Definitions

  • the invention relates to a device for burning contaminants contained in a media stream consisting of a housing with an inlet connector and an outlet connector, a heat exchanger and a burner device, which is formed from individual burners arranged distributed over the cross section of the media stream.
  • the housing consists of a cylindrical container, the media stream being passed via an inlet connection through axially aligned heat exchanger tubes arranged in the container, through an annular chamber equipped with a burner device and via a coaxial in the container stored high-speed pipe after the flow around the heat exchanger pipes is fed to the outlet port.
  • the cylindrical container is composed of at least three coaxially successive container sections.
  • the first container section contains the heat exchanger tubes extending over its length
  • the second container section is equipped with the burner device consisting of individual burners.
  • the third container section comprises the coaxially arranged high speed tube. With an end piece, this penetrates the burner device in the second container section and extends to the first container section.
  • the invention has for its object to provide a device of the type described in such a way that when using a commercially available heat exchanger with a rectangular cross-section, the media stream loaded with contaminants is aerodynamically optimal from the heat exchanger into the combustion chamber and the media stream freed from contaminants is also aerodynamically optimal from there can be removed via the heat exchanger.
  • the aligned arrangement of the inlet and outlet cross-section of the inlet or outlet connector creates the prerequisite for arranging a commercially available heat exchanger outside the housing, which, like the heat exchanger, is cuboid-shaped, directly on the connector.
  • the heat exchanger thus represents a structural unit which is compactly connected to the housing and, like the first container section of the known device, can be easily removed and removed for maintenance and repair purposes.
  • the ability to dismantle the housing is also ensured in the same way by dividing it into housing sections.
  • a second housing section, equipped with the outlet connection is connected to a first housing section equipped with the inlet connection piece, which receives the burner device, via which the media stream freed of contaminants is discharged via the heat exchanger.
  • the media flow thus has a rectangular flow cross-section, the individual burners of the burner device being arranged distributed over the cross-section of the first housing section.
  • the flow conditions of the media flow are therefore ideally solved in the device according to the invention using an inexpensive heat exchanger as in the device known from DE 44 14 875 C1, which requires complex ring-shaped heat exchanger tube bundles inside the housing due to a coaxial passage of the media flow.
  • the burner device is followed by a catalyst device extending over its cross section in the flow direction of the media stream.
  • honeycomb-shaped catalyst device is favored by the fact that there is a rectangular flow cross section and the mean flow rate in the burner device can be reduced considerably by the individual burners.
  • the individual burners which are operated in a manner known per se with a swirl superimposition, make it possible to reduce the average speed of the media flow at the treatment temperature to approximately 5 m / s.
  • the length of the section of the first housing section immediately following the burner device depends on the residence time of the media flow, which is necessary to ensure complete combustion of the contaminants. Due to the reduced speed of the media flow in connection with the more intensive effect of the individual burners, the overall length of the housing can also be considerably shortened with an additionally integrated catalytic converter.
  • honeycomb-shaped or bulk catalysts with a uniform temperature distribution across the cross-section can be arranged at a distance of 8 - 150 cm after the individual burners without being damaged by their heat.
  • the housing can be made particularly compact if the first housing section and the second housing section each have a rectangular cross section and a common longitudinal wall.
  • a compensator that compensates for different thermal expansions is arranged between the inlet connector and / or the outlet connector and the first or second housing section.
  • a further embodiment of the invention provides to provide a guide device that compares the media flow in a transition area from the first housing section to the second housing section.
  • the guide device preferably consists of lamellae which are arcuate in cross section or a perforated plate, the free perforated area of which is between 20% and 40% of the cross section of the first housing section.
  • the device comprises a cuboid housing 1 and a schematically illustrated, also cuboidal heat exchanger 2, which is designed as a conventional counterflow plate heat exchanger.
  • the housing 1 is divided into a first housing section 3 and a second housing section 4, the two housing sections 3 and 4 having a common longitudinal wall 5 which extends essentially over their length and are connected to one another via perforations of a perforated plate 6, which in the direction of flow of a media stream End of a housing section 3 and the beginning of the housing section 4 defined.
  • an inlet connector 7 and at the end of the housing section 4, an outlet connector 8 is provided.
  • a compensator 10 is interposed between an outlet cross section of the housing section 4 and an inlet cross section of the outlet connector 8 for the purpose of compensating for expansion between the two housing sections 3 and 4 and the inlet and outlet connectors 7 and 8.
  • the cuboidal heat exchanger 2 can be connected compactly to the housing 1.
  • Individual burners 11, which form a burner device, are arranged in the housing section 3 distributed over its cross section.
  • the individual burners 11 are held in a rectangular plate 12 adapted to the cross section of the housing section 3 and, as shown in FIG. 3, comprise connecting pieces 14 equipped with metal blades 13 which sit in the plate 12.
  • the media flow reaches the flame area of the individual burners 11 via the connecting pieces 14 with intensive swirling.
  • gas-permeable - e.g., extending over the cross section of the housing section 3 - honeycomb-shaped catalysts 17 are arranged, so that the device allows a catalytic treatment in addition to a thermal treatment of a media stream loaded with contaminants.
