Definitions
- the present invention relates to a ventilation device for producing a driving force for producing electrical energy from air.
- the idea underlying the invention is to use the driving force caused by the rise of this hot air to generate electrical energy.
- the object of the invention is therefore to provide a device that allows forced driving of hot air so as to recover the driving force thus generated.
- the subject of the invention is a ventilation device for producing motive power intended to produce electrical energy, characterized in that it consists of a vertical air circulation duct of at least 100 meters in height in which is set up a turbine, the inlet of the lower part of the pipe upstream of the turbine being arranged to collect a useful volume of air while the upper part of the pipe downstream of the turbine is arranged to cause suction of the air collected in the lower part through the turbine, the outlet of the upper part of the pipe being further arranged to allow only an evacuation of the air and to prevent any air intake cold in the pipe.
- the air collected in the lower part of the pipe according to the invention is hot and therefore has a natural tendency to rise in said pipe, the upper part of the pipe further promoting this rise in the pipe causing a suction of the air exceeds the thrust of hot air, which avoids the phenomenon of compression.
- the device according to the invention advantageously uses two natural phenomena that are the difference in temperatures between two altitudes due to the very great height of the pipe and the action of the wind as for a wind turbine.
- the regularity of production is thus better since one can play on both factors.
- such a device can be envisaged in buildings such as high-rise towers to serve as an integrated power generation device. It is also possible to envisage installing a device according to the invention on a mountainside.
- the inlet of the lower part of the pipe upstream of the turbine of the device according to the invention has a conical shape and the lower part of the pipe extends to the turbine having a diameter D.
- This diameter D is defined according to the electric power to be equipped.
- the upper part of the pipe downstream of the turbine has a diameter of at least 1.5 x D while on the upper outlet of the pipe is provided a movable air shaft with a diameter of at least 3 x D, orientable in the direction of the wind and allowing only the evacuation of the air out of the pipe.
- the turbine may be a blade turbine, a tangential turbine or any other suitable turbine model.
- the device according to the invention comprises a vertical pipe 1 in which is housed a turbine 2.
- the inlet of the lower part 1a of the pipe 1 upstream of the turbine is arranged to collect a useful volume of air.
- the inlet of the lower part 1a of the vertical pipe 1 is made conically 3 while the pipe 1a upstream of the turbine 2 continues to the turbine 2 having a diameter D.
- a valve of regulation 6 can be provided between the conical inlet 3 and the lower part 1a of the pipe 1.
- the upper part 1b of the pipe 1 Downstream of said turbine 2, the upper part 1b of the pipe 1 has a diameter of at least 1.5 ⁇ D so as to cause the suction of the air from the lower part 1a through the turbine 2
- a movable air shaft 4 At the outlet of the upper part 1b of the pipe 1 is provided a movable air shaft 4 which can be rotated in the direction of the wind, for example by means of a fin 5, and whose diameter is at least 3 x D.
- the shape of this movable part 4 is adapted to evacuate the air from the pipe 1 and prevent the entry of cold air at altitude.
