In particular, the activation of water by an infrared ray ceramic (Infrared Radiation Ceramic), the sterilization of bacteria by the generated electricity, the prevention of the formation of rust and scale inside the pipe, The present invention relates to a water treatment apparatus capable of removing scales and purifying water by preventing odors and the like.

Generally, minerals and gaseous elements such as various metal elements and minerals are dissolved in water, and these materials adhere to the inside of the pipe by physico-chemical bonding with each other, thereby preventing water flow and heat transfer in the pipe (water pipe). Because of this, there is a problem in that a separate work for cleaning the inside of the pipe.

An example of a water treatment device for solving this problem is Korean Patent No. 0188328 (Name: Corrosion and scale generation prevention device in the steel pipe). In the above patent, the far-infrared wavelength using the voltaic battery and the ceramic is applied to prevent corrosion and scale generation of the pipe generated in the steel pipe. Hereinafter, the configuration of the above-described patent will be described with reference to the accompanying drawings.

1A is a cross-sectional view of a scale generation preventing device in a pipe of the conventional patent exemplified above;

FIG. 1B is a cross-sectional view taken along the line A-A of FIG. 1A.

The device proposed in the above-described conventional patent is formed with water inlet portion 17 and outlet portion 19 at both ends so as to be interposed in a portion of the steel pipe through which water flows, and inside Steel alloy pipe 15 provided with a receiving space of the size, and the aluminum alloy zinc rod is installed in the receiving space of the steel water pipe 15, the aluminum coil (5) densely wound over the outer circumferential surface over the entire length (3), a silver alloy coil 7 wound to a diameter larger than the diameter of the aluminum alloy zinc bar 3, and a plurality of ceramic plate members provided on the aluminum alloy zinc bar 3 at regular intervals ( 9) A voltaic battery formed of a plurality of voltaic battery unit cells formed of a plurality of sets, and an iron porous box 10 surrounding the outer surface of the voltaic battery form a major component part.

However, in the above-described conventional apparatus, foreign matter is frequently caught on the pore cover 6 installed at the inlet 17 of the apparatus and the pore cover 11 provided at the outlet 19, and further, the caught foreign matter is caught. The phenomenon that the pipe is clogged due to the winding of each cover 6 and 11 frequently occurs.

In addition, the foreign matter passing through the cover (6, 11) is not only a phenomenon that is clogged and wound around the perforated part of the porous body 4, but also this phenomenon occurs in the perforated part of the ceramic plate member 9 after installation There was a problem that must be removed frequently.

In addition, the ceramic plate member 9 and the silver alloy coil 7 should be fixed inside the porous body 4, but the method of fixing them was very difficult, and it was not easy to fix the silver alloy coil 7 firmly. There is a problem that the practical use is difficult, and when the water flows inside the pipe, a phenomenon in which the ceramic flat plate member 9 is oriented to one side occurs due to water pressure.

Therefore, the present invention is to solve the above-mentioned conventional problems, an object of the present invention is the activation of water by the far-infrared wavelength radiated from the high purity ceramic member and the sterilization of bacteria by electricity generated in the voltaic battery and the rust in the pipe The present invention provides a water treatment apparatus using a voltaic battery circuit capable of preventing generation and removal of excessive scale and improving the water quality of water flowing in a pipe by providing a odor prevention function.

Water treatment apparatus of the present invention for achieving the above object is a pipe-type piping housing each formed with an inlet and outlet of the water so that water is introduced from one end is discharged to the other end; It is formed of a negative electrode plate which is located in front of the inside of the pipe housing and the disc-shaped member formed through-holes on the inner center and the entire surface, the unit cell located behind the negative electrode plate and a ceramic member mounted therein Electrochemical action by arranging at least one unit cell assembly in the direction of the central axis of the piping housing and by placing a cathode tube on the outside thereof to form a voltaic battery circuit and sterilization and sterilization of water introduced through the far-infrared radiation of ceramics A voltaic battery for removing and preventing scale generation; Is installed at the bottom of one side of the pipe housing and comprises a drain portion for discharging the sediment generated inside the housing, the iron contacted with the water by the electrochemical reaction due to the voltaic battery circuit configuration and the far infrared wavelength from the ceramic member Cathodes the potential of the surface, changes the functional position of the water into a non-corrosive state, and amplifies a constant electric field in the capacitance of the ions causing scale in the pipe to offset the adhesion of deposits on the inner wall of the drain pipe. By inducing, it is possible to prevent the occurrence of rust and scale in the pipe, and to remove the generated rust and scale.

