Definitions

  • the invention relates to a sprinkler with a cage for producing extinguishing foam from a foaming agent-containing extinguishing fluid (for example water) for combating fires.
  • a foaming agent-containing extinguishing fluid for example water
  • Fire-extinguishing foam consists essentially of air, water and a surfactant-containing foaming agent.
  • the extinguishing foam can be distinguished into fluorosurfactant-containing foams ("AFFF” or "A3F” foam extinguishing agent) and fluorosurfactant-free extinguishing foam, whose different mode of action is briefly explained below.
  • AFFF foaming agent When using AFFF foaming agent, the fluorosurfactants, due to their chemical structure different from conventional hydrocarbon surfactants, cause a vapor-tight, aqueous liquid film of usually 10-30 ⁇ m thickness between the burning surface and the foam. This fluorosurfactant caused water film acts as a barrier against the escape of fumes and prevents an inflammation. Because of these properties AFFF foam agents are also referred to as “film-forming foams", which is reflected in its abbreviated form "AFFF" or "A3F” for "A qeous F ilm F orming F oam".
  • Another significant advantage associated with film formation is that the foam layer deposited on the film does not have to have an outstanding barrier function, ie the foam must have no or only a low foaming number.
  • AFFF Foaming agents with a foaming of less than 4, usually between 1.5 and 3.0 sufficient, since the main quenching effect caused by the fluorine surfactant gas-tight liquid film on the burning surface is effected.
  • These aforementioned low foaming numbers are achieved using conventional sprinklers designed for operation with water or AFFF foam extinguishers.
  • these conventional sprinklers can not afford a higher foaming number because of their design. But then it has to technically complex special sprinklers, for example, in the DE 195 39 991 C1 disclosed type of a heavy foam sprinkler, are used, which are about 40% to 70% more expensive and the construction much more complicated than the conventional sprinklers.
  • Such heavy foam sprinklers are installed in particular where AFFF extinguishing foams must not be used due to the harmful properties of the fluorosurfactant component (persistent, bioaccumulating, toxic) or conventional sprinklers previously operated with AFFF extinguishing foam have to be converted to heavy foam sprinklers due to the prohibition of fluorosurfactants. See, for example, the application restrictions of Directive 2006/122 / EC. Since fluorosurfactant-free extinguishing foam lacks the film barrier in the absence of fluorosurfactants, essentially only the foam layer acquires the required barrier function. However, this is effective only from a VerDumungsiere of 4, from which one usually speaks of foam and the use of special above-mentioned Schwerschaumsprinkler requires.
  • the cage according to the invention is an accessory for a conventional sprinkler and serves to produce extinguishing foam from a foaming agent-containing extinguishing fluid.
  • the conventional sprinkler comprises an extinguishing fluid outlet opening, one to the extinguishing fluid outlet opening in the axial direction opposite spray plate and sprays the extinguishing fluid through the spray plate with a VerDumungsress that without the inventive cage is well below that of low foam (starting with a VerDumungsiere of 4).
  • Exemplary shielded sprayers of this type are the Victaulic Shield Sprayer V2704 (K80) and the Tyco Shield Sprayer TY315 (K80).
  • a cylindrical gap formed between the base area (G) of the spray plate and the extinguishing fluid outlet opening can be defined, the diameter of which corresponds to the outer diameter (d 1 ) of the spray plate and its height (h 1 ) starting from the center of the base area (G ) corresponds to the distance to the extinguishing fluid outlet opening.
  • the cage provided for sprinklers of this type has screen openings with a diameter between 1.00 mm and 7.00 mm and / or grid openings with a width between 1.00 and 7.00 mm and a length between 2.00 mm and 9, 00 mm, preferably formed by an expanded mesh, on, which allow the passing through the cage extinguishing fluid flow in combination with its specific dimensions to refine heavy foam.
  • expanded metal is particularly suitable (not deburred) expanded metal, because the sharp edges of the material cause a particularly good foaming.
  • the cage according to the invention covers the aforementioned Sprinkler formatraum, wherein the height (h 2 ) of the cage corresponds to at least 0.20 times the outer diameter (d 1 ) of the spray plate.
  • the inner diameter (d 2 ) of the cage alternatively the non-circular minimum distance between the opposite inner sides of the cage, at the height of the spray plate in the installed state at least equal to Outer diameter (d 1 ) of the spray plate.
