Abstract
Description
La présente invention se rapporte & la fabrication du noir de carbone, et concerne plus particulièrement un proc- de et un appareil de récupération du noir de carbone emprisonné dans une gangue de fibres de verre. The present invention relates to the manufacture of carbon black, and more particularly relates to a process and an apparatus for recovering carbon black trapped in a gangue of glass fibers.
Les problèmes d'écologie et de récupération des matières recyclables en remplacement de matières premières naturelles ont pris de plus en plus d'importance au cours des dix dernières annCes. Cette récupération et ce recyclage apportent aussi l'avantage de supprimer la nécessité d'liminer des déchets. The problems of ecology and recovery of recyclable materials to replace natural raw materials have become more and more important during the last ten years. This recovery and recycling also brings the advantage of eliminating the need to dispose of waste.
Le brevet des Etats-Unis dtAmOrique n 4 038 100 ddorit un procédé de rEcupération de ce genre. Il décrit la manière selon laquelle une composition de noir animal peut être produite à partir d'un caoutchouc qui contient des hydrocarbures polymdrisés et du noir de carbone par pyrolyse et broyage du caoutchouc avec des billes chauffes pendant une durée suffisante pour vaporiser et dépolymériser les hydrocarbures et produire ainsi une matière noire solide en très petites particules.Le noir animal ainsi produit est exempt de caoutchouc non décomposé et de coke et son coéfficient de décoloration par la benzine est supérieur à 70 %, de préférence 90 *. Les bandages pneumatiques tels que ceux des automobiles, des camions, etc.. constituent la source de caoutchouc principalement concernée par ce brevet. US patent 4,038,100 describes such a recovery process. It describes the manner in which an animal black composition can be produced from a rubber that contains polymerized hydrocarbons and carbon black by pyrolysis and grinding the rubber with heated beads for a time sufficient to vaporize and depolymerize the hydrocarbons and thus produce a solid dark matter in very small particles. The animal black thus produced is free of undecomposed rubber and of coke and its bleaching coefficient by benzine is greater than 70%, preferably 90 *. Pneumatic tires such as those of cars, trucks, etc. constitute the source of rubber mainly concerned by this patent.
Etant donné que la plus grande partie des bandages pneumatiques actuellement produits contiennent des matières darmature en fibre de verre et/ou en acier, le noir animal produit par le procédé mentionné ci-dessus contient des particules indésirables de fibre de verre et d'acier qui doivent être liminsses. Les particules d'acier sont facilement dliminees par un dispositif magnétique en vue d'être recyclées. Les fibres de verre sont limnées en faisant passer le noir animal par un tamis à mailles fines que les particules de noir de carbone extrêmement fines peuvent traverser mais qui retient les particules de fibres de verre formant un matelas de fibres, par exemple d'une épaisseur de 25 à 100 mm. Since most of the pneumatic tires currently produced contain fiberglass and / or steel reinforcing materials, the animal black produced by the above mentioned process contains undesirable particles of fiberglass and steel which must be removed. The steel particles are easily removed by a magnetic device for recycling. The glass fibers are eliminated by passing the animal black through a fine mesh screen which the particles of extremely fine carbon black can pass through but which retains the particles of glass fibers forming a mat of fibers, for example of a thickness from 25 to 100 mm.
Les matelas qui sont sortis du tamis selon le brevet précité représentent un sous-produit actuellement perdu contenant deux constituants potentiellement utilisables, la fibre de verre et le noir de carbone. Les matelas contiennent gEnéralement de 30 à 50 % de fibre de verre et de 50 à 70 % de noir de carbone. L'invention a pour objet de proposer un procédé et un appareil de récupération de ces deux sous-produits potentiellement utiles et d'éliminer les matelas sous forme d'un sous-produit perdu dans le procEd pr- cité. The mattresses which have come out of the sieve according to the aforementioned patent represent a currently lost by-product containing two potentially usable constituents, fiberglass and carbon black. Mattresses generally contain 30 to 50% fiberglass and 50 to 70% carbon black. The object of the invention is to propose a method and an apparatus for recovering these two potentially useful by-products and to eliminate the mattresses in the form of a by-product lost in the above-mentioned process.
