Description

Technical Field

[0001] The invention relates to the technical field of descaling and antiscaling equipment for water-using devices, and in particular to a high-frequency electronic descaling and antiscaling system. Background Art

[0002] Circulating water system is an indispensable equipment for large-scale equipment to exchange heat. It is widely used in industrial production and daily life, such as electricity, petroleum, steel, chemical industry, mining and other industries. The scaling problem of circulating water system heat exchange equipment has always plagued these industries. In actual life and engineering fields, more than 90% of heat exchange equipment has different degrees of scaling problems. The common main components of scale are calcium carbonate, silicate, sulfate and their mixtures. Their thermal conductivity is generally 0.05-0.7cal / m·h·℃, while the thermal conductivity of metal steel pipes is 70-1000 times that of steel pipes. The smaller the thermal conductivity, the more difficult the heat transfer is. Therefore, more energy is needed to achieve the expected heat exchange effect.

[0003] According to statistics provided by the North American Economic Feasibility Conference, the annual industrial losses caused by fouling in the world amount to 0.3% of the total industrial output value. In my country, the industrial losses caused by fouling are much greater than 0.3%. In addition, the annual power loss caused by scaling problems in cooling towers in power plants in the United States alone amounts to 1.85GW.h, while in my country, tens of thousands of heat exchangers are scrapped every year due to corrosion and scaling, with an estimated direct economic loss of 200 million yuan per year.

[0004] At present, the commonly used anti-scaling and descaling methods are to put various drugs in the water. At the same time, the drugs put in need of regular replacement and replenishment. Severe scaling also requires acid washing and other means. Therefore, chemical methods are prone to secondary pollution of the environment, and acid washing requires interruption of system operation, affecting normal production. Scale will form a concentration cell on the attachment surface of the metal equipment, and different temperatures will appear on different parts of the surface of the heat exchanger. The concentration cell will cause under-scale corrosion, and different temperatures will cause local corrosion of the metal equipment.

[0036] The following will refer to Figures 1 to 5 , the working principle of the present invention is explained.

[0037] The present invention can efficiently destroy the hydrogen bonds between water molecule clusters, change the polarization characteristics of water molecules, form small molecule clusters or monomer water molecules, and form a wrapping effect on scale-causing ions, that is, change the structure of calcium and magnesium components in water, so that they lose the scaling ability in cooling water equipment and pipelines, and achieve the effect of scale inhibition and descaling; prevent the formation of crystal nuclei, efficiently penetrate into the interior of the scale layer, and disintegrate the original scale layer under the local vaporization and expansion of the heat exchange wall; the electromagnetic field and polarized water molecules form peroxide vacuoles in the bacteria, destroy and inactivate the bacteria by destroying dismutase and other effects, and play a role in sterilization, algae removal, and prevention of biological slime. Based on the above principles, the circulating cooling system can be safely operated at a higher concentration multiple, effectively reducing the demand for new water replacement, and achieving a significant increase in water saving rate and production line energy efficiency.

[0038] When water passes through a high-frequency electric field, the water molecules absorb electromagnetic energy and become activated, and their structure changes, which are mainly manifested in two aspects: a) Water molecules have strong polarity. In the H2O molecule, the three atomic nuclei are arranged in an isosceles triangle with the hydrogen nucleus as the bottom and the oxygen nucleus as the top. The O-H bond distance is 0.0978nm, the H-H distance is 0.154nm, and the bond angle between H-O-H is 104.12°. The OH in the water molecule is a covalent bond. Since the electronegativity of hydrogen is smaller than that of oxygen, their shared electron pairs are biased to a large extent toward the oxygen nucleus, making the hydrogen nucleus almost "exposed". The S electron cloud of the hydrogen atom in the water molecule overlaps with the P electron cloud of the oxygen atom to form a unified electron cloud of the entire water molecule, which is shaped like a half-twisted cross. The density of the electron cloud is mainly concentrated near the oxygen nucleus, so that a large number of electrons near the oxygen nucleus completely shield the positive charge of the nucleus, and the two pairs of electrons present two negatively charged poles. Near the hydrogen nucleus, the electron density is small and cannot completely shield the positive charge of the nucleus. The four poles are exposed to form two positively charged poles. These four poles are not on the same plane, and their relative positions are similar to a wedge-shaped tetrahedron, thus forming a polar molecule with one end positively charged and the other end negatively charged; the dipole moment of the water molecule is very large, p = 1.84D (1D = 3.336*10-30C.m), so the polarity is very strong. There are strong hydrogen bonds between water molecules. Each water molecule can generate 4 hydrogen bonds, which are connected to the 4 closest water molecules. The combination and breaking of hydrogen bonds in water are completed instantly, which is called "flickering clusters". In liquid water, water molecules exist in a state of coexistence of single water molecules and aggregates of water molecules. In the X-ray diffraction measurement of water, it was found that the aggregate of water molecules is a whole composed of several single water molecules connected by hydrogen bonds, in the form of chains or rings. Since hydrogen bonds are weak, only a small amount of energy is needed to destroy them, and the spatial conditions for hydrogen bond formation are more likely to occur, so hydrogen bonds between molecules and within molecules can be continuously formed and broken, resulting in the simultaneous association and dissociation of water molecules at room temperature, namely:

[0039] (H2O) n →xH2O+(H2O) n-x

[0040] On the one hand, some hydrogen bonds in the associated water molecule groups are broken, so that some water molecules leave the associated groups and become small water molecules; on the other hand, some water molecules combine to form new hydrogen bonds. Therefore, as long as the energy required for this dynamic balance is provided, the water molecule groups can decompose or associate.

