Experimental Study on Effect of Inlet Condition on Corrugated Plate Dryer

The effects of inlet condition including droplet size,inlet moisture content and inlet airflow speed on corrugated plate dryer’s performance were studied in a visualized experiment system.A laser particle sizer was used to measure water particle size distribution.The results show that: the separation efficiency increases with the increasing of droplets size and inlet moisture content,and increases with the increasing of inlet velocity firstly,then decreases after reaching the peak; the critical inlet speed resulting re-entrainment decreases with the inlet moisture content increasing; the pressure drop of dryer increases with the inlet air speed quadratically.
