Definitions

  • the invention relates to a process for producing a reaction product from a gas and a liquid, the gas being present under normal conditions in an activated form and in an amount which is at least 30% above the saturation amounts corresponding to the normal conditions for dissolving the gas in the liquid the preamble of claims 1 to 3; and an apparatus for performing the method according to the preamble of claim 6 and claim 11.
  • the dissolution (solubility) of gases in water is proportional to the partial pressure of the gas over the solution.
  • gases in liquids these are generally introduced into the liquids.
  • the maximum amount of gas absorbed at a given temperature is the saturation concentration. It increases with the falling temperature of the liquid. Increasing the partial pressure of the gas above the liquid results in supersaturation of the liquid-gas mixture, but after the partial pressure has been reduced, the excess of dissolved gas, which is then no longer soluble, is gassed off.
  • DE-C1-3543002 discloses a device for the gassing of liquids, gas being introduced into liquid from a chamber via an elastic chamber wall that vibrates.
  • a helical flow can be maintained in a reaction vessel if the feed is introduced tangentially into the reaction space at one or more points.
  • Such devices are also known as cyclones or centrifugal separators; they are used to separate solid substances from gases or liquids.
  • DE-C-967943 uses this flow phenomenon for intensive mixing of the reaction participants when carrying out endothermic, chemical reactions.
  • a similar device is known as a Hilsch pipe, in which a gas that is cold on the inside and warm on the outside is created around the pipe axis when blowing in gases. All of these methods are not suitable for introducing gas into a liquid suitable for the use according to the invention, and for introducing gas into the liquid in a form and quantity desired for the use according to the invention.
  • EP-A1-0314015 describes a method in which a gas is "bound" in water, and in particular above the saturation value under the corresponding normal conditions.
  • the gas is introduced into the water via a vortex thread.
  • a container is provided, hereinafter referred to as a perturbator, which is connected via hose lines to a reaction chamber, hereinafter referred to as converter, in a closed circuit, a liquid-promoting pump being provided in this circuit.
  • the therapeutically effective water-oxygen reaction product in which the oxygen becomes active beyond the reactivity achieved in dissolved form, remains without special measures, such as Storage under elevated pressure or temperature, stable for a long time, and the half-life is at least one month, usually even a year.
  • the method according to the invention uses the known, vortex-generating mode of operation of a cyclone, combined with additional process steps including a smooth flow path and, as a result of an uninterrupted, expanded, preferably repeated, cycle, potentiated in effect, as in the characterizing features of claim 1 and of claims 2 or 3.
  • Advantageous developments of the method are described in the features of claims 4 and 5.
  • the reaction chamber or the converter of EP-A1-0314015 is only suitable to a very limited extent, due to the shape described, to ensure a uniform, rotating flow movement.
  • the channels leading into the interior of the converter do allow an approximately tangential inflow direction.
  • the channels should on the one hand also be inclined against the closed apex of the converter interior and on the other hand their mouth openings on the inside should still be below the largest diameter of the converter interior (in seen in relation to the flow direction).
  • the special measures consist in introducing a gas into a liquid in a multi-part device, preferably consisting of three, partly cyclone-like devices, which are referred to as the perturbator 1, spinner 2 and converter 3, this mixing being carried out continuously in a circuit for several hours, preferably operated for at least 36 hours (Fig. 1).
  • Perturbator 1, spinner 2 and converter 3 are connected by hose lines 6 to form a closed circuit.
  • the perturbator 1 consists of an approximately pear-shaped container 7 with a volume of, for example, 20 liters. Its three-dimensional shape is conceivable composed of a hollow spherical cap with a diameter of approx. 40 cm and a cone or (Fig. 2) a hyperboloid, which is created by the rotation of a hyperbola 29 about the axis of symmetry 24 of the container 7. If this spatial shape also proves to be particularly suitable for the course of the process, good process results are achieved, in particular even if the rotary body is designed differently but always in a funnel shape (for example with dashed lines).
  • the tube extension 21 is preferably inserted obliquely into the wall of the perturbator 1, in such a way that its axis 36 points obliquely from bottom to top, about 15 ° against the equatorial plane BB of the perturbator 1 - preferably opening below it - and with the plane passing through the axis of rotation 24 and the center of the tube attachment 30 encloses an angle of approximately 45 °.
  • the container 7 is filled with a liquid up to a filling height 9, specifically via a filling opening 10 with an inner diameter of approximately 30 mm, which sits gas-tight on the top of the container 7 and can be shut off in the operating state (see also FIG. 4).
