Definitions

  • Catalytic post-burners for ovens, cookers or the like are used, for example in so-called self-cleaning ovens according to the pyrolytic principle, to oxidize the smoke to largely odorless and pollutant-free exhaust gases or the vapors produced in cooking, baking or roasting processes by oxidation or harmful to take disruptive effects.
  • it is essential to bring the catalytic assembly contained in a catalyst carrier, for example, to a working temperature at which a results in an optimized effect; this working temperature is usually higher than the temperature of the incoming smoke or fumes.
  • the heating element is a tubular heating element which has a metallic jacket in which a fleece wire lying in an insulating investment material is arranged, and in that the heating element has at least two helically arranged windings one behind the other in the axial afterburner flow direction.
  • the heating element is arranged in a separate annular space surrounding the actual catalyst.
  • a catalytic afterburner has become known from US Pat. No. 3,785,778, in which electrical heating wires engage in cells of a catalyst block which is coated with the catalytic. This requires a very complex catalyst carrier, which takes up a lot of space. A very large number of heating elements are required for uniform heating of the catalytic converter, which results in complex and fault-prone wiring.
  • the invention has for its object to provide a catalytic afterburner of the type mentioned in the preamble of claim 1, which ensures high efficiency with a simple and compact structure.
  • heating element is combined with the catalyst to form a unit.
  • the outer surface of the heating element expediently a tubular heater, can thereby be in direct contact with the catalyst, so that the preferably spherical, filled catalytic body is both by heat conduction and by gases around the heating element are heated indirectly by the heating element.
  • the immediate proximity of the surface of the heating element to the catalytic filling ensures that this surface is kept very effectively clean, so that deposits on the heating element are avoided despite the direct contact with the contaminants.
  • the heating element is essentially completely embedded in the catalytic filling or is arranged within its receiving space and is preferably distributed approximately uniformly at least over a cross section of this space, for example in such a way that adjacent cross sections of heating elements are free.
  • a filling of the receiving space with a grain, granules of any shape or the like is particularly suitable as a catalytic filling, so that the catalyst contained in a flowable bed can surround the heating element in a particularly narrow and evenly contacting manner.
  • the heating element is closer in cross section through the catalytic filling, in particular immediately adjacent, to its air inlet side than to its air outlet side, whereby that Heating element or the Heating elements can extend over a zone which corresponds to approximately one third of the distance between the air inlet side and the air outlet side, such that - measured in the air flow direction - the area free of heating elements is larger than the area in which heating elements or parts of a heating element are arranged.
  • the heating element forms the, preferably only, main heating of a circulating air heating of the baking chamber.
  • the catalytic afterburner according to the invention is particularly suitable for so-called convection bathtubs, in which the baking, cooking, thawing and similar processes are carried out with convection heating, which circulates the baking space with heated air, since in this case the heating element is provided both as an oven heater and as a catalyst heater and only a single heating element is required for this. Nevertheless, it is conceivable to provide the oven with additional heating elements, for example a grill heater, for special preparations.
  • the catalytic filling is arranged in a catalytic converter housing, which is preferably through at least one window-like air passage opening, which is larger than the grain size of the catalytic filling, is flat in processing and in the area of the passage opening on the inside Formed from a grid covered sheet metal or the like. Is formed. It is achieved with a stable design and easy manufacture of the catalyst that the mostly sharp edges of the grid on the inside of the Ge are covered and cannot cause injuries either during assembly or when cleaning the oven or the catalytic afterburner.
  • the efficiency of the catalyst can be significantly improved in a compact design in that the heating element and / or the catalyst are arranged in a ring around a central suction axis of the circulating air conveyor, so that both the catalyst and the heating element over a circumferential angle of at least almost 360 ° are effective and the axial extent of the catalyst and thus its depth can be kept very low.
  • the housing can be assembled in a simple manner from two ring parts, at least one of which is shell-shaped in cross section and which are placed against one another in an annular parting plane and / or with externally exposed flange edges, so that the housing can be easily filled and then, for example, by welding the flange edges close.
  • the other ring part can be formed by a simple hoop from a ring-shaped, flat, for example ladder-shaped band, the longitudinal edges of which form the flange edges and which have through openings.
  • narrow webs, approximately in the width direction, of the shaped strip, which in particular is ladder-shaped, are provided between the through-openings, which preferably extend from the shell bottom to the shell side walls in the respective shell-shaped ring part and over the ends of which the grid extends to the fastening on the inside of the respective ring part is sufficient.
  • the strip material can then be brought into its shell-shaped cross-sectional shape by embossing, rolling or the like, which is particularly simple if only the conductor webs need to be angled. Then or at the same time, the strip material thus profiled can be brought into the ring shape of the catalytic converter by means of steering rollers or the like, after which the two ring parts are connected to one another, including the catalytic filling.
  • a tubular heating element is particularly suitable as the heating element for the catalytic converter, which is preferably bent in a helical shape and the connection ends of which are in particular guided approximately radially outwards through the outer peripheral wall of the housing.
  • This heating element does not require any special attachment, since it is precisely secured in its position by the arrangement within the catalytic converter or by embedding it in the catalytic fill and can therefore be attached indirectly via the attachment of the catalytic converter.
  • the tubular heater which has a metallic jacket, in which a heating wire enclosed in an insulating investment material is arranged in a contact-free manner compared to this jacket, guarantees, on the one hand, with very good efficiency, direct heating of the catalytic filling through good heat-conducting contact on a large area, and on the other hand, a contact the catalytic fill or the catalyst with live parts of the heating element completely excluded.
  • the lattice can be formed in a simple manner by a fabric or the like, the lattice meshes or their boundaries expediently lying diagonally to the longitudinal direction of the shaped strip, so that the initially flat lattice strip can be converted very easily both into the described cross-sectional shape and into the ring shape .
  • the grid is expediently made of stainless steel.
  • the entire housing of the catalyst from wire.
  • Larger wire rings can bring together through the cross section of the overall toroidal housing individual wire struts, which are connected for example by spot welding, to form a housing in the form of a ring cage.
  • the wires assembled in this way can themselves form a grid which holds the catalytic bodies together, or can additionally be surrounded by a grid.
  • the heating element within the catalytic filling around a feed wheel of an axial fan with a radial outlet, so that the circulating air delivery device is directly surrounded by the air inlet side of the catalyst and itself result in very short flow paths. Since the heating element lies within the catalytic converter, the delivery wheel can extend radially very close to the air inlet side of the catalytic converter; in any case, it is expedient if the fan outlet runs directly through the catalytic converter.
  • a further improvement of the air circulation is achieved if the lleizelement and the catalyst are arranged between the back wall of the baking chamber and a suction and air guide orifice, through which the air is expediently sucked in axially and in the area of the outer edges of the cleaned and heated air circulation in a second air flow resigned.
  • the catalytic converter consists of annular lamellae coated with catalytic material, which are preferably profiled in a wave shape. They can be stacked to form an annular body, forming air channels between them, by stacking the lamellae, for example, which are corrugated at an angle to the radius, in the opposite position.
  • This relatively compact body ensures a large surface and best heat distribution from the inside out. If the tubular heating elements are arranged on the inside, the heat is distributed relatively evenly over the entire catalytic body.
  • the ring body can be enclosed between two cover rings. which are held together by connecting elements and which protrude somewhat over the inner circumference of the catalyst body.
