The voltaic battery of the present invention is installed in the pipe housing and the cathode tube having a predetermined size space therein, a ring-shaped high purity ceramic member arranged in the center axis direction inside the cathode tube, a ring core around the zinc alloy As a result, a plurality of unit battery cells in which a silver alloy coil and an aluminum coil are wound are repeatedly arranged adjacent to each other.

Hereinafter, a basic principle related to water treatment will be described to help understanding the water treatment apparatus of the present invention.

Typically, when the electrochemical reaction is a kinetic to the node (Anode) to the basic polar electrolytic H ⁺ ions increases with the density of the reduction decomposition of H ₂ O than the reduction of the H ⁺ ion been followed H ⁺ and OH ^- Ions are produced.

That is, H ₂ 0 + 2e ^- causing a reaction of the ^- → H ^{+ +} 2OH.

As described above, when the reduction reaction occurs, the concentration of hydrogen ions H ⁺ is increased, thereby increasing the pH at the cathode surface, and ORP (redox potential) is negatively polarized.

In the Stability Field Water, when water is used as an oxidant, water is reduced to H ₂ , and when used as a reducing agent, water is oxidized to O ₂ .

Molecules that can withstand water must have a reduction potential between the limits corresponding to the above two processes. In addition, the water to be reduced is rapidly reduced to H ₂ and the oxidant is rapidly oxidized to O ₂ so that it does not exist in the liquid state (see FIG. 2).

On the other hand, the important factor to rust iron is the air and moisture in the air, so the water redox reaction occurs on the iron surface occurs. OH ⁻ generated at the (+) electrode is combined with Fe ²⁺ on the iron surface to form Fe (OH) ₂ , and Fe (OH) ₂ is combined with air to form Fe (OH) ₃ . Fe (OH) ₃ becomes Fe ₂ O ₃ and X ₂ H ₂ in red, which is dissolved in Fe ₂ O ₃ .

Fe + H ₂ O → O ₂

_{^{Fe (OH -) + H 2}} O → Fe 2 O 3 ( corrosion)

Therefore, in order to protect the surface of iron in contact with water, the present invention uses a ball-tick cell and far-infrared rays to melt the metal surface by anodizing it to pH 8-10, ORP (-400-)-(-800mv). Do not occur.

Fe ₂ 0 ₃ → Fe ₃ O ₄

The formation of rust means that impurities are confined to the metal surface in contact with water, and when the rust formation reaction is largely divided, it is considered to be an ionic bond due to the difference in electrical polarity between the metal surface of silicic acid, carbonic acid, and sulfuric acid. can do. For example, the bonding process with bicarbonate 2 (HCO ₃ ⁻ ) present in water causes the ion groups to bind or dissolve depending on the carbon dioxide concentration.

^{_{2 (HCO 3 -) + Ca}} ++ → CaCO 3 ↓ + H 2 O + CO 2 ↑

FIG. 3 is a graph showing the activation state of water, and is a graph showing the change in concentration of CO ₂ according to the total hardness of water (THD).

When water is activated (recombination of the two molecules is repeated), the condition of θ1 (dissolution) in the graph shown in FIG. 3 becomes, and the metal surface is (+) and the scale ion (- Easily adheres to ions.

Generally, the water used is pH 7, ORP is 150㎷ ~ 300mv, total hardness (THD) is 80ppm (water supply), TDS (dissolved solids) is 150ppm, and the polarity of metal surface is (+) to (-). The conversion to facilitates the prevention of adhesion. These potentials are required to make polarized eastern arcs while the water used by different ions passes through the water treatment system.

Looking at the process of self-voltage generation of the voltaic battery, as shown below (-400mv) ~ (+ 800mv) and generates a total voltage of 150mv to amplify a constant electric field in the capacitance of the ion causing the scale phenomenon in the drain pipe Induce adhesion to offset, prevent rust and scale formation or remove rust and scale produced.

