SEAWATER URANIUM EXTRACTING DEVICE UTILIZING OCEANIC CURRENT AND WAVE POWER

摘要

PURPOSE:To efficiently adsorb uranium in seawater on an adsorbent and to extract uranium by arranging plural hung pipes provided with many basket bodies having an opening for the uranium adsorbent to go in and out in seawater, and utilizing an oceanic current and wave power. CONSTITUTION:Plural floats 1 are arranged at regular intervals on the sea by a connecting rope 2, a long hung pipe 3 of rubber, etc., with the upper end opened on the upper surface of the float 1 as the entrance 4 for the uranium adsorbent is hung from each float 1, and many basket bodies 5 are skewered on the hung pipe 3 to form plural adsorption beds. Four openings 8 are provided to the basket body 5, and a damper 9 free to open and close is fixed to the upper edge. The uranium adsorbent is injected into the adsorption bed of each basket body 5 by the sand pump of a marine working boat, and uranium is extracted. The adsorption bed of the basket body 5 is vertically oscillated even by a low wave, the damper 8 is one-sidedly opened and closed by seawater energized by the oceanic current and wave power to pass seawater, the uranium in seawater is continuously adsorbed on the adsorbent in the adsorption bed, and uranium is desorbed and recovered on the working boat. The adsorbent after recovery is again supplied to the adsorption bed, and used for adsorbing uranium.
