BERCE POUR CAMION AVEC CUVE A DECHETS ORGANIQUES TRUCK FOR TRUCK WITH ORGANIC WASTE TANK
Domaine technique Technical area
[0001] L'invention a trait au domaine du stockage et du transport des déchets, plus particulièrement des déchets organiques, tels que les déchets ménagers ou alimentaires de la grande distribution et de restaurants ou de cantines de collectivités. The invention relates to the field of storage and transport of waste, particularly organic waste, such as household or food waste from large retailers and restaurants or community canteens.
Technique antérieure Prior art
[0002] Le document de brevet publié EP 1 905 703 A1 divulgue un véhicule, en l'occurrence un camion, spécialement équipé d'un dispositif de stockage et de transport de déchets organiques. Le camion comprend une cuve de stockage des déchets, ladite cuve étant généralement circulaire allongée disposée à l'horizontale. Le camion comprend également une goulotte de déversement équipée d'un broyeur et reliée au contenu de la cuve à déchets par une conduite. Les déchets organiques, du type déchets de cuisine, sont déposés dans la goulotte pour y être broyés par un broyeur et ensuite être aspirés vers la cuve par une dépression présente dans ladite cuve. Pour faire la dépression, une pompe à vide est reliée à l'enceinte de la cuve. Un réservoir d'eau est prévu entre le cabinet du camion et la cuve à déchets. Ce réservoir peut être chauffé. Cette eau est destinée au lavage de la cuve. Un réservoir auxiliaire pour récolter les huiles et graisses est prévu dans le réservoir à eau afin que ces huiles et graisses jouissent de la chaleur de l'eau et restent liquides et faciles à vidanger. [0002] The published patent document EP 1 905 703 A1 discloses a vehicle, in this case a truck, specially equipped with a device for storing and transporting organic waste. The truck comprises a waste storage tank, said tank being generally circular elongated disposed horizontally. The truck also includes a discharge chute equipped with a crusher and connected to the contents of the hopper by a pipe. The organic waste, of the kitchen waste type, is deposited in the chute to be ground by a mill and then sucked to the tank by a vacuum in said tank. To make the vacuum, a vacuum pump is connected to the enclosure of the tank. A water tank is provided between the truck cabinet and the waste tank. This tank can be heated. This water is intended for washing the tank. An auxiliary tank for collecting oils and greases is provided in the water tank so that these oils and greases enjoy the warmth of the water and remain liquid and easy to drain.
[0003] Le dispositif décrit ci-avant est intéressant en ce qu'il permet de collecter et de transporter des déchets organiques alimentaires. Le maintien de la cuve en dépression favorise le transfert de déchets depuis la goulotte de déversement. Cela permet également de limiter la vitesse de décomposition des déchets dans la cuve. Dans la pratique, un tel ralentissement n'est cependant pas particulièrement utile car le camion, s'il est utilisé de manière efficace à l'occasion d'une tournée de collecte, va se déplacer de place en place pour collecter les déchets sur un laps de
temps réduit, typiquement un ou plusieurs jours, jusqu'à ce qu'il soit plein. Or ces déchets ne se décomposent pas en quelques jours, même par forte chaleur. Une fois la cuve remplie, le camion peut ensuite aller vider son contenu à un centre de traitement de déchets organiques. La dépression qui est réalisée dans la cuve semble servir essentiellement au transfert des déchets depuis la goulotte vers la cuve. Les gaz contenus dans la cuve et potentiellement malodorants sont aspirés par la pompe à vide et sont expulsées directement à l'atmosphère. Cela ne pose pas nécessairement de problème dans la mesure où le camion se déplace en principe de point de collecte en point de collecte. La solution de cet enseignement est intéressante dans une logique de collecte. Elle manque cependant d'être adéquate pour le stockage des déchets. The device described above is interesting in that it allows to collect and transport food organic waste. Keeping the tank in a vacuum facilitates the transfer of waste from the discharge chute. This also makes it possible to limit the rate of decomposition of the waste in the tank. In practice, such a slowdown is however not particularly useful because the truck, if it is used efficiently during a round of collection, will move from place to place to collect the waste on a lapse of reduced time, typically one or more days, until it is full. However, this waste does not decompose in a few days, even in strong heat. Once the tank is full, the truck can then empty its contents to an organic waste treatment center. The depression that is carried out in the tank seems to be used mainly for the transfer of waste from the chute to the tank. The gases contained in the tank and potentially smelly are sucked by the vacuum pump and are expelled directly to the atmosphere. This is not necessarily a problem since the truck usually moves from a collection point to a collection point. The solution of this teaching is interesting in a logic of collection. However, it is not adequate for storing waste.