Negative electrode: Zn → Zn ²⁺ + 2e ^- EO oxidation = (-) 400㎷ ~ (-) 800mv

Positive ^{electrode: Cu 2+ + 2e - → Cu} EO reduction = (+) 400㎷ ~ (+) 650mv

(All): Zn + Cu ²⁺ → Zn ²⁺ + Cu EO Total = 150mv

The generation of scale means that impurities are confined on the metal surface in contact with the water, which means that the inorganic and salt components dissolved in the water exist as negative ions, and then the electrical polarity of the cation on the pipe (metal) surface. It means that the crystals are formed on the wall of the pipe by combining by the difference.

2 (HCO ₃ ⁻ ) + Ca ⁺⁺ (or any one of Mg ⁺⁺ , Na ⁺⁺ , SiO ₂ ) →

CaCO ₃ ↓ + H ₂ O + CO ₂ ↑

On the other hand, the ORP of water reaches up to -800mv by the electrochemical reaction by the voltaic battery provided in the apparatus of the present invention and the far-infrared wavelength emitted from the ceramic member, so that bactericidal and suppression of production and odor removal are performed.

However, microorganisms are killed by a potential difference of only a few mv, so they have a sterilizing function to kill microorganisms, thereby preventing the occurrence of bacteria. In addition, components such as ammonia (NH ₃ ), ammonia nitrogen, hydrogen sulfide (H ₂ S), and nitrate nitrogen are suppressed and sublimed (vaporize) to remove odors.

Hereinafter, a preferred embodiment of the water treatment apparatus according to the present invention will be described in detail with reference to the accompanying drawings.

Figure 4a is a front sectional view of the water treatment device according to the present invention,

4B is a cross-sectional view taken along line B-B of FIGS. 4A and 4B;

Figure 4c is an exploded perspective view showing the internal components separated to show the internal components of the water treatment apparatus according to the present invention.

Referring to the drawings together, the water treatment device 50 of the present invention is formed with flanges 15 connected to any pipe at both ends, respectively, the inlet of the water so that water is introduced from one end to the other end is discharged A pipe-like piping housing 5 in which 7 and outlet 8 are formed, respectively; A voltaic battery 40 formed with a ceramic in the pipe housing 5 so as to achieve bacterial sterilization, odor removal and scale generation of water introduced through electrical action of the battery and far-infrared radiation of the ceramic; The voltaic battery 40 is largely composed of a voltaic battery support 14 which is fixed to the piping housing 5 by fixing.

The pipe housing 5 is a pipe-type pipe of iron or non-ferrous material, the voltaic battery 40 of the present invention is installed inside the pipe housing 5, the cathode tube (3) having a predetermined size space therein And a silver alloy coil 2 and an aluminum coil 11 wound around a ring-shaped high purity ceramic member 4 and a zinc core ring core 1 installed in the center axis direction of the cathode tube 3. The unit battery cells 18 have a structure in which a plurality of unit batteries are sequentially arranged adjacently. In this structure, the ceramic member 4 is repeatedly arranged adjacent to the unit battery cell 18. In particular, the ceramic member 4 is positioned at positions of both ends as well as the inside, so that the unit battery cell 18 is internal. Ensure a stable structure located in. A separate fixing member 12 is installed around the top and bottom of the unit battery cell 18 to separate the unit battery cell 18 and the adjacent ceramic member 4 so as not to make direct contact with each other to obtain an insulation effect. In addition, to facilitate the installation inside the cathode tube (3). That is, the unit battery cell 18 is disposed inside the cathode tube 3 in the direction of the central axis thereof, and then the cathode tube 3 and the unit battery cell are fixed by using the binding means 13, for example, a fixing bolt, to maintain a solid binding state. Bond between the fixing members (12).

On the other hand, the auxiliary auxiliary fixing member 12a is also attached to the upper and lower circumferences of the high purity ceramic member 4 positioned at the outermost side of the voltaic battery 40 to facilitate the fixing of the ceramic member 4. That is, the auxiliary fixing member 12a is installed at a portion of the ceramic member 4 located at the outermost sides of the voltaic battery 40 and in contact with the cathode tube 3 at the lower end thereof. 5) is connected.