The unit cell is composed of a ring core of zinc alloy, a silver alloy coil and an aluminum coil wound around the ring core, and a silver alloy coil provided in each unit cell between the cathode tube and each unit cell assembly inside the cathode tube. And it is preferable to have a structure in which one end of the aluminum coil extends through the ceramic member to be bound.

Hereinafter, the basic principles of the electrochemical reactions related to water treatment will be described in order to help the understanding of 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 from (+) 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 joining by 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 a water treatment apparatus using a voltaic battery circuit according to the present invention will be described in detail with reference to the accompanying drawings.

4A is a perspective view of a water treatment apparatus using a voltaic battery circuit according to a first embodiment of the present invention;

4B is an exploded perspective view illustrating an enlarged view of a part C of FIG. 4A;

4C is a cross-sectional view taken along line B-B of FIG. 4A.

Referring to the drawings together, the water treatment apparatus 100 using the voltaic battery circuit according to the first embodiment of the present invention is a pipe housing 120 is formed with a passage through which water flows, and the inside of the pipe housing 120 It is configured to include a voltaic battery 190 to provide a function to clean the flowing water installed in the pipe and prevent the formation of rust and scale in the pipe and to remove the generated rust and scale.

The pipe housing 120 of the present invention is formed with flanges 110 to be easily coupled to any pipe at both ends, respectively, the water inlet 111 to allow water to be introduced from one end and discharged to the other end; The water outlets 113 are formed, respectively, and have a substantially pipe-like shape with a larger diameter at a constant length in the center than both ends.

In the voltaic battery 190 of the present invention installed inside the pipe housing 120, at least one unit cell assembly 170 is arranged in series in the direction of the central axis of the pipe housing 120, and a cathode tube disposed at an outer side thereof. 130).

The unit cell assembly 170 has a structure in which the ceramic member 160 is bound to the unit cell 150, and the unit cell 150 is a ring core 151 of zinc alloy, as shown in FIG. Consists of a silver alloy coil 152 and an aluminum coil 153 wound around the ring core 151, the silver alloy coil 152 and the aluminum coil 153 is a pair of the ring core 151 It has a structure that is wound around.

In particular, the screw fixing part 155 is formed at regular intervals along the circumference of the ring core 151 for binding between the ring core 151 and the ceramic member 160 on the outside thereof. The screw fixing part 155 is a member that protrudes a predetermined length in the outer radial direction on the outer surface of the ring core 151, the spiral is formed on the inner side to facilitate the fastening of the screw.

The unit cell 150 is provided with a cathode tube 130 on the outside thereof, the silver alloy coil 152 and the aluminum coil 153 wound around the ring core 151 of the unit cell 150 is the cathode tube 130 When formed in a structure connected to, it constitutes a battery constituting one voltaic circuit. With the configuration of the voltaic circuit, a virtual positive (+) electrode is formed at the inner center portion of the ring core 151, and the cathode tube 130 positioned outside the ring core 151 has a negative (-) pole.

In particular, when such a voltaic battery circuit is formed in water, the water located in the stabilization region is activated to change the pH and the redox potential (ORP).

That is, referring to FIG. 2, which shows the functional property region of water described above, when water is activated, water moves to region A and region B, respectively. At this time, the A region corresponds to the unit cell 150 side, and the characteristics of the oxidized water appear, so that the functions of metal removal, organic matter removal, surface oxidation prevention, sterilization, etc. appear in the water, and the B region corresponds to the cathode tube 130 side. It has the characteristics of fine particle scale removal and surface oxidation.

