Lead-acid accumulator and leaded regenerated resource development and utilization system
Technical field
The utility model belongs to the harmless processing and the resource regeneration technology of leaded refuse, is specifically related to a kind of nuisanceless processing of lead-acid accumulator and leaded refuse and regeneration system of resource regeneration of being used for.
Background technology
Lead resource is important nonferrous metal ore resource, and along with the increase day by day of demand in the world wide, the production of mineral products primary lead is faced with commercial mining reserves scarcity, the selecting and purchasing smelting process pollutes many-sided pressure such as serious relatively.For solving the critical shortage of first resource, simultaneously also from reducing raw material and smelting selection cost, and the consideration that increases that satisfies the demands sets out, and lead resource production has to more and more rely on plumbous secondary resource---the production of reviver, and wherein lead-acid accumulator has become the main source of reviver.On the other hand, along with the Chinese society rapid economy development, the increase day by day of automobile pollution, and the instrument of various use lead acid accumulators and equipment is increasing, the reasonable disposal of the lead acid accumulator of scrapping has become an important environmental protection subject under discussion.According to " national hazardous waste register ": lead-acid accumulator and leaded refuse belong to hazardous waste.It is disposed the unordered loss that will cause leaded acid solution and solid slag improperly, must cause the severe contamination of surrounding air, soil, the face of land and groundwater resources, and then threaten human body health by food chain.
Leaded refuse year of the whole nation producing scale will end to the end of the year 2008
Figure Y20092014445900031
Show that according to data the whole nation contains the scrap lead generation about more than 1,000,000 tons, and show a rising trend.Domestic Production of Secondary Lead is from aggregate level, the reviver number of the enterprise is many, small scale, energy consumption height, pollute heavy, technology falls behind, metal recovery and making a low multiple use.Traditional Production of Secondary Lead equipment adopts the smelting equipment that falls behind, and major part is not taked the environment protection treating measure, and environmental pollution is serious.How implementing scrap lead material specification handles on the spot in the scope of a given area, reduce energy resource consumption and process and pollute, take the lead in carrying out lead resource recycling in this area, is that current society has major issue to be solved.
From adhering to the theory of sustainable development and recycling economy, in conjunction with the existing resource regeneration encouragement policy of country, the scrap lead that contains that scrap battery that is produced with replacing storage batterys such as automobile, electric motor cars and storage battery manufactory produce is the reviver raw material, by lead-acid accumulator and the environmental friendly regenerated technical matters of utilizing of leaded refuse, obtain the reviver resource; And by the preparation of alloy and then the reviver alloy product of acquisition specific standard, make reviver return lead resource consumption and use the field, be to realize that leaded refuse comprises the harmless processing of lead acid accumulator and the technical research emphasis of resource regeneration.
The utility model content
The utility model provides a kind of discharging, realization lead-acid accumulator and leaded refuse that can effectively reduce pollutant to handle to greatest extent, and can realize the lead-acid accumulator and the leaded regenerated resource development and utilization system of recycling of recyclable waste, this regeneration system produced pollution thing amount is low, waste water, gas, slag all can be realized minimized and realize qualified discharge, handle the low reviver resource that also can produce high added value of energy consumption, circulation is used for battery refresh and produces.
The technical scheme that the utility model mainly adopts is as follows:
