Cyclonic separation

Cyclonic separation is a method of removing particulates from an air gas or liquid stream without the use of filters through vortex separation When removing particulate matter from liquid a hydrocyclone is used while from gas a gas cyclone is used Rotational effects and gravity are used to separate mixtures of solids and fluids The method can also be used to separate fine droplets of...
