Definitions
- the present invention relates to a device for collecting, storing and transporting fermentable waste.
- Fermentable waste is residues of animal or plant origin made up of biodegradable organic matter. They can be broken down by microorganisms for which they are a source of food. There are several types of fermentable waste: food residues, from animal products: meat, milk, cheese, eggshells; food scraps of vegetable origin such as peelings of vegetables, fruits, used vegetable oils, coffee, tea; green bio-waste or garden residues such as grass clippings, dead leaves, manure, straw; residues consisting of paper and cardboard.
- Putrescible waste is remains of animal or vegetable origin that can degrade spontaneously and in a very short time, without the contribution of microorganisms. These are easily recoverable bio-waste. Not all fermentable waste is necessarily putrescible. On the other hand, all putrescible waste is fermentable waste. The difference between putrescible waste and fermentable waste is that not all fermentables have the ability to degrade spontaneously. Indeed, cardboard, paper and certain textiles of organic origin require a supply of specific microorganisms for their decomposition.
- Fermentable waste is likely to be treated by composting or methanization.
- Green waste, kitchen or vegetable scraps are examples of fermentable waste.
- Composting is an aerobic biological process of converting and upgrading organic matter into a stabilized, hygienic, potting-like product, rich in humic and mineral compounds, compost.
- Methanization is a natural biological process of degradation of anaerobic organic matter, that is to say in the absence of oxygen. It occurs naturally in certain sediments, marshes, rice fields, landfills, as well as in the digestive tract of certain animals: insects (termites) or vertebrates (ruminants ). A part some organic matter is degraded into methane, and another is used by methanogenic microorganisms for their growth and reproduction. The decomposition is not complete and leaves the digestate. Methanization is a technique implemented in a digester, also called a biogas reactor or methanizer, in which the process is accelerated and maintained to produce a usable methane, called biogas, or even biomethane after purification. Thus, fermentable waste, and in particular organic waste (or products from energy crops, solid or liquid) can provide energy.
- the digester is in the form of an airtight pit, into which black water, sludge, and additional organic compounds are poured to facilitate digestion. Gas forms in the sludge and rises to the surface, mixing the sludge in this process. The digested sludge accumulated at the bottom, forms part of the digestate, and can be drained and used as fertilizer.
- Document LU92556 discloses a system for storing and transporting fermentable waste provided with a device for storing fermentable waste comprising a container for storing the waste, a pump for establishing and maintaining a reduced pressure in the container, a mechanical installation. a storage facility for storing the container and the pump, and a transporter for transporting the container and the pump to and from the storage facility.
- the use of a pump to establish and maintain a reduced pressure in the container has the advantage of reducing the quantity of oxygen within the container, and thus of slowing down the decomposition of the waste. The nuisances associated with said decomposition can thus be delayed and the frequency of waste collection can be reduced.
- Document LU92859 discloses a device for storing and / or transporting organic waste comprising a hermetic tank intended to receive the waste; a vacuum pump fluidly connected to the waste tank and configured to suck the gases present in said tank and create a vacuum in said tank; and a waste discharge chute, fluidically connected by a pipe to the waste tank.
- the device further comprises a unit for neutralizing odors emitted by the gases sucked in by the vacuum pump.
- the truck moves from place to place to collect the waste over a short period of time, typically one or more days, until it is full.
- this waste does not decompose in a few days, even in high heat.
- the truck can then go and empty its contents at an organic waste treatment center.
- the storage device described in the document also implements the vacuum pump to transfer waste from a line of the device to the interior of the tank. The problems associated with the use of a vacuum pump previously mentioned are still present.
- Document LU 100173 discloses a device for storing and / or transporting organic waste, comprising a hermetic tank intended to receive the waste; a waste discharge chute, connected by a pipe to the waste tank and means for evacuating the gases present in the tank.
- the device comprises a unit for neutralizing odors emitted by the gases, connected from a fluid point of view to the tank by the discharge means and comprising at least one column of aqueous solution, the unit for neutralizing odors being configured to receive the gases from the vessel at the bottom of said one or more columns.
- the discharge of the waste and its transfer from the supply conduit to the hermetic tank can be carried out by suction or by a worm screw.
