The using method of the utility model high-efficiency vertical oil separator device is: the cold-producing medium of high pressure superheater and refrigeration oil gas phase mixture enter downstream chamber in the cylinder by air inlet pipe, and move as rotary centrifugal force along the radially tangential direction of cylinder inner wall uniformly with constant flow velocity, most of refrigeration oil is split into cylinder under action of centrifugal force inwall again under the effect of self gravitation with the form of liquid state toward current downflow, and by in a plurality of pilot holes inflow collection chambers on the oil seal plate peripheral plane, unsegregated cold-producing medium of part and refrigeration oil gas phase mixture carry out secondary separation through the essence filter body of middle multilayer separating screen, gas up goes out from escape pipe by the airflow hole at essence filter body center, freezing oil catch down in the pilot hole of oil seal plate periphery flows into the collection chamber of bottom, is realized separating fully outside screen cloth.Liquid refrigeration oil enters compressor by oil return opening, and vapor phase refrigerant enters the next stage condenser device by the overdraught chamber in the cylinder by escape pipe.

The beneficial effects of the utility model are, this high-efficiency vertical oil separator device has utilized rotary centrifugal force and the know-why that smart filter separates, and cold-producing medium and refrigeration oil gas phase mixture is carried out secondary separate fully, makes the Oil-gas Separation process more abundant, improve efficiency, realized stablizing oil return.Overall structure is simple, and volume reduces, and making and easy for installation has improved 10-15% than existing oil eliminator oil gas separation, has reduced energy consumption.
