L'invention sera mieux comprise et d'autres buts, caractéristiques, détails et avantages de celle-ci apparaítront plus clairement dans la description explicative qui va suivre faite en référence aux dessins schématiques annexés donnés uniquement à titre d'exemple illustrant un mode de réalisation de l'invention et dans lesquels :The invention will be better understood and other purposes, features, details and benefits of it will appear more clearly in the description explanatory which will follow made with reference to the drawings annexed schematics given only as an example illustrating an embodiment of the invention and in which :

La figure 1 est une vue schématique illustrant l'agencement de répartition et d'injection des boues selon l'invention, dans une installation de four de co-incinération de boues et de déchets.FIG. 1 is a diagrammatic view illustrating the distribution and sludge injection arrangement according to the invention, in a co-incineration furnace installation sludge and waste.

La figure 2 est une vue en coupe de l'agencement de répartition et d'injection des boues selon l'invention, indiqué en 4 sur la figure 1.FIG. 2 is a sectional view of the arrangement of FIG. distribution and injection sludge according to the invention, indicated at 4 in FIG.

La figure 1 montre une installation de four de co-incinération de boues et de déchets tels que des ordures ménagères, qui est équipée d'un agencement de répartition et d'injection de boues dans le four, selon la présente invention. Les références 3, 1, 2 désignent respectivement la chambre de combustion du four, une trémie d'alimentation en déchets et une goulotte qui amène les déchets versés dans la trémie 1 dans la chambre de combustion 3. L'agencement de répartition et d'injection des boues indiqué en 4 est disposé de façon à pouvoir injecter les boues dans la goulotte. Cet agencement est montré plus en détail sur la figure 2.Figure 1 shows a co-incineration furnace installation sludge and garbage such as garbage housewives, which is equipped with a distribution arrangement and sludge injection into the furnace, according to this invention. References 3, 1, 2 designate respectively the furnace combustion chamber, a waste hopper and a chute that bring the waste poured into hopper 1 into the chamber 3. The distribution arrangement and the sludge injection indicated in 4 is arranged so that ability to inject sludge into the chute. This arrangement is shown in more detail in FIG.

Selon cette figure, l'agencement de répartition et d'injection des boues dans la goulotte 2 dont la chemise d'eau est indiquée en 5 comporte essentiellement un collecteur 7 dans lequel sont poussées les boues par une pompe non représentée et un certain nombre d'injecteurs des boues 8 qui sont montés sur le collecteur et dont seulement un est représenté.According to this figure, the distribution arrangement and injection of sludge in the chute 2 whose shirt of water is indicated in 5 essentially comprises a manifold 7 in which are pushed the sludge by a pump not shown and a number of injectors sludge 8 which is mounted on the collector and whose only one is represented.

Le collecteur 7 de section transversale circulaire dans l'exemple représenté est fixé à la goulotte 2 par l'intermédiaire d'une manchette tubulaire 9 réalisée en deux parties 10 et 11 respectivement solidaires du collecteur 7 et de la goulotte 2 et assemblées à l'aide des brides 12 et 13 aux extrémités en regard des deux parties de manchette. La partie de manchette 10 solidaire du collecteur 7 fait radialement saillie vers l'extérieur de celui-ci et est coaxiale à une fenêtre circulaire 15 pratiquée dans la paroi du collecteur.The collector 7 of circular cross section in the example shown is attached to the chute 2 by through a tubular sleeve 9 made of two parts 10 and 11 respectively integral with the manifold 7 and chute 2 and assembled using flanges 12 and 13 at the ends opposite the two parts of cuff. The part of 10 cuff solidarity the collector 7 is radially outwardly projecting of it and is coaxial to a circular window 15 practiced in the wall of the collector.

