Description

The invention relates to the field of operation of pipelines and vessels and is intended to destroy solid mechanical deposits of chemical compounds formed during the operation of pipelines, as well as to prevent their formation in the future, preventing chemical corrosion of the pipelines and vessels themselves.

A device for cleaning the inner surface of pipelines is known, which uses a high-frequency source of voltage induced in water, which is created by means of a transformer with a ferrite core. In this case, high-frequency voltage pulses are generated in the primary winding of the transformer, which in the secondary winding, which is composed of a hydraulic circuit, induce a voltage that diverges throughout the pipeline and even to adjacent systems. In this case, the specified device contains a housing, inside of which a ferrite core is located, and the device operates outside the pipeline. (the article was published in the magazine “Plumber” 2002, a fragment is given in the RF patent for utility model No. 154004, published on August 10, 2015).

Patent No. 154004 says:

“The disadvantage of this known device is that the electromagnetic sequential resonant frequencies generated and propagated by it do not coincide with the natural internal frequencies of the molecules of chemical substances and their compounds, which are formed as a result of the operation of the pipeline. As a result of the discrepancy between the natural internal vibration frequency of molecules and the frequency of the external electromagnetic field, the molecule does not enter into a 100% resonant vibrational process. There is insufficient “repulsion” from neighboring molecules of the substance or compound. As a result, not all solid mechanical compounds deposited on the walls of pipelines disintegrate into individual molecules. Thus, total cleaning of the pipeline is not ensured.” This drawback was formulated by the leading author indicated in patent No. 154004, and now a participant in the development and testing of the method and devices that are the subject of the present inventions.

A ferromagnetic high-frequency device for cleaning and protecting the internal surface of pipelines is known, containing a housing with a ring ferrite core located in it, a power supply unit connected to the housing, and a high-frequency generator unit, characterized in that the ferrite core is made of the MnZn class with a frequency range of up to 500 KHz (patent for utility model No. 154004, prior. 09.29.2014, pub. 08.10.2015, IPC B08B 9/027 (2006.01).

The device uses a microprocessor.

The device is installed in water supply, heat exchange, heating, water treatment systems for cottages, retail establishments, offices, etc. The described technical solution for utility model patent No. 154004, based on the totality of essential features, is accepted as a prototype.

Based on the importance of the technical problem being solved by the prototype, a fairly detailed description of it is given below. As described in the patent for utility model No. 154004, “the task and technical result that the utility model is aimed at is the total cleaning of the pipeline from solid mechanical connections, due to the creation of an electromagnetic field by the device. The implementation of the technical result is carried out due to the operating principle of the device, which is based on the generation and propagation in the liquid of electromagnetic sequences of resonant frequencies that coincide with the natural internal frequencies of the molecules of chemical substances and their compounds, which are formed as a result of the operation of the pipeline. As a result of the coincidence of the natural internal vibration frequency of molecules with the frequency of the external electromagnetic field, the molecule enters into a resonant oscillatory process. At the same time, it strives to “push off” as far as possible from neighboring molecules of a substance or compound. As a result, all solid mechanical compounds deposited on the walls of pipelines disintegrate into individual molecules, saturating the liquid. They can later be removed from the working system using filters. This ensures total cleaning of the pipeline.”

The device according to patent No. 154004 consists of:

“- from a high-frequency generator block made in the form of a printed fiberglass electronic board with double-sided electronic elements mounted on it and an output winding in the form of a cable loop, a power connector, as well as connectors for connecting power;

- ferrite ring core;

- device housing (to accommodate the electronic board of the high-frequency generator, ferrite ring core, power connector and indicators);

- power supply.

In this case, the high-frequency generator block is a cascade generator circuit that generates electrical pulses of a given amplitude, duration, power and frequency. In this case, the generator is controlled by a programmable microprocessor. The program is designed in such a way as to create a sequence of resonant frequencies that coincide with the natural frequencies of the molecules of chemical elements and their compounds (mainly salts) present in aqueous solutions, as well as on the internal walls of devices in the form of solid deposits (precipitations).

The internal electrode of the power input connector must have a positive polarity of “+” 12 Volts.

In this case, the operating frequency range set by software, depending on the specific chemical analysis of the composition of the working fluid, ranges from 0.5 to 20 KHz.

Thus, the device according to patent No. 154004 makes it possible to generate and propagate in a liquid electromagnetic sequences of resonant frequencies that coincide with the natural internal frequencies of the molecules of chemical substances and their compounds, which are formed as a result of the operation of the pipeline.”

Working with the device according to patent No. 154004 revealed the following shortcomings:

- the microprocessor does not recognize the coincidence of resonant frequencies due to the lack of feedback and does not increase the exposure time when they coincide;

- time to dissolve and prevent deposits increases;

- to generate and propagate electromagnetic sequences in a liquid that coincide with the natural internal frequencies of the molecules of chemical substances and their compounds, it was necessary to know their chemical and quantitative composition in advance, i.e. carry out appropriate preliminary laboratory analysis of deposits inside the pipe(s). This problem is significant;

- the time of exposure to frequencies, as well as the time of “idle” periods when the frequencies do not coincide, are the same for all chemical compounds, which increases the total exposure time of the device.

In addition, in the embodiment of the device, in which the ferrite core is solid, during installation it requires disconnecting the pipeline, which increases the complexity of cleaning the pipeline.

