THE SMALL WASTED SAFE ECOLOGICAL COMPLEX OF SPENT LEAD-ACID BATTERIES
Work is devoted to the study more ecologically clean electrochemical technology of lead-acid processing accumulators in electrolytes on the basis of silicic fluorine hydrogen acid. The complex chart of lead contained processing of components of accumulators, including the separation of accumulator sludge its, grinding, desulphatation, dissolution by suitable reagent for this purpose, is proposed, and electric dissolution of preliminary desulphated of plates in the received electrolyte after introduction of additional components, allowing to improve its operating properties. Influence of lead salt concentration, of silicic fluorine hydrogen acids, different acid substances in an electrolyte on the electrolysis parameters and processing speed has been considered (tolerable cathode density of flow, speed of lead sludge and accumulator plate's dissolution, cathode and anode outputs along the flow, anode output product). Composition of electrolyte, in terms of rational ecology and technology has been selected.
