Research on Characteristics of Spiral Flow Generator in a Horizontal Liquid-Solid Circulation Fluidized Bed

Abstract:

An experimental study is carried out to investigate the structure parameters and pressure drop characteristics of a spiral flow generator in a horizontal liquid-solid circulation fluidized bed. The CCD image measurement and data processing system was used to study the particles distribution at different angles covering 10°, 15°, 20°and 25°normal to the axial ﬂow direction. Increasing the vane angle resulted in lower particles non-uniform results. The vane angle has important influence on generation of the spiral flow in horizontal circulation fluidized bed. The pressure loss with spiral flow generator is higher than that without spiral flow generator. The average increase in pressure losses was about 110% in comparison with that for the pipe without spiral flow generator. The vane angle of 15° represented the minimum pressure drop values.
