Air purification device

The invention relates to an air purification device, comprising at least one air purification module. The module comprises a framework, at least one layer of an array formed of wire electrodes, and atleast one plate electrode. According to the invention, a traditional plate-type blocking medium structure is changed; the stability and safety of discharge are realized, gas resistance is reduced, tight combination of a catalyst and plasma is realized, one-stage coupling effect is realized, the coupling effect of low-temperature plasma and catalysis is improved, the utilization rate of energy isimproved, degradation efficiency and mineralization rate can be improved due to efficient catalytic performance, and O3 is reduced; and a gas flow direction and an electric field direction are the same, so the problem that a traditional wire plate type discharge reactor is difficult to amplify due to limitation of a discharge gap is solved. The device is simple in structural design, easy for modular assembly and industrial
