What function does the collecting section of an electrostatic precipitator serve?

The collecting section of an electrostatic precipitator is primarily responsible for trapping and removing particles from the airflow. In this component of the system, particles that have been previously ionized in the ionization stage acquire an electric charge. The collecting section contains plates with an opposite charge that effectively attract these charged particles, causing them to adhere to the plates, thereby removing them from the air stream.

This process enhances air quality by reducing particulate matter, making the electrostatic precipitator an important component in various industrial applications where controlling emissions is necessary for environmental and health reasons. The ability to efficiently trap and remove very small particles is a key advantage of this technology.
