Production device and method of graphite carbon material

The invention relates to the technical field of carbon preparation, in particular to a production device and method of a graphite carbon material. Comprising a roasting furnace and a purification assembly, the purification assembly comprises a filter channel, a guide pipe, a one-way valve and a purification box, an alkaline solution is contained in the purification box, the roasting furnace is used for roasting raw materials to prepare carbon materials, waste gas generated during roasting is discharged into the filter channel, carbon particles in the waste gas are filtered out through the filter channel, and then the waste gas is guided into the guide pipe through the filter channel; the exhaust gas is guided into the purification box through the guide pipe to react with a solution, so that harmful substances in the exhaust gas are removed, the solution in the purification box is prevented from flowing into the guide pipe through the arrangement of the one-way valve, and the exhaust gas is filtered and purifi
