Description

Mur végétal avec circulation interne d'air  Vegetal wall with internal air circulation
La présente invention concerne, d'une manière générale, le domaine technique des murs végétaux. Elle se rapporte, plus précisément, à un mur végétal avec circulation interne d'air. The present invention relates, in a general manner, to the technical field of plant walls. It relates, more specifically, to a plant wall with internal air circulation.
On connaît des structures de murs végétaux qui sont composées de casiers de forme générale prismatique, pouvant être juxtaposés et/ou superposés. Chaque casier d'une telle structure possède un châssis, qui supporte des faces grillagées ou maillées, notamment des faces avant et arrière grillagées ou maillées. Les casiers sont remplis d'un substrat de plantation, tel que terreau qui, en cas de configuration ajourée des faces par lesquelles ces casiers sont rendus adjacents, peut s'étendre sans discontinuité à l'intérieur de la structure du mur végétal. A titre d'exemples, on peut citer le brevet français FR 2872381 et son équivalent le brevet européen EP 1771062, au nom du demandeur.  There are known plant wall structures that are composed of generally prismatic lockers, which can be juxtaposed and / or superimposed. Each rack of such a structure has a frame, which supports meshed or meshed faces, in particular meshed and meshed front and rear faces. The bins are filled with a planting substrate, such as potting soil which, in the case of a perforated configuration of the faces through which these bins are made adjacent, can extend without interruption within the structure of the plant wall. By way of examples, mention may be made of French patent FR 2872381 and its equivalent European patent EP 1771062, in the name of the applicant.
Dans les réalisations décrites par ces documents, il est prévu un réseau de conduits d'eau et aussi un réseau de tubes d'air, qui s'étendent dans l'épaisseur des différents casiers juxtaposés et/ou superposés, donc à l'intérieur du substrat de plantation remplissant ces casiers, en traversant les plans de joint horizontaux et/ou verticaux entre casiers adjacents. Les faces inférieures, supérieures et latérales des casiers étant ajourées, celles-ci permettent le libre passage des réseaux d'air et d'eau, d'un casier vers un casier adjacent, sans nécessité de perçage ou d'installation de raccords spéciaux, ce qui facilite la fabrication et la mise en place de la structure du mur végétal.  In the embodiments described by these documents, there is provided a network of water pipes and also a network of air tubes, which extend in the thickness of the different juxtaposed and / or superimposed bins, so inside planting substrate filling these trays, crossing the horizontal and / or vertical joint planes between adjacent traps. The lower, upper and lateral faces of the bins being perforated, they allow the free passage of the air and water networks, from a locker to an adjacent rack, without the need for drilling or installation of special fittings, which facilitates the manufacture and implementation of the structure of the plant wall.
Le réseau d'air permet de faire circuler de l'air pollué extérieur ou intérieur, puisé par une pompe, pour dépolluer cet air au contact du substrat de plantation, par un effet de filtration auquel s'ajoute une action bactérienne selon le principe du biofiltre. L'obtention d'un tel fonctionnement suppose toutefois que l 'air à dépolluer soit d iffusé de façon optimale dans le substrat de plantation. De plus, pour conserver un bilan énergétique avantageux, la d iffusion de l'air dans le substrat doit se faire avec une consommation d'énergie minimale.  The air network makes it possible to circulate polluted external or internal air, pulsed by a pump, to depollute this air in contact with the planting substrate, by a filtration effect to which is added a bacterial action according to the principle of biofilter. Obtaining such an operation assumes, however, that the air to be decontaminated is optimally removed in the planting substrate. In addition, in order to maintain an advantageous energy balance, the air must be diffused into the substrate with minimal energy consumption.
Dans les réalisations actuelles, la diffusion de l'air dans le substrat de plantation est obtenue par des perforations prévues dans les tubes d'air. Cette solution, certes simple, ne procure pas une bonne répartition de l'air dans l'ensemble d'un casier. Ainsi, une partie du substrat se trouve saturée en air pollué, tandis que le volume du casier conserve des zones dans lesquelles l'air ne parvient pratiquement pas. La mauvaise répartition de l'air conduit à une inefficacité de la fonction de dépollution de cet air. In current embodiments, the diffusion of air into the planting substrate is obtained by perforations provided in the air tubes. This solution, certainly simple, does not provide a good distribution of air in the whole of a locker. Thus, a portion of the substrate is saturated with polluted air, while the volume of the trap keeps areas in which the air hardly reaches. The bad distribution of the air leads to an inefficiency of the function of depollution of this air.
