Water is the source of life. In addition to human drinking water, water is being used as a functional water for various functions throughout the industry. Functional water includes oxygen water, hydrogen water, OH radical water, oxidized water, and reduced water. The characteristics and efficacy of each functional water are as follows.

Oxygen water is oxygen-dissolved water that helps to grow aerobic microorganisms that help grow crops, eliminates anaerobic microorganisms, improves soil conditions, and provides oxygen to the soil to help grow crops, Increases immunity to.

Hydrogenated water is water in which hydrogen is dissolved, and mainly functions to remove active oxygen, and is used for treatment of skin inflammation and semiconductor cleaning. In addition, the drinking water is excellent in cleansing ability, and it can be seen directly by the fact that the life of the washed fruit is much longer when the fruit is washed with tap water or the like and washed with water. In addition, if you have a lot of hair in your hair, you can see that the hair's freshness will become longer and become longer if you wrap your hair with water.

OH radical water is ozone-dissolved water. It has strong disinfecting power, disinfecting power and deodorizing ability similar to chlorine water, and has no special effect on livestock and crops. Rather, these OH radicals have a rapid absorption rate in the body and promote the metabolism, thereby enhancing the meat quality, growth rate and immunity of the livestock.

The oxidation water is water generated from the (+) polar side when water is electrolyzed and exhibits an acidity (PH) of about 2.5 to 2.7 and an oxidation-reduction potential (ORP, degree to lose electrons and to be oxidized) of about 1,100 to 1,150. Chlorine gas and hypochlorous acid (HOCL) are dissolved in the oxidized water and have strong acidity and high redox potential. These factors combine to produce a fast, yet wide range of bactericidal power. Also, unlike chemical disinfectants, oxidized water is an ideal disinfectant that is non-toxic, non-persistent, and has no unpleasant color or odor.

Reduced water is water produced at the (-) polar side when water is electrolyzed and shows an acidity (PH) of about 11 to 11.5 and an oxidation-reduction potential of about -800 to -850. Reducing water neutralizes the acidified soils and improves soil properties. It contains a large amount of potassium ions, which greatly enhances the growth of crops. In addition, it has germicidal power against some bacteria such as Staphylococcus aureus, and has a strong washing power because it has higher protein and fat solubility than ordinary water.

These functional waters have been proven their efficacy through various clinical trials and are expected to be utilized in the future.

In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

1 to 3, the present invention relates to a method for producing functional water used for sterilization, disinfection, prevention, plant growth, animal drinking and odor removal in various industrial fields such as agriculture, animal husbandry, fishery, The present invention relates to an apparatus for producing functional water using nano bubbles, and includes a scale removing unit 100, a mixing and supplying unit 200, and a tank unit 300.

1, the scale removing unit 100 is coupled to a supply pipe ML into which the raw water W is introduced to remove a scale (not shown) existing in the raw water W. Scale means impurities contained in ozone oxygen, heavy metal ions and water, and solid sediments such as rust.

The scale removing unit 100 may remove the scale included in the raw water W by using ultrasonic waves. When the scale contained in the raw water W is crushed by the ultrasonic wave, the surface area of the scale particle is increased and the scale is finely crushed while repeating the process of re-crushing the scale particles again on the enlarged surface.

By removing the scale included in the raw water W by using ultrasonic waves, it is possible to reduce labor and time for removing the scale, and the scale can be deposited inside the tube to prevent the flow velocity from being lowered or the tube to be clogged.

The raw water W1 discharged from the scale removing unit 100 is mixed with various gases in an unheated state. In order to increase the purity of the raw water W1, it is preferable that the air purge unit 110 is installed in a discharge line of the supply pipe ML through which the scaled down raw water W1 is discharged, and these gases are discharged to the outside.

The raw water W1 discharged from the scale removal unit 100 is temporarily stored in the temporary storage container 120. [ The temporary storage container 120 may be provided with a cold temperature controller 121 for controlling the temperature of the temporary storage container 120. The temperature of the raw water W1 contained in the temporary storage container 120 may be controlled at 4 ° C- 8 < 0 > C to inhibit microbial growth and to maximize the dissolution rate of the functional material (M) to be mixed subsequently.

A scale removing unit and an air purge unit may be additionally installed in the temporary storage container 120 in order to remove scales and various gases present in the raw water W1 stored in the temporary storage container 120. [

The mixing and supplying unit 200 mixes the raw water W1 discharged from the scale removing unit 100 and the functional material M to discharge the functional water W2 containing the nano-sized bubbles V2. Here, the functional material M may include at least one of oxygen gas (O), hydrogen gas (H) and OH radical (R), and the effect of each functional material (M) have.