These disadvantages of the prototype are eliminated by the claimed invention.

The technical result consists in developing a method for internal cleaning of pipes from deposits with achieving 100% resonance of the frequencies generated by the device with the frequencies of molecules of chemical substances and compounds without extraction and laboratory analysis of these substances and compounds, which significantly increases the cleaning efficiency, and also reduces time, labor intensity and cost performing cleaning work.

The technical result is achieved by developing a method for cleaning and protecting the internal surface of a pipeline, which consists of exposure to an electromagnetic field, characterized by the fact that the influence is carried out through adaptive (self-adjusting) cyclic generation of sequences of resonant electromagnetic high-frequency fields coinciding with the internal frequencies of natural oscillations of chemical elements and their compounds present in a conductive medium based on aqueous solutions, while adaptive generation prevents the formation of deposits on the internal surfaces of pipelines and containers and at the same time ensures the dissolution of already formed deposits, without requiring a preliminary analysis of the content of chemicals and their compounds in the solution.

An adaptive system (self-adapting system) is a system that automatically changes the data of its functioning algorithm and (sometimes) its structure in order to maintain or achieve an optimal state when external conditions change (Wikipedia).

In addition, the method is characterized by the fact that adaptive generation is carried out using a microprocessor and software, while the microprocessor sets the generator frequency in the range from 5 to 20 kHz with a step of 0.5 kHz per cycle, i.e. initial 5.0, then 5.5, then 6.0, 6.5, 7.0, 7.5 KHz, etc.; having reached a value of 20 KHz, the program again returns to generating an initial frequency of 5.0 KHz; then the cycle repeats; The duration (time) of generation of a specific fixed frequency is also determined by the program embedded in the microprocessor.

Water-based conductive liquids used in pipelines and vessels for various purposes contain dissolved salts of alkaline earth chemical elements and their compounds, mainly calcium, magnesium, iron, etc. During operation of pipelines and vessels, these salts are deposited in the form of solid substances on the internal surfaces of these devices, reducing the flow sections of pipelines and reducing heat exchange between the elements of internal devices (for example, heating elements), they impede the operation of the mechanical elements of shut-off and control valves (for example, ball valves, gate valves).

Each chemical element and their compounds (salts), which are dissolved in a conductive medium, have an internal frequency of natural vibrations, called the resonant frequency.

Each molecule of salts consists of atomic nuclei around which internal electrons and external valence electrons rotate in orbits. The frequency of rotation of electrons in an equilibrium state is the internal natural frequency of vibrations (each compound has its own); in a state of rest, the electric charge of molecules is zero. When a molecule is placed in an external alternating electromagnetic field, if the frequency of the field coincides with the internal natural frequency of rotation of the electrons, the latter move to higher orbits with an increase in energy potential. Due to this, the molecule itself acquires an electrical charge different from zero. The transmission of electromagnetic field pulses to electrons occurs through a conductive medium in which salts are present.

All molecules of a particular compound acquire the same electrical charge. Likely charged molecules repel each other. Thus, layer-by-layer “dissolution” of deposited salts occurs at the molecular level. and also the acquired electric charge does not allow the molecules to get closer to each other (as if to “stick together”), turning into a solid substance with further settling (deposition) on the inner walls of pipelines and vessels.

Thus, the method is implemented by using the generation of an electromagnetic field of variable frequency with measuring its strength, controlling the value of the radiation frequency and the duration of generation of a specific frequency, as well as the cyclicity of processes using a microprocessor program.

An additional winding is mounted on the emitter, which performs the functions of a sensor for measuring the electromagnetic field strength. When the frequency of the external electromagnetic field coincides with the own internal (resonant) frequency of any chemical compound present in a conductive solution, the strength of the external electromagnetic field decreases, since part of the energy is spent on the formation of a charge on the molecules of the compound. At each step of changing the frequency of the generator, the control processor compares the strength of the external electromagnetic field with the strength of the idle (base) field (i.e., when the frequency of the external field does not resonate with the internal natural frequency of any chemical compound). When the voltage drops, the processor programmatically increases the time (duration) of exposure at a specific resonant frequency several times (from 3 to 8).

Thus, there is no need for a preliminary chemical analysis of the composition of compounds in a conductive solution. The electronic device itself “finds” resonant frequencies, adapting to the chemical composition of the compounds in the solution.

Thus, the entire range of frequencies coinciding with the internal natural frequencies of salts in aqueous solutions is covered. The effect of frequency resonance occurs, which leads to the appearance of electric charges of the molecules of the same name. With each cycle the magnitude of the charges increases. Salt molecules tend to occupy an equilibrium (stable) energy position in an aqueous solution. Solid deposits of salts decompose into individual molecules, the concentration of which in aqueous solutions increases. In flowing water systems, molecules of dissolved deposits are carried away along with the flow; in closed systems, a conductive liquid with a high volume concentration of salts is replaced with fresh one.

The claimed invention is a method for cleaning pipes and vessels by adaptively cyclically generating sequences of resonant electromagnetic high-frequency fields that coincide with the internal natural frequencies of chemical elements and their compounds present in a conductive medium based on aqueous solutions.

The method is an advanced complex modern development, in demand in various fields of science, technology, industry, in everyday life and when conducting relevant experiments - in medicine.

The method was developed with the direct participation of the author of the device under RF patent No. 154004.
