摘要：
A new type of desulfurization absorber with double-contact-flow has many advantages on operation and maintenance. The flow regimes of gas-liquid two-phase flow and their transition in this kind of absorber are investigated and analyzed. Using the direct observation method, the probability density function (PDF) method, and the bed expand method, the macroscopical flow characteristic is recorded. And the pressure fluctuation of different flow patterns is measured. With the increase of liquid gas ratio, four flow regimes are detected and identified, which are liquid-column flow, liquid-screen flow, surging flow, and quasi-bubbling flow. The flow regime map of liquid-gas ratio (L/G) versus gas Reynolds number (Re-g) is presented. And hydro-mechanical parameters of flow patterns transition are given.
