Problems solved by technology

[0010] In the prior art: the root cause that the positive electrode of the plasma reactor is selected as thin metal wire is easy to be blown-the micro-discharge effect has not been discovered, and its physical reason is not clear, so there is no solution to prevent it Technical solutions for micro-discharge effects
Most of the air disinfection and purification equipment manufacturers who are implementing the air disinfection and purification equipment with the serrated or pointed needle reactor structure as the positive electrode of the plasma reactor discharge have previously done plasma reactors with metal wires as the positive electrode; and now they are sterilized by air Plagued by the contradiction between the purification effect and the concentration of ozone and nitrogen oxides exceeding the standard

Abstract

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.

Description

Technical field: [0001] The invention belongs to the technical field of air disinfection and purification, and in particular relates to a metal strip-plate structure reactor. Background technique: [0002] The non-thermal plasma reactor used for the existing air disinfection purifier is composed of a positive electrode, a negative electrode plate, an insulating support and a shell. The structure of the positive electrode mainly includes wire, zigzag or pointed needle. [0003] When the indoor air is at normal temperature and pressure, the oxidation-resistant thin metal wire, jagged or needle-shaped structure is used as the positive electrode of the discharge, and the oxidation-resistant metal plate is used as the negative electrode. This kind of reactor with extremely asymmetric discharge electrodes is used as the discharge electrode. When corona discharge produces non-thermal plasma for air disinfection and purification, the corona discharge of thin metal wires is uniform ...
