APPARATUS FOR LIQUID DEGASSING USING COUPLING OF SWIRLING FLOW OR CENTRIFUGAL FIELD AND PRESSURE GRADIENT FIELD

摘要

An apparatus for liquid degassing using coupling of a swirling flow or centrifugal field and a pressure gradient field comprises a cavity. Liquid-gas inlets (1-1, 1-2), a gas phase outlet and a liquid phase outlet (4) are arranged on the cavity. The gas phase outlet is inserted into the cavity from a center of an upper surface of the cavity. An insertion depth is 0.1-3 times a maximum diameter of the cavity. The gas phase outlet is achieved through an overflow pipe with a radius gradually increasing from bottom to up. A horn mouth (9-1) is further arranged at a tail end of the overflow pipe, forming an inverted-cone-shaped gas phase outlet structure that goes deep into the swirling flow apparatus cavity.
