Definitions

  • the invention relates to a stationary gas transfer device for a coke oven with juxtaposed coke oven chambers, each of which has a gas opening, the gas transfer device covering gas openings of two adjacent coke oven chambers, each with a cover chamber, and the two cover chambers being connected in line with a transfer pipe, and the gas openings when a coke oven chamber is covered, lids within the lid chambers can be moved from an open position into a closed position by means of an actuating device and can be set into a rotational movement.
  • a gas transfer device of this type is known from DE-C-32 04 991. It is used to transfer the filling gases generated when filling a coke oven chamber into the neighboring coke oven chamber.
  • annular immersion cups filled with water are provided, into which ring-shaped aprons of the covers project on the outside of the cover.
  • the cover has a cylindrical stopper part protruding into the gas opening.
  • scrapers are arranged on the outer circumference of the cylindrical plug part, which clean the gas opening when the cover is put on by rotating the cover so far that the cylindrical plug part can be inserted into the gas opening.
  • the sealing of the lids does not meet the requirements, especially since pressure fluctuations caused by high-pressure suction or the filling process can cause the immersion cups to be emptied.
  • the immersion cups can also be empty when overpressure occurs.
  • the water either gets onto the furnace roof or into the coke oven chamber and forms strong coal and coke deposits in or at the gas openings and on the inside of the gas transfer device by mixing with coal dust. An undesired moistening of the refractory lining of the coke oven chambers can also occur, which is disadvantageous.
  • a gas transfer device which is movable on the furnace is known and is only positioned during the gas transfer over the covers of the coke oven chambers to be connected.
  • a steam nozzle through which the filling gases are sucked off and transferred, opens into the gas transfer device.
  • the gas transfer device is moved further, so that the covers of the coke oven chamber connected first are freely accessible from above.
  • a stationary gas transfer device which is provided with flaps, which flaps are open during the coking process and are only closed during the emptying of a chamber, in which case the gas transfer device is acted upon by inert gas .
  • the invention aims to further develop the known gas transfer devices in that coal and coke build-up are largely avoided and the gas openings are sealed even with larger ones Pressure fluctuations exist.
  • both the cover and the edge of each gas opening each have a sealing surface in the manner of a valve seat, which are matched to one another and pressed against one another in the closed position of the cover, and in that an inert gas is introduced into the gas transfer device.
  • an inert gas is introduced into the gas transfer device.
  • an inert gas such as nitrogen, feed gas line opens and the gas transfer device is acted upon with closed lids with an inert gas pressure which is above the pressure within the coke oven chambers.
  • the tightness is guaranteed due to the mutually adapted sealing surfaces, that is to say by a mechanically acting seal.
  • the gas transfer device can be pressurized with inert gas, which is dimensioned such that it is above the pressure inside the coke oven chamber, thereby preventing any escape of furnace gas, which represents a further safety factor.
  • inert gas provides effective protection against corrosion from the condensates accumulating on the inside of the gas transfer device.
  • a particular advantage of the device according to the invention can be seen in the fact that the outer dimensions of the gas transfer device can be kept very small by using the mechanically sealed cover, i.e. are only slightly larger than the lid diameter, which results in a decisive improvement in the very limited space on the ceiling of the coke oven.
  • An advantageous embodiment is characterized in that the sealing surfaces are frustoconical, the sealing surfaces of the covers or the edges of the gas openings each having an annular sealing strip. This ensures a particularly good seal.
  • the cover chambers are each provided with a top Removable chamber cover is provided and a lifting device for lifting the cover together with the chamber cover is arranged movable to all coke oven chambers on the coke oven.
  • the lifting device can expediently be moved along rails arranged horizontally on the coke oven and has a pivotable, as well as lifting and lowering cantilever beam that can be coupled to a cover.
  • the gas transfer device is provided with an explosion flap.
  • a method for filling a coke oven chamber of a coke oven with a gas transfer device is characterized in that two adjacent coke oven chambers which are connected to one another by line with a gas transfer device and one of which is filled are placed under negative pressure and the filling gases from the coke oven chamber to be filled be sucked off directly and from the adjacent coke oven chamber via the gas transfer device and that air is sucked in via an opening arranged in the vicinity of the gas transfer device.
  • the sucking in of air causes the oxygen contained in it to be burned with some of the filling gases, so that no tar caking of tar condensates, coal, graphite etc. can occur in the interior of the gas transfer device.
