Abstract
The invention relates to a system for ensuring evacuation and rescue from the effects of smoke, heat and pollutants in areas with long evacuation routes, such as mining installations, underground transport systems, or similar. Said system takes advantage of the characteristics of a mist of water, which is generated by misting means, in such a way that the air lying in the area below the layer of fumes can be respired for a long period of time and its clarity can at least be maintained, so that the direction of evacuation remains visible. According to the invention, the sprinkler nozzles (3), which generate the mist, are fixed to sprinkler arches (2) that are positioned along the entire length of the area and/or its evacuation routes, one behind the other, transversally to the direction of evacuation, following the clearance contours of the area and/or the evacuation routes. The arch-type arrangement of the sprinkler nozzles (3) over the entire length of the areas and evacuation routes divides the structural installations into sections, which do not impede the basic air flow (6) present in the installation, in such a way that the smoke or pollutant flow is not accumulated by the mist that is produced.
Description
Arrangement for ensuring evacuation and rescue from the effects of smoke, heat and pollutants.
The invention relates to an arrangement for ensuring evacuation and rescue from the effects of smoke, heat and pollutants from spaces with long escape routes such as mining installations, underground transport systems and the like.
Sprinkler-equipped systems for firefighting and rescue from underground spaces, and more particularly from highway and railway tunnels, are often installed in test installations. However, the inadequacy of such systems has been demonstrated both In accidents and in practical trials. The reasons for this can be found in the relatively large water drops and the speed at which they are discharged from the sprinklers, which renders them incapable of binding smoke and pollutant particles. In fact, their high speed of discharge and their size perturb the flow, which may either be natural or induced by exhaust systems, of the layer of smoke moving in the open air. This causes the layer of fumes to mix with the more fume-free layer below it, reducing vision and breathing for both the evacuees and the rescue personnel and thus making both the evacuation and the task of the rescue personnel more difficult. in addition, the high water intensities required with sprinkler systems lead to partial extinction of the fire.
However, there is an extreme danger of flashback from those areas of the fire already extinguished. Inflammable gases and vapors are propagated unnoticed and re-ignite at the first opportunity. The deflagrations or even explosions thereby created have already shown devastating results in underground installations such as transportation tunnels. This danger is particularly high in cases where inflammable fluids are joining the fire, as is frequently the case with vehicle fires in tunnels.
Significantly better suited for containment of the consequences of fires are systems which operate on the basis of the procedure described in German Patent DE-PS 195 14 923 C2 for ensuring evacuation and rescue from the

The deflagrations or even explosions thereby created have already shown devastating results in underground installations such as transportation tunnels. This danger is particularly high in cases where inflammable fluids are joining the fire, as is frequently the case with vehicle fires in tunnels.
Significantly better suited for containment of the consequences of fires are systems which operate on the basis of the procedure described in German Patent DE-PS 195 14 923 C2 for ensuring evacuation and rescue from the
2 effects of smoke and heat. The principle underlying this invention consists in reducing the smoke and pollutant concentration by extremely fine water droplets or water mist, hereinafter called simply "mist," in order to improve breathing and vision in the area of hazard so that evacuation and rescue from the tunnel is considerably facilitated. Furthermore, the descending, fire-inhibiting mist acts to avert a sporadic, spatially limited extinction of the fire. This is achieved by means of a mist having lower discharge and/or propagation speed, and whose particle density possesses the concentration required to bind the smoke, heat and pollutants. The particle size of the mist is set in such a way that the water particles sink slowly from their point of departure without affecting the visibility in the space. The water mist nozzles are arranged in the upper area of the tunnel along its ceiling in the same way as sprinkler systems, so that their direction of spray can be varied in a direction parallel and perpendicular to the ceiling.
A
sectional arrangement of water mist nozzles enables them to be operated in a pulsed sequence. Installed sensors detect the fire and trigger the mist nozzles installed in the immediate vicinity of the fire.
Practical trials have in fact demonstrated significant advantages over traditional sprinkler systems, but this mode of operation still did not satisfactorily achieve the desired effect. And it has the disadvantage that the natural flow of the smoke layer was still too strongly affected by the emerging mist and that it consequently became mixed with the low-smoke layer, although the cleansing effect of the fine mist droplets on the smoke was demonstrably present.