The ceramic member 160 of the present invention is formed with a diameter larger than the diameter of the ring core 151 to accommodate and bind the ring-shaped unit cell 150 therein and has a width W of a predetermined size. It is in the form of a cylindrical tube. A first through hole 163 for screwing is formed at a position corresponding to the screw fixing part 155 of the ring core 151 around the ceramic member 160, and further formed in the ring core 151. A second through hole 166 is provided to provide a passage so that the wound coils 152 and 153 may pass through the ceramic member 160 and exit to the outside.

The position of the first through hole 163 may vary depending on the shape of the screw fixing part 155 installed in the ring core 151. For example, as in the embodiment, the screw fixing part 155 Is installed at intervals of 90 degrees along the circumference of the ring core 151, so that it may be formed at the same intervals along the circumference of the ceramic member 160 can be convenient when binding. In addition, the second through hole 166 may be formed at an arbitrary position to avoid the position of the first through hole 163.

In addition, since the ceramic member 160 is connected in series in the direction of the center axis in the state in which the unit cells 150 are bound therein, the outer surface of the one-side end portion 161 to be connected is formed to be inclined downward and adjacent to the ceramic member 160. To facilitate the coupling with the ceramic member. At this time, the end connecting portion 161 of the ceramic member 160 has a flat outer surface and the inner surface of the end portion is bent inward.

On the other hand, the end connecting portion 161 of the ceramic member 160 may reverse the shape of the end connecting portion of the ceramic member 160, and in this case, the structure of the end coupling portion is protruded from the outer surface thereof and the inner surface thereof. Becomes flat.

The cera membrane member 160 generates far-infrared rays to purify the water quality and serves to remove odors in the water. That is, water is an absorber of electromagnetic waves having a great contrast of dielectric constant or relative dielectric constant, and is a combination of oxygen atom (+) and hydrogen atom (-). When an electric field is generated, gas is contained in intense vibration and frictional motion between atoms. Molecules sublimate and inorganic materials are activated in an exclusive situation. If this condition persists, the binding force between the water molecules becomes stronger and more activated. That is, the carbon dioxide gas increases, and the hydrogen ion concentration (pH) increases.

In the above example, the four unit cell assemblies 170 are arranged in series in the central axis direction, and the cathode tube 130 is positioned on the outside thereof, and a coil (coil) is formed between the cathode tube 130 and the unit cell assembly 170. 152 and 153 are connected to each other through the second through hole 166 of FIG. 4B.

In particular, each unit cell assembly 170 is formed such that the direction in which each of the coils 152 and 153 passes through the second through hole 166 of the ceramic member 160 and is drawn out toward the cathode tube 130 is generally zigzag along the central axis direction. ) And the cathode ray tube 130 are structurally stabilized. In order to draw out the coils 152 and 153 in a zigzag shape, the withdrawal direction of the coils 152 and 153 in each unit cell assembly 170 may be opposite to that of the coils 152 and 153 in the adjacent unit cell assembly 170. .

That is, the silver alloy coil 152 and the aluminum coil 153 have a certain rigidity, thereby connecting the unit cell assembly 170 and the cathode ray tube 130 to partially maintain the binding force between the two components. Done.

In addition, the unit cell assembly 170 located at both ends is provided with a separate fixing member 135 to firmly bind the cathode tube 130 and the unit cell assembly 170. At this time, the auxiliary support member 136 is added to the rear of the fixing member 135 so that the binding of the fixing member 135 is more stable.

In order to bind the ends of the coils 152 and 153 to the cathode tube 130, in the illustrated example, a separate fixing bolt 165 is inserted into the through hole 131 formed in the cathode tube 130. . However, without using this method, the ends of the coils 152 and 153 may be directly bonded to the cathode tube 130 by welding.

The cathode tube 130 located at the outside of the unit cell assembly is joined by welding with the inner surface of the outer pipe housing 120 near both end portions thereof, and the welding joint (121 in FIG. 4C) is connected to the cathode tube 130. It is formed on the outer circumference of both ends. In this case, a space may be formed between the cathode tube 130 and the inner surface of the pipe housing 120 according to the binding method of the two members or may be formed in a close contact with the space without forming a space.

