Definitions

  • the invention relates to a device for extracting filling gases in coking ovens, with which part of the filling gases is drawn off from an opening in the ceiling of the furnace to be filled and is introduced into a corresponding opening of a neighboring furnace, preferably the furnace after the next, with a for transferring the filling gases on a cart along the battery movable, liftable and lowerable elbow is used, the downwardly projecting annular ends are provided with a ring bar and the gas-tight connection between the ends of the elbow and the furnaces is made by lowering the elbow in water cups, which the upper ends of riser tubes which can be inserted into an opening and can be closed with lids are formed.
  • the filling gases are suctioned off in such a way that, after the cover has been lifted off, the elbow is lowered onto the openings in the furnace ceiling or into the water cups of the risers inserted into the openings , so that a smoke-tight closure is present.
  • a partial suction of the filling gases from the chamber to be filled takes place through the manifold.
  • the elbow is raised again and the risers are closed with the covers.
  • explosive deflagrations often occurred when the transfer pipe, which was designed as a manifold, was lifted, which were not only found in water-immersed transfer pipes, but also in transfer pipes with other sealing systems.
  • the explosive deflagrations are due to the fact that when the manifold was lifted, the remaining filling gases combined with oxygen to form an explosive mixture that was ignited at high temperatures.
  • the object on which the invention is based is to avoid explosive deflagrations which can occur when the manifold is lifted after the filling process has ended and after the filling gas suction has been completed. This object cannot be achieved with the device known from US Pat. No. 3,968,014, in which the air supply serves a different purpose and takes place at a different time.
  • the invention consists in that at the end of the elbow connected to the furnace to be filled, the closure portion immersed in the water cup is shorter than at the other end, such that when the elbow is lifted at its shorter closure portion the water cup closure is released by the formation of an annular gap while the other closure section is still immersed in the water cup.
  • Another embodiment of the invention provides that the quarter elbow of the elbow connected to the furnace to be filled is replaced by a sleeve in which a piece of pipe is displaceable in the vertical direction, which is closed at the top and provided at its lower end with a closure section which immersed in the water cup in the lowered position and free of it in the raised position.
  • the elbow (1) consists of a U-shaped piece of pipe, the ends (2, 3) of which are formed as quarter arcs are each connected to an oven chamber, one of which is filled while the other , usually contains the next but one, fully or partially cooked coke.
  • riser pipes (4) are inserted, the upper ends of which, as shown in the drawing, are designed as a water cup 5.
  • the water cups can be swiveled through lids, not shown be closed.
  • a portion of the filling gases can be sucked into the furnace chamber in which the fully cooked coke is located, if necessary after the suction has been increased.
  • the method of filling gas extraction corresponds to that described in DE-A-2 920 406.
  • the invention provides for a connection to the outside air in the region of one end of the elbow, preferably at the end which is introduced into the furnace to be filled, after the filling process has ended, without the gas-tight connection being established the other end is lifted with the furnace chamber in operation, so that purge air is sucked through the transfer pipe.
  • This takes place in the embodiment shown in FIGS. 1a and 1b in that at one end of the elbow the closure section (6) which is immersed in the water cup (5) and is designed as a ring strip is shorter than at the other end.
  • the elbow can be brought from the working position shown in Figure 1a by slightly lifting it to the flushing position shown in Figure 1b, in which the right end (2) of the elbow with the shorter closure section (6) from the water cup (6) 5) has escaped while the gas-tight seal is maintained at the other end (3).
  • Purge air is drawn in through the gap formed in this way, as indicated by the arrow, which flows through the elbow (1) forming the transfer pipe and is drawn off via the chamber which contains the fully cooked coke.
  • one of the quarter bends of the elbow (1) is replaced by a sleeve (10) in which a piece of pipe (11) is arranged to be displaceable in the vertical direction.
  • This piece of pipe which is closed at the top, contains at its lower end the annular closure section (6) which, in the lowered working position (FIG. 2a), dips into the water cup (5), while in the raised position (FIG an annular stop (12) of the pipe section (11) is delimited, lies above the water cup, so that purging air can be sucked through the elbow through the elbow (1).
  • FIGs 3a and 3b show an embodiment with an internal lid lifter.
  • Both quarter bends of the elbow (1) are replaced by vertical pipe sections (13) which are provided at their lower end with an annular closure section (14) which dips into the outer water cup (16) of a double water cup closure (15), which one inner ring-shaped water cup (17) concentrically surrounds.
  • a bell-shaped cover (18) is arranged in both pipe sections (13) in such a way that it can be moved from an upper position, in which it closes an upper opening (20) of the pipe section (13), to a lower position, in which lower edge immersed in the inner water cup (17), while the upper opening (20) of the pipe section (13) is open.
  • a rod (19) is used to actuate the cover (18), to which the cover is releasably attached, so that the rod is removed from the cover when it is in the water cup ( Figure 3b, right half) ) can be separated and the cover forms the sealing cover for the riser pipe (4).
  • FIG. 3a shows the working position in which the filling gases can be sucked from one furnace chamber into another via the pipe sections and the central section of the elbow (1)
  • FIG. 3b shows the rinsing position, in which the right cap closes the corresponding riser pipe and air can enter through the upper opening (20) of the right pipe section (13).
