Definitions

  • the invention relates to a method for extracting emissions when coke is being pressed out of coking furnace chambers via a hood which can be moved on the coke side and is connected to a stationary extraction system, the emissions both via the discharge point of the red-hot coke and over the part of the fire-fighting vehicle which is already filled with coke be sucked off.
  • the invention also includes a device for carrying out the method.
  • DE-A-2 842 655 describes a hood for collecting emissions rising in the area of a coke oven battery, in particular when coke is being pressed out, which are discharged via a blower or by means of a collecting line, the hood at least in its upper inner area being a filter for separation of the solid components contained in the rising emissions.
  • the filter is attached to a support structure at a distance from the inner wall of the hood.
  • the supporting structure can have walls made of perforated plates which are covered by the filter cloth on the surface pointing in the direction of the fire-fighting vehicle.
  • relatively large amounts of gas must be drawn off through the filter to prevent emissions.
  • the object of the invention is to improve the method for extracting emissions when coke is pressed out by further reducing the amount of extraction required and to propose a suitable device for carrying out the method.
  • the ratio of the gases drawn off at the outer lower edge to the gases drawn off above the coke bed should be between 1 to 1 and approximately 5 to 1.
  • a device consisting of a high part arranged during the pushing-out process above the discharge point of the coke and a low part of the hood adjoining it in the direction of travel of the fire-fighting vehicle, and both on the upper and the lower part of the Hood suction lines are connected, which is characterized in that the hood is double-walled and the outer and inner hood have an adjustable distance from each other at the lower edge for targeted extraction of emissions.
  • the inlet cross-section of the emission gases at the bottom the amount of gases removed can be set to an optimal value.
  • the criterion for this setting is that the extraction is as low as possible so that some air is always drawn in from the outside, but emission gases can never penetrate from the inside out.
  • the lower edges of the inner hood In order to improve the flow properties, it has proven to be advantageous for the lower edges of the inner hood to spring back in relation to the edge of the outer hood. Jumping back essentially means that the lower edge of the inner hood is arranged higher than the outer edge. In addition, it has proven to be advantageous to fold the lower edges of the inner hood inwards.
  • the new construction according to the invention ensures that the amount of exhaust gas required can be significantly reduced and that in particular, the air is directed to the place where it is required for perfect extraction to prevent dust from escaping. This should result in lower total investments and significantly lower energy costs for the extraction fans.
  • Fig. 1 both the high part 1 and the low part 2 of the hood is shown. Inside or below the outer hood 3, the inner hood 4 is shown, which is attached to this outer hood at a distance.
  • the fire truck 18 is shown in two different positions below the hood. At the beginning of the squeezing process, the front part of the fire truck is located under the upper part of the hood 1, the fire truck front edge being arranged at 8. During the coke extraction, the fire truck travels below the hood under the low part of the hood until the front edge of the fire truck is located at 9 and the end of the fire truck at 10 after the coke injection process has ended.
  • the greater part of the gases is sucked out via the lower outer annular gap 13 between the outer and inner hood, and the gases that rise above the hot coke bed due to their buoyancy emerge and hit through the adjustable slits in the apex area of the inner hood there together with the gases drawn off at the outer annular gap 13.
  • the ratio of the suction quantity of these two gas flows to one another is regulated with the aid of the calibration plates 16 and 17.
  • the gases drawn off at the lower part of the hood are automatically regulated by means of the throttle valve 5 and pass via the suction line 6 to the transfer piece 7, where they are combined with the emission gases which have been drawn off under the high part of the hood.
  • the gases are expediently fed into the stationary suction line via a belt loop carriage. 1 that the lower edge 11 of the inner hood 4 is arranged higher than the lower edge 12 of the outer hood. Finally, the partition 15 between the low and high part of the hood is shown. On both sides of this partition, which extends transversely to the direction of travel of the fire truck, a suction gap 14 is formed between the partition 15 and the inner hood.
