Describe the principle, construction, working and uses of cyclone separator.

1 Answer

Answer :

Principle: Centrifugal force  

Construction- 

1) Cyclone separator is size separation device

2) It consists of a cylindrical vessel with a conical base.

3) The upper part of the vessel is fitted with a tangential inlet and a fluid outlet.

4) At the base it is fitted with solid outlet

Working: 

The suspension of a solid gas (Usually air) is introduced tangentially at a very high velocity so that rotary movement takes place within the vessel. The fluid is removed from a central outlet at the top. The rotator flow within the cyclone separator causes the practices to be acted on by centrifugal force. The solid are thrown out to the walls. There after it falls to the conical base and discharge through the solid outlet.
