Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of dust collecting device, especially the technical field of import pre-charging device. BACKGROUND

[0002] As one of the main equipment of industrial flue gas purification, the electric dust collector is widely used in the industrial fields of electric power, metallurgy, building materials and the like due to its high total dust removal efficiency, low body resistance, large amount of flue gas treatment, high temperature resistance, strong corrosion resistance and low operation and maintenance cost. The electric dust collector is a device for separating suspended particles in gas by using electric power. Although there are various types and structures of electric dust collectors in practical application, they are all based on the same working principle. The dust removal process of the electric dust collector can be divided into four stages, i.e. ionization of gas, charging of suspended particles, migration and settlement of charged particles, and dust cleaning. However, in actual industrial application, the collection efficiency of the electric dust collector for particle dust is often not ideal. In the face of more stringent ultra-low emission standards, the electric dust collector needs to further improve the collection efficiency for particle dust in the electric power industry or non-electric industry.