On the other hand, in the unit cell assembly 170 of the present invention, the silver alloy coil 152 is excellent in electrical conductivity serves to transfer the current from the battery cell to the cathode tube 130 having a negative electrode, the aluminum coil 153 is ^{(Al → Al +3 + 3e -} ) is ionized to Ag alloy coil (152) and to prevent adhesion of the corrosion and sludge in the cell to keep clean the contact between the cell and the coil to a constant electric current of the induction It plays a role.

In addition, the drain portion 123 is formed on one side of the bottom of the pipe housing 120 to allow the sediment generated inside the pipe housing 120 to be discharged to the outside.

5A to 5C are views illustrating a water treatment apparatus using a voltaic battery circuit according to a second embodiment of the present invention.

5A is a perspective view of a water treatment device according to a second embodiment of the present invention,

5B is an enlarged perspective view of portion D of FIG. 5A;

5C is a cross-sectional view taken along the line E-E of FIG. 5A.

In the water treatment apparatus 200 according to the second embodiment of the present invention, the negative electrode plate 210 is installed on one side of the unit cell assembly 170 ′. The negative electrode plate 210 is a disc-shaped member, the main through hole 211 having a predetermined size is formed in the inner center, the auxiliary through hole 213 having a smaller size than the main through hole 211 on the entire surface The formed through, through the main through hole 211 to facilitate the flow of water flowing along the central axis of the inside, through the auxiliary through hole 213 is smoothly dispersed in the interior of the pipe housing 120 It plays a role to get out.

One side end of each of the negative electrode plates 210 is connected to the silver alloy coil 152 and the aluminum coil 153 provided in the unit cell 150.

In the example shown in FIG. 5C, the negative electrode plate 210 is inserted into the ceramic member 160, and is bonded to other adjacent unit cell assemblies 170 ′ in the same shape, such that the negative electrode plate 210 is arranged like a partition. It is. Unlike the above structure, the binding of the negative electrode plate 210 may be performed by using a separate fixing member on the outside of the ceramic member 160.

Since the negative electrode plate 210 is impinged in a vertical direction with respect to the flow of water, when the flowing water contacts the negative electrode plate 210, the negative electrode plate 210 becomes negative, and the water passing through the negative electrode plate 210 is unit cell assembly 170 positioned at the rear thereof. At the moment of passing through the ring core 151 of ′), the water negatively polarized by the virtual anode formed at the inner center of the ring core 151 is again polarized, so that the polarization and the cathodic polarization are stirred as the water flows, thereby activating the water. Purification due to this will be active.

In the water treatment apparatuses 100 and 200 of the present invention illustrated above, the ceramic member 160 located outside the unit cell 150 is a high purity ceramic member, which activates water to promote the self-cleaning ability of the water, To maintain 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, the weak alkaline water is fast absorption of the plant and the invasion of pathogens is very difficult compared to the general water and sterilize the bacteria, so the growth of the plant is fast, the fruit is large, and has a strong resistance to pests.

Water treatment apparatus (100,200) using the voltaic battery circuit of the present invention configured as described above is simple to install and disassemble the components compared to the conventional water treatment apparatus exemplified above, the structure of the device is simple and miniaturized in the manufacturing process Efficiency is improved, which can lead to cost reduction.

Hereinafter, the functional properties of the water will be described with reference to FIG. 2 to help understanding of the present invention.

FIG. 2 is a diagram illustrating 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.

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, by using the water treatment apparatus (100,200) using a voltaic battery circuit formed by combining a plurality of unit cells 150, the ceramic member 160 and the cathode tube 130 to prevent the generation of rust and scale in the pipe Can also remove rust and scale produced.

First, an operation of preventing rust from being generated in a pipe using the water treatment apparatus 100 and 200 using the voltaic battery circuit of the present invention and removing the rust will be described.

As discussed in detail above, the main factor in the formation of rust in the piping is the air and the moisture in the air. That is, when water comes into contact with the iron surface, a redox reaction occurs. The OH ⁻ ions generated at the (+) electrode combine 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 Fe ₂ O ₃ (xH ₂ O) which melted. 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 a voltaic battery on the surface of the pipe in contact with water and uses the far-infrared wavelength emitted from the ceramic member to adjust the surface of the pipe to pH 8-10, ORP (-400㎷) to (- 800 ㎷) to cathodic (-) to prevent the formation of rust by preventing bonding with hydroxide ions.

