The invention relates to a mechanical smoke and heat evacuation system for removing smoke from structural works, for example, from buildings and tunnels, among other things, in order to make it possible for people to escape from areas containing smoke and heat and/or harmful gases or aerosols as well as making it possible for rescue workers to enter these structural works or to permit the fire department to carry out a targeted extinguishing offensive. The aim of the invention is to create a mechanical smoke and heat evacuation system which is comprised of a suction pressure generator and of a power supply and whose operation is ensured independent of the amount of smoke and heat produced by the fires. The system should consist of robust components which are insensitive to temperature, smoke and other harmful substances. In addition, the system should offer a higher suction volume per unit of time by order of magnitude. According to the invention, a gas jet or steam jet vacuum pump (7) is provided as a suction pressure generator whose impelling side is connected to a gas or steam supplier. A gas jet propulsion mechanism (8) can be used, for example, as a gas supplier. The system can be operated in both a stationary as well as mobile manner.