1 or 2, the mixed supply unit 200 includes a first section L1 having a first cross-sectional area and a first section L1 having a descending flow of raw water W1 connected to the supply pipe ML, A second section L2 continuous with the first section L2 and having a second sectional area that is narrower than the first sectional area and in which the functional material M is sucked by the negative pressure, A third section L3 having a third cross sectional area and generating a micro-sized bubble V1, a fourth section L4 having a fourth cross sectional area continuous with the third section L3 and narrower than the third cross sectional area, And a fifth section L5 having a fifth cross-sectional area continuous with the fourth section L4 and wider than the fourth cross-sectional area, and in which a micro-sized bubble V1 is converted into a nano-sized bubble V2.

The nano-sized bubble V2 is generated while the micro-sized bubble V1 is contracted during the passage through the fourth section L4. The nano-sized bubble V2 has a relatively slow rise speed to the water surface, has a self-pressurizing characteristic, and can maintain a stable shape for a long time by surface charging.

The functional materials M to be mixed in the raw water W in this embodiment are non-polar materials which are not electrically deflected and are not easily dissolved in the raw water W which is a polar material, that is, water. This makes it difficult to maintain the acidity (PH), the redox potential (ORP) of the functional water (W2) or the concentration of the functional material (M) contained therein (the dissolution rate of the functional material) at a certain level, Even if the water (W2) is sprayed on a field or a farm, the functional substances (M) dissolved in the water easily fly into the air.

If the functional material M is easily dissolved in the functional water W2 and is continuously present therein, a relatively small amount of the functional material M is added to the functional water W2, , An oxidation-reduction potential (ORP), or a concentration of the functional material (M). However, since the functional material (M) has opposite characteristics, it is necessary to add more functional material (M) in order to produce the functional water (W2) having the same concentration. It is inefficient.

On the other hand, in the present embodiment, since the functional materials M are contained in the nano-sized bubbles V2 and can maintain a stable shape for a long time, and the bubbles V2 are subdivided into nano- And the time for which the bubble V2 stagnates and remains in the water while the bubble V2 passes through the mixing and feeding portion 200 continuously changing in cross section is lengthened and the time for which the bubble V2 is in contact with the water is increased due to the relatively slow rise speed to the water surface , The dissolution rate of the functional material (M) can be increased as much as possible. It can solve all existing problems.

The tank unit 300 stores the functional water W2 discharged from the mixing and supplying unit 200. [

The functional materials (M) are non-polar materials which are not easily dissolved in water. The higher the pressure of water, the lower the temperature of water, the larger the contact area with water, the longer the residence time in water, The concentration of the acidity (PH), the redox potential (ORP) or the functional material (M) contained therein can quickly reach a certain level and can be maintained more stably.

In order to increase the pressure of the functional water W2, the tank unit 300 is configured as follows.

The tank 300 is provided with a closed structure and the functional material M1 discharged from the functional water W2 contained in the tank 300 is discharged to the upper space 301 of the tank 300 The pressure in the upper space 301 of the tank part 300 gradually rises. As a result, the water pressure of the functional water W2 also increases gradually, and the dissolution rate of the functional material M increases as the water pressure rises. The acidity (PH), the redox potential (ORP) of the functional water (W2) or the concentration of the functional material (M) contained in the functional water (W2) can quickly reach a certain level and can be maintained more stably.

Since the inside of the tank unit 300 is sealed, if the upper space 301 of the tank unit 300 becomes higher than the predetermined pressure, the tank unit 300 can not withstand the pressure and can be damaged. To prevent this, a vent portion 400 and an auxiliary mixing supply portion 500 may be further included.

The vent portion 400 discharges the functional material M1 in the upper space 301 of the tank portion 300 to the outside when the pressure in the upper space 301 of the tank portion 300 reaches a predetermined pressure The auxiliary mixing and supplying unit 500 mixes the functional water W2a discharged and circulated separately from the tank unit 300 and the functional material M1 discharged from the vent unit 400 and mixes the functional water M1 discharged from the mixing unit 200 And supplies it to the first section L1.

That is, the vent portion 400 functions as a safety valve for lowering the pressure inside the tank portion 300, and functions as a safety valve for reducing the pressure inside the tank portion 300, It also functions to supply. The amount of the functional material M to be mixed with the raw water W increases so much that the concentration of the functional water W2 in the acidic PH, the redox potential ORP or the functional material M A certain level can be reached and can be maintained more stably.

The auxiliary mixing supply part 500 may simply mix the functional material M1 discharged from the vent part 400 and the functional water W2 contained in the tank part 300. However, It is preferable to have the same structure as that of the supplying unit 200. [

The pressure pump unit 800 may be further included to increase the pressure of the functional water W2. The pressurizing pump unit 800 raises the pressure of the functional water W2 discharged from the mixing and supplying unit 200 and supplies it to the tank unit 300. [ The pH value of the functional water W2 contained in the tank part 300 is increased by increasing the pressure of the functional water W2 to the tank part 300 by the pressurizing pump part 800, The concentration of the functional material (M) contained therein can be quickly reached to a certain level and can be stably maintained.