- the main problem associated with the implementation of at least one washing column lies in the development of the dosage of the acidic and basic reagents to be placed in the columns. Indeed, the latter strongly depend on the nature of the waste that will be inserted into the tank, a nature by definition unknown before its use. To be effective, the diffusion rate in the washing columns must be slow and constant (bubbling). However, this is not the case when a large influx of gas occurs, for example during the transfer of the contents of a garbage can from the crusher to an almost full tank. or in the case of the use of a powerful vacuum pump which will not allow the bubbling of the scents in the washing columns.
- One aim of the invention is in particular to remedy all or part of the aforementioned drawbacks.
- the present invention relates in particular to the treatment of putrescible fermentable waste. It can also be applied to the treatment of non-putrescible fermentable waste.

Description
DISPOSITIF DE COLLECTE, DE STOCKAGE ET DE TRANSPORTS DE DECHETS WASTE COLLECTION, STORAGE AND TRANSPORTATION DEVICE
FERMENTESCIBLES . FERMENTABLE.
Domaine technique Technical area
La présente invention se rapporte à un dispositif de collecte, de stockage et de transports de déchets fermentescibles. The present invention relates to a device for collecting, storing and transporting fermentable waste.
État de la technique antérieure State of the prior art
Les déchets fermentescibles sont des résidus d’origine animale ou végétale composés de matière organique biodégradable. Ils peuvent être décomposés par des micro-organismes pour lesquels ils représentent une source d’alimentation. Il existe plusieurs types de déchets fermentescibles : les résidus alimentaires, issus de produits d’origine animale : la viande, le lait, le fromage, les coquilles d’œufs ; les restes alimentaires d’origine végétale tels que les épluchures de légumes, de fruits, les huiles végétales usagées, le café, le thé ; les biodéchets verts ou résidus de jardinage tels que les tontes de gazon, les feuilles mortes, le fumier, la paille ; les résidus composés de papiers et cartons. Fermentable waste is residues of animal or plant origin made up of biodegradable organic matter. They can be broken down by microorganisms for which they are a source of food. There are several types of fermentable waste: food residues, from animal products: meat, milk, cheese, eggshells; food scraps of vegetable origin such as peelings of vegetables, fruits, used vegetable oils, coffee, tea; green bio-waste or garden residues such as grass clippings, dead leaves, manure, straw; residues consisting of paper and cardboard.
Les déchets putrescibles sont des restes d’origine animale ou végétale susceptibles de se dégrader spontanément et dans un délai très court, sans l’apport de micro-organisme. Ce sont des biodéchets facilement valorisables. Tous les déchets fermentescibles ne sont pas nécessairement putrescibles. En revanche tous les déchets putrescibles sont des déchets fermentescibles. La différence entre les déchets putrescibles et les déchets fermentescibles réside dans le fait que tous les fermentescibles n’ont pas forcément la capacité de se dégrader spontanément. En effet, le carton, le papier et certains textiles d’origine organique, nécessitent un apport de microorganismes spécifiques pour leur décomposition. Putrescible waste is remains of animal or vegetable origin that can degrade spontaneously and in a very short time, without the contribution of microorganisms. These are easily recoverable bio-waste. Not all fermentable waste is necessarily putrescible. On the other hand, all putrescible waste is fermentable waste. The difference between putrescible waste and fermentable waste is that not all fermentables have the ability to degrade spontaneously. Indeed, cardboard, paper and certain textiles of organic origin require a supply of specific microorganisms for their decomposition.
Les déchets fermentescibles sont susceptibles d'être traités par compostage ou méthanisation. Les déchets verts, les rebus de cuisine ou du potager sont des exemples de déchets fermentescibles. Fermentable waste is likely to be treated by composting or methanization. Green waste, kitchen or vegetable scraps are examples of fermentable waste.
Le compostage est un processus biologique aérobie de conversion et de valorisation des matières organiques en un produit stabilisé, hygiénique, semblable à un terreau, riche en composés humiques et minéraux, le compost. Composting is an aerobic biological process of converting and upgrading organic matter into a stabilized, hygienic, potting-like product, rich in humic and mineral compounds, compost.
