摘要： The present disclosure discloses a plasma purification device for purifying catering oil fume and a method for purifying catering oil fume, relating to the technical field of atmospheric pollution control. The plasma purification device successively includes in a flow direction of airflow an inlet, a rotary discharge module configured to negatively charge oil fume particulate matter with a particle size between 2 μm and 50 μm in the catering oil fume; an electrostatic adsorption module configured to capture negatively charged oil fume particulate matter; a back corona catalytic module configured to treat VOCs in the catering oil fume; and an outlet. The rotary discharge module includes a central rod arranged parallel to the flow direction of airflow and a plurality of barbed corona electrodes arranged around the central rod.
