Example Embodiment

[0043]In order to make the objectives, technical solutions and advantages of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely intended to illustrate the invention and are not intended to limit the invention. Further, the technical features according to each of the various embodiments described below can be combined with each other as long as they do not constitute a collision between each other.

[0044]There is a large number of high-energy electrons, positive ions and active groups in low temperature plasma. When high energy electrons are contacted into bacterial cell walls, micro via holes are left in the surface of the bacterial cell wall, destroy bacterial cell wall structures, air in the active group and bacterial cell wall binding It can produce a concentration of superoxide and peroxide, these active su...

Abstract

The invention discloses an air purification device for killing pathogenic microorganism aerosol based on plasma. The air purification device comprises a plasma discharge device and a strong electric field collection device connected with the plasma discharge device, wherein the plasma discharge device comprises a rotating field corona discharge device and an air dispersion plasma jet device. At least one pair of corona discharge discs is arranged in the rotating field corona discharge device; the corona discharge disc comprises a plurality of first corona discharge needles and a plurality of layers of conductive fibers wound between the adjacent first corona discharge needles. The air dispersion plasma jet device comprises at least one pair of jet arrays. The rotating field corona discharge device generates long-life active particles which can effectively kill bacterial aerosol, the corona discharge needle and the conductive fiber are combined, discharge is enhanced, and the charge efficiency is improved. The air dispersion plasma jet device generates short-service-life high-activity particles and groups which can effectively kill virus aerosol.

Description

technical field [0001] The invention belongs to the technical field of air purification, and more particularly relates to an air purification device for disinfecting pathogenic microorganism aerosol based on plasma. Background technique [0002] Plasma is regarded as the fourth state of matter except solid, liquid, and gas. It is an electrically neutral substance composed of cations, neutral particles, free electrons and other particles with different properties. Plasma can be divided into two types according to its thermodynamic properties, one is high-temperature plasma, and the other is low-temperature plasma. Although the temperature of electrons is high during low-temperature plasma discharge, the temperature of heavy particles such as ions and neutral particles is low, and the whole system presents a low-temperature state close to room temperature. [0003] Bacteria and viruses in the air can be killed by using low-temperature plasma, but the efficiency of existing pl...
