Definitions
- the invention relates to a method for rendering one harmless detonation front conducted in a pipeline with the help of a Flame arrester.
- the invention further relates to a detonation protection with a suitable for installation in a pipeline or container system Housing in which at least one pipe socket with a certain Pipe diameter protrudes and in one the flame passage preventing flame arrester is arranged, the Diameter is significantly larger than the pipe diameter.
- the spread of an explosion of an ignitable gas mixture in a container or piping system can be used as a detonation or deflagration.
- the flame propagation rate of deflagrations are around 100 m / s and Combustion pressures in the direction of impact at up to 10 bar (at one Output pressure of the mixtures of 1 bar), during detonations Flame propagation speeds of several 1,000 m / s and pressures in the direction of impact of up to 100 bar can occur.
- a detonation device consisting of a detonation brake and a flame arrester is known from DE-PS 1 192 980.
- the detonation front propagating through a pipeline is in the known device by the convex outside divided and arrives a circular cylindrical wall into an expansion room with an enlarged one compared to the pipeline Volume.
- the split detonation front can only after several deflections against the flame arrester, which run in an outlet connector is attached, which is 90 ° compared to the Pipeline is angled in which the detonation originally occurred has spread.
- the multiple redirections will be generated in that a second semicircular cylindrical wall with a smaller diameter is provided, with each other free wall pieces are arranged overlapping each other and thereby form a kind of labyrinth.
- DE 195 36 292 C2 discloses the detonation front to divide into a main front and a side front and the Main front with a longer term in the expansion space direct so that when the main front enters the expansion space this contains the combustion gases of the secondary front.
- the breakdown the detonation front into a main front and a side front, the main front being a longer term to the expansion space needed also requires redirects for a Minimum volume of the realized according to this procedure Ensure detonation protection. Due to the need for an upstream Bumper at least for the main front in addition, a relatively high production cost. this applies especially when the detonation device is on both sides can be acted upon by detonation fronts and therefore be fitted with a bumper on both sides of the flame arrester got to.
- the flame arrester without a bumper.
- the Column of flame arrester should be chosen long and narrow, which high pressure losses due to the flame arrester are accepted have to.
- the flame arresters with lower pressure drops can namely the flame front entering the flame arrester Push lighter unburned mixture through the flame arrester. This creates direction in the flame-extinguishing gaps the flame progress a greater flow velocity and thus turbulence, which the combustion rate in the flame-extinguishing columns increased and thus the extinguishing capacity and thus the flame arresting security is reduced.
- Flame arresters with a high insulation, i.e. a high one Protection against ignition breakdown due to narrow and long gaps the considerable operational disadvantage arises of the high pressure loss.
- the present invention is therefore based on the problem to ensure protection against detonations that occur with simple and inexpensive to create funds does not cause a high pressure loss for the gases flowing through and still guarantees a high level of ignition resistance.
- the diameter of the flame arrester compared to the pipe diameter must be designed extremely large, it is appropriate to the detonation front in several partial detonation fronts on several To manage parts of the flame arrester. This also allows for the large diameter difference between pipeline and Flame arrester in normal operation is sufficiently uniform Inflow of the flow medium over the entire area of the flame arrester to reach.
- the invention thus makes it possible to protect against detonation without its own bumper and only with a flame arrester train without the flame arrester causing high pressure drops leads in normal operation.
- the essence of the present invention consists of the detonation front only in a partial area to let the flame arrester hit it by the detonation front with a pipe socket very close to the Flame arrester is introduced. This creates on the incoming Side of the flame arrester an expansion space so that the Detonation front in front of the flame arrester in the expansion room Secondary ignition can cause deflagration. Because the flame arrester only hit in part by the detonation front it offers a high flow resistance for the detonation front.
- the free cross-sectional area of the entire flame arrester is preferably equal to or larger than the pipe diameter of the pipe socket.
- the Pipe piece so close to the flame arrester that the sub-area hit by the detonation front essentially corresponds to the pipe diameter.
- the flame arrester has it preferably an entire diameter of at least twice of the diameter of the section corresponds to in normal Operation to achieve low pressure drops.
- the mode of operation of the arrangement according to the invention is related on the flame extinguishing behavior the more favorable the denser that End of the pipe socket is brought up to the flame arrester.
- the detonation protection according to the invention free distance between the end of the pipe socket and the flame arrester greater than / equal to a third and less than / equal to that Pipe diameter.
- the cross section of which is approximately the cross section of the Flame arrester corresponds to the length of the interior on the Side of the pipe socket to the flame arrestor preferably more than 0.6 times the tube diameter and can preferably less than / equal to twice the pipe diameter and can, in particular when using a preignition explained below can be reduced to half the pipe diameter.
- the inventive effect of hitting the detonation front to the section of the flame arrester through which the flame arrester the detonation front has a high flow resistance, can be reinforced by the flame arrester is designed differently in the partial area than in the Partial area surrounding edge area.
- the Flame arrester in the partial area with narrower gap widths than in the edge area, with the gap length expediently Flame arrester for production reasons over the entire Cross section is the same.
- the detonation protection according to the invention can be in the pipe socket with small connection openings to the pipe diameter to the the expansion space surrounding the pipe socket to be provided by pre-ignition through the detonation front in the expansion space to cause a pre-combustion so that by pre-burned Gases of a tendency to re-form a detonation front in the expansion space, especially by reflection the end wall of the expansion space, which is removed from the flame arrester, countered effectively, so that the length of the expansion space can be reduced.