Par ailleurs, la distribution de l'air puisé au travers de perforations ménagées dans les tubes d'air nécessite une puissance relativement élevée, donc une pompe volumineuse et très consommatrice d'énergie, délivrant une pression élevée qui n'optimise pas le temps de séjour de l'air dans le substrat. L'augmentation de la section de passage des perforations n'est pas une solution adaptée, car elle entraîne un risque de pénétration du substrat dans le réseau d'air, avec comme conséquence un risque de colmatage des tubes d'air donc un résultat qui serait le contraire de ce que l'on souhaite.  Furthermore, the distribution of air pulsed through perforations in the air tubes requires a relatively high power, so a large pump and very energy-consuming, delivering a high pressure that does not optimize the time of stay of the air in the substrate. The increase in the passage section of the perforations is not a suitable solution, because it entails a risk of penetration of the substrate into the air network, with the consequence of a risk of clogging of the air tubes, therefore a result which would be the opposite of what we want.
La présente invention vise à remédier aux inconvénients précédemment exposés, et elle a donc pour but de fournir, pour un mur végétal du genre ici considéré, un système de diffusion interne de l'air qui soit plus performant, en particulier un système répartissant l'air de façon homogène dans les casiers, donc dans le substrat de plantation, de manière à améliorer la dépollution de cet air, tout en augmentant le rendement énergétique.  The present invention aims to remedy the disadvantages previously described, and is therefore intended to provide, for a plant wall of the kind considered here, an internal air diffusion system that is more efficient, particularly a system spreading the air homogeneously in the bins, so in the planting substrate, so as to improve the depollution of this air, while increasing the energy efficiency.
A cet effet, l'invention a pour objet un mur végétal avec circulation interne d'air, le mur végétal comprenant une structure composée de casiers de forme générale prismatique, prévus pour être juxtaposés et/ou superposés, chaque casier possédant un châssis qui supporte des faces grillagées ou maillées avec notamment une face avant grillagée ou maillée, les casiers étant prévus pour être remplis d'un substrat de plantation pour des végétaux se développant au moins sur la face avant de ces casiers, le mur végétal comprenant un réseau de distribution d'air relié à des moyens de pompage d'air et amenant de l'air dans l'épaisseur des différents casiers juxtaposés et/ou superposés, donc à l'intérieur du substrat de plantation, pour une action dépolluante, ce mur végétal étant caractérisé par le fait que le réseau de distribution d'air comprend, disposé verticalement à l'intérieur de chaque casier, au moins un plénum de distribution d'air raccordé à un conduit d'amenée d'air puisé, le plénum comportant, sur l'une au moins de ses deux faces principales, une fenêtre ou grille de diffusion d'air.  To this end, the subject of the invention is a plant wall with internal air circulation, the plant wall comprising a structure composed of generally prismatic bins, intended to be juxtaposed and / or superimposed, each rack having a frame that supports meshed or meshed faces, in particular with a grid or meshed front face, the bins being designed to be filled with a planting substrate for plants developing at least on the front face of these bins, the plant wall comprising a distribution network air connected to means for pumping air and bringing air into the thickness of the different juxtaposed and / or superimposed bins, therefore inside the planting substrate, for a depolluting action, this plant wall being characterized in that the air distribution network comprises, arranged vertically inside each bin, at least one connected air distribution plenum to a pulsed air supply duct, the plenum comprising, on at least one of its two main faces, a window or air diffusion grille.
Ainsi, l'invention prévoit de remplacer les tubes perforés de d istribution d'air par un plénum, lequel permet une diffusion répartie et homogène de l'air dans chaque casier du mur végétal, donc dans le substrat de plantation remplissant ce casier. La distribution de l'air au travers d'une fenêtre ou grille de section importante permet, en outre, une diffusion relativement lente de cet air, optimisant le temps de séjour de l'air dans le substrat pour une action dépolluante plus efficace, tout en procurant une économie de consommation d'énergie nécessaire au fonctionnement de la pompe. La fenêtre ou grille de diffusion d'air peut comporter une membrane poreuse au travers de laquelle l'air est diffusé vers le substrat de plantation, ce qui ralentit encore la circulation de l'air tout en empêchant l'entrée indésirable du substrat à l'intérieur du plénum. Thus, the invention provides for the replacement of the perforated air distribution tubes with a plenum, which allows a distributed and homogeneous distribution of the air in each cell of the green wall, and therefore in the substrate. plantation filling this trap. The distribution of air through a window or grid of large section also allows a relatively slow diffusion of this air, optimizing the residence time of the air in the substrate for a more effective depolluting action, while by providing a saving of energy consumption necessary for the operation of the pump. The air diffusion window or grid may include a porous membrane through which air is diffused to the planting substrate, further slowing the flow of air while preventing undesirable entry of the substrate to the substrate. inside the plenum.
