Efficient molten aluminum degassing process method

The invention discloses an efficient molten aluminum degassing process method in the field of molten aluminum processing. The method comprises the following steps that (1), molten aluminum is introduced, specifically, a first aluminum water source prepared by smelting aluminum ingots and a second aluminum water source prepared by smelting aluminum wastes in a combustion furnace are introduced intoa degassing cavity of a hearth; (2), inert gas is prepared, specifically, nitrogen, helium and carbon dioxide in channels of three gas supply assemblies are introduced into a mixed gas chamber for mixing; and (3), degassing is carried out, specifically, the molten aluminum is heated to 830-845 DEG C firstly, mixed gas in the mixed gas chamber are respectively introduced into the gas channels of arotating shaft I, a rotating shaft II and a rotating shaft III in three paths, inlets of the gas channels of the rotating shaft I, the rotating shaft II and the rotating shaft III are respectively incommunication with the mix
