Definitions

  • the invention relates to a suction hood attached to the coke cake carriage for the emissions occurring when the coke is discharged from a coke oven chamber.
  • a hood construction is known in which the hood at least partially covers the receiving surface of the coke loading and unloading carriage for the glowing coke.
  • the hood is firmly connected to the coke loading and unloading car and can be moved with it to the extinguishing tower, which requires a complex and therefore expensive and uneconomical construction.
  • the invention is therefore based on the object of creating a suction hood construction, on the one hand an unhindered escape of the emissions occurring when the coke is discharged from a coke oven chamber into the atmosphere as far as possible and which, on the other hand, is characterized by the simplest and therefore most economical construction.
  • a suction hood attached to the coke cake carriage which according to the invention is characterized in that it is composed of two or more chimneys and has an overall suction cross section which is larger than the base area of the coke loading and unloading car used, the individual chimneys have a taper towards the associated chimneys.
  • the use of the construction according to the invention ensures that the coke in the coke loading and unloading car is always below a suction cross section of a chimney during the entire pressing process, so that no dust-laden gases enter the atmosphere even when the coke loading and unloading car is being moved can.
  • the number of chimneys from which the suction hood according to the invention is made up depends, of course, on the practical circumstances, in particular, of course, on the amount of dust-laden gases and the length of the route which the coke loading and unloading car has to travel through during the pressing process. In any case, it must be ensured that this distance from the start to the end point is covered by the suction cross-sections of the individual chimneys.
  • suction hood according to the invention is particularly advantageous in the case of conventional long and flat coke loading and unloading vehicles with an inclined bottom.
  • the suction hood shown in Fig. 1 is composed of the two chimneys 1 and 2, which are connected to one another via the intermediate piece 3. Under the chimneys 1 and 2, the coke loading and fire engine 4 along. This assumes position A with its front head end at the start of the printing process, while the front head end is in position B at the end of the printing process.
  • the coke oven chamber to be pressed bears the reference number 5.
  • position A the dust-laden gases are essentially extracted only through the first chimney 1.
  • the coke loading and unloading carriage 4 is then moved more and more towards B, so that the dust-laden gases are also increasingly extracted through the chimney 2, as indicated by the arrows in FIG. 1 becomes.
  • the position of the coke loading and unloading carriage 4 at the beginning of the pressing process is marked in the figure by the broken lines, while the position at the end of the pressing process is marked by the solid lines. It can be seen from this that the entire base area of the coke loading and unloading carriage 4, which is covered with glowing coke, is always below the suction cross section of the chimneys 1 and / or 2 during the entire pressing process. Escape of the dust-laden gases into the atmosphere is practically impossible.
  • FIG. 1 also shows that the chimneys 1 and 2 have a taper towards the associated chimneys 6.
  • This taper in the chimney 2 is larger than in the chimney 1. This takes into account the fact that with increasing distance from the coke oven chamber 5 the amount of dust-laden gases rising from the glowing coke decreases, which is why the suction effect in the chimney 2 must be greater than in the Chimney 1.
  • a spraying and separating device 7 is provided, through which the dusts rising with the hot gases are separated.
  • the chimneys 6 have a diffuser-like extension 8 at their upper end to improve the suction effect.
  • Fig. 2 shows a section along the line II - II 'through the suction hood shown in Fig. 1.