  • a gas inlet 12 with a clear width of 8 mm, which can be shut off by means of a valve 8, and a connection 13 for measuring devices (not shown).
  • a gas space 14 into which gas, for example pure oxygen, has been introduced via the gas inlet 12.
  • the perturbator 1 is connected via a hose line 6b, any intermediate units 4 and a hose line 6c to the spinner 2, which is designed as a cyclone-like mixing device for the liquid-gas mixture. It serves as an auxiliary unit between the perturbator 1 and the converter 3 and is still in front of the pump 5.
  • the spatial shape of the spinner 2 corresponds to a hollow egg which is drawn out too funnel-shaped and opens into the hose line 6d to the pump 5 via an outflow opening 18.
  • the supplying hose line 6c opens into the spinner 2 via a tube part 16, the axis 37 of which slants from bottom to top at an angle of approximately 10 ° to the equatorial plane FF of the spinner 2, possibly opening above it, and at an angle of approximately 45 ° a plane determined by the axis of symmetry 17 of the spinner 2 and the center of the inlet opening 31 is defined.
  • the spinner 2 has a diameter at its equatorial plane FF which is at least twice the diameter of the supplying hose line 6c is.
  • the outflow opening 18 of the spinner 2 is connected via a hose 6d to a preferably magnetically coupled pump 5, which has a minimum output of preferably 25 liters / min for the 20 liter perturbator system.
  • a hose line 6e leads from the pump 5, the cross section of which is approximately 10 to 15 mm smaller than the cross section of all other hose lines which are dimensioned with 20 mm to the lower inlet 19 of the converter 3.
  • the "heart" of the converter consists of a preferably egg-shaped hollow body 25 (length approx. 7 cm, diameter approx. 3.5 cm), in the wall of which in a plane parallel to the equatorial plane DD of the hollow body 25 there are several channels 11 which run obliquely downwards flow tangentially.
  • the axes of the channels 11 are inclined against the equatorial plane DD and against the axis of symmetry of the hollow body 25 by preferably 45 °. If the mouth ends of the channels 11 in the interior of the hollow body 25 lie below the equatorial plane DD, an optimal, cyclone-like functioning of the hollow body 25 is ensured.
  • This egg-shaped hollow body 25 is introduced into an outer hollow body 39, firmly and seamlessly connected to it, in such a way that the egg-shaped hollow body 25 is held in a ring shape above the channels 11.
  • This holder 27, which surrounds the upper part of the egg-shaped hollow body 25, is perforated in the form of a channel in its center, and thus also at the apex of the egg-shaped hollow body 25.
  • the device shown in FIG. 1, which consists of a perturbator 1, a spinner 2 and a converter 3, represents only one variant of carrying out the method. If the method is carried out using only one perturbator 1 and one converter 3, as described, for example, in EP-A1-0314015, the process time is increased.
  • one (or more) perturbator (s) 1 can also be provided.
  • the position of the individual devices in relation to one another and in space is not necessarily fixed.
  • the axes 17 and 38 of spinner 2 and converter 3 can be inclined or even horizontal, so that the designation "top” and “bottom” used in the description for various device parts is only to be understood relatively with reference to the drawing.
  • the perturbator 1, as a liquid-absorbing apparatus, must of course be positioned vertically, preferably in such a way that no other part of the device comes to lie above the level determined by the fill level 9 for the liquid.
  • the entire system In the operating state, the entire system, with the exception of the gas space 14, is filled with liquid, in particular water.
  • liquid is conveyed in the direction of the arrows 22, a vortex being created by the tangential inflow of the water into the container 7.
  • the surface of the water In the container 7, the surface of the water is changed from its rest position 9 into the funnel position 23 shown in broken lines, with oxygen from the gas space 14 in the form of bubbles in the liquid is sucked and conveyed further according to the arrows 22 in the system, or is sucked and pressed.
  • a gas space is formed during the course of the method, which largely fills the cavities 25 and 40.
  • the liquid-gas mixture flows, corresponding to the arrows 22, tangentially into the hollow body 25 via the channels 11, a liquid-gas jacket rotating on the inner wall is formed there, which with increasing rotational speed at the lower end of the hollow body 25 reverses and swirls along the axis 38 in the form of a rapidly rotating vortex filament against the outlet nozzle 28, where it breaks off into the smallest liquid-gas mixture droplets and, with suitable dimensions, forms a vortex system behind the nozzle edge.
  • the expanded upper hollow body 40, into which the liquid-gas mixture is injected acts like a diffuser.
