Description

DETAILED DESCRIPTION OF THE INVENTION The invention comprises a caulking plate located forward in the direction of the furnace charge and held at a distance from the door body via a spacer piece to close the furnace top. Relating to a coke oven equipped with a coke oven door.

In the horizontal chamber coke ovens currently in use exclusively, the chamber walls running parallel to one another are equipped with heating flues in which the coke oven gases are combusted with air supply. Both vertical narrow top sides are closed by coke oven doors which must be opened each time the oven contents, i.e. coke cake, are to be extruded from the oven after the coking process has been completed. It can be done. In the case of coke oven doors known up to now, a door filler consisting of masonry rests on the inside, which projects into the area of one or more heating flues when the coke oven door is installed in a coke oven. In order to improve the gas discharge, this masonry filling is currently being replaced by a hollow body made exclusively of heat-resistant copper material. Furthermore, coke oven doors are already in use in which the individual plates are held in front of the door body at regular intervals via spacer pieces. The gas collection chamber formed in this way allows for an advantageous pressure relief in this region and a quick and uniform discharge of the resulting gas. The gases generated during the early stages of the coking process do not escape into the atmosphere in large quantities, thus significantly reducing environmental pollution. Furthermore, it is clear that the front coking plate improves a type of ironing effect, ie the carburization of the furnace top directly in contact with the area of the coking plate. Of course, the effect on the coking coal bed and thus on the furnace top that is acted upon by the coking plate is only slight and cannot be adjusted or adjusted. A further disadvantage is that such caulking plates are difficult to handle and can only be assembled and dismantled, especially at great expense. Even if the coking plates are divided appropriately with respect to the elongation of the material, assembly and disassembly are expensive, especially with a diameter of 6 m and a relatively high furnace door.

The object of the invention is to provide a coking plate and a coke oven door which can be easily assembled and dismantled and which can be well adapted to the respective requirements, through which the coke oven door can be It is an object of the present invention to construct a coke oven that provides reliable, desired and uniform coking of the top portion of the oven contents while maintaining a uniformly high coke production rate.

According to the invention, the coking heat is also supplied from both top sides, so that the entire area of the furnace top can be completely coked, so that even if the dimensions of the coke oven are unfavorable or the furnace is already in operation for a long time. During the course of the coking time, there is no longer any raw residual coke fraction. This makes it possible to use the entire charge economically in each case and to further reduce environmental pollution, especially if the coke is pressurized. It is also easily possible to supply coking heat from the top side. This is because the coking plate is suspended as an independent unit in front of the coke oven door, thus providing sufficient heat to the oven charge. By improving coking at the top of the furnace,
At the same time, an improvement in the coking of the entire furnace charge is achieved. This is because the gas generated in this region is preferably drawn off laterally and no longer passes through the entire furnace charge or through the coke cake.

According to the invention, the coking heat is supplied from the top of both furnaces to the furnace contents by heating the coking plates. In this case, the coking plate is heated not only by the discharged gas but also by the side radiation of the chamber walls and also by the side radiation emanating from the furnace contents or the coke cake. The gas discharged at the side is first guided along the walls in the coke oven, reaching a temperature of 600-700°C. The hot gas then enters a vertically arranged gas collection chamber and flows upwards through the collection chamber, imparting some of its heat to the caulking plate. According to calculations, in a 7 m high furnace equipped with a gas-heated coking plate, only the coking coal layer exposed and in contact with the approximately 20 cm thick coking plate will be coked. Ru.

In order to transfer as much heat carried by the gas to the caulking plate as possible, in the present invention, the generated gas is guided closely along the caulking plate over a predetermined length. be done. Guidance of this gas along the caulking plate is achieved by suitable intermediate structures, in particular suitably formed spacer pieces. In this case, the gas is guided in each case piecemeal directly into contact with the caulking plate and then again in the next step away from the caulking plate.

In order to make the gas heat available as fully as possible for the heating of the caulking plate, another embodiment according to the invention is to pass the generated gas through multiple swirling currents over the length of the lateral gas collection chambers. It is about making it happen. The generation of this vortex is advantageously created by means of a spacer piece, which on the one hand is also necessary to hold the caulking plate and to connect it to the door body. As already mentioned, coking from four sides requires continuous carburization at the top of the furnace, even when the coking plate is shifted from the conventional masonry packing. This makes this recarburization possible. By staggering the coking plates, the capacity of the coke oven is significantly increased. Moreover,
It increases by about 1.5 to 5%. This increases the production rate and the economy of the respective coking operation. This is because the maximum production rate can be achieved with the maximum reduction in energy usage.

