Abstract
Official abstract text for this publication.
A wind turbine comprising a pod and an aerodynamic rotor having a rotor head or a spinner. The rotor head or spinner is arranged in that case in the afflux flow direction of the wind in front of the rotor blade plane. Provided in or at the rotor head or the spinner of the rotor is a mist eliminator which rotates with the rotor head or spinner. The mist eliminator has an end which is in the form of an opening in the rotor head or the spinner. Air can enter through that end and flow through the mist eliminator in such a way that substantially water droplet-free air is present at the outlet of the mist eliminator, and can be used for cooling the generator.
First claim
Opening claim text (preview).
The invention claimed is: 1. A wind turbine, comprising: a rotor having three rotor blades and a rotor head; and a mist eliminator in a region of the rotor head, the mist eliminator being configured to allow outside air to flow into an interior of the rotor head, wherein the mist eliminator has a first end and a second end, wherein the first end of the mist eliminator forms an opening of the rotor head, and wherein the mist eliminator has at least one slat of a spiral-shaped configuration. 2. The wind turbine according to claim 1 wherein the spiral-shaped configuration of the mist eliminator is of a conical configuration. 3. The wind turbine according to claim 1 wherein the mist eliminator has a spiral tip at the first end or the second end. 4. The wind turbine according to claim 3 wherein the mist eliminator has an inner region at the first end, wherein the inner region at the first end has a greater gradient than a remaining portion of the at least one slat to transport separated liquid to the spiral tip at the first end. 5. The wind turbine according to claim 1 , further comprising: a wall in an inner region of the second end. 6. A method comprising rotating the rotor head of claim 1 to allow the outside air to flow through the mist eliminator and into the interior of the rotor head, wherein the mist eliminator removes water from the outside air before providing the outside air to the interior of the rotor head.
