Description

Vase water electrolysis device using sodium chloride as an electrolyte}

The present invention relates to a water electrolysis device for vases using sodium chloride (NaCl) as an electrolyte for providing optimal water for the color of cut flower hydrangea by electrolyzing water in a vase to adjust the pH.

In addition, the present invention relates to a technique for sterilizing water and removing chlorine contained in tap water.

Freshness is maintained for a long time by adding a small amount of calcium chloride to tap water with an electrolysis device to electrolyze it, and using acidic water for flower arrangements.

For example, the freshness of cut roses or cut carnations can be maintained at 1.5 to 2.5 times the freshness of tap water. In cut roses, the sterilization effect of acidic water suppresses the growth of bacteria in the water, promoting the rise of the stem, and in the case of cut flowers, such as cut flowers, it decomposes ethylenic, which causes them to wither quickly, so that freshness is maintained for a long time. It is also effective in statis and lilac.

Electrolyzed water is an aqueous solution having a useful function produced by electrolysis by adding an electrolytic aid such as salt or hydrochloric acid to tap water or tap water. Electrolyzed water can be largely divided into electrolyzed drinking water and electrolytically sterilized water. Electrolyzed drinking water is weak alkaline electrolyzed water for home use mainly for drinking purposes, and electrolytic sterilized water is for sterilization, and there are strong acidic electrolyzed water, slightly acidic electrolyzed water and electrolytic sodium hypochlorite water.

The hydrogen ion concentration index or the hydrogen concentration index is a ^{value expressed by taking the inverse logarithm of the dissociation concentration of hydrogen ion (H +} ), and the unit is pH, and is used as a measure of the strength of acids and bases of a substance. Hydrogen ion activity in aqueous solution is expressed by the interaction between the dissociation constant of water and other ions. Is an aqueous solution of neutral activity and hydroxide ions (OH ^-) of the hydrogen ion (H ⁺⁾ it has a value of pH = 7 at standard temperature and pressure (STP), so that the same activity. If the pH value is lower than 7, it is said to be acidic, and if it is higher than 7, it is said to be basic.

The electrolytic sterilization water changes the form of chlorine present in the water depending on the pH, and the sterilization power is very different accordingly. Depending on the pH, it is classified into strong acidic electrolyzed water, weakly acidic electrolyzed water, and electrolytic sodium hypochlorite water. Strong acidic electrolyzed water is electrolyzed in a semi-permeable diaphragm type electrolyzer 30 with saline solution (NaCl concentration of 0.2% or less) added in a trace amount of sodium chloride to tap water 32, and an acidic aqueous solution containing hypochlorous acid obtained from the anode side as an active ingredient is strongly acidic. It is called electrolyzed water.

Household weak alkaline electrolyzed water is produced by electrolysis with weak electric current by adding calcium glycerate to water after chlorine has been removed with activated carbon, and it is water for drinking and skin cleaning. Electrolytic sterilization water is generated on the anode (+) side of the electrode when electrolysis is performed by adding an electrolyte of salt or hydrochloric acid to water.

Slightly acidic electrolyzed water is a slightly acidic aqueous solution containing hypochlorous acid as the main active ingredient obtained by electrolyzing diluted hydrochloric acid in a non-diaphragm type electrolyzer to mix and dissolve the entire amount of the electrolyte other than hydrogen gas in raw water. The active ingredient in non-acidic electrolyzed water is hypochlorous acid and the pH is 5.0-6.5. In addition, the effective chlorine concentration is 10 to 30 mg/kg and is colorless, and it is usually odorless but has a slight odor of chlorine. Looking at the principle of generation of non-acidic electrolyzed water, chlorine is generated at the anode by electrolysis from diluted hydrochloric acid supplied from the non-diaphragm electrolyzer, and hydrogen is generated at the cathode. The produced chlorine is dissolved in water, and a high-concentration hypochlorous acid solution is continuously produced from the electrolyzer. When this is diluted in raw water, it becomes non-acidic electrolyzed water with an effective chlorine concentration of 10 to 30 ppm. The hydrochloric acid of the strong acid decreases by electrolysis, and the hypochlorous acid of weak acidity is produced. It becomes slightly acidic at pH 5.0-6.5 by the buffering action caused by the hardness component in raw water.