On the other hand, each of the unit battery cells 18, the power line (not shown) is drawn from the upper and lower ends thereof to be electrically connected to the cathode tube (3).

In addition, a lower portion 6 of one side of the pipe housing 5 is provided with a drain 6 for discharging the sediment produced through the water treatment process.

The high-purity ceramic member 4 installed in the vicinity of the unit battery cell 18 activates the water to promote the self-cleaning ability of the water and maintains a weak alkali state to form hexagonal water to make very stable water. Water with hexagonal water structure has fast absorption rate in the body and helps to promote the production of cells, which greatly helps to maintain the health of the human body. In addition, weak alkaline water is fast to absorb the plant, the invasion of pathogens is very difficult compared to the general water and sterilize bacteria, so the growth of the plant is fast and fruity, and has strong characteristics against pests.

The water treatment apparatus according to the present invention configured as described above is simpler to install and separate its components than the conventional apparatus exemplified above, and to increase the manufacturing process efficiency and reduce the cost by simplifying and miniaturizing the structure of the apparatus. Can be.

In addition, it has a ring-like structure so that the flow of water flows constantly around the battery cell has a certain advantage that the contact between the battery cell and water.

Hereinafter, the operation of the water treatment apparatus of the present invention will be described.

First, the water treatment apparatus of the present invention performs a function of preventing rusting in the pipe and removing scale through the functional position adjustment of water.

FIG. 2 is a diagram showing a Perlbeek diagram, in which a thermodynamically stable area is expressed as a reduction potential or a pH value when water is oxidized and reduced, and a functional position of water is described with reference to the drawing. Let's do it.

In the figure, the pair within the boundary line above and below the line indicated by the thick straight line is thermodynamically stable in water. Natural water, in particular, is a region where the stable region is within the vertical boundary between pH = 4 and pH = 9. However, the part outside the boundary line is thermodynamically unstable and has the following characteristics.

That is, when water has a potential and pH corresponding to an upper end (area A) of the stabilization area, that is, an unstable area, it has functions of removing particulate scales and preventing surface oxidation, while the lower end of the stabilization area (area B) When the state has a potential and pH corresponding to the metal has a function of metal removal, organic matter removal, surface oxidation, sterilization.

In the present invention, using the voltaic battery 40 and the ceramic member 4 enables the generation and removal of rust and scale.

First, the function of preventing the formation of rust and removing rust using the water treatment apparatus of the present invention will be described.

As discussed earlier in the discussion of the main causes of rust in piping, the main factor is air and moisture in the air. That is, when water comes into contact with the iron surface, a redox reaction occurs. The OH ⁻ generated at the (+) electrode combines with Fe ^{+ 2} on the iron surface to form Fe ₂ O ₃ , which is iron oxide.

If this is expressed in molecular formula, it is as follows.

+ 2e Fe -------------> Fe ^{++ -}

_{2H 2 O + O 2 + 4e} - ----> 4 OH -

Referring to the molecular formula, the electrons which escape as iron is ionized combine with water and oxygen in the pipe housing 5 to generate hydroxide ions (4OH ⁻ ). The ionized iron ions are hydroxyl ions ^{(4OH -) (Fe ++)} Fe (OH) in conjunction with, and the _second, the Fe (OH) ₂ is a combine with oxygen to Fe (OH) _3, the red color It becomes melted Fe ₂ O ₃ (xH ₂ O). Eventually H ₂ O is water, so only Fe ₂ O ₃ remains.

As a result, the molten hydroxide ion (OH ⁻ ) generated in the pipe and Fe ⁺⁺ ions on the surface of the pipe are bonded to each other and are generated because the surface of the pipe is positive.

Therefore, the water treatment apparatus of the present invention uses the electrochemical reaction using the voltaic battery 40 on the surface of the pipe in contact with water and the far infrared wavelength emitted from the ceramic member 4 to adjust the surface of the pipe to pH 8-10, ORP (- The formation of negative electrode (-) at 400 kPa) to (-800 kPa) prevents the formation of rust by preventing bonding with hydroxide ions.

