Definitions

  • the invention relates to a cooler for dry coke cooling, which has in its upper part a prechamber extending into the area below the exhaust line for the gaseous cooling medium.
  • cooler designs For coke dry 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 embedded in the masonry of the cooler lining.
  • the disadvantages of this embodiment can be seen primarily in the fact that a large number of complicated stone shapes are required for the lining of the ring channel in the radiator lining 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 prechamber as well as the upper part and the lower part of the cooler can lie on a common central axis in a manner known per se.
  • the upper part of the cooler can be arranged eccentrically with respect to the antechamber and the lower part of the cooler, the center axis of the upper part being offset in the direction of the exhaust nozzle.
  • the annular space 3 located between the prechamber 1 and the upper part 8 of the cooler is in relation to FIG the center axis of the cooler is arranged concentrically.
  • the prechamber 1 has a conical taper in the area of the discharge nozzle 2 for the gaseous cooling medium, as a result of which the free cross section of the annular space 3 is correspondingly enlarged. This is important because the hot gases rising from the lower part 4 of the cooler collect in the annular space 3 before they reach the discharge line 2 for the gaseous cooling medium via the discharge pipe 2.
  • the jacket 5 of the pre-chamber 1 is formed from refractory material and has on the outside in the lower part the webs 6, which also consist of refractory material.
  • the webs 6 have a double function: on the one hand, they serve to support the antechamber 1 and, on the other hand, they make the flow of the hot gases rising from the lower part 4 of the cooler more uniform, so that they can better cover the entire cross section of the Distribute annulus 3.
  • the sliding joint 9 is provided between the upper part 8 and the lower part 4 of the cooler and the sliding joint 10 is provided between the prechamber 1 and the upper part 8 of the cooler.
  • the cooler does not have the same outer diameter over the entire height. Rather, the outer diameter of the lower part 4 is adapted to the inner diameter of the upper part 8, so that when the cooler heats up, the lower part 4 can freely grow along the sliding joint 9 into the upper part 8.
  • the sliding joint 10 is also provided between the antechamber 1 and the upper part 8, the upper part 8 does not need to change its position to the same extent as the lower part 4. The situation is of course analogous even when cooling, if the lower part 4 and thus the antechamber 1 are also subjected to shrinkage.
  • the formation of the sliding joints can take place in the manner known from hot-water heater designs.
  • FIG. 2 largely coincides with the embodiment in FIG. 1, with the same reference numbers naturally having the same meaning.
  • the upper part 8 of the cooler is arranged eccentrically, with the central axis of the upper part 8 being offset somewhat in the direction of the exhaust pipe 2 relative to the central axis of the prechamber 1 and the lower part 4.
  • This eccentric arrangement of the upper part 8 increases the free cross section in the annular space 3 towards the discharge nozzle 2.
  • the construction in FIG. 2 shows a different embodiment of the webs 6 than in FIG. 1. In this case, the webs 6 are pulled further up and also lie on the radiator jacket 7. This embodiment of the webs 6 enables the prechamber 1 to be supported even better.
  • Fig. 3 finally shows a section along the line A-A 'in Fig. 2, but only one half of the section is shown due to the given symmetry.
  • This figure clearly shows the eccentric arrangement of the upper part 8 and the circular layout of both the cooler and the prechamber.
  • the reference numbers here also match those of the other figures.
  • the hatched areas in the illustrations each represent the parts that are made of refractory material. It has been shown that when using the construction according to the invention, about 30% of the previously required requirement for refractory material can be saved.
  • the arrangement of the sliding joints 9 and 10 according to the invention also greatly reduces the susceptibility of the cooler to repairs due to stress and expansion cracks in the refractory material. If, contrary to expectations, damage occurs to the refractory material, it can be repaired relatively easily and at a relatively low cost because of the relatively simple construction of the cooler and the fact that only a relatively small number of stone shapes are required for the radiator lining .
