Definitions

  • the invention relates to a flame arrester for gas passage openings, in particular as pipe and detonation protection and for the final securing of containers from essentially flat sheet metal strips arranged at a predetermined distance from one another.
  • the final securing of tanks in both Directions and the detonation prevention are provided to prevent flame out two spirally wound sheet metal strips through which the spiral flows exist, one of which is wavy or continuously oblique trapezoidal in the direction of flow is folded.
  • the second sheet metal strip is flat, which means that uniform gap width is guaranteed. But this results in one for the flame-retardant Effect adverse reduction in the heat exchange area and also the stability the spiral in the axial direction has to be made by additional cross-sectional components getting produced.
  • the core of the spiral winding presents considerable resistance for the gas flow, which is in the middle of the flow opening with the highest flow rate.
  • the same structure Flame barrier of EP 0 375 455 is due to the additional pot-like structure of the Volume resistance increased even further in normal operation. If to increase the Security level two or more of the described flame arresters connected in series , the disadvantages described are also multiplied.
  • DE-PS 241 925 is a sieve insert for pouring and pouring openings
  • Containers have become known in which a helical winding and of liquid parallel flowable sheet metal strip is present, the windings of which by projections are kept spaced for a precisely defined gap width.
  • This variant is but not suitable for a constant level flow through and flammable gases, as with the flame arrestors described above in their pipes and at to be secured containers. This ensures the stability of the metal strip cylindrical perforated plate would also disadvantage the flow resistance Significantly increase way.
  • EP 0 568 326 A1 describes an embodiment for a flame arrester Stack of stacked flat sheet metal plates described, the individual Plates by a spiral band or by other spacers in the predetermined Be kept apart. This means one over to extinguishing the flame additional material expenditure, again a lot of loss of space for heat exchange between gas and flame arrester, as well as a relatively high flow resistance for the Gas in normal operation and increased manufacturing costs due to a larger number of parts to be joined.
  • This object is achieved in that a number of separate, superimposed straight sheet metal strips in a flat configuration parallel to a die Axis of the plane containing the passage opening is provided, which sheet metal strips only by bulges every second one of the metal strips themselves in a predetermined one Distance from each other, which is the prescribed gap width for the respective gas, with the space between the sheet metal strips at least is free of other components in the area of the passage opening.
  • the flat metal strips despite the very high mechanical strength, especially in the direction of flow of the gas, i.e.
  • the disadvantage is more familiar Spirally wound, wheel-shaped flame barriers made of completely corrugated or trapezoidal bent sheet metal strips with a stabilizing star eliminated when connected in series due to the additional components to ensure the mechanical Strength also require a larger distance, namely because of this distance gas between the individual flame arresters is inadequate as a result Flame extinguishing effect of an upstream flame arrester is ignited again and so the ignition of the gas is not prevented. According to the status, this risk must the technology can be countered by arranging another flame arrester, what the effort, size and flow resistance in a disadvantageous way clearly increased.
  • the Bulges by known, preferably embossed bulges of the metal strips are educated themselves, although of course also afterwards on a completely flat level produced sheet metal strips applied and fixed bulges, at most from other materials could be provided.
  • the package consists of sheet metal strips alone Sheet metal strips with bulges are provided directly on top of each other and are the Bulges of sheet metal strips lying directly on top of one another offset from one another. This can be done with only one type of sheet metal strip, which is essential to the manufacture and storage simplified, compliance with the necessary for flame retardancy and ensures the greatest possible gap width for each gas to reduce the flow resistance become.
  • the mechanical strength without Impairment of the flowability and the good handling of the pact one above the other Sheet metal strip contributes the further feature of the invention that the longitudinal ends the sheet metal strip outside the passage opening at a defined distance from one another are kept fixed.
  • the longitudinal ends of the metal strips are cast in metal or plastic, welded or soldered.
  • Easiest to manufacture due to the possibility of using similar and equally sized parts is an embodiment in which the package of sheet metal strips one rectangular, preferably square, cross section. There is also the mechanical stability particularly good due to reinforced hold in the corners.
  • a more favorable ratio of flow area to material consumption can be achieved if the package of sheet metal strips has a round, preferably circular, cross section having.
  • a package of sheet metal strips at least one further passage wall for changing the Flow characteristic provided, which is designed as a perforated plate or wire mesh or is made of expanded metal.
  • the wide passage wall is evened out the flow and shape of any flame front so that no peaks in narrow limited areas arise, but a distribution over a larger area takes place so that the heat absorption capacity of the flame arrester is better utilized and no local overloads can occur. This also makes the transit time the flame front increased by the flame arrester. This is the passage of any flames safely prevented by the flame arrester according to the invention.
  • FIG. 1 shows a perspective view of a flame arrester with housing
  • Fig. 2 is a perspective
  • FIG. 3 is an enlarged view of a corrugated sheet metal strip of a flame arrester according to the invention in plan and side view
  • FIG. 4 is an illustration of another embodiment of a Laminated core for a flame arrester according to the invention.
  • One that can be inserted into a pipeline for a gas, for example between two flanges Housing 1 is on its transverse to the axis of the pipeline with one each Flow opening 2 provided, which preferably corresponds to the pipe cross section. Tapped holes 3 can be provided for inserting connecting screws.
  • the actual flame arrester is a cartridge 4 that can be handled separately and in one piece through a lateral, sealable opening that is oriented transversely to the pipeline 5 can be used in the housing 1.
  • the essentially flat metal strips come here 6, 6 'of the cartridge 4 to lie in the area of the flow opening 2, whereby they are oriented exactly in the direction of flow of the gas and thus the lowest possible Offer flow resistance.
  • substantially flat sheet metal strips 6, 6 'of the cartridge in an exactly predetermined Distance from each other, which of the specified specifications corresponds to the specified gap width for the respective gas.
  • a frame 7 is provided, which the mechanical stability and cohesion, i.e. the joint handling of the package of sheet metal strips 6 ensures.
  • the metal strips no matter which Execution, can be simple and inexpensive in any length - for principle Flame arrester diameters of any size - and also width - for a safe flame-extinguishing effect for every gas and for every requirement - so that for sufficient flame extinguishing effect with just one Sheet stack and thus the smallest possible dimensions can be guaranteed.
  • a very compact and small-sized flame arrester can be obtained if, as shown in FIG. 4, the sheet metal strips 6, 6 'to one of the typically round flow openings 2 corresponding round configuration can be put together. That can for example by cutting into the desired shape of initially the same length Sheet strips 6, 6 'can be reached after assembling them into a package. It is it is particularly advantageous if the ends of the metal strips 6, 6 'at the desired distance are fixed by pouring into metal or plastic 9. That can of course be done at any shape of the cartridge 4 may be provided.
  • the inner edge of this metal or Plastic frame advantageously corresponds to the edge of the flow opening 2 of the Housing and is normally (only omitted in Fig. 4 for clarity of illustration) covered by the frame 7 of the cartridge 4.
  • the 4 sheet metal strips 6 ' provided with bulges 8, the simplicity and clarity of the illustration but not shown.
  • cartridges 4 can of course also be directly adjacent to one another in a housing 1 inserted and replaced individually, for example for cleaning, without gaps in which the gas can ignite again.
  • other projections can also be provided, for example on Flat sheet metal strips 6, 6 'additionally applied material, preferably metal points.