Sodium hypochlorite water refers to water containing sodium hypochlorite as an active ingredient, and also includes water obtained by electrolysis of saline solution. It is a pale greenish yellow liquid with a chlorine odor. Looking at the principle of generating electrolytic sodium hypochlorite water, 3% of saline solution is electrolyzed in a non-diaphragm electrolyzer to generate chlorine at the anode and hydrogen and caustic soda at the cathode.

The produced chlorine is dissolved in water and reacts with caustic soda to produce about 1% or less of sodium hypochlorite water.

Hereinafter, specific details for carrying out the present invention will be described with reference to the accompanying drawings. FIG. 2 is a photograph of a color comparison of hydrangea according to the pH of nutrients, and FIG. 3 is a graph showing a change in lifespan of cut flowers according to pH,

2 is a photograph of a color comparison of hydrangea according to the pH of nutrients.

As shown in Figure 2, the color of the hydrangea appears different depending on the pH of the nutrients.

The blue line (10) of the left hydrangea (Hydrangea macrophylla'Blue Heaven') is acidic, and the pink line of the right hydrangea (20) (Hydrangea macrophylla'Endless summer') is the hydrangea grown in alkaline.

Hydrangeas have many types and various colors, but generally, if pH 3.0 or more and pH 5.2 or less, the blue series, if the pH exceeds 5.2 to less than pH 7.0, the purple series, and the pH 7.0 or more and less than the pH 7.4, pink/red flowers bloom. It is a feature.

In hydroponic cultivation of hydrangea, the adjustment of the supply pH causes a change in the content of aluminum in the plant, and the change in aluminum content is deeply related to the change in the flower color of the hydrangea calyx.

The principle of color change is that hydrangea flowers become reddish by a pigment called anthocyanin. If there is not much aluminum in the soil, pink or red flowers will bloom as it is. If there is a lot of aluminum in the soil, anthocyanins combine with aluminum and the flowers turn blue. Changes. Blue flowers contain five times more aluminum than pink flowers.

The color change does not apply to all hydrangeas, but includes the most common and popular pink or blue flowers, Hydrangea macrophylla, and the Hydrangea serrata hydrangeas, also known as hydrangea.

Hydrangea arboresens, which have white flowers, Hydrangea anomala, Hydrangea quercifolia, Hydangea paniculata, and round, large ball-shaped white flowers, still bloom white even when soil pH changes.

Hydrangea's viable soil has a pH of 3.0 to 7.4, and at around pH 7.4, obstacles can occur. It is important to adjust the pH to provide the most suitable water for the flower arrangement of cut flower hydrangea. If electrolysis is used to adjust the pH, it is possible to very effectively provide water that matches the color of the cut flower hydrangea.

3 and 4 are graphs showing changes in lifespan of cut roses according to the pH of nutrients.

Since the petals, which are the determinants of the lifespan of cut flowers, have the shortest lifespan, they are used as an index to determine the lifespan of cut flowers. The number of days of cut flower life according to the type of preservation solution was measured at intervals of one day after the start of the experiment. In the case of cut flowers (variety: Vital), the cut flower life was measured when a bent-neck occurred, and the cut flower life for each type of water was distilled water. Was 7.3 days, tap water 8 days, pH 3.5 11 days, pH 10.2 11 days. From this, it was found that the cut flower life was the longest in strong acidic (pH 3.5) and strong alkaline (pH 10.2) water, showing 37.5% longer than tap water in strong acidity and strong alkali.

In the case of cut flower preservative treatment, pH 3.5 (11.7 days)> pH 10.2 (11.3 days)> distilled water (11 days)> pH 5.3 (10 days)> tap water (8.3 days). ) Or strongly alkaline (pH 10.2) water has been shown to increase the life of cut flowers.

