Study of Gas-solid-solid Three-phase Flow in Non-Powered Separator

The non-powered separator is one of the key equipment in dry sand production line, which responsible for separation coarse and fine materials. In this paper, based on turbulence Standard Model, air powder three-phase fluid model simplified to gas-solid-solid flow, 3D was built. process simulated by using Fluent software. It found that larger volume control valve blade angle is, more removed, can be adjusted range 15° 60° according actual needs industrial production.
