Description

Process and apparatus for the physical heat treatment of liquid media

The invention relates to a method and apparatus for the physical heat treatment of liquid media and gases.

Conventional heat treatment methods and apparatus include heating elements by which they heat the liquid, preferably water or steam. The heating elements regularly consist of heating conductor materials, such as metal or semiconductor ceramic. These heating elements are connected to a power source. Other heating elements consist of heat exchangers which are heated by gas flames and in which water flows. Also known are electro-inductive Heating elements, as z. As disclosed in WO 2004/062320. Here, a non-contact heating element is arranged in the interior of the body and the body is wound by means of a controlled by a frequency source coil.

These devices require a complicated distribution of the heating medium and the power and gas connection. The contact surfaces of the heating elements are small, the heat treatment is uneven and the operation is uneconomical because of the costly. It is common for the heat supply to use steam, which heats a liquid, but this is very complicated and costly. The regulation of the heat treatment process is cumbersome and the speed of the heat treatment is low. The gas combustion products or the flue gases and the radiant heat are harmful to the environment. During the heat treatment, crystals are formed in the liquid which must be reduced and removed by chemical means.

Based on the above prior art, the invention has for its object to remedy this situation.

The object is achieved by a method according to claim 1 or by a device according to claim 7.

It can be seen that the invention is in any case realized if it concerns a method and / or a device for the physical heat treatment of liquid media, in which the hydrodynamically pretreated medium by means of a system electrochemical potentials and electrochemical signals RC AC polar and / or ionic action. It is advantageous if the hydrodynamically pretreated medium at the outlet and / or inlet is acted upon by the system of electromagnetic potentials having negative, electrochemical potentials. The flow of the medium through the system of electrochemical potentials and electromagnetic signals RC AC is preferably carried out several times. The size of the body with electrochemical potentials and electromagnetic signals is changeable and adaptable to the circumstances of the case. In the hydraulic circuit (compressed air circuit) of the hydrodynamically pretreated medium, preferably measuring instruments can be connected to the physical and / or chemical changes and energy changes in order to check the achieved parameters, For example, flow, temperature, conductivity, viscosity, pH u. Ä., To measure continuously. The positive electrode may preferably be made of a material having a positive, electrochemical potential, for example copper, carbon and the like. Ä., While the negative electrodes of a material with negative, electrochemical potential, such as iron, aluminum, stainless steel u. Ä., Can be formed. In an alternative embodiment of the invention, a tapered / depressed positive electrode may be formed as a type of source of ions and / or colloids. This engages in the electrochemical material of the positive electrode, which has an insulating layer of glass and Teflon at its periphery. This tapered electrode is separated from the hydrodynamically pretreated medium by an insulating layer, wherein a portion of this electrode is flowed around by the medium.

The electrodes forming the electrochemical potentials in the body of the alternative embodiment are preferably made of synthetic and natural minerals, ceramics and the like. A hydrodynamic treatment of the medium in the body can preferably be achieved with a tangential inlet and an outlet, but pointing against the flow direction, whereby a flow resolution is achieved. The advantage of the method and the device consists in its simplicity. As a hydrodynamically pretreated medium according to the invention, distilled and mineralized water, vegetable rapeseed oil, alcohol, petroleum, synthetic alcohol and propane-butane gas were advantageously used and tested. These media have undergone physical changes that have been characterized by an increase in temperature. During a multiple passage of the hydrodynamically pretreated medium through the device according to the invention, an increase of the water temperature from room temperature to 83 ° C was observed in about 4000 l of water. In this experiment, it was observed that the water stone present on the walls of the water tank was markedly reduced, with the result that this method is also advantageously applicable in the water and heat industry. The new, altered properties of the medium, in particular of the water, can also be used for cleaning surfaces in the laundry industry and for producing beverages in the food industry. It is also possible to change the oxidation and reduction properties of water and gas. These changes are proportional to the number of passes through the device.