5 is a diagram showing a general electrolysis of water.

In the present invention, the method of adjusting the pH of water is a method by electrolysis. Tap water 32 is put in the electrolyzer 30, a semi-permeable membrane 60 is placed between the anode 40 and the cathode 50, and the power source 33 is applied to perform electrolysis. If the electrolysis of pure water (H ₂ O) hydrogen ions (H ⁺⁾ and oxygen ions (O ^-), and the generation, tap water contains chlorine (Cl) due to loading the chlorine (Cl) for the disinfection of oxygen and meet the goats OCI ^- it is the (active chlorine).

In addition, electric H ₂ O ₂ (hydrogen peroxide), O ₂ generated during the decomposition ^(oxidation ion), ^OH-bacteria to destroy the oxidized (hydroxyl group), such as a combination with H ^+, forming a film of bacteria, such as film and die . In this way, it is returned to water (H ₂ O) while destroying the membrane by taking away hydrogen.

A process of electrochemically removing chlorine ions by electrolyzing the tap water 32 will be described. Tap water introduces an excess of chlorine through the water purification process, and in this case, the added chlorine reacts with water to produce hypochlorous acid and hydrochloric acid as shown in the following equation (1). In other words

H ₂ O ₂ + Cl ₂ → HOCl + HCl Equation (1)

And hypochlorous acid (HOCl) produced by Equation (1) reacts as in Equation (2) below to ionize into hydrogen ions and hypochlorous acid ions.

HOCl → H ⁺ + OCl ^- Equation (2)

And at the same time, hydrochloric acid (HCl) in Equation (1) is ionized as in Equation (3) below.

HCl → H ⁺ + Cl ^- Equation (3)

As a result, hypochlorous acid, hypochlorous acid ions, chlorine ions, and hydrogen ions are present in tap water generated by the water purification treatment as described above.

When such tap water is electrolyzed, acidic water is produced by reacting as shown in the following equation (4) in the anode chamber. In other words,

2H ₂ O → O ₂ + 4H ⁺ + 4e Equation (4)

In the cathode chamber, alkaline water is produced by reacting as in the following equations (5) and (6) to generate hydroxide ions.

O ₂ + 2H ₂ O + 4e → 4OH ^- Equation (5)

2H ₂ O + 2e → H ₂ + 2OH ^- Equation (6)

In addition, anions such as chlorine ions contained in the tap water 32 of the cathode chamber move to the anode chamber through the semipermeable membrane 60, and the cations in the anode chamber move to the cathode chamber.

Sodium chloride, the chloride ion (Cl ^-) in the positive electrode (anode) (+) (40 ) (NaCl) using the electrolyte is oxidized generate a chlorine gas (Cl _2), and a negative electrode (cathode) (-) (50 ) in the Water (H ₂ O) is reduced to generate _{hydrogen gas (H 2 ).}

First, while the cut flower hydrangea is flower arrangement in a vase, a trace amount of sodium chloride (NaCl concentration 0.2% or less) is added to tap water, and the positive electrode (+) is applied to the part where the cut flower part of the hydrangea is submerged. Next, power is applied in the power-on step (S10).

In the step (S20) of determining whether a pH is greater than or equal to 2.2 to less than or equal to 2.7, water is acidified to a value of greater than or equal to 2.2 to less than or equal to 2.7 to sterilize, and in this process, chlorine contained in tap water is removed.

In the step of determining whether 5 minutes have elapsed (S12), most of the microorganisms in the water and in the vase are sterilized, and thus the power is cut off as the power OFF step (S13) after 5 minutes have elapsed.

Subsequently, as a step (S14) of switching the polarity of the power source (S14), the part where the cut section of the hydrangea is locked is switched from the original (+) to the negative (-) power supply, and the power ON step (S15) proceeds. do.

