<p>A centrifugal vacuum degassing device and method are provided. The device comprises a shell (100) defining an inner cavity. The shell (100) has a liquid inlet (200) for feeding the liquid to be degassed into the inner cavity and a gas evacuation outlet (400) for evacuating gas from the inner cavity. The gas evacuation outlet (400) is connected with a vacuum evacuation device. A rotary wheel device (104) is arranged between the liquid inlet (200) and the gas evacuation outlet (400) within the inner cavity and can rotate about a rotating axis (155). The rotary wheel device (104) is provided with a couple of gas sidewall (106) and liquid sidewall (108) facing each other along the direction of the rotating axis (155), between which a gas-liquid passage connecting the liquid inlet (200) with the gas evacuation outlet (400) is defined. A plurality of extending pieces (111, 112) in opposite directions are extended from the gas sidewall (106) and/or liquid sidewall (108) and used to stir the gas and liquid within the gas-liquid passage in the rotary wheel device (104) to generate a rotary motion. The gas and liquid are separated from each other under the centrifugal effect. The separated gas reaches the gas evacuation outlet (400), while the degassed liquid flows to a liquid collecting trough (107) under the effect of the centrifugal force. The liquid collecting trough (107) is located at the inner surface of the shell (100) in the vicinity of the rotary wheel device (104) and connected with a liquid outlet (300) for discharging the liquid.</p> |
