PURPOSE: To provide a winning device for uranium from sea water which enables the uniform contact of the sea water and adsorbents by fitting an air tank to an adsorption device disposed with an adsorption zone and a settling and sepn. zone and providing of mooring means for the device in the sea surface.
CONSTITUTION: An adsorption zone 3 is provided on the upstream side of ocean current and an adsorption and separation zone 4 is provided on the downstream side thereof in the adsorption unit 2 of an adsorption device 1. Slurry-like adsorbents are ejected from spray nozzles 5 in the zone 3 and are uniformly flowed in the sea water. The adsorbents deposited on the tray-like deposition bed 9 in the zone 4 are accumulated in a accumulating channel 10, whereafter the adsorbents are sucked up by a piping 11 so as to be fed again to the zone 3 and are cyclically used. Air tanks 14 having buoyancy are provided to the front and rear of the device 1 to float the device on the sea surface. The device is moored by means of a mooring buoy 15 and mooring lines 16. The handling of the adsorbents is made easy by such device and the uranium in sea water is efficiently won.
