Abstract
Dispositif pour agiter de manière centrifuge et anaérobique de la matière à pouvoir méthanogène afin de produire du biogaz. L’invention concerne un dispositif permettant d’agiter l’ensemble de la matière sans zone morte et en rotation par rapport au bâti fixe. Il est constitué d’une enveloppe (1) présentant un pignon amont(2) et aval(3) sur lequel tourne l’axe (12) et le tambour (11) solidaire entre eux. Le dispositif selon l’invention est particulièrement destiné à la méthanisation. Figure pour l’abrégé : Fig. 2Device for centrifuging and anaerobically stirring methanogenic material in order to produce biogas. The invention relates to a device for agitating all of the material without a dead zone and in rotation with respect to the fixed frame. It consists of a casing (1) having an upstream (2) and downstream (3) pinion on which the axis (12) and the drum (11) integral with one another rotates. The device according to the invention is particularly intended for methanization. Figure for the abstract: Fig. 2
Description
La présente invention concerne un dispositif pour digérer des déchets à pouvoir méthanogène (agricole, organique, ménager, etc…) avec une agitation centrifuge en milieu anaérobiqueThe present invention relates to a device for digesting waste with methanogenic power (agricultural, organic, household, etc.) with centrifugal agitation in an anaerobic environment.
L’agitation de la matière des digesteurs se fait :
- par un ou plusieurs arbres munis de pales avec une motorisation extérieure
- et/ou par immersion d’un agitateur immergé (mixer)
- et/ou par l’envoi de flux (gaz ou liquide) à l’aide de buses afin de créer un courant d’agitation.The agitation of the digester material is done:
- by one or more shafts fitted with blades with external motorization
- and/or by immersion of an immersed stirrer (mixer)
- and/or by sending a stream (gas or liquid) using nozzles in order to create a stirring current.
L’innovation est sur le fait que l’agitation soit effectuée par le mouvement du contenant du digesteur.The innovation is in the fact that the agitation is carried out by the movement of the digester container.
Ce contenant est un cylindre horizontal, il sera appelé « tambour ». Il repose sur des paliers fixes et est entrainé à l’aide d’une couronne. Il comporte des grilles intérieures afin de mélanger la matière.This container is a horizontal cylinder, it will be called "drum". It rests on fixed bearings and is driven using a crown. It has interior grids to mix the material.
L’alimentation et le soutirage se fait par l’axe de rotation du tambour du digesteur. L’axe est creux jusqu’à rentrer suffisamment dans le tambour. Une ouverture vers le tambour et créer afin de dirigé le flux.The feeding and the withdrawal is done by the axis of rotation of the drum of the digester. The axis is hollow until it enters sufficiently into the drum. An opening to the drum and create to direct the flow.
L’enveloppe est étanche afin de pouvoir agiter la matière de façon anaérobique.The envelope is sealed so that the material can be stirred anaerobically.
Les dessins annexés illustrent l’invention :The accompanying drawings illustrate the invention:
En référence à ces dessins, le dispositif comporte une enveloppe extérieure (1) avec un pignon dit « amont » (2) et un pignon dit « aval » (3). Le toit (4) de l’enveloppe (1) contient un disque de rupture (5) et une coupole d’extraction du gaz (6).With reference to these drawings, the device comprises an outer casing (1) with a so-called “upstream” pinion (2) and a so-called “downstream” pinion (3). The roof (4) of the casing (1) contains a bursting disc (5) and a gas extraction cupola (6).
Le pignon amont (2) reçoit le palier amont (7) qui comporte l’entrée du flux et la couronne d’entrainement (8)The upstream pinion (2) receives the upstream bearing (7) which includes the flow inlet and the drive crown (8)
Le pignon aval (3) reçoit le palier aval (9) avec la sortie du flux ainsi que la porte de visite (10).The downstream pinion (3) receives the downstream bearing (9) with the flow outlet as well as the inspection door (10).
Sur la coupe, nous apercevons le tambour (11) de forme cylindrique fixé sur l’arbre (12).On the cut, we see the drum (11) of cylindrical shape fixed on the shaft (12).
Les grilles (13) servent de pales d’agitations et sont fixes et solidaires du tambour et de l’axe.The grids (13) serve as agitation blades and are fixed and integral with the drum and the shaft.
L’enveloppe (1) est entièrement calorifugé (14) avec un réseau de chauffage appliqué sur ce calorifuge.The envelope (1) is fully insulated (14) with a heating network applied to this insulation.
Pour le passage du gaz entre le tambour et l’intérieur de l’enveloppe, c’est l’enchainement des ensembles : vanne (15) puis soupape (16), sur la circonférence du tambour qui permettre le dégazage par intermittence.For the passage of gas between the drum and the inside of the casing, it is the sequence of assemblies: valve (15) then valve (16), on the circumference of the drum which allows degassing intermittently.
