Abstract

The invention belongs to the technical field of low-temperature plasma application, and relates to an electric discharging device of a rotation electrode. The device comprises an impeller, a rotation electrode, a fixed electrode, and an electric motor, wherein the rotation electrode is arranged between the electric motor and the fixed electrode, and is fixedly arranged on the impeller or a shaft of the electric motor. The electric motor drives the impeller and the rotation electrode to move. High voltage is applied between the rotation electrode and the fixed electrode, and corona discharging is generated between the two electrodes. Since the electric motor drives the rotation electrode to move, corona rotates with the movement to draw a large-volume plasma area. Plasma is uniformly dispersed in a whole airflow channel between the two electrodes. Therefore, the electric discharging device can be applied to an air purifier and allows no dead corner to be left during purification. Moreover, the rotation electrode can greatly reduce the ozone yield, and prolongs the service life of asymmetric electrodes.

Description

technical field [0001] The invention relates to the field of low-temperature plasma technology, in particular to a discharge device for a rotating electrode. Background technique [0002] In recent years, the problem of environmental degradation has become increasingly prominent, and the application of low-temperature plasma technology in environmental protection has also attracted more and more attention. Plasma organic waste gas purification, plasma wastewater purification, plasma automobile exhaust purification and plasma formaldehyde removal, TVOC and PM2.5 and other related technologies and product development have received unprecedented attention. [0003] PM2.5 from fossil fuel combustion and formaldehyde and TVOC pollution from interior decoration have increasingly become important factors that seriously affect people's quality of life. Taking home decoration pollution as an example, the existence of volatile organic gases headed by formaldehyde in the indoor air se...