A feature of the coke oven according to the invention is that the coke oven is equipped with coke plates made of individual, mutually overlapping and stiff members each releasably connected to a spacer piece. It is equipped with a coke oven door that closes the top side of the oven.

Such a caulking plate can be assembled quickly and without much effort and can be disassembled whenever necessary. In this case, it is particularly advantageous if each part of the caulking plate can be replaced or supplemented as required. When such a coke oven door is to be used in another coke oven, for example after being overhauled or after its dimensions have been modified, the individual shield members may be replaced with shield members having corresponding dimensions. Due to the overlapping arrangement of the shields, a tight seal is achieved for the furnace contents and at the same time a sufficient heat flow between the individual shields of the coking plate is ensured. Ru.

Reinforcing ribs are provided on the inner walls to stabilize the individual shield members. As a result, the individual stiffening elements are only connected approximately centrally with the spacer piece. These reinforcing ribs are provided as double T-shaped members or oriented parallel to the edges, depending on how they are joined together with the spacer strips. It's decided.

According to another embodiment of the invention, the shielding member is square in design and projects the associated spacer piece in the longitudinal direction of the door body, in each case the spacer piece on one top side and the spacer piece on the other top side. is placed on the nearest shield. In this way,
A kind of shell-like structure is formed that can accommodate the elongation or contraction caused by temperature fluctuations without any special configuration. The individual shielding elements can therefore be firmly connected to the spacer pieces, for example via screw connections. This reduces assembly work and increases structural stability. This is an advantage. This is because when removing or swinging the coke oven door to install it, it is inevitable that the door will hit the machine, the coke oven, or the oven frame. This collision is harmless for such structures. This is because the individual shielding elements are in each case connected to a spacer piece, that is to say to its shielding element holder. On the other top side of the insulation, this insulation always rests on the insulation that is connected to the spacer piece in the other region.

Another way of forming the shield member and connecting it to the door body is according to the present invention, in which the shield member has holes communicating with each other on one top side, and a vertically elongated shape with a notched edge on the other top side. The hole with a relatively large diameter is adapted to the collar of the plug fixed to the spacer piece, and the hole with a relatively small diameter and the longitudinal slit are adapted to the neck of the plug. The individual shielding elements can therefore easily be slid over plugs provided on the spacer pieces, in which case these shielding elements are also secured to each other in the manner of a flexible skin. Fit.
Even in the event of large temperature fluctuations, the individual stiffening elements of the coking plate are able to "breathe" and their seating on the spacer piece and on the coke oven door remains unchanged.

The spacer pieces are U for fixing the insulating layer according to the invention.
By comprising a U-shaped stiffening member holder that stands up vertically and has a flange directed toward the door leg, this spacer piece can be installed on the door body at the same time. Can be used to fix insulating layers. The upright holding element that acts on the gas flow and deflects it makes it possible to achieve the desired deflection of the gas flow, to create a vortex in it, and to thereby ensure a good transfer of gas heat to the caulking plate. do. Since the shielding member holder is U-shaped and is arranged with the side surfaces pointing downwards, the desired swirling effect and damming of the gas can be achieved in each case. This effect is
According to the invention, a further improvement is achieved in that the flexible member holder is fixed to the leg piece with grooves formed in the center and on both sides. The gas is therefore always forced in the direction of the caulking plate, is brought into a vortex, is moved against it in the direction of the caulking plate, and is caused to flow past it.

The formation of swirls and the improvement of the transmission of gas heat to the caulking plate are likewise achieved by shielding element holders, each designed as two angular elements mounted perpendicularly on the legs. Depending on the arrangement and design of this angle element, the gas flow or gas vortex is purposefully diverted in the direction of the caulking plate, thereby ensuring an excellent transmission of gas heat.