Avantageusement, chaque plénum de distribution d'air, associé à un casier, est fixé verticalement au châssis du casier, ce qui assure son positionnement précis et son maintien en place, même en l'absence de substrat. La grille de diffusion d'air contribue à la rigidité du plénum et de l'ensemble.  Advantageously, each air distribution plenum, associated with a rack, is fixed vertically to the frame of the rack, which ensures its precise positioning and its retention in place, even in the absence of substrate. The air diffusion grid contributes to the rigidity of the plenum and the assembly.
Dans le cas d'un mur végétal avec plantation de végétaux sur la seule face avant des casiers, chaque plénum de distribution d'air est avantageusement disposé verticalement sur la face arrière du casier correspondant, le plénum comportant lui-même une face arrière pleine et une face avant avec fenêtre ou grille de diffusion d'air.  In the case of a plant wall with planting plants on the single front of the bins, each air distribution plenum is advantageously arranged vertically on the rear face of the corresponding bin, the plenum itself having a full back face and a front face with window or air diffusion grid.
Dans le cas d'un mur végétal avec plantation de végétaux sur la face avant et aussi sur la face arrière des casiers, chaque plénum de distribution d'air pourra, au contraire, être disposé verticalement à mi-épaisseur du casier correspondant, donc à égale distance des faces avant et arrière du casier, le plénum lui-même comportant une face avant avec fenêtre ou grille de diffusion d'air , et une face arrière également avec fenêtre ou grille de distribution d'air.  In the case of a plant wall with planting plants on the front face and also on the rear face of the bins, each air distribution plenum may, on the contrary, be arranged vertically at mid-thickness of the corresponding rack, so equal distance of the front and rear of the bin, the plenum itself having a front face with window or air diffusion grid, and a rear face also with window or air distribution grid.
Dans un mode de réalisation de l'invention, la seule face avant ou les faces avant et arrière du plénum de distribution d'air, selon le cas, com portent autou r de l a fenêtre ou g rille de diffusion d'air une zone périphérique pleine. Cette zone peut être rigide ou plus ou moins souple.  In one embodiment of the invention, the only front face or the front and rear faces of the air distribution plenum, as the case may be, include a peripheral zone outside the air distribution window or garrel. full. This zone can be rigid or more or less flexible.
Dans la conception la plus simple, la zone périphérique pleine possède une largeur constante, sur tous les côtés de la fenêtre ou grille de diffusion d'air, de sorte que cette fenêtre ou grille possède une position centrée sur le plénum, donc aussi dans le casier.  In the simplest design, the solid peripheral zone has a constant width, on all sides of the window or air diffusion grid, so that this window or grid has a position centered on the plenum, therefore also in the locker.
Toutefois, pour tenir compte par anticipation du tassement du substrat de plantation à l'intérieur du casier, il peut être avantageux que la zone périphérique pleine possède, au-dessus de la fenêtre ou grille de diffusion d'air, une hauteur plus grande que sa hauteur au-dessous de la fenêtre ou grille de diffusion d'air. Ainsi, la fenêtre ou grille reste centrée par rapport au substrat, malgré le tassement de ce dernier. La diffusion homogène de l'air dans le substrat reste donc garantie dans le temps. However, to take account in advance of the settlement of the planting substrate inside the bin, it may be advantageous if the area Full device has, above the window or air diffusion grid, a height greater than its height below the window or air diffusion grid. Thus, the window or grid remains centered relative to the substrate, despite the settlement of the latter. The homogeneous diffusion of air in the substrate therefore remains guaranteed over time.
L'invention a aussi pour objet, en tant que tel, un plénum de distribution d'air pour mur végétal avec circulation interne d'air, le plénum se présentant comme un caisson plat, de contour carré ou rectangulaire, comportant à sa périphérie un raccord pour son raccordement à un conduit d'amenée d'air puisé, tandis que l'une au moins de ses deux faces principales comporte une fenêtre ou grille de diffusion d'air.  The invention also has as its object, as such, an air distribution plenum for a plant wall with internal air circulation, the plenum being a flat box of square or rectangular contour, comprising on its periphery a connection for its connection to a pulsed air supply duct, while at least one of its two main faces comprises an air diffusion window or grille.
