Electrostatic Dust Collectors Used In Iron And Steel Plants Discharge Electrodes

Electrostatic precipitator anode plate usually uses stainless steel (such as 201, 202, 304, 304L, 316L, etc.) as the main material. These stainless steel materials have the characteristics of high temperature resistance and corrosion resistance, and can meet the needs of different working conditions. Electrostatic precipitator anode plate usually has a certain geometric shape (such as C type, Z type, etc.) to increase the dust removal area and improve the dust removal efficiency. The surface is smooth and smooth, which is conducive to the deposition and removal of dust particles.The working principle of electrostatic precipitator anode plate is based on the action of high voltage electric field. When a high-voltage electric field is formed between the cathode line of the anode plate connected to the HVDC power supply and the grounded anode plate, corona discharge occurs in the cathode and the gas is ionized. The negatively charged gas ions move towards the anode plate under the action of electric field force, and collide with the dust particles and charge them negatively. The charged dust particles also move towards the anode plate under the action of electric field force, and release negative charge and deposit on the anode plate after reaching the anode plate. After a period of accumulation, the dust layer on the anode plate will gradually thicken and reach a certain thickness. At this time, the dust layer on the anode plate needs to be removed by shaking or other means to maintain the normal operation of the dust collector.
