Treatment technology used batteries.
At present, the treatment of waste batteries mainly have 4 kinds: artificial sub-ringworm dry, wet and dry.
1 manual sorting: the first classification, artificial sub-elected carbon rod, copper caps, zinc and various remnants of skin, and separately with the corresponding measures to deal with, this method is simple, but many workers, the economic benefits bad.
2 do law: also known as smoke or fire law, is the classification of used batteries ringworm broken screen, the Add roaster at 600-800 ℃ under Medium roasting, gas condensate will be discharged after the check of mercury, and then roasting residues released into the rotary kiln at 1100-1800 ℃ under calcination, from flue gas Recycling zinc oxide, the residue recovered from the manganese and iron. Transportation method, generally there is no need to increase the smelter equipment and labor, can be dry-cell batteries Recycling of zinc, if have to further the recovery of other substances, equipment must be increased.
3 Wet: Dry Batteries classification is broken, the place leaching tank, add dilute sulfuric acid for leaching, and then filtered from the filtrate to extract metals zinc, copper dregs isolated metal cap, and then from the residual mud residue further to extract manganese. This method can make use of existing zinc hydrometallurgy plant equipment and technology, of used batteries for recycling.
4 dry law: that is, do, combining the advantages of wet, use the method of roasting Recycling of mercury and some zinc, and then leaching and electrowinning method of recovery of manganese and zinc remaining. Transportation method, recovery results were good, but more complicated processes, higher cost.
In recent years, sanitation and environmental protection department's call for volunteers and organizations, the Beijing Municipality has resulted in waste battery recycling outlets. Although battery recycling outlets in Beijing fundamental way, but the outcome is not significant. According to statistics, from May 1998 to May 1999, the Beijing Municipal Recycling used batteries total 14 tons, with the city's annual consumption of 6,000 tons as compared to minimal.