The temperature of the functional water W2 in the tank part 300 is lower than the temperature of the functional water W2 in the tank part 300 so that the temperature of the functional water W2 is lowered, The tank unit 300 is heat exchanged with the refrigerant so that the temperature of the functional water W2 contained in the tank unit 300 is maintained at a predetermined temperature or lower, A cooling unit 320 for cooling the unit 300 is provided.

The tank unit 300 may further include a temperature sensor 315 for measuring the temperature of the functional water W2 and may automatically detect the temperature of the heater unit 310 or the cooling unit 320 can be adjusted. It is advantageous in that the temperature of the functional water (W2) is between 4 ° C and 8 ° C in terms of microbial growth inhibition and the dissolution rate of the functional material (M).

The inlet port of the tank unit 300 into which the functional water W is introduced has the same structure as that of the mixed supply unit 200 in order to make the area of contact of the functional material M with the water wider, An end mixing unit 330 may be additionally provided.

With this additional configuration, functional water (W2) having a certain level of acidity, oxidation-reduction potential or functional substance concentration can be rapidly produced, and the same amount of raw water (W) and functional material (M) The water W2 can be efficiently produced.

On the other hand, the functional water (W2) has different kinds of functional materials (M) as required, and the acidity (PH), the redox potential (ORP) of the functional water (W2) ) Are also different from each other. For example, when disinfecting a barn, a functional water (W2) of about 3 ppm containing an OH radical (R) is required. When supplying the crop, the oxygen gas (O) requires 20 ppm or more of hydrogen gas A functional water (W2) of about 3 ppm is required.

First, an electrolytic unit 900 and an OH radical generating unit 1000 may be further included in the functional water producing apparatus using the nano bubble of the present embodiment so that the type of the functional material M can be selected as needed.

3, the electrolytic unit 900 electrolyzes the raw water W1 discharged from the scale removing unit 100 to generate positive and negative ions (WO) and oxygen gas O And a negative electrode 920 for generating reduced water WH and hydrogen gas H, as shown in FIG. The electrolytic unit 900 includes an electrolytic water supply pipe 930 for supplying at least one of the oxidized water WO and the reduced water WH generated in the electrolytic unit 900 to the first section L1 of the mixed supply unit 200, An oxygen supply pipe 940 for supplying at least one of oxygen gas O and hydrogen gas H generated in the electrolytic unit 900 to the second section L2 of the mixed supply unit 200 have.

A plurality of solenoid valves S are coupled to the electrolytic water supply pipe 930 and the water oxygen supply pipe 940 to selectively open and close the oxidizing water WO and the reduced water WH ) Is unnecessary and is not used, it can be discharged and stored in a separate tank.

The amount of the oxygen gas O and the hydrogen gas H generated in the electrolytic unit 900 and supplied to the mixing and supplying unit 200 through the water oxygen supply pipe 940 may be insufficient, And an additional water gas generator 1100 connected to the water supply pipe 940 for generating at least one of the additional oxygen gas O1 and the additional hydrogen gas H1 and supplying the generated additional oxygen gas O1 to the water oxygen supply pipe 940.

The additional water-oxygen generator 1100 includes a gas-only electrolytic cell (not shown) for generating an additional oxygen gas O1 and an additional hydrogen gas H1 through electrolysis, a high-pressure additional oxygen gas O1, And a cylinder vessel (not shown) for storing the hydrogen gas H1.

The OH radical generating unit 1000 is connected to the water oxygen supply pipe 940 and generates the OH radical R to supply the water to the water oxygen supply pipe 940. A solenoid valve S is also coupled between the OH radical generating unit 1000 and the water supply pipe 940 and selectively opened and closed.

In order to adjust the acidity (PH), redox potential (ORP) of the functional water (W2) or the concentration of the functional material (M) contained therein to the functional water producing device using the nano- A controller 600, a flow controller 700, and a controller (not shown).

The measuring unit 600 may measure the concentration of the functional water W2a discharged separately by the auxiliary mixing and supplying unit 500 from the acidity PH, the oxidation-reduction potential ORP or the concentration of the functional material M contained therein Measure at least one. The flow rate controller 700 is coupled to an inlet pipe SL for supplying the functional material M to the second section L2 of the mixing and supplying unit 200 to adjust the flow rate of the functional material M, The flow rate of the functional material M supplied to the second section of the mixed supply part 200 is determined based on the acidity PH of the functional water W2a measured by the measuring part 600, the redox potential (ORP) The flow rate controller 700 controls the flow rate controller 700 to be adjusted in inverse proportion to the concentration of the functional material M contained in the fluid.

It should be noted that the combination of the configurations shown in FIG. 3 and the connection mode are only one way to make the type and concentration of the functional material M different as needed, and can be variously modified.
