Definitions

  • the invention relates to a method for sealing horizontal chamber coking ovens from the atmosphere in the area of the coke oven doors closing the top sides by tightening the circumferential sealing edge and on the inside of a corking plate with a spacing between the cage plate and the latching hooks projecting on the chamber frame.
  • the invention also relates to a coke oven with coke oven doors which close the head sides and which can be pressed against the chamber frame, which has a coking plate which is kept at a distance on the inside of the door body, a circumferential, spring-loaded sealing cutting edge with reset protection and pressure elements which influence the door body in order to carry out the method.
  • the coke oven doors provided with a heavy stone plug and a sealing system are pulled out by operating machines from the opening of the coke ovens after unlocking, pivoted, cleaned and then reinserted and locked.
  • the known coke oven doors consist of a heavy cast body or a correspondingly heavy welded construction, on which a ceramic stopper of about 0.4 m depth and a width corresponding to the furnace chamber is attached for thermal protection of the door body.
  • This door construction has a weight of up to 1o t for a modern horizontal chamber coking furnace with large dimensions and is usually pressed onto the chamber frame by means of two locking hooks, which are actuated via spindle arrangements, which in turn is attached to the wall protection plates and anchor stands of the coke oven.
  • the main task of the coke oven doors in general, as mentioned, is to close the side openings required for emptying the coke oven in a gas-tight manner during the coking process in order to secure the coking process and to avoid emissions to the atmosphere.
  • the coke oven doors have all-round sealing edges, which are placed, for example, on sealing plates designed as membranes. The sealing plates and thus the sealing edges are pressed against the chamber frame with a contact pressure of approximately 10 kg / cm sealing edge length. Depending on the size or height of the coke oven, a contact pressure of 15 t and more is necessary to ensure sufficient tightness of the coke oven. This high contact pressure is transmitted from the door body to the chamber frame via the latch hook or latches.
  • spring pots or similar units are pretensioned when the door is put on, which must then apply the necessary contact pressure. Up to now, two such spring pots per door have been used in ovens of 5 to 7 m in height.
  • the invention has for its object to provide a method that provides a short-term adaptable and safe sealing of the coke oven to the respective course of the chamber frame and to propose a suitable coke oven with an easy-to-handle and sealable over greater adaptation paths coke oven door.
  • the object is achieved according to the invention in that the coke oven door equipped with rigid locking bolts is suspended from above into the locking hooks and the coke oven door / chamber frame is continuously actively tensioned over the entire length of the peripheral sealing surface.
  • a coke oven door which is lightly constructed by the selected steel construction with coking plate can be hung up or hung in from the operating machine, so that it is in the same position in each case before the application of the clamping forces.
  • the tensioning forces are only applied when the door is precisely fixed.
  • the pre-stressed sealing blades which are still a short distance from the chamber frame when hanging, are now guided against the furnace frame and then only clamped against the chamber frame at the edge and immediately above the sealing edge in the area of the all-round sealing surface of the coke oven door / chamber frame.
  • the previous centrally arranged spring assemblies and the pivoting locking bolts can thus be dispensed with entirely.
  • the door or the sealing plate is only stressed in the area in which a relative movement in the direction of the chamber frame is necessary in order to achieve the desired seal to lead. Because of the method and the design of the coke oven door and its suspension, high pressures can be applied without any problems, although these are considerably lower than the contact forces to be applied by the central spring pots or spring assemblies.
  • the required contact pressure is generated linearly in the area of the locking bolts and locking hooks and is transmitted into the chamber frame.
  • the door body With such a transfer of the necessary pressure forces into the chamber frame, the door body can remain completely free of stiffening parts and can thus be made elastic overall.
  • the door body itself is no longer required for the transmission of the pressure forces.
  • the door body construction thus remains free of bending forces due to the thermal influence or can yield to it as necessary.
  • this type of transmission of the contact pressure has the advantage that the transmission path is significantly shortened and can be applied precisely in a targeted manner.
  • a coke oven door is particularly suitable for applying the necessary pressure forces, in which the pressure element is designed as a hollow body with a variable volume, which is enclosed by a U-profile cage arranged with the open side facing the sealing plate.
