DETAILED DESCRIPTION OF THE INVENTION
[0132]
[0133] On each of the storage arrangements 10a, 10b, 10c and 10d are disposed units 30 in block form. In the specific embodiment of
[0134] Also disposed on the storage arrangements 10a, 10b, 10c and 10d are a number of extinguishing fluid outlets 40 that belong to the second plurality of extinguishing fluid outlets. Extinguishing fluid outlets 40, in the specific embodiment of
[0135] The elevations 20a, 20b, 20c and 20d are configured such that storage arrangements 10a, 10b, 10c and 10d are configured thereon. For this purpose, elevations 20a, 20b, 20c and 20d each have a straight surface 22a and 22b (the straight surfaces of elevations 20c and 20d are not numbered for the sake of clarity). Even though elevations 20a, 20b, 20c and 20d in the specific embodiment of
[0136] The elevations 20a, 20b, 20c and 20d are also configured to direct the liquid hazardous material that has escaped from one of the storage vessels 60 in the direction of the collecting area 200. For this purpose, the elevations 20a, 20b, 20c and 20d each have an oblique surface 21a and 21b (the oblique surfaces of the elevations 20c and 20d are likewise not numbered for the sake of clarity). In some embodiments, the oblique surfaces may especially have a slope of about 1.0%, preferably 1.5%. The oblique surfaces 21a and 21b are configured to direct the liquid hazardous material, if it has escaped from one of the storage vessels 60 disposed in the lowermost level of the storage arrangement 10a, 10b, 10c and 10d, in the direction of the collecting area 200.
[0137] The collecting area 200 is hereby formed by the base 300 in the interspace between any two storage arrangements 10a, 10b, 10c and 10d. For instance, the area of the base 300 between the storage arrangements 10a and 10b forms a first collecting area 200, and the area of the base 300 between the storage arrangements 10c and 10d forms a second collecting area 200.
[0138] The first and second collecting areas 200 each comprise a plurality of fluid receptacles 201 (only one in each case can be seen in
[0139] The storage arrangement 10a and 10b, and 10c and 10d, further comprises a plurality of fluid-directing elements 70 that are disposed beneath the storage vessels 60 in the higher levels of the storage arrangement 10a and 10b, and 10c and 10d. The fluid-directing elements 70 have at least one base surface and an oblique fluid-directing surface connected thereto, as described once again in detail in association with
[0140] The functioning of the fluid-directing elements 70 basically corresponds to the functioning of the fluid-tight elevation 20a, 20b, 20c and 20d, except that the fluid-directing elements 70 exert this function for the storage vessels 60 that are not at the lowermost level of the storage arrangement 10a, 10b, 10c and 10d. For instance, the fluid-directing elements 70, in the event of leaking of the liquid hazardous material from a storage vessel, have the effect that the liquid hazardous material cannot escape either to the reverse side of the storage arrangement 10a and 10b, and 10c and 10d, or to the sides of the storage arrangement 10a and 10b, and 10c and 10d, but is instead directed downward via the oblique fluid-directing surface in the direction of the collecting area 200.
[0141] The fire protection system 1 of
[0142]
[0143] As shown in
[0144] As likewise shown in
[0145] In addition, the collecting area 200 comprises at least two fluid barrier elements 202 disposed at the first and second ends of the collecting area 200, in order to prevent the liquid hazardous material from spreading in longitudinal direction of the storage arrangement 10a. In the specific embodiment of
[0146]
[0147]
[0148] The alignment of the extinguishing fluid outlets 31 is now elucidated in detail in relation to
[0149] A specific configuration of an extinguishing fluid outlet 31 with a directional characteristic for the extinguishing fluid is described once again hereinafter in relation to
[0150] When the extinguishing fluid exits from the discharge opening 301, the spray plate 302, by virtue of its specific arrangement, has the effect that the extinguishing fluid exiting from the discharge opening 301 in the direction of the spray plate 302 is deflected by the spray plate 302, as shown by arrow C, and is thus aligned in the appropriate direction together with the extinguishing fluid that has already exited in that direction. Thus, a directional characteristic of the extinguishing fluid is achieved which, depending on the arrangement of the spray plate 302 and the sprinkler 31 in relation to the fire protection area, enables discharge of the extinguishing fluid directed to a specific position.
