  • the cavitation consists in the formation of cavities filled with steam gas on the edge of the cylinder due to a local reduction in pressure caused by the movement of the liquid.
  • the mixing and dispersing effect of the hydrodynamic cavitation is the result of a multitude of force effects of the bursting cavitation bubbles on the fiber-liquid mixture to be processed.

  • the boundary of the separation of the compact phases is destroyed, ie their erosion.
  • a dispersion medium and a dispersion phase are formed.
  • the encoded fiber material suspension is fed via the exit opening to an overflow vessel, from which the smaller part of the cavitated fiber material suspension is passed into an end product container and the overflowed larger part is pumped back into the inlet opening of the device via a return container.
  • the problem with this known device is that it lacks sufficient effectiveness in the process of dispersing the fiber materials because the intensity of the cavitation field that is created is not high enough despite pumping back the overflowed larger part of the fiber material suspension that has already cavitated.
  • the use of an overflow vessel and the undetermined return of the overflowed part lack a defined regulation of the intensity of the cavitation field. This limits the technological application possibilities of the known device.
  • the invention is based on the object of specifying a device for producing liquid systems, in particular emulsions, suspensions or the like in a cavitation field, which has a suitably designed cavitator and a suitable construction which make it possible to generate a high intensity of the cavitation field and regulate this intensity.
  • the object is achieved in that in the device according to the invention there is a housing which has an inlet opening for the supply of at least one component stream and an outlet opening for the removal of the cavitated liquid system and an inlet part, a confuser, a passage chamber with a difficult to flow around body, a Difi-usor and an output part, which are arranged one behind the other and firmly connected.
  • the body, which is difficult to flow around is arranged axially to the central axis of the flow chamber at an intermediate part which is fastened to the wall of the flow chamber.
  • the body which is difficult to flow around is designed as a truncated cone, the large base of which is directed towards the outlet opening and which represents a combination of several partial bodies which are difficult to flow around, between each of which there is a cavity through which flow can pass.
  • the partial bodies that are difficult to flow around are mostly physically designed surfaces, in particular the base surfaces or the lateral surface of the truncated cone.
  • the cavities present between the partial bodies are essential. Partial bodies that are difficult to flow around also generate cavitation fields with appropriate local tapering of the component flow. If there are several partial bodies of this type, several cavitation fields are created.
  • a line that is mounted between the output part and the flow chamber in front of a cavitator and in which a control element is arranged can be controlled in a controllable manner, such as a defined, returned and re-inflated part of a already cavitated liquid system influences the cavitation fields behind the truncated cone areas and thus a supercavitation field as a summary cavitation field.

  • An advantage of the invention is that the superposition of two cavitation fields creates a supercavitation field with intensive micro-processes. Conditions are created for coordinated bursting of entire groups of cavitation bubbles on a local scale with simultaneous formation of voluminous pressure waves of high energy, the spreading of which intensifies the decay of the cavitation caverns and the bursting of entire groups of cavitation bubbles that are in the process of bursting. In the case of coordinated bursting of entire groups of cavitation bubbles with the same characteristic dimensions, the intensity and the energetic potential of the cavitation field are many times higher than with individual, uncoordinated bursting of the bubbles. In this way there is a concentration of energy and an erosion effect on the current of the components that are processed.

  • the invention also opens up the possibility of regulating the intensity of the resulting hydrodynamic supercavitation field according to the technological processes.
  • the increase in the intensity of the cavitation field and the reliability of its regulation are due to the presence of an adjustable return, the supply of components via the ejector contained in the first cavitator, the cone ratio of the two bodies which are difficult to flow around, from 15 to 75% (mostly 60%) elastic elements, which have a thickness of 0.01 - 10 mm, and the diameter ratio of the elastic elements to the lamellae of the truncated cone in the range of 0.3 - 0.9 is guaranteed.
  • the flow of the components to be processed is distributed uniformly in the passage chamber. It is ensured that behind each of the truncated cones and each of its sub-bodies the same hydrodynamic conditions are present for the creation of own hydrodynamic cavitation fields.
  • the design of the bodies which are difficult to flow around in the form of truncated cones with different cone opening angles creates the condition for the fact that they generate the cavitation fields which differ in intensity.
  • Behind each of the bodies and sub-bodies, in terms of structure and size different, non-stationary, intermingling caverns are formed which form cavitation bubbles with a size in the area of increased pressure, which determine the structure of the cavitation fields created.
  • cavitation fields work with each other and ensure that the bubbles are mixed intensively and through them the flow of the components to be processed is saturated in the entire passage chamber. Due to the polydisperse structure of the cavitation fields, the individual concentration of the cavitation bubbles increases in a zone where they burst (bursting zone), which increases the cavitation effect during processing. The different diameters of the bodies and sub-bodies also cause a different frequency of tearing off the cavitation caverns which form behind these. For this reason act in the Splitting zone on the cavitation bubbles polyfrequency pressure pulses, which form the conditions for the coordinated bursting of entire groups of cavitation bubbles of the same size.
  • the pressure waves that arise at the following cavitator increase the pressure in the bursting zone, and the broad spectrum of polyfrequent pressure pulsations not only affects the bursting cavitation bubbles, but also the cavitation cavities that mix in the stream by accelerating their destruction and thus intensify the process of mixing, dispersing or emulsifying the components to be processed.
  • a further advantage of the invention in the design of the truncated cones arranged one behind the other is that the longitudinal and radial resonance vibrations of the second cavitator, which arise under the influence of the cavitation field that forms behind the first cavitator, also contribute to increasing the intensity of the supercavitation field.

  • the additional potential energy accumulated makes it possible to obtain a large interphase surface of the components of the current to be processed.
  • the pulsations of the cavitation fields which are caused by the second cavitator and in particular by the elastic lamellae, contribute to the formation of additional cavitation bubbles in the entire flow chamber, which increases the erosion effect of these fields on the flow of the components to be processed.
  • the partial bodies preferably the fins, are made from elastic, non-metallic material. But they can also be covered with a layer of elastic, non-metallic material, such as rubber.
  • the intensification is due to the high energy potential of the cavitation fields that are created, which is intensified by the vibration of the non-metallic material and the reflection of the pressure waves.
