Abstract:A new type of cyclone technology called the circumfluent cyclone, which contains an inner cylinder, has been developed. This paper studies experimentally its separation efficiency and pressure distribution, while comparing its characteristics with the conventional cyclone. The results show that: i) the collection efficiency of the CFC is higher by 8% than that of a conventional cyclone (Dill-type) in the gas inlet velocity range of 12-26 m/s: ii) the pressure drop within conventional cyclone (Dill-type) increases rapidly with the increasing of gas inlet velocity, whereas the pressure drop within the CFC increases slowly in relation to the increasing gas inlet velocity and the pressure drop within the CFC is only one half or one third of that of the conventional cyclone; and iii) the distribution data of pressure drop and dust concentration in the CFC are in agreement with the theoretical description. Thus, it is suggested that the CFC has more separation efficiency, there is less pressure drop, more stable fluid flow, and less variation of performance with scale than is to be found in a conventional cyclone.