  • a light dimension (b) can be defined as a gap
  • this clear dimension lies between the inside of the cage (1) and the spray plate (4) at the level of the spray plate according to a preferred embodiment of the invention circumferentially between the 0.10 to 3.00 times, preferably between 0.50 to 2.00 times, more preferably between 0.75 to 1.50 times, more preferably between 1.00 and 1.25 times the outside diameter (d 1 ) of the spray plate.
  • the invention has recognized that the radial distance between cage and spray plate has a direct influence on the VerDumungsiere and thus advantageously can vary. Comparative tests have shown that the foaming number increases with increasing distance.
  • the cage has a height which allows most of the extinguishing fluid deflected by the spray plate to pass through the cage according to the invention.
  • This height (h 2 ) of the cage is advantageously at least 0.50 times, preferably 0.75 times, more preferably 1.00 times the outside diameter (d 1 ) of the spray plate and may be, for example, the height (h 1 ) correspond to the Sprinkler responsibleraums.
  • the height (h 2 ) of the cage can be defined such that it corresponds to the height (h 1 ) of the sprinkler space, preferably less than 0.75 times that of the height (h 1 ) of the sprinkler space, more preferably less than 0.50 times that of the height (h 1 ) of the sprinkler space.
  • the cage according to the invention may have any suitable shape, for example the shape of a hollow cylinder, a hollow cone, a hollow truncated cone, a Holpyramide, a hollow sphere or a combination of these forms, wherein the hollow cylinder shape is particularly preferred.
  • the cage may extend in the axial direction tapering beyond its area that surrounds the gap and, for example, open into an opening with an inner diameter that is larger than the outer diameter (d 1 ) of the spray plate. The latter is particularly advantageous to allow unhindered falling out of small parts of the commonly used trigger elements (bursting with liquid, fusible link, etc.) from the sprinkler, which otherwise caught in the cage sieve or grid openings can prevent their intended function as VerDumungsetti.
  • the cage is shaped as a wood cylinder, the (upper) end facing the extinguishing fluid outlet opening is open over the entire diameter surface, while the opposite end tapers axially at the level of the spray plate and opens into an opening below the Sprühtellers.
  • the cage grid openings have a width between 2.00 mm and 6.00 mm and a length between 3.00 mm and 8.00 mm, preferably a width between 2.50 mm and 4.50 mm and a Length between 5.00 mm and 7.00 mm.
  • the cage grid can further advantageously, an expanded metal mesh with a mesh width between 2.50 mm and 4.50 mm, a mesh length of 5.00 mm to 7.00 mm and a thickness of 0.40 mm to 0.80 mm, preferably a mesh width of 3.50 mm, a mesh length of 6.00 mm and a thickness of 0.60 mm.
  • the cage has screen openings with a diameter of 1.50 mm to 2.50 mm, preferably 1.75 mm to 2.25 mm, particularly preferably 2.00 mm.
  • the cage is preferably made of metal, for example made of steel, and particularly preferably made of stainless steel (eg stainless steel V2A).
  • the cage further comprises a holder for attaching the cage to the sprinkler.
  • This support may, for example, be designed as retaining arms which fix the cage with the base of the sprinkler in the region of the extinguishing fluid outlet opening on the sprinkler body or on its connecting thread arranged above it, for example via several (for example 2, 3, 4, 5 or 6) clamping feet.
  • the support arms or clamp feet can be provided with predetermined breaking points for easier shortening in order to be able to make a positioning of the cage in relation to the sprinkler in a simple manner depending on the sprinkler and the installation conditions.
  • a securing element for example a binding element (cable tie, metal strip, etc.) that radially surrounds the retaining arms or clamping feet.
  • the cage according to the invention is particularly suitable for conventional shielded sprinklers, which can be upgraded or retrofitted with the aid of the cage in order to achieve higher foaming values. This is especially true for Foaming agent-containing fluorosurfactant-free extinguishing fluids in which the advantage of the cage is particularly significant.
  • the cage according to the invention it is possible with the cage according to the invention to produce extinguishing foam having a foaming number of from 3 to 9, preferably from 4 to 8, more preferably from 4.5 to 7, particularly preferably from 5 to 6.
