It plants recuperation of impurities and valuable elements from electrolytes to rule out, based on a bipolar cell, of permeable electrodes, ínter spaced by the distances of equilibrium

Abstract

An electrochemical cell polar type is used like mechanism recuperator of impurities and noble species, from contaminated or impoverished electrolytes. The fluid to treat is made circulate through perforated electrodes or of type mesh, of stainless steel, titanium, platinum, receive or another substance, by means of pumps, with the purpose of producing successive, selective deposits of the different chemical substances. These electrodes are located to inter spaced by calculated specific distances. The longitudinal coordinates of each electrode calculate and control by means of a planimetric algorithm of the electric field, that appears between the terminal electrodes, anode and cathode, polarized by an outsourcing of tension. The size and the number of electrodes of the cell filter are determined based on the time of residence required by the flow to process, in order to obtain a global yield of optimal recovery to the volume, its composition and concentration of impurities and noble species. As first task a computacional system elaborated the planimetry of the electric field, deriving the equipotential surfaces. Then is possible to predict the behavior of the electrical charges in the sine electrolyte and zones of interfaces electrolyte - electrodes and to derive a set that describes its dynamics as opposed to the imposed electromagnetic field, from such form that is developed to the potentials required in each electrode for him selective deposit of species. This intelligent filter is used for ample phantoms of contaminated metallurgical riles mining with active dangerous impurities, or solutions of discarding that can contain valuable elements, being able to be used on effluents of flows and normal conditions in the productive activity.
