Description

L'invention concerne l'application du four décrit au brevet principal comme carbonisateur pour déchets de toute nature produits par l'agriculture, l'industrie ou l'habitat
Un but de l'invention est de fournir un carbonisateur qui convienne pour le traitement de déchets de granulométrie très variable, par exemple des poussières de végétaux, des coques de noix, des noyaux de cerises, des morceaux de bois de quelques centimètres.The invention relates to the application of the furnace described in the main patent as a carbonizer for waste of all kinds produced by agriculture, industry or housing
An object of the invention is to provide a carbonizer which is suitable for the treatment of very variable particle size waste, for example plant dust, nut shells, cherry stones, pieces of wood a few centimeters.

Le carbonisateur de l'invention convient, de façon typique, pour traiter les déchets des forêts. The carbonizer of the invention is typically suitable for treating forest waste.

L'aptitude du carbonisateur de l'invention à fonctionner dans une gamme large de granulométrie est due au fait qu'il est à lit mobile et aussi au fait qu'il peut fonctionner jusqu'à une température élevée, soit typiquement une température de la gamme de 200 à 7000C ou meme une température pouvant atteindre 800-9000C bien que la gamme précédente soit préférée. The ability of the carbonizer of the invention to operate in a wide range of particle sizes is due to the fact that it is a moving bed and also to the fact that it can operate up to a high temperature, typically a temperature of the range from 200 to 7000C or even a temperature up to 800-9000C although the previous range is preferred.

Outre le traitement des déchets forestiers mentionné plus haut, le carbonisateur de l'invention convient également pour le traitement des déchets suivants
- déchets de scierie : chutes, sciures
- biomasse : paille, coques d'arachide, paddy
(balle de riz), tannées (écorce de chêne
humides), coques de coton, marc de café,
déchets de palme,grignons d'olive, noyaux de
fruits, tourbe, etc
- refus de compostage,
- déchets industriels : papiers, plastiques, boi
caoutchoucs,
- déchets textiles : laine, coton, plastiques
(moquettes).In addition to the treatment of forest waste mentioned above, the carbonizer of the invention is also suitable for the treatment of the following waste
- sawmill waste: scrap, sawdust
- biomass: straw, peanut shells, paddy
(rice husk), tanned (oak bark
wet), cotton shells, coffee grounds,
palm waste, olive pomace, kernels
fruit, peat, etc
- refusal of composting,
- industrial waste: paper, plastics, wood
rubbers,
- textile waste: wool, cotton, plastics
(carpets).

Cette liste n'est pas limitative. This list is not exhaustive.

L'incinerateur comprend une chambre de carbonisation comme la chambre de combustion du four décrit au brevet principal, à savoir une chambre de carbonisation rotative présentant une ouverture ou se trouve la sortie d'un conduit fixe servant à alimenter la chambre avec le produit à traiter, cette chambre communiquant en outre avec urnentrée d'un conduit fixe, séparée de ladite sortie et servant à évacuer de la chambre les gaz dégagés par la carbonisation du déchet, l'entrée du conduit de gaz se trouvant également dans ladite ouverture. The incinerator includes a carbonization chamber like the combustion chamber of the furnace described in the main patent, namely a rotary carbonization chamber having an opening or the outlet of a fixed duct serving to supply the chamber with the product to be treated , this chamber further communicating with the inlet of a fixed conduit, separated from said outlet and serving to evacuate from the chamber the gases released by the carbonization of the waste, the inlet of the gas conduit also being in said opening.

Des moyens sont prévus pour rendre étanche à l'air la chambre de carbonisation et pour recycler partiellement le gaz produit par la carbonisation vers le brûleur de la chambre afin de démarrer et de maintenir les réactions de pyrolyse. Means are provided to make the carbonization chamber airtight and to partially recycle the gas produced by the carbonization to the burner of the chamber in order to start and maintain the pyrolysis reactions.

Si tout le gaz combustible produit par la carbonisation n'est pas utilisé, une fourniture d'air comburant secondaire peut être maintenue. If all the combustible gas produced by carbonization is not used, a supply of secondary combustion air can be maintained.

