An electrostatic precipitator helps to clean the air. Just like how you clean your room, we clean the air by getting rid of things that make it dirty like tiny particles of smoke and dust.
So, imagine your room is dirty and your mom asks you to clean it. You would pick up all the toys, books and arrange them neatly, right? But how do you clean the air?
An electrostatic precipitator is like a special machine that does this job. It is made up of metal plates that have a charge running through them. When the dirty air flows through these plates, the tiny particles like dust and smoke stick to them because of the charge.
Now, you know when you rub a balloon against your t-shirt, and your hair sticks to it? That's static electricity! The metal plates in the electrostatic precipitator work like that. They have a charge that helps to attract the dirty particles from the air.
Once the dirty particles stick to the plates, they are collected and removed from the machine, and the cleaned air is sent back into the atmosphere. The electrostatic precipitator makes sure that the air we breathe is as clean as possible!
So, in simple words, an electrostatic precipitator is like a magic machine that cleans the air by using static electricity!
