Description
Technical field
The present invention relates to a kind of processing sides of positive plate lead paste in lead-acid accumulator field more particularly to waste lead acid battery
Method.
Background technique
In view of the high-performance that lead-acid battery has been found, low cost, easily recycling and reliable safety, it is at present in the whole world
In the range of be widely used currently, the yield of western developed country reviver accounts for the 65% of lead total output, in U.S.'s height
Up to 76.2%.And developing country is then lower than 30%, and there was only 17% in the 06 year recycling lead in China.2/3 or more in lead-acid accumulator
Lead be that can recycle, and from recycling lead of abandoned lead acid accumulator lower than primary lead production cost 1/3 or so, with recycling skill
The development of art, either reducing cost and reducing on environmental pollution has great progress.From scrap lead there are mainly two types of at present
Acid accumulator returns lead technology: one is thermal process recycling, another kind is that dry and wet is used with to the Whote-wet method metallurgy developed later.Fire
Temperature of smelting furnace is high when method processing, generates a large amount of lead steam and SO2, seriously pollutes environment, energy consumption is high, but low in cost.It is wet
Method smelting is of reduced contamination relative to dry smelting, eliminates lead dust and SO2, but process is complicated, and there is also a large amount of pollutions
Link.Two kinds of smelting processes all smelt the active material in old and useless battery at electrolytic lead, are converted by electrolytic lead by ball milling
At the lead powder of 70-80% oxidizability, huge energy is consumed, and has lost other materials.
Summary of the invention
In order to solve the above-mentioned technical problems, the present invention provides in a kind of waste lead acid battery
The processing method of positive plate lead paste, includes the following steps,
The first step, dissection, separation, dissects waste lead acid battery, positive plate is separated with negative plate and partition；
Second step, cleaning, separation, cleans positive plate, after positive plate is at faintly acid, by the grid of positive plate and
Active material brown lead oxide is separated；
Third step, dry, grinding will be ground after brown lead oxide drying, and it is 0.1-50 μm two that processing, which reaches 80 ~ 90% partial sizes,
Lead oxide；
Brown lead oxide is heated to 150-300 DEG C, and removes fiber, water impurity by the 4th step, heating, decontamination；
Further, by the brown lead oxide be added inside lead powder, be added with purpose square graphite,
Stannous sulfate, antimony oxide, red lead, fiber, sodium sulphate, acid amount, water.
Further, the brown lead oxide additive amount is gross activity amount of substance 3%-20%.
Further, graphite 0.2-0.5%, stannous sulfate 0.3-1.5%, antimony oxide
0.1%-1.5%, red lead 3%-10%, fiber 0.1%-0.5%, sodium sulphate 0.2%-1.5%, acid amount 2%-5%.
Further, later, mixing paste, coated plate, chemical conversion are passed through to the lead powder.
Positive plate lead paste is able to achieve free of contamination processing in battery of the present invention and recycling uses.
