Description
Technical Field
The utility model relates to a graphitization system, and belongs to the technical field of graphitization production in the carbon industry. In particular to a circulating graphitization system for producing lithium battery cathode materials.
Background
Along with the increasing severity of global climate change, the global call for environmental protection is becoming higher, and people begin to search for more environment-friendly and sustainable energy systems, mainly including electric automobiles and battery energy storage systems. Batteries are used as electric vehicles and battery energy storage systems, and generally mainly comprise a positive electrode material, a negative electrode material, a diaphragm, electrolyte and the like. With the rapid development of energy storage of the electric automobile and the battery at present, the current market needs cathode materials which are estimated to be 150 ten thousand tons each year, and the market scale is rapidly expanded. At present, the graphitization production of the cathode material is basically carried out by adopting a fixed graphitization furnace, namely, each fixed station is required to complete all the working procedures of the whole graphitization production, including heating, cooling, material taking, charging and the like. From the energy consumption perspective, because the graphitization furnaces are heated by adopting direct current, the power of the transformer needs to be sent to the two ends of each graphitization furnace, and the existing graphitization furnaces are fixed, so that one transformer needs to be connected to 15 furnaces, on one hand, the investment cost of copper and aluminum bars of the furnaces is high, on the other hand, the loss of electric energy on the copper and aluminum bars is very high due to the longer copper and aluminum bars, and the electric energy waste is expected to be about 5% of the electric charge of the whole graphitization production. From the aspect of environmental protection, since the graphite furnaces are fixed, each furnace needs to be provided with equipment such as material taking and charging, and the like, the graphite furnaces are inconvenient to seal the graphite furnace area in the heating process, and the problems of sulfide and organic volatile matters in the heating process of the graphite furnaces cannot be solved. In addition, the charging and taking area of the graphite furnace is very large, the whole factory building is basically occupied, no corresponding independent charging and taking area exists, and the problem of dust pollution cannot be solved because the dust pollution is particularly large during charging and taking. From the perspective of intellectualization, since each fixed furnace corresponds to all the production processes, the heating, charging and taking equipment and the like are large in quantity, and space cross operation exists, so that the intellectualization is basically unrealistic and the investment is huge.
Aiming at the defects of a fixed graphitizing system, china patent (issued publication No. CN 107188165B) discloses a large-scale movable graphitizing system which comprises a graphitizing furnace, a transformer and a water tank, wherein the graphitizing furnace is floated in the water tank through a buoyancy tank arranged at the bottom and is pulled to move in the water tank through a winch, and the transformer is arranged at the outer edge of the water tank; the water tank is provided with a charging station area, a discharging station area, a power transmission station area, a first cooling station area, a second cooling station area and a furnace building maintenance station area. However, although the large movable graphitization system realizes the movement of the graphitization furnace among different fixed stations, the system supports and transports the graphitization furnace by utilizing the buoyancy tank, and has the problems of low movement efficiency, high cost and high safety risk.
In view of the defects of the existing graphitization production system, the utility model provides a graphitization system to overcome the defects of the prior art.