- the detonation protection For dividing the detonation front into several partial detonation fronts can the detonation protection according to the invention
- FIG. 1 shows schematically a detonation fuse, the how this is shown in dashed lines, with a in a pipe 1 insertable housing 2 is formed.
- the housing 2 is on flanged to the pipe at both ends and forms one Interior 3 of the housing 2.
- In the interior 3 protrudes from one A pipe socket 4 continuing the pipeline 1, that in front of a flame arrester arranged centrally in the housing 2 5 ends.
- the flame arrester 5 between two halves 6 of the housing by flange connections 7 held.
- FIG. 1 shows a detonation front starting through the pipe socket 4 8, the one as a partial area 9 of the flame arrester 5 hits.
- FIG 2 illustrates that the pipe socket 4, which continues the pipeline 1, has a diameter D and that the detonation front 8 practically impinges with the diameter D on the portion 9 of the flame arrestor 5, which thus also has approximately the diameter D.
- the shock wave of the detonation front 8 strikes the small diameter D of a relatively high flow resistance of the flame arrestor 5, so that the detonation front 8 is partially reflected by the flame arrestor 5 or is extinguished when penetrating into the partial area of the flame arrestor 5.
- the detonation front causes secondary ignition in an expansion space 13 of the housing 6.
- the expansion space 13 extends over a length L 1 from the mouth of the pipe socket 4 back away from the flame arrestor 5.
- a deflagration occurs in the expansion space 13, which strikes the outer area of the flame arrestor 5 with a substantially lower flame propagation speed and lower combustion pressure. Due to reflections on the walls of the expansion space 13, in particular on an annular end wall 10 surrounding the pipe socket 4, the deflagration could form again in a detonation front. This is counteracted by a sufficient minimum length L 1 , since the deflagration front that is reflected and detonated then strikes a mixture that has already burned in front of the flame arrestor 5 and is therefore ineffective.
- the free cross section of the flame arrestor 5 corresponds at least the cross-sectional area of the pipe socket 4 with the pipe diameter D or is larger, so that for a not according to Figure 3 as Detonation front 8, but crossing as normal flow 11 Gas no significant pressure loss through the flame arrestor 5 arises.
- Figure 3 shows that the free distance L 2 between the mouth end of the pipe socket 4 and the pipe socket 4 facing surface of the flame arrestor 5 is selected so that the flame arrester 5 is flowed evenly from the flow medium in normal operation. This is the case if the length of the space L 2 is greater than / equal to a third and less than / equal to the inner diameter D.
- the embodiment shown in Figure 4 corresponds to that 1 with the only difference, that a pipe socket 4 is provided on both sides of the flame arrestor 5 is, so that the detonation protection shown in Figure 4 for detonation fronts 8 suitable is.
- the further embodiment of the invention shown in Figure 5 differs from the embodiment shown in FIG. 1 in that the flame arrester 5 'in the partial area 9 'is made with narrower gap widths, so that the flame arrester 5 'of the detonation front 8 through the narrowed section 9 'still opposes a higher flow resistance.
- the pipe socket 4 is provided with small connection openings 12 through which a part branches off from the incoming detonation front 8 immediately after the start of the housing 2 and directly into the Expansion space 13 is directed, where a pre-combustion takes place by the ignition of the branched off part of the detonation front 8, so that burned gases in the expansion space 13 prevent the formation of a secondary detonation by reflecting a deflagration on the rear wall 10 of the housing 2 and thereby reduce the length L 1 can be.
- the fifth exemplary embodiment shown in FIGS. 7 and 8 provides for the flame arrester 5 to be designed to be extremely large compared to the diameter D of the pipeline 1 in order to obtain a very low pressure loss through the flame arrester 5 in normal operation.
- FIG. 7 illustrates that a detonation front that starts in the pipeline 1 is distributed over several partial detonation fronts 8 ′ which strike the associated partial regions 9 ′′ of the flame arrester 5.
- the rear end wall 10 ' which delimits the length L 1 of the expansion space 13' is formed by wall pieces which, in the flow direction in front of the flame arrester 5, delimit a distributor chamber 14 which, starting from the diameter D of the pipeline 1, widens to the effective diameter of the flame arrester 5 and passes into the pipe socket 4 '.
- the arrangement of the pipe socket 4 'shown in FIG. 7 has a central pipe socket 4' which is flush with the pipe 1, but has a somewhat smaller diameter than the pipe 1.
- Four further pipe sockets 4 ' are arranged on a radius around the central pipe socket 4' equally spaced.
- FIG. 8 illustrates normal operation, in which normal partial flows 11 ′ pass through the pipe socket 4 ′ and are distributed evenly over the cross-sectional area of the flame arrester 5.
- FIGS. 9 and 10 are missing compared to the fifth embodiment a central pipe socket 4 '. Rather, there are only two pipe sockets 4 'shown, both at an equal distance to the central axis of the housing 2 or the flame arrestor 5. With this arrangement, partial detonation fronts 8 ' ( Figure 9) or normal partial flows 11 '( Figure 10).
- the optimization of the lengths L 1 and L 2 depends on the pressure loss through the flame arrester 5 from.
