The distribution of the liquid film in a new-type cyclone separator was investigated by two parallel-wire conductance probes which were designed based on variation conductance.It was found that the liquid film on the section surrounding the entrance was distributed asymmetrically with a spiral path.The maximal value of steady liquid film appeared at about 160°.The distribution area of liquid film increased with inlet gas velocity

which was good for separation because of larger centrifugal power.But the thickness of the liquid film decreased

which was bad for lowering abrasion.The change of the inlet angle had a significant influence on the liquid film surrounding the inlet.A larger inlet angle would decrease the distribution area of the liquid film around the inlet.In addition

the size of vent-pipe had no significant influence on the distribution of liquid film

and the thickness of the liquid film increased with the vent-pipe diameter.
