Abstract
The present invention relates to an apparatus for carrying out chemical and physical processes, wherein flowable substances are mixed together, comprising a vertical, cylindrical vessel with inlets and outlets, as well as a central shaft and radial agitator blades arranged on the said central shaft and extending close to the wall. In this context, viewed in the peripheral direction, the agitator blades are curved and are combined in pairs of agitator elements one above the other to form groups, the blades of one element of the group being curved in a radially concave manner and the blades of the other element being curved in a radially convex manner.
Claims15
Apparatus for performing chemical and physical processes, wherein flowable substances are mixed together, comprising
- a cylindrical vessel with inlets and outlets,
- a central shaft and
- radial agitator blades arranged on the shaft, extending close to the wall, such that a gap between the blades and the wall is adapted to a size of particles passing through the reactor, characterized by the following features:
- a) the agitator blades are designed in a curved manner when viewed in the peripheral direction and
- b) are combined in pairs of agitator elements, positioned one above the other, to form groups,
- c) the blades of one element of the group being curved in a radially concave manner and the blades of the other element being curved in a radially convex manner and
- d) the blades are tapered towards their free ends.
Process for preparing polymers in a tubular reactor, the reaction components being moved through the reactor in an axial direction and in the course thereof being conveyed alternatingly towards and away from the reactor axis by pairs of agitator blades, curved in opposite directions, combined to form groups one above the other, substantially normal to the reactor axis, thereby intensely mixing the reaction components, the blades being tapered towards their free ends.