L'invention sera mieux comprise à l'aide de la description qui suit, en référence au dessin schématique annexé représentant, à titre d'exemples, quelques formes d'exécution de ce plénum de distribution d'air et du mur végétal en faisant application :  The invention will be better understood from the description which follows, with reference to the appended schematic drawing showing, by way of example, some embodiments of this air distribution plenum and the plant wall by applying :

Les figures 1 à 6 montrent un casier 1 , de forme générale parallélépipédique, constitutif de la structure d'un mur végétal . Le casier 1 possède un châssis 2 formé de montants 3, de longerons 4 et de traverses 5, qui délimitent une face avant 6, une face arrière 7, une face supérieure 8, une face inférieure 9 et deux faces latérales 1 0. Les différentes faces 6 à 1 0 du casier 1 peuvent être des faces grillagées, c'est-à-dire qu'elles comportent un grillage ou un maillage formé par des fils métall iques. En particulier, la face avant 6 du casier 1 peut présenter un grillage formé par des fils métalliques horizontaux et par des fils métalliques verticaux entrecroisés. Cette face avant 6 du casier 1 peut comporter un cadre rectangulaire amovible, lequel supporte les fils métalliques horizontaux et verticaux formant le grillage.  Figures 1 to 6 show a rack 1, of parallelepiped general shape, constituting the structure of a plant wall. The rack 1 has a frame 2 formed of uprights 3, longitudinal members 4 and crosspieces 5, which delimit a front face 6, a rear face 7, an upper face 8, a lower face 9 and two lateral faces 1 0. The different 6 to 10 faces of the rack 1 may be grid faces, that is to say that they comprise a mesh or a mesh formed by metal son iques. In particular, the front face 6 of the rack 1 may have a grid formed by horizontal metal son and interwoven vertical son son. This front face 6 of the rack 1 may comprise a removable rectangular frame, which supports the horizontal and vertical wires forming the wire mesh.
Le casier 1 est juxtaposé et/ou superposé à des casiers similaires, pour constituer la structure complète d'un mur végétal . Tous les casiers 1 ainsi réunis sont remplis d'un substrat de plantation, sur lequel se développent des végétaux 1 1 qui apparaissent au moins sur la face avant 6 des casiers -voir figure 6.  Bin 1 is juxtaposed and / or superimposed on similar bins to form the complete structure of a plant wall. All the racks 1 thus joined are filled with a planting substrate, on which grow plants 1 1 which appear at least on the front face 6 of the racks - see Figure 6.
Le mur végétal comporte un réseau de distribution d'air 12, lequel comprend des tubes d'amenée d'air 1 3 et une pompe 14 puisant l'air. Les tubes d'amenée d'air 13 sont dirigés vers les différents casiers 1 , et ils aboutissent à des plénums 15 de distribution d'air, disposés à l'intérieur des casiers 1 .  The green wall comprises an air distribution network 12, which comprises air supply tubes 1 3 and a pump 14 drawing air. The air supply tubes 13 are directed towards the different compartments 1, and they end at air distribution plenums 15 arranged inside the compartments 1.
Chaque plénum 1 5 de distribution d'air se présente comme un caisson plat qu i possède un contour carré ou rectangulaire, avec une face avant 16 et une face arrière 17.  Each air distribution plenum 1 5 is in the form of a flat box which has a square or rectangular outline, with a front face 16 and a rear face 17.
La face avant 16 du plénum 15 comporte une grille 18 de diffusion d'air, de forme carrée ou rectangulaire. La grille 18 est entourée par une zone périphérique 1 9 pleine. La face arrière 1 7 d u plénu m 1 5 est ici u ne face entièrement pleine.  The front face 16 of the plenum 15 comprises a grid 18 of air diffusion, of square or rectangular shape. The gate 18 is surrounded by a full peripheral area 19. The rear face 17 of a plenum 15 is here a completely full face.
Le plénum 15 est monté verticalement dans le casier 1 , sur la face arrière 7 de ce casier, en étant fixé au châssis 2, de telle sorte que sa grille 18 de diffusion d'air soit tournée vers le substrat de plantation remplissant ce casier 1 . La périphérie du plénum 15, par exemple le bord supérieur de ce plénum, est reliée par un raccord 20 à un tube d'amenée d'air 13. The plenum 15 is mounted vertically in the rack 1, on the rear face 7 of this rack, being fixed to the frame 2, so that its grid 18 of air diffusion is turned towards the planting substrate filling this rack 1. The periphery of the plenum 15, for example the upper edge of this plenum, is connected by a connection 20 to an air supply tube 13.