On décrira ci-après un carbonisateur conforme à la présente invention, en référence aux figures du dessin joint sur lequel
- la figure 1 est une coupe longitudinale du carbonisateur
- la figure 2 est une coupe selon le plan B-B de la figure 1, et
- la figure 3 est un schéma de l'ouverture de la chambre de carbonisation où débouchent simultanément le conduit des déchets alimentant le carhonisateur et le conduit d'évacuation des gaz dégagés par la carbonisation.A carbonizer according to the present invention will be described below, with reference to the figures in the accompanying drawing in which
- Figure 1 is a longitudinal section of the carbonizer
FIG. 2 is a section along the plane BB of FIG. 1, and
- Figure 3 is a diagram of the opening of the carbonization chamber where the waste pipe feeding the carhonizer and the gas evacuation pipe released by the carbonization open simultaneously.

Le carbonisateur comporte une cellule 1, étanche à l'air, qui constitue une chambre de carbonisation inclinée. Cette cellule, tournante ou oscillante, est de forme conique, cylindrotronconique ou cylindrique. The carbonizer comprises a cell 1, airtight, which constitutes an inclined carbonization chamber. This rotating or oscillating cell is conical, cylindrotronconic or cylindrical.

A son extrémité supérieure, la chambre présente une ouverture 2, de section circulaire, obstruée par une façade fixe 3. Cette façade fixe est percée de carneaux 4 et 5 situés côte à cote. Un joint périphérique 18 assure l'étanchéité de l'ouverture autour de la façade 3. At its upper end, the chamber has an opening 2, of circular section, obstructed by a fixed facade 3. This fixed facade is pierced with flues 4 and 5 located side by side. A peripheral seal 18 seals the opening around the facade 3.

Le carneau 4, de forme carrée ou rectangulaire, constitue la sortie d'un conduit 6 d'alimentation de la chambre avec les produits à traiter, c'est-à-dire les déchets à carboniser.  The flue 4, of square or rectangular shape, constitutes the outlet of a conduit 6 for supplying the chamber with the products to be treated, that is to say the waste to be carbonized.

De façon en soi connue, ces déchets descendent par gravité d'une trémie 7 et sont poussés dans le conduit 6 ver la sortie 4 par un vérin poussoir ou autre système d'alimentatic connue. In a manner known per se, this waste descends by gravity from a hopper 7 and is pushed into the conduit 6 to the outlet 4 by a push cylinder or other known alimentatic system.

Le carneau 5, en forme de portion de cercle, constitue l'entrée d'un conduit de gaz 9 qui relie la chambre de carbonisation à une chambre auxiliaire 12. Une partie du gaz de carbonisation est recyclée partiellement de la chambre 12, par un conduit 15, vers le brûleur 21 placé devant une ouverture 20 de l'extrémité basse de la chambre. Cette ouverture 20 est rendue périphériquement étanche à l'air par un joint 19. The flue 5, in the form of a portion of a circle, constitutes the inlet of a gas conduit 9 which connects the carbonization chamber to an auxiliary chamber 12. Part of the carbonization gas is partially recycled from the chamber 12, by a conduit 15, towards the burner 21 placed in front of an opening 20 of the lower end of the chamber. This opening 20 is made peripherally airtight by a seal 19.

Le gaz recyclé vers le brûleur sert a démarrer à maintenir les réactions de pyrolyse. The gas recycled to the burner is used to start to maintain the pyrolysis reactions.

Dans une réalisation préférée (figure 1), une partie des gaz de carbonisation est conduite par un conduit 14 vers un brûleur 23 d'un sécheur 24 destiné à sécher les déchets avant leur introduction dans la chambre de carbonisation. Les dechets séchés sont évacués du sécheur par un transporteur 25 qu les conduit à la trémie 7 du four. Cette trémie est équipée d' extracteur étanche empêchant toute introduction d'air dans le four 1.  In a preferred embodiment (FIG. 1), part of the carbonization gases is led through a conduit 14 to a burner 23 of a dryer 24 intended to dry the waste before it is introduced into the carbonization chamber. The dried waste is removed from the dryer by a conveyor 25 which leads them to the hopper 7 of the oven. This hopper is fitted with a sealed extractor preventing any introduction of air into the oven 1.

Les déchets carbonisés dans la chambre 1 circulent à contre-courant des flux gazeux, ce qui permet d'évit les pointes de température risquant de fondre les cendres. Ils sortent de la chambre par la sortie 20 et tombent dans un extracteur étanche 26 à double clapet.  The carbonized waste in chamber 1 circulates against the flow of gas flows, which avoids temperature spikes which risk melting the ashes. They leave the chamber via outlet 20 and fall into a sealed extractor 26 with a double valve.