La méthanisation (ou digestion anaérobie) est un processus naturel biologique de dégradation de la matière organique anaérobie, c’est-à-dire en absence d'oxygène. Il se produit naturellement dans certains sédiments, les marais, les rizières, les décharges, ainsi que dans le tractus digestif de certains animaux : insectes (termites) ou vertébrés (ruminants...). Une partie
de la matière organique est dégradée en méthane, et une autre est utilisée par les micro organismes méthanogènes pour leur croissance et reproduction. La décomposition n'est pas complète et laisse le digestat. La méthanisation est une technique mise en œuvre dans un digesteur, aussi appelé réacteur à biogaz ou méthaniseur, dans lequel on accélère et entretient le processus pour produire un méthane utilisable, dénommé biogaz, ou encore biométhane après épuration. Ainsi, les déchets fermentescibles, et notamment les déchets organiques (ou produits issus de cultures énergétiques, solides ou liquides) peuvent fournir de l'énergie. Methanization (or anaerobic digestion) is a natural biological process of degradation of anaerobic organic matter, that is to say in the absence of oxygen. It occurs naturally in certain sediments, marshes, rice fields, landfills, as well as in the digestive tract of certain animals: insects (termites) or vertebrates (ruminants ...). A part some organic matter is degraded into methane, and another is used by methanogenic microorganisms for their growth and reproduction. The decomposition is not complete and leaves the digestate. Methanization is a technique implemented in a digester, also called a biogas reactor or methanizer, in which the process is accelerated and maintained to produce a usable methane, called biogas, or even biomethane after purification. Thus, fermentable waste, and in particular organic waste (or products from energy crops, solid or liquid) can provide energy.
Il existe différentes formes et tailles de digesteurs. Dans une des techniques rudimentaires utilisées, le digesteur se présente sous la forme d'une fosse hermétique, dans laquelle sont déversées des eaux noires, des boues, et des composés organiques supplémentaires permettant de faciliter la digestion. Le gaz se forme dans les boues et remonte à la surface, mélangeant les boues par ce processus. Les boues digérées accumulées au fond, forment une partie du digestat, et peuvent être vidangées et utilisées comme engrais. There are different shapes and sizes of digesters. In one of the rudimentary techniques used, the digester is in the form of an airtight pit, into which black water, sludge, and additional organic compounds are poured to facilitate digestion. Gas forms in the sludge and rises to the surface, mixing the sludge in this process. The digested sludge accumulated at the bottom, forms part of the digestate, and can be drained and used as fertilizer.
Préalablement au compostage ou à la méthanisation de la matière fermentescible, il est nécessaire de stocker et de transporter la matière fermentescible vers un ou plusieurs lieux dans lesquels cette dernière pourra être traitée, soit par compostage, soit par méthanisation. Prior to composting or methanization of the fermentable material, it is necessary to store and transport the fermentable material to one or more places where the latter can be treated, either by composting or by methanization.
Du document LU92556, on connaît un système de stockage et de transport de déchets fermentescibles doté d’un dispositif de stockage de déchets fermentescibles comportant un conteneur pour stocker les déchets, une pompe pour établir et maintenir une pression réduite dans le conteneur, une installation mécanique de stockage pour stocker le conteneur et la pompe, et un transporteur pour transporter le conteneur et la pompe vers l’installation de stockage et à partir de celle-ci. Selon le document brevet, la mise en œuvre d’une pompe pour établir et maintenir une pression réduite dans le conteneur a pour avantage de diminuer la quantité d’oxygène au sein du conteneur, et ainsi de ralentir la décomposition des déchets. Les nuisances associées à ladite décomposition peuvent être ainsi retardées et la fréquence de collecte des déchets peut être réduite. Néanmoins, l’utilisation de la pompe pour établir une pression réduite dans le conteneur entraîne la mise sous aspiration des orifices d’entrée et de sortie. Pour pouvoir ajouter de la matière fermentescible broyée dans le réservoir de stockage qui est en légère dépression, il est nécessaire d’arrêter la pompe et d’introduire de l’oxygène dans le réservoir pour retrouver une pression atmosphérique. L’oxygène introduit accélère la décomposition des matières broyées dans le réservoir de stockage. Par ailleurs, il est ensuite nécessaire de mettre à nouveau en œuvre la pompe pour mettre le réservoir de stockage en légère dépression. Soit le débit de la pompe est important et le moyen de filtration des effluves est alors inefficace car le débit des gaz le traversant n’est pas nominal mais trop important, soit
