1. Ionizing Electrodes: These electrodes, also known as corona electrodes, are responsible for ionizing the particles in the gas stream. They generate a corona discharge, which charges the particles, preparing them for collection. 2. Collection Electrodes: The collection electrodes, also called plates or tubes, are where the charged particles are collected. They have an opposite charge to the ionizing electrodes, creating an electrostatic field that attracts the charged particles. 3. Rapping System: The rapping system is used to remove the collected particles from the collection electrodes. It consists of mechanical devices or electromagnetic hammers that vibrate the electrodes, causing the dust cake to dislodge and fall into a hopper. 4. Hopper: The hopper is a container located at the bottom of the electrostatic precipitator. It collects the dust and other collected particles that have fallen from the collection electrodes. The hopper can be equipped with devices such as screw conveyors or rotary valves for efficient removal of the collected material. 5. Power Supply: The power supply provides the necessary voltage and current for the electrostatic precipitator to function. It ensures that the ionizing electrodes are charged and the collection electrodes have the appropriate voltage to attract the charged particles.