[0004] Le document de brevet publié WO 2014/059478 A1 divulgue un dispositif mobile de récupération et de traitement de déchets organiques du type alimentaire. Ce dispositif est monté sur un véhicule et comprend une goulotte de déversement des déchets, et un broyeur pourvu d'une alimentation en eau. L'eau chargée en déchets broyés est ensuite transférée vers un réservoir. Ce dispositif présente l'avantage de neutraliser les odeurs des déchets par leur traitement et incorporation dans de l'eau. Il présente également l'avantage que l'eau peut être utilisée, préalablement au mélange avec les déchets, pour nettoyer les conteneurs à déchets déversés dans la goulotte du dispositif. Il présente toutefois l'inconvénient qu'il requiert le stockage et le transport d'une grande quantité d'eau. De plus, les déchets sont sous forme de boue, ce qui n'est pas particulièrement adéquat pour leur valorisation notamment pour de la méthanisation et du compostage en fonction du taux de siccité. The published patent document WO 2014/059478 A1 discloses a mobile device for the recovery and treatment of organic waste of the food type. This device is mounted on a vehicle and includes a chute for dumping waste, and a mill provided with a water supply. The water loaded with crushed waste is then transferred to a reservoir. This device has the advantage of neutralizing the odors of waste by their treatment and incorporation into water. It also has the advantage that the water can be used, prior to mixing with the waste, to clean the waste containers dumped in the chute of the device. However, it has the disadvantage that it requires the storage and transport of a large amount of water. In addition, the waste is in the form of sludge, which is not particularly suitable for their recovery, particularly for methanation and composting as a function of the rate of dryness.
[0005] Le document de brevet publié DE 203 17 332 U1 divulgue un dispositif de stockage et de transport de déchets organiques du type feuilles mortes. Le dispositif comprend, essentiellement, un conteneur fermé divisé en deux chambres, à savoir une chambre principale destinée au stockage des déchets et une chambre auxiliaire logeant un aspirateur dont la sortie est reliée à la chambre principale en vue d'y introduire les déches aspirés aux
alentours du conteneur au moyen d'un tuyau flexible raccordé audit aspirateur. The published patent document DE 203 17 332 U1 discloses a device for storing and transporting organic waste of the dead leaf type. The device comprises, essentially, a closed container divided into two chambers, namely a main chamber for the storage of waste and an auxiliary chamber housing a vacuum cleaner whose output is connected to the main chamber to introduce the dust sucked to around the container by means of a hose connected to said vacuum cleaner.

Description d'un mode de réalisation
[0032] La figure 1 illustre un dispositif de stockage et/ou de transport de déchets organiques, tels que des déchets alimentaires. Le dispositif 2 comprend un plateau 4 avec une portion principale 41 généralement horizontale et destinée à recevoir les différents composants du dispositif, et une portion avant généralement verticale et équipée d'un moyen d'accrochage, tel qu'un anneau ou orifice 43, avec un crochet d'un bras mécanique d'un camion berce en vue du déchargement et chargement du dispositif. Description of an embodiment [0032] Figure 1 illustrates a storage device and / or transport of organic waste, such as food waste. The device 2 comprises a plate 4 with a main portion 4 1 generally horizontal and intended to receive the various components of the device, and a front portion generally vertical and equipped with a hooking means, such as a ring or orifice 4 3 , with a hook of a mechanical arm of a truck rocks for unloading and loading the device.
