Definitions

  • the invention relates to a process for dry coke cooling in which the hot coke transported through a special bucket from the coke oven to the cooling chamber and is cooled in this, for which purpose the special bucket placed ühlschacht to K and then through a lock, the receiving of a closure spout and intermediate piece Housing exists, is emptied into the cooling shaft.
  • the invention also relates to a cooling shaft with an outlet funnel for the special bucket and with a lock arranged on the filler opening for carrying out the method, the lock consisting of an intermediate piece and closure receiving and adjoining the filler opening.
  • the so-called coke dry cooling leads to a considerable reduction in the environmental impact when quenching the red-hot coke.
  • the glowing coke is transported from the coke oven to the extinguishing device with the help of a special bucket.
  • the special bucket is closed during transport.
  • the special bucket is placed on the cooling shaft and the coke plunged into the cooling shaft by opening the bottom of the bucket.
  • a special lock is used to close the cooling shaft.
  • closable and lowerable closures for cooling shafts are known (DE-OS 3o o4 175.9), the closure including the rollers and an intermediate piece being arranged in a closed housing.
  • depressions are provided on the rails, into which rollers engage when the closure is closed.
  • the sealing effect of the closure is therefore dependent on additional measures.
  • the housing which is closed on all sides, requires a large amount of space and must be sealed to such an extent that the escape of gases is reliably prevented. If the gases are sucked out of the housing, it is disadvantageous that the housing has such a large volume.
  • rollers on which the closure is transported back and forth have to be adapted to the high requirements within the closed slide housing, which requires the use of special material.
  • the complex dimensions of the housing which result from the fact that the rollers and the rails and the actual closure and the intermediate piece are arranged within the housing, the closure and intermediate piece being pushed back and forth in the housing and raised will.
  • the invention is based on the object of making the method for coke cooling free of emissions even when the cooling shaft needs to be opened and of making the suction space required for this as small as possible.
  • the object is achieved according to the invention in that - after placing the special bucket, the intermediate piece and the closure move together and are covered and largely sealed against the atmosphere, and gases are released from this tightly enclosed space when the filler opening is opened.
  • the method according to the invention nevertheless offers the possibility of using a lock with the smallest possible volume the gases escaping when the cooling shaft is opened are safely collected and removed.
  • the filling process of the cooling shaft is thus free of emissions, which contributes to a further relief of the environment.
  • the closure and the intermediate piece can be moved back and forth and raised and lowered, the housing encapsulating these parts, ie the lock, being a very constant has a small volume.
  • the intermediate piece is encapsulated with a connection to the closure on the chassis.
  • Such encapsulation further limits the volume of the lock, but effective suction is nevertheless ensured in the period characterized by the emissions from the cooling shaft.
  • a cooling shaft is proposed in which the housing frame encapsulating the closure and intermediate piece is designed to be wholly or partially lockable together with the closure and intermediate piece.
  • Such a housing is adapted to the dimensions of the closure and intermediate piece without taking the displacement path into account, so that its volume is correspondingly small. Because of the smallest possible space, both the design effort and the subsequent operational effort with regard to the extraction are low.
  • the side walls of the housing frame which connect to the horizontal housing cover and bottom assigned to the outlet funnel and filling opening, are a closure assigned and intermediate piece and movable with these.
  • a housing acting as a lock is created, which has the smallest possible space, which is structurally simple to implement and which nevertheless effectively encapsulates the area around the fill opening when the closure is opened from the atmosphere.
  • the side walls of the intermediate piece and bogie-carrying chassis are assigned to the castors and the running rails to be recessed.
  • the rails and the rollers rolling on them are therefore outside the housing, are not used by the escaping gases and can be serviced particularly easily since they are easily accessible.
  • a sufficiently tight seal between the reciprocating side walls and the housing cover and the housing base can expediently be achieved in that the side walls and housing cover and housing base have angle irons on the mutually opposite edges. A larger contact and sealing surface is created via the angle iron. It is also possible to design the side walls and the housing cover and the housing base in the area of the edges so as to provide a contact or sealing surface.
  • the side walls on the edges of the housing cover and base facing these sliding sealing elements are pressure or other loading loads are not exposed, they are subject to little wear and tear and lead to an optimization of the seal if it should be found that the intake of ambient air is unfavorable or harmful.
  • a quick and uniform lifting of the closure in all areas and accordingly also a lowering after completion of the filling process is ensured according to the invention in that the closure can be raised and lowered via a spindle drive which is coupled to the displacement drive. It is particularly advantageous that such a spindle drive requires little space and can be arranged and designed according to the circumstances without requiring any significant design effort.
  • the coupling to the slide drive ensures a continuous, cyclical operation and prevents accidental damage to the lock by actuating the slide drive too early.
  • such drives can be designed so that they can be used for both functions one after the other.
  • the invention is characterized in particular by the fact that a method and a closure for cooling shafts of coke-dry cooling are created, by means of which an effective seal with the most favorable dimensions is provided. Because of the low overall height and the side walls of the housing which can be moved with the closure and the intermediate piece, this or the lock has a small volume, which at the same time leads to a reduction in operating costs.
  • the special design and arrangement of the side walls of the housing makes it possible to dispense with a protruding construction for encapsulating the lock and the intermediate piece.
