A study on design and test performance of glass bottle cyclones
Abstract:
This study was an experimental study that designed and tested performance of axial entry glass bottle cyclones. The first experimental step was the selection ofan appropriate shape of glass bottle for construction of glass bottle cyclones. The second experimental step was the study ofthe influences of outlet duct diameters and inlet vane angles on cyclone performances. All types of glass bottle cyclones were tested with grinding dust at airflow rate of 12 cfm and particle concentration between 330-400 mg/m3. The stack sampling method was used to measure the particle concentration at the inlet and outlet areas. The collected data were calculated according to the separation efficiencies of cyclones.
The results showed that the average separation efficiencies of glass bottle cyclones, which were constructed from Sauce, Beer and Nectar bottles, were 99.81%, 98.31% and 97.31% respectively. The Sauce bottle cyclones showed significant differences of separation efficiency between inlet vane angles 20°, 25°and 30° (p<0.001). However, there were no significant differences of separation efficiency between De,0.42D and De,0.5Dcyclones (p>0.067). The results also indicated that the variations of outlet duct diameters and inlet vane angles influenced pressure drop. The study results revealed that the Sauce bottle cyclones could be used to control grinding dust.