  • the pressure element is designed as a hollow body with a variable volume, which is enclosed by a U-profile cage arranged with the open side facing the sealing plate.
  • Such a hollow body is particularly suitable for generating the necessary pressure forces and for transferring them in the desired uniform shape in terms of area or line.
  • a particularly expedient embodiment according to the invention is to be seen in the fact that the sealing plate is bent, bent and equipped with a U-professional cage according to the invention by the hollow body lying directly on the chamber frame and acting on it.
  • a coke oven door advantageously represents a structural unit that only has to be supplemented by elements for attaching the door lifting claws and locking bolts. It is thus characterized by low manufacturing costs, favorable installation and maintenance conditions and, above all, when appropriate material is used for the hollow body, by completely closing off the coke oven from the atmosphere due to the relatively large sealing surface.
  • the size or better the work surface of the support of the hollow body the chamber frame can be influenced by the shape of the hollow body or by its quality.
  • the sealing surface can even be varied during operation, ie during the cooking process.
  • a distributor strip made of heat-insulating material between the hollow body made of heat-resistant material, which is designed to be pneumatically or hydraulically actuated, and the sealing plate.
  • the hollow profile rests a hose, so that it is protected from the more or less hot sealing plate and its shape and contact surface can be influenced by the shape of the distributor strip.
  • the U-profile cage is intended both to protect the hollow body and as an abutment, for which purpose it is arranged with the free web or flank ends resting on the sealing plate.
  • the webs of the U-profile cage are slotted according to the invention or they have transverse slots so that the U-profile can easily adapt to the bending shape of the chamber frame.
  • the U-profile cage is divided into partial lengths which are connected to one another via joints, so that it is given additional mobility in the direction of the furnace axis. In addition, the assembly and disassembly is much easier.
  • spring pressure cylinders are arranged on the U-profile cage at a distance from each other, which are supported on abutments connected to the sealing plate, for example Angle profiles attached adjustment angles with adjustable pressure screw. These angle profiles also serve to stop the holding device for the door lifting claws and to attach the foot pieces or the spacers of the coking plate.
  • the setting angles are expediently arranged displaceably and fastened to the angle profile by means of a pressure screw. This results in a certain readjustment or presetting of the pressure forces of the spring pressure cylinders.
  • a particularly uniform transmission of the contact pressure and thus a good seal can be achieved according to the invention in that a large number of connecting elements is provided over the height of the door body or the chamber frame and is formed by locking bolts and locking hooks of the same design. So far, only two pairs of locking hooks and a rotatable locking bolt have been used in the known coke oven doors. From these few connecting elements, the door, which is up to 7 or more meters high or rather long, must be pressed evenly against the chamber frame. The numerous locking bolts and locking hooks distributed over the height of the door facilitate the application of the necessary contact pressure and ensure a uniform seal over the entire length of the coke oven door. It is advantageous to attach the locking hooks and locking bolts approximately 1/2 to 1 m apart.
  • a simple construction and at the same time reliable transfer of the contact pressures is achieved in that the locking bolts are correspondingly fastened to the U-profile cage with the locking hooks arranged on the chamber frame, running across the door body and extending to the U-profile cage or one over the entire length of the door body arranged central strut or the Locking device are arranged supporting.
  • Various variants are proposed here, the last of which is particularly suitable for existing coke oven doors in which, for some reason, one cannot or does not want to do without the existing locking devices.
  • the continuous design of the locking bolts leads to a further simplification of the construction, but can lead to difficulties when hooking in the coke oven door if the chamber frame is bent differently.
  • the sealing cutting edge is arranged on the chamber frame, the inner edge of which is chamfered, or is part of the chamber frame.
  • the inside of the sealing plate is preserved as a surface, so that any contamination that may still occur can be easily removed, while contamination can easily occur in the area of the chamber frame and the sealing cutting edge without this immediately leading to leaks.
  • the chamfering of the inner edge of the chamber frame ensures that the coking gases are brought up to the sealing cutting edge with full heat, so that contamination and contamination, in particular due to graphite formation, cannot occur here.
  • the sealing plate In particular with new coke oven doors, as mentioned, it is advantageous to edge or bend the sealing plate at the edge and to arrange the hollow profile there.