le débit de la pompe est faible et il est alors nécessaire de patienter longtemps, c’est-à-dire de l’ordre de quelques heures selon le volume transféré, pour pouvoir recommencer à nouveau à introduire des matières fermentescibles broyées dans le réservoir de stockage. Document LU92556 discloses a system for storing and transporting fermentable waste provided with a device for storing fermentable waste comprising a container for storing the waste, a pump for establishing and maintaining a reduced pressure in the container, a mechanical installation. a storage facility for storing the container and the pump, and a transporter for transporting the container and the pump to and from the storage facility. According to the patent document, the use of a pump to establish and maintain a reduced pressure in the container has the advantage of reducing the quantity of oxygen within the container, and thus of slowing down the decomposition of the waste. The nuisances associated with said decomposition can thus be delayed and the frequency of waste collection can be reduced. However, using the pump to establish a reduced pressure in the container causes the inlet and outlet ports to be suctioned. In order to be able to add the crushed fermentable material to the storage tank, which is in slight depression, it is necessary to stop the pump and to introduce oxygen into the tank to regain atmospheric pressure. The oxygen introduced accelerates the decomposition of the ground material in the storage tank. Furthermore, it is then necessary to operate the pump again to put the storage tank in a slight depression. Either the pump flow rate is high and the scent filtration means is then ineffective because the gas flow rate passing through it is not nominal but too high, or the pump output is low and it is then necessary to wait a long time, that is to say of the order of a few hours depending on the volume transferred, to be able to start again to introduce crushed fermentable materials into the storage.
Du document LU92859, on connaît un dispositif de stockage et/ou de transport de déchets organiques comprenant une cuve hermétique destinée à recevoir les déchets ; une pompe à vide reliée d'un point de vue fluidique à la cuve à déchets et configurée pour aspirer les gaz présents dans ladite cuve et créer une dépression dans ladite cuve ; et une goulotte de déversement des déchets, reliée d'un point de vue fluidique par une conduite à la cuve à déchets. Le dispositif comprend, en outre, une unité de neutralisation d'odeurs émises par les gaz aspirés par la pompe à vide. Le document note que dans la pratique, un ralentissement de la décomposition des déchets n’est cependant pas particulièrement utile. En effet, lorsque le dispositif est transporté par un camion et si le camion est utilisé de manière efficace à l’occasion d’une tournée de collecte, le camion se déplace 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. Le dispositif de stockage décrit dans le document met également en œuvre la pompe à vide pour transférer les déchets depuis une conduite du dispositif vers l’intérieur de la cuve. Les problèmes liés à l’utilisation d’une pompe à vide précédemment évoqués sont toujours présents. Document LU92859 discloses a device for storing and / or transporting organic waste comprising a hermetic tank intended to receive the waste; a vacuum pump fluidly connected to the waste tank and configured to suck the gases present in said tank and create a vacuum in said tank; and a waste discharge chute, fluidically connected by a pipe to the waste tank. The device further comprises a unit for neutralizing odors emitted by the gases sucked in by the vacuum pump. The document notes that in practice, slowing the decomposition of waste is not particularly useful, however. In fact, when the device is transported by a truck and if the truck is used effectively during a collection round, the truck moves from place to place to collect the waste over a short period of time, typically one or more days, until it is full. However, this waste does not decompose in a few days, even in high heat. Once the tank is full, the truck can then go and empty its contents at an organic waste treatment center. The storage device described in the document also implements the vacuum pump to transfer waste from a line of the device to the interior of the tank. The problems associated with the use of a vacuum pump previously mentioned are still present.
