Benefits of technology
The patent describes a device that separates paint from air using a regeneratable surface filter, which eliminates the need for a washing station and water treatment. This reduces energy consumption and space requirements for the device. Additionally, the device has an air circulation cycle that re-delivers exhaust air to the application area, which further saves energy.
Problems solved by technology
Known washing plants have the disadvantage, however, in particular with air circulation control, in that a high amount of moisture is supplied to the exhaust air flow from which the wet paint over-spray is separated, so that the exhaust air flow resulting after separation of the wet paint over-spray must be subjected to a energy-intensive dehumidification.
Furthermore, greater expense is required for the treatment of the washing liquid loaded with the wet paint over-spray.

Embodiment Construction
[0077]An installation shown in FIGS. 1 to 7, marked 100 as a whole for the spray-coating of vehicle bodies 102 which includes a clearly schematically represented conveyer device 104, by means of which the vehicle bodies 102 can be moved along in a conveying direction 106 through an application area 108 of a painting booth marked 110 as a whole.
[0078]The conveying device 104 can, by way of example, be constructed as an inverted circular conveyer or as an inverted monorail conveyer.
[0079]In particular the conveyer device 104 can be formed in two parts and—as best understood from FIGS. 1, 3 and 4—includes two conveyer belts 104a and 104b extending parallel to the conveyer 106, which are spaced apart from one another in a horizontal direction perpendicular to the conveyer 106.
[0080]The application area 108 is the interior chamber of painting booth 110, which perpendicular of it to the conveyer 106, which corresponds to the longitudinal direction of the painting booth 110, it is limited,...

Abstract
The invention relates to a device for removing wet paint overspray from an outgoing air flow (120) containing over-spray particles. The device separates wet paint over-spray from an over-spray particle contained in an exhaust air stream (120). The overspray particles in the exhaust air stream (120) are formed during the painting at an application area (108) of a painting installation (100). The device (126) comprises of at least one separation apparatus for separating the over-spray from the exhaust air stream (120). The separation apparatus includes a regeneratable surface filter (146) and the flow path of the exhaust air stream (120) from the application area (108) to a separating device (145) having at least one narrowed area (146). The central direction of flow of the exhaust air stream (120) remains essentially preserved in passing by the narrowed area (140).
Description
PRIOR APPLICATIONS[0001]The present application is a continuation of U.S. patent application Ser. No. 11 / 886,764 filed on Jan. 23, 2009, which is a National Stage of, and claims priority to and all advantages of International Patent Application No. PCT / EP2006 / 002469 filed Mar. 17, 2006, on the basis of German Patent Application No. DE10 / 2005 / 013711.3 filed on Mar. 24, 2005.TECHNICAL FIELD[0002]The present invention relates to a device for removing wet paint overspray from an exhaust air flow containing over-spray particles, whereby the over-spray particles in the exhaust air flow reach into an application area of a painting installation.TECHNICAL BACKGROUND[0003]Such devices are used in plants for painting work parts, in particular for spray-painting vehicle bodies, in which an air flow is produced by an application area of the plant, which exhausts excess wet paint from the application area.[0004]It is well-known to separate out the carried wet paint over-spray of a washing plant f...
