The utility model relates to an oxidation reactor feed system of an alcohol ketone device. The oxidation reactor feed system of the alcohol ketone device comprises a feed pump, a heat exchanger, a mixer and a passivator feed pipe, wherein the outlet pipe of the feed pump is connected with the inlet tube pass of the heat exchange A; the outlet tube pass of the heat exchanger A is connected with the inlet tube pass of the heat exchanger B; the outlet tube pass of the heat exchanger B is connected with the inlet shell pass of the heat exchanger C; the outlet shell pass of the heat exchanger C is connected with the inlet shell pass of the heat exchanger D; the outlet shell pass of the heat exchanger D is connected with the inlet shell pass of the heat exchanger E; the outlet shell pass of the heat exchanger E is connected with the inlet tube pass of a steam heater; the outlet tube pass of the steam heater is connected with the inlet of the mixer; the outlet of the passivator feed pipe connected with a passivator storage tank is connected with the inlet of the mixer; and the outlet of the mixer is connected with the inlet of an oxidation reactor. By using the feed system, the amount of the passivator entering the oxidation reactor is not reduced, the pipeline and the heat exchanger tube bundle are prevented from being blocked by the passivator, and the heat resistance of the heat exchanger is not increased.
