In order to investigate the performances of commercial wave plate mist eliminators, measurment on separation efficiency and re-entrinment velocity were carried out. Experimental collecting efficiencies, as a fucntion of droplet size and gas velocity are carried out by the use of a Malvern Particle Sizer apparatus. Separation efficiency increases with gas velocity, but a sharp decrease occurs when the velocity is greater than a critical value (the re-entrinment velocity). Experimental investigations show that re-entrinment velocity depends on liquid flow rate, liquid surface tension and the geometry of the separator (the number of bends, the width of each channel and the bending angle between successive blades).

Abstract
In order to investigate the performances of commercial wave plate mist eliminators, measurment on separation efficiency and re-entrinment velocity were carried out. Experimental collecting efficiencies, as a fucntion of droplet size and gas velocity are carried out by the use of a Malvern Particle Sizer apparatus. Separation efficiency increases with gas velocity, but a sharp decrease occurs when the velocity is greater than a critical value (the re-entrinment velocity). Experimental investigations show that re-entrinment velocity depends on liquid flow rate, liquid surface tension and the geometry of the separator (the number of bends, the width of each channel and the bending angle between successive blades).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
