The invention provides an air disinfection harmful gas removal purifier. High-energy particle bombardment is adopted to be combined with multiple adsorption, formaldehyde, benzene and other poisonousand harmful gas as well as virus, bacteria and other microorganisms in air are removed, high-energy particles are generated by adopting a plate-shaped electrode high-voltage high-frequency electric discharge structure, and the good flowing property is kept. The air disinfection harmful gas removal purifier guides the flowing direction and the flow velocity of the air properly, the flowing direction of the air deflects at the high-energy particle bombardment position, on the one hand, sufficient reaction is facilitated, on the other hand, sediment is not prone to accumulating, the flow velocityof the air is controlled properly, and optimization of the purifying and collecting effects is achieved. All parts of the air disinfection harmful gas removal purifier are relatively single, no curved structure exists, and designing, producing and assembling are easy.
