The anode and cathode rapping hammers of the electrostatic precipitator are the core components for removing dust accumulation on the electrodes. Their functions and maintenance points are as follows:
Core Functions and Technical Features
Dust Removal Mechanism
Anode Rapping Hammer: Strikes the anode plate (collecting electrode) to dislodge adhered dust into the hopper, preventing dust buildup from affecting conductivity;
Cathode Rapping Hammer: Clears dust accumulation on the cathode wire (corona electrode) to ensure discharge efficiency.
Synergistic Effect: Periodic impact of the hammer head on the anvil generates mechanical vibration to break up compacted dust.

Structural Design
Component Type? ?Typical Structure? ?Applicable Scenarios
Anode Rapping Hammer? F-shaped bent arm design, hammer head thickness ≥10mm (thickened slotted type) Areas with high dust load on anode plates
Cathode Rapping Hammer? T-shaped or lightweight straight arm structure, matched with porcelain rotating shaft (withstand voltage ≥35kV) Cathode wire suspension system
Connectors? Clamps and connection clips secure the hammer arm, precision casting process prevents detachment Force transmission between rapping shaft and hammer head