[0151] The arrangement of at least two extinguishing fluid outlets 31 from the first plurality of extinguishing fluid outlets of the unit 30 in block form is elucidated hereinafter in relation to
[0152] More particularly,
[0153] The functioning of the fluid-tight elements 70 is now elucidated once again in relation to
[0154] The fluid-directing element 70 according to
[0155] The fluid-directing element 70′ of
[0156] The fluid-directing element 70″ of
[0157] The fluid-directing elements 70 and 70′ also have one connecting element each (not shown in
[0158] The connecting elements may particularly be executed as overlapping segments of the base surface 74 and of the fluid-directing surface 75 and are especially configured to connect the fluid-directing elements 70, 70′ and 70″ to one another in a fluid-tight manner. This connection can be secured here by any securing element, for example rivets, screws or the like.
[0159] There follows an elucidation of the manner of function of the fluid-directing elements in relation to
[0160] Depending on the mode of storage—either three-position storage in which three storage vessels 60—or pallets with storage vessels disposed thereon—are disposed between two positioning elements of the storage arrangement 10a, 10b, 10c, 10d, or two-position storage, in which two storage vessels 60—or pallets with storage vessels disposed thereon—are disposed between two positioning elements of the storage arrangement 10a, 10b, 10c, 10d—either three fluid-directing elements 70, 70″ and 70′ or two fluid-directing elements 70, 70′ are connected to one another by connecting and securing the connecting elements of the individual fluid-directing elements to one another in a fluid-tight manner. The fluid-directing elements 70, 70′, 70″ connected to one another in this way are then inserted into the storage arrangement 10a, 10b, 10c, 10d. Then, depending on the mode of storage, two or three storage vessels 60 are positioned on the base surfaces 74 of the connected fluid-directing elements 70, 70′, 70″. If liquid hazardous material then leaks from one of the storage vessels 60, this is provided to the base surfaces 74 and spreads out thereon. The liquid hazardous material is prevented here from spreading by the reverse-side surfaces 72 and the first lateral surface 71 and the second lateral surface 71′, in that these function as fluid barriers. As a result, it is possible for the liquid hazardous material to spread only in the direction of the fluid-directing surfaces 75, by means of which it is directed into the collecting area 200, where it is preferably directed into the fluid receptacles 201. This way, the liquid hazardous material may be collected in the fluid receptacles 201 and be extinguished there if necessary. Since the liquid hazardous material in the fluid receptacles 201 has only a low surface area, the spread of a fire is greatly restricted and firefighting can be conducted in a localized manner. This eases firefighting.
[0161] In addition, the manner of function of the fire protection system according to
[0162] It may be the case that liquid hazardous material escapes from one of the storage vessels 60. If the storage vessel 60 in question is at the lowermost level of the storage arrangement 10a, 10b, 10c, 10d, the liquid hazardous material will arrive on the fluid-tight elevation 20a, 20b, 20c, 20d and spread over the straight area 22a, 22b of the fluid-tight elevation 20a, 20b, 20c, 20d. The fluid-tight elevation 20a, 20b, 20c, 20d comprises corresponding fluid barrier elements 23a, 24a for this purpose, which act as a barrier for the spreading liquid hazardous material, such that the liquid hazardous material cannot penetrate the sides of the fluid-tight elevation 20a, 20b, 20c, 20d or the reverse side of the fluid-tight elevation 20a, 20b, 20c, 20d, but is instead guided solely via the oblique surface 21a, 21b in the direction of the collecting area 200, in order to be collected there.
