Electrocell method and apparatus
This invention consists of an apparatus including an electrocell and, preferably, also a diaphragm pump for processing waste materials and recovering metals therefrom. The electrocell comprises a set of coaxial cylinders with end housings to maintain spacing. The innermost cylinder is a cathode. Surrounding the cathode is a porous barrier, then an anode and finally an outer shell. Interior to the cathode is a cathode coolant passage. Between the cathode and the porous barrier is a passage for a catholyte. Between the porous barrier and the anode is a passage for an anolyte. Exterior to the anode but inside an outer shell is a passage for the anode coolant. The passage for the anolyte is dimensioned, based upon the flow rate of the anolyte, to produce fully turbulent flow, preferably with a Reynolds number in excess of 4000. The diaphragm pump surges anolyte into the anolyte passage to further increase turbulence, thereby increasing the efficiency of the apparatus.