Hereinafter, a function of preventing rust and scale from forming in the steel pipe and removing the rust and scale generated by using the water treatment apparatus 100 and 200 using the voltaic battery circuit of the present invention will be described.

The scale generated in the steel pipe is generated by the combination of inorganic and salt components with negative ions and positive ions on the surface of the steel pipe due to electrical polarity differences.

Therefore, in the water treatment apparatus 100 or 200 of the present invention, the voltaic battery 190 is formed by combining a series of structural members including the unit cell 150, the ceramic member 160, and the cathode tube 130. To a negative polarity at a pH of 8 to 10, ORP (-400 kPa) to (-800 kPa), and to amplify a constant electric field in the capacitance of negative ions to act as an inner wall of the steel pipe. By inducing adhesion, this prevents the generation of scale.

Meanwhile, in the process of negatively polarizing the surface of the steel pipe by using the voltaic battery 190 including the unit battery cell 150 and the ceramic member 160 provided in the water treatment apparatus 100 or 200 of the present invention, As the water is activated (repetitive recombination of two molecules), the water has a 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 (100,200) of the present invention, the ORP of water reaches up to -800 의해 by the far-infrared wavelength from the ceramic member 160 and the electrochemical reaction by each of the unit cells 150 embedded, compared to the microorganism The potential required for sterilization of is only a few kW to sterilize microorganisms, and further prevent the generation 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.

Water that has passed through the water treatment apparatus (100,200) 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, wastewater, and sewage, Since the occurrence disappears and there is no green algae, it is possible to reduce ancillary operations such as cleaning or cleaning the effluent tank.

Hereinafter, the results shown through the following experimental example to describe the use effect according to the installation of the water treatment apparatus of the present invention.

The experiment was performed to run the two freezers under the same conditions for six months in the absence of a state.

In order to determine the effect of the installation of the water treatment apparatus of the present invention, the following two measurement methods were applied to Experimental Example 1.

First, the integrated power meter was attached to each of the selected refrigerators, and a method of comparing energy consumption by measuring the amount of power consumed in each refrigerator during the six month experiment period was applied.

Secondly, after the end of the six-month experiment period, the method was used to photograph the state inside the pipe with an endoscope, and then read and compare the state with the naked eye.

Based on the results shown in Table 1, the effect of installing the water treatment apparatus of the present invention can be calculated by the following formula.

 M1 = $ 6,115-$ 5,500 = $ 640 (saved amount)

 M1 / M2 = 640,600 won / 6,115,600 => about 11%

In the above,

M1: Difference in the amount of electricity consumed between a freezer equipped with a water treatment device and a control freezer

M2: Total electricity required for 6 months in the control refrigerator

As can be seen from the above formula, the difference (M1) of the amount of energy used in the selected two injection refrigerators is 640,600 won, and this amount is about 11% energy saving effect by applying the water treatment apparatus of the present invention. Indicates that it can be obtained. It can be seen that the rust and scale formed in the pipe is a significant obstacle to the cooling and heating effect in the freezer.

6A and 6B are photographs showing a state in which the selected internal pipe state is taken by an endoscope after a six-month experiment period ends.

Figure 6a is a photograph taken a state in the pipe without the water treatment apparatus of the present invention,

6B is a photograph of a state in the pipe in which the water treatment apparatus of the present invention is installed.

As can be seen from the figure, rust and scale 310 is formed entirely in the pipe where the water treatment apparatus of the present invention is not installed, whereas rust and scale are generated inside the pipe where the water treatment apparatus of the present invention is installed. You can see that it is kept clean.

Therefore, it can be seen from the comparison of the two pictures that the effect on the installation of the water treatment device of the present invention is clearly shown, in particular, the occurrence of rust in the pipe means the corrosion of the pipe, and further shorten the life of the pipe as rust is generated, Facility maintenance costs will also increase.

Experimental Example 2

In the present experimental example, two aquariums having the same conditions were selected and one aquarium was provided with the water treatment apparatus of the present invention, and the other aquarium was set for control without the water treatment apparatus.

