What function do rappers serve in an electrostatic precipitator?

Rappers play a crucial role in the operation of an electrostatic precipitator by helping to remove dust and other particulate matter from the system. The primary function of an electrostatic precipitator is to collect these particles from flue gases in industrial applications, and rappers contribute to this process by periodically shaking or vibrating the collection electrodes.

As dust and particulates accumulate on the collection plates, their removal is necessary to maintain the efficiency of the electrostatic precipitator. Rapping helps dislodge this buildup, allowing the particles to fall into hoppers for subsequent removal. This action is vital for maintaining optimal performance and ensuring that the precipitator can continue to effectively cleanse the exhaust gases of pollutants.

While airflow is important for the operation of the system and could be influenced by various factors, the specific task of rappers is directly associated with the mechanism of dust removal rather than enhancing airflow, insulation, or temperature regulation.
