摘要

为了进一步提高水力喷射空气旋流器（WSA）的传质效率以及认识射旋流体系的气液传质机理，对WSA中的射流流型进行了系统的观察研究，绘制出了不同进口气速下射流流型图。以CO2-NaOH化学吸收体系测定了相应射流流型下的有效比相界面积a。结果表明，在低射流流速（≤4.42 m·s-1）下，液相射流随着进口气速增大，主要存在稳态射流、变形旋线射流、破碎旋线射流、雾化旋线射流、贴壁雾化旋线射流5种流型；在高射流流速（≥6.19 m·s-1）下，射流主要出现稳态射流、破碎旋线射流以及雾化旋线射流3种流型。a值与流型有关，雾化旋线射流下的a值大于其他流型下的对应值。低流速下的贴壁雾化，不利于气液两相充分接触，对应a值较小。a值与射流流速有一定关系，随着射流速度的增大而略有增大，且随着射流流速增大至8.84 m·s-1以上，增大的幅度变大。

Abstract

Water-sparged aerocyclone (WSA) is high efficiency gas-liquid mass transfer equipment

which takes the advantage of coupling effect of gas cyclone and liquid jet fields.In order to investigate the mechanism of jet-cyclone system of WSA and improve its mass transfer performance

jet flow pattern and its transformation was investigated by direct observation. Effective gas-liquid interfacial area per unit volume (a) of the WSA was also determined by chemical reaction method with CO2-NaOH solution system. The results show that jet flow pattern is mainly affected by jet velocity and air inlet velocity. There exists five jet flow patterns in the WSA

i.e.

steady state jet

deformed spiral jet

broken spiral jet

atomized spiral jet and total atomized spiral jet at jet velocity less than 4.42 m·s-1. At the jet velocity higher than 6.19 m·s-1 there exists only three jet flow patterns

i.e. deformed spiral jet

broken spiral jet and atomized spiral jet. The value of a is related to jet flow pattern

higher in atomized spiral jet than in other jets

and increases with liquid jet velocity because of the intense gas-liquid interaction in the WSA.