Subsequently, the process proceeds to the step (S16) of determining whether or not pH 3.0 or higher to pH 5.2 or lower to suit the blue-based hydrangea, and if the pH is maintained between 3.0 or higher and pH 5.2 or lower, the power is cut off as the power OFF step (S17). Subsequently, in the step of determining whether the pH exceeds 5.2 (S18), the water becomes neutral after a certain period of time, so the power polarity is re-switched in the power polarity re (+)(-) switching step (S19), and the power ON step It consists of a step (S20) returning to (S15). In any of the above steps, the power is turned off when the vase is water exchanged or the flower arrangement is finished.

The process after the step (S19) of returning to the power ON step (S15) continues to be repeated unless the vase is replaced with water or the flower arrangement is terminated.

7 is a flowchart showing an electrolysis process when cut flower hydrangea is purple.

When the cut flower hydrangea according to an embodiment of the present invention is “purple”, the optimum water is greater than pH 5.2 and less than pH 7.0. The water electrolysis process is performed while the cut-cut part is immersed in the (+) electrode part of the electrolysis,

Each step will be described in detail as follows.

First, while the cut flower hydrangea is flower arrangement in a vase, a trace amount of sodium chloride (NaCl concentration 0.2% or less) is added to tap water, and the positive electrode (+) is applied to the part where the cut flower part of the hydrangea is submerged. The difference from “blue series” in the electrolysis process is that blue series keeps weak acidity, so it is difficult for microorganisms to propagate in water and vases, but in case of “purple series”, it is easy to reproduce because it is kept up to pH 7.0. to be. For this reason, the sterilization process must go through the sterilization process again after a certain period of time (10 to 12 hours) in the electrolysis process.

First, while the cut flower hydrangea is flower arrangement in a vase, a trace amount of sodium chloride (NaCl concentration 0.2% or less) is added to tap water, and the positive electrode (+) is applied to the part where the cut flower part of the hydrangea is submerged. Next, power is applied in the power-on step (S100).

In the step (S101) of determining whether the pH is greater than or equal to 2.2 to less than or equal to 2.7, the water is acidified and sterilized to less than or equal to 2.2 to less than or equal to 2.7, and in this process, chlorine contained in the tap water is removed.

In the step (S102) of determining whether 5 minutes have elapsed, most microorganisms in the water and in the vase are sterilized, and thus the power is cut off as the power OFF step (S103) after 5 minutes have elapsed.

Subsequently, as a step (S104) of switching the polarity of the power source (S104), the part where the cut section of the hydrangea is locked is switched from the original (+) to the negative (-) power, and the power ON step (S105) proceeds. do.

This is because water is in the range of more than 2.2 to less than 2.7, so that it is more than pH 5.2 and less than pH 7.0. Subsequently, the process proceeds to the step (S106) of determining whether the pH is greater than 5.2 to less than pH 7.0 to suit the hydrangea of "purple". If the pH exceeds 5.2 to less than 7.0, the power is cut off as the power OFF step (S107). .

Subsequently, when 10 to 12 hours or more has elapsed after the power OFF step (S107), or 10 to 12 hours have elapsed in the pH 7.0 or higher step (S108), the water becomes neutral and microorganisms begin to multiply in water and vases. In order to sterilize water by strong acidification, when 10 to 12 hours have elapsed, it proceeds to the power polarity re (+)(-) switching step (S109) to switch the power polarity, and returns to the initial power ON step (S100). It is made in the order of proceeding to the going step (S120).

In any of the above steps, the power is turned off when the vase is water exchanged or the flower arrangement is finished. The process after the step (S120) of returning to the power ON step (S100) continues to be repeated unless the vase is replaced with water or the flower arrangement is terminated.

First, while the cut flower hydrangea is flower arrangement in a vase, a trace amount of sodium chloride (NaCl concentration 0.2% or less) is added to tap water, and the positive electrode (+) is applied to the part where the cut flower part of the hydrangea is submerged. The difference from the “blue series” in the electrolysis process is that the blue series maintains weak acidity, so it is difficult for microorganisms to grow in water and vases. Microorganisms are easy to reproduce. For this reason, the sterilization process must go through the sterilization process again after a certain period of time (10 to 12 hours) in the electrolysis process.

