Device for separating paint overspray

A device for separating paint overspray from the exhaust air, laden with overspray, of a booth of painting plant, having

• a) at least one separating surface along which a booth exhaust air can be guided and which is connected to a first pole of a high-voltage source;
• b) an electrode means which is arranged in the booth exhaust air and is associated with the at least one separating surface and is connected to a second pole of the high-voltage source;
• and,
• c) means which can be used to transport paint overspray that is separated off away from the separating surface,
• wherein
• d) the means for transporting away the paint overspray from the separating surface include a separating liquid which flows downwards over the separating surface;
• and, wherein
• e) a discharge means is provided which has an upwardly open channel out of which separating liquid supplied thereto flows along a longitudinal extent thereof when the level of separating liquid in the channel exceeds an outflow level and reaches the separating surface in such a manner that the separating liquid on the separating surface flows down as a largely cohesive film,
• wherein the discharge means includes a drainage surface which is associated with the channel and runs parallel thereto and over which the separating liquid flows out of the channel laterally in the direction of the separating surface, and
• wherein the drainage surface has a first section which is inclined outwards and upwards and merges into a second section which runs in a horizontal plane.
