Definitions

  • the invention relates to a coke quenching device according to the preamble of patent claim 1.
  • Coke quenchers are known.
  • DE-PS 8T3 686 a device for deleting
  • this device When using modern coke ovens, this device must be moved during the pressing-out process to take up the red-hot coke and must have a length of about 14 to 24 m. This makes dust removal very difficult, since the detection hoods 5 are designed to be very large and contain considerable amounts. gases containing dust must be extracted. Also, the packed bed of coke in the quenching car and characterized 'Hin mat ⁇ the flow of water vapor is very uneven, resulting in 0 considerable differences in the coke temperature and in the Koksfeuchte because of the very slanted bottom. Finally, the device is not suitable for using the gases released during the extinguishing, such as water vapor, for further use. b
  • OMPI DE-PS 23 20057 discloses a method and a device for extinguishing a heated bulk material, in particular coke.
  • the coke to be cooled lies in a container on a permeable floor.
  • the container is closed with a lid with outlet openings for the extinguishing water.
  • the extinguishing container • 0 rests on a box, the grate bar of which consists.
  • the upper part forms the permeable container bottom. At least one of the side walls of the box can be pivoted outwards.
  • the grate must support the weight of the coke fill, which can reach 30 t;
  • the grate is heated by the glowing coke, which has temperatures of 1000 to 1100 C;
  • the grate is subjected to the above-mentioned stresses periodically, since the extinguishing cycle is repeated continuously. This causes signs of aging to appear in the rust material earlier than with constant long-term stresses.
  • the side wall pivotally attached to the box below the known extinguishing container naturally has surfaces which have to be sealed separately and which can lead to leakages at high steam pressures.
  • DE-OS 29 29 385 also specifies an extinguishing container in which heated coke lies on a grate and is treated with extinguishing liquid from above. The steam formed emerges from the side of the extinguishing container at the bottom.
  • US Pat. No. 2,250,262 shows a laterally unloadable container with a saddle bottom.
  • the aim of the floor arrangement which is inclined on two sides, is intended on the one hand the impact and thus the breaking of bulk material, e.g. of coke, if it falls into the container from a greater height.
  • the slope of the bottom should also accelerate the emptying of the container.
  • the publication does not refer to the extinguishing of coke.
  • the invention is based on the object of specifying a coke extinguishing device in which, on the one hand, the gases formed during the extinguishing, e.g. Water vapor flows through the coke fill evenly without creating areas with very different temperatures. These gases should also be able to be collected and cleaned for further use after they have passed through the coke bed.
  • the gases formed during the extinguishing e.g. Water vapor flows through the coke fill evenly without creating areas with very different temperatures.
  • These gases should also be able to be collected and cleaned for further use after they have passed through the coke bed.
  • the parts of the device ' should be designed so that they the mechanical, thermal and chemical loads, for example the loads mentioned above under _ a) to f), can withstand sufficient even after numerous extinguishing cycles, ie have a long service life and can be renewed easily and quickly if necessary.
  • the facility should also, especially at a
  • the device according to the invention in particular the retaining elements in the discharge lines for the gases produced during the extinguishing, have a particularly long service life because at least the mechanical and thermal loads on the retaining elements are significantly reduced.
  • the weight of the coke bed does not rest on the retaining element.
  • This can also be arranged in such a way that it does not come into direct contact with the very hot, not yet extinguished coke.
  • the arrangement of the retention members in the discharge lines for the gases produced during extinguishing enables them to be replaced quickly without long interruptions in operation.
  • the height of the coke bed in this container can extend further downward, thus increasing the usable volume.
  • the. Gases can be obtained from the extinguishing container at an additional height of approximately 600 mm for the coke fill in the container. This is particularly important when using the extinguishing container in the form of a single-point container car and when receiving coke to be extinguished from oven batteries of various, in particular older, designs. In addition to the better possibilities for using the device, there are also lower construction costs for the extinguishing container.
  • the bottom of the extinguishing container is designed as a closed deflecting bottom.
  • This shape of the base is particularly well adapted to the streamlines of the extinguishing medium in the coke bed and ensures a uniform cooling of the coke.
  • the deflecting base is perforated and combined with an underlying gas collection space, which is connected via partial lines to the leads leading to gas cleaners. -This ensures that the directly on the The extinguishing medium flows well around the coke layer lying on the deflection floor and is thus cooled uniformly.
  • the retention members in the discharge lines of the extinguishing container are preferably adjustable to change the clear cross section of the discharge lines. This is favorable for the optimization of the extinguishing process, because it means the ratio of the partial flows of the extinguishing medium via the retaining element and via the perforated base, depending on e.g. the type of coke, its temperature and its bulk density can be set individually.
  • the outlet ends are for accelerated discharge of the extinguishing medium from the gas collection space under the perforated baffle. of the associated sub-lines are arranged within the derivatives in which the retaining members are provided.
  • the outlet ends of the partial lines can be designed as injector nozzles.
  • the clear cross section of the discharge lines which have the retaining members, is reduced in the area of the injector nozzles. This increases the speed of the extinguishing medium flowing around the injector nozzles. The result is a negative pressure in the area around the injector nozzles and an increased suction of gases from these nozzles.
  • the flow conditions in the extinguishing container lead to a particularly uniform cooling of the coke when the deflecting base is at its highest in the central region of the extinguishing container and from there is sloping symmetrically in the direction of the outlet openings, in the area of which the retaining elements lie .
  • the retaining members are preferably designed as grids. It is advantageous if the main surface of the grate at the beginning or inside the discharge line for the extinguishing medium is arranged perpendicular to the longitudinal direction of this discharge line. This results in the smallest possible dimensions for the grate.
  • a device the container base of which is designed as a deflecting base, and in each of which a grate as a retaining element lies in the plane of the nearest wall, the extinguishing container.
  • This arrangement of the retaining member is relatively simple to manufacture.
  • the coke When the glowing coke is poured into the container, the coke is deflected inwards by the deflection devices, so that the grids are not touched by the falling coke.
  • Path length can be set, which is covered by the extinguishing water in the coke bed. For example, more extinguishing water can be applied to the surface of the coke bed in those areas, 5 of which the path of the extinguishing water through the coke bed is longer than from other areas.