L'invention permet d'atteindre ce résultat grssce à un procédé qui consiste essentiellement à faire passer le mate
las dans un agitateur de manière à le disperser partiellement en un nuage de particules de fibres de verre et de noir de carbone libre, à faire passer un courant d'air dans le nuage avec une vitesse suffisante pour entraîner les particules libres de noir de carbone et les particules de fibres de verre exemptes de carbone, sans entratner les particules de fibres de verre combinées avec du carbone, à sdparer les particules libres de noir de carbone des particules de fibres de verre exemptes de noir de carbone, à recueillir les particules libres et sépares de noir de carbone sous forme d'un premier sous-produit utilisable, et biler les particules séparées de fibres de verre pour éliminer le noir de carbone qui subsiste et qu'elles ont entratné de manière à former des particules de fibre de verre exemptes de noir de carbone sous forme d'un second sous-produit uti lisable. Selon un mode de réalisation, l'opération de combuS- tion des particules de fibres de verre se fait dans une pla- ge de 500 à 5500C. The invention makes it possible to achieve this result by virtue of a process which essentially consists in passing the mat
weary in an agitator so as to partially disperse it into a cloud of particles of glass fibers and free carbon black, to pass a current of air through the cloud with a speed sufficient to entrain the free particles of carbon black and the carbon-free glass fiber particles, without entraining the glass fiber particles combined with carbon, to separate the carbon black free particles from the carbon black free glass fiber particles, to collect the free particles and separated carbon black as a first usable by-product, and biling the separated particles of glass fibers to remove the carbon black which remains and which they entrained so as to form particles of glass fiber free of carbon black in the form of a second useful by-product. According to one embodiment, the combustion operation of the glass fiber particles is carried out in a range of 500 to 5500C.
L'invention concerne également un appareil destins à la mise en oeuvre de ce procédé, comportant une enceinte avec une entre et une sortie disposés de manière à crier une colonne d'air ascendante dans l'enceinte lorsque l'air la traverse entre l'entrée et la sortie, un agitateur sous forme de plusieurs lames rotatives disposées dans l'enceinte de manière à rompre une partie au moins des matelas qui sont placés dans l'enceinte en un nuage do particules de fibres de verre et de particules libres de noir de carbone une source de force motrice qui entraîne l'agitateur, un dispositif relié l'enceinte pour y crier un colorant d'air entre l'entrée et la sortie, la vitesse de ce courant d'air étant suffisante pour que les particules libres de noir de carbone et les particules libres de fibres de verre exemptes de carbone soient seules entraînées vers le haut contre leur propre poids par la colonne d'air ascendante afin de sortir de enceinte par sa sortie, un premier séparateur branchu de manière à re ce voir le courant d'air sortant de l'enceinte et qui sépare les particules exemptes de noir de carbone du courant d'air (par exemple dans le prisent mode de ralitation un séparateur à cyclone, un second sépara- teur relié au premier séparateur pour en rocevoir le courant d'air et en séparer les particules libres de noir de carbo ne (par exemple un filtre à sac dans le prisent mode de réa- lisation), et un dispositif de combustion relit au premier séparateur pour en recevoir les particules séparées exemptes de noir de carbone et leur faire subir une combustion de manitre à brûler le reste de noir de carbone qu'elles entras nent. The invention also relates to an apparatus intended for the implementation of this method, comprising an enclosure with an inlet and an outlet arranged so as to shout an ascending column of air in the enclosure when the air passes through it between the inlet and outlet, an agitator in the form of several rotating blades arranged in the enclosure so as to break at least part of the mattresses which are placed in the enclosure in a cloud of particles of glass fibers and free particles of black of carbon a source of motive force which drives the agitator, a device connected to the enclosure for shouting an air dye between the inlet and the outlet, the speed of this current of air being sufficient for the free particles of carbon black and the free particles of carbon-free glass fibers alone are drawn up against their own weight by the ascending air column in order to leave the enclosure by its exit, a first separator branched so as to re re see the air flow coming out of the enclosure and which separates the particles free of carbon black from the air current (for example in the current slowdown mode a cyclone separator, a second connected separator to the first separator to collect the air flow and to separate the free particles of carbon black therefrom (for example a bag filter in the present embodiment), and a combustion device connected to the first separator to receiving the separated particles free of carbon black and subjecting them to undergo a combustion in order to burn the remainder of carbon black which they collect.
