As exemplified in the drawing to the side, the flow of air to be treated is introduced tangentially into the cyclone where the particles present in it are accelerated and pushed to describe a circular trajectory. They, due to the centrifugal force, separate themselves from the gaseous stream heading towards the wall of the cyclone. Then solid particles are dragged by the gravity force at the bottom of the filter where they are removed. In this way, the air treated comes out from the top of the filter.
The separation efficiency of the system depends on:
- the size of the particles (granulometric distribution);
- the specific weight of the particles;
- the speed of the airflow;
- the geometric dimensions of the cyclone.
Due to the peculiarity of the operating system, is very important during the design phase to define the scope and the flow rate and the specific temperature of use.
