The structural property of the fluid-solid （gas） swirl-liquid separator for environmental protection and chemical industry is described. Their flow field structure is analyzed,, then the flow line and mobile phenomenon are observed. According to a series of experiment data, the velocity function of quasi-free-vortex in cylinders are calculated. Using the 2D axisymmetric cylindrical vortex model, this pressure distribution of quasi-free-vortex in cylinders are studied. By the principle of fluid-solid （gas） liquid swirl, the separation particle diameter and efficiency are discussed. Through experimental technique the fluid flow of the fluid-solid （gas） swirl-liquid separator are explaned. Finally, the examples of environmental projects are introduced, and the application prospects are discussed.