  • the accessories of the chassis are outside the housing and are therefore largely protected against the escaping gases and heat.
  • Fig. 1 shows the upper region of a cooling shaft 1, which runs into the filling opening 2, against the closure 3 in the position shown in Fig. 1 is sealed above the atmosphere.
  • the closure 3 is raised and moved aside, the intermediate piece 4 simultaneously coming into the position of the closure 3 and thereby closing off the transition region between the discharge funnel 5 and the filling opening 2.
  • Suction ports 6 are indicated on the side of the discharge funnel 5. The gases flowing out when the cooling shaft opens are sucked in and sucked out via the suction nozzle 6, these being connected to the housing frame 9 encapsulating the closure 3 and the intermediate piece 4.
  • the cooling shaft 1 is provided with a lining 7 which extends up to the area of the filling opening 2.
  • the closure 3 itself is provided with appropriate insulation 8, because of the lightweight construction it is easy to handle.
  • Closure 3 and intermediate piece 4 are assigned to a common chassis 10, which has a plurality of, preferably four, rollers 11, 13, which in turn can roll on the rails 12, 14. As can be seen from FIGS. 1 and 2, the rollers 11, 13 are arranged outside the cover created over the side walls 15, 16, 17, 18.
  • the running rails 12, 14 themselves are not included in the area which is formed by the housing frame 9 in order to safely discharge the gases escaping when the closure 3 is opened and then to suction them off.
  • the structure of the chassis 10 is explained in more detail below with reference to FIG. 3.
  • Fig. 2 in which is cut transversely to the direction of travel of the chassis 10, illustrates how the upper edge 19 or the edges of the side walls 15, 16, 17, 18 are guided in or on the housing cover 20 or housing base 21.
  • the housing cover 2o is assigned to the outlet funnel 5, the housing base 21 to the cooling shaft 1 or the filling opening 2.
  • the side walls 15, 16, 17, 18 and the housing cover 20 and the housing base 21 form a housing which, owing to its small volume, can be kept free by suction with little effort.
  • the sucking in of external air into the housing is effectively prevented by said special design of the upper edge 19 or the edges of the side walls 15, 16, 17, 18.
  • Fig. 2 also makes it clear how exactly the closure 3 and the associated parts can be cut, because one can dispense with the inclusion of the rollers 11, 13 and other parts that are important for moving the closure 3 in the sealing that takes place over the side walls .
  • the running rails 12, 14 run parallel to the filling opening 2 below the actual closure 3 (FIG. 3).
  • the running rails 12, 14 are attached to the upper flange of the double-T profiles 24 and ensure that the running rolls 11, 13 roll off evenly.
  • the rails 12, 19 are arranged below the edge 22 of the filling opening 2 and parallel to the wall 23 thereof.
  • the device has a sufficient lifting height for the closure 3, so that an immersion seal 26 can be used, which ensures an optimal sealing of the cooling shaft in the closed state.
  • 3 edge plates 27 are arranged on the lower edge of the closure and are inserted with their free end 28 into the immersion seal 26.
  • the edge plate 27 is folded twice, so that a free edge 29 is formed, which lies exactly on the edge 22.
  • the above-mentioned optimal closure of the cooling shaft 1 takes place via this free edge 29 and the immersion seal 26.
  • a spindle drive 32 is used to raise and lower the closure 3, which in the example shown is combined with the displacement drive 33. Via the spindle drive 32, the spindles 34, 35 are actuated, which then raise the closure 3 fastened to the support strips 36 or into the seat, i.e. insert in the immersion seal 26.
  • the spindle drive 32 has the linkage 37, 38 in order to raise and lower the closure 3 simultaneously and evenly at all four corners.
  • Closure 3 and intermediate piece 4 are assigned to one and the same chassis 10, as has already been explained.
  • This chassis 1o consists of the longitudinal beams 4 0, where the rollers 11, 13 are secured, and on which the shutter 3 and the intermediate piece 4 is fixed from the transverse beams 41.
  • a roller protection 42 ensures, however, that the individual rollers 11, 13 are largely protected from being influenced by dirt and the like.
  • the closure 3 When the spindle drive 32 and the linkage 37, 38 are actuated, the closure 3 is first raised and then then pulled away from the filling opening 2 via the displacement drive 33. Since the closure 3 and the intermediate piece 4 are assigned to the same chassis 10, the intermediate piece is simultaneously pulled into this area when the closure 3 is moved This effectively covers this area when the coke falls.
  • the side walls 15, 16, 17, 18 in particular ensure safe discharge and suction of the gases flowing out of the filling opening 2, in each case interacting with the housing cover 2o arranged above or the housing base 21 arranged underneath, and the said one Form lock.
  • the housing base 21 is there. provided between the rails 12, 14 and in such a way that the lower edges of the side walls -15, 16, 17, 18. can grind tightly on it.
  • the inner walls 44 of the intermediate piece 4 are arranged obliquely inwards and downwards, so that a rectangular or square funnel 45 is formed. Uniform passage of the glowing coke is thus ensured.
  • the special design of the intermediate piece 4 and the connection between the intermediate piece 4 and the closure 3 is illustrated by FIG. 3.
