Abstract

The invention discloses an environment-friend recycle processing method of waste lead-acid accumulator, comprising that first separating acid solution of waste lead-acid accumulator, using breaker to break waste lead-acid accumulator, using selector to select the broken mixture, processing following treatment on metal lead, relative oxide and lead plate grid particles, feeding metal lead and relative oxides into a band filter to filter out water and obtain lead mud, putting lead mud into a furnace to obtain rough lead, putting rough lead into a fining furnace, to remove foreign materials to obtain pure lead, putting lead plate grid particles into an alloy furnace, to adjust the components of alloy until qualified, using casting machine to cast lead alloy into lead alloy ingot, using smoke recycle processor to recycle the smoke and dust generated in furnace. The invention smelts and recycles plastic casing, PVC baffle plate, metal lead, and plate grid alloy of waste lead-acid accumulator according to different physical and chemical properties, with environment-friend property, which can repeatedly recycle resource.

Description

technical field [0001] The invention belongs to the field of metallurgy, and in particular relates to the recovery and treatment technology of lead alloys, in particular to the recovery and treatment technology of lead alloys in waste lead-acid batteries, and in particular to an environmentally friendly recovery treatment method for waste lead-acid batteries. Background technique [0002] At present, the positive and negative grids of lead-acid batteries use lead alloys, such as lead-calcium multi-element alloys and low-antimony alloys. Lead-acid batteries have a certain service life. After lead-acid batteries are scrapped, lead alloys are difficult to handle and easily pollute the environment. Contents of the invention [0003] The object of the present invention is to provide an environmentally friendly recycling and processing method for waste lead-acid batteries, which solves the problem that lead alloys in waste lead-acid batteries in the prior art are difficult to ha...
