Description

SCALE CREATION AND CORROSION PREVENTION APPARATUS FOR PIPE LAYING

The present invention relates to scale generation and corrosion prevention apparatuses for pipes to prevent corrosion and corrosion generated in pipes through which hot and cold water flows, and more particularly, to scale generation and corrosion prevention apparatuses for pipes using electromagnetic field treatment. .

In general, circulating oil systems such as water heaters, boilers, and heat exchangers using fresh water will generate scale and corrosion.

For example, when the temperature is high, such as boiler water, the reaction between water and iron is made as shown in Figure 1 to produce iron trioxide (Fe ₂ O ₄ ). In the heat transfer surface, when the acidity is appropriate, iron tetraoxide is formed on the heat transfer surface to form an anticorrosive film. When dissolved oxygen is present, corrosion easily proceeds, and as shown in FIG. 1, a corrosion reaction is performed in which a battery is locally formed. This is represented by the following Scheme 1 and Scheme 2.

+ 4e 2Fe → 2Fe ^{++ -:} anode unit

Catho Wood Department: _{O 2 + 2H 2 O + 4e} - → 4OH -

Corrosion reaction: _{2Fe + O 2 + 2H 2 O} + 4e - → 2Fe ++ + 4OH - → 2Fe (OH) 2

In particular, when the oxide protective film is partially destroyed on the heat transfer surface, corrosion products are deposited on the portion. The oxygen concentration of sediments and water causes a difference in the oxygen concentration cell, and the iron surface becomes the anode, and the elution of iron continues to cause corrosion.

Chlorine ions are representative of harmful ions that promote corrosion and have a property of destroying a protective film.

Therefore, when the dissolved oxygen is high, when the acidity (PH) is not appropriate, and when the harmful dilute concentration is high, corrosion occurs quickly.

In addition, circulating oil systems such as water heaters, boilers, heat exchangers, etc., which use fresh water, generate scale due to inorganic deposits and deposit in the pipes. It may be destroyed. Freshwater usually contains relatively large amounts of inorganic matter that separates from the fluid to form crystalline compounds. Most of these minerals have incompatible curves, which are especially produced in high temperature circulation systems, resulting in severe scale deposition. Inorganic minerals that cause economic losses due to scale deposition are mainly calcium, magnesium, silica, potassium, and magnesium carbide.

Scale formation proceeds by the deposition of crystals around atypical micronuclei when ions in the fluid's components are arranged inside an excited state compound with a constant geometric phenomenon. The result is a crystal in the form of a saturated bond. If an atomic group forms a resin structure or a unit structure having a repeating three-dimensional shape, scale is formed on an interface in contact with water. The binding force attached to the product is the static electricity between ions. Chemical and electrical devices that prevent the formation of such a matrix of crystals have not been successful despite the fact that minerals do not have a crystal structure in water.

Conventionally proposed methods to solve the scale problem are classified into two types, chemical and electrical methods.

Chemical methods have long been used to prevent scale of water treatment systems, and certain chemicals, such as phosphoric acid or polymers of natural or artificial organics, can change charges to prevent the formation of crystal structures.

However, chemical treatment causes environmental pollution in water treatment systems due to the pollution of the environment by chemicals.

Electrical devices for scale prevention of water treatment systems fall into the electrostatic, electromagnetic, electrophoretic and electromagnetic fields. All of these devices are intended to prevent the crystal structure of inorganic materials by using electrical.

The conventional electrostatic water treatment apparatus forms an electrostatic field by bridging the anode and the cathode while applying a high voltage through water and the electrodes insulated from each other. However, conventional electrostatic water treatment devices have to increase the size of the anode and cathode in order to increase the magnetostatic force, which requires a higher voltage. As a result, an insulation gap is required to protect the electrode from water, and thus there is a problem of being limited by the insulation threshold thickness due to insulation.

In addition, the conventional electromagnetic water treatment apparatus uses a permanent magnet or an electromagnet to obtain a result such as an electrostatic field.

In addition, the conventional electrophoretic water treatment apparatus uses a different type of metal having a large difference in electronegativity to achieve the action of electrons attracting molecules to electrodes of reverse potential.

In addition, in the conventional electronic water treatment device, an electric field is applied between electrodes having reverse potential by using a DC low voltage power source. The electrodes are insulated from each other, but not from the fluid itself.

However, the conventional water treatment apparatus described above has a problem in that assembly and disassembly are difficult and operation and maintenance are difficult.

In order to solve the above problems, the present invention provides a scale generation and corrosion prevention apparatus for maximizing generation of electrons by using an electromagnetic field treatment method to prevent scale generation and corrosion while facilitating assembly and disassembly in piping using cold / hot water. Has its purpose.

In order to achieve the above object, the present invention provides a signal for forming an electromagnetic field so that the irregular inorganic material in the fluid has a regular structure in order to prevent scale generation and corrosion of the pipe by the inorganic material contained in the fluid flowing in the pipe. The inlet and outlet are provided so that the fluid flows in and out between the signal generating means, the electrode rod in which the positive electrode is formed to form an electromagnetic field in the fluid according to the signal output from the signal generating means, and the electrode. The negative electrode is formed by the electrode to form an electromagnetic field between the electrode and the inorganic material in the fluid is changed into a regular structure to induce a large amount of free electrons in the fluid to prevent scale generation and corrosion of the pipe. Provides scale generation and corrosion protection of pipes, including pipes The.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The scale generation and corrosion prevention apparatus of the piping by this invention consists of a signal generation part 1, the electrode rod 3, and the induction pipe 2, as shown in FIG.