En utilisation, de l'air puisé par la pompe 14 est envoyé par l'intermédiaire des tubes d'amenée d'air 13 jusqu'à l'intérieur de chaque plénum 15, qui diffuse cet air avec une répartition homogène, au travers de sa grille 18, vers l'intérieur du substrat de plantation. Le passage de l'air au travers de ce substrat assure une dépollution de l'air par un effet de biofiltre. La grille 18 de diffusion d'air peut comporter une membrane poreuse (non représentée) au travers de laquel le l'air est d iffusé vers le substrat de plantation , pour empêcher toute entrée indésirable du substrat à l'intérieur du plénum 15.  In use, air drawn by the pump 14 is sent via the air supply tubes 13 to the inside of each plenum 15, which diffuses this air with a homogeneous distribution, through its grid 18, towards the inside of the planting substrate. The passage of the air through this substrate ensures a depollution of the air by a biofilter effect. The air diffusion grid 18 may comprise a porous membrane (not shown) through which air is blown to the planting substrate to prevent undesired entry of the substrate into the plenum 15.
Comme le montre la figure 3, la zone périphérique 19 pleine de la face avant 1 6 du plénum 1 5 possède, dans sa bande supérieure c'est-à-dire située au-dessus de la grille 1 8, une hauteur H plus grande que sa hauteur h dans sa bande inférieure, c'est-à-dire située au-dessous de la grille 18. Ainsi, le tassement du substrat de plantation à l'intérieur du casier 1 est en pris en compte par anticipation, la grille 18 étant décentrée vers le bas.  As shown in FIG. 3, the full peripheral zone 19 of the front face 1 6 of the plenum 1 5 has, in its upper band, that is to say situated above the grid 1 8, a larger height H. that its height h in its lower band, that is to say below the grid 18. Thus, the settlement of the planting substrate inside the bin 1 is taken into account in anticipation, the grid 18 being off-center down.
Comme le montre le dessin , un panneau photovoltaïque 21 porté par la structure précédemment décrite peut fournir l'énergie électrique nécessaire au fonctionnement de la pompe 14 qui met en circulation l'air dans le réseau de distribution 12, comprenant les tubes d'amenée d'air 13 et les différents plénums 15.  As shown in the drawing, a photovoltaic panel 21 carried by the previously described structure can provide the electrical energy necessary for the operation of the pump 14 which circulates the air in the distribution network 12, comprising the supply tubes air 13 and the various plenums 15.
Les figures 7 à 12 montrent un autre mode de réalisation, adapté à un mur végétal dans lequel les végétaux 1 1 sont plantés et se développent aussi bien sur la face avant 6 que sur la face arrière 7 des différents casiers 1 .  Figures 7 to 12 show another embodiment, adapted to a plant wall in which the plants 1 1 are planted and develop both on the front face 6 than on the rear face 7 of the various lockers 1.
Dans ce cas, chaque plénum 15 de distribution d'air est disposé verticalement, et fixé au châssis 2, à mi-épaisseur du casier 1 , ce plénum 15 étant comme précédemment relié à un tube 13 d'amenée d'air, puisé par une pompe 14.  In this case, each plenum 15 of air distribution is arranged vertically, and fixed to the frame 2, mid-thickness of the rack 1, this plenum 15 being as previously connected to a tube 13 of air intake, drawn by a pump 14.
Le plénum 15 possède une première grille 18 sur sa face avant 16, et une seconde grille 18 analogue sur sa face arrière 17. L'air est ainsi diffusé, depuis le plénum 15, vers le substrat de plantation situé en avant de ce plénum et simultanément vers le substrat de plantation situé en arrière de ce plénum.  The plenum 15 has a first gate 18 on its front face 16, and a second gate 18 similar on its rear face 17. The air is thus diffused, from the plenum 15, to the planting substrate located in front of this plenum and simultaneously to the planting substrate located behind this plenum.
On ne s'éloignerait pas du cadre de l'invention, telle que définie dans les revendications annexées, en modifiant : - La matière constitutive du plénum de distribution d'air, laquelle peut être plus ou moins rigide ou au contraire souple, It would not depart from the scope of the invention, as defined in the appended claims, by modifying: - The constituent material of the air distribution plenum, which can be more or less rigid or flexible,
