Definitions
- the invention relates to a coke oven door with a circumferential gas channel and membrane.
- Such a door is known from WO 01/30939 A2.
- the gas duct on the coke oven door creates a sealing system to avoid emissions and air ingress into the coke oven chamber, which reliably prevents both the escape of raw gases from the coke oven chamber and the air entry into the coke oven chamber.
- DE 41 03 504 C2 discloses a coke oven door in which a membrane with springs is pressed against the chamber frame.
- the problem with this arrangement is that the membrane must have a sufficient material thickness to be able to absorb the contact forces, ie the membrane must have high mechanical strength. sen. The membrane must not be damaged or destroyed during cleaning processes. On the other hand, the membrane must have sufficient deflection in the elastic range.
- the invention has for its object to provide a coke oven door with a circumferential gas channel, the sealing strips have such a large spring travel that the gas channel can adapt to all deformations taking place, so that a complete seal is guaranteed at all times.
- the sealing system on existing coke oven doors should be retrofittable even in tight spaces.
- the spring travel for pressing the gas duct should be as large as possible and its contact pressure in the longitudinal direction should be as uniform as possible
- the springs should act on the gas duct in such a way that the contact pressure of the outer door sealing strip is greater than or at least equal to the contact pressure on the inner door sealing strip there is.
- the seal between the gas duct and the coke oven door is ensured by a membrane which has such a large deflection capacity and at the same time sufficient mechanical strength to adapt to all deformations.
- the gas duct must be designed to be flexible in such a way that the contact pressure of the outer door sealing strip of the gas duct is approximately the same at each contact point.
- the sealing according to the invention can be carried out with all sealing systems known from the prior art. Thanks to the membrane with its high level of deflection, a better seal is guaranteed even with conventional sealing systems.
- the seal according to the invention makes it possible to compensate for all deformations of the chamber frame and also the coke oven door, so that a complete seal is guaranteed at all times.
- the sealing system also has the advantages named in WO 01/30939 A2, i.e. a gas pressure equalization between the gas channel and the coke oven chamber and thereby a reduction in the raw gas pressure that prevails on the outer sealing strip.
- the membrane consists of at least two layers.
- This embodiment has the advantage that the bending capacity of the membrane is improved in the elastic range compared to a membrane that has the same total material thickness. Due to the elastic behavior of the membrane, the membrane returns to the starting position when the contact pressure is reduced by the spring element.
- the membrane according to an embodiment of the invention is sandwiched from several materials.
- the membrane plate arranged towards the gas channel can be designed to be corrosion-resistant, while the middle membrane plate assumes the spring action (eg spring steel) and the upper one increases the spring pressure.
- the membrane consists of two 731 plates.
- the individual sheets have a higher elasticity than a single sheet, the wall thickness of which corresponds to the wall thickness of the two sheets and can shift against one another when deformed by the spring pressure.
- the membrane can also be designed in composite construction.
- the two sheets are connected to one another in the sense of a composite system. This can e.g. by webs or also by other materials, e.g. Plastics and / or adhesives are made.
- the tar produced in the coking plant can also be used for these composite construction methods.
- the individual sheets of the membrane can have a different material thickness.
- the membrane's bending behavior can be varied over a wide range and optimally adapted to the respective requirements.
- the individual sheets of the membrane can even be made with a material thickness in the tenths of a millimeter range.
- the membrane consists of many individual layers that can move against each other. This creates sliding planes on the contact surfaces of the individual layers. The membrane thus becomes more flexible overall and has a larger elastic range. This allows a larger spring travel.
- This embodiment has the advantage that any damage to the individual membrane sheets is automatically sealed due to the adhesive effect of the condensates (tar).
- At least one sheet of the membrane is designed as a spring.
- the membrane contributes to the contact pressure of the spring elements.
- the sheets forming the membrane can also be formed as molded parts. Any embodiments of springs or membrane sheets known from the prior art are possible.
- the membrane according to the invention can be combined with all spring elements known from the prior art. Due to its large deflection behavior, it adapts to all specified spring travel.
- the membrane is also possible to design the membrane as a spring element. All you have to do is spring or one sheet of the membrane.
- the spring element consists of a plurality of leaf springs arranged one above the other, which are jointly attached to the door plate above the membrane and press on the gas channel.
- the leaf springs are designed as individual springs in segments so that the sealing edges can better adapt to the deformations.
- the pressure ram can e.g. can be pressed against the gas duct by disc springs, coil springs or also hydraulically / pneumatically.
- a further possibility of exerting a contact pressure on the gas duct is to resiliently attach a spring plate to the door plate.
