The field of technology.

The present invention relates to the field of processing liquids, preferably hydrocarbon fuels, water and aqueous solutions, liquids of living organisms by an alternating electromagnetic field. The invention can be used in industry, thermal energy, utilities, agriculture, medicine, everyday life, transport and other industries where a qualitative change in the physical properties of liquid media is required. The prior art.

The invention is known "METHOD AND DEVICE OF INDUCTION HEATING OF LIQUIDS" (RU 2444864). In the proposed method and its device for heating a container with a liquid, a resonant self-oscillating mode of an electromagnetic field of increased frequency f ₀ = 1-100 kHz is created in the inductor coil of the heater and the obtained electromagnetic field is applied to the material of the heated container and liquid in the frequency range of the maximum losses in the container material while measuring the temperature of the heated fluid at the outlet of the tank, compared with a predetermined value, and in accordance with this, maintain the temperature of the heated fluid STI at given parameters. In another embodiment of the method and device, the transfer of electromagnetic energy from the converter to the inductor winding is carried out using a high-frequency resonant transformer through a single-wire waveguide line. In this method of induction heating of liquids, an alternating magnetic field is created and the created field is applied to the material of the heated container with liquid; to heat the container with liquid, a resonant self-oscillating mode of an increased frequency electromagnetic field f ₀ = 1-100 kHz is created in the inductor coil of the heater and is exposed to the obtained electromagnetic field on the material of the heated container and liquid in the frequency range of the maximum losses in the container material. In this method and device, a similar feature with the claimed invention is the use of an alternating electromagnetic field. The difference is that to obtain an alternating electromagnetic field, a resonant self-oscillating mode of the electromagnetic field in the inductor coil of the heater is used, and a frequency and voltage converter having an output voltage with a resonance frequency of the self-oscillating mode is used to excite the resonant self-oscillating mode. Moreover, this method and device are used only for heating liquids in steel products such as tanks, tanks, pipelines, radiators, dishes through metal walls, using these products as part of an induction system. The invention is known "METHOD FOR INCREASING EFFICIENCY OF COMBUSTION OF HYDROCARBON FUEL" (RU 2562505). In this method of increasing the combustion efficiency of hydrocarbon fuel, the frequency of the alternating low-voltage (10-600 V) voltage at the electrodes is changed and the frequency of a uniform electric field transverse to the fuel flow created in the fuel is selected at which the dielectric loss in the hydrocarbon fuel is maximum and the dielectric loss tangent tg6 is also will be maximum. In this case, the frequency of the alternating electric field, the reciprocal of the relaxation time of the molecules excited in the electric field in the fuel, is selected and the hydrocarbon fuel is treated with an electric field before it is fed to the nozzle. In this method, a similar feature with the claimed invention is the use of an alternating electromagnetic field. The difference is that in this method, electrodes in contact with the fuel are used to expose the fuel to an alternating electric field and the characteristics of the alternating field and the method for producing it are not given. A useful model is known "INDUCTION DEVICE FOR HYPERTHERMIA" (RU 170891) An induction device is designed to heat implants used in tissue-replaced cancer surgery with a high-frequency magnetic field. Implants provide local temperature effects on surrounding tissue. The composition of the implants includes ferromagnetic particles that ensure their heating. The inductor of the device is a ring of flat conductive tape inside which the patient’s body is placed. An inductor is included in the series resonant circuit as an inductance. The frequency of the magnetic field does not exceed 500 kHz, which excludes direct heating of biological tissues. The inductor provides the creation of a high-frequency magnetic field of the required geometry with an intensity of up to 8 kA / m. The resonant circuit is made with a resonance frequency in the range from 50 to 500 kHz. Serial resonance is used, the high-frequency generator is turned on inside the resonant circuit. In this device, a similar feature with the claimed invention is the use of a series resonant circuit, which is, in fact, a series oscillatory circuit. The difference is that a high frequency generator with a loop frequency connected to the loop through a matching transformer is used to excite the series resonant circuit.

The prior art has not revealed close analogues of the claimed method.

Disclosure of the invention.

An object of the invention is to develop a method for treating liquids with an alternating electromagnetic field in order to change their physical properties, to improve consumer qualities.

где:The technical result of the invention is achieved by using the device (A1) (Fig. 1) in the claimed method, consisting of a pulse generator (A2) and an oscillating circuit (A3) connected to it, the inductance (L) of which emits an alternating electromagnetic field used to process liquid media in the result of exposure to the oscillating circuit (A3) by DC pulses from the pulse generator (A2). After exposure to a direct current pulse in the oscillatory circuit, free vibrations (self-oscillations) damping in time occur at the natural frequency (Fig. 2). During these oscillations, an alternating current flows in the oscillating circuit, and self-induction EMF appears in the inductance of the oscillating circuit. As a result, the inductance of the oscillating circuit emits a time-damped alternating electromagnetic field. The decay time depends on the natural frequency of free oscillations and the loss resistance of the oscillatory circuit, which is the sum of the natural resistances of the inductance and capacitance included in the oscillatory circuit. The frequency of natural free vibrations of the oscillatory circuit depends on the values of the inductance and capacitance included in its composition and is expressed by the formula

Where:

f is the frequency of natural free vibrations of the oscillatory circuit;

