Abstract
The invention discloses an energy-saving and environment-friendly method for recycling waste acid storage batteries. The energy-saving and environment-friendly method comprises the following specific steps of: cutting waste lead-acid storage batteries by utilizing a cutting machine, and then putting the cut waste lead-acid storage batteries into a breaking hammer for breaking; adding water into broken materials, and removing floating plastic particles; adding into a stirring device for stirring and simultaneously adding reducing agents such as ferric sulfate and dilute sulphuric acid; filtering reacted materials, and recycling a filtrate; then adding a desulfurizing agent such as sodium carbonate, and carrying out solid-liquid separation after the reaction is finished; generating sodium sulfate for recycling after carrying out crystallization and impurity removal treatment on the filtrate; and putting dried solid metal carbonate in a smelting furnace, adding a reducing agent (iron powder) and a reducing agent (carbon), reducing lead carbonate in the solid metal carbonate into lead liquid, introducing generated carbon dioxide gas into sodium hydroxide liquid, and generating sodium carbonate for recycling. The energy-saving and environment-friendly method disclosed by the invention has the advantages that the energy consumption is reduced, the waste and the discharging of waste liquid are also reduced, and regeneration of pollution is avoided.
Description
Technical field
The present invention relates to the lead acid accumulator field, be specifically related to a kind of energy-conserving and environment-protective spent acid storage battery recovery and treatment method.
Background technology
Internal storage battery mainly is made up of copper connecting head, plumbous connector, screen and lead plaster, and wherein, copper connecting head, plumbous connector, screen all are to make with high-purity copper and lead, and lead plaster then is to make with lead-containing alloy, contains alloying components such as antimony, calcium, bismuth in the lead plaster.The reviver that four kinds of constituent mixtures are obtained by high-temperature mixing is a kind of lead bullion, this regeneration lead bullion contains antimony, calcium, bismuth, the multiple composition of copper, can not be directly used in the processing of accumulator plate, behind the necessary high temperature heating and melting, adding alkaline oxidiser again utilizes chemical method to carry out refining removal of impurities processing, after obtaining original text purity regeneration lead bullion, could be used for the processing of accumulator plate.At present, as if the lead acid accumulator that generally adopts reclaims, the disposal means do not play basic effect for preventing of polluting of lead metal.The lead metal contaminated environment causes children blood lead, and the situation of infringement people ' s health happens occasionally.China most secondary lead smelting producer is for the waste lead acid battery smelting technology, and its production scale, technical matters and process equipment are lower to the regeneration rate of lead, environmental pollution is more serious.
Summary of the invention
The objective of the invention is to overcome that work efficiency is low in the existing spent acid storage battery removal process, cost recovery is high, energy waste is serious, easily produce deficiencies such as environmental pollution, a kind of energy-conserving and environment-protective spent acid storage battery recovery and treatment method is provided, the work efficiency height, cost recovery is low, save the energy, do not produce environmental pollution.
The technical problem that the present invention solves is achieved through the following technical solutions: a kind of energy-conserving and environment-protective spent acid storage battery recovery and treatment method, and concrete steps are as follows:
1, utilize cutting machine that waste and old lead acid accumulator is cut, the shape that is cut into small pieces, and then put into quartering hammer and carry out fragmentation;
2, will add water in the material after the fragmentation, make the plastic grain thing floating, remove floating plastic grain;
3, add agitating device and stir, add reducing agent ferric sulfate, dilute sulfuric acid simultaneously, under 65 ℃ of conditions, stirred reduction reaction 1-2 hour;
4, reacted material is filtered, obtain solid metal sulfide, filtrate cycle is used;
5, discharge filtrate, in solid metal sulfide, add water, stir with agitating device;
6, add desulfurizing agent sodium carbonate again, under 65 ℃ of conditions desulphurization reaction 2-3 hour, reaction was carried out Separation of Solid and Liquid after finishing, and obtains the solid carbonic acid metal object; Filtrate is handled the back through the crystallization decontamination and is generated the sodium sulphate recycling;
7, will wash, push in the solid carbonic acid metal object filter-press and 50 ℃ drying, obtain dry solid carbonic acid metal object;
8, drop into the solid carbonic acid metal object of drying in the smelting furnace and add reducing agent iron powder and reducing agent charcoal, reductase 12-3 hour under 1000 ℃ of conditions, ceruse in the solid carbonic acid metal object is reduced to plumbous liquid, plumbous liquid after the melting is delivered to refining furnace obtains lead bullion, the carbon dioxide that produces feeds in the caustic lye of soda, and it is recycling to generate sodium carbonate.
Adopt the beneficial effect of technique scheme to be: the inventive method environmental protection, take pollution-free measure comprehensively.The rate of recovery is higher, and overall recovery plumbous in the inventive method has reached more than 95%, and the rate of recovery of plastics has reached more than 90%, and the comprehensive utilization of resources rate reaches 95%.The present invention is with the filtrate and the gas that produce in the removal process, and the process recycling is carried out recycling, has reduced energy resource consumption, and has reduced the discharging of waste and waste liquid, has avoided producing again polluting.
Embodiment
Below in conjunction with specific embodiment the present invention is further explained explanation.
