Question

Cyclone collector is used for minimizing
(a)Radioactive pollution
(b)Air pollution
(c)Noise pollution
(d)Water pollution

Answer 1

Hint: The cyclone collector uses the concept of centrifugal force that causes the undesired particulates to migrate to the outside of the main chamber and under the effect of gravity those particles fall to the bottom of the cyclone collector.

Complete step-by-step answer:
The cyclone collector is used for removing the industrial dust from air or processed gases and thus helps in minimizing the air pollution. The process of removal of the particulates can be understood simply as – the gas is spun rapidly, under the effect of centrifugal force the heavier particulates get collected outside, and from there, they are removed. The detailed principle of operation of the cyclone collector is as below –
The main driving force for the separation of particulate matter from the carrier gas is the centrifugal force and the difference in specific gravity between the carrier gas molecules and the particulate matter to be separated also becomes an advantage. The air containing particulate matter is forced into a long chamber of the cyclone collector along the tangential axis of the chamber. Due to this, a helical flow pattern of air is created inside the chamber and thus the centrifugal force is generated. This force causes the particulate matter to migrate outside the chamber and there they fall under the effect of gravity and in this way the air in the main chamber becomes free from the particulate matter. A cyclone collector has been shown below –

Note: The cyclone collector is used by the industrial plant where a large volume of air is generated that contains particulate matters harmful to the health of humans and other animals. The particulates are too small and they easily pass to the lungs through the respiratory passage and cause many problems. This is a type of air pollution and it is minimized with the help of cyclone collectors.
