to wall 1 and optionally to walls 3,4 and/or partitions C, C' if present but not to wall 2. Roofs T2 and T3 are attached only to partition C. Roof T4 is fixed to wall 2 and optionally to walls 3,4 and/or partitions C, C'.

Selon une version simplifiée la cloison C peut simplement être plus haute que les parois 1, 2 et ne pas avoir de toit partiel, le simple effet de saillie pouvant améliorer la ventilation.According to a simplified version, partition C can simply be higher than walls 1, 2 and not have a partial roof, the simple projection effect being able to improve ventilation.

[Fig.5] montre que la présence du toit T3 de la [fig.4] n'est pas essentielle.[ Fig.5 ] shows that the presence of the T3 roof of the [ fig.4 ] is not essential.

Le toit T1 est fixé à la paroi 1 et optionnellement aux parois 3,4 ou aux cloisons C, C4 si présentes mais pas à la paroi 2. Le toit T2 est fixé uniquement à la cloison C.Roof T1 is attached to wall 1 and optionally to walls 3,4 or partitions C, C4 if present but not to wall 2. Roof T2 is attached only to partition C.

[Fig.6] montre que la présence du toit T2 de la [fig.4] n'est pas essentielle. Le toit T1 est fixé à la paroi 1 et optionnellement aux parois 3,4 ou aux cloisons C, C4 si présentes mais pas à la paroi 2. Le toit T3 est fixé uniquement à la cloison C.[ Fig.6 ] shows that the presence of the T2 roof of the [ fig.4 ] is not essential. Roof T1 is attached to wall 1 and optionally to walls 3,4 or partitions C, C4 if present but not to wall 2. Roof T3 is attached only to partition C.

[Fig.7] montre une vue de dessus de la barrière de la [Fig.4] avec ses quatre compartiments identiques et les deux cloisons C, C' perpendiculaires l'une à l'autre. La cloison C est parallèle au parois 1, 2 et perpendiculaire aux parois 3, 4 et la cloison C' est perpendiculaire au parois 1, 2 et parallèle aux parois 3, 4.[ Fig.7 ] shows a top view of the barrier of the [ Fig.4 ] with its four identical compartments and the two partitions C, C' perpendicular to each other. Partition C is parallel to walls 1, 2 and perpendicular to walls 3, 4 and partition C' is perpendicular to walls 1, 2 and parallel to walls 3, 4.

La barrière comprend quatre parois verticales 1,2,3,4 formant quatre côtés d'un parallélépipède fixées à un socle S pour définir un espace à section rectangulaire destiné à contenir les équipements industriels E, E1, E2, E3 disposés sur le socle. La longueur de cet espace est définie par les parois parallèles 1, 2 et le largueur de cet espace est définie par les parois parallèles 3, 4.The barrier comprises four vertical walls 1,2,3,4 forming four sides of a parallelepiped fixed to a base S to define a space with a rectangular section intended to contain industrial equipment E, E1, E2, E3 placed on the base. The length of this space is defined by the parallel walls 1, 2 and the width of this space is defined by the parallel walls 3, 4.

L'espace parallélépipédique entre les parois 1,2,3,4 et le socle est partiellement fermé sur le dessus par un toit partiel T1 fixé à trois des parois verticales 1,3,4. Le toit T1 est une plaque, en béton armé ou autre matériel adapté et a une surface rectangulaire parallèle au socle S et perpendiculaire aux parois1,2,3,4 des parois 1, 2.The parallelepiped space between the walls 1,2,3,4 and the base is partially closed on top by a partial roof T1 fixed to three of the vertical walls 1,3,4. The roof T1 is a plate, made of reinforced concrete or other suitable material and has a rectangular surface parallel to the base S and perpendicular to the walls 1,2,3,4 of the walls 1, 2.

Ici seule une partie de chaque équipement E1, E2, E se trouve directement en dessous du toit partiel T4, T1. L'équipement E4 est ici une conduite qui se trouve entièrement en dessous du toit partiel T4.Here only part of each equipment E1, E2, E is located directly below the partial roof T4, T1. The E4 equipment here is a pipe which is located entirely below the T4 partial roof.

[Fig. 8] montre une variante de l'invention où la barrière n'a pas de cloison C mais comprend quatre parois verticales 1,2,3,4 formant quatre côtés d'un parallélépipède fixées à un socle S pour définir un espace à section rectangulaire destiné à contenir l'équipement industriel E disposé sur le socle. Ici on voit les parois 1, 2 n'ont pas la même hauteur, la paroi 1 étant moins haute que la paroi 2. Les parois 1 et 3 ont de préférence la même hauteur. La paroi 4 formerait le fond de la coupe mais n'est pas illustrée. Les quatre parois verticales 1,2,3,4 sont en béton armé ou autre matériel adapté et ont une hauteur d'au moins 2, 4m. Les parois 1, 2 définissent la longueur de l'espace, les parois 3,4 en définissant la largeur W.[ Fig. 8 ] shows a variant of the invention where the barrier has no partition C but comprises four vertical walls 1,2,3,4 forming four sides of a parallelepiped fixed to a base S to define a space with a rectangular section intended to contain the industrial equipment E placed on the base. Here we see the walls 1, 2 do not have the same height, the wall 1 being lower than the wall 2. The walls 1 and 3 preferably have the same height. Wall 4 would form the bottom of the cup but is not illustrated. The four vertical walls 1,2,3,4 are made of reinforced concrete or other suitable material and have a height of at least 2.4m. Walls 1, 2 define the length of the space, walls 3,4 defining the width W.

L'équipement E se trouve au moins partiellement en dessous du toit T1 s'étendant depuis le haut de la paroi 1. L'équipement 3 n'est pas en dessous du toit T4 s'étendant depuis le haut de la paroi 2, le toit T4 étant à une élévation plus haute que celle du toit T1. Ainsi comme avant les toits T1, T4 forment des chicanes favorisant la ventilation autour de l'équipement.The equipment E is located at least partially below the roof T1 extending from the top of the wall 1. The equipment 3 is not below the roof T4 extending from the top of the wall 2, the roof T4 being at a higher elevation than that of roof T1. So, as before, the T1 and T4 roofs form baffles promoting ventilation around the equipment.

Le toit T1 est fixé à la paroi 1 et optionnellement aux parois 3,4 mais pas à la paroi 2. Le toit T4 est fixé uniquement à la paroi 2.Roof T1 is attached to wall 1 and optionally to walls 3,4 but not to wall 2. Roof T4 is attached only to wall 2.

Selon une version simplifiée la paroi 2 peut simplement être plus haute que la paroi 1 et ne pas avoir de toit partiel, le simple effet de saillie pouvant améliorer la ventilation.According to a simplified version, wall 2 can simply be higher than wall 1 and not have a partial roof, the simple projection effect being able to improve ventilation.
