The invention relates to a device for removing wet paint overspray from an outgoing air flow containing over-spray particles. The device separates wet paint over-spray from an over-spray particle contained in an exhaust air stream. The overspray particles in the exhaust air stream are formed during the painting at an application area of a painting installation. The device comprises of at least one separation apparatus for separating the over-spray from the exhaust air stream. The separation apparatus includes a regeneratable surface filter and the flow path of the exhaust air stream from the application area to a separating device having at least one narrowed area. The central direction of flow of the exhaust air stream remains essentially preserved in passing by the narrowed area.

The disclosure relates to an operating method for a coating system, in particular for a painting system, for coating components (2), in particular motor vehicle body components (2), having the following steps: conveying, by means of a conveying device (3), the components (2) to be coated in a conveying direction through a coating booth (1), coating the components (2) in the coating booth (1) with a coating product by means of an application device (17-19) which applies a spray jet of the coating product, a portion of the applied coating product being deposited on the components (2) to be coated while another portion of the applied coating product floats into the interior of the coating booth (1) as an excess coating product mist (21), and reducing the excess coating product mist (21) from the interior of the booth by means in addition to or other than the downwardly directed air flow generated by a filter ceiling. In addition, the disclosure includes a correspondingly designed coating system.

The invention provides methods and compositions for a composition and/or a method for treating impurities in a circulating water system. The circulating water system impurities may be oversprayed paint in paint spray booth applications. The composition includes an aqueous solution of a cationized starch, a polybasic aluminum salt such as aluminum chlorohydrate or polyaluminum chloride and a solution of a medium to high MW aqueous flocculant. The composition is particularly useful when added to recirculating scrubber water in paint spray booths for effectively treating both water based and solvent based paints.

A painting booth may include: a painting chamber and/or an overspray removal unit. Paint may be sprayed in the painting chamber. The painting chamber may be crossed by an air flow for evacuation of overspray from the painting chamber. When exiting the chamber, the air flow may pass through the overspray removal unit in order to remove the overspray from the air flow. The overspray removal unit may include an incoherent mass of cleaning elements kept in a stirred condition, through which the air flow containing the overspray passes so as to release the overspray onto the cleaning elements. A method for removing overspray from air flow exiting a painting booth may include: passing the air flow through an incoherent mass of cleaning elements which are kept in a stirred condition, so as to release the overspray onto the cleaning elements of the incoherent mass.

An exhaust configuration for a wet scrubber. The exhaust configuration includes a diffuser that is attached to the wet scrubber and which defining an outlet for discharging scrubbed air and paint laden water from the wet scrubber. Attached on lateral sides of the diffuser are wings. The wings extend away from the outlet.

The present disclosure relates to purge fluids, methods of using the purge fluids, and systems to be used for recycling the purge fluids. In some aspects, the purge fluid may be used to clean or purge an automated spray coating apparatus, such as a paint gun. The purge fluid may include a solvent and water. After the purge fluid is utilized for purging or cleaning certain system components, the purge fluid may be treated, subjected to a liquid-solid separation technique, and reused as a purge fluid.

A spray booth module having a plurality of wet scrubbers. The wet scrubbers being located beneath an area where over spray is generated and enabling the under section exhibits a reduced vertical depth relative to known under sections of comparable spray booths.

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).
