水力喷射空气旋流器（WSA）是一种利用液体射流在气体旋流场中雾化强化气液传质的新型传质设备，可广泛用于废水、废气处理等环境工程过程中。为了优化水力喷射空气旋流器的分离空间结构，本文通过废水氨氮吹脱实验对柱锥结合形WSA和柱形WSA分别进行了气液传质性能研究。研究结果表明，分离空间结构对水力喷射空气旋流器的气液传质性能存在影响。在相同工作条件下，与柱形WSA相比，柱锥结合形WSA具有更好的气液传质性能和略高的气相压降，后者吹脱氨的体积传质系数提高了约8%，主要原因在于柱锥结合形WSA内部具有更好的射旋流耦合雾化作用和离心超重力强化传质的综合效果，使得两相比传质面积增大，传质效率增高。研究结果可为设计传质性能良好的WSA提供设计依据。

Water-sparged aerocyclone(WSA)is a new type of gas-liquid mass transfer equipment with a coupling field of liquid jet with gas cyclone,which could be widely used in wastewater treatment process. To further optimize the structure design of the water-sparged aerocyclone , this paper comparatively studied the mass transfer performance in two kinds of WSA with a conical and a cylindrical separation space configuration,by air stripping of ammonia from wastewater. The results indicated that the separation space configuration of a water-sparged aerocyclone had effects on its mass transfer performances. Under the same conditions,the WSA with a conical structure exhibited better mass transfer performances and higher gas pressure drop,and the mass transfer coefficient of ammonia stripping in the WSA with a conical structure was increased by 8%,which was probably caused by a comprehensive effects of the better jet atomization and centrifugal high gee intensification in its coupling field,forming larger interfacial area between gas and liquid phase. The results could be used as a guide for the design of WSA with good mass transfer performance.
