Description

technical field

[0001] The invention relates to a device and a method for promoting the interaction of different types of particles, in particular to a device and a method for promoting the interaction of particles by using electrode charging. Background technique

[0002] In many industrial production processes, a large amount of harmful particulate matter is produced and discharged into the atmosphere. Among these particles, the most harmful ones are submicron particles. Since submicron particles are easily inhaled by the human body and enriched in toxic compounds, governments around the world have formulated and continuously updated stringent legal standards to control the emission of particulate matter (PM10) with a diameter of less than ten microns. At the same time, environmental problems such as photochemical smog and high atmospheric opacity are directly caused by particulate matter, especially ultrafine particulate matter. In view of the fact that the smaller the p...
