Abstract
Abstract In a painting system comprising 1. A PAINTING ZONE (A) with a feed air stream and an exhaust air stream containing vaporized organic liquid from the drying of the paint in zone (A), and 2. A PAINTING ZONE (B) with a feed air stream and an exhaust air stream containing vaporized organic liquid from the drying of the paint in zone (B), the improvement comprising means for routing exhaust air stream from painting zone (A), in an amount up to the total amount of exhaust air stream from painting zone (A) into the feed air stream for painting zone (B), and decreasing the volume of the original feed air stream for zone (B) by an amount up to the amount of the exhaust air stream from zone (A) that is routed into the feed air stream for zone (B). The invention is useful in reducing the volume of air exhausted from the painting system. Consequently, if such exhausted air must be treated with air pollution control devices, there results a reduction in the cost of the air pollution control devices and their cost of operation.
