Device for separating overspray, surface treatment system and method for separating overspray

摘要

The present invention relates to an apparatus for separating overspray from an overspray-laden air stream passing through the apparatus, having a first separation region (92) and a second deposition region (94) downstream of the first deposition region (92). wherein the first separation region (92) has a pre-separation device (50), and wherein the second separation region (94) has a separation device (30), in particular an electrostatic precipitation device. The invention also relates to a surface treatment installation for objects (4) having a treatment booth (2) in which overspray is absorbed by an air flow, and to an apparatus for separating overspray with a separation device (30), in particular an electrostatic precipitation device (30), a pre-separation device (50) is arranged upstream. The present invention also relates to a method for separating overspray from an air stream, wherein the air stream is passed through a pre-separation device (50) after it has flowed through a treatment booth (2) before it reaches a downstream separation device (30), in particular an electrostatic precipitation device (30 ) to be led. The invention reduces the contamination of the separation device (30) and increases their reliability during operation. As a result, business interruptions are reduced and the surface treatment plant can be operated more efficiently.
