Embodiment Construction

[0025] The cavitation device shown in the drawing comprises a housing which surrounds a cavity and is designed in two parts such that it has a housing cover 1 and a housing cover 2 which can be tightly closed by means of this housing cover. The housing cover 1 is provided with a water inlet 3 and a water outlet 4, and both the water inlet 3 and the water outlet 4 communicate with the cavity. An electric motor 5 is flanged to the housing cover 2 . Furthermore, a mounting and holding device 6 is connected to the housing cover 2 .

[0026] A first annular structure 7 and a second annular structure 8 opposite to each other are arranged in the cavity. A first annular structure 7 (axially adjustable) is fastened internally to the housing shell 1 ; it forms a stator-annular structure 10 designed as a stator-annular disk 9 . In contrast, the second annular structure 8 is connected to a rotor-support structure 11 which is itself connected to a motor shaft 12 (protruding into the cavi...

Abstract

In a method for the treatment of water by cavitation in a cavitation device, the water to be treated passes through an annular cavitation zone (15) which exists between two mutually opposite annular structures (7, 8) which rotate relative to one another and which have teeth (16, 17) directed substantially axially towards one another. Here, the water flows along cavitation surfaces which are provided on the face sides of the teeth (16) of a first (7) of the two annular structures and which are inclined in the circumferential direction such that, viewed in the relative direction of rotation (B) of the other, second annular structure (8), the spacings between said teeth and said second annular structure increase. The invention also relates to a cavitation device suitable for use with the method.

Description

technical field [0001] The invention relates to a method for treating water by cavitation in a cavitation plant. Furthermore, the invention relates to a cavitation device which is specially designed and suitable for use in such a method. Background technique [0002] The world is paying more and more attention to all aspects of environmental protection. An important aspect of this is the cleaning of wastewater from domestic, industrial and commercial sources. [0003] This waste water can be loaded with various harmful substances. Accordingly, there is a series of different treatment methods, which can in principle be divided into mechanical, physical, biological and chemical methods. There have been some proposals to use cavitation to destroy harmful organic substances in the context of water treatment, especially wastewater treatment. The idea here is that the strong pressure pulses associated with the pressure extremes that occur during cavitation destroy or fragment ...
