Device for draining humidity in wind turbines

A wind turbine comprising:

• at least one rotor blade;
• at least one aerodynamic device for influencing an airflow flowing from a leading edge section of the at least one rotor blade to a trailing edge section of the at least one rotor blade, wherein the at least one aerodynamic device is mounted at a surface of the at least one rotor blade;
• a pneumatic actuator of the at least one aerodynamic device for actuating the at least one aerodynamic device at least between a first protruded configuration and a second retracted configuration;
• a pressure supply system for operating the pneumatic actuator with a pressurized fluid;
• and
• a centrifugal device rotatable about a rotor axis of the wind turbine, the centrifugal device comprising an air inlet for receiving a flow of the pressurized fluid including humidity from the pressure supply system and a water outlet for letting a flow of condensed water to exit the centrifugal device,
• wherein the centrifugal device comprises a water outlet valve at the water outlet positioned between the at least one aerodynamic device and a tip section of the at least one rotor blade.
