摘要： An anti-pollution ventilation system includes means for circulating a fluid in a closed-loop path outside of a spray-type coating chamber. The circulating fluid is directed so as to form a fluid curtain across entrance and exit openings of the coating chamber. The system also includes a separator for continuously separating coating material from the circulating fluid. The separator comprises a plurality of side-by-side bores, having helical baffles therein, through which circulating fluid is directed. In one embodiment of the invention, some of the bores can be selectively closed. Means are included for transporting separated coating material from the separator back to the coating chamber for reuse. One refinement of the invention is to provide a bleeding means for bleeding fluid from the ventilation system, and another refinement is to provide a leakage collecting means for collecting leakage from the fluid curtains; in both cases a vapor-contaminant cleaner is provided to clean drained or leaked fluid before it is released to outside atmosphere. The ventilation system of this invention is further disclosed in combination with an irradiation type coating device wherein a coating chamber and an irradiating oven are located so close to one another that their inner atmospheres can mix. The inner atmospheres comprise mainly inert gases. In this embodiment, inert gas is bled from the ventilation system and fed to the irradiation oven.
