The invention belongs to the technical field of air disinfection and purification and relates to a
metal strap-plate structure reactor comprising positive electrodes, negative electrodes and a housing, wherein each positive
electrode is positioned between the two neighboring negative electrodes, and the housing is provided with an air inlet and an air outlet. The
metal strap-plate structure reactor is characterized in that the positive electrodes are arranged in the same plane by a plurality of oxidization-resistance
metal straps and arranged in parallel by equal distance to form an
assembly, and the negative electrodes are made of aluminum plates or stainless
steel plates; and both ends of each positive
electrode are respectively fixed on a microdischarge-preventing conducting rail, and both ends of the microdischarge-preventing conducting rail are fixed with the housing through an insulating connector. The metal strap-plate structure reactor effectively prevents the microdischarge phenomena of the positive electrodes, prolongs the service life of the metal straps, enhances the concentration of
plasma generated by the reactor, improves the air disinfecting and purifying efficiency and has energy saving. The aluminum plate surfaces of the negative electrodes are coated with TiO2 so that the reactor has the effect of yielding twice the result with half the effort. The reactor is a
core component of a non-thermal
plasma air disinfecting purifier and is a regenerated product of a sawtooth-shaped or needle-point-shaped reactor with nonuniform
corona discharge.
