Experimental research on the dynamics of airflow parameters in a six-channel cyclone-separator

• Standard and upgraded structures of curvilinear semi-rings were analyzed.
• The arrangement of semi-rings and also spaces among them are changed.
• Size of the cross-section used for the filtration of dirty air changes.
• Cleaning efficiency was equal to 97.3%, at 10 g/m3 PM up to 50 μm.
• Cleaning efficiency was equal to 74.1%, at 10 g/m3 PM up to 20 μm.

The dynamics of airflow parameters were researched in a six-channel cyclone (separator with a tangential flow). The dependencies of dynamic pressures in cyclone's channels and of cleaning efficiency on an airflow inlet velocity were analyzed. Standard and upgraded semi-rings were used in the cyclone's internal structure. Changes in cleaning efficiency at different inlet concentrations of glass and technical salt particles were analyzed. Research results were obtained at inflow velocities of 10.9 m/s to 21.9 m/s. The highest cleaning efficiency was 97.3%.
