Definitions

  • the invention relates to a cooler for coke dry cooling, which has an annular installation in its upper part in the area of the exhaust line for the gaseous cooling medium.
  • cooler designs For dry coke cooling, cooler designs have been known for a long time, in which the gaseous cooling medium is drawn off from the upper part of the cooler via an annular channel arranged in the masonry of the cooler lining.
  • the disadvantages of this embodiment can be seen above all in the fact that a large number of complicated stone shapes are required for the lining of the ring channel and that overall an extraordinarily large amount of refractory lining material is required for such an embodiment.
  • damage to the refractory lining almost always occurred, which in this embodiment can be repaired hardly or only with great difficulty and with a considerable expenditure of time and material .
  • the ring-shaped installation together with the rest of the radiator lining is made entirely of fireproof masonry. This means that the disadvantages described above also occur here, albeit in a weakened form.
  • a one-piece device for cooling or preheating coarse-grained bulk material which consists of a steel jacket, which is either provided with a lining on its inside, or in which the outside is equipped with a cooling system.
  • a gas collecting space is provided in the upper part of the device, which is separated from the actual cooling chamber by a wall provided with gas passage openings.
  • the bulk material is fed into the device by means of a sleeve-like cylindrical piece of pipe which connects the top surface of the device to the wall provided with gas passage openings.
  • US Pat. No. 4,141,795 shows a device for dry coke cooling in which, based on the embodiment described above, the gaseous cooling medium is drawn off via an annular channel embedded in the cooler wall lining.
  • the patent specification does not provide any details as to how the radiator wall lining is to be designed.
  • DE-C-492 943 describes a coke cooling system which, with a one-piece overall construction, includes a cooling chamber which is formed by cooling pipes.
  • a cooling chamber which is formed by cooling pipes.
  • the hot coke is charged via an obviously tubular connection piece into the inner chamber formed from cooling pipes, which is arranged within a one-piece, outer enclosure.
  • the annular installation has a conical shape instead of the previously customary cylindrical shape, because this creates a relatively large annular space between the inside of the cooler and the outside of the annular installation, which already has a relatively good shape due to its conical shape Distribution of the gases deviating from the coke over the entire circumference.
  • suitable internals can also be provided in the annulus to equalize and / or throttle the gas flow. This can be done, for example, in a particularly simple form in that a support ring is fastened to the outside of the ring-shaped installation, while the opposite refractory radiator lining has a corresponding recess, so that the installations can rest loosely on the support ring and the opposite recess.
  • These internals can also consist of a heat-resistant metallic material. But it can also be fireproof shaped stones such. B. so-called slide stones come to use.
  • the connecting piece for the exhaust line for the gaseous cooling medium has a round cross section.
  • cooler shows as a longitudinal section only that part of the cooler which is necessary for explaining the design features essential to the invention.
  • the upper end of the cooler with the feed device for the coke to be cooled and the lower end of the cooler with the discharge device for the cooled coke and the gas inlet nozzle are not shown.
  • it is assumed that it is a cooler in which, in a manner known per se, the coke to be cooled, which is fed in from above, is treated with a gaseous cooling medium rising in countercurrent from the bottom up.
  • the invention is not tied to any specific embodiment.
  • the ring-shaped installation 1 has a conical shape.
  • the cone jacket 2 consists of a heat-resistant metallic material, for. B. heat-resistant steel.
  • the wear and heat protection layer 3 is attached to the inside of the cone jacket 2. This can consist of fireproof masonry or fireproof spray or ramming compound.
  • This protective layer it is also possible to protect this protective layer by so-called. Apply flame spray.
  • B also consist of two superimposed layers with different material properties.
  • the top layer can be distinguished by a particularly high wear resistance, while the layer underneath has a particularly good insulation capacity.
  • the ring-shaped installation 1 is suspended via the ring-shaped bracket 4, which is fastened to the outer radiator jacket 6 by the anchors 5. Between the upper edge of the conical jacket 2 or the bracket 4 and the radiator jacket 6 there is still the gas-tight seal 16, which also provides a certain amount of heat insulation to the radiator jacket 6.
  • the cooler in the present case is not provided with a continuous outer cooler jacket 6, but consists of an upper part 7 and a lower part 8, which are connected to one another via the sliding joint 9.
  • the inner diameter of the upper part 7 is adapted to the outer diameter of the lower part 8, so that it can grow freely into the upper part 7 when the cooler is heated, without the latter having to change its position to the appropriate extent.
  • the conditions are also the same when cooling, when the lower part 8 is subjected to shrinkage.
  • the support ring 10 is attached to the outside of the cone jacket 2, while the opposite radiator lining 11 has a recess 12 at the height of the support ring 10.
  • these can consist, for example, of so-called slide stones or similar refractory shaped stones which are simply placed loosely on the support ring 10 and the recess 12.
  • the internals 13 are evenly distributed over the entire cross section of the annular space between the cone jacket 2 and the radiator lining 11.
  • connection stub 15 preferably has a round cross section.
  • the shaded areas in the figure each represent the radiator lining. It has been shown that using the construction according to the invention can save more than 50% of the previously required requirement for refractory material.
  • the arrangement of the sliding joint 9 according to the invention greatly reduces the susceptibility to repairs of the radiator due to stress or expansion cracks in the refractory material of the radiator lining. If, contrary to expectations, damage should occur, it can be repaired relatively easily and at a relatively low cost because of the simplicity of the proposed construction and its good accessibility and due to the fact that only a small number of stone molds are required for the radiator lining.
