Definitions

  • a flame arrester according to the invention of the type mentioned above is characterized in that the flame arrester is inserted into one of the cross-sectional area of the flame arrester corresponding opening of the wall and projects beyond the wall with at least one fifth of its height in the outdoor area.
  • the flame arrester according to the invention is thus not used in a stable enclosing cage, but only in an opening of the wall, and this only with a part of their height. This means that the thickness of the wall is definitely lower than the height of the flame barrier. With a standard wall thickness of 8 mm, therefore, the height of the flame arrester is at least 10 mm.
  • the fastener may also be formed by a known per se rib ring or a coarse mesh screen or fabric or a coarse mesh grid.
  • the winding of the smooth belt together with the corrugated belt is expediently carried out around a winding core designed as a sleeve.
  • a winding core designed as a sleeve.
  • the connecting element can then be used, so that it is ensured that no uncontrolled large gap widths are formed by the connecting element for the gas flowing through.
  • the effect of the heat radiation is thus supplemented by a cooling effect by means of a flowing inert gas.
  • the peripheral wall 19 of the flame arrester 8 can be formed by a thin metal sheet of at most 1 mm thickness and fixed to the flame arrester 8 by laser puncturing o. ⁇ .
  • FIG. 2 and 3 show a second embodiment of the invention with a wall 6 'which defines a vulnerable area 13 (FIG. FIG. 4 ) completes.
  • the wall 6 ' has a number of nine arranged on a circular path openings 7', in the snugly inserted flame arrestors 8, which protrude from the top 14 of the wall 6 'with a major part of its height and fixed with a rod-shaped second fastener 17 are, which are defined by a central bolt-shaped connecting element 18 on the bottom 10 of the wall 6 '.
  • the new flame arresters 8 are four other flame arresters 8 ', which are inserted into corresponding openings 7' of the wall 6 '.
  • the flame arresters 8 ' have a significantly smaller diameter than the flame arrestors 8.
  • the four flame arresters 8 ' are also arranged with their central connecting elements 18 on a circular path about a center of the wall 6' around.
  • the wall 6 ' is how FIG. 4 clarified, fastened with numerous screw 5 to an annular mounting flange 4 of a connection part 1.
  • FIGS. 5 to 7 illustrated third embodiment of the invention shows a connection part 1, the connection part 1 in FIG. 1 like.
  • the wall 6 is attached in the form of a plate to the connector part 1.
  • the wall 6 also has a circular central opening 7, in which a flame arrester 21 is inserted in the form of a circular cylinder, so that within the flame arrester 21, a circular cylindrical interior 22 results, which communicates with the outer region 15.
  • an intermediate piece 23 is used here, with which the guide channels 24, 25 are formed.
  • a guide channel 24 is connected to the explosive region 13, while a guide channel 25 has a radial end 26, which forms an inlet opening for air from the outer region 15 and an axial central end 27 which opens into the interior 22 of the flame arrester 21.