In each of the aquariums, the general subsidiary materials necessary for the aquarium, such as the amount of water, sand, water temperature, and the like under the same conditions, and the ornamental fish housed together, the same species and the same size of the ornamental fish was used.

The measurement method applied in the above experiment is as follows.

First, the experiment period is set to 60 days, and the water quality state change, such as COD, turbidity, conductivity, pH, ORP, total nitric acid amount, total phosphorus, hardness, chlorophyll, Zn, etc. over 6 times based on about 10 days The measurement and analysis were performed to obtain the results as shown in Table 2 below.

 <Table 2> A table showing the results of water quality check items in an aquarium measured after a certain period of time when the water treatment apparatus of the present invention is installed in a water tank or not.

In order to examine the trend of each item based on the result of <Table 2>, the change of each item is shown as a graph of FIGS. 7 to 11.

That is, FIG. 7 is a graph showing a COD change trend, FIG. 8 is a turbidity change trend, FIG. 9 is a pH change trend, FIG. 10 is an ORP change trend, and FIG. 11 is a graph showing a conductivity change trend.

First, referring to FIG. 7, it can be seen that the change in COD increases with time, and the increase in COD is caused by feed supplied to the aquarium, bacteria in the water, other microorganisms including algae, and fish droppings. do.

And after 30 days, the COD was twice as large as the control aquarium without the water treatment apparatus compared to the aquarium with the water treatment apparatus of the invention. This indicates that the installation of the water treatment apparatus of the present invention has the effect of reducing the concentration of organic matter in the water.

For reference, substances that cause turbidity in a relatively stagnant state such as an aquarium are organic and inorganic colloidal particles of about 1 μm or less, and are generally charged, and colloidal particles are highly stable due to their size and charge, and thus rarely settle. This doesn't work.

In addition, colloidal particles are classified into hydrophilicity and hydrophobicity according to the degree of affinity with water. Inorganic colloidal particles have a hydrophobic charge, and among the organic compounds, they are dissolved in water but do not form a true solution. They are usually present as very weakly charged hydrophilic colloids. Turbidity-inducing substances in this experiment are particles of complex properties of hydrophobic particles, and these hydrophilic colloidal particles (organic) are combined with heavy metals to form insoluble salts, which tend to be precipitated and removed. It is determined that the turbidity of the aquarium is kept relatively constant, and for this reason, the increase in the concentration of organic matter (COD) in the water in the aquarium in which the water treatment apparatus of the present invention is installed is low.

Referring to FIG. 8, in turbidity, the aquarium in which the water treatment device is installed is largely unchanged during the experiment, while the control aquarium is similar to the aquarium in which the cell is installed at the beginning of the experiment. You can see it happen.

Referring to FIG. 9, when the water treatment apparatus of the present invention is installed, the pH is kept relatively constant, whereas the control aquarium gradually increases the pH. This increase can be explained by the change in the final concentration of chlorophyll shown in Table 2 above. In other words, chlorophyll is a substance that all freshwater algae have in common and is used as an indicator of algae generation. Algae are carbon-assisted vegetable aquatic organisms that grow rapidly with appropriate sunlight, temperature, and nutrients. In general, the aquarium used in this experiment is well suited to these conditions. When the photosynthetic activity of the algae can absorb inorganic carbon hwalbalhal of the HCO ₃ and CO ₃ and OH ^- sikimeuro caused the increase of water pH. Therefore, the increase of the pH of the control aquarium is caused by the increase of algae, and the aquarium where the cells are installed has a relatively constant pH due to the suppression of algae generation, which is a major factor in causing turbidity, and the removal of a significant amount of the generated algae. to be.

In the case of total nitrogen and total phosphorus shown in Table 2, it was also measured in the control aquarium, which is high compared to the characteristics of the ORP shown in FIG. 10, because the control aquarium is generally aerobic atmosphere (especially after 20 days) ) Oxidation was promoted from organic nitrogen and phosphorus (NH ₄ , NO ₂ , NO ₃ ) and inorganic phosphorus (PO ₄ ), which are essential factors for algae production.