Other configurations of the shielding member holder and the spacer piece according to the present invention have the following points. In other words, the shielding element holder is designed as a piece of iron with parallel oriented side surfaces which are connected to the legs or the shielding elements, and which side surfaces are arranged offset. It is provided with a number of holes or rows of holes arranged at intervals and adapted to each other. Such a blank or shield holder or spacer piece is particularly suitable for applications in which the spacing between the caulking plate and the door body has to be changed from time to time. That is, when changing the spacing between the caulking plate and the door body, in such configurations, remove the screws or bolts installed in the matching holes, overlap the shingles or sides as selected, and then reinstall the screws or bolts. All that is required is to screw the bolt into the hole, thereby creating the desired spacing. In this case, it is appropriate to provide the holes in each case in a number of parallel rows of holes. This is because horizontal and vertical adjustment or adaptation of the caulking plate is then possible. The possibility of sliding in the vertical direction in particular makes it possible to adjust the distance of the lower device group, i.e. the last spacer piece, with respect to the furnace bottom, thereby making it possible to adjust the distance for the incoming gas to be larger or smaller. do.

Another possible configuration for changing the spacing between the caulking plate and the door body consists of tube pieces that can be inserted into one another and have different diameters, which at the free end are connected to the fixing bolt. This is achieved by providing matching holes for the. In this case, a tube piece with a small diameter is connected, for example, with a caulking plate, and a tube piece with a large diameter is connected with a door body. During assembly, the individual tube sections must be inserted into one another in such a way that they are then respectively held in position only by the introduction of a bolt. In this case, it is advantageous for the tube piece to be designed as a square piece, so that it is easier to align the holes during subsequent assembly and to facilitate handling.

In particular, simple assembly by temporarily placing the flexible member on a spacer piece is possible by using a reinforcing rib made of flat iron with an upright edge so that at least one side abuts against the flexible member holder. This is achieved by forming

Particularly simple handling and convenient assembly when the reinforcing ribs are formed as flat iron with suitable raised edges is achieved according to the invention as follows. That is, the spacer piece and the stiffener holder, which is designed as an angle piece, are provided with a square-shaped connecting bolt and an associated reinforcing rib with a hole corresponding to the connecting bolt. This constitutes a coking plate that is extremely mobile, so that the coke oven door or the caulking plate assembled from the individual stiffening parts can be used as long as the coke oven door is attached to or removed from the coke oven. The coke oven itself exhibits good safety and does not cause damage to the coke oven itself or to the oven door on the other hand. This limited flexibility also allows the individual sealing members to accommodate thermal expansion and corresponding thermal contraction.

Other possible configurations of the connection of the spacer pieces and the individual shielding elements are according to the invention as follows. That is, the U-shaped spacer piece is provided with a plug on its side facing the flexible member, the neck and collar of which correspond to holes or longitudinal slits in which they fit into one another. That is what we are doing. In this way, the individual shielding elements slide over or over this plug and are supported on their lower side by the plug located below it or by the plug of the spacer piece located below it. By suitably shaping the plug, overloading of the parts projecting beyond the shrinkage element is largely avoided.

The individual spacer pieces simultaneously serve to secure the insulation layer on the inside of the door body. Avoidance of contamination of the insulating layer and at the same time ease of assembly and disassembly is achieved by covering the insulating layer with a U-shaped plate on the side opposite the door body, which is held by the legs of the spacer pieces. It can be achieved by leaning. Advantageously, the plates are shorter than the stiffeners, are spaced apart from each other in the region of the spacer strips, are covered with legs and are held with play. This plate is therefore not connected either to the insulation layer, to the door body or to the leg. This plate can therefore also easily undergo length changes that occur due to temperature fluctuations.

The introduction of the coke oven door into the coke oven is conveniently carried out by giving the door body or the lower end of the coking plate a special shape. For this purpose, a shielding member holder or spacer piece provided at the lower end of the door body is formed in a U-shape and is fixed to the door body at its bottom with the side facing upwards or downwards, in this case the upper The side surfaces of the holder serve as flexible member holders, and the lower side surface stands upwardly at the end, and both side surfaces are connected to each other via a connecting web. The lower side with the raised tip of the edge facilitates the introduction, so that the door can actually be pushed into the coke oven while resting on this leg.
In this case, according to the invention, the intrusion of coke or coke coal into the free space of the U-shaped stiffener holder can be prevented by moving the stiffener corresponding to the lowermost U-shaped stiffener holder into the free space. It is possible to prevent this by forming it so that it protrudes from the formed side surface.