[0033] Le dispositif 2 comprend également une cuve 6 destinée à recevoir les déchets. La cuve 6 comprend une enveloppe principale 61, en l'occurrence généralement cylindrique et horizontale. Il est toutefois entendu que la cuve peut présenter d'autres formes. La cuve 6 comprend également un couvercle à son extrémité arrière. Ce dernier est monté pivotant par des moyens de pivotement et de commande du pivotement 63. Il peut s'agit d'une charnière et d'un vérin hydraulique, bien connus en soi de l'homme de métier. Le couvercle 62 et l'enveloppe principale 61 de la cuve peuvent comprendre des moyens de fermeture et de mise en pression 64 du couvercle contre l'enveloppe, afin de former une enceinte étanche. La cuve 6 peut également comprendre à son sommet une trappe d'accès 65 pourvue également de moyens de fermeture et d'étanchéité. Une vanne (non représentée) peut également être prévue pour la mise à l'atmosphère de l'enceinte de la cuve. La cuve 6 peut également comprendre une ou plusieurs fenêtres 66 disposées verticalement, destinées à permettre de visualiser le niveau de remplissage de la cuve. The device 2 also comprises a tank 6 for receiving the waste. The tank 6 comprises a main envelope 6 1 , in this case generally cylindrical and horizontal. However, it is understood that the tank may have other forms. The tank 6 also comprises a cover at its rear end. The latter is pivotally mounted by means of pivoting and controlling the pivoting 6 3 . It may be a hinge and a hydraulic cylinder, well known to those skilled in the art. The lid 6 2 and the main envelope 6 1 of the tank may comprise means for closing and setting pressure 6 4 of the lid against the casing to form a sealed enclosure. The tank 6 can also comprise at its top an access door 6 5 also provided with closure means and sealing. A valve (not shown) may also be provided for venting the chamber of the vessel. The tank 6 may also include one or more windows 6 6 arranged vertically, to allow to visualize the level of filling of the tank.
[0034] Le dispositif 2 comprend également une goulotte de déversement des déchets 8. Celle-ci comprend une goulotte 81 en tant que telle, optionnellement équipée en sa partie inférieure d'un broyeur 82. La goulotte 81 est surmontée d'un couvercle 83 mobile, préférentiel lement pivotant, entre une position ouverte et une position fermée. La goulotte de déversement est reliée, d'un point de vue fluidique, à l'enceinte de la cuve à déchets 6 via la conduite 10. Une électrovanne 12 est disposée, d'un point de vue fluidique, le long de la conduite en question. La conduite 10 débouche à un point haut 14 de la paroi de la cuve 6. De manière alternative, éventuellement de manière sélective, ou encore de manière
complémentaire, la conduite 10 peut également déboucher à un point bas 14' de la paroi de la cuve 6. L'intérêt de cette mesure sera détaillé en relation avec la figure 3. The device 2 also comprises a waste discharge chute 8. This comprises a trough 8 1 as such, optionally equipped in its lower part with a mill 8 2 . The chute 8 1 is surmounted by a movable lid 8 3 , preferably pivotal, between an open position and a closed position. The discharge chute is connected, from a fluidic point of view, to the enclosure of the waste tank 6 via the pipe 10. A solenoid valve 12 is arranged, from a fluid point of view, along the pipe. question. The pipe 10 opens at a high point 14 of the wall of the tank 6. Alternatively, optionally selectively, or so complementary, the pipe 10 can also lead to a low point 14 'of the wall of the tank 6. The interest of this measure will be detailed in connection with Figure 3.
[0035] Toujours en référence à la figure 1 , le dispositif 2 comprend également une pompe à vide 16 raccordée, d'un point de vue fluidique, avec l'enceinte de la cuve 6 via un conduite 18. Un clapet anti-retour (non représenté) peut être prévu dans la conduite 18, notamment au niveau de la paroi de la cuve et/ou au niveau de la pompe 18. Still with reference to Figure 1, the device 2 also comprises a vacuum pump 16 connected, from a fluid point of view, with the chamber of the vessel 6 via a pipe 18. A non-return valve ( not shown) can be provided in the pipe 18, in particular at the wall of the tank and / or at the pump 18.
