DOUBLE ROTOR WIND TURBINE-EXTRACTOR ASSEMBLY

Abstract

The present invention relates to a double-rotor wind turbine extractor assembly for utilizing waste air for the generation of electrical energy, comprising a rotating axial-axis air extractor to which rotating extraction blades are radially attached, said axial axis being rotatably driven by a transmission system; said air extractor being housed in an internal cavity of an outer casing fixed to an external support structure; a conical diffuser partially housed and fixed in said internal cavity of said outer casing, in an opposite position to where said axial axis with the rotating extraction blades is arranged, and which defines a conical duct for concentrating and conducting the airflow expelled by said axial-axis air extractor;An electric power generator comprising a body that houses means for generating electric power and where a first set of front blades and a second set of rear blades, spaced apart from each other, are mounted with rotational capability, which rotate by the action of the airflow expelled by the axial shaft extractor, concentrated and channeled by said conical diffuser to produce electric power; said body of the electric power generator comprising in its central area between said sets of front and rear blades, a support structure with which it is fixed to the rear of said support structure of said axial shaft air extractor.
