Waste battery recycling - 2012-10-23 19:34:17

Waste batteries small but great harm. Because the waste batteries pollution Unlike garbage, air and water pollution, as you can with the sensory feel it has a lot of hidden, so they did not get the attention they deserve. At present, China has become the major powers of the production and consumption of the battery, battery waste pollution is an urgent need to address major environmental issues. Simple recovery method used batteries, environment pollution, should take further measures.
1 Classification
Recycling of used NI-CD Rechargeable Battery smashed, the stripped zinc shell and the battery bottom of the iron, remove copper cap and graphite sticks, the rest of the black substance is a mixture of manganese dioxide and ammonium chloride as a battery core, the substances were concentrated collection after processing, can be obtained by some of the useful substance. Graphite rods by washing, drying and then used as the electrode.
2. System zinc tablets
After washing the stripped zinc shell placed in a cast-iron pot, heated, melted and incubated for 2 hours, upper dross is removed, pour the cooled drops in the iron on, to be solidified after the zinc particles.
3. Recycling copper
The flattened copper cap, washed with hot water, then add a certain amount of 10% sulfuric acid is boiled for 30 minutes, to remove surface oxide layers, remove and wash, drying ie copper.
4. Recovery of ammonium chloride
Place the black substance in the tank, and 60oC the warm water was stirred for 1 hour, so that ammonium chloride was completely dissolved in water, still, filtered, washed with water Residue 2 times, collected the mother liquor; in the vacuum distillation of the mother liquor to a white crystal film on the surface appears , cooled, filtered and ammonium chloride crystals, the mother liquor loop utilization.
5. Recovery of manganese dioxide
After filtration, the residue washed three times, filtered, and the cake was placed in the pot was evaporated to dryness to remove a little of the carbon and other organics, then placed in water and sufficiently stirred for 30 minutes, filtered, and the filter cake was dried at 100-110oC, ie black manganese dioxide
Reasonable processing of waste lithium battery collection will undoubtedly reduce the environmental risks of waste batteries with the city garbage collection, but the collection of waste batteries, storage, transportation, disposal and recycling of all aspects of the, if not managed well can produce local, more serious pollution problems.