[0036] La sortie de la pompe 16 est raccordée, d'un point de vue fluidique, avec une unité de neutralisation des odeurs 20. Les gaz contenus dans l'enceinte de la cuve peuvent contenir divers types de molécules comme notamment du sulfure d'hydrogène ou du mercaptan (composé organique comportant un groupement thiol -SH, c'est-à-dire un groupement sulfhydryle attaché à un atome de carbone) qui sont particulièrement malodorants. La sortie de la pompe à vide 16 est donc susceptible de produire un débit de gaz malodorant particulièrement gênant pour une utilisation stationnaire. Pour pallier ce problème, la sortie de la pompe à vide est raccordée, toujours d'un point de vue fluidique, avec l'unité de neutralisation des odeurs. Celle-ci peut fonctionner sur le principe d'adsorption, consistant à transférer le composé à éliminer de la phase gazeuse vers une phase solide. Le matériau le plus couramment utilisé est le charbon actif qui se présente sous différentes formes: grains, tissus... etc. Afin d'accroître les performances, le charbon est parfois imprégné d'aldéhyde notamment. Alternativement ou de manière complémentaire, on peut procéder à un lavage des gaz, c'est-à-dire qu'on procède au lavage du flux gazeux par une solution aqueuse par transfert des composés à éliminer de la phase gazeuse vers la phase liquide. Cette technique s'accompagne souvent d'une réaction chimique. Si le composé transféré ne subit aucune modification, seule l'absorption physique intervient. Si en phase liquide, pour améliorer la "solubilité apparente" du produit à éliminer, on joue sur le pH pour favoriser sa dissociation, le procédé est un transfert de masse accompagné d'une réaction chimique
instantanée. L'unité de neutralisation des odeurs par lavage sera détaillée en relation avec la figure 2. The output of the pump 16 is connected, from a fluidic point of view, with a unit for neutralizing odors 20. The gases contained in the chamber of the vessel may contain various types of molecules such as, for example, sulphide. hydrogen or mercaptan (organic compound having a thiol group -SH, that is to say a sulfhydryl group attached to a carbon atom) which are particularly malodorous. The output of the vacuum pump 16 is therefore likely to produce a malodorous gas flow particularly troublesome for stationary use. To overcome this problem, the outlet of the vacuum pump is connected, still from a fluid point of view, with the odor neutralization unit. This can operate on the principle of adsorption, consisting in transferring the compound to be removed from the gas phase to a solid phase. The most commonly used material is activated charcoal which comes in different forms: grains, fabrics ... etc. In order to increase the performance, the coal is sometimes impregnated with aldehyde in particular. Alternatively or in a complementary manner, it is possible to carry out a washing of the gases, that is to say that the gas stream is washed with an aqueous solution by transfer of the compounds to be removed from the gas phase to the liquid phase. This technique is often accompanied by a chemical reaction. If the transferred compound undergoes no modification, only physical absorption occurs. If in the liquid phase, to improve the "apparent solubility" of the product to be eliminated, the pH is used to promote its dissociation, the process is a mass transfer accompanied by a chemical reaction Instant. The odor neutralization unit by washing will be detailed in relation to FIG. 2.
[0037] Le dispositif 2 peut comprendre un système de préhension, de levage et de basculement (non représenté) de conteneurs des déchets vers la goulotte 81 en tant que telle. Un tel système peut être animé par des vérins hydrauliques et/ou pneumatiques. Il est destiné à faciliter la manipulation des conteneurs, en particulier la montée des déchets au- dessus de la goulotte 81 et leur basculement dans ladite goulotte. The device 2 may comprise a system for gripping, lifting and tilting (not shown) containers of waste to the trough 8 1 as such. Such a system can be driven by hydraulic cylinders and / or pneumatic. It is intended to facilitate the handling of the containers, in particular the rise of the waste over the chute 8 1 and their tilting in said chute.
[0038] Toujours en relation avec la figure 1 , le dispositif 2 comprend une armoire électrique 22 avec des moyens de contrôle de la pompe à vide 16, du broyeur 82, de l'électrovanne 12 et éventuellement de l'unité de neutralisation des odeurs 20. Le dispositif 2 est alimenté en électricité via son armoire électrique 22 par un raccordement au réseau de distribution électrique. A cet effet, le dispositif, préférentiel lement l'armoire électrique 22, comprend une prise électrique (non représentée) destinée à recevoir un câble d'alimentation électrique raccordé à une prise du réseau de distribution. Le dispositif 2 est en effet destiné à être disposé à proximité de bâtiments, notamment industriels ou de commerce, pourvus de prises d'alimentations électrique. Still in connection with Figure 1, the device 2 comprises an electrical cabinet 22 with control means of the vacuum pump 16, the mill 8 2 , the solenoid valve 12 and optionally the neutralization unit of the 20. The device 2 is supplied with electricity via its electrical cabinet 22 by a connection to the electrical distribution network. For this purpose, the device, preferably the electrical cabinet 22, comprises an electrical socket (not shown) for receiving a power supply cable connected to a socket of the distribution network. The device 2 is indeed intended to be disposed near buildings, especially industrial or commercial, provided with power supply sockets.
