Definitions
- the invention relates to a device and a method for sealing a leveling door opening of a coke oven chamber according to the preamble of claims 1 and 15, respectively.
- the coking coal When coking hard coal, the coking coal is usually filled into the coke oven chamber through filling holes in the chamber ceiling. With this so-called loading in bulk operation, pouring cones are formed under the filling holes, which have to be leveled during the filling process with a leveling device in order to fully utilize the chamber space and to leave free discharge space for the filling gases below the chamber ceiling.
- the device required for leveling with a leveling rod that can be moved into the furnace chamber from the outside through a so-called leveling door opening, is usually mounted on the coke press machine referred to below as the printing machine.
- This printing machine can be moved along the coke oven battery from the coke oven chamber to the coke oven chamber in order to use a pressure rod to remove the fully cooked coke cake from the
- the printing press has actuating devices for opening and closing or locking the coke oven chamber doors located on the machine side and the leveling doors closing the leveling door opening.
- DE 33 40 067 C2 discloses a sealing device for the leveling door opening with a housing which can be sealingly connected to the leveling opening and from which a transfer pipe branches off to an adjacent coke oven chamber.
- DE-AS 11 27 868 discloses a device for preventing the filling gases from escaping through the leveling opening with a tube surrounding the leveling rod, the length of which is approximately equal to the distance between two adjacent cross bars of the leveling rod.
- Nozzles of air are blown in the direction of the leveling door opening and extracted there with the suction fan.
- the suction can be adjusted with a throttle in such a way that an air seal is to be created in the housing outside the leveling door opening, which should prevent gases and flames from escaping from the leveling door opening.
- a closed space is to be created in front of the leveling door opening, in which a pressure builds up corresponding to the pressure in the coke oven chamber, so that there is no noticeable pressure difference between the coke oven chamber and the space in front of the leveling door opening.
- This device prevents filling gases from entering the leveling door opening.
- the setting of the suction with a throttle is relatively imprecise, so that under certain circumstances air is blown into the coke oven chamber or filler gases are sucked out of the coke oven chamber.
- the invention has for its object to provide simple devices and methods that ensure a closed space outside the bulldozer opening and thus prevent the emissions of filler gases through the bulldozer opening.
- the invention is based on the basic idea that the negative pressure present in the coke oven chamber during filling with coking coal is also maintained in the area of the leveling door.
- a seal is achieved which corresponds in its sealing function to a closed leveling door.
- the area in front of and / or in the leveling gate opening is either by fluidic measures, i. H.
- the suction fan according to claim 1 is - preferably - set such that a flow in the space in front of the leveling door opening no longer occurs. This creates a flow dead zone in the space in front of and / or in the leveling door opening. The flow in this area is measured at a measuring point and the measuring signal is used to regulate or control the suction fan.
- suction fan outlet it is also possible to connect the suction fan outlet to an adjacent coke oven chamber.
- the negative pressure of the neighboring coke oven chamber is also used.
- the suction is operated in such a way that filling gases are sucked into the neighboring furnace.
- the space in front of the leveling door opening is closed by mechanical sealing in such a way that no filling gases can escape.
- the leveling rod is sealed at the top and bottom by the sealing plates.
- the leveling rod is sealed at the side by sealing strips. This sealing of the leveling rod from the outside in combination with the crossbars forms a closed hollow box, since the sealing plates seal at least the area of two crossbars.
- the sealing plates can be mounted such that they rest on the side bars, on the cross bars or on side and cross bars of the leveling rod.
- a pressure medium e.g. B. springs are pressed against the side webs of the leveling bar.
- the reinforcement of the seal by the sealing strips on the side bars of the leveling rod, e.g. B. by means of springs is also possible.
- the sealing plates can also be arranged in the housing in such a way that they are pressed against the leveling bar by the vacuum present within the leveling bar, which likewise increases the sealing effect.
- the sealing plates can be provided with roundings and / or bevels on their edges. This prevents the leveling rod from hitting the edges of the sealing plates during the leveling process. It is also possible to divide the sealing sheet into several segments. As a result, the sealing plate can remove any unevenness in the leveling rod and
- the sealing plates can be equipped with abrasives for better durability.
- the housing can be dispensed with when using sealing plates, since a housing is formed by the sealing plates and the side webs of the leveling rod.
- the leveling coal collecting container can be arranged anywhere outside the area of the sealing plates.
- a seal of the inner cross section of the leveling rod is provided between the side webs.
- These sealing elements must be designed so that they can avoid the crossbars of the leveling rod.
- the space between the side bridges of the The leveling rod and the housing are sealed by one or more sealing strips arranged one behind the other.
- pendulum flaps in the housing.
- the pendulum flaps can be hanging in z.
- one-piece flap design can be arranged in the housing. They seal the cross section between the side bars of the leveling bar. If the leveling rod moves, the crossbars of the leveling rod press against the pendulum flap when approaching and touching it. The pendulum flap becomes
- Another option would be to seal the inner cross-section of the leveling rod with cellular wheels.
- Cell wheels are arranged in a cell wheel housing above and / or below the leveling bar in such a way that the cell wheel blades engage in an overlapping manner in the space between the side bars of the leveling bar. If the leveling rod moves, the crosswheels cause the cell wheels to rotate.
- the lower cellular wheel housing can be equipped with a coal discharge for the leveling coal.
- the cellular wheel can also be dimensioned such that the cellular wheel wings, like the pendulum flaps, seal the entire cross section between the side webs of the leveling rod.
- a sealing plate is arranged in the lower part of the housing opposite the cellular wheel, which seals at least the area of two transverse webs of the leveling rod and can also consist of the bottom plate of a housing surrounding the leveling rod.
- Another possibility of the inner leveling rod seal is the installation of movable rollers in a roller housing.
- the rollers are dimensioned such that they take up and seal the entire cross-section between the side bars of the leveling bar.
- the rollers can move up and down within the roller housing, thus avoiding the crossbars of the leveling bar.
- seals can be arranged several times in the housing. It is also possible to combine the suction fan with a seal by means of sealing plates and / or movable sealing elements.
- the housing can also be made so large that the leveling flap can be opened or locked within the housing.
- Shape design, material selection and technical conception do not have any special exceptions, so that the selection criteria known in the respective area of application are used without restriction.

- a suction blower 8 with a suction line 15 connected to the housing 1 is arranged above the housing 1.
- the suction fan is adjusted so that essentially no gas flow takes place in the housing 1 near the leveling door opening 5 of the coke oven chamber 6; rather, a flow dead zone 9 is formed in an end of the housing 1 or the one that is between the interior of the coke oven chamber 6 and the end of the housing door opening 5
- Suction line 15 located area. The filling gases are sucked out through the riser pipe 7 while ambient air is sucked out through the suction fan 8 and does not get into the coke oven chamber. Any flow is detected at a measuring point 10.
- sealing plates 11 and 12 are arranged in the housing 1 above and below the leveling rod 2, which is open at the top and bottom.
- the sealing plates 11 and 12 lie on the upper and lower edges of the side webs 3 and the cross webs 4 of the leveling rod 2 and protrude from the Housing 1 at its end remote from the coke oven chamber 6.
- the sealing plates 11 and 12 are made longer than the distance between two cross webs 4 serving as leveling bars. As a result, the leveling door opening 5 is always sealed to the outside by at least one cross bar 4 of the leveling bar 2 during the leveling process.
- the side webs 3 of the leveling rod 2 are also sealed by sealing strips 13 and 14.
- the seal with pendulum flaps can be seen from FIG. 3.
- two swing flaps 20 and 21 are shown, which can swing about axes of rotation 22 and 23, respectively.
