Description

L'invention concerne une installation pour brûler de vieilles couches de peinture d'objets métalliques, comme les radiateurs de chauffage et les crochets de suspension, et pour l'incinération de déchets.The invention relates to an installation for burning old paint layers of metallic objects, such as heating radiators and suspension hooks, and for incinerating waste.

Selon la principale caractéristique de l'invention, cette installation se compose essentiellement d'une chambre de combustion, d'un brûleur raccordé à cette chambre de combustion avec des ouvertures d'aération destiné à chauffer l'air et les gaz de fumée dans la chambre de combustion, d'un four qui se ferme et dans lequel les objets à brûler ou les déchets à incinérer sont logés, d'un ventilateur dont le conduit d'aspiration est raccor­dé à la chambre de combustion et le conduit de refoule­ment au four et destiné à faire circuler les gaz de fumée à travers l'installation, d'un canalisation d'aspiration prévue entre le four et la chambre de combustion et destinée à évacuer les gaz de fumée du four et d'une che­minée d'évacuation raccordée à la chambre de combustion et destinée à évacuer les gaz de fumée développés en surnombre.According to the main characteristic of the invention, this installation essentially consists of a combustion chamber, of a burner connected to this combustion chamber with ventilation openings intended to heat the air and the flue gases in the combustion chamber, an oven which closes and in which the objects to be burned or the waste to be incinerated are housed, a fan, the suction duct of which is connected to the combustion chamber and the discharge duct of the furnace and intended to circulate the smoke gases through the installation, a suction pipe provided between the oven and the combustion chamber and intended to evacuate the smoke gases from the oven and a connected exhaust chimney to the combustion chamber and intended to evacuate the excess smoke gases developed.

Du fait que la majeure partie de l'air chauffé et les gaz de fumée développés sont conduits dans un circuit pratiquement fermé et circulent plusieurs fois à travers la chambre de combustion, peu de chaleur se perd et l'on obtient une bonne combustion postérieure, de sorte qu'il reste peu de résidus de cendres. En même temps, la con­sommation de combustible est, de ce fait, maintenue faible, il ne se développe que peu de fumée et une pe­tite quantité seulement de gaz de fumée est évacuée à l'extérieur. Cette installation est donc favorable à l'environnement et comporte peu de danger pour le per­sonnel de service.Because most of the heated air and developed smoke gases are conducted in a practically closed circuit and circulate several times through the combustion chamber, little heat is lost and good posterior combustion is obtained, so that little residue of ash remains. At the same time, fuel consumption is therefore kept low, little smoke is produced and only a small amount of smoke gas is discharged to the outside. This installation is therefore environmentally friendly and poses little danger to service personnel.

A titre d'exemple suit ci-après une description détaillée d'une forme d'exécution choisie, mais nullement limitée de l'installation conforme à l'invention. Cette descrip­tion renvoie au dessin ci-annexé, dans lequel

  • la fig. 1 représente une coupe verticale de l'installa­tion;
  • la fig. 2 représente une coupe transversale de l'in­stallation suivant la ligne II-II de la fig. 1.
By way of example below follows a detailed description of a chosen embodiment, but in no way limited to the installation according to the invention. This description refers to the attached drawing, in which
  • fig. 1 represents a vertical section of the installation;
  • fig. 2 shows a cross section of the installation along line II-II of FIG. 1.