On the machine side of the coke oven, leveling rod openings are provided in the door body or coke oven door. In this case, the guide of this leveling rod is such that during the reciprocating movement of the leveling rod itself, coke coal does not penetrate into the gas collection groove. The gas collection groove is covered by the bottom of the leveling rod guide. In order to provide sufficient stability to this bottom part, according to the present invention, a holding arm which is releasably connected to the uppermost part of the door body on the machine side and a U-shaped gasket fixed thereto is provided. A leveling rod guide consisting of a guide plate covering the collection groove is formed as one structural unit. With this configuration, on the one hand, the uppermost shield of the caulking plate can also be assembled by screwing the holding frame, in which case this shield remains in the same state each time, and the guide plate or the individual shield can be assembled. Stabilize the caulking plate assembled from.

A particular advantage of the invention is that it ensures reliable coking at the top of the oven, with a concomitant improvement in the overall coking process and a reduction in emissions penetrating the coke oven door, especially in the region of the coke oven door. This is the method by which reduction of emissions in the coke cake as well as emissions by pressure unloading of the coke cake is achieved.
The easy-to-assemble connection of the caulking plate and the spacer strip or door body gives the coking plate assembled from the individual flexible parts a great range of movement, which is susceptible to thermal elongation and contraction. Allow. Furthermore, the loads that occur when the coke oven door is introduced into and removed from the coke oven are well accommodated or balanced. In this case, the upper and lower regions of the coke oven door are constructed in a particularly stable and movable manner.

The invention will be explained in detail below with reference to embodiments illustrated in the accompanying drawings.

FIG. 1 shows a coke oven with a coke oven door 1. FIG. The coke oven door 1 is inserted into the coke oven with its door body 2, and the oven formed between both coke oven walls 3 is sealed off from the outside world.

A caulking plate 6 is provided in front of the door body 2 and is held through spacer pieces 4 and 5. This caulking plate 6 consists of a large number of stiffening members 7, 8, 68, which are connected to each other and overlap each other.

On the one hand, the gas collection groove 9 is connected to the shield members 7, 8,
68 and on the other hand by the door body 2 and the coke oven wall 3. The door body 2 has an insulating layer 10
This insulating layer is fixed to the inner surface of the door body 2 via the leg pieces 11 of the spacer pieces 4 and 5. In the area between the individual legs 11, the insulating layer 10 is additionally covered with cover plates 49, 50, which protect the insulating layer 10 from contamination and facilitate assembly and disassembly. become.

The furnace contents 12 are held at a predetermined distance from the door body 2 via the caulking plate 6, and gas collection grooves 9 are formed behind the caulking plate 6, and each of the gas collection grooves is formed by a spacer piece 4. , 5 is divided into grooves 47 and 48. In this case, a vortex or desired guidance of the gas flow in the direction of the caulking plate 6 is possible.

The spacer pieces 4 and 5 connected to the leg piece 11 are screwed to the door body 2 via the leg piece 11 and retaining screws 51 and 52. Connecting bolts 59, 60 are embedded in the opposing ends of the spacer pieces, and the individual stiffening members 7, 8 are connected to the reinforcing ribs 14, 15 formed on the lower side via these connecting bolts. combined. For this purpose, reinforcing ribs 14,
15 is provided with correspondingly designed and oriented holes.

The reinforcing ribs 14, 15 formed on the lower surfaces 16 of the shielding members 7, 8 are provided, for example, in a double T-shape, and in this case, each of the vertical webs running in the center is formed as a horizontal web. The reinforcing ribs 14 and 15 are connected to each other.

FIG. 2 is a schematic representation of the furnace contents 12, illustrating the coking process, ie how the furnace contents 12 are heated from the longitudinal sides 97, 98 and simultaneously from the top side 99, 100. useful for.

