Definitions

  • the invention relates to a coking oven with a plurality of horizontal coking chambers closed on the top with an oven ceiling, with closable filling holes provided in the oven ceiling for each of the coking chambers and with rails arranged on the oven ceiling and with a coke oven filling wagon movable on the rails, the coke oven filling wagon is provided with filling pipes which can be lowered into the filling holes of the respective coking chamber and a collecting device for the filling gases generated during filling, the filling gases collected with the collecting device being able to be supplied to a filling gas cleaning station arranged on or on the coking oven, with a stationary station connected to the filling gas cleaning unit on the furnace ceiling Filling gas manifold is provided and the collecting device on the coke oven filling wagon can be connected to the filling gas manifold.
  • the invention is based on the object of designing and developing the known coking oven in such a way that the temperature of the filling gases can be reduced in a simple manner to such an extent that dry cleaning methods can be used in the filling gas cleaning
  • the coking furnace according to the invention in which the above-mentioned object is achieved, is characterized in that the collecting device and / or the filling gas manifold is provided with bypass valves for introducing fresh air.
  • Bypass valves of the type mentioned allow fresh air to be admixed to the captured and extracted filling gases to a certain extent, so that the temperature of the filling gases is reduced.
  • the temperature of the filling gases can be reduced to such an extent that «dry» cleaning processes can be used in the filling gas cleaning without further notice. In such a case, tissue filters or the like can easily be used.
  • further valves or valve-like devices can be provided, such as throttle valves or the like, so that the mixed gas quantities and the temperatures reached or attainable can be set precisely.
  • the extracted filling gases can be diluted to such an extent that post-combustion is not necessary for environmental reasons. Nevertheless, it is of course readily possible to provide the collecting device and / or the filling gas manifold with an afterburner for afterburning the filling gases in order to prevent the emission of toxic gases.
  • the invention allows the temperature of the filling gases to be significantly reduced even before they enter the filling gas manifold.
  • constructions can be used in the filling gas manifold that would not be usable at very high temperatures of the filling gases, or that could only be used with particular effort.
  • a construction of the coking furnace according to the invention is particularly advantageous, which is characterized in that the filling gas collecting line has a slot running in the longitudinal direction and sealed by means of a partially openable band arrangement made of elastic material, and the collecting device has a filling gas inlet element projecting through the slot with partial opening of the band arrangement into the filling gas collecting line a middle lead-in area with a large cross-section and edge-side opening areas with tapering cross-sections, so that it can simultaneously serve as an opening element for the belt arrangement.
  • the collecting device is therefore permanently connected to the filling gas manifold, although the coke oven filling truck can nevertheless be moved in the longitudinal direction of the coking oven without any hindrance.
  • the filling gas inlet element is «always automatically in the right place.
  • the details of such continuous introductory constructions can be seen in the prior art for other types of collecting devices (cf. DE-C-25 29 660), so that further explanations are unnecessary here.
  • pre-filters with filter materials such as ground dolomite, lime, coke or coal can be used for the filling gas cleaning, that the filling gas cleaning continues to protect the actual dedusting filter glowing dust particles can have an upstream spark trap that the suction fan of the filling gas cleaning can contain devices for regulating the suction volume and that the control of the entire filling gas suction and cleaning should of course be designed in such a way that the suction power is throttled between the individual filling processes.
  • the coking furnace 1 shown in FIG. 1 has a multiplicity of horizontal coking chambers 2, which are closed off on the upper side by an furnace ceiling 3.
  • filling holes 5, which can be closed by filling hole covers 4, are provided for each of the coking chambers 2, via which coal can be filled into the coking chambers 2.
  • On the furnace ceiling 3 there are also rails 6 on which a coke oven filling truck 7 can be moved in the longitudinal direction of the coking oven 1.
  • the coke oven filling car 7 is provided with filling tubes 8 which can be lowered into the filling holes 5 of the respective coking chamber 2 and with a collecting device 9 for the filling gases which are produced during filling.
  • four filling holes 5 are provided for each coking chamber 2, so that the coke oven filling wagon also has four filling tubes 8.
  • the collecting device 9 has collecting hoods which are arranged coaxially with the filling pipes 8 and can be placed on the edges of the respective filling holes 5.
  • These collecting hoods 10 are arranged coaxially to the filling tubes 8 and are designed like a cylindrical telescope.
  • the filling gases collected with the collecting device 9 can be supplied to a filling gas cleaning device, not shown.
  • each coking chamber 2 of the coking furnace 1 shown has a riser 11, which is connected to a template, not shown, for extracting combustion gases.
  • this coke oven filling car 7 has a cover lifting device 12 for lifting the filling hole cover 4 as well as a filling hole cover and filling hole cleaning device 13.
  • the construction of the coking furnace 1 can be seen particularly clearly from FIG. 3. It is not shown in FIG. 3 that the filling gas cleaning is arranged stationary on or on the coking furnace 1. It can be seen, however, that a stationary filling gas manifold 14 is provided on the furnace ceiling 3. The stationary fill gas manifold 14 is connected to the fill gas cleaning, not shown.
  • the collecting device 9 on the coke oven filling car 7 can be connected to the filling gas collecting line 14.
  • the individual collecting hoods 10 of the collecting device 9 are connected to a common filling gas manifold 15.
  • the filling gas manifold 15 in turn can be connected to the filling gas manifold 14.
  • the filling gas collecting line 14 has a connection device 16 at the level of each coking chamber 2.
  • connecting device 16 has a connecting piece 18 which can be closed by a closure flap 17.
  • the filling gas elbow 15 has a mating connector 19 which can be sealingly attached to the connecting piece 18 of the connecting device 16.
  • connection device 16 in connection with the filling gas elbow 15 can be seen in FIG. 4 in an example.
  • the closure flap 17 can be opened automatically.
  • the closure flap 17 is pivotally mounted and can be actuated via a pivot lever 20.
  • An opening bracket 21 assigned to the counter socket 19 interacts with the pivot lever 20.
  • the mating connector 19 can be extended telescopically overall, specifically by means of a hydraulic system 22, which is only shown schematically and also moves the opening bracket 21 at the same time.
  • the filling gas manifold is provided with thermal expansion compensators, which always ensure precise alignment in the area of the connection devices.
  • FIG. 5 shows a section of an exemplary embodiment of a coking furnace 1, in which the filling gas manifold 14 has a slot 24 which runs in the longitudinal direction and is sealed by means of a partially openable band arrangement 23 made of elastic material.
  • the collecting device has a filling gas introduction element 25 which projects through the slot 24 and partially opens the band arrangement 23 into the filling gas manifold 14.
  • the filling gas introduction element 25 grips the belt arrangement 23 in the introduction area and lifts it slightly from the slot 24.
  • the slot 24 is otherwise covered by gratings.
  • the belt arrangement 23 in FIG. 5 has a belt clamped on one side, the edge-side clamping of which is realized at a clamping angle to the grating 26 which corresponds to half the opening angle. This is particularly cheap in terms of wear.
  • the collecting device 9 has a bypass valve 27 for the introduction of fresh air.
  • the temperature of the collected and extracted filling gases is reduced, so that trookene filters can be used in the filling gas cleaning.
  • FIG. 4 shows a collecting device 9 in which a pressure relief valve 28 is provided.
