It sucks in smoke Smoke is made up of mostly solid substances dispersed in a gas. The electrostatic smoke precipitator generates static electricity, this then gives the solid particles passing through them a negative charge. The particles then pass through to two positively charged conducting plates and, due to their negative charge, they are attracted to the plates where they collect and form a layer.
Thomasnet, Globalspec and Wisegeek all provide online information on electrostatic precipitators. Wikipedia also contains an extensive article on them.
cleaning the dirty particles in the air
There are different dust collection systems available. The most efficient dust collection systems include electrostatic precipitators. Electrostatic precipitators are highly efficient and highly costed.

In process plant environment, SO3 gas is mixed into flue gas from combustion to make the ashes charged up before flowing through electrostatic precipitators. The electrostatic precipitators will then trap the ashes, making cleaner process emission possible.

Electrostatic precipitators can capture carbon particles by using an electric field to charge the particles. The charged particles are then attracted to collection plates with opposite charges, where they adhere and accumulate. This process effectively removes carbon from the air, making electrostatic precipitators an efficient method for carbon capture and air purification.
Power stations found electric gas cleaning in electrostatic presipitators an efficient way to recover valuable products carried out of the stacks from the operations of the furnace.
Lightning is a Natural phenomenon which shows Static electricity. Xerox machine works on the principles of static electricity , Electrostatic precipitators control solid pollution from a smoke works on this electrostatic principles , Some spray coatings and powder coatings are also working on the same principles
Electrostatic precipitators can only remove particulate or droplets from exhaust gases. This includes, but is not limited to: dust, fumes, mists, fog, powder, smoke, hair, paint over spray, ash. Gases cannot be removed by this method.
