New Water Powered Scrubber ? Objective

To clean coal mine air by developing a low-cost scrubber suitable for belt transfer and similar applications. Approach Design a scrubber operated by water only, with no moving parts. Use conventional water spray nozzles located within a duct to both move and clean the air. Use a droplet eliminator to get the water droplets and mist back out of the airstream. How It Works Conventional scrubbers require a mechanical fan driven by either an electric or a hydraulic motor. They also require water sprays and some type of scrubbing mechanism. The water powered scrubber, however, offers higher reliability over conventional scrubbers since it utilizes the water sprays to both move the air and scrub the particulate from the air. Conventional water spray nozzles are placed near one end of a rectangular duct open at both ends. The sprays are directed towards the far end of the duct where a stationary wave blade water droplet eliminator is located. Movement of the water spray droplets coming from the nozzles generates (by momentum transfer) an air movement In the same direction as the sprays. The volume of air moved Is primarily a function of the duct cross-section size, water pressure and water
