Abstract
A cavitation device is provided for use in a method for the treatment of water by cavitation. The water to be treated passes through an annular cavitation zone which exists between two mutually opposite annular structures which rotate relative to one another and which have teeth directed substantially axially towards one another. Here, the water flows along cavitation surfaces which are provided on the face sides of the teeth of a first of the two annular structures and which are inclined in the circumferential direction such that, viewed in the relative direction of rotation of the other, second annular structure, the spacings between said teeth and said second annular structure increase.
Claims13
A cavitation device for use in a process for treatment of water by cavitation, comprising:
- a housing with a water inlet (3), a water outlet (4) and a cavity extending between the water inlet and the water outlet as well as two annular structures (7, 8), which are disposed opposite one another in the cavity and which are provided with teeth (16, 17) axially oriented in substantially opposite directions and which define an annular cavitation zone (15),
- wherein, at the end face, on the teeth (16) of one of the two annular structures (7, 8), cavitation surfaces (23) are provided that are inclined relative to a reference plane perpendicular to a rotational axis of the corresponding annular structure in a circumferential direction relative to a circumference of the corresponding annular structure in such a way that, viewed in relation to a direction of rotation (B) of the other annular structure (8, 7), the cavitation surfaces increase their spacing relative to the other annular structure;
- wherein the cavitation zone (15) can be flowed through from inside to outside, by the fact that the water inlet (3) and the water outlet (4) are respectively in fluidic communication with a region of the cavity disposed radially inside the cavitation zone (15) and with a region of the cavity disposed radially outside the cavitation zone,
- wherein the cavitation surfaces are provided with outer guide ridges radially outside the corresponding cavitation surface and inner guide ridges radially inside the corresponding cavitation surface which maintain a substantially constant spacing relative to the other annular structure.

- wherein the rotor annular structure (14) is constructed as a rotor annular disk (13), which is mounted on a rotor support structure (11) driven in rotation by a motor (5) and disposed in the cavity, and
- wherein the rotor support structure (11) is constructed as a flow-through, central water-guiding body (27), which is provided with a radial outlet slit (29), which is substantially aligned with the slit existing between the two annular structures (7, 8).