L'injecteur 8 est réalisé sous forme d'un corps tubulaire dont la partie arrière 17 traverse diamétralement le collecteur 7 et dont la partie avant 18 est coaxiale à la manchette 9 et s'ouvre en 19 dans la goulotte 2. En traversant diamétralement le collecteur 7, l'injecteur passe à travers la fenêtre 15 et à travers une autre fenêtre 21 également pratiquée dans la paroi cylindrique du collecteur 7, diamétralement opposée à la fenêtre 15. L'extrémité arrière 22 du corps tubulaire 17 de l'injecteur, qui fait radialement saillie du collecteur 7 vers l'extérieur est fermée par une bride pleine 23 qui porte sur sa face frontale extérieure une patte d'extraction 24. La partie en saillie 22 est coaxialement engagée dans une manchette de support 25 qui est fixée sur la face extérieure du collecteur 7 en entourant la fenêtre 21.The injector 8 is made in the form of a tubular body whose rear part 17 crosses diametrically the manifold 7 and whose front portion 18 is coaxial with the cuff 9 and opens in 19 in the chute 2. In traversing diametrically the manifold 7, the injector goes through window 15 and through another window 21 also made in the cylindrical wall of the collector 7, diametrically opposite the window 15. The rear end 22 of the tubular body 17 of the injector, which projects radially from the collector 7 towards the outside is closed by a full flange 23 which has a paw on its outer front 24. The protruding portion 22 is coaxially engaged in a support cuff 25 which is fixed on the outside of the collector 7 surrounding the window 21.

L'injecteur est fixé sur le collecteur 7 grâce à un dispositif à démontage rapide, réalisé dans l'exemple représenté sous forme d'un collier à démontage rapide 27 qui, dans sa position de fixation, maintient la bride pleine 23 dans une position appliquée contre la face frontale de la manchette 25. D'autre part, pour maintenir l'injecteur dans une position coaxiale correcte dans le collecteur et la manchette 9 de fixation du collecteur sur la goulotte 2 et assurer l'étanchéité entre l'injecteur et le collecteur 7, le corps cylindrique 17 de l'injecteur est muni d'une bague de guidage et d'étanchéité 29 qui est prévue au niveau de la fenêtre 15.The injector is attached to the collector 7 by means of a fast disassembly device, made in the example shown as a quick disassembly collar 27 which, in its fixing position, holds the flange full 23 in a position against the face front of the cuff 25. On the other hand, to maintain the injector in a correct coaxial position in the manifold and collector fixing sleeve 9 on the chute 2 and ensure the seal between the injector and the collector 7, the cylindrical body 17 of the injector is provided with a guide ring and sealing 29 which is provided at the window 15.

Selon la présente invention, la partie arrière 17 de l'injecteur 8, qui est engagée diamétralement dans le collecteur 7 est pourvue d'une ou plusieur fente ou lumière axiale 30 qui sert de tamis de filtre. Dans l'exemple représenté, la longueur de la fente 30 est quelque peu inférieure au diamètre du collecteur.According to the present invention, the rear part 17 of the injector 8, which is engaged diametrically in the manifold 7 is provided with one or more slots or axial lumen 30 which serves as a filter screen. In the example shown, the length of the slot 30 is somewhat smaller than the diameter of the collector.

La surface passante du filtre de chaque injecteur est importante. A titre d'exemple, pour un injecteur de diamètre de 30 mm dont la section est de 7 cm2, la surface peut être de 20 cm x 1,5 cm x 2 = 60 cm2, soit 8,5 fois la section de l'injecteur pour deux fentes. The passing surface of the filter of each injector is important. By way of example, for an injector with a diameter of 30 mm and a section of 7 cm 2 , the surface can be 20 cm × 1.5 cm × 2 = 60 cm 2 , or 8.5 times the cross-section. the injector for two slots.

Il ressort de la description qui précède, que chaque injecteur possède son propre élément filtrant formé par la (ou les) fente 30 et est facilement démontable en défaisant le collier à démontage rapide 27 et en le retirant ensuite du collecteur à l'aide de la patte 24.It follows from the foregoing description that each injector has its own filter element formed by the (or) slot 30 and is easily removable in undoing the quick release collar 27 and then withdrawing from the collector using the tab 24.

Etant donné que le poids de chaque injecteur est faible, par exemple de l'ordre de 5 kg, le démontage est aisé. Le volume de rétention des corps étrangers est grand puisque constitué par le collecteur qui mesure 200 mm de diamètre et est de 2 à 6 m de long.Since the weight of each injector is small, for example of the order of 5 kg, disassembly is easy. The foreign body retention volume is great since constituted by the collector which measures 200 mm in diameter and is 2 to 6 m long.