  • This burning out of the gas transfer device brings about a high level of cleanliness of the sealing surfaces of the covers and the gas openings, so that a perfect stacking of these sealing surfaces and thus a reliable seal is ensured after the covers have been closed.
  • the opening arranged in the vicinity of the gas transfer device is advantageously a leveling opening through which a leveling slide can be inserted laterally into the coke oven chamber, which removes the tips of the coke fill cones so that they do not hinder the gas flow inside the coke oven chamber.
  • Fig. 1 shows a section through part of a ceiling of a coke oven with a gas transfer device mounted thereon, which also cut is shown.
  • Fig. 2 illustrates a partially sectioned side view in the direction of arrow II of Fig. 1.
  • Fig. 3 is a section along the line III-III.
  • a filling opening 3, 3', ... for each coke oven chamber On the ceiling 1 of a coke oven with adjacent coke oven chambers 2, 2 ', ... are a filling opening 3, 3', ... for each coke oven chamber, to which a filling cart 4 for filling the coke oven chambers with coking coal can be connected gas-tight, and a gas opening 5, 5 ', ... provided, through which displaced furnace gas can escape from the coke oven chamber during filling.
  • a gas transfer device 6 is arranged at the gas openings 5, 5' of two adjacent coke oven chambers 2, 2 ', which is supported on the furnace ceiling 1 and the gas opening 5 of the one coke oven chamber 2 with the gas opening 5 'of the adjacent coke oven chamber 2' connects in terms of line.
  • the gas transfer device 6 is formed by two cylindrical, vertically directed cover chambers 7, 7 ', the inner diameter of which is somewhat larger than the outer diameter of covers 8, 8' which can be placed on the gas openings 5, 5 ', so that the covers 8, 8' within the lid chambers 7, 7 'are movable from an open position to a closed position in the vertical direction.
  • the lower ends of the lid chambers 7, 7 ' are fixed and gas-tight on the ceiling 1 of the coke oven.
  • the two adjacent coke oven chambers 2, 2 'associated cover chambers 7, 7' are connected in line with a transfer tube 9 which extends transversely to the cover chambers 7, 7 '.
  • An inert gas line 10 opens, which can be regulated or shut off by means of a valve 11.
  • an actuator 12 (see. Fig. 1), which is mounted according to the illustrated embodiment on the filling truck 4, which is movable along the entire coke oven from filling opening 3 to filling opening 3'.
  • This actuating device 12 has a frame 15 which can be displaced in a horizontal direction on a crossbar 13 of the filling truck 4 by means of a pressure medium cylinder 14 and which carries a carrier 16 at its lower end, which is carried out by means of a further pressure medium cylinder 17 which is on the one hand on the frame 15 and on the other hand on the Carrier 16 is mounted, can be raised and lowered.
  • the crossmember carries two at a distance 18 of the adjacent gas openings 2, 2 'arranged electromagnets 19, 19', which can be set in rotation by means of an electric motor 20, 20 '.
  • the liftable and lowerable cover 8, 8 ' are each attached to a lifting rod 21, 21' by means of a rotation driver connection 22, 22 ', which lifting rod 21, 21' protrudes from above into the interior of the cover chamber 7, 7 '.
  • a steel plate 23, 23' is attached to which the electromagnet 19, 19 'can be attached.
  • both the cover 8, 8 'and the edges of the gas openings 5, 5' each have sealing surfaces 24, 24 ', 25, 25' to achieve a tight fit, which are frusto-conical in the manner of a valve seat are designed, the sealing surfaces 25, 25 'of the cover 8, 8' have an annular sealing strip 36.
  • the annular sealing strip 36 is pressed against the sealing surface 24 or 24', so that there is a good sealing fit.
  • the Rotationsmit aloneharm 22, 22 ' is each formed by a on the lifting rod 21, 21' rotatably mounted crossbar 26 to which the cover 8, 8 'by means of U-shaped bracket 27, which are placed over the free ends of the crossbar, is held , so that the cover 8, 8 'is non-rotatably connected to the lifting rod 21, 21', but has a certain amount of lateral play to allow a safe centering of the sealing surfaces 24, 25 and 24 ', 25' coming into contact.
  • the lifting device has a vertical support 30, along which a horizontally directed cantilever support 31 which can be pivoted about a vertical axis can be adjusted in height, etc. by means of a crank handle 32.
  • a horizontally directed cantilever support 31 which can be pivoted about a vertical axis can be adjusted in height, etc. by means of a crank handle 32.
