Description
Dispositif pour la production de méthane
à partir de déchets cellulosiques.
L'invention concerne un dispositif pour la production de méthane à partir de déchets cellulosiques.Device for the production of methane
from cellulosic waste.
The invention relates to a device for the production of methane from cellulosic waste.
On connaît déjà suivant le brevet principal un dispositif qui se compose d'une cuve dont la partie supérieure est obturée par une boche fixée au bord de la cuve et dont les bords plongent à l'intérieur de la cuve contenant le fumier ou les déchets cellulosiques, afin d'assurer l'étanchéité. Already known according to the main patent a device which consists of a tank whose upper part is closed by a boche fixed to the edge of the tank and whose edges plunge inside the tank containing manure or cellulosic waste , to ensure watertightness.
les gaz et notamment le méthane, qui résultent de la ferm entation des bactéries anaérobies, s'accumulent alors sous la bâche qui constitue en même temps un moyen de stockage. gases and in particular methane, which result from the closure of anaerobic bacteria, then accumulate under the tarpaulin which at the same time constitutes a means of storage.
Le prob-lème essentiel provenant de ces dispositifs connus réside dans les manipulations importantes qu'il est nécessaire de réaliser pour remplacer les déchets épuisés par de nouveaux déchets cellulosiques. The essential prob-lem from these known devices resides in the important manipulations that it is necessary to perform to replace the spent waste with new cellulosic waste.
Cet inconvénient est d'autant plus important que la masse de déchets contenus dans la cuve est très importante. This drawback is all the more important as the mass of waste contained in the tank is very large.
Pour remédier à cet inconvénient, on a ainsi prévu suivant le brevet prinçipal, de disposer les déchets dans des poches en filet qui, après fermeture, sont plongées dans la cuve. Suivant ce procédé, la manipulation du fumier se réduit à la manipulation de poches fermées qu'il est possible de déplacer à l'aide d'un treuil. To remedy this drawback, provision has thus been made, according to the main patent, for disposing the waste in mesh pockets which, after closing, are immersed in the tank. According to this process, the handling of manure is reduced to the handling of closed pockets which can be moved using a winch.
La présente invention a pour but des perfectionnements à ces dispositifs connus et concerne à cet effet un dispositif pour la production de méthane à partir du fumier ou de déchets cellulosiques comportant une cuve contenant le fumier ou les déchets cellulosiques, et obturée à sa partie supérieure par une boche fixée de manière amovible au bord de la cuve, dispositif caractérisé en ce que le fumier est disposé dans la cuve sur un filet accroché de manière amovible sur le bord de la cuve et stappxyant sur la paroi interne de cette cuve. The present invention aims to improve these known devices and for this purpose relates to a device for the production of methane from manure or cellulosic waste comprising a tank containing manure or cellulosic waste, and closed at its upper part by a tank removably attached to the edge of the tank, device characterized in that the manure is disposed in the tank on a net hung detachably on the edge of the tank and stappxyant on the inner wall of this tank.
Suivant une autre caractéristique de l'invention, la cuve est en coupe de forme-trapézoidale. According to another characteristic of the invention, the tank is in section of trapezoidal shape.
Suivant une autre-caractéristique de l'invention la cuve trapézoidale est de forme demi-hexagonale. According to another characteristic of the invention, the trapezoidal tank is of semi-hexagonal shape.
Suivant une autre caractéristique de l'invention, la cuve est divisée transversalement par des cloisons, chacune de ces divisions contenant un filet. According to another characteristic of the invention, the tank is divided transversely by partitions, each of these divisions containing a net.
Suivant une autre caractéristique de l'invention, les cloisons de la cuve sont pourvues d'une ouverture à leur base. According to another characteristic of the invention, the partitions of the tank are provided with an opening at their base.
L'invention est représentée, à titre d'exemple non limitatif, sur les dessins ci-joints, dans lesquels
- la figure l est une vue en coupe transver sale d'un mode de réalisation de l'invention
- la figure 2 est une vue en élévation de la cuve de la figure i en cours de déchargement
- la figure 3 est une vue en coupe du dispositif de l'invention illustrant les opérations de chargement et de déchargement du digesteur.The invention is shown, by way of non-limiting example, in the accompanying drawings, in which
- Figure l is a dirty cross-sectional view of an embodiment of the invention
- Figure 2 is an elevational view of the tank of Figure i during unloading
- Figure 3 is a sectional view of the device of the invention illustrating the loading and unloading operations of the digester.
La présente invention a en conséquence pour but la réalisation d'un digesteur qui simplifie au maximum les opérations de chargement et le déchargement du fumier ou des déchets cellulosiques dans et hors de la cuve. The present invention therefore aims to achieve a digester which simplifies the operations of loading and unloading manure or cellulosic waste in and out of the tank as much as possible.
Ce dispositif se compose d'une cuve l, de préférence en matière plastique, qui est enterrée dans le sol et dont l'ouverture supérieure est obturée, en cours de fonctionnement par une bâche 2. This device consists of a tank 1, preferably made of plastic, which is buried in the ground and the upper opening of which is closed, during operation by a cover 2.