3 and 4, the spacer piece 4 is shown in plan and side view with the upright angle members 64, 65 and the connecting bolts 59, 60 projecting at right angles therefrom. These connecting bolts 59 and 60 are provided so as to indicate the direction of the open deck when assembled. In this case, the individual shielding elements 7, 8, 68 are screwed onto the connecting bolts 59, 60, and a connection between these shielding elements and the spacer pieces is formed. Adequate lateral stability is provided by two connecting bolts 5 each
This can be achieved by providing 9 and 60. The angle members 64, 65 stand vertically on the leg 11 in such a way that the retaining screws 51, 52 can be easily installed. This is not prevented by forming flat irons that connect the ends of the legs to each other.

FIG. 5 shows another configuration of the shield member and the spacer piece. In this case, the caulking plate 6 consists of a number of stiffening members 7, 8. The individual spacer pieces 4, 5 consist of a leg piece 11, not an angle piece resting on it, but a U-shaped stiffener holder 19, 20. A reinforcing rib 14 formed on the upper top side 17 of the stiffeners 7, 8 is connected to the respective stiffener holder. The U-shaped shield holders 19, 20 stand symmetrically vertically on the leg 11 and are provided with flanges 21, 22 pointing in the direction of the door leg. Channels 47, 48 are therefore formed on its sides, through which the gas is guided. In FIG. 6, the U-shaped shield holders 19, 20 are clearly visible, but the shields 7, 8 are omitted in this case. The flexible member holders 19 and 20 are, for example, spacer pieces 4,
It is welded onto the leg piece 11 of 5. Holes are formed in the bottom 26 of the shielding member holders 19, 20, which correspond to the holes in the reinforcing ribs 14 and serve to screw the two parts together. Leg piece 11
are connected to the door body 2 via retaining screws 51, 52, the legs 11 simultaneously holding the cover plates 49, 50 which are spaced apart from each other in this region. In this case, the respective upper covering plate 49 is also fitted with retaining screws 51, 5 at its edges.
It's listed on 2.

The individual shield members 7, 8 are shown in FIG. In this case reinforcing ribs 1 formed on the lower side 16
4,15 are shown. These shield elements have a corresponding spacing from the respective shield edges in the region of the top sides 17, 18 and on the longitudinal sides. The individual reinforcing ribs are joined or welded together to provide rigidity in the corner joint.
In contrast to the reinforcing ribs 14, 15 according to FIG. 1, these reinforcing ribs 14, 15 are in this case square and double-T-shaped.

Details of the coke oven door shown in FIG. 8 are not shown. This drawing particularly clearly shows that the individual shielding elements 7, 8 or 7', 8' are arranged one on top of the other in a scale-like manner. In this case, the spacer pieces 4, 5 have a different configuration from the spacer pieces shown in the drawings described so far. In this case, the illustrated spacer pieces are designed to be variable in length, as will be explained in more detail below. The individual shield members 7, 8, 7', 8' are connected to plugs 29 formed on the spacer pieces 4, 5.

A large-capacity gas collection chamber is formed between the two.

individual stiffeners 7 to the spacer pieces 4, 5;
Fixing or holding of 8 was explained in FIGS. 9 and 10. As can be seen from FIG.
7 has a vertical slit 39 cut through the edge 35. The diameter of the hole 34 corresponds approximately to the collar 30 of the plug 29. On the other hand, the diameter of the hole 35 and the vertical slit 39 located above the plug 29 correspond approximately to the diameter of the neck 31 of the plug 29. When providing the shield members 7, 8, the shield member 7 is first slid over the plug 29, as can be seen in FIG. This is possible because the holes 34 are relatively large. The shield is then pulled downwards so that the wall of the hole 35 approximately abuts the neck 31 of the plug 29. Thereafter, the vertical slit 39 of the next shielding member 8 is simply slid on the neck 31, and both shielding members 7 and 8 support each other auxiliarily, and a desired position is formed in the front surface of the gas collection groove 9. A blind-like curtain is formed. If necessary, the plug 29 can be extended so that, for example, flexible members 7, 8 of different thicknesses can be used, or the flexible members can be pressed tightly against the spacer pieces. The configuration is not shown. color 3
As can be seen from the figure, the plug 29 with 0 does not have to be formed in a special shape. This is because the plug protrudes into the raw coke. It is therefore advantageous to form the plug 29 in a suitable shape. Reinforcement ribs 40, 4
1 and 42 are provided in a double T-shape on the inner wall 43 of the shield member 7, as shown in FIG. 10, and serve to stabilize the shield members 7, 8.