Referring to FIG. 11, the electrical conductivity is a comprehensive measure of the concentration of ionic solutes in water and is an indicator for measuring the ability of a solution to flow an electric current. The difference in conductivity between the two aquariums was substantially absent, mainly due to the increase in inorganic pollutants in the water, since soluble organics without charge were not measured in conductivity, regardless of their amount.

Although the hardness represented by the calcium (Ca) and magnesium (Mg) of the <Table 2> is not shown in the graph, it was found that there is no difference in hardness because the initial concentration and the final concentration in both aquariums are similar. The increase in is believed to be due to the supply of trace elements in the feed.

The concentration of zinc (Zn) in water was detected in aquariums with water treatment devices, but lower than expected concentrations of zinc ions in water were controlled by the formation of insoluble salts by the combination of zinc ions and organic colloidal particles described in the turbidity change. Because The detection of zinc in the control aquarium is also due to the trace elements in the feed.

On the other hand, Figure 12 is a view showing a photograph of a sample taken from the aquarium and the control aquarium in which the water treatment apparatus of the present invention is installed.

As can be seen in the figure, the appearance of the aquarium seems to be no significant difference between the two aquarium due to the algae attached to the wall of the aquarium, it can be seen that the sample taken from the aquarium is clearly distinguished algae generation.

In addition, the sensory odor was found to be much lower than that of the aquarium in which the aquarium in which the water treatment apparatus of the present invention is installed is generally felt than the control aquarium. This is closely related to the incidence of algae, because algae usually cause fishy fishy, rotting or moldy odors.

On the other hand, the results of observing the growth of the ornamental fish put in the experimental aquarium of the present invention is shown in Table 3 below.

The numerical values indicated in the ornamental fish growth observation experiment is the average of the size of the fish after the initial and 30 days of the ornamental fish by species.

Referring to <Table 3>, since the initial growth of fish and the intake of food for each fish are different, the results cannot be expressed uniformly, but the growth in the aquarium equipped with a water treatment device is shown to be rather fast. have.

As described above, in the water treatment apparatus using the voltaic battery circuit of the present invention, the surface of the iron pipe in contact with water is cathodic and alkalized by using a voltaic battery including a unit cell, a ceramic member, and a cathode tube. It prevents the binding of hydroxide ions and iron ions to block the formation of rust. The rust produced is ionized and at the same time separated by weakening of the binding force, some are reduced to iron and some are dissolved in water and are gradually removed. do.

In addition, in the water treatment apparatus using the voltaic battery circuit of the present invention, the surface of the steel pipe is cathodic on the surface of the pipe by using the voltaic battery and the ceramic member, and the precipitate that acts as the inner wall of the pipe by amplifying a constant electric field to the capacitance of the anion. Radically cancels adhesion of the scale, and the pre-formed scale is dissolved due to the increase of carbon dioxide concentration due to the activation of water, and the scale formed due to the weakening of adhesion due to the cathodic and alkalinization of the pipe wall is gradually separated. It remains as a radish and some of it dissolves in the water and has a slow removal effect.

In addition, in the water treatment apparatus using the voltaic battery circuit of the present invention, water is activated in the process of cathodic and alkalizing the metal surface using the voltaic battery and the ceramic member, so that the water has a self-cleaning ability, resulting in an incidental sterilization effect and thus the freshness of the water. To maintain the effect. With this effect, the water treatment apparatus of the present invention can be usefully used in aquariums and the like.

In addition, in the water treatment apparatus using the voltaic battery circuit of the present invention, the ORP of water reaches up to 800 kPa by the electrochemical reaction by the voltaic battery mounted therein and the far-infrared wavelength emitted from the ceramic member. It is possible to prevent the generation of bacteria by the source, thereby reducing the pipe corrosion and the production of components such as ammonia, ammonia nitrogen, hydrogen sulfide, nitrate nitrogen by the metabolic action of microorganisms to remove odors Exert.

In addition, since the present invention is a water treatment device having the rust and scale generation suppression, sterilization, water purification function, odor prevention function, etc. as described above, water treatment, such as reducing the maintenance cost according to maintenance by extending the life of the piping in the building and water quality improvement It can have a big impact on the field and various piping fields.