Another form known to art for combating smoke in enclosed spaces is the application of water curtains. To achieve this, extinguishing agent spray devices are arranged so that in case of fire the agent being discharged forms a curtain which is impenetrable to fumes. But in this case a sufficient effect is achieved only in combination with high-performance fume extraction devices, which must then be fitted for the entire space that is partitioned off between the water curtains. Aside from the high expense this requires, systems of this kind are

But in this case a sufficient effect is achieved only in combination with high-performance fume extraction devices, which must then be fitted for the entire space that is partitioned off between the water curtains. Aside from the high expense this requires, systems of this kind are
3 unsuitable for the evacuation and rescue of persons, since orientation is absolutely impossible within such a space. As already mentioned, water curtain divisions are always simultaneously linked with high-performance fume extraction systems. The spray system must thus always be arranged in such a way that at least one fume extraction system is located between them. In this way the space between two water curtains can quite possibly extend up to 100 m.
The problem solved by the invention is an arrangement for ensuring evacuation and rescue under the effects of smoke, heat and pollutants by using a mist generating means which exploits the characteristics of the mist in such a way that the air, at least in the region underneath the smoke layer, is breathable over a longer time and at least can be kept translucent so that the direction of evacuation remains identifiable.
According to the invention, the problem is solved by the characteristics of the first claim. The following claims 2 and 3 refer to practical embodiments of the arrangement.
The entire structural installation is divided into sections by the arched arrangement, according to the invention, of the spray mist nozzles over the entire length of the spaces and evacuation routes. These sections are not, as in the case with water curtains, areas partitioned off from each other, but rather allow the smoke or pollutant flow to be freely drawn off in the direction determined by the air flow present in each case and not affected by the water mist. This means that neither the arrangement of the spray arches transversely to the direction of the air flow nor the mist issuing from the nozzles impedes the air flow, which travels along with the smoke and pollutant flow, unaffected, in its natural or forced direction. The lower discharge force of the mist produces less turbulence in the smoke. Indeed, the mist nozzles, aimed in the direction of flow of the smoke and pollutant stream, support that flow. At the same time, the floating water droplets bind the dust, soot and pollutant particles contained in the smoke

These sections are not, as in the case with water curtains, areas partitioned off from each other, but rather allow the smoke or pollutant flow to be freely drawn off in the direction determined by the air flow present in each case and not affected by the water mist.

The lower discharge force of the mist produces less turbulence in the smoke. Indeed, the mist nozzles, aimed in the direction of flow of the smoke and pollutant stream, support that flow. At the same time, the floating water droplets bind the dust, soot and pollutant particles contained in the smoke
4 and sink to the floor with them. This is equivalent to a process of washing the smoke, which in this way becomes cleaner, that is, more transparent, more breathable and also cooler from section to section. The slow settling of smoke cleaned in this manner as the distance from the source of the fire increases is at that point less dangerous to persons. The generally damp atmosphere in the tunnel has a fire-inhibiting and ignition-inhibiting effect.
The arrangement of mist nozzles on each spray arch stems from their spray characteristics. The spray cones must slightly overlap each other, so that all spray cones cover the cross-section of the tunnel in the vicinity of the arch The interval between spray arches inside the tunnel depends on structural, safety and, not least, on economic considerations. The closer the interval, the more thoroughly will the gas stream be cleaned, and the more safe and successful the evacuation and rescue will be. At larger intervals, of course, the reasonableness of the length of the evacuation route must be taken into account.
When the system is operated in cases of accident, it is advantageous to activate one spray arch upstream of the fire source, so as to impede fire and smoke propagation against the air flow. The number of the spray arches arranged to aim in the direction of the air flow downstream of the fire source depends on the intensity of development of smoke and noxious gases.
A swiveling arrangement and control of the angle of discharge of the mist nozzles permits selective adaptation of the mist discharge to the flow conditions in the evacuation route to be protected. By adapting the direction of spray of the mist nozzles to the flow conditions, however, it is also possible to fit two parallel spray arches with mist nozzles spraying in opposite directions, and to incorporate a controllable water feed.
