Definitions
- the invention relates to a steelworks converter, on the vessel hat of which a hat cooling is provided, which consists of a plurality of coolant guides which open into channel-like collectors, at least one cooling medium inlet and outlet being provided.
- DE 33 30 237 C2 discloses a metallurgical reaction vessel, in particular a steelworks converter, the vessel hat of which is provided with a so-called hat cooling.
- the hat cooling consists of meandering pipes, with several - in the present example, three pipes routed in parallel - conveying the coolant in the same direction.
- the individual essential pipes that run parallel to the central axis of the converter end in gutter sections on the top and bottom sides.
- a vessel hat cooling system which consists of a pipeline which is guided in a spiral around the converter hat.
- the invention has therefore set itself the goal of creating a drain for the coolant of the hat cooling with which the coolant in simple constructional means can be drained from the cooling system at a time without damaging the cooling elements due to excessive pressure due to impermissible vapor formation.
- a collecting pipe is provided in the area of the base of the cooling medium collector.
- the collector pipe is connected to the collector in such a way that the cooling medium reaches the collector through openings or via connecting pipes, the collector pipe having at least one closable drain.
- This arrangement according to the invention enables the coolant to drain out of the cooling elements of the hat cooling system particularly quickly in emergency situations.
- Hat cooling systems usually consist of meandering cooling elements. Due to this arrangement, emptying the cooling system is complex and takes a relatively long time, since for fluidic reasons the individual segments are not connected to one another or are only connected via connecting pipes which are deliberately kept small in diameter. However, the long-lasting draining of the coolant involves the risk of steam formation, which can lead to significant damage, especially in hot converters.
- the collecting line proposed according to the invention forms a self-contained ring on which any number of outlets are provided.
- the ring can be shut off by fittings in ring sections, so that there is the possibility of also individual segments in an emergency - e.g. in the event of damage - quickly let it idle alone.
- openings are provided as slots or bores through which the coolant enters the header.
- the entire open area of the openings is designed in a size which corresponds to up to 5 times the outlet area of the associated cooling medium outlet.
- the pipe sections connecting the individual converter hat segments are provided with compensators, so that stresses on the hat as well as on the collecting line are avoided.
- the collecting pipe is routed around the hat as a ring line outside the collector and connected to the collector via connecting pipes. In this embodiment, it is proposed to run a partial flow through the collecting pipe in order to provide fresh water here during operation.
- Figure 1 is a schematic of the hat cooling
- FIG. 1 a section of the converter vessel 11, namely the converter hat 12 including the end flange 15, is shown with segments 13 which have tubes 21 guided in a meandering manner.
- the tubes 21 open at the top in a header 23 and at the bottom in a header 22.
- a header 24 is provided in the header 22, in FIG. 1
- this manifold 24 is attached as a half pipe on the converter hat 12, lying within the collector 22. 1 a to 1 c, an outlet 27 is attached to the collecting tube 24 and can be shut off by shut-off elements 42.
- the collector pipe 24 provided in the collector 22 is connected between the segments via pipe sections 34.
- the collecting pipe 24 shown in FIG. 1 b is arranged outside the outer wall 28 and is connected to the collector 22 via connecting pipes 37.
- FIGS. 1a and 1c show a section through the converter hat 12 with a tube 21, the collector 22 and the inner collecting tube 24.
- the collecting pipe 24 is located outside the collector 22, the collecting pipe 24 being connected to the collector 22 via connecting pipes 37.
- a cooling medium outlet 26 is connected to the collector 22.
- a drain 27 is provided on both the internal and external manifolds 24 in FIGS. 1 a to 1 c, which can be shut off by a shut-off element 42.
- At least one open vent (29) is provided in the header collector (23).
- FIG. 2 shows in detail the collecting pipe 24, which is spaced in the base-side collector 22 at approximately the same distance from the wall 14 of the converter hat 12 and from the bottom of the outer wall 28 of the collector 22.
- the drain 27 is connected to the collecting pipe 24.
- a section through the collector 22 is shown with a collecting pipe 24 which has openings 31, in the lower part of the picture in the form of bores 33 and in the middle of FIG. 2 in the form of slots 32.
- the slots are arranged so that the flow of the cooling medium W is resisted on the way to the interior of the collecting tube 24, here as an opening wedge in the direction of the tube interior.
- the lower part of the picture shows pipe pieces 34 which are connected to the collector 22 via compensators 35. Furthermore, the pipe pieces 34 can be shut off by a shut-off device 41, here in the form of a three-way valve which is connected to the
- Coolant outlet 26 is connected.
- FIG. 3 shows the diagram of the segments 13 with the meandering tubes 21, which are connected to the header 23 on the head side and to the header 22 on the foot side.
- the collector 23 is connected to the cooling medium supply 25 and to the cooling medium outlet 26 and is also connected to the collecting pipe 24.
- the manifold 24 is connected to a water supply 36.
- the cooling medium supply 25 and the water supply 36 are via a changeover valve
- the cooling medium supply 25 with a pump 45 for the main flow that is to say about 90% of the amount of water
- Water supply 36 with a pump 46 for the secondary flow that is about 10% of the amount of water, and the cooling medium outlet 26 after its idling is used for ventilation of the other segments via the connecting piece 43.
