The invention discloses an evaluation device for deoxidant performance, and relates to the technical field of petroleum. The evaluation device comprises a nitrogen cylinder, a first liquid storage tank, a second liquid storage tank and a reaction tank, wherein the nitrogen cylinder is communicated with the first liquid storage tank through a first valve, the first liquid storage tank is communicated with the reaction tank through a second valve, the second liquid storage tank is communicated with the reaction tank through a third valve, and the reaction tank is communicated with the first liquid storage tank through a fourth valve. The evaluation device provided by the invention is capable of effectively avoiding a problem that a follow-up experiment cannot be performed because of oxygen exposure of a water sample in a sampling process, in the sampling process, a nitrogen gas in the nitrogen cylinder is directly controlled to enter the first liquid storage tank through the first valve,so that the dissolved ox
