Description
A comprehensive recycling method of nickel-cadmium waste batteries relates to a technology for harmless treatment and recycling of nickel-cadmium and nickel-hydrogen storage waste batteries.
As is known to all, the waste batteries are discarded without being treated, so that the environment is polluted, and particularly, toxic heavy metal cadmium contained in the nickel-cadmium batteries is easy to enrich in plants, so that the human health is easily injured by food through water, soil and the like. The method adopts a simple vacuum metallurgy method for treatment, and has low energy consumption and operation cost and small secondary pollution, but the method does not recycle the useful substances in the waste batteries, thereby causing resource waste.
Therefore, people adopt two treatment methods of pyrometallurgy and hydrometallurgy to recycle nickel-cadmium waste batteries. Wherein the pyrometallurgical treatment method of the catalyst chemical company of Guanxi Japan mainly utilizes the characteristic of high vapor pressure of cadmium and oxides thereof and nickel separation. And (3) after the coating layer on the surface of the battery is stripped, oxidizing roasting is carried out at 900-1200 ℃, so that the nickel is separated into nickel cinder and cadmium oxide concentrated solution, the nickel cinder is used as a steel smelting raw material, and the cadmium oxide concentrated solution is leached and purified to be prepared into various cadmium salts or metals. Various crushed nickel cadmium cells were treated with a rotary furnace at 1260 ℃ by INMETCO, usa, and the collected gas was sprayed with water. The residue in the water, which contains a large amount of cadmium as well as lead and zinc, is sent to a cadmium refining plant for purification. The iron-nickel residue in the furnace is sent into an electric arc furnace to be melted to prepare iron-nickel alloy, and the non-toxic residue can be sold as building aggregate. The Tokyo resource company in the hydrometallurgical processing method peels off and crushes the battery coating layer, and leaches the battery coating layer and sludge slag together with sulfuric acid to remove impurities such as iron and the like. Then hydrogen sulfide is blown into the nickel-cadmium solution to form cadmium sulfide precipitate for separation, and sodium carbonate is added into the nickel-cadmium solution from which cadmium is removed to form nickel carbonate for sale. The waste nickel-cadmium battery hydrometallurgical recovery treatment of Dutch research institute is to crush and screen waste nickel-cadmium batteries, the coarse particles mainly comprise iron shells, plastics and paper, the coarse particles are divided into iron and non-iron parts through magnetic separation, then the iron and non-iron parts are respectively cleaned by hydrochloric acid, iron fragments after the cadmium is removed are removed, and iron-nickel alloy is produced, while the non-iron fragments are disposed of dangerous objects due to the cadmium. Leaching the fine particles with acid solution, disposing the residue as hazardous waste, and extracting cadmium from the filtrate with solvent. The cadmium-containing extract is re-extracted with dilute hydrochloric acid to produce a cadmium chloride solution. Finally, the cadmium is recovered by an electrolytic method.
It can be seen from the above recovery method of nickel cadmium battery that in both methods, except for the high energy consumption caused by the high heating temperature required by pyrometallurgical treatment, cadmium has toxicity, and the generated cadmium-containing waste gas and waste water must be strictly treated, so both methods have the disadvantages of long flow, high investment and operating cost, easy generation of serious secondary pollution, and low comprehensive benefit.
The invention aims to provide a method for recycling and comprehensively utilizing nickel-cadmium and nickel-hydrogen storage waste batteries with less pollution and low energy consumption.
The invention is carried out by mixing various waste nickel-cadmium batteries together, and breaking the shell; the nickel-hydrogen storage battery is disassembled. Then, the battery is subjected to vacuum heating treatment for 2 hours at the temperature of 600-750 ℃ and under the condition of 20-30 mmHg, cadmium, plastics and the like are gasified and volatilized, and the gas is condensed to recover cadmium and then is subjected to activated carbon purification treatment to reach the standard and be discharged; then, in order to recover other metals in the waste battery, crushing the battery after vacuum heating treatment, and dissolving heavy metals such as nickel, iron and the like in the crushed battery by using nitric acid with the concentration of 10-50%, sulfuric acid with the concentration of 10-40%, or mixed acid of nitric acid with the concentration of 10% and hydrochloric acid with the concentration of 20% which is 1-6 times of the weight of the battery to form leachate; then filtering the leaching solution, wherein filter residues are a small amount of undissolved metals, and continuously adding the acid into the leaching solution for further digesting the metals; adding alkali and ferrous sulfate into the filtrate, and preparing ferrite by chemical precipitation. Finally, obtaining the ferrite product with wide application by centrifugation and drying. The centrifuged effluent is reused for dissolving the dilute acid configuration of the waste battery.
The chemical precipitation method adopted by the invention refers to an oxidation method and a neutralization method. The oxidation method is that ferrous sulfate is added into the filtrate of the leachate of the waste battery, and the weight of the filtrate is that the crushed waste battery and FeSO are added4·7H2And (3) neutralizing the O (W/W) at a ratio of 1: 2-6 with alkali until the pH value is 8-9 to generate a colloidal suspension containing the metal ion hydroxide precipitate, adjusting the pH value to 10.0-12.0, heating at 60-100 ℃ for 0.5-5.0 hours at a constant temperature, and uniformly blowing pure air for 20-90 minutes to oxidize the intermediate precipitate to generate ferrite. The ion reaction equation is as follows: in the formula M2+(M+) Is heavy metal ion Ni2+、Cd2+Etc. of the structural formula M2+Fe3+O4(M+ 1/2Fe5/2 3+O4). R is Na+、K+、NH4 +。
The reaction mechanism of the oxidation process is as follows: when the precipitated hydroxide generates soluble divalent metal hydroxy complex through ionization equilibrium, the divalent hydroxy complex reacts with oxygen to generate trivalent hydroxy complex, and then the divalent and trivalent metal hydroxy complexes react with each other to generate colloidal suspension in the form of solid solution, and under the condition of heating or heating oxygenation, the colloidal suspension is converted into the spinel-type ferrite which is difficult to dissolve.
The neutralization method comprises the steps of firstly adding ferrous sulfate into filtrate obtained by filtering the leachate, wherein the addition amount of the ferrous sulfate is waste battery amount and FeSO4·7H2Preparing ferrite preparation liquid by using O (W/W) in a ratio of 1: 2-6, adding strong base solution, adjusting the pH of the preparation liquid to 9.0-12.5, heating to 50-100 ℃, keeping the temperature for 0.5-3 hours, continuously stirring to obtain ferrite crystal precipitate, washing and filtering to obtain a wet ferrite product, and drying at 90 ℃ to obtain the ferrite product.
The invention has the following advantages:
1. because the vacuum heating treatment is adopted, airis prevented from participating in the operation, the generated flue gas amount is small, the purification is easy, the flue gas treatment scale is greatly reduced, and the secondary pollution is small. The centrifugal effluent is circulated, so that the standard discharge treatment cost is reduced, and the investment cost and the operation cost are reduced. The process of the invention has low energy consumption, and the power consumption for processing the nickel-cadmium battery is 1.0 KWh/kg.
2. Because the acid is adopted to dissolve and leach the metal in the waste battery after heating and crushing, the filtrate filtered by the leaching solution is used for preparing the ferrite by adopting a chemical precipitation method, and the integral recycling of the metal is really realized. The invention has high recovery rate of waste batteries, and almost all substances can be recycled as resources except organic matters such as plastics and the like.
3. The composite ferrite product prepared by the method can be used as a magnetic material, has stable performance and is not dissolved out under the condition that the pH value is 3-10.