  • the locking bolts can be molded onto the arch or its outer wall or connected to it at its deepest point in the arch.
  • the hollow body In order to ensure that the hollow body assumes the intended position when the coke oven door is inserted, it is provided according to the invention that the hollow body is point-connected to the web of the U-profile cage or the deepest part of the arch.
  • the mobility of the sealing plate also in the region of the spacer pieces carrying the coking plate is achieved according to one embodiment in that the sealing plate is connected to the center strut designed as a carrier by means of the spacing pieces which are at a distance from one another and hold the coking plate.
  • the contact surface between the foot piece or the spacers is thus kept very small, the edge region advantageously being unaffected by the foot piece. In this area, however, a deflection of the sealing plate is particularly favorable. Otherwise, the spacers or their foot pieces hardly influence the mobility of the sealing plate, because they are arranged at a large distance from one another over the length of the door body.
  • the slight influence on the deflectability of the sealing plate is particularly advantageous in that the sealing pieces and their foot pieces are rectangular and are connected to the sealing plate and the middle strut and on have a cover on the end opposite the foot piece, on each of which corresponding connection elements are provided with elements formed on the coking plate.
  • the sealing plate made of a flexible steel is effectively protected from the high-temperature gases by the sealing plate being arranged between an insulating layer held by the foot pieces of the spacers and protected by a cover plate and door body or central strut. The insulating layer thus protects the sealing plate and door body at the same time.
  • the insulating layer is arranged between the sealing plate and the door body or central strut.
  • the door body remains protected by the insulating layer, even if it consists only of the central strut, so that it is only necessary to choose a sealing plate which can absorb correspondingly high temperatures.
  • the invention is characterized in particular by the fact that a method is created which ensures a uniform and targeted application and introduction of the contact pressure.
  • a coke oven door is created which is characterized by a very low weight, high elasticity, in particular in the transverse direction, and easy handling.
  • there is a gas-tight seal on the side openings of the coke oven which contributes to a substantial reduction in emissions and immissions from the coking plants.
  • With a considerable reduction in weight and the convenient handling of the coke oven doors it is also possible to simplify the door lifting and operating machines.
  • Fig. 1 shows a perspective view of an elastic coke oven door 1 in lightweight construction.
  • the door body 2 of the coke oven door 1 is formed here only by the sealing plate 3 designed as a membrane, the angle profile 4 running parallel to the edge, and the sealing cutting edge 5.
  • the sealing edge 5 is actually not part of the coke oven door 1, but rather the chamber frame 7.
  • the angle profile 4 serves as a holding device 6 both for the holding claws (not shown) and for the pressure elements and their accessories.
  • a plurality of locking hooks 8 and locking bolts 9 are provided as connecting elements between the door body 2 and the chamber frame 7.
  • a circumferential light frame designed as a U-profile cage 1 0 is hooked into the corresponding locking hooks 8 of the chamber frame 7 via the locking bolts 9. Since all other parts of the door body 2 are connected to this U-profile cage 10, a fastening or connection of the door body 2 to the chamber frame 7 is thus also achieved at the same time.
  • the U-profile cage 1o can consist of short, approx. 0.5 to 1 m long individual pieces, which are connected by joints are connected. This gives the U-profile cage 1o a sufficiently large elasticity in the longitudinal direction and thus allows the sealing plate 3 or the entire coke oven door to adapt to the bends of the chamber frame 7.
  • the pressure element 11 within the U-profile cage 1o is the pressure element 11, in the example shown a hydraulically or pneumatically operated hollow body 12.
  • the hydraulic or pneumatic operation of the hollow body 12 causes the membrane or the sealing plate 3 against the sealing cutting edge 5 and the Chamber frame 7 pressed.
  • the sealing plate 3, the cutting edge 5 and the chamber frame 7 thus form the gas-tight seal of the coke oven against the atmosphere.
  • the special arrangement and design of the pressure element 11 leads to a uniform distribution of the required contact pressure over the entire length of the sealing cutting edge 5. The forces required for this are no longer transmitted via the door body 2, but rather directly via the locking bolts 9 and locking hooks 8 in the chamber frame 7 headed.
