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 through a cylindrical bundle of heat exchanger tubes which is arranged in the interior of the container and extends axially. This surrounds a burner arranged on an inside face of the container and merges into a flue gas mixing tube arranged concentrically in the container.
  • the flue gas mixing tube opens into a main combustion chamber, at the end of which an annular space is provided, from which the media flow can be fed to the outlet connection via the heat exchanger tubes.
  • Such generally known devices are connected to an external conveying device in the form of a blower via pipelines to act on the media flow. Since flaps for alternative operation with or for admixing fresh air must always be arranged on the suction side of the blower that promotes the media flow, these flaps and mixing devices must also be arranged together with the blower or further away from the device.
  • blower and the additional components for adding fresh air are often all in one Building, while the incinerator itself is installed outside the building.
  • the invention has for its object to propose a combustion device of the type described above, which takes up less space overall and can be produced and operated more cost-effectively.
  • the inventive integration of the conveyor in the cylindrical container leads to numerous advantages over conventional devices. This eliminates the need for a separate installation space and space for the process fan. This also eliminates pipelines between the blower and the device and all associated costs in terms of structural changes, thermal insulation, inspection and maintenance. The arrangement of the conveyor on the end of the container opposite the burner also makes thermal insulation of the conveyor unnecessary.
  • the conveyor device does not require any sound insulation. Blow-out noises are also dampened by the large mass of the heat exchanger tubes on the pressure side of the conveyor. Furthermore, condensation cannot form as a result of heat losses on the wall parts of the conveying device, since both the fan and its suction line are optimally heated within the container. Even when operating with fresh air during start-up of the device and during stand-by operation, the conveyor and its suction line remain sufficiently heated, since sufficient radiant heat is available from the combustion chamber or can be generated to the required extent. For this reason, the device according to the invention has sufficient temperatures for rapid switching to exhaust gas operation even after long idle times in the exhaust gas area. Since the exhaust gas-carrying pipelines are under negative pressure right into the tank, leakage in these pipelines is also not dangerous or disruptive.
  • the device according to the invention can be preassembled by the manufacturer in a very compact form as a ready-to-use system. This can avoid considerable installation costs at the installation site of the device.
  • the conveyor device arranged inside the container consists of a radial fan, the drive of which is arranged on the outside of the container.
  • an impeller of the radial fan is surrounded by a housing, the outlet of which radially opens into the prechamber is formed by an annular gap.
  • the annular gap concentric with the prechamber is arranged in the vicinity of the relevant inside of the container with a sufficient radial distance from the inside of the prechamber, there is a highly effective mixing of the media stream blown into the prechamber.
  • the device consists essentially of a cylindrical container 1, which is provided on the outside with a heat and sound insulation 2.
  • the container 1 is provided in the vicinity of an end face 3 with an inlet connection 4 which penetrates radially through the container wall and is connected to the suction side of a radial blower 5 arranged concentrically on the end face.
  • An impeller 6 of the radial fan 5 is surrounded by a housing 7 which is provided with an annular gap 8. This opens into a prechamber 9, which is connected both to the inlet side of heat exchanger tubes 10, which are arranged cylindrically near the jacket of the container 1, and to the inlet side of a coaxial bypass 11.
  • the heat exchanger tubes 10 extend axially over the most essential part of the length of the container 1 and open into an annular chamber 12 which adjoins an end face 13 of the container 1.
  • the annular chamber 12 encloses a burner 14, which is arranged concentrically on the end face 13 and opens into a coaxial flue gas mixing tube 15.
  • the outlet cross section of the flue gas mixing tube 15 lies at an axial distance from an end wall 16 which separates the prechamber 9 from the remaining part of the container 1.
  • This is assigned a cylinder 17 which extends over the most essential part of the length of the flue gas mixing tube 15 and with it one Main combustion chamber 18 defined, which is connected in the vicinity of the inlet cross section of the flue gas mixing tube 15 with an annular space 19 which contains the heat exchanger tubes 10.
  • An outlet connection 20 is connected to the annular space 19, adjacent to the inlet connection 4.
  • the bypass 11 is equipped with a flap 21, with which the media flow conveyed via the radial fan 5 into the prechamber 9 is, to a greater or lesser extent, via the bypass 11 bypassing the heat exchanger tubes 10, the annular chamber 12 and the burner 14 Leaving from the flue gas mixing tube 15 and so far already pre-treated media stream can be admixed.
  • the bypass 11 consists of a nozzle 22 which is provided with radial openings 23 and is closed on the end face.
