Electrostatic Precipitator
What are Electrostatic Precipitators?
How Does It or What Makes It Work?
The Process
Diagram A
This diagram shows the main components of the electrostatic precipitator. You can see the gas (polluted going into the machine, clean leaving it), the energy supply at the top, the metal collection plates, and the hoppers. Note this diagram doesn't show the ionizing wires.
Diagram B
This diagram shows the process of the polluted gas being cleaned, or filtered, as it goes through the electrostatic precipitator. It is a close up version of the inside of a precipitator, therefore you can see the ionizing wires.
In Real Life
This is what an electrostatic precipitator looks like from the outside. If you ever see one of these as you drive through an industrial area of town, you'll know what it is.