By treating the medium according to the invention, the aggressiveness of water can be reduced in a simple manner. In addition, the water is sufficiently enriched with negative and positive ions of the elements, which leads to the reduction of corrosion of the line or the measuring instruments. In some cases, this treatment may prevent chemical water treatment. The effect is nature friendly. The efficiency of the heat treatment is very high, it can be a temperature of the medium up to 97 ° C can be achieved. By optimal dimensioning of the interiors of the body and their arrangement successively and side by side, it is possible to increase the efficiency of the method and apparatus for the physical heat treatment of liquid media in a simple manner. The invention will now be explained in more detail with reference to exemplary embodiments and the accompanying drawings. Show it:

Fig. 3 is a section A-A of FIG. 2 with a tangential inlet and outlet and

Fig. 4 shows an alternative embodiment of a positive electrode with a tapered electrode.

The device for carrying out the method according to the present invention consists of a substantially cylindrical body 1 of preferably insulating material, for example polyethylene, polypropylene, silicate ceramic or glass, in whose axis or in the vicinity of a positive electrode 2 is arranged. The electrode 2 is made of material having a positive, electrochemical potential, for example of copper, carbon and the like. In an alternative embodiment, this positive electrode 2 is completely or only partially separated from the hydrodynamically pretreated medium 9 by means of an insulating layer 23 formed from glass or Teflon. Along a part or along the entire length of the positive electrode 2 is at the periphery of an aluminum, stainless steel u. Ä., Negative electrode 3 is arranged with a negative, electrochemical potential. The body 1 has a first inlet-outlet opening 4 and a second inlet-outlet opening 5. These two openings 4, 5 can with respect be arranged on the body 1 either perpendicular, parallel to its axis, but preferably tangentially-eccentric, the second inlet-outlet opening 5 against the flow of the hydrodynamically pretreated medium 9, which flows through the first inlet-outlet opening 4, is arranged. Flow changes can thus be achieved if the surface structure of the positive electrode 2 and negative electrode 3 is changed, if appropriate if the shape of the latter is changed and the body 1 is dimensioned accordingly. It is advantageous if in the first inlet-outlet opening 4 and the second inlet-outlet opening 5, a first inlet-outlet electrode 31 and a second inlet-outlet electrode 32 is arranged. The designation for these electrodes is derived from contact with the hydrodynamically pretreated medium 9 in the body 1 rather than being arranged in the first and second inlet-outlet openings 4 and 5. These two electrodes can also be arranged in a hydraulic line outside the body 1 or they can be replaced by a part of the hydraulic line which is made of a material with a negative, electrochemical potential.

A control electrode 6 is located in the body 1, optionally outside the body with electrochemical potentials, and is supplied with the electromagnetic signal RC AC. For the specific embodiment, a frequency in the range of 150 to 400 Hz was tested, preferably 300 Hz ₁ with a power of 0.5 W.

When using a plurality of bodies 1, these can be arranged either in series or parallel to one another, with different volume size and different parameters, for example the frequency, the alternating electromagnetic field, the flow velocity and changes in the flow direction, or else flow distribution. In an alternative Embodiment, the positive electrode 2 at least at one end of a tapered electrode 22, which is located in a glass envelope which forms an insulating layer 21 and in the material having a positive, electrochemical potential, preferably carbon, as a source of ions and / or Colloid is introduced, and which is further separated from the material having a positive, electrochemical potential by an insulating layer 23. Such a positive electrode 2 is disposed in the vicinity of the material of the negative electrode 3. This solution is required in the case of aggressive water, in which a high corrosion of the metallic control and measuring instruments and also the lines forms. In this particular case, the tapered electrode 22 is formed of the same material as the control and measuring instruments with the greatest corrosion. In bacterial treatment, the material of the tapered electrode 22 is made of germicidal material, such as copper, silver, zinc and the like. By a single or multiple passage of the hydrodynamically pretreated medium 9 through the body 1 with electrochemical potential and electromagnetic frequency, there are physical, possibly chemical changes and energy changes. It is advantageous if the body 1 is arranged vertically and if in its upper part a closable gas circuit 7 and in its lower part a closable mud circuit 8 is arranged.