D'autres caractéristiques et avantages de l'invention seront mieux compris à la lecture de la description qui va suivre d'un exemple de réalisation et en se référant au dessin annexé sur lequel
la figure unique est une vue simplifiée en élévation et en coupe partielle d'un appareil selon l'intention destins à la mise en oeuvre du procédé.Other characteristics and advantages of the invention will be better understood on reading the description which follows of an exemplary embodiment and with reference to the appended drawing in which
the single figure is a simplified view in elevation and in partial section of an apparatus according to the intention intended for the implementation of the method.
La figure montre donc que l'appareil selon l'invention comporte essentiellement une enceinte 10 avec une entre 12 près de son extrémité inférieure et une sortie 14 près de son extrémitd supérieure. L'entrée 12 est agencée de ma- nitre à recevoir des morceaux de matelas 16 de fibres de verre, provenant par exemple d'une bande convoyeuse 18 qui ntest pas concerne par l'invention.L'entrée 20 d'un sdpa- rateur à cyclone 22 est branchée sur la sortie 14. Le sépa- rateur à cyclone 12 est du type entrain par un moteur de manière qu'en fonctionnement, de l'air 24 soit aspird par l'entrée 12 de l'enceinte 10 en formant une colonne d'air ascendante, indiquée par la flèche 26, à l'intérieur de l'encette 10 et sortant par la sortie 14 vers le séparateur à cyclone 22, par son entrée 20. The figure therefore shows that the apparatus according to the invention essentially comprises an enclosure 10 with a between 12 near its lower end and an outlet 14 near its upper end. The entrance 12 is arranged as a master to receive pieces of mattress 16 of glass fibers, coming for example from a conveyor belt 18 which is not concerned with the invention. The entry 20 of a separator cyclone 22 is connected to the output 14. The cyclone separator 12 is of the type driven by a motor so that, in operation, air 24 is drawn through the inlet 12 of the enclosure 10 forming an ascending column of air, indicated by arrow 26, inside the casing 10 and exiting via the outlet 14 towards the cyclone separator 22, through its inlet 20.
Un agitateur, désigné globalement par 28, est disposé dans le fond de l'enceinte 10. L'agitateur 28 comporte un arbre 30 accouplé, à l'extdrieur de de l'enceinte 10, avec un moteur d'entratnement 32 qui le fait tourner lorsqu'il est connecté à une source d'alimentation appropriée, non repré- sentée, par le ctble d'alimentation 34. A l'intérieur de l'enceinte 10, plusieurs lames rotatives 36 sont fixées sur l'arbre 30. Quand ce dernier tourne, les lames 36 tournent rapidement avec lui de manière à rompre les morceaux de matelas 16 de fibres de verre qui viennent en contac-t avec elles, sous forme de particules 38 de fibres de verre et de particules libres 40 de noir de carbone.Les particules libres 40 de noir de carbone et des particules 38' de fibre de verre qui sont exemptes de noir de carbone adhdrent sont très légères et sont forcées vers le haut par les lames tournantes 36 en formant un nuage 42 de particules 38' et 40 à l'intérieur de l'enceinte 10. Le courant d'air 24 pene- trant par entrée 12, formant une colonne ascendante 26, et sortant par la sortie 14 traverse le nuagè 42 en entrai- nant les particules légères 38' et 40 contre leur propre poids, en les faisant sortir par la sortie 14.Les morceaux non rompus des matelas 16 de fibres de verre et des particules 38 de fibres de verre plus lourdes ne sont pas entrat- nées par le courant d'air 24 et retombent sur les lames rotatives 36 pour être recyclées jusqu'8 ce qu'une partie suffisamment dispersée sorte de. l'enceinte 10 avec les particules plus légères. Dans le but de faciliter cette opéra- tion, la partie inférieure 44 de l'enceinte 10 est inclinez vers les lames rotatives 36 afin de guider les matelas 16 et de recycler les particules 38 dans ces lames. An agitator, generally designated by 28, is arranged in the bottom of the enclosure 10. The agitator 28 comprises a shaft 30 coupled, outside of the enclosure 10, with a drive motor 32 which does so rotate when connected to an appropriate power source, not shown, by the power cable 34. Inside the enclosure 10, several rotary blades 36 are fixed on the shaft 30. When the latter rotates, the blades 36 rotate rapidly with it so as to break the pieces of mattress 16 of glass fibers which come into contact with them, in the form of particles 38 of glass fibers and of free particles 40 of black The free particles 40 of carbon black and particles 38 'of glass fiber which are free of carbon black adhere are very light and are forced upwards by the rotating blades 36 by forming a cloud 42 of particles 38' and 40 inside the enclosure 10. The air flow 24 penetrating by inlet 12, forming an ascending column 26, and leaving via outlet 14 passes through the cloud 42, driving the light particles 38 ′ and 40 against their own weight, causing them to exit through outlet 14. The unbroken pieces of mattress 16 of glass fibers and particles 38 of heavier glass fibers are not entrained by the air stream 24 and fall on the rotating blades 36 to be recycled until a sufficiently dispersed part comes out of. enclosure 10 with the lighter particles. In order to facilitate this operation, the lower part 44 of the enclosure 10 is inclined towards the rotary blades 36 in order to guide the mattresses 16 and to recycle the particles 38 in these blades.
