Definitions

  • the invention relates to a mechanical smoke and heat exhaust system for smoke extraction from structures, e.g. buildings, Tunnels and a. to escape for people with smoke and warmth and / or harmful gases or aerosols exposed areas and the emergency personnel have access to them or the fire brigade to enable targeted extinguishing attacks. Furthermore, damage to the constructional facilities including things contained therein become.
  • Smoke and heat exhaust systems are essentially in the EN-DIN 18232-1: 1998-01. With mechanical smoke extraction it becomes a derivative of smoke and heat from construction systems a pressure difference between a smoke section and the external environment of the building Plant generated. In addition, it is known to be built To protect against the ingress of smoke or generated by means of overpressure Discharge smoke safely.
  • Conventional mechanical smoke and heat exhaust systems essentially consist of a suction pressure generator, for example a smoke extraction fan, an energy supply for this and a smoke control system.
  • the smoke extract fans are installed at prescribed locations, usually in the roof or wall area of the building. According to the above DIN, such systems are to be set up so that they reliably discharge smoke and heat from the building over a period of approximately 20 minutes until the fire brigade arrives. If the fire brigade's approach routes are long, it only makes sense to set them up in conjunction with automatic extinguishing systems. The reason for this is that the performance of fans is limited. That is why smoke and heat extraction systems are only effective in the event of a fire. This performance restriction also has the consequence that the smoke section surfaces acc. the above-mentioned DIN are limited to 1600 m 2 .
  • the fire brigade in the event of a fire and also after the Fire fighting ventilation equipment used to smoke and Remove harmful gases from rooms. This is done both by blowing of fresh air as well as by extracting the smoke and harmful gases.
  • mobile smoke extraction systems are for example in the prospectus of Hale Products Europe GmbH.
  • the object is achieved by the features of the patent claim.
  • the sub-claims 2 to 6 show different installation and application options of the suction pressure generator and the gas or steam supplier.
  • the known variant of the fixed installation of the smoke and heat exhaust system on the building system is still a frequently practicable solution. If available, the suction side of the gas or steam jet vacuum pump is connected to the duct system provided for smoke extraction from the building system.
  • the performance of the smoke and heat extraction signal according to the invention also allows the suction side of the gas or steam jet vacuum pump to open directly into the room to be extracted. This is particularly important for large halls or atriums.
  • the subclaims 7 to 10 show examples of the use of different gas or steam suppliers.
  • the use of jet engines will be preferred because of their availability, relatively simple assembly and their uncomplicated mobile use.
  • gas or steam suppliers already present in the vicinity of the structures, such as, for. B. to use a compressed air system or a steam generator.
  • the latter will be advantageous if there is a combined heat and power plant or a steam-powered electrical power generator in the vicinity of the building to be smoked.
  • a liquid gas system can also be installed or used as a mobile gas supplier.
  • Another decisive advantage of the system according to the invention is in that the parts of the system that are exposed to smoke and temperature in the event of a fire have no moving parts.
  • the jet engine or the other above Gas or steam suppliers come with the fire gases not in contact as it only works with the gas or steam jet vacuum pump via a supply line, in the case of the jet engine only via its Exhaust pipe, are connected. A decrease in performance through influence hot combustion gases therefore do not occur.
  • the gas or steam jet vacuum pump not additionally burdened by hot fire gases, since they is designed so that the hot exhaust gases from a jet engine withstand.
  • a permanently installed smoke and heat exhaust system also works independently of electrical utilities.
  • the Gas or steam supplier started up by a fire alarm sensor and then works independently. This ensures safety, smoke and Heat extraction systems must have over the fire development phase Be used effectively until the fire can.
  • smoke and Heat extraction system is the mobile use of one of its components or both components of particular importance. That has the advantage, that there is little or no expenditure on the building itself, z. B. only the duct system required for smoke and heat dissipation are. If, as protected in subclaim 10, a gas or steam supplier is in the immediate vicinity of the building, only the gas or steam jet vacuum pump is required. It needs no further explanation that in this case the connection between the gas or steam jet vacuum pump and the gas or Steam suppliers are only produced in the case of use. This can generally be the case with the mobile use of a smoke and heat exhaust system according to the invention so be provided. But it is also conceivable that the smoke and Heat extraction system as a complete system that can be used immediately station so that the connection of their two components before starting use can be omitted.
  • the mobile use of smoke and heat extraction systems has two more Significant advantages: It avoids flammable substances that are used for operation of the gas supplier, for example a jet engine, is required are to be stored in the immediate vicinity of the structure. To change can now also the structural systems that have no mechanical Smoke extraction, can be smoked in a short time. This also applies here already for the staiffy systems for the performance of what has been said: the mobile systems have compared to the mobile ventilation devices the fire brigade has a suction volume that is orders of magnitude higher.
  • Heat exhaust system consists in reducing the environmental impact due to toxic fire gases. That in its composition essentially Known exhaust gas from the engine usually contains significantly less toxic substances as a fire gas. This advantage is even more beneficial the use of inert gases or steam as blowing agents. By the high flow velocities become the toxic fire gases strongly swirled and diluted released into the environment.
  • the building depicted in Fig. 1 is of a structural shell 1 surrounded and consists of three floors 2.
  • Each floor has controllable Supply air openings 3, such as. B. windows, doors, ventilation flaps u.
  • Each floor 2 has fire detectors 4 and a duct system 5 on the ceiling installed, which opens into an ascending smoke exhaust duct 6. This is led out of the building in the roof area and there to the suction side a gas jet vacuum pump 7 connected.
  • the driving side of the Gas jet vacuum pump 7 is with the exhaust system of a gas jet engine 8 in connection, that of one in the drawing no closer shown tank is supplied with fuel.
  • the commissioning of the Gas jet engine 8 takes place via a control line 9, via which the Gas jet engine 8 is connected to a control device 10.
  • the control device 10 receives the signal required for this from the Fire detectors 4 via their signal line 11.
  • an atrium is shown symbolically, the surrounding gallery 12 and has a dome 13.
  • the smoke exhaust duct 6 is directly from the Dome 13 led out. All other designations were as in Fig. 1st used. In the event of a fire, the flue gases will be immediately below accumulate the dome 13. Due to the enormous suction volume of the invention The other areas, especially the Gallery 12, kept smoke-free.
  • the fire or fire alarm goes off at the fire brigade, which in addition to the extinguishing technology carries the mobile technology for smoke extraction according to the invention.