[0039] L'utilisation du dispositif 2 peut avoir lieu de la manière suivante : le couvercle 83 de la goulotte de déversement 8 est soulevé par un opérateur afin de découvrir son ouverture. L'opérateur peut alors y déverser des déchets organiques, notamment du type alimentaire, par exemple au moyen d'un conteneur du type seau. Une fois les déchets déversés dans la goulotte 8, le couvercle 83 est amené en position de fermeture de la goulotte 8. Alternativement, un conteneur, notamment à roulettes, peut être engagé à un système de levage et de basculement en vue du déversement automatique des déchets dans la goulotte 81. Un opérateur peut alors actionner le mouvement ascendant du système à l'aide d'une manette à action maintenue. Le couvercle de la goulotte étant couplé à l'action du système de basculement s'ouvre afin de permettre le déversement du contenu du conteneur. Par action maintenue inverse de
la commande du système de basculement, le conteneur redescend, provoquant la fermeture du couvercle de la goulotte The use of the device 2 can take place as follows: the cover 8 3 of the spill chute 8 is raised by an operator to discover its opening. The operator can then pour in organic waste, particularly of the food type, for example by means of a container of the bucket type. Once the waste dumped in the trough 8, the cover 8 3 is brought into the closed position of the chute 8. Alternatively, a container, including wheels, can be engaged to a lifting and tilting system for automatic spill waste in the chute 8 1 . An operator can then operate the upward movement of the system with a sustained action lever. The lid of the chute being coupled to the action of the tilting system opens to allow the spill of the contents of the container. By action maintained inverse of the control of the tilting system, the container goes down again, causing the lid of the chute to close
[0040] L'opérateur peut alors actionner un bouton ou un moyen de commande quelconque (non représenté) afin d'activer le broyage des déchets au moyen du broyeur 82. Le broyage peut également être activé automatiquement par une détection de déchets. Le broyage est toutefois optionnel, si bien que l'opération de broyage décrite ci-avant est également optionnelle. L'électrovanne 12 est ensuite actionnée pour mettre la goulotte en communication fluidique avec l'enceinte en dépression de la cuve 6. S'en suit alors une aspiration des déchets via la conduite 10 vers l'intérieur de la cuve 6. L'ouverture de l'électrovanne 12 peut être sujette à une limitation de temps d'ouverture afin d'éviter de mettre l'enceinte de la cuve à la pression atmosphérique. Cette durée peut être comprise entre 2 et 60 secondes. The operator can then operate any button or any control means (not shown) to activate the grinding of the waste by means of the mill 8 2 . Grinding can also be activated automatically by waste detection. Grinding is however optional, so that the grinding operation described above is also optional. The solenoid valve 12 is then actuated to put the chute in fluid communication with the vacuum chamber of the tank 6. Then follows a suction of the waste via the pipe 10 to the inside of the tank 6. The opening the solenoid valve 12 may be subject to a limitation of opening time to avoid putting the chamber of the tank at atmospheric pressure. This duration can be between 2 and 60 seconds.
[0041] Un capteur de pression (non représenté) est prévu dans l'enceinte de la cuve. Le signal de pression de ce capteur est transmis à l'armoire électrique 22 qui va alors commander la mise en marche et l'arrêt de la pompe à vide 16 de manière à maintenir une dépression (par rapport à la pression atmosphérique) comprises entre 0.5 et 0.9 bar. Une temporisation, par exemple de quelques secondes, peut être prévue lorsque la dépression diminue au point d'atteindre la valeur minimale. En référence à la plage susmentionnée, la valeur minimale est de 0.5 bar. A pressure sensor (not shown) is provided in the chamber of the vessel. The pressure signal of this sensor is transmitted to the electrical cabinet 22 which will then control the start and stop of the vacuum pump 16 so as to maintain a vacuum (with respect to the atmospheric pressure) between 0.5 and 0.9 bar. A delay, for example of a few seconds, can be provided when the depression decreases to the point of reaching the minimum value. With reference to the aforementioned range, the minimum value is 0.5 bar.
[0042] La figure 2 illustre une unité de neutralisation des odeurs 20 du dispositif de la figure 1 , fonctionnant sur le principe de lavage des gaz, plus précisément sur le principe de lavage acido-basique. [0042] FIG. 2 illustrates a unit for neutralizing odors 20 of the device of FIG. 1, operating on the principle of washing gases, more specifically on the acid-base washing principle.
