2) electrostatic precipitator
3)fabric filter
4) wet scrubber

Answer 1

i think (2) electrostatic precipitator....

Answer 2

Answer:

Electrostatic precipitator is the air pollution control devices is suitable for removing finest dust

Option B

Explanation:

Air pollution is also caused in industries by a very fine particle whose diameter is less than 4 micron. These are usually inhaled and it causes a strange occupational disease known as pneumoconiosis. Electrostatic precipitator helps in attraction and repulsion of micro-particles based on the electrical gradient.

They are precious downwards and prevented from reaching the air. Usually, the chimneys are fitted with the electrostatic precipitator where an electrical field is set up from outside. This prevents exposure to such particles.
