Design of scale graphite automatic purification device based on liquid surface discharge plasma technology

In view of the scale graphite purification in the process of process conditions and equipment complex, high cost, and environmental pollution, this paper through the basic principle of scale graphite purification and the characteristics of lowtemperature plasma, according to a new graphite purification technology, designs a graphite purification device with a simple structure, which is easy to operate. The purification process has no waste gas, waste liquid emissions, and no pollution to the environment, which conforms to the development of green environmental protection concept, solves the issues that traditional graphite purification method purification equipment cannot continuously operate, and has long purification cycle, high cost, and serious pollution. According to the graphite carbon content test of the purified products, it is known that the graphite purification device in this paper can purify the graphite with 92% carbon content to the graphite with a carbon content of more than 99%.
