Gas-liquid cylindrical cyclone (GLCC) is a perpendicular pipe with a tilted tangential inlet and gas and liquid outlets and the separation of gas from liquid may be realized by it through cyclone centrifugal force.As compared with the traditional container-like separators,the GLCC has many advantages as well-knitted structure,a little weight and economizing-on investment,etc.,thus being a novel device instead of the traditional separators.On the basis of analyzing two-phase swirling flow,the mechanism models including an inlet separating model,a vortex model and the trajectory models of bubbles and droplets were established for predicting gas-liquid separation behaviour.According to the mechanism models,the technical criteria and procedure of technological design are proposed in the paper.Through example calculation it is shown that the mechanism models are reasonable and suitable for engineering design.