  • the U-profile cage 1o encloses the hollow body 12 or the pressure element 11. Its flanks 14, 15 are provided with weakening slots transversely to their longitudinal direction in order to further increase their flexibility.
  • the hollow body 12 rests in it on the distributor bar 17, which preferably consists of heat-insulating material in order to additionally protect the hollow body 12 from the heat emanating from the coke oven.
  • the distributor bar 17 also serves to equalize the contact pressure.
  • the lying in the U-profile cage 1 0 hollow body 12 is ge via the spring pressure cylinder 18 in each case in a predetermined position brought and held, the web ends 16 of the U-profile cage 1o at least at the beginning of the pressing process on the sealing plate 3.
  • the individual spring pressure cylinders each have an upper and a lower flange 19, 20 in which bores 21, 22 are arranged for the passage of the connecting screws.
  • the spring 24 is arranged, which brings the desired resilient connection between the rest of the door body and the sealing system.
  • a setting angle 25 is provided as a connection between the spring pressure cylinder 18 and the angle profile 4, which is arranged so as to be displaceable via the elongated holes 28. The setting is effected via the pressure screw 27 guided in the cross piece 26.
  • the flanks 14, 15 of the U-profile cage 10 are slotted as mentioned, i.e. they have transverse slots 3o arranged at intervals.
  • the guide bolts 31 in the region of the flanks 14, 15 can be inserted into recesses formed in the sealing plate 3 and thus make assembly easier by precisely specifying the predetermined position of the U-profile cage 10.
  • the sealing cutting edge 5 is arranged close to the inner edge 35 of the chamber frame 7 and is thus exposed to the hot gases.
  • the opening 36 in the locking hook 8 is the locking bolt 9 adapted so far that it has a sufficient but not too large game.
  • the hot gases are guided in the rest of the cavity or gas exhaust duct, which is formed between the door body or the sealing plate 3 and the coking plate 39 held at a distance from the door body by spacers 38.
  • Fig. 2 illustrates that the gases each reach the area of the sealing cutting edge 5 without difficulty and without cooling beforehand. Therefore, there will be hardly any caking or dirt in this area.
  • the inner edge 35 is chamfered for this.
  • FIG. 3 shows a longitudinal section through one of the two furnace heads with the coke oven door inserted, the sealing plate designed as a membrane seal being loaded precisely in the area of the sealing cutting edge 112 via the all-round hollow bodies.
  • the coke oven door is labeled 1 0 1
  • the illustration shown in FIG. 4 is a lighter construction.
  • the insulating layer 119 is also arranged over the distance Pieces 123, 124 is held on the door body lo3 or the sealing plate 11o.
  • the spacers 123, 124 carry the coking plate 12o at the end, which consists of individual shields 125, 126, each of which is screwed or hidden to the shield holders 127.
  • the bottom nozzle 128 is screwed to the actual door body lo3 example, keeping on the cover plate 121, the insulating layer 119 and simultaneously the sealing plate 11 0th
  • the gas discharge duct 117 is formed, through which the gases released are discharged in the direction of the template.
  • the spacers 123 consist of the foot pieces 128, which are screwed together by means of fastening screws 129, 13o as well as FIG. 6, carry the shield holders 127 and thus the actual shields 125, 126.
  • the individual shields have reinforcing ribs 131 on the underside , and bores 168, which are designed to correspond to the connecting elements 167 on the cover 166. As a result, the shields can be hidden during assembly with the spacers 123, 124 or the shield holders 127. A screw connection is also advantageous.
  • FIG. 4 shows an embodiment in which the sealing plate 3 is only designed to reach the chamber frame 7. This is followed by the U-profile cage 1 0 , in which the hollow body 12 is arranged. U-profile cage 1o and sealing plate 3 are welded to one another, screwed or otherwise connected, so that they form a structural unit and are connected to the chamber frame 7 via the locking bolts 9 in the locking hooks 8 can be.
  • the hollow body 12 rests on the chamber frame 7. Since this is approximately uniformly warm or hot, the hollow body is only exposed to limited temperatures, especially since the hollow body cannot be directly influenced by the hot gas.