First, while the cut flower hydrangea is flower arrangement in a vase, a trace amount of sodium chloride (NaCl concentration 0.2% or less) is added to tap water, and the positive electrode (+) is applied to the part where the cut flower part of the hydrangea is submerged. Next, power is applied in the power ON step (S130).

In the step of determining whether the pH is 2.2 or more to 2.7 or less (S131), water is acidified to a pH of 2.2 or more to 2.7 or less to sterilize, and in this process, chlorine contained in tap water is removed.

In the step of determining whether 5 minutes have elapsed (S132), most microorganisms in the water and in the vase are sterilized, and thus the power is cut off as the power OFF step (S133) after 5 minutes have elapsed.

Then, as a step of switching the polarity of the power to (-) (+) (S134), the part where the cut part of the hydrangea is locked is switched from the original (+) to negative (-) power, and the power ON step (S135) proceeds. do.

This is because water is in the range of pH 2.2 or higher to 2.7 or lower, so that it should be pH 7.0 or higher to pH 7.4 or lower. Subsequently, the process proceeds to the step (S136) to determine whether the pH is higher than 7.0 to less than pH 7.4 to suit the hydrangea of “pink and red”. If the pH is maintained above 7.0 to less than 7.4, the power is turned off as the power supply step (S137). Block.

Subsequently, in the step of determining whether 10 to 12 hours or more has elapsed after the power OFF step (S137), when 10 to 12 hours have elapsed, microorganisms begin to multiply in the water and vases, so that the water is strongly acidified to sterilize the water again. , When 10 to 12 hours have elapsed, the power polarity re-(+)(-) switching step (S139) is performed to switch the power polarity, and the initial power ON step (S130) is returned to the step (S140). It is made in order.

In any of the above steps, the power is turned off when the vase is water exchanged or the flower arrangement is finished. The process after the step (S140) of returning to the power ON step (S130) continues to be repeated unless the vase is replaced with water or the flower arrangement is terminated.

The positive (+) electrode part 51 and the negative (-) electrode part 51 are for distinguishing when DC power is first applied, and the electrodes themselves are positive (+) electrode part 51 and negative (-) electrode. It is not fixed with the part 51. That is, when the electrodes are switched, a negative (-) power is applied to the positive (+) electrode part 51, and conversely, a positive (+) power is applied to the negative (-) electrode part 51. All structures are formed in a cylindrical shape, but can be sufficiently modified depending on the shape of the vase.

In FIG. 9(a), the positive (+) and negative (-) power sources 33 are connected to the positive (+) electrode part 41 and the negative (-) electrode part 51, respectively, and FIG. 9(b) ) Indicates the power is switched on. That is, a negative (-) power supply 33 is connected to the electrode part 41, and a positive (+) power supply 33 is connected to the electrode part 51, respectively.

To switch the power, the water in the part where the cut flower of the flower arrangement is immersed must be sterilized by applying the first power, so the positive (+) electrode part 41 and the negative (-) electrode part 51 are each positive ( +) and negative (-) power supply 33 is connected, but when the sterilization is completed and the power is switched to maintain the pH suitable for the characteristics of the flower arrangement, a negative (-) power is applied to the electrode part 41. , Positive (+) power is applied to the electrode part 51.

For example, in the case of cut flowers, pH 3.5 is the most preferable, so when sterilizing a part where cut flowers are immersed, the positive (+) electrode part 41 and the negative (-) electrode are After 5 minutes of electrolysis by connecting the positive (+) and negative (-) power sources (33) to the part (51), and applying power, most of E. coli are sterilized. The power is switched to raise the pH to a suitable pH of 3.5, and a negative (-) power is applied to the electrode part 41, and a positive (+) power is applied to the electrode part 51 to perform electrolysis.
