NOVELTY - The utility model claims a smoke gas processing device of experimental atmosphere furnace, comprising a cylinder body; a filter assembly and an exhaust assembly; the cylinder body is provided with a flue gas inlet pipe; the cylinder body is provided with a first limiting block below and a second limiting block above; the filter assembly is set in the cylinder body above the flue gas inlet pipe; the filter assembly comprises a first filter structure and a second filter structure. The utility model effectively purifies the flue gas generated by the experimental atmosphere furnace, avoids the flue gas directly discharged to the external environment, causes great harm to the experimental staff and environment; the graphene carbon block and the active carbon block for double purification treatment, ensures the clean flue gas treatment; and by setting the second stainless steel net set in the cylinder body, so as to conveniently change the active carbon block and the graphene carbon block.
