Method for injecting a first fluid into a second fluid and an apparatus for carrying out the method

Abstract

In injection of steam, gas or liquid into a fluid product in an injection apparatus having a substantially disc-shaped rotor (5) and having a central product inlet (10) and a peripheral product outlet (11), the injection is carried out in a limited zone (13) above the disc-shaped rotor (5) at a distance from both said inlet (10) and said outlet (11), the fluid product being also exposed to a radial displacement effect and a tangential dispersion effect. The fluid product may be a liquid with considerable variation of dry solids content and viscosity. The injection apparatus comprises at least one cylindrical wall (7, 8) projecting upwards from the disc-shaped rotor (5), which wall projects between coaxial cylindrical walls (14, 15) projecting downwards from an overlying stator cover (9). The coaxial cylindrical walls (7, 8, 14, 15) on the rotor (5) and the stator cover (9) are formed with substantially axis-parallel sharp-edged slots (19), and feed passages (16) are connected to the stator cover (9) for injection into a space (13) positioned between the coaxial cylindrical walls (14, 15) on the stator cover (9) and constituting an injection chamber.
