Embodiment 1
Waste and old lead acid accumulator is handled using the processing system of the lead-acid battery of the embodiment of the present invention, specific method
It is as follows：
(1) waste and old lead acid accumulator is subjected to Mechanical Crushing sorting using crushing-separating apparatus, obtain lead plaster and grid and
Plastics, wherein the main chemical compositions (butt, wt%) of lead plaster and grid are as shown in table 1.
1 lead plaster grid main component such as following table of table：(%)
| Title | Pb is total | PbO | Pb02 | PbSO4 | Sb | Pb amount of metal |
| Grid | 92-95 | It is micro- | It is micro- | It is micro- | 3-8 | 92-95 |
| Lead plaster | 65-80 | 15-20 | 20-25 | 25-35 | 0.5-1.0 | It is micro- |
(2) lead plaster after separation is used carbonate by PbSO by pre- desulfurizer4It is converted into PbCO3, the lead after being converted
Cream.
(3) top blast is added by skip bucket vehicle after dispensing together with lime stone, fluorite, iron filings, coke in the lead plaster after conversion
Converter carries out melting.By top-blown converter burning spray gun control fusion process in furnace gas oxygen gesture, 1100~1250 DEG C into
Row oxidation or reduction reaction, obtain lead bullion.
(4) lead bullion that melting generates enters kier by alloy steamed stuffed bun handling, using natural gas carry out indirectly heat to 320~
350 DEG C of refining crude leads, surface scum, and output lead bullion are removed in fishing after a certain period of time for reaction.
Simulation calculating is carried out to entirely refining splicer's skill, the lead bullion of generation is averaged lead tolerance by metallurgical software for calculation METSIM
It is 99.06%, the rate of recovery of lead is up to 99%, and the comprehensive energy consumption of lead bullion per ton is about 95 kilograms of mark coals.Obtained smelting slag and
Smoke components are as follows：
It can be seen that by above-mentioned data, the clinker leaded 2% generated after the completion of melting, SO in flue gas2Content is 2.649%.
And smelting technologies, the lead-in-dreg such as reverberatory furnace, blast cupola that reviver factory domestic at present uses are up to 11%, flue gas SO2
Content is about 10%.Therefore waste and old lead acid accumulator is handled using the processing system of the lead-acid battery of the embodiment of the present invention,
