Definitions

  • the invention relates to a device for burning contaminants contained in a media stream.
  • the device consists of a cylindrical container with an inlet connection and an outlet connection for the media flow. This can be introduced into an annular chamber by means of radially extending bundles of heat exchanger tubes arranged inside the container. This surrounds a burner arranged on an inside face of the container and merges into a high-speed tube arranged coaxially with the burner.
  • the high-speed pipe opens into an annular space which surrounds the high-speed pipe.
  • the media flow can be fed from the annular space to the outlet connection via the heat exchanger tubes.
  • the end regions of the heat exchanger tubes on the inflow side are bent radially outward and are washed around by the heated media stream treated.
  • Such a device is known from DE 35 32 232 C2.
  • the heat exchanger tubes on the hot side of the device that is to say in the region of the burner, are bent inwards and inserted in a drum concentrically surrounding the burner, the result is that bent outwards Heat exchanger tubes the advantage that the tube ends on a much larger Circumferential surface can be arranged so that easier welding is achieved.
  • the welded ends can be at a considerably greater distance from one another, so that the jacket receiving the ends does not have to be an additional component such as a drum, but the inner wall of an outer annular space can be used as a fastening surface through which the carrier gas containing the oxidizable components can be used Entry opening is guided to the heat exchanger tubes.
  • the invention has for its object to propose a device of the type described in the introduction, in which all heat exchanger tubes have the same bending and compensating capacity, the force acting on each tube should be as low as possible, which is also a prerequisite for harmful vibration of pipes is avoided.
  • all radii of the bends and the connecting pieces between the bends of all heat exchanger tubes can be dimensioned the same, so that all heat exchanger tubes also have mutually matching compensation properties.
  • the connecting pieces between the arcs of the heat exchanger tubes are aligned tangentially to a circle, the center of which lies in the central axis of the container.
  • this embodiment enables the use of heat exchanger tubes with relatively long connecting pieces between the bends with the same device dimensions, so that the flexibility of the heat exchanger tubes can be increased considerably.
  • an embodiment of the invention provides that the end regions of the heat exchanger tubes are arranged in an end piece which is radially widened with respect to an outer annular chamber and to which the inlet connector is connected.
  • the device essentially consists of a cylindrical container 1, which is provided on the outside with a heat-insulating insulation 2.
  • the container 1 is near an end face 3 with a radially penetrating the container wall Provided inlet port 4, which opens into an annular prechamber 5. This is delimited on its side facing the center of the container by a circular disk 6, through which the inflow ends of heat exchanger tubes 7 are passed.
  • the heat exchanger tubes 7, which are arranged cylindrically near the wall of the container 1 and extend axially over a substantial part of the container length, are each provided with two bends 8 at the inflow-side end region, which form a Z- or S-shaped double bend 8-8 via a connecting piece 9.
  • the inflow-side end of a heat exchanger tube 7 lies on a larger radius than its outflow-side end, which penetrates a partition 10. This is arranged at a distance from an end face 11 of the container 1, whereby an annular chamber 12 is divided into which the outlet-side ends of the heat exchanger tubes 7 open.
  • the ends of the heat exchanger tubes 7 are welded rigidly on the inflow side to the circular disk 6, which in turn is rigidly arranged, and are also rigidly welded on the outflow side to the dividing wall 10, which is likewise rigidly arranged. Every change in length of the heat exchanger tubes 7 as a result of temperature changes is completely compensated for by a corresponding deformation of the S- or Z-shaped double bends 8-8.
  • the deformability of the double arches 8-8 is all the greater and can do so done more elastic, the greater the length of the connecting pieces 9.
  • these are preferably not completely radially oriented, but instead extend tangentially bent to form a circle, the center of which lies in the central axis of the container 1 and the diameter of which can correspond, for example, to approximately half the outer diameter of the container.
  • the annular space 12 encloses a burner 13, which is arranged concentrically with the end face 11 and opens into a coaxial high-speed tube 14. This in turn opens into a swirling chamber 15 which is delimited by the end face 3.
  • the swirl chamber 15 is adjoined in the exit plane of the high-speed tube 14 by an inner annular space 16, which encloses the high-speed tube 14 and extends over the most essential part of its length before it opens into an annular deflection space 17.
  • An outer annular space 18, which contains the heat exchanger tubes 7, is connected to this.
  • the outer annular space 18 extends with a radially widened end piece 19, in which the double bends 8-8 of the heat exchanger tubes 7 are accommodated, into an area which partially surrounds the swirl chamber 15.
  • an outlet connection 20 is connected radially, which likewise penetrates the container wall in the vicinity of the inlet connection 4 and is arranged parallel to the latter.
