METHOD AND NOZZLE FOR MIXING MEDIUMS OF DIFFERENT VISCOSITY A multi-stage, especially a two-stage mixing of two media of different viscosity, and a respective mixing nozzle provided therefor. The first medium of higher viscosity is divided into two or more partial streams. The first partial stream is passed through an injector, in which the second medium of lower viscosity is mixed in, in particular tangentially. In an adjoining mixing chamber, the second partial stream of the first medium is admixed into the flowing mixture of the first partial stream and the second medium of lower viscosity and envelops the same, preferably in an opposite or counter-twist to the flowing twist of the first mixture of the first partial stream and second medium. This is especially suitable for bleaching of cellulose with oxygen. |