Dans ces figures on remarque la chambre de combustion cylindrique 1, qui est ouverte au haut bout et autour de laquelle un manteau cylindrique 2 est placé à une cer­taine distance, par quoi un espace de réchauffement 3 est formé entre la chambre de combustion et le manteau. A son haut bout, le manteau 2 est fermé par un couvercle 4 pourvu en son centre d'une ouverture 5, au-dessus de laquelle est monté un brûleur 6 à ouvertures d'aération 7 sur le couvercle 4. Le bord supérieur de la chambre de combustion 1 est situé plus bas que le couvercle 4, de sorte que contre le brûleur il se forme une ouverture annulaire 8 entre la chambre de combustion 1 et l'espace de réchauffement 3. Sur le bord supérieur de la chambre de combustion 1 sont fixés plusieurs boulons 9, par lesquels la chambre de combustion 1 est attachée au couvercle 4. L'extrémité inférieure de la chambre de com­bustion 1 débouche en se rétrécissant dans un espace 10, dans lequel est prévue une ouverture 11 à laquelle est raccordé le conduit d'aspiration 12 d'in ventilateur 13, qui est actionné rotativement par un moteur 14. Le con­duit de refoulement 15 du ventilateur 13 est raccordé à une ouverture 16 d'un four 17 entouré d'un revêtement isolant 18 et dans lequel à quelque distance du fond du four est placée une plaque portante 19 pourvue d'ouver­tures 20, sur laquelle plaque portante les objets à brûler ou les déchets à incinérer sont placés. Ces objets ou déchets sont introduits par une porte ou un couvercle (non représentés) dans le four. Au haut bout, le four 17 possède une ouverture 21 à laquelle est raccordée une canalisation d'aspiration 22, qui est également raccordée à la partie inférieure de l'espace de réchauffement 3 pourvu d'une cheminée d'évacuation 23.In these figures we note the cylindrical combustion chamber 1, which is open at the top and around which a cylindrical mantle 2 is placed at a certain distance, whereby a heating space 3 is formed between the combustion chamber and the mantle . At its top, the mantle 2 is closed by a cover 4 provided in its center with an opening 5, above which is mounted a burner 6 with ventilation openings 7 on the cover 4. The upper edge of the combustion chamber 1 is located lower than the cover 4, so that against the burner an annular opening 8 is formed between the combustion chamber 1 and the heating space 3. On the upper edge of the combustion chamber 1 are fixed several bolts 9, by which the combustion chamber 1 is attached to the cover 4. The lower end of the combustion chamber 1 opens out by narrowing in a space 10, in which an opening 11 is provided to which the suction duct 12 of the fan 13 is connected, which is rotated by a motor 14. The discharge duct 15 of the fan 13 is connected to an opening 16 of an oven 17 surrounded by an insulating coating 18 and in which at some distance from the bottom of the oven is placed a supporting plate 19 provided with openings 20, on which bearing plate the objects to be burned or the waste to be incinerated are placed. These objects or waste are introduced through a door or a cover (not shown) into the oven. At the top, the oven 17 has an opening 21 to which a suction pipe 22 is connected, which is also connected to the lower part of the heating space 3 provided with an exhaust chimney 23.

Lorsque le brûleur 6 et le ventilateur 13 sont mis en service, l'air est chauffé dans la chambre de combustion 1 à une température d'à peu près 1400°C et cet air chauffé est soufflé dans le four 17 en passant par l'ouverture 11 de la chambre de combustion 1, par le ventilateur 13 et par l'ouverture 16, par quoi la peinture des objets pla­cés sur la plaque portante 19 est brûlée ou les déchets mis sur la plaque portante 19 sont consumés. Les gaz de fumée développés à cette occasion sont détournés à envi­ron 430°C ou éventuellement davantage par l'ouverture 21 du four et par la canalisation d'aspiration 22 dans l'espace de réchauffement 3 et sont conduits vers le haut le long de la paroi chauffée au rouge de la chambre de combustion 1, par suite de quoi la température des gaz de fumée évacués monte sensiblement et ces gaz sont aspirés via l'ouverture annulaire 8 dans la chambre de combustion 1, où ils sont mélangés à l'air frais chauffé par le brûleur et portés à près de 1400°C. Les gaz chauffés s'ajoutant pendant cette circulation pratique­ment fermée ou surabondants trouvent un échappement le long de la cheminée d'évacuation 23 montée sur l'espace de réchauffement 3. Les rares résidus de combustion qui restent dans l'installation sont receuillis dans le four 17 sous la plaque portante 19, d'où ils peuvent être évacués sans peine.When the burner 6 and the fan 13 are put into operation, the air is heated in the combustion chamber 1 to a temperature of approximately 1400 ° C. and this heated air is blown into the oven 17 passing through the opening 11 of the combustion chamber 1, by the fan 13 and by the opening 16, whereby the paint of the objects placed on the supporting plate 19 is burnt or the waste put on the supporting plate 19 is consumed. The smoke gases developed on this occasion are diverted at about 430 ° C or possibly more by the opening 21 of the oven and by the suction line 22 in the heating space 3 and are led upwards along the red-hot wall of the combustion chamber 1, as a result of which the temperature of the evacuated smoke gases rises substantially and these gases are sucked through the annular opening 8 into the combustion chamber 1, where they are mixed with the air fresh heated by the burner and brought to almost 1400 ° C. Gas heated, added during this practically closed circulation or superabundant, find an exhaust along the exhaust chimney 23 mounted on the heating space 3. The rare combustion residues which remain in the installation are collected in the furnace 17 under the supporting plate 19, from where they can be evacuated without difficulty.

Il va de soi que l'installation peut avoir n'importe quelles forme et dimensions, que certaines des parties constituantes décrites ci-dessus pourraient être rem­placées par d'autres qui visent au même but et que l'installation pourrait être pourvue de moyens supplé­mentaires qui en amélioreraient le fonctionnement.It goes without saying that the installation can have any shape and size, that some of the constituent parts described above could be replaced by others which aim at the same goal and that the installation could be provided with additional means. which would improve its functioning.
