Objects, characteristics and advantages of the invention appear from the description which follows, given by way of nonlimiting example, with reference to the appended drawings in which:
  • FIG. 1 is a plan view of a system according to the invention,
  • FIG. 2 is an elevation view of an inlet portion of the furnace of this system,
  • FIG. 3 is a cross-sectional view along the line AA of FIG. 2, and
  • Figure 4 is an enlarged view of the connection of a panel 4 to its support.

La figure 1 montre le schéma de principe du système et les figures 2 à 4 en présentent certains détails constructifs.Figure 1 shows the block diagram of the system and Figures 2 to 4 show some constructive details.

Le système selon l'invention comporte un réacteur intégrant en un seul appareil une chambre 1 d'introduction des produits à traiter et dans laquelle ces produits subissent une déshydratation, une chambre de thermolyse 2 dans laquelle les produits, partiellement ou totalement déshydratés, sont portés à la température de décomposition thermique, par exemple aux environs de 600°C (typiquement entre 400°C et 750°C) et une chambre de refroidissement 3 où les résidus solides du traitement thermique sont amenés à une température ordinaire.The system according to the invention comprises a reactor integrating in a single device a chamber 1 for introducing the products to be treated and in which these products undergo dehydration, a thermolysis chamber 2 in which the products, partially or totally dehydrated, are brought at the thermal decomposition temperature, for example around 600 ° C (typically between 400 ° C and 750 ° C) and a cooling chamber 3 where the solid residues from the heat treatment are brought to an ordinary temperature.

La transformation thermolytique dans le réacteur est avantageusement effectués en absence totale d'oxygène libre à température moyenne de 600°C.The thermolytic transformation in the reactor is advantageously carried out in the total absence of free oxygen at an average temperature of 600 ° C.

Les produits de décomposition - gaz incondensables, hydrocarbures lourds, charbon - sont contrôlés en continu à la sortie du système et sont éventuellement recyclés pour traitement complémentaire.The decomposition products - incondensable gases, heavy hydrocarbons, coal - are continuously monitored at the outlet of the system and are optionally recycled for further treatment.

Le fonctionnement à cette température n'induit pas d'usure marqués du système dont la durée de vie est ainsi prolongée et le coût de fonctionnement réduit.Operation at this temperature does not induce marked wear of the system, the service life of which is thus extended and the operating cost reduced.

Les chambres sont isolées les unes des autres de façon sensiblement étanche, par des portes guillotine 23 actionnées par des vérins ; la porte entre les chambres 1 et 2 et la porte entre les chambres 2 et 3 sont mobiles verticalement dans des logements étanches, la traversée des vérins de levage se faisant par presse-étoupe. En outre des portes étanches sont prévues à l'entrée de la chambre 1 et à la sortie de la chambre 3 grâce à quoi les zones de déshydratation 1 et de refroidissement sont, à volonté, isolées vis à vis de l'extérieur et/ou de la zone de thermolyse 2 ; elles peuvent être mobiles verticalement ou horizontalement ou encore autour d'une articulation selon les dimensions du réacteur, l'espace disponible et le libre choix du concepteur.The chambers are insulated from each other in a substantially sealed manner, by guillotine doors 23 actuated by jacks; the door between chambers 1 and 2 and the door between chambers 2 and 3 are movable vertically in watertight housings, the crossing of the lifting cylinders being by cable gland. In addition, watertight doors are provided at the entrance to chamber 1 and at the exit from chamber 3 whereby the dehydration 1 and cooling zones are, at will, isolated from the outside and / or thermolysis zone 2; they can be movable vertically or horizontally or around a joint according to the dimensions of the reactor, the space available and the free choice of the designer.

On appréciera que l'étanchéité assurée par les portes d'entrée et de sortie se fait entre l'extérieur et des zones 1 et 3 de températures modérées, très inférieures à celles de la chambre 2.It will be appreciated that the seal provided by the entry and exit doors is between the outside and zones 1 and 3 of moderate temperatures, much lower than those of chamber 2.

