Abstract
A recovery device for a volatile organic compound is a device for recovering the volatile organic compound in a coating drying oven which dries a coating film of a workpiece coated with a water-soluble coating. The coating drying oven includes: an evaporation zone in which moisture of the workpiece is evaporated; and a curing zone to cure the coating film. The recovery device includes: a first take-out passage for taking out first furnace air in the evaporation zone; a second take-out passage for taking out second furnace air in the curing zone; a mixing chamber configured to mix the first furnace air and the second furnace air to obtain mixed air; and a cooling recovery unit configured to cool the mixed air and recover, as a condensate, the volatile organic compound contained in the mixed air, together with the moisture.
