Continuous microsphere gas phase carbon coating production process

The invention relates to the technical field of lithium/sodium battery negative electrode material production, in particular to a continuous microsphere gas phase carbon coating production process which comprises the following steps: S1, heating stable gas to 900-960 DEG C; s2, feeding the stable gas into a Venturi mixer, and adding the microspheres, so that the stable gas heats the microspheres; s3, the microspheres are subjected to gas-phase carbon coating through carbon source gas through a coating generator and a coating tower, and the thickness of a coating layer is larger than 4 nm; and S4, after the gas-solid mixture from the coating tower passes through a heat exchanger and a water cooler, the temperature is reduced to 150-200 DEG C, the gas-solid mixture enters a bag filter to be subjected to gas-solid separation, gas is conveyed to a gas-gas separation system through a fan, and the solid enters a product tank through an airtight valve to be further cooled and then is packaged in a packaging system.
