Optimization of the new generation multichannel cyclone cleaning efficiency

Abstract

Cyclone Dust Separators are devices often used to filter solid particles from flue gas. Such cyclones are supposed to filter as much particulate matter from the gaseous stream as possible. At the same time, they should only introduce minimal pressure loss to the system. Hence, collection efficiency has to be maximized and pressure loss minimized. Both the collection efficiency and pressure loss are heavily influenced by cyclone geometry. In this paper, we optimize inner geometrical construction of multichannel cyclone to up cleaning efficiency parameter. This study shows how geometry involves cleaning efficiency. At air flow rates from 12 m/s to 18 m/s after researches the optimal cleaning efficiency achieved in the three level cyclone at 16 m/s average air flow rate in cyclone channels, when the treated air is polluted with 20 μm size granite particles and flow distribution ratio is 75/25. For low density particles (wood ash) for the 20 μm diameter top efficiency established in 6-channel cyclone at the 16 m/s air flow rate in the channels and flow distribution ratio 75/25.
