Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0044] There are a large number of high-energy electrons, positive ions and active groups in the low-temperature plasma. When the high-energy electrons touch the bacterial cell wall, tiny through holes will be left on the surface of the bacterial cell wall, destroying the structure of the bacterial cell wall, and the active groups in the air will combine with the bacterial cell wall. It can prod...

Abstract

The invention discloses an air purification device for disinfecting pathogenic microorganism aerosol based on plasma, which includes a plasma discharge device and a strong electric field collection device connected thereto; wherein, the plasma discharge device includes a rotating field corona discharge device and an air dispersion device Plasma jet device. At least one pair of corona discharge discs is arranged in the rotating field corona discharge device; the corona discharge discs include several first corona discharge needles and several layers of conductive fiber filaments wound between adjacent first corona discharge needles. The air-dispersed plasma jet device includes at least one pair of jet arrays. The rotating field corona discharge device in the present invention produces long-life active particles that can effectively disinfect bacterial aerosols, and combines corona discharge needles with conductive fiber filaments to enhance discharge and improve charging efficiency. The air-dispersed plasma jet device produces short-lived and highly active particles and groups that can effectively disinfect virus aerosols.

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...
