Definitions

  • the invention relates to a suction device for emissions from furnace doors of one or more juxtaposed, e.g. to a coking furnace battery of combined coking furnaces, each with a suction hood fixedly attached above the furnace doors, which is connected to a collecting line, and with anchor stands arranged on both sides of the furnace doors.
  • DE 32 18 177 A1 discloses a method and a device for extracting carbonization gases in the area of coke oven doors.
  • a suction hood with a suction channel is arranged above the respective oven door. This has the disadvantage that in particular the emissions occurring in the lower region of the furnace door are not reliably recorded.
  • DE-22 24 768 C3 discloses a device for suctioning off a coke oven extinguishing hall with a suction channel arranged in the area of the hall ridges with controllable suction flaps, suction and connected flue gas cleaning.
  • a suction channel arranged in the area of the hall ridges with controllable suction flaps, suction and connected flue gas cleaning.
  • DE 23 26 630 A1 discloses a dedusting system for coke oven batteries with a mobile dust cover, which is assigned to the area of a single coke chamber and is arranged to be displaceable from chamber to chamber.
  • the dust cover can be moved together with a guide carriage and a fire truck in front of a coke chamber to be emptied.
  • a collecting line can be placed parallel to the displacement path of the dust cover and connected to a stationary central dedusting unit, to which the dust cover can be connected in any working position.
  • the dust cover is only used to trap the dust generated when the coke is pressed and the steam generated when it is extinguished.
  • the object of the invention is to provide a suction device of the type mentioned at the outset, with which the emissions occurring during the coking process on leaky furnace doors can be effectively extracted and which is suitable both for individual and several combined coking ovens or coking reactors as well as for the known coking furnace batteries .
  • This releasable mounting of the cover can be equipped in such a way that the cover can be inserted loosely in front of the furnace door in the holding means of the anchor stand and then held rigidly, or it can also be pivoted on the one anchor stand be articulated so that it is folded in front of the oven door for filling and for the duration of the coking process, so that it can then be folded away before the coke is pressed. Access to the leveling opening on the machine side can be ensured by a lockable opening in the cover.
  • the cover can, for example, be hood-shaped and can seal around the oven door directly against the oven wall.
  • the cover can also lay against the anchor stand.
  • the gap is expediently sealed with a sealing strip or another material, for example fiber material.
  • the width of the cover advantageously corresponds at least to the distance between two adjacent anchor stands, to which it can be fastened in tight contact against the outer surfaces thereof.
  • the cover according to claim 3 is expediently attachable to the anchor stand, wherein according to claim 4 it advantageously lies tightly in the working position with its upper edge on the lower edge of the extractor hood.
  • the height of the cover preferably corresponds at least to the height of the respective oven door.
  • Another advantageous measure for a simple and effective mounting of the cover consists in that on the outer surfaces of the anchor stands and on the cover on the one hand oblique hooks and on the other hand corresponding projections are arranged.
  • the hooks and projections expediently cooperate on both sides, e.g. sloping surfaces on which the cover can be slid under its own weight into a sealing system against the adjacent anchor stand and the suction hood in between.
  • the space between the door and the extractor hood is completely closed except for the lower air inlet opening, so that no more emissions can escape.
  • cover can be pivoted via an articulated connection to one of the anchor stands and can be folded in front of the adjacent furnace door.
  • claim 9 preferably contains Articulated device easily connectable parts, such as hinge pins and pluggable hinges, with the help of which the cover can be easily attached and removed.
  • This placement and removal or relocation of the cover from one coking oven to another is preferably carried out according to claim 10 by means of a setting device which can be moved in front of the respective coking oven and by means of which the cover can be inserted in its holder or can be moved from one coking oven to another, for which purpose according to claim 11 the cover has lifting pockets for the engagement of the setting device.
  • Both embodiments of the suction device are suitable both for individual coking ovens or coking reactors as well as for furnace or reactor units with several furnace chambers.
  • the one or more of them which are arranged according to the filling sequence and sealingly in the working position on the anchor stands adjacent to the respective furnace door and the associated exhaust hood, are either folded away from the furnace door or by the setting device after the emission phase has ended Intervention in the lifting pockets removed or implemented.
  • the latter is necessary in particular in the case of different filling sequences of the coking ovens in a battery with a large number of coking ovens.
  • the drawing shows two exemplary embodiments of a suction device 1 or 20 for emissions from the furnace chambers 2 of a coking furnace battery 3 that can be used both on the machine side and on the coke side.
  • Each coking oven 4 is provided with a stationary suction hood 7 above its coke oven doors 5 or chamber openings 6.
  • the lower hood edge 8 is aligned with the outer surfaces 9 of the anchor stand 10.
  • the suction hood 7 extends in width from one to the adjacent anchor stand 10. All the suction hoods 7 on one side of the furnace are connected to a stationary collecting line 11.
  • a plate-shaped or hood-shaped cover 12 which covers the space in front of the chamber opening 6 or the furnace door 5 and is detachably connected to the anchor stands 10.
  • hooks 13 are attached to the anchor stands 10 in the first exemplary embodiment according to FIG. 1, into which the cover 12 can be suspended by means of known projections 14.
  • the chamber opening 6 and its door 5 are covered like a hood by the cover 12, which rests with its upper edge on the edge 8 of the suction hood 7 and with its vertical edges on the outer surfaces 9 of the anchor stand 10 arranged on both sides of the furnace door 5.
  • the width of the cover 12 thus extends from one to the adjacent anchor stand 10 of a coking furnace 4 in order to achieve a sufficient seal up to the level of the chamber sole.
  • the cover 12 is interchangeable and can be implemented with a separate transfer device 17 which can be moved along the coking oven battery 3 in accordance with the pressure schedule and the filling sequence between the anchor stands 10. Accordingly, lifting pockets 18 are provided in the region of the vertical center plane M of the cover 12 for the engagement of matching lifting hooks 19 of the transfer device 17.
  • a cover 12 is pivoted along the coke oven battery 3 on every second anchor stand 10 in such a way that each of the covers 12 can be folded either in front of the one oven door 5 or in front of that of the adjacent coking oven 4.
  • These locking devices 22 are designed such that they lock both the cover 12 pivoted from the left and the right against the outer surfaces of the suction hood 7 and anchor stand 10.
  • the covers 12 have known sealing strips that run around on both sides. These ensure that the coking ovens 4 are sealed in every working position downward, the space 15 already described in relation to FIG. 1 opens between the oven door 5 and the cover 12 into an air inlet opening 16 through which no gas is emitted as a result of sufficient suction in the suction hood 7 and collecting line 11.
  • the hinge devices 21 consist in a known manner of hinge and free hinge pin above. In order to be able to detach the covers 12 from the articulated connection by means of the lifting pockets 18 for replacement or relocation, the articulated straps need only be lifted off the articulated bolts.
