In the modern society, which is brought into the electronic age, the more and more the varieties and the larger the quantity of electromechanical products and electronic devices in the modern society, the functions of human locomotory organs, sensory organs and even thought organs are greatly expanded and extended by various electromechanical products, and in these products/devices, chemical power supplies-batteries which are convenient to carry and move are widely used. The common batteries in the common appliances and vehicles mainly comprise primary batteries represented by zinc-manganese batteries and secondary batteries with increasingly diversified varieties, such as nickel-metal hydride batteries, lithium ion batteries, lithium batteries, nickel-cadmium batteries and the like. The material types in the batteries comprise various elements such as mercury, cadmium, lead, zinc, manganese, cobalt, nickel, copper, silver and the like, the compounds comprise inorganic and organic acids, bases, salts, polymer films and the like, the mixture and the composition comprise inorganic and organic compounds and coexistence compounds of the inorganic and organic compounds, and the physical forms comprise powder, films, sheets, frameworks, colloids, gases and the like. In short, in order to increase the efficiency of batteries and various application functions, battery contents having complicated shapes have been developed, and the variety of shapes of battery contents has been increasingly diversified with the development of people.
These diverse materials present in the battery tend to increase the difficulty of disposal once the battery is discarded due to failure. If the treatment is improper, serious environmental pollution is caused and resources are wasted. For example, lead, mercury, cadmium and even precious metals in the water form toxic and harmful substances or solutions which cause secondary pollution to the environment, and organic and inorganic substances in the water are all those which are difficult to degrade in the natural environment and are easy to cause serious damage to the environment.
On the other hand, if the various substances in the waste batteries can be effectively recycled, the waste can become a new resource source, thereby reducing the burden and pollution of the environment and increasing the quantity and variety of available resources.
However, at present, except that the waste lead-acid batteries are easy to be collected independently and recycled by a pyrometallurgical method due to special external dimensions and use occasions, the zinc-silver batteries are easy to be recycled independently due to the precious metals, and the like, for a large number of other waste common batteries which are recycled in a mixed manner, due to the fact that electrode materials are increasingly numerous, electrode structure differences and external dimensions are various, previous grade sorting is difficult to refine, effective sorting means and equipment are not available at home and abroad, subsequent physicochemical deep processing is difficult to perform, the efficiency of subsequent processing of the waste common batteries is influenced, industrial processing of a large number of waste common batteries is difficult to develop and continue, scale benefits and industrial advantages are not mentioned, and attention and support of the society, the public and governments are not obtained.
Chinese patent application No. 200510033231.3 discloses a method for recycling mixed waste batteries and a special roasting furnace thereof, wherein the method comprises the following steps: the method comprises the following steps of (1) unpacking and discharging treatment of waste batteries; (2) crushing the battery and washing away the electrolyte in the battery; (3) Washing the crushed materials with water, ball-milling, and roasting to separate organic matters, mercury, cadmium and zinc; (4) Separating the battery shell, the iron and copper current collectors by a screening method; (5) The undersize products are leached by alkali to remove aluminum and zinc, then are acid-dissolved after being roasted, and then rare earth elements, impurities, nickel and cobalt elements in the acid-dissolved solution are separated by using a chemical precipitation and solvent extraction method. The method is economic and reasonable in process and good in effect, and the mixed waste batteries do not need to be classified and sorted in advance. The special roasting furnace is formed by sequentially connecting an air blower, a roasting furnace body, a cooler and a flue gas filter, and is easy to prepare and good in treatment effect. However, the method uses the principle process of pyrometallurgical and hydrometallurgical processes for reference, and adopts mixed treatment which is basically not separated for a large amount of mixed and recycled waste common batteries, but the treatment method and equipment which are not distinguished are difficult to adapt to the development trend of increasingly innovative electrode materials and structures, and the treatment effect and the secondary pollution residue are difficult to further improve.
