Abstract
The invention discloses a formation charging desulfurization recycling new technology of a waste lead storage battery. The technology is characterized by comprising the following steps: breaking a waste battery and sorting the grid, lead, diachylon, battery case and separator paper; washing the diachylon solid slag and pressing into a briquette; performing formation charging desulfurization to obtain Pb, PbO2 and electro-hydraulic H2SO4; filtering and concentrating the electro-hydraulic H2SO4 for reuse; drying the Pb and PbO2; and catalyzing the Pb and PbO2 by the mixed gas of nitrogen and hydrogen to obtain lead oxide, wherein the lead oxide can be reduced by coke to obtain lead. Through the technology, active substances of the waste lead storage battery are directly converted into lead oxide which is directly used for preparing diachylon to produce a battery; without a smelting link, huge energy consumption in the existing electrolytic lead smelting process is saved, and the production cost of the lead storage battery is remarkably reduced; and meanwhile, the discharge of lead smoke, lead dust and SO2 is reduced to realize energy conservation, emission reduction and environmental protection, and the recovery rate is up to 99.5%. Therefore, the technology is the most ideal recycling technology.