[0163] If the storage vessel 60 in question is at a higher level of the storage arrangement 10a, 10b, 10c, 10d, the liquid hazardous material, after leaking, will arrive on the fluid-directing elements 70, 70′, 70″, which are arranged within the storage arrangement 10a, 10b, 10c, 10d as in connection with
[0164] The liquid hazardous material is typically a combustible liquid having a combustion point down to −7° C., for example. This means that the liquid hazardous material is flammable at room temperature. If it escapes from the storage vessel 60, there is the risk that the liquid hazardous material will ignite, for example as a result of sparking. This fire event results in a temperature rise which can ensure that the first plurality of extinguishing fluid outlets 31 and the second plurality of extinguishing fluid outlets 40, 50, preferably executed as sprinklers in the embodiment according to
[0165] If, for example, liquid hazardous material escapes from a storage vessel at the second-lowest level of the storage arrangement 10a, 10b, 10c, 10d, the liquid hazardous material, as described above, is distributed over the base surface 74 of the fluid-directing element 70, 70′, 70″. In the event of sparking, the liquid hazardous material can ignite there. This leads to a temperature rise in the area of those extinguishing fluid outlets 40 disposed within the storage arrangement 10a, 10b, 10c, 10d in the immediate proximity of the storage vessel 60 in question. These extinguishing fluid outlets 40 are then triggered and release an extinguishing fluid with a 360° spray profile. Since these extinguishing fluid outlets 40 are disposed in the area of the rise in temperature, the extinguishing fluid exiting from the extinguishing fluid outlets 40 will affect the area in which the fire event is occurring.
[0166] In addition, liquid hazardous material is directed in the direction of the collecting area 200 by the arrangement of the fluid-directing elements 70, 70′, 70″.
[0167] Disposed in the collecting area 200 are a plurality of fluid receptacles 201. The number and size of the fluid receptacles 201 is chosen here such that the fluid receptacles 201 can accommodate the entire contents of a storage vessel 60. The fluid receptacles 201 are executed as narrow channels sunk deep into the floor 300. This execution in the form of deep channels allows the liquid hazardous material to collect in the fluid receptacles 201, in which case it has only a low surface area that can be on fire. This enables localized firefighting.
[0168] In the collecting area 200 too, the liquid hazardous material results in a temperature rise. The effect of this is that the extinguishing fluid outlets 31 disposed on the unit 30 in block form on at least one adjusting element 11a, 12a, 13a of the storage arrangement 10a, 10b, 10c, 10d are triggered. The extinguishing fluid outlets 31, which are implemented as sprinklers in the specific embodiment of
[0169] This interaction of extinguishing fluid directed onto a target area and collecting, by means of the fluid receptacles 201, of the liquid hazardous material in the area into which the fluid has been directed results in rapid and controlled extinguishment of the liquid hazardous material. In particular, it is possible by means of this arrangement of extinguishing fluid outlets 31 and fluid receptacles 201 to provide a method that enables control and possibly extinguishing of liquid hazardous materials even by means of an extinguishing fluid which is otherwise typically not usable for hazardous materials of this kind. In order to provide this specific combination, the extinguishing fluid outlets are especially arranged such that they discharge in different directions, as also shown schematically in
[0170] As mentioned above, it is possible not just to control the liquid hazardous material in the collecting area by means of the extinguishing fluid outlets 31, 40, 50, but also the liquid hazardous material within the storage arrangement 10a, 10b, 10c, 10d. This may especially be accomplished by means of the extinguishing fluid outlets 40 disposed on the storage arrangement 10a, 10b, 10c, 10d, and also by the extinguishing fluid outlets 50 disposed on the roof 400. For this purpose, the fire protection area may be covered virtually completely up to the roof 400.
[0171] The relative mutual arrangement of storage arrangement 10a, 10b, 10c, 10d, extinguishing fluid outlets 31, 40, 50 and collecting area 200, especially with the fluid receptacles 201, thus permits control either of liquid hazardous material locally and with standard extinguishing fluids and fighting of any fire events.
[0172]
[0173] The difference from the embodiment of
[0174] In the specific embodiment of
[0175] The advantage of this implementation is that a smaller number of extinguishing fluid outlets may be provided in the storage arrangement without reducing fire protection efficiency. This is because the first plurality of extinguishing fluid outlets, by virtue of its first defined directional characteristic, effectively discharges the extinguishing fluid onto a target area, for example one or two of the storage vessels, whereas the extinguishing fluid outlets of the second plurality (as described in connection with
[0176] Although two embodiments have been described above, in which the extinguishing fluid outlets disposed on the storage arrangement are either extinguishing fluid outlets of the first plurality or extinguishing fluid outlets of the second plurality, it will be appreciated at this point that it is also possible to dispose a combination of extinguishing fluid outlets from the first and second plurality on the storage arrangement and/or the roof arrangement in order to fight the fire event. The selection of extinguishing fluid outlets here should particularly be chosen such that it is possible to perform both extinguishing of liquid hazardous material in the collecting area and in the storage arrangement.
