Description

Waste lead-acid storage battery and lead-containing waste regenerated and reduced lead ingredient and preparation method thereof

Technical Field

The invention relates to the field of lead-zinc smelting secondary lead metallurgy, in particular to a waste lead-acid storage battery, a lead-containing waste material regeneration reduction lead ingredient and a preparation method thereof.

Background

The lead-containing waste materials comprise lead mud, lead paste and waste polar plates after the disassembly of the waste lead-acid storage battery, and are waste materials containing lead and lead compounds (PbSo4, PbO, PbS, Pb and the like). The waste (main material) is mixed with auxiliary materials (scrap iron, coke powder or white coal, etc.) and then added into a smelting furnace together to generate the reduced lead through high-temperature oxidation-reduction reaction. The raw materials added into the smelting furnace generate a slag layer after a series of high-temperature chemical reactions and are separated from the produced lead, the lead is in a lower layer due to high density, the slag is in an upper layer due to low density, and the slag in the upper layer is removed to obtain the lower layer of reduced lead (crude lead).

The slagging and redox reactions in the smelting furnace are as follows: fe + S → FeS, Fe + O₂→FeO，PbSo₄→PbO+SO₂，PbO+C→Pb+CO₂. The iron filings only play a role in fixing sulfur and slagging, the iron oxide and gangue components in the raw materials form an Fe-Si-Ca slag system, and C plays a role in reducing.

In the prior art, the iron filings are added according to the amount of water and lead compounds contained in the main materials, the iron filings added when the lead plaster contains water and So 4-with more components are up to 20%, and the iron filings added to the polar plate are at least 9%.

Therefore, the prior art has the following disadvantages when the waste containing lead and lead compounds is subjected to oxidation reduction:

the disadvantages are: the cost is enormous. Because the amount of the added scrap iron is high, the economic cost is increased, so that the enterprise runs at high cost for a long time, the scrap iron consumption amount is up to 20 tons in terms of processing 100 tons of lead plaster per day, and the scrap iron price per ton is 2900 yuan, so that the daily cost is increased by nearly 6 ten thousand yuan.

The defect is that: the energy consumption is high. In advance, the scrap iron is well participated in the reduction and slagging reaction and must be melted, and the heat energy consumption of 20 tons of scrap iron every day is equivalent to the consumption of more than 2.5 tons of standard coal.

The defect is that: the yield of the reduction process decreases. Because the amount of the slag after smelting is high due to the high amount of the added iron filings, the lead taken away from the slag is increased, the lead content of the slag is kept unchanged by taking 1.5 percent of the lead in the slag as an example, and the direct yield is reduced by 15 kilograms when the amount of the slag is increased by one ton.

Disadvantage iv: the iron chips are in a strict market supply and the price is high. The scrap iron only comes from the iron piece processing industry, and is a leftover material of a lathe in the iron piece processing industry for shoveling, planing and turning in the processing process, and the scrap iron is used in a large amount, so that the price of the scrap iron is high.

When the scheme of the embodiment 1-3 is adopted, the method has remarkable effects and advantages that:

1. the addition amount of scrap iron in the fourth ingredient is reduced due to the change of the formula and the feeding time of the fourth ingredient, and the huge cost expenditure is reduced:

for example: in the prior art, more than 14 percent of scrap iron is required to be added for the smelting of the lead plaster, the technology of the invention only needs to add about 3 percent, and the cost can be saved by calculating the year of processing 100 tons of lead plaster per day:

100 ton/day x (14-3)% × 2900 yuan/ton x 300 day/year 957 ten thousand yuan/year.

2. The amount of discharged slag is reduced by more than 10 percent (raw material ratio) due to the change of the formula and the feeding time for controlling the fourth ingredient, and the disposal cost of hazardous waste is reduced.

After scrap iron blended in lead plaster smelting is reduced from 14% to 3%, the amount of slag discharged from the furnace is reduced by 11%, and the cost can be saved in the year by calculating the 300 yuan disposal cost of disposing 1 ton of slag (dangerous waste) per commission at present:

100 ton/day x (14-3)% × 300 days/year x 300 yuan ═ 99 ten thousand yuan/year.

3. The amount of the slag is reduced due to the change of the formula and the feeding time for controlling the fourth ingredient, so that the loss of valuable metals from the slag is reduced, the recovery rate of the valuable metals is greatly improved, and the valuable metals can be recovered: in the prior art, the lead content in the slag generated by scrap iron mixed in lead plaster smelting is 1.5 percent (the requirement of the Standard conditions of the Secondary lead industry), and in practice, most enterprises can hardly reach 1.5 percent at one time, generally between 1.0 and 4.5 percent, and a 1.5 percent value is obtained for unified calculation. The invention reduces the slag amount due to the change of the formula and the mode, thereby improving the valuable metal amount:

lead content of 49.5 ton/year, 100 ton/day x (14-3)% × 300 day/year x 1.5%

49.5 tons/year × 13000 yuan/ton equals 64.35 ten thousand yuan/year.

4. The energy consumption is greatly reduced due to the formula and the change of the feeding time of the fourth ingredient.

Compared with the method, the method has the advantages that the iron filings are added in the lead plaster smelting pre-mixing way by 11 percent in the prior art, the iron filings are saved by the method: 100 ton/day x (14-3)% -11 ton. The prior art needs to melt the 11 tons of iron filings to 1200 ℃, and consumes a large amount of heat energy.

According to the experience, 100-130 kg of coke (120 is taken for convenient calculation) is needed for melting 1 ton of scrap iron, and the calorific value of 1 kg of coke is 30000000 joules.

The annual energy consumption is as follows:

100 ton/day x (14-3)% × 120kg coke/ton x 30000000 joule 39600000000 joule/day.

39600000000 joules/day × 300 days 1188000,0000000 joules.

The calorific value of 1 kilogram of standard coal is 29307.6 kJ. The standard coal can be saved in the year:

405.36 (ton/year) for 1188000,0000000J/29307600J/kg standard coal.

5. The returned slag of the previous furnace can be recycled due to the change of the formula and the feeding time of the fourth ingredient, the returned slag can carry out slagging reaction, and on one hand, the activated slag is produced, and on the other hand, a small amount of valuable metal in the slag is further extracted.

The foregoing is merely an example of the present invention and common general knowledge in the art of designing and/or characterizing particular aspects and/or features is not described in any greater detail herein. It should be noted that, for those skilled in the art, without departing from the technical solution of the present invention, several variations and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
