Definitions

  • the invention relates to a hydrodynamic cavitation mixer.
  • the so-called cavitation bubbles occurs near the interface between two phase regions, say large oil droplets in water, the second component, in this case the oil droplets, is torn into smaller units and thereby a very fine mixing of the two components and thus produces a very stable suspension or emulsion.
  • cavitation bubbles is done in a flowing liquid by a drop in the static pressure below the vapor pressure of the liquid, thereby forming vapor-filled gas bubbles, eg. B. due to a current narrowing.
  • the static pressure becomes zero or negative in the case of water when the flow velocity reaches a certain value dependent on environmental conditions, e.g. B. at the trailing edges about 14 m / sec., Exceeds.
  • the constriction and subsequent expansion of the flow cross section can be achieved by an obstacle body is arranged in a flow chamber, wherein the remaining gap z. B. between obstacle body and surrounding housing of the flow chamber forms the bottleneck.
  • cavitation fields forming in the cavities field form in the cavities between the obstacle bodies, and the spatial superposition of the individual cavitation fields creates a so-called super-cavitation field, which causes a multiplication of the cavitation effect of each individual cavitation field.
  • the reduction of the annular gap area in the direction of flow is z. B. caused by a decreasing in the pressure flow direction cross section of the Kavitatorrohres and a particular smaller analog diameter obstacle, so the obstacle body on the axial rod, and the axial displacement of the entire Obstisbäumchens relative to Kavitatorrohr by the Axialstange of Obstacle tree axially from a closed end the Cavitatorrohres is led out and can be adjusted axially there.
  • Kavitatorrohr composed of several individual parts, especially in the axial direction adjoining individual parts, but also from two split in the longitudinal half shells, so must be arranged between gaskets that leave between seal and surrounding material smallest cavities in which collect and multiply germs can.
  • the individual parts which are to be joined together usually to be screwed, must fit tightly against one another and as cavity-free as possible in order to reduce these possibilities of contamination as far as possible.
  • the cavitator tube is made from as few as possible, in particular a single piece, then either the production effort is very high or the assembly of the obstacle tree to be arranged therein is not possible or very expensive.
  • welds are in areas in which only laminar flows prevail during operation of the cavitator, these areas are not optimally self-cleaned by the flow of the medium.
  • Kavitatorrohr consists of individual sections, in particular separate sections for product inlet, Kavitationskonus and AxialstangenDurch Insert in the flow direction one behind the other, arranged on these individual pipe sections welds can be achieved before Georgiaflanschen well and the welds are reworked, in particular sanded or otherwise and manner of the surface of the weld to be eliminated to the interior of the cavitator out.
  • the Befest onlysfla n cal are not welded to these individual pipe sections but made in one piece with these pipe sections from the solid, in particular turned from solid, so that no welds arise that can raise the problems described.
  • the discharge chamber which contains the radially outflowing product outlet, is a purchased as a purchased part tee, which thus may indeed have a weld between the radial pipe section and extending in the longitudinal direction pipe section, but this weld was pore-free treated by the manufacturer, which is possible in mass production and specialized devices.
  • the required flanges are welded and the welds aftertreated to close pores.
  • gap-free seals in particular so-called germ-free seals, are used, which prevent the deposition of germs for lack of residual space between seal and surrounding material and in the seal.
  • the arrangement of seals is recommended in such a manner that the main flow direction does not coincide with the direction of the seals, so the seals are preferably arranged in the circumferential direction or radial transverse direction of the main flow direction, and thus the individual sections of which the Kavitatorrohr consists , connect to each other in the axial direction.
  • the transitions between the obstacle bodies and the axial bar carrying them executed rounded, in particular with a radius of curvature of at least 1 mm, better at least 10 mm, and also all inner edges , In particular annular inner edges, on the inner surfaces of the cavitator, in particular the inner edges between cylindrical and conical sections of the cavitator.
  • a very critical area from a hygienic point of view is still the passage of the axial rod through the front end of the closed Kavitatorrohres, namely the portion of the Axialstangen take arrangement.
  • the annular gap between the axial rod and the receiving, surrounding component is preferably sealed with a gap-free, in particular germ-free, seal such as a lip seal and only in the simple case of an O-ring seal.
  • the product inlet preferably takes place for the main component in the axial direction through a corresponding opening in the product inlet, wherein the components to be added are supplied at a lower proportion than the main component preferably via corresponding radially outflowing supply lines in the product inlet, and preferably in or before the first cross-sectional constriction in the section of product enema.