FIG. 11 shows another embodiment of the spacer pieces 4, 5. The coke oven door 1 or the door body 2 is here a tube 79, in which a coking plate 6 and a further tube section 80 are connected, in this case tube sections 79 and 8.
0 are formed so that they can be inserted into each other. When assembling the door body or changing the distance between the door body and the caulking plate, use one of the tube pieces 8 with a smaller diameter.
0 is introduced into and extracted from the other larger diameter tube piece 79. In this case, the fixing bolt 85 is inserted into the holes 82 and 84 formed in the free ends 81 and 83. The tube piece 79 is provided with a leg 86 on the side facing the door body 2 . Via this foot, a convenient connection with the door body 2 is achieved. In this case, the necessary insulating layer 10 is wrapped around the tube 79 and provided with suitable cutouts.

Similar to the spacer piece shown in FIG. 11, the distance between the door body and the caulking plate can be changed with the spacer piece shown in FIG. For this purpose, the spacer pieces 4, 5 consist, for example, of two U-shaped iron pieces, which are arranged facing each other with their respective sides 88, 89. The side surfaces 88, 89 have offset holes 90, 91 or corresponding rows of holes into which bolts or screws are inserted, thus forming the connection. Both U
The bottom parts 92, 93 of the letter-shaped spacer pieces serve for connection to the door body 2 or the caulking plate 6, respectively.

FIG. 12 shows a coke oven door with a coking plate located at the front, approximately in the central area. From the illustrated embodiment in which spacer pieces 4, 5 of a defined style are used, the shield members 7, 8
It can be clearly seen that each of them overlaps in the end region. In the illustrated embodiment, the retaining screw 5

The cover plates 49, 50 are formed with a shorter dimension than the shield member. These covering plates can therefore easily accommodate and be changed in length.

FIG. 13 shows the lower region of such a coke oven door with a coking plate 6.
The lower spacer piece 5 is designed as a type of U-shaped leg. This special leg is screwed to the door body 2 via the bottom 71. In this case the first

FIG. 14 shows the upper region of the coke oven door 1 with the leveling rod guide 54 and the leveling hole opening 55. This leveling rod guide 54 consists of a U-shaped guide plate 56 whose bottom 57 covers the gas collection line 9. The uppermost shield part 7 is pivotally mounted to the leveling rod guide part 54, and a support plate 66' is also pivotally mounted thereto. Therefore, they form one structural unit. Leveling rod guide part 5

In the region of the connection points of the caulking plate 6 and the shielding elements 7, 8, connection bolts 59, 60 are provided, which can be introduced into the holes of the reinforcing ribs 14. Two other coupling bolts 102, 103 are provided at a distance from this coupling position, and therefore the flexible members 7, 8,
Each of 7' and 8' can be suspended with respect to the door body 2 and the leg piece 11 at different intervals.

In addition, a retaining slot 104 is formed in the respective region of the reinforcing ribs 14, 15, into which a retaining member 105 shown in FIG. 16 can be slidably inserted. This retaining element 105 is additionally welded to one of the reinforcing ribs 14, 15 of the adjacent shield elements 7, 8, so that loss of these individual elements is avoided. Via this holding element 105, the strength of the stiffening element is achieved, especially in the edge region.
Therefore, the connection bolts 5 of the individual flexible members
9, 60; 102, 103 is avoided even under unfavorable circumstances. Additional security is achieved in that the holding element 105 is each welded on one side to a reinforcing rib 14, 15 and screwed on the other side to a corresponding reinforcing rib. This creates a permanent and effective connection that allows for easy assembly and disassembly. The holding elements 105 are designed as U-shaped beams and are introduced into the holding slots 104 of the respective adjacent shielding elements during assembly. As shown in FIG. 15, such a holding slit 10

In addition to 5, two reinforcing ribs 40, 40' are provided which run parallel to the longitudinal edges of the shield members 7, 8. These reinforcing ribs 40, 40' are spaced apart from each other, which spacing allows folding over the U-shaped flexible member holder 19.

The coke oven door 1, which is illustrated in detail in FIGS. 1 to 16, is provided with a sealing zone 101 surrounding the circumference.
This sealing zone serves to airtightly seal the interior of the coke oven against the outside world when the coke oven door 1 is in use.