Du document LU 100173, on connaît un dispositif de stockage et/ou de transport de déchets organiques, comprenant une cuve hermétique destinée à recevoir les déchets ; une goulotte de déversement des déchets, reliée par une conduite à la cuve à déchets et des moyens d'évacuation des gaz présents dans la cuve. Le dispositif comprend une unité de neutralisation d'odeurs émises par les gaz, reliée d'un point de vue fluidique à la cuve par les moyens d'évacuation et comprenant au moins une colonne de solution aqueuse, l'unité de neutralisation d'odeurs étant configurée pour recevoir les gaz de la cuve dans le bas de ladite ou desdites colonnes. Le déversement des déchets et leur transfert depuis le conduit d’ amenée vers la cuve hermétique peut être réalisé par aspiration ou par une vis sans fin. Le principal problème lié à la mise en œuvre d’au moins une colonne de lavage réside dans la mise au point du dosage des réactifs acides et basiques à mettre dans les colonnes. En effet, ces derniers dépendent fortement de la nature des déchets qui seront insérés dans la citerne, nature par définition inconnue avant son utilisation. Pour être efficace, la vitesse de diffusion dans les colonnes de lavages doit être lente et constante (bullage). Or, ce n’est pas le cas lorsqu’un afflux important de gaz survient, par exemple lors du transfert du contenu d’une poubelle du broyeur vers une cuve quasi-pleine
ou dans le cas de l’utilisation d’une pompe à vide puissante qui ne permettra pas le bullage des effluves dans les colonnes de lavage. Document LU 100173 discloses a device for storing and / or transporting organic waste, comprising a hermetic tank intended to receive the waste; a waste discharge chute, connected by a pipe to the waste tank and means for evacuating the gases present in the tank. The device comprises a unit for neutralizing odors emitted by the gases, connected from a fluid point of view to the tank by the discharge means and comprising at least one column of aqueous solution, the unit for neutralizing odors being configured to receive the gases from the vessel at the bottom of said one or more columns. The discharge of the waste and its transfer from the supply conduit to the hermetic tank can be carried out by suction or by a worm screw. The main problem associated with the implementation of at least one washing column lies in the development of the dosage of the acidic and basic reagents to be placed in the columns. Indeed, the latter strongly depend on the nature of the waste that will be inserted into the tank, a nature by definition unknown before its use. To be effective, the diffusion rate in the washing columns must be slow and constant (bubbling). However, this is not the case when a large influx of gas occurs, for example during the transfer of the contents of a garbage can from the crusher to an almost full tank. or in the case of the use of a powerful vacuum pump which will not allow the bubbling of the scents in the washing columns.

The feed device may alternatively, or in addition, comprise a container lifter, preferably actuated electrically or hydraulically, arranged to empty a rolling bin.
Dans le mode de réalisation représenté, le réservoir de stockage est en matière polymère, métal doux ou inox. Le réservoir de stockage peut être recouvert, au moins partiellement, d’une couche de protection et/ou de renforcement, par exemple de type PTFE (polytétrafluoroéthylène) , feuille d’inox ou époxy. In the embodiment shown, the storage tank is made of polymer material, soft metal or stainless steel. The storage tank may be covered, at least partially, with a protective and / or reinforcing layer, for example of the PTFE (polytetrafluoroethylene) type, stainless steel sheet or epoxy.
Selon un mode de réalisation représenté sur la figure 2, le dispositif de transfert 108 peut comporter un tuyau ou un cylindre 116 en col de cygne raccordé au-dessus du réservoir 110. According to one embodiment shown in FIG. 2, the transfer device 108 may comprise a pipe or a swan neck cylinder 116 connected above the reservoir 110.
Toujours en référence à la figure 2, le réservoir de stockage 110 comporte des disques brise-vague 118, disposés verticalement. Ces disques qui ont le double avantage d’optimiser le remplissage complet du réservoir 110 limitent les risques de renversement lors du transport. Il est ainsi possible d’éviter des coups de bélier. Still with reference to FIG. 2, the storage tank 110 comprises wave-breaking discs 118, arranged vertically. These discs, which have the double advantage of optimizing the complete filling of the tank 110, limit the risk of overturning during transport. It is thus possible to avoid water hammer.
Le réservoir de stockage 110 comporte en outre des capteurs de niveaux 120. Ils peuvent être placés de part et d’autre des brise- vagues 118 et améliorent la lecture du niveau réel de remplissage du réservoir. The storage tank 110 further includes level sensors 120. They can be placed on either side of the wave breakers 118 and improve the reading of the actual filling level of the tank.
La courbe N illustre un étalement possible des matières broyées dans le réservoir de stockage 110. Curve N illustrates a possible spread of the ground materials in the storage tank 110.
En référence à la figure 1 , la trémie 104 peut être pourvue d’un revêtement anti-adhérent, par exemple de type PTFE ou PP (polypropylène). En particulier, le polypropylène présente un coefficient de frottement très faible et une bonne tenue aux acides et aux bases. Referring to Figure 1, the hopper 104 may be provided with a non-stick coating, for example of the PTFE or PP (polypropylene) type. In particular, polypropylene has a very low coefficient of friction and good resistance to acids and bases.
