Abstract
A device for mixing the components of a mass flow flowing through it, provides a particularly homogeneous mixture with any desired long-term stability, even if components which are generally immiscible or can only be mixed with very great difficulty are being mixed. The device has a body (8), which it is difficult for medium to flow around, arranged in a through-flow chamber (4), this body being arranged at least partially in a part of the through-flow chamber (4) which widens in the direction of flow, so that the cavitation action and mixing action of the supercavitation field generated by the body (8) which it is difficult for medium to flow around is significantly reinforced.
Claims26
Device (100) for mixing the components of a mass flow flowing through it, in which the components may in particular be in solid, liquid or gas form, by means of a hydrodynamic supercavitation field, in order to generate a mixture, in particular an emulsion or suspension, having a housing (1), which has an entry opening (2) for supplying at least part of the mass flow which is to be mixed and an exit opening (3), for removing the mass flow;
- the housing (1) having a through-flow chamber (4) with a body (8), which it is difficult for medium to flow around, arranged therein by means of a holder (6), and the body (8) which it is difficult for medium to flow around having at least two subregions (80;
- 10) which it is difficult for medium to flow around and which are each responsible for local constriction of the flow, characterized in that the through-flow chamber (4), at its start, has a through-flow chamber section (42) which narrows in the direction of flow, and in that the internal diameter of the through-flow chamber (4), following the narrowing through-flow chamber section (42), at least in the region which surrounds the body (8) which it is difficult for medium to flow around, increases in the direction of flow of the mass flow flowing through the through-flow chamber (4), wherein the body (8) which it is difficult for medium to flow around can be displaced along the direction of the center axis of the through-flow chamber (4), the subregions (80:
- 10), which it is difficult for medium to flow around, of the body (8) which it is difficult for medium to flow around are produced by means of a plurality of part-bodies (10) which it is difficult for medium to flow around, and at least one of the part-bodies (10) can be displaced, independently of all the others (10), along the direction of the center axis of the through-flow chamber (4).
