Okay, imagine you're playing in a sandbox and you accidentally get sand all over your clothes. You wouldn't want to keep wearing those dirty clothes, right? You'd probably want to wash them in the laundry to get all the sand out.
Well, sometimes factories or power plants create pollution that's like the sand on your clothes. This pollution is made up of tiny things called particles that can be harmful for people and the environment if they're not taken out. That's where wet scrubbers come in.
Wet scrubbers are kind of like giant washing machines for the air coming out of factories. They use water (just like how your laundry machine uses water) and something called a scrubbing liquid to clean the pollution out of the air before it's released into the environment.
As the dirty air enters the scrubber, the scrubbing liquid sprays onto the particles and sticks to them, kind of like glue. The air and liquid moves around and around, and the particles get heavier and heavier as more and more scrubbing liquid sticks to them. Finally, the now heavy and wet particles fall to the bottom of the scrubber and can be collected and taken away.
So, just like how your clothes get clean after a wash with water and detergent, the pollution in the air can be cleaned with water and scrubbing liquid in wet scrubbers. This helps to keep people and the environment healthy and safe.