The hydrodynamically pretreated medium is preferably mineralized water, distilled water, service water or waste water, a polar and non-polar liquid or a gas. The positive and negative electrodes 2, 3, 31 and 32 of the alternative embodiment are formed of minerals, silicates, or artificial equivalents. In a further embodiment of the invention, the body 1 is arranged in a closed hydraulic circuit in which, for example, a flow meter, thermometer, viscosity meter and other instruments are located, with which physical or chemical Changes can be measured. This version is suitable as a measuring stand. It is advantageous if the positive and negative electrodes 2, 3, 31 and 32 have a roughened surface caused, for example, by a punching operation, a driving work or a pleating.

An advantageous embodiment of the invention provides that the substantially cylindrical body 1 has a length of 510 mm and consists of polypropylene (PPR). The outer diameter of the body 1 is about 63 mm, while its inner diameter is about 42 mm. The axis of the inlet-outlet opening is perpendicular to the axis of the body 1. In and around the axis of the body 1, the positive electrode 2 and the control electrode 6 made of quartz glass with a diameter of about 12 mm are arranged. In the electrode 6 is carbon in powdery form, the z. B. completed by epoxy and bound. In the control electrode 6 is a spiral electrical conductor made of copper, whose diameter can be 0.1 to 3 mm and whose length 200 to 2000 mm. The conductor is connected to a frequency signal RC AC 150 to 450 MHz _1, preferably 300 MHz. In general, frequency ranges from 30 MHz to 5 GHz with a power of 0.1 to 3 W come into consideration. The positive electrode could also consist of a copper bar with Teflon coating. The glass coating or the Teflon layer need not be distributed over the entire surface of the positive electrode 2.

The conductor is connected to a frequency signal RC AC 150 to 450 MHz, preferably 300 MHz. In general, frequency ranges from 30 MHz to 5 GHz with a power of 0.1 to 3 W come into consideration. The positive electrode could also consist of a copper bar with Teflon coating. The glass coating or the teflon layer do not have to be over the whole surface of the be distributed to positive electrode 2. It is expedient if the positive electrode is not in contact with the medium 9. The negative electrodes are made of aluminum, preferably of a bent piece of sheet metal, which is in contact with the medium 9. However, it could also be coated with Teflon. Electrodes with insulating coatings are used in the polarization regulator, while electrodes without insulation are used for the ionization control of the apparatus. The capacity of the circulating pumps used can be between 20 W and 3,000 W. For heating the distilled water from room temperature to 50 ° C 1, 5 to 2.5 m ³ / h were circulated at a speed of 50-79 m / s. An optimization or increase in performance of the system can be achieved by increasing the electromagnetic potentials between the electrodes and / or by increasing the power of the RA AC signals. Very good results can be achieved with a body 1 having eccentric, tangential arrangements of the inlet / outlet ports with diameters of 12, 18 and 36 mm. As a result, a decay of Stromverwirbelung is achieved by changing the current orientation. The medium speed is 0.5 to 150 m / s. In lonisationsbetrieb the plant, the internal density of CU, AI, etc. is about 0 to 1 g / m ³

The applications of the invention are given by the magnitude of the changes in the physical properties of liquids and lanes passing through the device. The changes are proportional to the number of passes through the electrochemical potentials, possibly the application of the control electrode. The application can be used in the enrichment industry of drinking and industrial water, industrial and waste water, construction, balneotherapy and spas, cleaning and laundry, food industry, alcohol production, brewing, health care, dermatology, in the ceramic production and heat generation, in the heat industry, in sewage treatment plants, in the energy industry, in water sources, outdoor pools, also in the processing industry the oil industry and the automotive industry and similar industries.

Because of increased crystallization of the carbonates, it is advantageous in the course of medium heating to minimize the oxidation. This can be achieved by the fact that the treated medium comes into contact with a negative electrode, in particular from Al, on leaving the device. Of importance this is z. As in the treatment of aggressive water in pits. When repeated passage of the medium through the devices it comes to the medium to light effects, which is for special purposes, eg. B. work, can be used.
