Definitions

  • the invention relates to a method for weakening a detonation in a container or piping system in which a starting detonation front divided and in an expansion room is merged again.
  • the invention further relates to a device for weakening a detonation in a container or piping system with a wall arrangement lying in the propagation path of the detonation front to divide and redirect the detonation front and with an expansion room in which the split detonation front again is merged.
  • the spread of an explosion of an ignitable gas mixture in a container or piping system can be used as a detonation or done as deflagration.
  • the flame propagation rate of Deflagrations are around 100 m / sec. and the combustion pressures in the direction of impact at up to 10 bar (at an outlet pressure the mixtures of 1 bar), while in the case of detonations flame propagation speeds of several 1,000 m / sec. and pressures can occur in the direction of impact of up to 100 bar.
  • detonation brakes are often or “detonation bumper” combined with a flame arrester, which has a large number of narrow and long gaps, in to whom the flame is cooled so much that it goes out is coming.
  • a detonation device consisting of a detonation brake and a flame arrester is known from DE-PS 1 192 980.
  • the propagating detonation front through a pipeline in the known device by the convex outside of a divided circular cylindrical wall and gets into a Expansion room with an enlarged one compared to the pipeline Volume.
  • the split detonation front can only take several Redirections against the flame arrester run in one Outlet connector is attached, which is 90 ° relative to the pipeline is angled, in which the detonation originally spreads Has.
  • the multiple redirections are required that a second semicircular cylindrical wall with a smaller one Diameter is provided, the mutually pointing fine wall pieces are arranged overlapping one another and thereby one Form a kind of labyrinth.
  • a similar device is known from DE-A 934 574 and DE-A 937 879.
  • the flame arrester is located in a 90 ° angle to the pipe Support.
  • a tapered nozzle is provided, which is a widening nozzle at a distance opposite.
  • At the edge of the tank there is a curved return line is directed back to the pipeline.
  • the main stream of incoming Gas flow flows through the tapered nozzle and produces it at the outlet Nozzle that is sucked away by the gases from the flame arrester should.
  • the main flow through the opposite nozzle is through the Return line led back and impinges there on a bypass of the explosion pressure starting, which flows laterally into the return line before entering the nozzle.
  • the device is used to protect against explosions and is not for use with detonations starting at significantly higher energy and speed are suitable.
  • the invention is therefore based on the object of a method and a device specify by which the attenuation of a detonation in a container or Piping system can be improved.
  • This object is achieved according to the invention with a method of the type mentioned at the outset solved by dividing the detonation front into a main front and there is a much smaller secondary front and that the main front with a longer term is directed into the expansion space, so that when the Main front in the expansion space of these combustion gases contains the side front.
  • the solution according to the invention is based on the fact that a preferred smaller part of the detonation front as a side front in the expansion space is directed and burns there, preferably in the form of a deflagration, so that the The main front essentially finds exhaust gases when entering the expansion space, which hinders the propagation of the detonation, making it regular disintegrates. This is ensured if the running time of the main front is relative to the secondary front is dimensioned so that the secondary front in the expansion space is already complete has decayed when the main front enters the expansion space.
  • the method according to the invention can be used in all container or pipe systems use to destroy or at least mitigate detonations.
  • the improved effect of the detonation attenuation according to the invention causes the flame arrester to have less narrow and / or few long flames must have an extinguishing column so that the one caused by the flame arrester Pressure drop for normal operating conditions is reduced.
  • the method according to the invention is particularly effective when the secondary front in the part of the expansion space on the outlet side, that is, for example, until short in front of a flame arrester located there, before entering the expansion room can. This caused the opposite front to burn off and enter the main front into the expansion chamber leads to an even improved and yet safer detonation mitigation.
  • a device of the beginning which functions according to the method according to the invention mentioned type is characterized in that the first route for the main front and a second line for a secondary front of the detonation front forms, the total cross section of the first conduction path being substantially larger is dimensioned as the total cross-section of the second route and the route are that the main front compared to the secondary front is delayed in the expansion space entry.
  • the overall cross section of the first conduction path is preferred at least four times the total cross-section of the second route.