L'air 24 qui pénètre par l'entrée 20 du séparateur à cyclone 22 entratne avec lui les particules 38' de fibres de verre exemptes de noir de carbone et les particules libres 40 de noir de carbone. A l'intérieur du séparateur à cyclone 22, les particules 38' de fibre de verre sont séparées de l'air 24 qui contient les particules libres 40 de noir de carbone.Les particules 38' de fibres de verre tombent par le conduite 46 dans un leur 48 tandis que l'air 24 et les particules libres 40 de. noir de carbone passent par la conduite 50 vers l'entrée d'un séparateur 52, par exemple un filtre à sac susceptible d'éliminer les particules libres 40 de noir de carbone sous forme d'un premier sous-produit utilisable, et l'air propre 24 s'échappe, pratiquement exempt de particules 40 de noir de carbone. The air 24 which enters through the inlet 20 of the cyclone separator 22 carries with it the particles 38 'of glass fibers free of carbon black and the free particles 40 of carbon black. Inside the cyclone separator 22, the particles 38 'of glass fiber are separated from the air 24 which contains the free particles 40 of carbon black. The particles 38' of glass fibers fall through line 46 into one their 48 while the air 24 and the free particles 40 of. carbon black pass through line 50 to the inlet of a separator 52, for example a bag filter capable of eliminating the free particles 40 of carbon black in the form of a first usable by-product, and the clean air 24 escapes, practically free of particles 40 of carbon black.
Le brdleur 48 est associé avec un dispositif désigné globalement par 54 qui en maintient la température à une valeur de 500 à 5500C de préférence. A cette température, le noir de carbone qui reste sur les particules 38 de fibres de verre est brtlé et il est éliminé dans les gaz d'échappement 56 tandis que les particules 38' de fibre.de verre sortent sous forme d'un second sous-produit utilisable du procédé et de l'appareil. The burner 48 is associated with a device generally designated by 54 which maintains the temperature at a value of 500 to 5500C preferably. At this temperature, the carbon black which remains on the particles 38 of glass fibers is burnt and it is eliminated in the exhaust gases 56 while the particles 38 ′ of glass fibers exit in the form of a second sub -usable product of the process and the device.
I1 apparat ainsi que grâce au procédé et à l'appareil selon l'invention, les matelas 16 de fibres de verre constituant un sous-produit du brevet précité sont complètement dissociés en leun constituants utiles, ce qui supprime le problème d'élimination de ces matelas et permet d'obtenir de la fibre de verre (c'est à dire les particules 38p) et du noir de carbone (c1est à dire les particules 40) sous forme de sous-produits utiles. I1 thus appears that thanks to the method and to the apparatus according to the invention, the glass fiber mattresses 16 constituting a by-product of the aforementioned patent are completely dissociated into one useful constituents, which eliminates the problem of elimination of these mattress and makes it possible to obtain fiberglass (ie particles 38p) and carbon black (ie particles 40) in the form of useful by-products.
Bien entendu, diverses modifications peuvent entre appor tées par l'homme de l'art au procédé et à l'appareil décrits et illustrés à titre d'exemple nullement limitatif sans sortir du cadre de l'invention. Of course, various modifications can be made by those skilled in the art to the process and to the apparatus described and illustrated by way of non-limiting example without departing from the scope of the invention.