  • the particles of the liquid-gas mixture should have a maximum diameter of approx. 0.01 ⁇ m with suitable dimensioning of all components and a suitably selected pump output.
  • the gas bubbles are distributed more and more finely by the treatment in the various apparatuses.
  • the resulting mixture is drawn off via an outlet valve 33 arranged in the hose line 6b, for example.
  • the process runs over several hours, preferably for at least 36 hours, during which the gas obviously attaches to the liquid molecules, or imparts an activated structure to the liquid over a long period of time.
  • cooling is also provided which keeps the circulating mixture at only 15 to 18 ° C .; In terms of energy consumption and the desired result, this means a rationalization of the process.
  • the mixture enters the bottom of the coil, which is located in a pot through which the cooling medium flows.
  • the spatial shapes of the perturbator 1 described in FIGS. 1 and 2a are possible design variants.
  • the one shown in Fig. 2b is characterized by particularly good results.
  • the spatial form composed of two semi-hyperboloids, which have the axis of symmetry 24 '' as the axis of rotation. These hyperboloids are connected to each other by a flat, barrel-like middle piece without kinks.
  • This spatial shape variant like the spatial shape shown in FIG. 2a, has the advantageous property of assigning an ever smaller diameter to the vortex formed during the method, and thus increasing the rotational speed of the vortex funnel.
  • the container 7 of the perturbator 1 is also possible, which is designed to correspond to an inverted, wide bottle with an approximately funnel-shaped neck.
  • the upper part 7 ′′ or 7b is cylindrical, spherical cap, conical or hyperboloidal, the lower part 7 ′ or 7a conical or hyperboloidal, the corresponding connecting middle part 35 is barrel-shaped or cylindrical, it shows in all these cases that the height h of the lower container part 7 'or 7a is chosen to be as large as possible in relation to the radius r of the perturbator container 7 (FIG. 2b).
  • the vertebral thread 26 that is important for the method is then longer and therefore more effective.
  • FIG. 4 shows a compact arrangement of the components spinner 2, perturbator 1, converter 3, pump 5 and coil 4 within a device cabinet 41, which at the same time takes over the function of the cooling unit.
  • This arrangement which can be designed, for example, as a 20 liter, 10 liter or even 5 liter system, based on the liquid content, could be used in medical practices, therapy centers, health centers and the like. prove.

  • FIG. 5a to 5c schematically show arrangement variants for carrying out the method according to the invention, in which neither a perturbator 1 nor a converter 3 is required. Since this latter component in particular has a relatively complicated structure, it will be preferable to replace it with components which are simpler and thus cheaper to produce.
  • the perturbator 1 other devices can be used, by means of which gas can be introduced into liquid in a manner known per se. The effectiveness of the gas uptake is increased by passage through a plurality of spinners 2, by one or more helices 4 and by continuous passage and repetition of the same cycle.
  • Figures 5a, b and c show the fairly wide freedom in the number and choice of components that can be used (for the sake of clarity, cooling units have not been shown).
  • FIG. 5 a provides a gas introduction device in the form of a vibrator 49, gas being introduced into the liquid from a gas space in a known manner via a vibrating membrane provided with fine holes. This arrangement is provided instead of the perturbator. This introduction of gas should take place throughout the process. When running through the circuit, the liquid-gas mixture flows through the mixing tank of the vibrator again and again, and there is always the possibility of introducing additional gas into the gas-liquid mixture.
  • a suction device 50 for the gas from a gas reservoir 46a is provided, the mode of operation of which corresponds to the principle of a water jet pump.
  • the device of FIG. 5c instead contains an atomizer 51, which brings liquid into the gas-filled container, which is finely atomized, and which is provided instead of the perturbator.
  • the liquid-gas mixture passes through the Circuit in the manner described above, but in addition to increasing the effectiveness, can be atomized into the gas atmosphere several times via the atomizing device, which can be in the form of a nozzle or a centrifugal atomizer.
  • a variant of this is to atomize the liquid in an atomizer 51 and to supply gas to it pulsatingly via a pressure wave generator 53.
  • a fundamentally different way of letting the process run is to introduce gas into a liquid under increased pressure and / or reduced temperature, i.e. thus to dissolve in it and to subject this gas-liquid mixture, for example, to a circuit corresponding to FIGS. 5 a to c, the pressure being lowered gradually and / or the temperature being increased until normal pressure or normal temperature is reached. Then a pressure vessel would have to be provided instead of the perturbator, which regulates the pressure in the vessel and thus also in the circuit via compensating valves; In order to be able to set the required temperature, the entire circuit should advantageously run in a thermostat-controlled environment (housing).