L'introduction des produits et de l'extraction des résidus sont ainsi réalisés, pour éviter l'entrée d'air dans la chambre 2, par des sas gui isolent alternativement selon les besoins la chambre de déshydratation de la chambre de thermolyse quand on introduit les produits dans la chambre de déshydratation et la chambre de thermolyse de la chambre de refroidissement quand on extrait les résidus de cette troisième chambre.The introduction of the products and the extraction of the residues are thus carried out, to avoid the entry of air into the chamber 2, by airlocks which isolate alternately as required the dehydration chamber from the thermolysis chamber when one introduces the products in the dehydration chamber and the thermolysis chamber of the cooling chamber when the residues from this third chamber are extracted.

Les chambres 1 et 2 du réacteur sont calorifugées (repère 27) pour limiter les déperditions calorifiques.Chambers 1 and 2 of the reactor are lagged (item 27) to limit heat loss.

Les chambres 1 et 2 sont munies de moyens de chauffage de tous types connus appropriés, dont deux exemples sont donnés sous les références 4 et 5. La température de la chambre 2 est par exemple maintenue aux alentours de 600°C tandis que celle de la chambre 1, inférieure, est maintenue au dessus de 100°C, par exemple aux environs de 120°C.Chambers 1 and 2 are provided with heating means of any suitable known type, two examples of which are given under references 4 and 5. The temperature of chamber 2 is for example maintained at around 600 ° C. while that of chamber 1, lower, is maintained above 100 ° C., for example around 120 ° C.

Des panneaux radiants catalytiques 4, munis de résistances incorporées 25 destinées à leur mise en température pour permettre le phénomène d'oxydation catalytique de gaz d'alimentation, sont représentés en plafond des chambres 1 et 2 mais peuvent également être mis sur les parois latérales. Ces panneaux sont placés dans des logements étanches vis à vis de l'extérieur. Le détail de la figure 4 montre le principe de fixation d'un panneau 4 sur la paroi interne du réacteur et la position d'un joint d'étanchéité repéré 26 mis en place pour obliger le mélange gazeux d'alimentation (de préférence oxygène, gaz de pyrolyse) à passer par le panneau catalytique 4 où il est oxydé. La chambre 3 peut être équipée d'un système (non représenté) de refroidissement des résidus solides et de récupération de la chaleur par réchauffage des gaz gui alimentent les panneaux radiants catalytiques.Catalytic radiant panels 4, provided with built-in resistors 25 intended to heat them up to allow the catalytic oxidation phenomenon of feed gas, are shown on the ceiling of the chambers 1 and 2 but can also be placed on the side walls. These panels are placed in watertight housings with respect to the outside. The detail of FIG. 4 shows the principle of fixing a panel 4 on the internal wall of the reactor and the position of a seal identified 26 put in place to force the gaseous supply mixture (preferably oxygen, pyrolysis gas) to pass through the catalytic panel 4 where it is oxidized. Chamber 3 can be equipped with a system (not shown) for cooling solid residues and recovering heat by heating the gases which supply the catalytic radiant panels.

Des résistances électriques 5 sont alimentées à partir d'un transformateur 6 ; ces résistances sont ici représentées à l'intérieur du réacteur, collées à la paroi (mais peuvent être mises à l'extérieur), l'alimentation électrique étant faite en utilisant des traversées étanches.Electric resistors 5 are supplied from a transformer 6; these resistances are here represented inside the reactor, glued to the wall (but can be put outside), the electrical supply being made by using watertight bushings.

La chambre 2 est maintenue en dépression, typiquement à une pression inférieure ou égale à 800 mbar, voire 500 mbars. De préférence, la même pression règne dans les chambres 1, 2 et 3.Chamber 2 is kept under vacuum, typically at a pressure less than or equal to 800 mbar, or even 500 mbar. Preferably, the same pressure prevails in chambers 1, 2 and 3.