[0043] L'unité de neutralisation des odeurs 20 comprend une première colonne à bulles 24 de solution aqueuse, en l'occurrence de solution acide dont le pH peut être inférieur à 5, préférentiellement à 4. Les gaz en sortie de la pompe à vide 16 sont introduits en bas de la première colonne 24 afin de former des bulles dans la solution aqueuse acide et remonter vers la surface. Durant ce trajet, le gaz est en contact intime avec la solution et certaines molécules, notamment les mercaptans réagissent avec la solution et réalisent un transfert de masse vers la solution. Le flux gazeux
produit à la surface de la solution aqueuse de la première colonne 24 est guidé par une conduite vers le bas d'une deuxième colonne à bulles 26 à solution aqueuse, celle-ci étant cette fois basique, par exemple avec un pH supérieur à 8, préférentiellement 9. Similairement à la première colonne, les gaz vont former des bulles dans la solution aqueuse basique et seront en contact intime avec celle-ci durant leur parcours vers la surface. Des réactions chimiques peuvent avoir lieu et réaliser des transferts de masse. Le gaz quittant la surface de la solution aqueuse de la deuxième colonne 26 peut alors être évacué à l'atmosphère. The odor neutralization unit 20 comprises a first bubble column 24 of aqueous solution, in this case an acid solution whose pH may be less than 5, preferably 4. The gases at the outlet of the pump. vacuum 16 are introduced down the first column 24 to form bubbles in the acidic aqueous solution and back to the surface. During this journey, the gas is in intimate contact with the solution and some molecules, in particular the mercaptans react with the solution and carry out a mass transfer to the solution. The gas flow produced on the surface of the aqueous solution of the first column 24 is guided by a downward line of a second bubble column 26 to an aqueous solution, this being this time basic, for example with a pH greater than 8, preferentially 9. Similar to the first column, the gases will bubble into the basic aqueous solution and will be in intimate contact with it as they travel to the surface. Chemical reactions can take place and carry out mass transfers. The gas leaving the surface of the aqueous solution of the second column 26 can then be vented to the atmosphere.
[0044] Dans le cadre de la neutralisation des odeurs, une étape d'oxydation peut être superposée ou suivre le lavage acido-basique décrit ci-avant. L'opération est alors soit un lavage oxydant, soit un lavage acido-basique suivi d'une oxydation. Le fait d'oxyder le produit absorbé permet de régénérer en continu la solution de lavage. As part of the neutralization of odors, an oxidation step may be superimposed or follow the acid-base wash described above. The operation is then either an oxidizing wash or an acid-base wash followed by oxidation. Oxidizing the absorbed product allows the wash solution to be regenerated continuously.
[0045] Les solutions aqueuses de lavage peuvent comprendre du chlore, de l'eau oxygénée, et/ou de l'ozone. Aqueous wash solutions may include chlorine, hydrogen peroxide, and / or ozone.
[0046] A la figure 2, seules deux colonnes sont représentées. Il est entendu que davantage de colonnes peuvent être prévues, reliées entre-elles en série ou en parallèle. In Figure 2, only two columns are shown. It is understood that more columns can be provided, connected together in series or in parallel.
[0047] Les colonnes 24 et 26 peuvent comprendre chacune un robinet ou une vanne 28 de vidange de la solution aqueuse. La sortie de cette ou ces vannes peut être reliée à une évacuation ou à la cuve 6. En effet, ces solutions aqueuses peuvent être ajoutées aux déchets sans pour autant perturber leur processus de dégradation et de fermentation. The columns 24 and 26 may each comprise a valve or a valve 28 for draining the aqueous solution. The outlet of this or these valves can be connected to an evacuation or tank 6. In fact, these aqueous solutions can be added to the waste without disturbing their degradation and fermentation process.
[0048] Les colonnes 24 et 26 peuvent présenter une hauteur supérieure ou égale à 0.5 m, préférentiellement 1 m et présenter une largeur ou un diamètre inférieur ou égal à 0.2 m, préférentiellement 0.1 m. The columns 24 and 26 may have a height greater than or equal to 0.5 m, preferably 1 m and have a width or a diameter less than or equal to 0.2 m, preferably 0.1 m.
