新型逆喷式洗涤喷嘴气液两相传质特性研究
The Gas-Liquid Two-Phase Mass Transfer Characteristics of a New Reverse Jet Washing Nozzle
摘要
Abstract
According to the existing reverse jet washing technologies, this paper proposed a new washing nozzle with three liquid inlets for wet flue gas cleaning in industry. In a cold model experimental setup, the characteristics of hydrodynamic and gas-liquid two-phase mass transfer of the scrubber using the proposed nozzle were investigated by using the dissolved oxygen method. The variations of the flow patterns, the mass transfer efficiency and the pressure drop with the operating parameters in the scrubber were discussed. Moreover, the new nozzle characteristics were compared with the DynaWave nozzle recognized as one of the excellent conventional reverse jet nozzles. It was shown that the proposed nozzle has a better mass transfer efficiency , and a wider operating range, etc. What’s more, when the mass flow ratio of the liquid and gas is greater than 1.2, and the axial and tangential liquid mass flow ratio is in the range of 0.4~2.2, a Bubble Flow pattern will appear, and the mass transfer is the best.关键词