Next, the scale formation prevention and removal function in a piping using the water treatment apparatus of this invention is demonstrated.

In piping, scale occurs when inorganic and salt components with negative ions and positive ions on the surface of the pipe are coupled to each other due to electrical polarity differences.

Therefore, in the water treatment apparatus of the present invention, the surface of the pipe is negatively polarized at a pH of 8 to 10, ORP (-400 kPa) to (-800 kPa) using the voltaic battery 40 and the ceramic member 4, It also prevents the generation of scale by amplifying a constant electric field in the capacitance of negative ions to offset the deposition of deposits acting on the inner wall of the pipe.

Meanwhile, water is activated (repetitive recombination of two molecules) while water is negatively polarized on the surface of the pipe using the voltaic battery 40 and the ceramic member 4 provided in the water treatment apparatus of the present invention. This self-cleaning ability, which maintains the freshness of the water and does not decay for a long time.

In addition, in the water treatment apparatus of the present invention, the ORP of water reaches up to -800 kPa by the electrochemical reaction by the internal voltaic battery 40 and the far-infrared wavelength emitted from the ceramic member. Is only a few ㎷ can sterilize microorganisms, and further prevent the occurrence of bacteria.

In addition, components such as ammonia (NH ₃ ), ammonia nitrogen, hydrogen sulfide (H ₂ S), and nitrate nitrogen are suppressed and sublimed to remove odors.

5 is a front sectional view of a water treatment device according to another embodiment of the present invention.

The illustrated water treatment device is a device provided with the strainer 9 and the separator 10 at predetermined positions in front and rear of the pipe housing 50.

The strainer 9 installed in the pipe housing 5 serves to filter out contaminants contained in the water flowing along the inside of the pipe in advance, and if the contaminants are not removed, malfunction of the device or expensive machinery It can cause breakage of the components that must be installed.

The water separator 10 passes through the voltaic battery 40 and generates a tornado using a difference in specific gravity between water precipitated by the redox potential difference and precipitates solids, and discharges the solids to the drain valve 17 disposed below the water separator 10. .

On the other hand, Figure 6 is a piping diagram of the water treatment apparatus shown in FIG.

As shown in the piping diagram, the water treatment device 50 of the present invention is installed on a pipe in which water is introduced and discharged, and a drain portion 6 through which sediment is discharged is formed at the bottom of the water treatment device 50. It can be seen that before and after the strainer 9 and the separator 10 are installed.

Water passing through the water treatment device of the present invention is hardly multiplied compared to water that has not passed microorganisms (E. coli and bacteria), and when the device of the present invention is installed in discharged water such as sewage, waste water and sewage, the occurrence of odor disappears. Since there is no green algae, it is possible to reduce ancillary work such as cleaning or cleaning the effluent tank.

Hereinafter, the results shown through the following examples in order to determine the use effect according to the installation of the water treatment apparatus of the present invention.

Example 1

As of the 15th, there was almost no change in the water tank where the water treatment system was installed, but the turbidity and chlorophyll concentration of the water tank that had not been installed increased drastically. .

As described above, the water treatment apparatus of the present invention cathodes the potential of the iron surface in contact with the water by the electrochemical reaction by the voltaic battery embedded in the apparatus and the far infrared wavelength emitted from the ceramic member, thereby It triggers the movement between the opposite poles to change the functional position of the water into a non-corrosive state, and amplifies a constant electric field in the capacitance of the ions causing the scale phenomenon in the drain pipe, thereby inducing the adhesion of deposits on the inner wall surface of the drain pipe. This can prevent and eliminate rust and scale.

In addition, since the present invention is a water treatment device having rust and scale generation inhibition and removal, sterilization, water purification function, and odor prevention function, it is possible to extend the lifespan of buildings and improve the water quality, and to reduce the maintenance cost according to maintenance. It can have a big impact on the piping field.