La cuve l est en coupelle forme trapézoïdale et de préférence de forme demi-hexagonale pour permettre une extraction aisée du fumier. Elle est réalisée à partir de deux éléments identiques qui sont assemblés longitudinalement en 11 à la base de la cuve. The tank 1 is in a trapezoidal shape and preferably in a semi-hexagonal shape to allow easy extraction of the manure. It is made from two identical elements which are assembled longitudinally at 11 at the base of the tank.
'axe longitudinal de lacuve est de préf6'- rence orienté perpendiculairement au sud, et l'un des bords de cette cuve comporte un capteur solaire 3 orienté de façon à recevoir le maximum d'ensoleillement et permettre un réchauffement optimum du liquide contenu dans la cuve afin d'activer les réactions chimiques, et donc d'augmenter la production de méthane. the longitudinal axis of the tank is preferably oriented perpendicular to the south, and one of the edges of this tank comprises a solar collector 3 oriented so as to receive the maximum amount of sunshine and allow optimum heating of the liquid contained in the tank in order to activate the chemical reactions, and therefore to increase the production of methane.
L'échangeur 3 de ce capteur solaire comporte à cet effet des conduits 31 qui plongent dans le liquide de la cuve afin de le faire circuler à l'intérieur du capteur et d'utiliser directement ce liquide comme moyen d'échange thermique. The exchanger 3 of this solar collector comprises for this purpose conduits 31 which plunge into the liquid of the tank in order to circulate it inside the collector and to use this liquid directly as a means of heat exchange.
Cette cuve demi-hexagonale 1 est divisée transversalement par des cloisons 4 pourvues à leur base d'une ouverture 41 permettant la circulation du liquide d'une des divisions 5 à l'autre, et donc de maintenir le liquide contenu dans chacune de ces divisions à un niveau. iden- tique et sensiblement constant. This half-hexagonal tank 1 is divided transversely by partitions 4 provided at their base with an opening 41 allowing the circulation of the liquid from one of the divisions 5 to the other, and therefore of maintaining the liquid contained in each of these divisions at one level. identical and substantially constant.
Chacune de ces divisions 5 comporte un filet 6 qui repose sur l'ensemble du fond de la. cuve l et. qui, de préférence, remonte le long des parois transversales par les cloisons 4. Each of these divisions 5 has a net 6 which rests on the entire bottom of the. tank l and. which preferably rises along the transverse walls via the partitions 4.
Ces filets, disposés dans chacune des divi- sions 5 sont accrochés de manière amovible par leur bord sur des crochets il prévus sur les bords de la cuve et des cloisons 4 de façon que le fumier ou bs déchets cellulosiques puissent être déversés sur ces filets. These nets, arranged in each of the divisions 5, are detachably hooked by their edges on hooks 11 provided on the edges of the tank and partitions 4 so that manure or cellulose waste can be poured onto these nets.
Ainsi, après avoir oté la bâche 2 recouvrant l'une des divisions 5, il est possible de déverser les déchets cellulosiques dans cette cuve à l'aide d'un tracteur 7 pourvu d'une benne
Lorsque le limier ou les déchets cellulosiques de cette division sont épuisés, l'opération de déchargement de ces déchets hors de la cuve est effectuée de manière rapide à l'aide d'un tracteur 8.Thus, after removing the cover 2 covering one of the divisions 5, it is possible to dump the cellulosic waste in this tank using a tractor 7 provided with a bucket
When the bloodhound or the cellulosic waste of this division is exhausted, the operation of unloading this waste out of the tank is carried out quickly using a tractor 8.
Pour celà, il suffit de décrocher le filet 6 des crochets 1 1 du bord de la cuve, sauf le long de son bord 12, le bord opposé 61 du filet étant accroché au tracteur 8 par l'intermédiaire d'un cible 9. For this, it suffices to unhook the net 6 from the hooks 11 on the edge of the tank, except along its edge 12, the opposite edge 61 of the net being hooked to the tractor 8 by means of a target 9.
le tracteur soulève alors le filet et donc le fumier ou es déchets cellulosiques afin de les extraire de la cuve, et de déverser ces déchets sur la surface de déchargement 10 voisine de la cuve. the tractor then lifts the net and therefore the manure or cellulosic waste in order to extract it from the tank, and dump this waste on the unloading surface 10 adjacent to the tank.
Cette surface de déchargement 10 est de préférence inclinée vers la cuve 1 afin de permettre 1' écou- lement et donc la récupération du ltRide pouvant subsister dans le fumier ou les déchets extraits. This unloading surface 10 is preferably inclined towards the tank 1 in order to allow the flow and therefore the recovery of the ltRide which may remain in the manure or the extracted waste.
De préférence, la biche 2 seraxréalisée en plusieurs éléments indépendanb-recouvrant chacun l'une des divisions de la -cuve, de façon qu'il soit possible de charger et décharger l'une de ces divisions alors que les autres sont encore en fonctionnement. Preferably, the doe 2 will be made up of several independent elements each covering one of the divisions of the tank, so that it is possible to load and unload one of these divisions while the others are still in operation.
Egalement, afin de permettre les opérations d'accrochage et de décrochage du filet, sur le bord de la cuve ou au cible 9, des passerelles 10, de préférence amovibles, seront prévues au-dessus des cloisons 4 (voir fig. 2). Also, in order to allow the operations of hooking and unhooking the net, on the edge of the tank or on the target 9, gangways 10, preferably removable, will be provided above the partitions 4 (see fig. 2).
