Abstract
The device comprises a closed chamber (1) equipped with an inlet pipe (3) for the aerated liquid, an outlet pipe (4) for the deaerated liquid, and an air evacuation pipe (5); and a rotor having a shaft extending into the chamber. The shaft carries means (7) for centrifugation of the liquid and means (8,9,10) for intensive agitation of the centrifuged liquid. The device works according to the following process: continuously, the liquid is introduced into the closed chamber and it is vigorously centrifuged there in with the aid of mechanical means (7) and simultaneously subjected to intensive agitation with the aid of second mechanical means (8,9,10). The released air gathers freely at the center of the chamber whence it is evacuated, as the deaereated liquid is evacuated through the outlet pipe.
Claims29
A process for degasifying a gasified liquid, comprising the steps:
- introducing said liquid into a chamber;
- providing centrifugal means inside said chamber for rotating said liquid about an axis;
- rotating said liquid using said centrifugal means about said axis in said chamber to subject said liquid to centrifugal force to release gas from said liquid, said liquid moving to a region radially away from said axis, said released gas moving toward said axis;
- providing agitating means in said region for agitating liquid, said agitating means being radially substantially outward of said centrifugations means;
- simultaneously with said rotating, agitating said liquid in said region with said agitating means to aid in further release of gas;
- providing a duct having one open end positioned at said rotational axis and the other end leading externally of said chamber;
- removing said released gas from said chamber through said duct.
Device for degasifying a gasified liquid, said liquid containing suspended solids, comprising:
- a chamber having an inlet for input of said gasified liquid, an outlet opening for degasified liquid, and an outlet for gas discharge;
- a rotor within said chamber, said rotor including a shaft for rotation about an axis, means connected to said shaft for centrifugation of liquid delivered through said inlet, and means connected to said shaft for agitating said liquid during centrifugation;
- a static perforated envelope within said chamber, said envelope being substantially coextensive with said centrifugation means and enclosing said rotor, said envelope dividing said chamber into a first zone and a second zone, said means for centrifugation and said means for agitation being in said first zone, said first zone communicating with said liquid inlet and said gas outlet, said second zone being substantially coextensive with said first zone and communicating with said liquid outlet opening, said second zone being radially outwardly displaced from said axis and said first zone.
Device for degasifying a gasified liquid, said liquid containing suspended solids, comprising:

- a rotor within said chamber, said rotor including a shaft for rotation about an axis, means connected to said shaft for centrifugation of liquid delivered through said inlet, and means connected to said shaft for agitating said liquid during centrifugation;
- a static perforated envelope within said chamber, said envelope dividing said chamber into a first zone and a second zone, said first zone enclosing said means for centrifugation and said means for agitation and communicating with said liquid inlet and said gas outlet, said second zone communicating with said liquid outlet opening, said second zone being radially outwardly displaced from said axis and said first zone.
