Description

Technical Field

[0001] This utility model relates to the technical field of anode plates, and in particular to the technical field of irregularly shaped anode plates. Background Technology

[0002] Electrostatic precipitators (ESPs) are one of the most widely used gas dust removal methods. When dust-laden gas passes through a high-voltage electric field, it is electrically separated. Dust particles combine with negative ions, becoming negatively charged, and then tend to discharge and deposit on the anode surface. The anode plate is the core component of the ESP. A high-voltage electric field is formed between the cathode wire connected to the high-voltage DC power supply and the grounded anode plate. Due to corona discharge at the cathode, the gas is ionized. The negatively charged gas ions move towards the anode plate under the influence of the electric field. During this movement, they collide with dust particles, causing the dust particles to become negatively charged. These charged dust particles also move towards the anode under the influence of the electric field. Upon reaching the anode, they release their negative charge and are deposited on the anode plate. The purified gas is then discharged from the dust collector. However, when the anode plate of the ESP is vibrated, a large amount of dust adhering to the anode plate falls into the ash hopper. Simultaneously, some finer dust particles are easily carried into the ESP by the flue gas flow, causing a significant increase in dust concentration during anode plate vibration, which fails to meet emission requirements.
