Nowadays, the recycling of used lithium batteries in China has become a complete system of metal resources recycling. The cobalt, lithium, copper and plastic in used batteries are very important resources for recycling, so the recycling of used batteries will cause significant improvement in environmental performance and can also achieve good economic benefits. What needs to be used is Lithium battery recycling and separation equipment，The following small A Rong will provide a detailed introduction to the lithium battery recycling technology process and the entire process of lithium battery recycling and processing equipment being.
Lithium battery is mainly composed of: positive electrode, negative electrode, shell, electrolyte, diaphragm and other metals. Among them, the positive electrode is coated with lithium cobaltate powder evenly on both sides of the aluminum foil collector through the bonding action PVDF. The structure of positive and negative electrodes is very similar. The negative electrode is composed of: carbonic acid bonded on both sides of the copper foil collector fluid thus. The recycling of used lithium batteries is mainly the recycling of cobalt and lithium, which contain valuable cathode precious metals. Lithium battery negative sheet in which copper is used is a very important production raw material, the weight ratio can be as high as about 35%, carbon powder adhered to it. It can be used as an additive for rubber, plastic, etc. So the lithium battery negative piece for effective separation, from the child to achieve the waste battery recycling resources, to eliminate the pollution and harm to the environment of electronic waste, the more commonly used lithium battery recycling resources: pyrometallurgy, wet metallurgy, mechanical physical method three. Mechanical physics does not require the use of any chemical reagents, and low energy consumption, so it is more environmentally friendly and more efficient method.
The waste charged lithium batteries are first transported to the oxygen-free feeder for de-oxygenation and crushing, after crushing, the materials need to be discharged with closed air to isolate the oxygen, and then the oxygen-free high temperature is quickly painted, and the materials after passing will be sent into the sorting system, plastic film, magnetic materials, aluminum, copper, plastic, etc. in lithium batteries are sorted out. The remaining positive and negative pieces are then put into the friction system of high speed operation for depowdering, and the materials after depowdering are then passed through screening, airflow and dust collection. At this time, the positive and negative powder, plastic, copper and aluminum metal are separated. The electrically charged positive and negative powder is sent to the anaerobic decomposition Xiyong for anaerobic decomposition, and the generated gas and sorting waste gas are combusted together, and then the heat from the combustion is used to provide a heat source in the cracking furnace, and then the decomposed waste gas is supplemented with oxygen and organic gas. The incinerated exhaust gas is then cooled, sprayed, filtered, separated and adsorbed by activated carbon to meet the emission standards.
