Definitions
- the invention relates to a carrier matrix according to the preamble of patent claim 1.
- Catalyst bodies produced in corrugated strips provide an increase in the turbulence within the individual flow channels delimited by the smooth metal foils, but that in the radial direction almost no gas equalization can follow, but this is also desirable with regard to the utilization of the catalyst material. It has therefore already been proposed (DE-C-33 47 086.3) to form metal foils to be stacked directly in the manner of turbulence plates, as are used in heat exchangers. Such types have certain disadvantages in terms of manufacturing technology.
- the invention is therefore based on the object of avoiding these disadvantages and of creating a support matrix of the type mentioned at the outset which permits good utilization of the catalyst material with a simple production method.
- the characterizing features of claim 1 are provided in a carrier body of the type mentioned.
- the new foils can be stacked on top of one another in a simple manner without having to take into account the shape of the corrugations or the profile of the corrugations.
- the new film is excellently suited for the production of wound carrier matrices because the continuous smooth metal strip can absorb the tensile stress used during winding, and the corrugated strip that is also continuously adjacent to the smooth metal strip with offset corrugated sections because of its continuous arrangement over the entire width of the smooth strip but also cannot be deformed and undesirably deformed during the winding process.
- Corrugated metal strips of the type listed in claim 1 have a high intrinsic stability.
- the corrugated sections have corrugations with a trapezoidal cross section, which is in each case such that the smaller of the two parallel sides of the trapezoid each form the sides closed by the corrugated strip and the larger sides form the open sides of the corrugated strip.
- This trapezoidal cross section results in an extremely good stability of the corrugated tape, which is important when winding the matrix.
- a smooth metal foil 1 is shown, which consists for example of a thin steel sheet.
- This metal foil 1 is provided at certain intervals with openings 2, which can be stamped, for example.
- the openings 2 shown are rectangular. Of course, differently shaped openings, for example round openings, can also be provided.
- a metal strip Adjacent to the smooth metal foil 1, a metal strip, for example made of the same material but formed as a corrugated strip 3, is provided, which also consists of a there is only one continuous sheet metal strip, which, however, has been passed, for example, through a pair of rollers provided with projections and recesses, so that the embossments and incisions occur which are clear in FIG. 1.
- the corrugated strip 3 consists of a plurality of partial corrugated strips 3a, 3b, 3c etc. which are arranged one behind the other in the flow direction 4 and run transversely to the flow direction 4, and which are each designed identically to one another, but each about a quarter of the wavelength a transversely to Flow direction are offset from each other.
- each corrugated tape 3 is enclosed on both sides after a winding process by a smooth tape 1, so that thereby the aforementioned closed flow channels 5 are formed, but from layer to layer or from winding to winding over the openings 2 are also interconnected.
- the corrugated sections 3a, 3b, 3c which are firmly attached to one another, each have a trapezoidal cross-section, the smaller side 7 of the trapezoid each having the closed part of the corrugated strip and the larger side 8 of the two parallel sides of the trapezoid forms the open side of the corrugated tape.
- This leads to the fact that the smooth band 1 and the corrugated band 3 are particularly well suited for the production of a carrier matrix by winding, as shown in FIG. 2.
- a wound carrier matrix can be produced in a particularly simple manner with the two films shown in FIG. 1. It can then be soldered in a manner known per se and then coated with catalyst material. The wound foils are, likewise in a known manner, pushed into a tubular housing with a circular or oval cross section before the soldering process.
- the film shown in FIG. 1 is stacked on top of one another, it is of course also possible to produce rectangular carrier bodies.
