Abstract: The present invention relates to a device for liquid degassing by means of swirling or centrifugal force coupled with a pressure gradient. This device comprises a cavity. The cavity is furnished with an inlet for liquid-gas mixture, a gas outlet and a liquid outlet. The gas outlet is inserted into the cavity through the top end of the cavity and positioned around 0.1-3 times the maximum diameter of the cavity from the top of the cavity. Specifically, an overflow pipe with the diameter gradually increasing from the bottom to the top was used as the gas outlet. The overflow pipe is further furnished with a bell mouth at the bottom part.
