摘要

阐述了y形分支管内气固两相的流动分布特性。对密度为1340 kg/m3和2510kg/m3,平均粒径为2mm的小米和微玻璃珠进行了气力输送实验,采用水平y形支管,其中一根支管为不变(保持15°),另一根支管为可变(角度分别为5°、10°、15°、20°、25°、30°)。流动分布特性由流动在可变分支中的固体质量与固体总质量之比表示。

Flow distribution property of Y-Shaped branch pipe in gas-solid two-phase flow
The flow distribution property of gas-solid two-phase in Y-Shaped branch pipe was expatiated. The pneumatic conveying experiments for millet and micro-glass bead with density 1340 kg/m3 and 2510kg/m3, average particle diameter 2mm were carried out at horizontal Y-shaped branch pipe which were designed with one branch being unchanged (keeping 15°) and the other being changeable (the angle values are 5°, 10°, 15°, 20°, 25°, 30° respectively ). The flow distribution property was expressed by the ratio of the solid mass flowing in the changeable branch vs. the total mass of solid.
