Definitions

  • the present invention relates to a method and a device for protection against fumes generated by fire and / or toxic substances, especially in tunnels.
  • the present invention advantageously makes it possible to use the effects of thermal convection and balancing drains to block smoke in the upper part of the tunnel to avoid as long as possible for the fumes to descend and suffocate people.
  • the main feature of the present invention is that by generating a mist of water in the lower part of a closed volume or tunnel, it acts directly on transfers balancing flows, it is therefore a process, since it uses a method, which to our knowledge has not yet been used.
  • the invention is characterized also by the implementation of a device capable of generating a water mist so as to limit its height to about 2 meters in the volume of the tunnel over its entire length or in part of it for the specific purpose of preventing the fall of smoke and / or toxic aerosol. (figure 1)
  • This process therefore has the extreme advantage on the one hand, of securing people by preventing fumes to come down thanks to a “saving” water mist, on the other hand, protecting them heat and thermal radiation, and in addition not to disturb the extraction of fumes.
  • the Mont Blanc tunnel disaster highlighted the deadly effects caused by smoke and toxic products from a fire.
  • the present invention provides a method advantageous, simple and effective.
  • the method of the invention consists in creating using a cloud of water droplets generated in the lower part and which are heavier than the ambient air, flow and form an occupying cloud the lower part of the tunnel, forming a "vault” preventing air movements between the floor and ceiling of the tunnel.
  • This "arch” by creating a significant pressure drop and forming an obstacle to the fumes, limits the movement of air and fumes in the upper part of the tunnel above the water mist. We therefore understand the great interest of this process which promotes the evacuation of people and facilitates access to emergency services.
  • the process of the invention can give rise to different applications, in particular to prevent the spread fumes, reduce or even prevent the spread of chemical pollutants, especially to the lower part of a tunnel.
  • the process will therefore have the advantage of preventing the fumes from going down, but also of fighting against all the effects of the fire, and in particular to prevent its expansion, because as and measure that the cloud of droplets will encompass the lower part of the fire, this one will weaken, it is obvious that even in the event that the droplets fail to extinguish it, it will be circumscribed quickly thus allowing the rescue services to approach it more easily.
  • the process will allow people in the tunnel, either to flee outwards, or to reach a refuge, of course, it would be desirable that the refuge be also protected, as proposed by another recent patent, the combining the two would multiply the benefits.
  • the method provides for the implementation of a device to achieve the goal. offers.
  • the device according to the invention will therefore generate a cloud of droplets limited to a height allowing on the one hand to partially block the smoke high on the other hand allow people to move safely in a cloud of droplets.
  • This device will operate either over the entire length of the tunnel, or by "Cantons” in this case it will operate sequentially and the sequence may be mobile as required.
  • the sequence corresponds to one or more cantons or sections set up services together or successively, the sequence must always be “calibrated” so that in all cases the cloud of droplets occupies the lower half of the tunnel to the right of the area in fire.
  • the system provides for the possibility of implementing a PLC programmed to activate the sections as needed, by successive opening of solenoid valves or manual valves.
  • the device of the invention operates as follows: detection of the fire by an appropriate means, for example detection from the operator by camera, or by infrared which can be preceded or confirmed by smoke detection and / or thermal.
  • the various detection means installed from one end to the other of the tunnel give the information to the programmable controller which controls the opening of areas to be misted, the PLC is programmed so that it systematically opens a section of fog upstream of people and / or vehicles in motion and closes the downstream section as it progresses which has the advantage of protecting people and property and to facilitate and make the emergency response more secure.
  • the system also provides for the use of nozzles installed in the upper part of the tunnel, but the nozzles would only be used by the emergency services, when they deemed it useful.
  • automaton is programmed to implement the setting means or means pressure and water supply to the device.
  • the device provides that the tunnel user has the possibility of triggering the water fog in the lower part of the tunnel by pressing one of the "punches" which will be placed along from the tunnel at an appropriate distance.
  • a device comprising: - one or more main pipes which cross the tunnel from one end to the other (1), De-pipes secondary (2) connected in diversions (3) of or Main pipes, solenoid valves (6) manual valves (16) of the water mist nozzles (4) installed on branch tees (5) and located approximately 2 meters high at the bottom of the tunnel on secondary and distributed pipes to allow water fog not to cover than the lower part of the tunnel to prevent smoke from going down.
  • the device can operate manually, but it is possible and even advisable to operate it at distance automatically, or through an operator, in this case the device also includes: a solenoid valve (6) controlled by a punch (17) and / or by a PLC (8) and / or by an operator (18) remotely by electrical or optical wired network or radio (7), infrared, thermocouple (9), thermovelocimetric (10) and / or smoke (11)
  • a non- pressurized, (14) a low or high pressure thermal and / or electric pumping group (12) controlled by an automaton, a pressurized tank (13) controlled by an automaton. Another possibility would be to place a tank at a height sufficient to supply the main network.
  • valves and valves allowing the connection of the device to the fire network when it exists, as well as the operation manual of the device, likewise provision is made for appropriate frost protection, either by antifreeze, insulation or heater if necessary. It is of course possible to connect to the device, a additive injection system, either against fire or against pollution by product chemical, a neutralizer for example, if necessary.
