Definitions

  • the invention relates to a shaft cooler for dry-quenching coke and other lumpy fuels with a vertical circular chamber formed from refractory bricks, which has an upper conical section with a central loading opening and underneath an essentially cylindrical section with a lower discharge opening, the inside wall of the cylindrical section of gas discharge openings are arranged along the circumference at a distance from one another, which open into an annular collecting duct running in the lining above the gas discharge openings.
  • the invention has for its object to design the lining in the upper region of a shaft cooler so that a substantial relief is achieved in the critical zone of the support wall below the ring collecting channel.
  • the inner layer which is separated from the outer layer by a narrow gap, is made to a lesser thickness than the outer layer.
  • the walls of the layers are designed step-like in such a way that they delimit a step gap consisting of horizontal and vertical sections.
  • the step height suitably corresponds to at least the height of a stone of the masonry of the layers.
  • the division of the masonry according to the invention in the conical and subsequent cylindrical section of the shaft cooler into two mutually independent sections gives the possibility of diverting the greater part of the total load onto the masonry lying outside the ring collecting duct and thus relieving the inner zone below the gas exhaust openings accordingly.
  • the load at the critical point can also be largely influenced by the fact that the inner layer of the masonry in the conical part is formed less strongly than the outer layer.
  • the use of two independent masonry layers has the further advantage that the layers can expand independently of one another.
  • the design of the masonry provided according to the invention enables the load to be reduced by up to about 50% compared to a one-piece masonry with otherwise the same properties at the critical zone of the lower supporting wall. This relief of the masonry and the possibility of independent expansion of the two layers lead to a significant extension of the life of such a shaft cooler.
  • the shaft cooler contains an essentially vertical circular chamber 1, the walls 2 of which are made of refractory bricks and which includes an upper pre-chamber 3 and below the actual extinguishing chamber 4.
  • the pre-chamber 3 contains an upper conical section 5 with a central loading opening 6.
  • gas discharge openings 7 are arranged along the circumference at a distance from one another in the inner wall and open into an annular collecting duct 8 which runs above the wall and which is connected to an outlet opening 9 leading to the outside.
  • a conical part 10 which merges into a discharge opening 11 for the quenched coke.
  • the dry gas is supplied on the one hand through a central feed pipe 12 and on the other hand through a pipe 13 in the lower one conical part 10, which is formed from two superimposed sections, between which a slot 14 is left open for the entry of the dry gas into the interior of the conical part.
  • Fig. 1 the foundation is indicated at 15, on which the wall 2 of the shaft cooler rests.
  • the masonry in the conical section and in the adjacent cylindrical section of the prechamber 3 consists of an outer layer 16 and an inner layer 17 that is independent of this.
  • the inner layer 17 extends from the loading opening 6 up to the gas discharge openings 7. It preferably has a lower thickness than the outer layer 16.
  • the inner layer 17 of the masonry merges into supporting walls 18 in the transition area between the pre-chamber 3 and the extinguishing chamber 4, which extend between the gas discharge openings 7 and the weight of the inner layer 17 onto the wall 2 surrounding the extinguishing chamber 4 transfer.
  • the lower end of the support walls 18 runs on a common conical surface that widens downward.
  • the support walls 18 extend up to the underside of the ring collecting channel 8.
  • the design of the two masonry layers 16 and 17 is more clearly emphasized in FIG. 2. As can be seen from this illustration, there is a narrow gap above the ring collecting duct 8 between the two masonry layers 16, 17, which is designed as a step gap 19.
  • the gradations result from the respective height of the individual layers of masonry one above the other. The smallest possible step height corresponds to the height of a stone in the masonry.
  • the width of the gap can be chosen to be the same or different in the horizontal and vertical directions. It is essential that there is a continuous gap along the entire length between the two layers and weight loads from the outer masonry layer 16 to the inner masonry layer 17 are thus avoided. In this way it is ensured that the weight of the outer masonry layer 16, which makes up the greater part of the total load, is only transferred to the masonry lying outside the ring collecting channel 8.
  • the support walls 18 located below the ring collecting channel 8 are only loaded by the weight of the inner masonry layer 17 which, in comparison with known designs, causes a correspondingly reduced pressure load due to the lower overall volume, so that overall a substantial relief of the support walls 18 is achieved.
  • the use of two mutually independent masonry sections in the area of the prechamber 3 has the advantage that different expansions are possible here.

1. Cuve de refroidissement pour l'extinction à sec du coke et d'autres combustibles en morceaux, comportant une chambre circulaire verticale constituée par des briques réfractaires et comprenant une région supérieure tronconique percée d'un orifice central de chargement, ainsi qu'une région sous-jacente sensiblement cylindrique et munie d'une ouverture inférieure de déversement, cuve dans laquelle des ouvertures d'évacuation des gaz, pratiquées dans la paroi interne de la région cylindrique et longeant la périphérie à distance les unes des autres, débouchent dans un canal collecteur annulaire s'étendant dans le chemisage, au-dessus desdites ouvertures d'évacuation des gaz, caractérisée par le fait que, dans la région tronconique (5), la maçonnerie est formée par une couche tronconique externe et par une couche tronconique interne immédiatement contiguë, mais indépendante ; et par le fait que la couche interne (16) se prolonge vers le bas par la maçonnerie délimitant extérieurement le canal collecteur annulaire (8), tandis que la couche interne (17) se prolonge par la maçonnerie délimitant intérieurement ledit canal collecteur annulaire (8).
2. Cuve de refroidissement selon la revendication 1, caractérisée par le fait que la couche interne (17) présente une épaisseur moindre que la couche externe (16).
3. Cuve de refroidissement selon la revendication 1 ou 2, caractérisée par le fait qu'un interstice étroit est réservé entre les couches (16, 17, respectivement).
4. Cuve de refroidissement selon la revendication 3, caractérisée par le fait que les parois mutuellement opposées des couches sont réalisées en forme de gradins, de telle sorte qu'elles délimitent un interstice étagé (19) comprenant des tronçons horizontaux et verticaux.
5. Cuve de refroidissement selon la revendication 4, caractérisée par le fait que la hauteur des gradins correspond au moins à la hauteur des briques de la maçonnerie formant les couches.
6. Cuve de refroidissement selon la revendication 5, caractérisée par le fait que les tronçons horizontaux de l'interstice étagé possèdent une plus grande largeur que les tronçons verticaux.
