  • Waste Gas Processing Device, Vacuum Coating System, and Operation Method of Waste Gas processing Device
    Publication number: 20190388837
    Abstract: Provided are a waste gas processing device, a vacuum coating system, and an operation method of a waste gas processing device. The waste gas processing device is configured to remove and recover arsenic in waste gas, and includes a condensation portion and a scraping portion. The condensation portion is provided with a condensation cavity, and an air inlet, an air outlet and a discharge port communicated with the condensation cavity. The condensation portion is configured to cool waste gas charged into the condensation cavity from the air inlet, so that gaseous arsenic in the waste gas is condensed on an inner wall surface of the condensation cavity by cooling to form solid arsenic. The scraping portion is rotatably provided in the condensation cavity, and a partial surface of the scraping portion abuts against the inner wall surface of the condensation cavity.
