| 摘要 |
The invention relates to an apparatus and a process for taking up particles, in particular particles of oil, algae or dirt, from a water surface ( 2 ). A hull structure ( 1 ) is moved over the water surface ( 2 ). In this case, a flow ( 6 ) of water laden with particles is produced in the region of a bottom surface ( 7 ) of the hull structure ( 1 ). The flow ( 6 ) is broken away or interrupted along a vortexing edge ( 13 ) in the region of the bottom hull-structure surface ( 7 ), with the result that a vortex flow ( 14 ) is produced for at least some of the particle-laden water. The vortex flow ( 14 ) passes into a vortex flow space ( 15 ). With the aid of localizing means, the vortex flow ( 14 ) is localized in a separation section ( 23 ) of the vortex flow space ( 15 ), with the result that particles of the particle-laden water which are picked up by the vortex flow ( 14 ) can be separated from the separation section ( 23 ).