[0041] The formation of scale must go through three stages: crystal nucleation, crystal growth and crystal aggregation. Therefore, anti-scaling measures can also be considered from these three stages of crystal growth. According to crystallography, there are five main factors that affect crystal growth: crystallization rate, temperature, impurities, environmental heterogeneity and solution pH (pH value).

[0042] ①Crystallization speed

[0043] When the crystallization speed is high, the crystal centers increase, the crystals grow thin and small, and often grow into needles or dendrites. On the contrary, when the crystallization speed is low, the crystals grow extremely large.

[0044] ② Temperature

[0045] Changes in temperature will lead to changes in supersaturation or supercooling, which will change the surface of the crystal face and the relative growth rate of different crystal faces, thus affecting the crystal morphology. For example, calcite is flat when it is formed at a higher temperature, but it is often slender bamboo shoots when it is formed in surface water solution.

[0046] ③Impurities

[0047] Impurities affect the crystal morphology by changing the surface energy of different crystal faces. For example, table salt in pure water without impurities is a cube, but when a small amount of boric acid is present in the solution, a mixture of cubes and octahedrons will appear.

[0048] ④ Environmental heterogeneity

[0049] Theoretically, if the crystal growth environment (temperature, supersaturation of the solution) is uniform, the growth rate of surfaces with the same properties should also be the same. However, in reality, the crystal growth environment is not uniform. Around the growing crystal, the solution adheres to the crystal, its own concentration decreases, and the heat is released or absorbed during crystal growth, which reduces the specific gravity of the solution. Due to the effect of gravity, the light solution rises, and the surrounding heavy solution is replenished, thus forming a vortex. The vortex is upward when the crystal grows, and the opposite is true when it dissolves. The vortex makes the solution material supply uneven and directional, thus making the morphological characteristics at different positions different.

[0050] ⑤ pH

[0051] Lowering the pH value of the solution can reduce the scaling tendency of CaCO3 and MgCO3 (mainly CaCO3), because Ca(HCO3)2 and CaCO3 have the following reaction equations in the solution:

[0052]

[0053] A decrease in the pH value of the solution will increase the H+ concentration, causing the reaction of equation (2.5) to proceed to the left, increasing the HCO3- concentration and reducing the Ca2+ concentration, thereby causing the reactions of equations (2.4) and (2.6) to proceed to the left, and ultimately converting the CaCO3 precipitate into a water-soluble Ca(HCO3)2 solution, thereby inhibiting the formation of scale. Conversely, if the pH value of the solution increases, the H+ concentration in the solution decreases, causing the reaction of equation (2.5) to proceed to the right, ultimately causing the reactions of equations (2.4) and (2.6) to proceed to the right, causing Ca(HCO3)2 to be converted into CaCO3 precipitate. The electromagnetic field scale inhibition and descaling theory is inseparable from the scale formation mechanism, so it is of great significance to carefully explore the various parameters of scale formation, including nucleus formation, crystal growth and crystal aggregation stages.

[0054] When using the present invention, according to the size of the water pipe, a plurality of connecting blocks 21 are used to form a conduction ring 2, and then the conduction ring 2 is fixed on the surface of the water pipe, so that the main body 1 is closely attached to the surface of the water pipe, and then a cable tie is tied to the surface of the water pipe to further fix the main body 1 on the water pipe. The communication module 13 can be remotely controlled, that is, remote operation can be performed through a computer, a mobile phone APP, etc. The monitoring module 14 can monitor the change of water quality in real time, and then the emission control module 11 and the electromagnetic conduction module 12 are used in conjunction to emit high-frequency electromagnetic waves to the water in the water pipe. The emitted high-frequency electromagnetic waves have a stronger water molecule cluster cracking effect for different water qualities, produce more small water molecule clusters or monomer water molecules, enhance the penetration effect, and are easier to penetrate into the scale layer near the high-temperature heat exchange wall. , the movement of water molecules is strengthened by heat, resulting in local vaporization and expansion, which disintegrates and loosens the scale, and gradually falls off under the impact of water flow, thus effectively removing the original scale layer; at the same time, high-frequency electromagnetic waves cause additional magnetic moments, additional energy and additional electric fields in the aqueous solution, which reduces the cohesion of the aqueous solution and lowers the molecular potential barrier. Experimental analysis found that the microcrystalline molecular structure of the water precipitated after electromagnetic wave treatment is loose, and the calcium carbonate of this lattice is not easy to adhere to the pipe wall, but floats in the water, playing a role in scale inhibition; and the water cannot form a primary battery reaction through the action of high-frequency electric waves, which destroys the environment for the growth of the original germ and inhibits the growth of microorganisms. High-frequency electric waves also have the ability to peroxidize the biofilm and destroy dismutase, thereby playing a sterilization and algae removal effect in the process.

[0055] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art who is familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
