This invention provides an improved method and apparatus for collecting a liquid overspray from a gaseous mist and separating the liquid from the gas stream. The invention has utility in a wide variety of chemical application processes such as to reduce the hazards and waste characterized by prior art methods and provide a mechanism for the in-line recycling of the overspray liquid. In a preferred embodiment, the present invention comprises a hooded recovery unit which is oriented above and about a conveyor system in which a workpiece travels through a spray zone in which a chemical or other liquid is applied to the workpiece. In such a situation, the present invention provides for the recovery of overspray liquid which would otherwise be wasted as the liquid or chemical is applied to the workpiece during the period in which the workpiece passes through the recovery unit. The system includes a spray application chamber, a conditioning chamber, and an overspray collection chamber. The overspray collection chamber functions by means of a series of evase wicking baffles oriented such as to turn the entrained air. Furthermore, the repeated transfer of the gas between sections of low velocity and sections of higher velocity at a controlled temperature near the condensation point serves to effectively separate the chemical from the air stream.