Le dispositif 100 peut en outre comporter deux trappes anti-odeur (non représentées) . The device 100 can also include two anti-odor hatches (not shown).
La première trappe anti-odeur est formée par un couvercle de la trémie 104 muni d’un joint d’étanchéité et est ainsi disposée en amont de la trémie, selon le sens d’écoulement des matières fermentescibles. Le couvercle a au moins deux fonctions, Tune de sécurité, l’autre d’étanchéité de la trémie. Fermé, il permet le déclenchement du broyeur 106 en toute sécurité et retient les odeurs des restes de déchets qui n’auront pas été acheminés dans le réservoir de stockage 110. The first odor trap is formed by a hopper cover 104 provided with a seal and is thus arranged upstream of the hopper, according to the direction of flow of the fermentable materials. The lid has at least two functions, one for safety, the other for sealing the hopper. Closed, it allows the triggering of the crusher 106 in complete safety and retains the odors of the remains of waste that will not have been sent to the storage tank 110.
La deuxième trappe anti-odeur est formée d’une vanne guillotine étanche, disposée entre le dispositif de transfert 108 et le réservoir de stockage 110. La vanne guillotine permet d’une part de s’assurer que les matières broyées ne puissent pas revenir vers le broyeur 106 et d’autre part d’assurer l’étanchéité à l’égard de l’air à l’extérieur du dispositif. Ce montage est particulièrement intéressant lorsque le dispositif de transfert présente un tuyau en col de cygne.
Selon une possibilité le dispositif de transfert 108 peut comporter une pompe à vide.The second anti-odor trap is formed by a sealed guillotine valve, arranged between the transfer device 108 and the storage tank 110. The guillotine valve makes it possible, on the one hand, to ensure that the crushed materials cannot return to the crusher 106 and on the other hand to ensure the seal against the air outside the device. This assembly is particularly advantageous when the transfer device has a gooseneck pipe. According to one possibility, the transfer device 108 may include a vacuum pump.
Alternativement, le dispositif de transfert est à pression positive selon le sens d’écoulement des déchets fermentescibles. Le dispositif de transfert 108 peut par exemple être une vis sans fin, aussi appelée vis d’Archimède, ou une pompe péristaltique. Alternatively, the transfer device is at positive pressure depending on the direction of flow of the fermentable waste. The transfer device 108 can for example be a worm, also called an Archimedes screw, or a peristaltic pump.
Le dispositif de vidage fonctionne par gravité ou aspiration, par exemple au moyen d’une vanne agricole ou d’un trou d’homme 112. The emptying device works by gravity or suction, for example by means of an agricultural valve or a manhole 112.
Selon un mode de réalisation représenté sur la figure 3, le réservoir de stockage 110 peut en outre comporter des moyens de chauffe 122 agencé pour chauffer les matières broyées. According to an embodiment shown in FIG. 3, the storage tank 110 may further include heating means 122 arranged to heat the ground materials.
Ainsi, il est possible de chauffer le réservoir de stockage 110 une fois plein à une température minimale de 70 °C pendant une durée minimale d’une heure afin de réaliser la phase d’hygiénisation des déchets fermentescibles de façon anaérobique. Cette phase est obligatoire pour les déchets fermentescibles pouvant contenir des sous-produits animaux de type C3 (SPAN C3). Réaliser cette opération dans le réservoir permet par la suite de vider le réservoir chez n’importe quel méthaniseur quelles que soient ses installations. En effet, le coût d’une installation d’hygiénisation chez un méthaniseur étant élevée, peu en sont pourvus. Par ailleurs, un méthaniseur utilisant essentiellement des produits agricoles ne saurait rentabiliser une installation d’hygiénisation. Thus, it is possible to heat the storage tank 110 once full to a minimum temperature of 70 ° C for a minimum period of one hour in order to carry out the hygienization phase of the fermentable waste anaerobically. This phase is mandatory for fermentable waste which may contain type C3 animal by-products (SPAN C3). Carrying out this operation in the tank then makes it possible to empty the tank at any methanizer regardless of its installations. Indeed, the cost of a hygienization installation in a methanizer being high, few are equipped with it. Furthermore, a methanizer using mainly agricultural products cannot make a sanitation installation profitable.