[0049] La figure 3 illustre deux configurations de remplissage de la cuve 3 du dispositif 2 de la figure 1. FIG. 3 illustrates two filling configurations of the tank 3 of the device 2 of FIG. 1.
[0050] A la configuration de gauche, les déchets sont acheminés par le point haut de la cuve 6, formant alors un amas 30 pouvant former un sommet en face de l'orifice 14 où débouche la conduite 10. Durant la fermentation des
déchets, une phase liquide peut se former et l'amas peut alors s'aplanir, permettant alors un remplissage satisfaisant. In the configuration on the left, the waste is conveyed by the high point of the tank 6, forming a cluster 30 that can form a peak in front of the orifice 14 where leads the pipe 10. During the fermentation of waste, a liquid phase can form and the cluster can then flatten out, allowing a satisfactory filling.
[0051] A la configuration de droite, les déchets sont acheminés par le point bas de la cuve 6. En fonction de la vitesse d'arrivée de déchets et de l'épaisseur de l'amas 30 en face de l'orifice 14', les déchets peuvent être projetés, notamment sur les côtés et favoriser le remplissage des côtés de la cuve 6. Il peut donc être intéressant de sélectionner une entrée des déchets dans la cuve par le haut et/ou par le bas, en fonction du profil de remplissage et de la nature des déchets. Dans le cadre de déchets à tendance sèche, il peut être avantageux d'utiliser l'entrée des déchets par le bas alors que pour les déchets à tendance humide, l'entrée par le haut peut être avantageuse. In the right configuration, the waste is conveyed by the low point of the tank 6. Depending on the speed of arrival of waste and the thickness of the cluster 30 in front of the orifice 14 ' , waste can be projected, especially on the sides and promote the filling of the sides of the tank 6. It may be interesting to select a waste inlet in the tank from above and / or from below, depending on the profile filling and the nature of the waste. In the case of dry-type waste, it may be advantageous to use the entry of waste from the bottom whereas for the wet-tending waste, entry from above can be advantageous.
[0052] La figure 4 illustre un camion 32 dans une configuration de chargement ou de déchargement du dispositif 2 de la figure 1 , illustrant la facilité de manutention du dispositif, similairement aux compacteurs de cartons. FIG. 4 illustrates a truck 32 in a loading or unloading configuration of the device 2 of FIG. 1, illustrating the ease of handling of the device, similarly to the carton compactors.
[0053] Le dispositif qui vient d'être décrit est particulièrement adapté pour stationner durant plusieurs semaines, voire plusieurs mois, auprès d'une entreprise, un commerce ou encore une cantine de collectivité (école, hôpital, etc.) produisant une certaine quantité de déchets organiques, notamment du type alimentaire. Ces déchets peuvent alors être régulièrement déversés dans la goulotte et ensuite aspirés sans difficulté et sans production d'odeurs nauséabondes, de coulée ou de développement de nuisibles (insectes, rats....). De plus, le fait que la cuve soit en permanence en dépression assure une fermentation contrôlée des déchets, les préparant de manière particulièrement avantageuse pour leur revalorisation, notamment par méthanisation. The device that has just been described is particularly suitable for parking for several weeks or months, with a company, a business or a community canteen (school, hospital, etc.) producing a certain amount organic waste, especially of the food type. This waste can then be regularly dumped into the chute and then sucked without difficulty and without producing foul odors, casting or development of pests (insects, rats ....). In addition, the fact that the tank is permanently in depression ensures a controlled fermentation of waste, preparing them particularly advantageously for their revaluation, in particular by methanation.
[0054] Pour ces industries, commerces ou collectivités, il suffit de commander la livraison d'un tel dispositif, notamment sous forme de location. Son remplacement par un autre, vide, ne sera nécessaire que lorsque le premier sera plein. La dépression dans la cuve permet de conserver et de faire fermenter les déchets sur plusieurs mois, en l'absence de réfrigération des déchets, et même dans des conditions estivales particulièrement chaudes. Les trajets en camion sont par conséquent
réduits et les déchets sont alors naturellement préparés pour leur valorisation.
For these industries, businesses or communities, simply order the delivery of such a device, especially in the form of rental. Its replacement by another, empty, will be necessary only when the first will be full. The depression in the tank allows to keep and ferment the waste over several months, in the absence of refrigeration of waste, and even in particularly hot summer conditions. Truck journeys are therefore reduced and the waste is then naturally prepared for their recovery.
