Definitions
- the invention relates to a wet quenching tower for the deletion of hot coke with a quenching chamber, with a scrubber above the quenching chamber for the application of firefighting water, placed on the quenching chamber fireplace and with at least one horizontally or at an oblique angle to the vertical arranged, vertically flow-through separator , which has a plurality of fins, each having a branch-free cross-section, wherein between each two adjacent fins flow paths are formed.
- Wet extinguishing towers are used to cool still hot coke directly after the coking process and to avoid burning off the hot coke. For this purpose, the coke is dropped from the oven opening in a fire truck and then brought with the fire truck to the wet extinguishing tower.
- the hot coke is sprayed with water with the help of the extinguishing spray, which immediately forms a very large amount of steam, which are also referred to as extinguishing swaths. Due to the sudden cooling and the increase in volume due to the evaporation of the water, large amounts of dust are generated and torn up with the extinguishing swaths.
- Dust particles due to a different size distribution and a different specific gravity also have different properties with respect to their separability.
- flow paths are provided which have a change in direction. The water droplets heavier to the air can not follow such a change in direction and strike down accordingly on the walls of the separator.
- special measures are provided in the known wet extinguishing towers, ie, for example, cause a turbulence of the flow at the separator.

- a complete cleaning is difficult.
- the Abscheid in terms of water droplets is still in need of improvement.
- DE 30 46 313 A1 discloses a wet quenching tower, in which the separating device is flowed through horizontally.
- the individual lamellae have in cross section a branch in the form of a fin, which forms a counter to the flow direction open catching chamber.
- Such a shape of the slats is not suitable for vertically effetströmbare Abscheid Roaden because then in the area of the branches, a cleaning and removal of depressed dust is very difficult.
- the present invention seeks to provide a wet quenching tower, which allows for a simple construction efficient separation of water droplets and is easy to clean.
- the object is achieved in that the flow paths formed between two slats change their direction several times.
- the flow paths have a simple, angular design that is essentially optimized for the separation of water droplets.
- an embodiment optimized for the separation of water droplets in which the flow paths change their direction at least twice.
- the slats may have a waveform with arcs or with several consecutive bends.
- the separation device can be operated in such a way that sufficient dust separation is achieved.
- the present invention takes into account the fact that the dust is deposited not only directly but also bound in the water droplets.
- the ascending extinguishing swaths are repeatedly, d. H. at least twice, deflected, the drops of water due to their inertia of the flow can not follow unrestricted.
- both the cross-sectional profile in the production of the separating device and the size distribution of the drops can be changed by an additional spraying of the extinguishing swaths and adapted to each other.
- An optimization of the droplet size is also possible during operation of the wet extinguishing tower by an adapted spraying.
- a control of the spraying can be done, for example, depending on a direct measurement of the drop size or indirectly from the determination of the emitted immissions.
- the separating device is arranged such that it flows through vertically. It should be noted that the deposited on the fins liquid drips down without further action down in the ascending extinguishing swaths and can be at least partially entrained again.
- the separator can be arranged exactly horizontal.
- An oblique arrangement can be used in particular to allow a lateral discharge of the condensate on the slats.
- the slats are expediently inclined so that along the individual slats, a slope is formed at which the condensate is discharged laterally.
- the flow paths are formed essentially of comparatively large, successive arcs, while the slats have an additional fine structuring in order to form channel-like formations along the slats.
- the slats along their cross section have a substantially constant thickness.
- Such slats can be produced, for example, readily by forming a sheet or a plastic sheet. Such a simple production also makes it possible to arrange the lamellae in the form of packages in a modular manner.
- branches that is, for example, fin-type branches or T-shaped branches at the ends
- branches are dispensed with.
- no sharp bends of the slats are provided at the inlet cross section and the outlet cross section of the flow paths, which overwhelm an increased production costs and a more complex cleaning.
- Particularly preferred in this context is an embodiment in which the ends of the slats stretch straight or substantially straight in the direction of flow. If the flow paths are free of branches, bends or the like, an approximately constant width is achieved along the entire course.
- H can be provided a Spülvorrichtu ng, which the separator from above, from below or
- the flushing device can be provided with appropriately aligned spray nozzles.
- a control device which is set up for a corresponding interval-type actuation of the spray device.
- simple wave or serrated shape of the slats simplified cleaning is possible.
- the lamellae can be shaped such that their entire surface is accessible during cleaning for a corresponding water film.
- the invention also provides a method for extinguishing coke with the load extinguishing tower described above, wherein hot coke from a coke oven, for example with a fire truck, the quenching chamber is supplied, wherein the hot coke with extinguishing water to form extinguishing swaths containing water vapor and dust particles , is cooled, wherein the rising in the chimney extinguishing swaddles are passed through the separator, wherein deposited in the separator by multiple deflection along the flow-rich water droplets with dust bound therein and wherein the separator is cleaned continuously or at intervals with the flushing device.
- the ascending extinguishing swaths above the extinguishing spray and before reaching the at least one separating device additionally sprayed with water to achieve an increase in the average droplet size, cooling the extinguishing swaths and thus increasing the condensation and an additional binding of dust particles in the extinguishing swaths.
- the spraying can be carried out in such a way that strict specifications with regard to particle emission are met.
- the wet quenching tower can in principle also have at least one additional separating device, which expediently also has fins which form flow paths with a plurality of changes in direction.

- Fig. 1 shows a wet extinguishing tower for the deletion of hot coke, which is introduced in the embodiment with a fire truck 1 in a quenching chamber 2. To cool the hot coke and burn off
- a spraying device 5 is provided, with which the rising extinguishing swaths are additionally sprayed with extinguishing water.
- This spraying device serves to further cool the extinguishing swaths and thus to achieve increased condensation.
- the average droplet size is increased, and thus the deposition in a subsequent direction of flow, ie above arranged deposition device 6 is facilitated.
- the additional spraying by means of the spraying device 5 also binds additional dust particles from the extinguishing swaths into liquid droplets. The dust particles are thus washed out by means of the spray device to a certain extent from the extinguishing swaths.
- the separator 6 is designed for a vertical flow and slightly tilted with respect to the horizontal plane.
- the exact orientation of the separating device 6 results from a comparative examination of FIGS. 1 and 2, wherein FIG. 2 shows a view rotated by 90 ° relative to FIG. 1.
- the separating device 6 comprises a multiplicity of parallel lamellae 7, wherein the lamellae 7 each have a branch-free cross section and wherein flow paths 8 are formed between each two adjacent lamellae 7.

- the shape of the lamellae 7 is shown by way of example in FIGS. 3a and 3b.
- the direction of the flow paths 8 formed between two lamellae 7 changes several times, wherein, according to FIG. 3 a, the lamellae 7 have a wave shape with at least two inflection points in cross-section. Due to the multiple deflection, the separation efficiency is increased in terms of drops, which due to their inertia can not follow the direction changes.
- FIGS. 3a and 3b agree that the flow paths 8 along their course in the vertical direction have an approximately constant cross-section, ie. have an approximately constant distance between the slats 7.
- the lamellae 7 according to the two embodiments of FIGS. 3a and 3b along their cross section have a constant thickness.
- the slats 7 shown can thus be produced in a particularly simple manner by forming a sheet or a plastic sheet. Even if the lamellae are formed by injection molding, the contour shown is particularly simple and therefore inexpensive to manufacture.
- the separation efficiency in the separation device 6 depends essentially on the size distribution of the drops. This size distribution can be adjusted by the additional spraying by means of the spray device 5 to a certain extent.