Le mélange gazeux extrait de la chambre 2 va dans un laveur de gaz 9 débouchant dans un bloc de décantation 13 et alimenté en eau froide par un bassin 14 où l'eau à la sortie du bac de décantation 13 est traitée par les méthodes classiques de la chimie des eaux. Les hydrocarbures condensés et le charbon séparés de la phase aqueuse dans le bac 13 sont envoyés dans un réservoir de stockage 17 où ils seront repris pour utilisation.The gaseous mixture extracted from chamber 2 goes into a gas washer 9 opening into a settling block 13 and supplied with cold water by a basin 14 where the water at the outlet of the settling tank 13 is treated by conventional methods of water chemistry. Hydrocarbons condensed and the carbon separated from the aqueous phase in the tank 13 are sent to a storage tank 17 where they will be taken up for use.

Les gaz non condensés à la sortie du bac 9 sont aspirés par un groupe de pompage 10 dont le refoulement débite dans un bac laveur 11 où le gaz carbonique est éliminé par addition de carbonate de potassium, par exemple, dans l'eau venant du bac 14. A la sortie du bac 11 le gaz épuré est comprimé par le compresseur 12 et stocké dans un réservoir 16.The non-condensed gases at the outlet of the tank 9 are sucked in by a pumping group 10, the discharge of which flows into a washing tank 11 where the carbon dioxide is eliminated by adding potassium carbonate, for example, in the water coming from the tank. 14. On leaving the tank 11, the purified gas is compressed by the compressor 12 and stored in a tank 16.

Ce gaz comprimé est ici envoyé aux panneaux radiants catalytiques 4 après passage dans un mélangeur 15 où arrive également de l'air comprimé de provenance quelconque en 18, ou encore, selon les cas d'application, de l'oxygène pur venant d'un stockage extérieur. Le mélange gazeux traverse un récupérateur 7 où il est échauffé afin d'améliorer le bilan thermodynamique de l'oxydation catalytique. La figure 1 montre en effet une sortie des gaz de catalyse de la chambre 1 ; ces gaz, composés essentiellement de gaz carbonique et de vapeur d'eau provenant de la déshydratation et de l'oxydation catalytique, traversent le récupérateur 7 où ils sont refroidis. Ils sont aspirés par un groupe de pompage 8 dont le refoulement débite sur une cheminée 19.This compressed gas is here sent to the catalytic radiant panels 4 after passing through a mixer 15 which also receives compressed air from any source at 18, or alternatively, depending on the application, pure oxygen coming from a outdoor storage. The gas mixture passes through a recuperator 7 where it is heated in order to improve the thermodynamic balance of the catalytic oxidation. FIG. 1 indeed shows an exit of the catalysis gases from the chamber 1; these gases, mainly composed of carbon dioxide and water vapor from dehydration and catalytic oxidation, pass through the recuperator 7 where they are cooled. They are sucked up by a pumping group 8, the discharge of which flows onto a chimney 19.

La figure 2 montre un chariot 20 dans lequel sont placés les produits à traiter ; le chariot passe d'une chambre à l'autre par l'intermédiaire d'un système pignon crémaillère 21.FIG. 2 shows a carriage 20 in which the products to be treated are placed; the carriage passes from one room to the other via a rack and pinion system 21.

Un arbre d'entraînement 22 assure le mouvement synchronisé des chariots.A drive shaft 22 ensures the synchronized movement of the carriages.

Les gaz sont extraits des chambres 1 et 2 par des carneaux 24 situés en extrémité des chambres et en plancher de façon à entraîner le charbon dans le flux gazeux.The gases are extracted from chambers 1 and 2 by flues 24 located at the end of the chambers and on the floor so as to entrain the coal in the gas flow.

Les laveurs de gaz ressortissent du génie chimique classique.Gas washers are a product of classical chemical engineering.