Des dispositifs de pilotage, tels des calculateurs, peuvent être prévus pour piloter les moyens de chauffe 122. Control devices, such as computers, can be provided to control the heating means 122.
Selon un mode de réalisation représenté sur la figure 4, le dispositif de filtration d’effluves 114 est disposé (raccordé fluidiquement) entre le réservoir de stockage 110 et un dispositif d’évacuation d’effluves 124, générées par les matières broyées et/ou déchets fermentescibles, du dispositif 100. According to one embodiment shown in FIG. 4, the corona filtration device 114 is arranged (fluidly connected) between the storage tank 110 and a corona discharge device 124, generated by the ground materials and / or fermentable waste, device 100.
Le dispositif de filtration d’effluves 114 est un media solide de filtration, de préférence un filtre à charbon ou un biofiltre The corona filtration device 114 is a solid filtration media, preferably a carbon filter or a biofilter
Alternativement, le dispositif de filtration d’effluves est de type ionisation, photocatalyse, traitement UV, ozonation, ou brûlage. Alternatively, the corona filtration device is of the ionization, photocatalysis, UV treatment, ozonation, or burning type.
Alternativement, le dispositif de filtration d’effluves est de type colonnes de lavage. Alternatively, the corona filtration device is of the washing column type.
Le dispositif de filtration d’effluves comporte une vanne de surpression 128, disposée entre le réservoir de stockage 110 et le dispositif de filtration d’effluves 114, de préférence tarée à 0,1 bar. The corona filtration device comprises a pressure relief valve 128, arranged between the storage tank 110 and the corona filtration device 114, preferably calibrated at 0.1 bar.
Dans l’exemple représenté, le réservoir de stockage 110 comporte en outre une soupape de sécurité 130 tarée à 0,3 bar à l’interface entre le réservoir de stockage 110 et l’extérieur du dispositif 100.
La vanne de surpression 128 et la soupape de sécurité 130 sont disposées de la manière la plus éloignée possible de la vanne agricole ou du trou d’homme. In the example shown, the storage tank 110 further comprises a safety valve 130 calibrated at 0.3 bar at the interface between the storage tank 110 and the outside of the device 100. The overpressure valve 128 and the safety valve 130 are arranged as far as possible from the agricultural valve or the manhole.
Par exemple, la vanne agricole ou le trou d’homme peuvent être disposés d’un côté, dit côté avant, du dispositif 100, tandis que la vanne 128 et la soupape 130 sont disposées de l’autre côté, dit côté arrière, du dispositif 100. For example, the agricultural valve or the manhole can be arranged on one side, called the front side, of the device 100, while the valve 128 and the valve 130 are arranged on the other side, called the rear side, of the device. device 100.
Comme illustrée sur la figure 4, le dispositif 100 peut comprendre un détendeur 126, disposé entre le réservoir de stockage 110 et le dispositif de filtration d’effluves 114. As illustrated in Figure 4, the device 100 may include a pressure reducer 126, arranged between the storage tank 110 and the corona filtration device 114.
En ce cas, la vanne de surpression 128 peut être disposée entre le réservoir de stockage 110 et le dispositif de filtration d’effluves 114. In this case, the pressure relief valve 128 can be placed between the storage tank 110 and the corona filtration device 114.
Le détendeur 126 est judicieusement choisi et présente un volume supérieur ou égal à la quantité maximum de déchets ingérable par la machine en un cycle, par exemple de 240 L. Ainsi, on s’assure que le dispositif de filtration d’effluves 114 fonctionne à pression nulle. Le dispositif de filtration d’effluves 114 présente ainsi le meilleur débit de filtration. The regulator 126 is carefully chosen and has a volume greater than or equal to the maximum quantity of waste ingestible by the machine in one cycle, for example 240 L. Thus, it is ensured that the corona filtration device 114 operates at zero pressure. The corona filtration device 114 thus has the best filtration rate.
Le dispositif 100 peut en outre comporter un dispositif de stockage d’effluve, fluidiquement disposé entre le dispositif de filtration d’effluves 114 et le dispositif d’évacuation d’effluves 124. The device 100 may further include a corona storage device, fluidly disposed between the corona filtration device 114 and the corona discharge device 124.
