DEVICE FOR DRAINING HUMIDITY IN WIND TURBINES

摘要

Device for draining humidity in wind turbines It is proposed a wind turbine (10), comprising: - at least one rotor blade (20), - at least one aerodynamic device (30) for influencing the airflow (71) flowing from the leading edge section (24) of the rotor blade (20) to the trailing edge section (23) of the rotor blade (20), wherein the aerodynamic device (30) is mounted at a surface (28) of the rotor blade (20), - a pneumatic actuator (33) of the aerodynamic device (30) for actuating the aerodynamic device (30) at least between a first protruded configuration and a second retracted configuration, - a pressure supply system (52) for operating the actuator (33) by means of a pressurized fluid, - a centrifugal device (60, 70) rotatable about a rotor axis (Y) of the wind turbine (10), the centrifugal device (60) comprising an air inlet (61) of receiving a flow of the pressurized fluid including humidity from the pressure supply system (52) and a water outlet (62) for letting a flow of condensed water to exit the centrifugal device (60).
