Definitions

  • the invention relates to a coke oven operating device of a coke ejecting machine and / or Koksüberleitmaschine a coke oven having a plurality of juxtaposed coke oven, designed for collecting and removing Schlabberkoks in or out of the range of a master cast of the coke oven, with a at least one coke scoop having blade means, wherein Coke bucket in a Auffang ein for catching the Schlabberkokses and the frame cleaning residues is disposed below a furnace door of the coking chamber near the ground of the master gear.
  • the invention relates to a coke oven operating machine with a coke oven operating device of the aforementioned type.
  • Coke ovens consist of a plurality of disk-like coking chambers, which are arranged side by side in a long row. Following coking of coal, the coke is discharged from the furnace with a coke-blowing machine. The necessary opening and closing of the furnace doors on the side of the coke ejecting machine is automatically carried out by the coke ejecting machine. The coke pushed out of the furnace by the coke-blowing machine is directed into a coke-fire vehicle by the cake guide integrated on a coke-transfer machine. The required opening and closing of the furnace doors on the side of Koksüberleitmaschine is automatically carried out by the Koksüberleitmaschine.
  • JP-A-51 112805 and JP-A-62 04879 disclose devices for catching slack coke.
  • a disadvantage of the known coke oven operating devices of the type described above is that released from the collected with the coke bucket Schlabberkoks in the coke bucket Störs and pollutants as emissions that are not detected by the usually provided on the Koksausd Wegmaschine and / or Koksüberleitmaschine suction , In addition to dusts, these emissions include, in particular, vapor, gas or smoke emissions.
  • the coke bucket for extinguishing captured Schlabberkoks is at least partially filled with water that evaporates when collecting hot Schlabberkoks.
  • the extinguishing of Schlabberkokses is basically possible with and without water. Together with the vapor, in addition to particles, gaseous pollutants are discharged from the interior of the coke shovel into the surrounding area of the coke shovel.
  • the object of the present invention is to avoid the above disadvantages.
  • the aforementioned object is achieved in a coke oven operating device of the type described above in that at least one suction device is provided on and / or in the coke bucket for sucking released in the region of the coke bucket emissions according to claim 1.
  • the invention is based on the idea of directly detecting the emissions released in the region of the coke bucket, before it can essentially lead to a transfer of the emissions from the interior of the coke bucket into the environment.
  • the resulting emissions are substantially completely detected and can not enter the surrounding area.
  • the suction device is provided on a longitudinal side of the coke bucket, in particular on both longitudinal sides of the coke bucket.
  • the suction device extends over the entire longitudinal side of the coke bucket. It is sufficient in principle that the suction device extends only over a partial region of the longitudinal side, preferably over a front portion of the longitudinal side.
  • a suction device is provided at the front of the coke bucket or that the suction device extends over the two longitudinal sides and the front of the coke bucket.
  • the suction device or its suction opening is provided in the area of the upper edge of the bucket or in the region of the upper edge of a side wall of the coke bucket the suction device is connected.
  • the side wall of the coke bucket having a downwardly angled or rounded edge, which facilitates the detection of emissions released in the interior of the coke bucket. This also ensures that it comes essentially to the exhaust of the released inside the coke shovel emissions and that the proportion of the also detected air flow from the environment is kept as low as possible.
  • At least one suction opening of the suction device extends over the entire length of the side wall connected to the suction device. This ensures a uniform detection of emissions over the entire longitudinal side of the side wall.
  • the suction opening of the suction device is directed into the interior of the coke bucket, which further promotes the detection of emissions released inside the coke bucket.
  • the suction device may preferably be formed as a vortex hood in order to ensure the most uniform possible detection on the entire blade length and a high suction power with a small size of the suction.
  • the necessary acquisition volume flow must be determined by the method of volume budgeting.
  • an inner guide surface of the suction device can be formed by a preferably inclined sidewall of the coke shovel.
  • the guide surface is intended to direct the emissions released in the interior of the coke bucket in the direction of the suction opening of the suction device.
  • the side wall of the coke bucket and the swirl hood are integrally formed, wherein the upper edge of the side wall of the shape of a swirl hood can be bent inwardly accordingly. If the guide surface and the vortex hood are integrally formed from a side wall of the coke bucket, this contributes to a simple design of the coke oven operating device according to the invention.
  • the invention also allows for, if necessary, that a suction device connected to a side wall or a front wall of the coke bucket, for example screwed or welded, which allows a later retrofitting of the coke bucket of a coke oven operation device with a suction device.
  • the cross section of the vortex hood may be formed partially cylindrical or polygonal, wherein in both forms, an end portion of the vortex hood may be retracted to the central axis of the vortex hood to achieve a desired constriction of the flow before entering the region of the suction opening.
  • a vortex hood may have at least two suction points.
  • the drain pipes are connected to a suction and fluidly represent each a double sink, wherein the drain pipes in such a spaced are arranged that results in each case a swirl flow between adjacent drain pipes. This ensures a particularly high extraction capacity with low energy consumption of the extraction system.
  • a value for the safety factor ⁇ of 1.1 to 3.0, preferably of about 1.5, could be determined.
  • the ratio of detection volumetric flow to emission volume flow at the level of the suction device is consequently between 1.1 and 3.0, preferably approximately 1.5.
  • the coke oven operating device can be provided on the coke ejecting machine and / or on the coke transfer machine.
  • the acquisition volume flow should preferably be between 3,000 m 3 / h and 5,000 m 3 / h be as long as the coke oven is provided on the coke pushing machine.
  • the detection volumetric flow can be between 2,000 m 3 / h and 4,000 / hm 3 , since as a rule the emission volume flow on the side of the coke transfer machine is lower than on the side of the coke extruder of the coke oven.
  • a detection volume flow on the side of Koksausdschreibmaschine of about 4,200 m 3 / h and on the side of Koksüberleitmaschine of about 3,000 m 3 / h could be determined.
  • a coke oven operating device 1 is designed for picking up and removing slag coke in or out of the region of a master run 2 of a coke blowing machine not shown in detail of a coke oven having a plurality of adjacent coking chambers 3.
  • the coke oven operating device 1 has a blade device 4 with at least one coke bucket 5, wherein the coke bucket 5 in Fig. 1 is arranged in a Auffang ein for catching Schlabberkoks below a door opening of the coking chamber 3 near the ground of the master gear 2.
  • a chute 7 is provided, via the manner not shown from the interior of the coking chamber 3 during the Ausd Wegvorgang escaping Schlabberkoks in the coke bucket 5 of the blade device 4 is transferred.
  • the coke oven operating device 1 also has a transfer device 8 for transferring the slag coke received by the coke bucket 5 into a collecting container 9.
  • the contents of the coke bucket 5 can also be transferred to a bunker or on the side of Koksüberleitmaschine in a Kokskuchenfiihrungs uncomfortable.
  • the transfer device 8 has an inclined further slide 10, which is designed to be movable back and forth between the collecting container 9 and the blade device 4.
  • Fig. 2 the vane device 4 is shown with the coke bucket 5 in a discharge position or basic position.
  • the emptying takes place via the chute 10. Further, it is necessary for transferring the coke bucket 5 from the Auffang ein to the emptying position to raise the coke bucket 5 from the bottom portion of the master gear 2 and to pivot around the pivot axis 11 for emptying.
  • the extinguishing of the Schlabberkokses is possible with and without water.
