Abstract

In a multi-chamber centrifuge for gassing or degassing of liquids which has a floor 7, a corresponding lid 3 placed at a certain distance, with gaps to permit the passage of gas in the floor 7 and lid 3, with a liquid pipe connection in the lid 3 and two sets of coaxially mutually fitting cylinders, the set (=rotor) with the rotating cylinders rises from the floor 7, while the other set (=stator) descends from the lid 3 and is static. The cylinders of one set each penetrate the gaps between the cylinders of the other set, and each set of cylinders leaves a radial gap by reaching just short of the opposite base (either the floor 7 or the lid 3). At least some of the cylinders of the rotating set can be made at least partially of a woven material which can be fashioned like a sieve. On the static cylinders 4, vibration generators 19 and/or heating devices 13 may be installed (FIG. 1).
