The utility model discloses a pinene photocatalysis oxidation device which adopts the structure that medium-voltage sodium lamps are arranged in the center of a reaction vessel; a quartz cold trap is arranged between the medium-voltage sodium lamps and the reaction vessel; a chilled water outlet and a chilled water inlet are formed in the cold trap; an oxygen input, a gas outlet, a feed opening, a discharge opening, a cooling jacket, a jacket cooling water inlet and a jacket cooling water outlet are formed in the reaction vessel; the jacket cooling water inlet and the jacket cooling water outlet are formed in the cooling jacket; a tetrafluoro coated rotor and a magnetic stirring apparatus matched with the tetrafluoro coated rotor are arranged at the bottom of the reaction vessel; the oxygen input comprises three pipes which are arranged on the same plane surface at 120 degrees' intervals; the oxygen inlet is formed in a position being twice higher as the rotor, perpendicular to a central shaft, and connected onto the reaction vessel. The pinene photocatalysis oxidation device has the advantages that the problem that the pinene and a solvent cannot dissolve each other is solved; the reaction time is short; the product yield is high; impurities are less; the production is safe, environmentally friendly, and low in energy consumption; the superiority is more obvious than a device adopting the conventional peroxy acetic acid oxidation method; technical problems of large scale industrialized production of pinocarveol, myrtenol and other products are solved; the application prospect is wide.