  • baffle By forming the first obstacle body as a baffle plate, so with one of the flow direction of the first component as strong a obstacle bidding, baffle, which is even or concave against the onflowing first component, alternatively by this first obstacle body through countercurrent second Component be supplied so that the two components in the area at or immediately before the Already by the impact of the first component, the impact surface should be strongly mixed with the baffle plate.
  • an already existing mixture may be processed with an analogous device for the purpose of stabilization, by then supplying the mixture to be stabilized instead of the first component, and no further component being supplied beyond, thus also no inlet opening for the second Component as well as a supply piping is needed.
  • the impact and the mixing is therefore particularly strong mixing, because beyond the first obstacle body, the flow direction of the first component counteracting, no support the flow is opposed, because this first as well as the following obstacle bodies can be formed on a particular in the form of a central axis Holder, which approaches from the opposite direction, ie opposite to the flow direction of the first component, are held in the center of the flow chamber.
  • a cross-sectional constriction and then a cross-sectional expansion both preferably in a cone shape, passes through the cross-sectional expansion, a negative pressure generated by the first component in the flow chamber in front of the baffle plate, which supplies the second component into the flow chamber sucked in and also improves the mixing.
  • a smaller in terms of its area flow gap measured in the main flow direction ie the flow direction of both the first component alone and the mixture from the supply of the second component, can be achieved in particular in combination with the impact of the first component on the first obstacle body that the Remove obstacle body in its cross section in the main flow direction and so that the length of the annular gap around the obstacle body around, and thus form a narrowing in the flow direction cone.
  • the wall of the surrounding housing can run parallel to the cone of the obstacle body or even be formed more conical (larger angle at the apex of the cone), which further increases the effect of the decreasing annular surface.
  • a weaker cone shape (lesser angle) at the top of the cone of the housing is possible, which weakens the effect caused by the conical shape of the obstacle body somewhat.
  • the concavely formed impact surface causes - above all with more or less centric impingement of the first component on the baffle plate and centric feeding of the second component - an approximately toroidal turbulence of the mixture and thereby a new approach of the rebounded from the baffle mixture to the baffle, where the mixture is additionally mixed again by the again impinging first component.
  • the effect can be further improved by the supply of the second component on the baffle of the first obstacle body is not distributed centrally, but decentralized distributed at several input openings annularly around the center of the baffle, and the impact of the first component remains central.
  • the central axis for fixing the obstacle body can be used at the same time hollow as a pipe for feeding the second component to the baffle.
  • the mixture produced is discharged via an outlet opening, which flows out of the housing preferably radially, in particular in the form of a radial annular gap.
  • the efficiency of the device which is usually used in an existing pipeline, can be increased by - for example, depending on the flow rate in the feeding tube, the viscosity of the individual components and their miscibility - the obstacle bodies are axially adjusted, in their Distance to each other and / or in groups or even total relative to the surrounding housing, whereby in a conical housing and the absolute size of the annular gap surfaces is changed.
  • the obstacle bodies are on the one hand plate-shaped in order to simplify and reduce production, and in particular are made so thin that they can oscillate at their free edges in the direction of flow, which facilitates the generation and tearing off of vapor bubbles.
  • the flow gap between obstacle bodies and housing can at z.
  • the plate-shaped obstacle body at its radially outermost point quite reach the housing and are connected to this, but not for example over the entire circumference, but only in segments, and in the segments between radially extending slots or gaps are present, which can be offset from each other in the axial direction from one obstacle body to the next and serve as flow-through gaps.
  • the surrounding housing - viewed in the axial direction - may be formed analogously, so that over the entire circumference a respective constant cross section between the housing and spoiler edge is met or the housing is formed inside continuously round, so that change in the circumferential direction, the distances to the trailing edge.
  • the cross-sectional constriction should be dimensioned after the inlet opening so that the flow velocity at the narrowest point of the cross-sectional constriction corresponds to the flow velocity in the flow gap of the last obstacle body.
  • the flow rate behind it, at the outlet after the last obstacle body should be slightly higher than in the flow gap at the last obstacle body.
  • a particularly simple embodiment is provided when round disks with a diameter that remains the same in the flow direction are used as obstacle bodies, and the decreasing annular gap is achieved by the housing tapering in the main flow direction.
  • this effect is less pronounced than with conically smaller obstacle bodies, in particular slices.
  • a strong cross-sectional constriction downstream of the inlet opening is particularly advantageous, so that the flow velocity increases by a factor of 9-13, in particular by a factor of 10.sup.-12, in particular by a factor of 10.5-11, from the inlet opening to the narrowest point of the cross-sectional constriction. 5, increased.
