Definitions
- the invention relates to a flame arrester arrangement with at least two in Flow direction of a combustible gas flame arrester elements arranged one behind the other, which have a variety of columns to wipe out one on the Have surface of a flame arresting element, and with at least one spacer between flame arresting elements by one Gap between adjacent flame arrester elements cause.
- Flame arresters are used to protect against explosions, detonations and permanent fire Fittings with a so-called flame arrester, which propagate the flames of explosions, detonations or Continuous fire and thus flame penetration prevented. It's a lot of different ones Constructions of flame arresters are known to be essentially in the category of static dry, static wet and dynamic Flame arresters can be classified.
- Such flame arresters can be used as close-meshed sieves, plate safety devices, Sintered metals, spherical fillings and designed as so-called tape fuses become. It is essential that the column of the flame arrester selected for securing can be kept reproducibly within very narrow tolerance ranges. Therefore, tape backups are primarily used today, which by Winding a smooth and a corrugated tape are produced.
- the corrugated band is straight, or left or right bevelled corrugations that define the gap width. This is in the range from 0.2 to max. 1.5 mm depending on the explosion mixture.
- flame-proof valve Explosion, detonation or Long-term fire protection devices
- two, three or more tape lock washers as flame arrester elements, optionally in combination with a surrounding cage to increase the mechanical strength to a complete Flame arrester summarized.
- a generic flame arrester is e.g. disclosed in EP 0 375 455 A2. It is a flame-arresting tap with a flame arrester out of four a flow direction of a combustible gas arranged one behind the other Flame arresting elements shown. Between the individual flame arrester elements narrow spaces are provided that form an expansion zone for the gas in the crevices and create a turbulent flow of the Lead gas. The spaces vverden by spacing elements between the flame arrester elements.
- the conventional spacers are traditionally used in assembly a multi-layered flame barrier loosely between the Flame arrestors placed.
- the spacer elements are, for example from a closed triangular or polygonal or loop-like wire ring educated.
- the object of the invention was therefore to provide an improved generic flame arrester to accomplish.
- the task is accomplished by the flame arrester with the characteristics of the main claim solved in that the one spacer at least at certain points is connected to the surface of an associated flame arresting element
- the spacing elements are preferably connected at points, e.g. in the Spot welding process, so that the available for gas and liquid passage Surface of the flame arresting element is not unnecessarily reduced.
- the spacer elements are preferably shaped so that they cover the entire Surface of the corresponding tape securing element distributes support points form, so that a deflection of the band locks prevents under pressure load becomes.
- the conventional spacer elements offer only unevenly distributed contact surfaces, some of which are only on the outside Offer peripheral points of the flame arrester elements.
- the spacing element can be e.g. be lattice-shaped.
- the spacer elements can be made of wire mesh, wire mesh and / or round rods be educated.
- the enclosure cage 3 is in two parts, so that the flame arresting elements 2a, 2b, 2c are easily assembled and can later be disassembled for replacement and cleaning.
- the two Parts of the surrounding cage 3 are held together by a screw connection 4.
- FIG. 2 shows a cross-sectional view of a flame arrester component with a Recognize flame arrester element 2, on the surface of which a spacer element is arranged.
- the spacer 5 is fixed to the surface of the flame arrester element 2 preferably by means of spot welding connections 6 connected. In this way, the flame arrester component is stabilized and mechanical damage during removal or cleaning as well as a Deformation of the flame arrester component when a detonation wave strikes prevented.
- FIG. 3 shows the flame arrester component from FIG. 2 in a top view.
- the spacer 2 consists of a plurality of parallel ones Bars exist that are spaced apart and evenly over the entire surface of the flame arresting element 2 distributes support points for form an adjacent flame arrester component. This will cause deflection of the flame arresting element 2 when subjected to pressure, in particular when striking a detonation wave effectively prevented.
- FIG. 4 shows an advantageous embodiment of a spacer element 2 recognize that is formed from a wire mesh. At the crossing points the wire mesh becomes the spacer 5 with the associated flame arresting element 2 spot welded, as in the cross sectional views of the Figures 5 and 6 can be seen.
- FIG. 7 shows a top view of a flame arresting element 2 with the wire grid-shaped one Spacer 5 recognize that even on every second Cross point a spot weld 6 with the flame arrester 2 has.
- FIG. 8 shows a flame arresting element 2 in the embodiment of a band securing element recognize in the cutout as a top view.
- the tape securing element is made of a smooth band 7 and a corrugated one above it Band 8 formed, which are wound spirally.
- the smooth band 7 and the corrugated band 8 are usually about 10 mm wide.
- the corrugation in the corrugated band 8 defines the gaps.
- the gap width SW depending on the medium for which the tape securing element is designed, is in the range from less than 0.2 mm to a maximum of 1.5 mm.
- FIG. 9 leaves a conventional flame arrester 1 with three in the flow direction of a combustible gas flame arrester elements 2a, 2b and 2c recognize that are installed in a surrounding cage 3.
- the spacer elements 5 are loosely between the flame arresting elements 2a, 2b and 2c are inserted and lie only unevenly on the surface of the corresponding flame arrester element 2a, 2b or 2c.
- Figure 10 shows an embodiment of a conventional triangular Spacer 9, which is loosely inserted between the flame arresting elements 2 becomes. It can be seen from the cross-sectional representation that the spacer element 9 is formed from a round wire.
- Figure 11 leaves another embodiment of a conventional loop-shaped Detect spacer 10, which is also loosely between the Flame barrier elements 2 is inserted and unevenly on the surface of the corresponding flame arrester element 2 rests.
- the cross-sectional representation shows that the spacer 10 is also made of a round wire is formed and the bearing surface in cross-section unevenly on the Surface of the corresponding flame arresting element 2 is distributed.
