摘要
Abstract
Using RSM and DPM models, the gas flow field and droplets movement trajectory in axial flow gas-liquid cyclone separator were numerically calculated. The results show that, there exists strong short circuit flow beneath the gas exhaust pipe in the cyclone, and the droplets escape via the short circuit flow is the most important cause for the reducing separating capability of the cyclone. In order to get improvement, four gas exhaust pipes with different inlet structures were designed and numerically calculated. The separating capability experiments of the cyclones with above four structures separately were carried out respectively. Results show that the above short circuit flow and pressure drop are greatly affected by the inlet structure of the gas exhaustpipe, and the 4th structure designed is an ideal configuration, for the short circuit flow beneath it is weakest and its pressure drop is least. It was found that the numerical calculation results agree well with the experimental results, which validates the reliability of the numerical calculation; and in the meantime, a novel inlet structure for gas exhaust pipe in gas-liquid cyclone separator was developed.关键词