The signal generator 1 generates a signal for forming an electromagnetic field so that the irregular inorganic material in the fluid has a regular structure in order to prevent scale generation and corrosion of the pipe by the inorganic material contained in the fluid flowing in the pipe. As shown in FIG. 4, the power supply unit 11 for supplying AC power, the transformer 12 for converting the voltage of the power supplied from the power supply unit 11, and the voltage converted in the transformer 12. DC converter 13 for rectifying and converting AC power into DC, and a frequency signal generator 14 for generating a signal having a specific frequency as an output of the DC converter 13.

Here, the signal generated by the signal generator 1 is a signal having a current magnitude of 1 mA to 100 mA or less and a voltage magnitude of 1 V to 500 V so that an electromagnetic field is formed between the electrode 3 and the induction pipe 2.

The electrode 3 is a positive electrode is formed to form an electromagnetic field in the fluid in accordance with the signal output from the signal generator 1, made of a titanium material, made of a cylindrical shape.

The induction pipe (2) is provided with the inlet and outlet (4, 5) so that fluid flows in and flows between the electrode (3) and the negative electrode is formed by the electrode (3) to the electrode (7) An electromagnetic field is formed between and the inorganic material in the fluid is changed into a regular structure so that many free electrons are contained in the fluid to prevent scale generation and corrosion of the pipe. The cylindrical shape is made to maintain a constant distance from the electrode 3 in order to make the density uniform.

Here, the inlets and outlets 4 and 5 are installed in the form of a bridge in the pipe so that the fluid in the pipe flows into the induction pipe 2.

The operation | movement of the scale generation and corrosion prevention apparatus of the piping by this invention comprised in this way is demonstrated.

First, as shown in FIG. 3, inlet and outlet ports 4 and 5 attached to the induction pipe 2 are installed in a bridge form in a portion of the pipe 6 in order to install the scale generating and corrosion prevention device in the pipe.

When the installation is completed, as shown in FIG. 3, the fluid 7 flowing in the pipe 6 is introduced into the induction pipe through the inlets and outlets 4 and 5 of the induction pipe 2.

At this time, when power is applied to the signal generator 1, the electrode 3 becomes a positive electrode. That is, as shown in FIG. 4, when power is supplied from the power supply unit 11, the transformer 12 changes the voltage to a desired voltage, and the DC converter 13 converts the DC signal into DC. This generates a signal for forming an electromagnetic field.

That is, the frequency signal generator 14 generates a signal having a current magnitude of 100 mA or less and a voltage magnitude of 500 V or less so that an electromagnetic field is formed between the electrode 3 and the induction pipe 2 to allow the electrode 3 and the induction pipe ( 2) Make the inorganic material contained in the fluid between them have a regular structure.

In other words, the signal output from the signal generator 14 is applied to the electrode 3 so that the electrode 3 has a positive polarity. As a result, the induction tube 2 has a negative polarity, and an induction current flows through the fluid 7 between the electrode rod 3 and the induction tube 2. This induced current causes the inorganic matter contained in the fluid to have a regular structure, which causes more free electrons.

As such, the fluid containing a lot of free electrons is discharged to the pipe through the inlet and outlet 4 and 5 again, so that the inorganic material does not absorb the electrons in the pipe, thereby preventing the pipe from corroding or changing the inorganic material to scale.

As described above, an electromagnetic field is formed between the electrode rod 3 and the induction pipe 2 to change the characteristics of the fluid in the pipe 6.

Since the electrons in the fluid 7 in the ground state are in a low energy state as shown in FIG. 5A, the electrostatic forces of the ions 8 and the charged particles 9 are strong and have an irregular arrangement. The scale 10 is produced by concentrating on the surface of 6).

In addition, when the electrons in the fluid 7 in the ground state are converted into a high energy state by the weak current generated in the electrode 3, the ions 8 in the fluid as shown in FIG. The electrostatic attraction of the charged particles 9 is weakened so that formation of scale is suppressed and the generated scale is removed.

That is, an electric field is formed between the electrode 3 and the induction tube 2 by the weak current generated in the electrode 3, and thus the electrons in the fluid 7 are converted into a state of high energy level. As the energy level of the fluid rises, the electrostatic attraction of the ions 8 and the charged particles 9 dissolved in the fluid is eliminated and dispersed, resulting in a regular arrangement. Accordingly, the free electrons are abundant in the fluid 7, and the free electron-rich fluid 7 flows into the pipe to prevent oxidation of the pipe to suppress corrosion, and the inorganic material 9 contained in the fluid 7 Regular arrays will suppress scale generation.

On the other hand, since the induction pipe (2) is formed in a cylindrical shape to have the same distance between the electrode (3), the distance between the (+) pole of the electrode (3) and the (-) pole of the induction pipe (2) is constant The density of the electromagnetic field inside the induction tube 2 becomes uniform. As a result, the fluid undergoes uniform treatment as it proceeds, thus completely eliminating the electrostatic properties of the inorganic material.

As described above, since the scale generation and corrosion prevention apparatus of the pipe according to the present invention is installed in the bridge form in the pipe, it is easy to assemble and dismantle, and the effect of preventing scale generation and corrosion by completely eliminating the electrostatic properties of the inorganic material. There is.
