Definitions

  • the invention relates to a device for supplying rinsing and de - graphitizing air into the heavy gas lines leading to the individual heating walls of coking ovens. in which the release of a comparatively small opening cross-section for the purge air and then the release of a larger opening cross-section for the de-graphitizing air is provided.
  • the purge air is used to remove the residual gas quantity still present in the line after the high-pressure gas supply has been shut off, while the subsequent supply of the de-graphitizing air is intended to burn off graphite deposits formed in the high-pressure gas line and in the high-pressure gas nozzles. It is necessary to adjust the amount of purge air precisely to avoid deflagration due to the formation of ignitable mixtures.
  • a box-shaped device which is provided with a flap, is attached to the heavy gas line or to the air supply pipe connected to it.
  • This flap is usually connected by means of a chain to a linkage which is longitudinally displaceable via an actuating device (hydraulic cylinder or the like).
  • an actuating device hydroaulic cylinder or the like.
  • the flap With a first movement of the linkage, the flap is raised by a precisely predetermined amount, thereby opening up the opening cross-section for the required amount of purge air.
  • the flap is then raised completely, so that the full cross section is available for the inflowing of the de-graphitizing air.
  • the flap is closed after the de-graphitization process has ended by the opposite movement of the linkage and by the weight of the flap.
  • the invention is therefore based on the object. to create a device that ensures that the purge air is always available in the same amount regardless of any changes in length of the linkage.
  • the invention proposes that two cross-sections which can be shut off with flaps are provided for the purge air and the de-graphitizing air and open in succession in an adjustable manner.
  • the first opening flap for the purge air acts with a interchangeable aperture together.
  • the two flaps themselves are expediently connected in a manner known per se via chains or with a linkage, the degraphing air flap opening with a time delay in relation to the flushing flap.
  • the measure according to the invention ensures that the flap for the purge air which is actuated first is opened substantially fully, with temperature-related deviations in the flap stroke being insignificant. Due to the available opening released by the flap, the purge air quantity determined by this opening cross section can in any case flow into the heavy gas line without any quantity deviations. The formation of ignitable mixtures with the consequence of deflagration can be effectively prevented in this way. By using an interchangeable panel, the required amount of purge air can be changed at any time if necessary.
  • Fig. 1 is the air auxiliary pipe. indicated by 2 the gas line. which is connected to the additional air pipe and initially leads upwards to the associated heating wall, not shown here.
  • a box-shaped device 3 is arranged at the lower end of the additional air pipe. which can be designed as a cast or welded construction. In the present case, this box-shaped device has two flaps 4 and 5, of which the flap 4 is provided for the purge air and the flap 5 for the de-graphitizing air.
  • Chains 6 and 7 act on the two flaps, which run over chain guide rollers 8 and 9 and are connected to a linkage 12 at 10 and 11, respectively. This linkage rests on support and guide rollers 13 and 14 and is longitudinally displaceable by means of an actuating device, not shown here.
  • the arrangement and guidance of the chains 6 and 7 are made in this way. that when the linkage 12 moves in the direction of arrow A, the flap 4 is first opened and, as a result of the longer chain, the flap 5 is only raised when the linkage moves further.
  • Fig. 2 From Fig. 2 it can be seen that the flap 4 closes a replaceable panel 15, the opening 16 is adjusted to the required amount of purge air.
  • the flap 4, like the flap 5, cooperates with a seal embedded in the box-shaped device 3.
  • the flaps are provided with additional weights 17.