π is the number π;

L is the magnitude of the inductance of the oscillatory circuit in Henry (H);

With _to - the value of the capacitance of the oscillatory circuit in farads (f). The device uses an oscillatory circuit with a natural frequency of free oscillations in the range of "50 Hz-1 GHz". The device uses both a parallel oscillatory circuit (Fig. 4), consisting of parallel-connected inductors (L) and capacitance (C) and a serial oscillatory circuit (Fig. 5), consisting of series-connected inductors (L) and capacitance (C) . In both oscillatory circuits, after the action of a direct current pulse, similar energy processes take place - a mutual energy exchange between the inductance and the capacitance decays in time. To obtain the variable electromagnetic field required for liquid processing, the oscillatory circuit (A3) is exposed to a sequence of direct current pulses from a pulse generator (A2). The higher the frequency of the sequence of direct current pulses, the greater the radiation intensity of the alternating electromagnetic field by the inductance of the oscillating circuit. The frequency of the pulse generator of the device is used in the range of "0.1 Hz - 1 MHz", the duration of the DC pulses is used in the range of "1 ns - 5 ms." To obtain the maximum radiation intensity of an alternating electromagnetic field by the inductance of the oscillating circuit, the frequency of the pulse generator is selected so that the next direct current pulse acts on the oscillating circuit until it ends with free, time-damped oscillations (Figure 3) with the natural frequency from the action of the previous direct current pulse . The duration of the DC pulses is selected sufficient for the energy supply of the particular used oscillatory circuit to receive in it free, time-damped oscillations at the natural frequency, the higher the natural frequency of the oscillatory circuit, the shorter the pulse duration. An inductance coil wound with an insulated wire or printed on a dielectric is used as the inductance (L) of the oscillating circuit (A3). To increase the inductance value, a core is introduced into the inductor wound by an insulated wire. An alternating electromagnetic field is emitted by the inductance poles (L). A capacitor is used as the capacitance (C) of the oscillation circuit (A3). The device is powered by an external DC power source, for example, 12 volts 1 amp. To influence the claimed method directly on the liquid, the inductance (L) of the oscillating circuit (A3) is immersed in them. Inductance (L), capacitance (C) of the oscillatory circuit (A3) and the pulse generator (A2) are connected by an electric circuit. If it is impossible to immerse in a liquid, the inductance (L) of the oscillating circuit (A3) by one of the poles or, depending on the shape of the core (for example "P"), by poles directed to a pipeline or a container with a liquid made of dielectric materials, is held or fixed on them, for example, with a plastic screed. To influence the claimed method on the fluids of living organisms, the inductance (L) of the oscillatory circuit (A3) by one of the poles or poles directed to the diagnosed area of the body is held on it. Inductance (L), capacitance (C) of the oscillatory circuit (A3) and pulse generator (A2) are located both in one housing and separately, connected by an electric circuit. To increase the area of liquid processing by an alternating electromagnetic field, several inductance coils are used in parallel, which form inductance (L) of the oscillatory circuit (A3).

The technical result when using the claimed method is the acquisition of fluids with increased fluidity. The conclusion about the increased fluidity of the water treated by the claimed method was made after the experiment. For the production of concrete, two identical volumetric parts of the sand-cement mixture were used, the first was closed with untreated water, the second was closed with water by the treated device used in the claimed method. To obtain the same viscosity of concrete samples of water treated by the claimed method, it took 15% less. The increased strength of a concrete sample obtained using water treated by the claimed method relative to another sample with destructive testing of samples was recorded. It took less time to solidify a concrete sample obtained using water treated by the claimed method. The conclusion about the increased fluidity of motor fuel was made after testing on a car with a gasoline engine. The initial characteristics of the vehicle’s power were recorded and recorded on a vehicle power measurement stand (dyno-stand). To process motor fuel, the device used in the claimed method was used, mounted on the fuel supply hose to the car engine. After a run of one thousand kilometers, the control characteristics of the car’s power were taken and recorded at the vehicle power measurement stand (dyno stand). When the engine was running in the range of "1500-2500" revolutions per minute, an increase in vehicle power was recorded relative to the initial readings by an average of 10%. When the engine was in the range of "2500-5000" revolutions per minute, an increase in vehicle power was recorded relative to the initial readings by an average of 5%. It was concluded that after processing the inventive method, motor fuel gained increased fluidity, as a result, it became better sprayed during the preparation of the fuel mixture and more fully burned in the combustion chamber of the internal combustion engine, increasing the power of the car. After receiving the conclusion of an accredited laboratory of Rospotrebnadzor about the safety for humans emitted by the variable electromagnetic field device used in the claimed method, it was suggested that volunteer patients try the device. After 3 sessions of using the device, by applying to the skin, 30 minutes a day, in five patients with varicose veins of the lower extremities, a decrease in edema and deformity of the veins was recorded. After 5 sessions of using the device by five patients with a diagnosis of osteochondrosis and arthrosis by applying to the skin in projection onto the inflamed vertebrae and joints, 30 minutes a day, a decrease in inflammation and improved mobility of the vertebrae and joints affected by the claimed method were recorded. It was concluded that under the influence of an alternating electromagnetic field emitted by the device used in the claimed method, due to improved blood flow, local blood circulation improves.
