This static vacuum cleaner 7 is mounted on the duct section 4 at its downstream end with respect to the direction of circulation of the gaseous fluids to be discharged and of drive. This means that the static vacuum cleaner 7 is, in the embodiment more especially considered, located in part upper end of the 4 in the upper extreme part of the duct section 4.
the static vacuum cleaner 7 can be of the statomechanical type rather than static.
the device 1 also comprises, thirdly, means 8 for injecting a gaseous drive fluid into the section of conduit 4 in the same direction as the direction of circulation of the gaseous fluid to be discharged.

the duct section 4 is an integral part of the static or statomechanical vacuum cleaner 7.
the duct section 4 is then constituted by the ferrule 25 which is provided with the vacuum cleaner 7.

peripheral nozzles 32 and median nozzles 34 are, in one embodiment, regularly distributed around the axis 4a, either discretely or continuously.
these nozzles 32, 34 can be arranged in the form of a crown.
the different nozzles 27, 31, 32, 34 are arranged with respect to one another so as not to substantially obstruct the passage of the gaseous fluid to be discharged which comes from upstream of the section of duct 4 and of the main duct 2 Indeed, it is desirable that the flow of gaseous fluid to be discharged is not too disturbed by the presence of the injection nozzles.
the injection nozzles 27 are arranged in rows and columns and are carried by a perforated plate located in the section of conduit 4 being carried by it.
This plate is either flat ( Figure 2f) or curved ( Figure 2g).
the device 1 generally comprises means for selective control of the operation of the different nozzles. In fact, it is not necessarily compulsory that all the nozzles operate continuously and in the same way.
the physical characteristics of the flow of gaseous drive fluid injected by the different nozzles 27 such as flow rate, speed or opening of the beam are identical or similar.
the flow rate and the speed may be greater for a central nozzle 31 than for a peripheral nozzle 32.