- the spring plate itself can also be designed as a rigid element with low elastic properties and the actual travel can be mainly caused by the resilient bracket.
- the resilient bracket can, for. B. by disc springs that are clamped on a screw. Another possibility is the attachment of a spring element on a spring rod. It is also possible to design a spring element in such a way that it takes over the spring function of the plate springs or the spring rod. This design has the advantage that only a single spring component that can perform both spring functions has to be manufactured.
- the spring travel is composed of the spring travel of the spring element and the spring travel which results from the resilient mounting of the spring element.
- the diaphragm must be designed in such a way that the diaphragm can follow this travel.
- the membrane must also have such a large spring action that it springs back into its starting position. Of course, this applies to all spring components of the spring system.
- any contact pressure with any distribution and any spring characteristic i.e. any different or identical pressures can be provided on the outer and inner sealing strips of the gas duct.
- any different leaf springs can be combined with one another in such a way that the spring effect increases with increasing spring travel: this can be adjusted either by a different shape or length of the leaf springs or by providing distances from the respective point of application of the spring.
- the springs can have a desired adjustable preload due to different clamping.
- the springs can also be designed in composite construction. All known techniques can be used. Since the requirements for the composite construction of the diaphragms and springs are the same in terms of flexibility, the composite construction can be used for both the diaphragm and the spring elements.
- the composite construction can also be carried out in such a way that channels are created between the individual elements of the springs or the membrane.
- the channels can be designed as cooling or heating channels by introducing an appropriate medium. It is also possible to design the channels with an insulating material as an insulating layer.
- the gas duct must be designed in such a way that it can adapt to the unevenness and deformations of the chamber frame.
- the gas channel must have such a large cross section that the raw gas can be removed without pressure build-up.
- the gas duct is designed with an inner and an outer sealing strip.
- the gas duct In the area of door sealing, the gas duct must be as flexible as possible. This is e.g. B. possible in that the wall of the gas channel is made in the material of the door seal in a lesser material thickness or by indentations or bends, thereby increasing the ability to bend in this area.
- the gas channel can also consist of appropriately shaped elements of the membrane or the springs (leaf springs).
- the corners of the door represent a particular problem for the tightness of coke oven doors.
- the individual layers of the membrane are made in one piece for the upper and lower area, so that each has a U-shape.
- the membrane that seals the long sides of the coke oven door is fitted to this U-shape. This arrangement ensures the permanent gas-tightness of the membrane, since the seams are arranged outside the heavily loaded corner area.
- the individual membrane parts can be connected by welding. Due to the structure of the membrane from individual layers, the membrane can be connected in such a way that the individual layers are offset with their seams. Due to the overlap of the individual membrane layers in this area, gas tightness is achieved.
- the individual membrane sheets In order for the membrane to have the same material thickness in this connection area, the individual membrane sheets must be arranged “in a butt joint”. This butt joint can be carried out in different ways. In the simplest case, the individual membrane layers are cut at right angles and arranged in an abutting manner. It is also It is possible to have the individual membrane sheets meet diagonally. The edges of the individual membrane sheets can also be beveled so that there is a so-called sharpened joint. The diagonal design of the joint edges increases the length of the sealing channels, while the bevel (sharpening) increases Membrane layers the sealing surface is enlarged.
- the individual membrane layers must overlap in the material. rial thickness are mutually reduced such that the two overlapping layers together give the layer thickness of the individual layer. This can e.g. B. by beveling (sharpening) or by appropriate millings (step formation).
- tar can also be used in the manufacture of the membrane as an adhesive and sealant for connecting the individual membrane layers.
- the individual membrane layers in the connection area can be arranged overlapping without further measures. It is sufficient to arrange the individual membrane sheets offset in the connection area.
- the profile of the gas channel rests on the chamber frame and does not take part in the spring deflection in the event of any deformation, there is little or no tension in this area.
- a miter can be provided in the area of the door corners. Since the weld seams are only exposed to low stresses in this area, any other type of connection can also be selected.
- the gas duct is also possible to design the gas duct as a plug connection in the corner area. A possible plug connection is shown in the drawing. The arrangement of plug connections can also be provided at any point in the gas channel.
- the sealing system according to the invention with membrane, gas channel and spring element is ideal for retrofitting leaky coke oven doors. All Koskofen doors on the market can be retrofitted.
- the diaphragm according to the invention with the spring element can also be used for retrofitting with all sealing systems known from the prior art.
- the size, shape, material selection and technical conception of the above-mentioned components as well as the components to be used according to the invention described in the exemplary embodiment are not subject to any special exceptional conditions, so that the selection criteria known in the field of application can be used without restriction.