  • the second route is in one preferred embodiment of at least one opening or at least one Line piece formed, the diameter of each below the critical diameter lies.
  • critical diameter is based on the knowledge that below a certain diameter of a pipe section butt front and flame front can no longer advance together and are therefore separated. Explanations of the term "critical pipe diameter” can be found in the article by Lee, J.H.S. Dynamic Parameters of Gaseous Detonations, Ann.Rev.Fluid.Mech. 16 (1984), pages 311 to 336.
  • the expansion space may be the most the wall arrangement in terms of flow through another end Flame arrester must be completed with flame-extinguishing columns.
  • the unnecessarily long delays avoids the main front, it is expedient if the second route the direct passage of the secondary front into the Expansion space allowed essentially without redirection. This is Particularly useful if the level has already been undershot the critical diameter for a flame front separation and shock front is taken care of, so that energy-consuming deflections are no longer required for the secondary front. Because the side front progresses essentially without delay, is that for the Main delay minimized required delay.
  • the second route can be in a simple embodiment by at least one in the direction of propagation of the detonation front lying opening of the wall arrangement can be formed.
  • the second route is through at least one in the direction of propagation the line section lying on the detonation front educated.
  • the line piece can expediently shortly before Flame arrest ends to counteract the burning of the Flame of the side front and the entry of the main front into the expansion space to ensure. With one in an angled Pipe piece arranged flame arrester, the line piece is expedient bent accordingly.
  • the wall arrangement of the The device according to the invention can in a manner known per se have circular cylindrical wall section which the Detonation front divided into two main fronts and redirected and the at least one opening or a line piece for the passage has the secondary front.
  • the Wall arrangement comprising a starting detonation front cup-shaped wall, in the bottom of which there is at least one opening or a line section as a second line path for the passage the secondary front is located, the first route on the Outside of the cylindrical sections of the cup-shaped wall runs.
  • the device shown in Figures 1 and 2 has a as Angle-shaped housing 1 with a possible Detonation input flange 2 and one to do so output flange 3 angled by 90 °.
  • Both Connection flanges 2,3 have walls 4,5, which face the inside of the housing 1 expand conically.
  • the wall 5 of the outlet flange 3 is located a level 6, on which a conventional flame arrester 7 is placed is.
  • the flame arrester 7 is made using an insert 8 of the housing 1 held in place
  • the insert 8 has one essentially circular cylindrical wall 9 through a transition piece 10 is expanded into a lower free edge 11, which at the Flame arrester 7 is present.
  • the circular cylindrical wall 9 faces the one on the input side Flange 2 opposite side a slot-shaped opening 12 on and is on the opposite end flange 3 Page completed by a flat plate 13.

  • the circular-cylindrical wall 9 also faces the inlet bottle 2 opposite area to the side of the opening 12 radial reinforcing ribs 16 which extend radially up to the height of the free edge 11 extend.
  • a small part of the starting detonation front passes through the Opening 15 as a side front and goes directly into the expansion room 17, just before the flame arrester 7.
  • the opening 15 thus forms a second line path on which a side front the detonation front reaches the expansion space 17.
  • the side front reaches the expansion space in front of the main fronts 17.
  • the secondary front disintegrates in expansion room 17 and burns as deflagration. If the main fronts in the Expansion space, this is - at least partially, preferably completely - filled with exhaust gases, so that the main fronts in the expansion space 17 no more or only flammable gases still find small amounts of it and insufficient energy can record for reproduction. The main fronts also fall apart therefore in the expansion space 17 before it goes to the flame arrester 7 reach.
  • the flame arrester 7 therefore only needs for the much less dangerous deflagrations can be designed have significantly less narrow and / or less long gaps. This creates a lower flow resistance and the Maintenance of flame arrester 7 made easier.
  • the insert 8 ' also forms the cover 14 of the longitudinal housing 1 the circular cylindrical wall 9 'has a diameter which corresponds to the outer diameter of the flame arrester 7.
  • Another circular cylindrical wall section is aligned on the side 18, which is concentric with the circular cylindrical wall 9 ', but is arranged with a smaller diameter.
