Abstract
A device for mixing the components of a mass flow flowing through the same provides a particularly homogenous mixture which remains stable for any length of time, even when the components concerned are generally not miscible or are very difficult to mix. The device has a body (8) which is located in a throughflow chamber (4) and is difficult to flow around. This body is situated at least partially in a part of the throughflow chamber (4) that expands in the direction of the flow, so that the cavitation effect and the mixing effect of the supercavitation field produced by the body (8) that is hard to flow around are considerably amplified.
Claims29
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).
The device (100) as claimed in one of the preceding claims, characterized in that the through-flow chamber (4) is at least partially rotationally symmetrical, its center axis being the axis of symmetry, and
- the body (8) which it is difficult for medium to flow around is arranged in such a way that its center axis coincides with the center axis of the through-flow chamber (4).
The device (100) as claimed in one of the preceding claims, characterized in that the body (8) which it is difficult for medium to flow around at least partially comprises an elastic, nonmetallic material.
The device (100) as claimed in one of the preceding claims, characterized in that
- the body (8) which it is difficult for medium to flow around has a hollow space (83) which passes all the way through it and has an inlet opening (81), which is located at that end of the body (8) which it is difficult for medium to flow around which lies closest to the entry opening (2) of the housing (1), the hollow space (83) which passes all the way through the body (8) which it is difficult for medium to flow around having at least one outlet opening (82, 85, 86),
- the holder (6) having a hollow space (63) which passes all the way through it and has an inlet opening (61) and an outlet opening (62), the latter being connected to the inlet opening (81) of the body (8) which it is difficult for medium to flow around;
- and
- the holder (6) and the body (8) which it is difficult for medium to flow around being connected to one another and arranged in the housing (1) in such a way that, by means of an opening (5) in the housing (1) and via the inlet opening (61) of the holder (6), part of the mass flow which is to be mixed can be introduced into the through-flow chamber (4) via the at least one outlet opening (82, 85, 86) of the body (8) which it is difficult for medium to flow around.
The device (100) as claimed in one of the preceding claims, characterized in that furthermore there is a means for applying ultrasound to the body (8) which it is difficult for medium to flow around and/or to the mass flow at at least one location in the through-flow chamber (4).
The device (100) as claimed in one of the preceding claims, characterized in that furthermore there is a means for setting the body (8) which it is difficult for medium to flow around and/or part of the through-flow chamber (4) in ultrasonic vibration.
The device (100) as claimed in one of the preceding claims, characterized in that furthermore there is a means for applying laser light to the mass flow in the through-flow chamber (4).