By means of the arrangement according to the invention, and by making use of relatively simple design means known to art, the characteristics of the mist can be exploited in such a way that the evacuation and rescue from spaces with long evacuation routes becomes significantly safer.
In what follows the invention will be more fully explained by means of a typical embodiment. In the annexed figures, Fig. 1 shows schematically an arrangement according to the invention installed in a tunnel following outbreak of fire, but before it is fully activated, and Fig. 2 shows the arrangement according to the invention in operation after the outbreak of fire.
The arrangement described in the present embodiment also provides very efficient and cost-effective fire detection, which though not the object of this invention, still serves the means for the extraction and direction of the smoke gases according to the invention. in this connection, reference is made to Patent Application DE 198 588 77.1. The details and operation of the fire detection will not therefore be more fully detailed in the following description.
As can be recognized from Fig.1, three spray arches 2 are shown arranged in the section of a transportation tunnel 1, each of them carrying a quantity of spray nozzles 3. The spray nozzles 3 are arranged to swivel in such a way that they can apply mist in a range between 0° and 90° to the direction of travel of the tunnel 1. As already mentioned, in normal operating status the spray nozzles 3 serve for the continuous extraction of tunnel gases for forwarding to a detection device, not more fully represented. The spray arches 2 are installed, perpendicularly to the direction of traffic, on the clearance contour of the transportation tunnel 1 and conformably to the shape of its walls. The installation of the arrangement therefore causes no restrictions on the height nor on the width of the space available for vehicle traffic. The spray arches 2 are connected to a water supply 4. This can be achieved without particular additional expense if a fire fighting water line has been installed in the tunnel.
On the floor of the transportation tunnel 1 can also be seen a fire source 5, which is causing heavy smoke development. This is propagated mainly in the direction of the air flow 6 which prevails in the transportation tunnel 1, and in fact below the tunnel ceiling. A small portion of the smoke stream also moves against the air flow 6. Smoke development and propagation is designated by a cross-hatching of short horizontal lines.
The operation of the invention will now be explained using the arrangement represented in Fig. 2 in operation after detection of a fire. For clarity, the drawing shows only the central spray arch 2 and there only three of the spray nozzles 3 in operation. The range and direction of the mist being discharged is made clear by the spray cone 7, represented as a spatial grid work. However, all three spray nozzles 3 of all three spray arches 2 are in operation. It can also be seen that an active spray arch 2, seen in the direction of the air flow 6, is upstream of the fire source 5 and that both the other spray arches 2 are in place downstream of the fire source 5. The activity of the spray nozzles 3 is shown for al! spray arches 2 by means of the gray, gate-shaped areas 8 shown behind them. In fact, the effect of the spray nozzles 2 in action can be compared to or explained as a mist gate.
Further, it can clearly be seen that the direction of spray of the spray cone 8 is aimed in the direction of the smoke flow, that is, also in the direction of the air flow 6. Part of the spray nozzle 3 is aimed slantingly downwards. The effect of the three spray arches 2 as a mist gate for the smoke flow varies; the spray arches 2 located upstream of the fire source 5 impede the passage of the smoke against the air flow 6. That means that this area is kept smoke-free for fire fighting and rescue crews. At the same time, the smoke stream, even before it passes through the second spray arch 2, has already, under the effect of the mist, released in a first instance some of the smoke and pollutants, which sink to the floor with the mist droplets. Under the effect of the mist of the second spray arch 2, the smoke stream is freed a second time of the particles that impede vision and respiration, and is further cooled down. The gradual cleaning through the effect of the mist of the spray arches 2 is shown by a progressively less dense cross-hatching of the smoke stream in the area downstream of the associated spray arch 2. In this example, the last cleaning takes place after passing the third spray arch 2 under the effect of the spray discharged from it.
This is represented in the figure by a further thinning of the cross-hatching.
Depending on the intensity of smoke development and on the effect of the mist, the number of spray arches 2 to be activated can be selected appropriately.
The arrangement of mist nozzles on each spray arch stems from their spray characteristics. The spray cones must slightly overlap each other, so that all spray cones cover the cross-section of the tunnel in the vicinity of the arch The interval between spray arches inside the tunnel depends on structural, safety and, not least, on economic considerations.
