The present invention relates to an apparatus and method for producing a functional water containing a rare useful element, in particular, selenium which can be made into functional water by ionizing the rare useful element and then going through a pH control process, a purification process and a content control process. The present invention relates to an apparatus and a method for producing functional water containing germanium or a compound thereof.

In general, domestic water such as mineral water and tap water contains trace amounts of various organic and inorganic substances that reflect the geographic or environmental characteristics of water generation. By enacting and strictly enacting the law, we protect health.

In particular, in the past, the effect of trace substances in living water on the human body was often unclear, but recent biomedical research activities have led to a clearer water quality standard for living water, and some minerals have beneficial effects on the human body. There is increasing interest in the water containing these minerals, which are more clearly identified.

Of the minerals mentioned above, rare useful elements such as selenium and germanium have been widely recognized as scientific evidences for their health-promoting effects, but because they are present only in small amounts in ore on earth, they are naturally contained. Mineral water is very limited.

Therefore, prior arts (registration numbers: 20-022198 and 10-0302277) of rare useful elements, especially selenium, germanium, or the like, have been proposed to prepare functional water useful in humans by artificially preparing them in water.

However, according to the prior art, it is very difficult to arbitrarily adjust the content of the rare useful element as well as the removal of harmful impurities that may be incorporated in the rare useful element containing treatment is unclearly mentioned, and the acidity of the functional water as the final product ( Since the presentation of pH) is not clearly distinguished, it is unclear whether the water quality standards such as harmful impurities and acidity level required by domestic water are passed.

Accordingly, the present invention is designed to solve the above-mentioned disadvantages, selenium or germanium or a compound thereof that is capable of ionizing selenium or germanium or a compound thereof and making it into a functional water through a pH control step, a purification step and a content control step It is an object of the present invention to provide an apparatus and method for producing functional water containing the same, and to be used in health functional foods including living water, bath solvents and drinking water and beverages.

Hereinafter, described in detail according to the present invention.

1 is a view showing an apparatus for producing functional water according to the present invention, an ionizer 10 for producing a ionic solution by heating and dissolving a mineral raw material containing selenium or germanium or a compound thereof, and an ionizer ( 10) Purification to neutralize the ionic solution or to adjust the pH of the pH-controlled solution prepared in a pH-controlled solution, the impurities of the pH-controlled solution charged in the pH adjusting device 20 to produce a purified stock solution Apparatus 30 and the content composition device 40 to adjust the content of the refining stock solution charged in the refining device 30 to the raw water and then to pass through a filter to produce a functional water.

The ionizer 10 is connected to the first tank 11 into which the mineral raw material is input and the second tank 12 into which the ionization solvent is input, respectively, and the pH adjusting device 20 is capable of adjusting pH such as neutralizing liquid or powder. The third tank 21 into which the additive is added is connected, and the 4.5 tank 41.42 into which the refining stock solution and the raw water (distilled water, mineral water, tap water, etc.) are respectively input to the content composition device 40 is connected.

At this time, the pH can be adjusted by adding a pH-adjustable additive according to the application of the functional water, and in the case of beverages, the pH is adjusted to 2.5 to 8.0 in consideration of the preservation and acidity, 5.0 to 9.0 in the case of a bath solvent. .

In addition, as additives for adjusting the pH, food or food additives such as citric anhydride, hydrous citric acid, malic acid, tartaric acid, lactic acid, succinic acid, vitamin C, fumaric acid, sodium citrate, sodium methiphosphate, sodium pyrophosphate and sodium benzoate The raw materials specified in the manual may be used.

Hereinafter, the manufacturing process of the functional water will be described as follows.

First, in the first step, the mineral raw material filled in the first tank 11, that is, selenium, germanium, or any one of the compounds is selected and charged into the ionizer 10, and then the ionization solvent in the second tank 12 The agent is charged into the ionizer 10 to dissolve and ionize the mineral raw material while heating.

At this time, high purity raw materials that can minimize the incorporation of impurities are advantageous as mineral raw materials, but low quality raw materials may also be used in consideration of economic efficiency such as ease of procurement. As an ionization solvent, an acid, an alkali or a pure water solution capable of dissolving selenium, germanium, and the compound thereof is selected and used.

In addition, in order to increase the dissolution rate of the mineral raw material, an acid solution is preferred for the metallic raw material, and in consideration of the dissolution rate and ease of treatment, an alkali solution or pure water is preferably used.

In addition, in order to accelerate the dissolution rate of the mineral raw material and to increase the ease of neutralization treatment by evaporating the acid and alkali groups, it is preferable to heat the solvent to a certain temperature and at the same time operate the agitator to stir.

On the other hand, in the second step, by dissolving the ionic solution charged in the ionizer 10 to a pH adjustable additive such as neutralizing solution or powder supplied from the third tank 21 at a constant temperature to produce a pH adjusted solution In this step, a pH-adjusted solution containing organic minerals such as selenium or germanium and inorganic minerals is generated.

At this time, the neutralizing solution or powder not only provides the target content of the functional water but also determines the pH of the final product (functional water). Therefore, the pH of the stock solution should be managed in an appropriate range. Selection is made in consideration of the above purpose.

In particular, when the pH adjusting solution introduced by the third tank 21 is an acidic ion solution, an alkaline pH adjusting solution such as slaked lime is used. When the neutralizing solution is an alkaline ion solution, an acidic pH adjusting solution such as hydrochloric acid is used. It is preferable to use.

Hereinafter, representative chemical reactions in the first and second steps of selenium will be described.

Stage 1; Se + H2SO4-Se ++ + 2H + + SO4--

Two steps; Se ++ + 2H + + SO4--+ Ca ++ + 2 OH- + SO4---

Se ++ + 2H2O + Ca SO4 + Organic Selenium Compound + Inorganic Selenium Compound

Meanwhile, in the third step, the impurities contained in the pH-adjusted solution charged into the purification device 30 are filtered by a filter, and finally, the purification stock solution containing the target amount of the organic or inorganic rare oil for which impurities are removed is finally targeted. It is a step of manufacturing.

At this time, the pH-controlled solution generated in the second step is added to the functional water and various biological functional products such as drinking water, bath water, and lotion, and then purified filter treatment is possible, but it is easier to remove impurities in the third step. In particular, in the case of high viscosity of the final functional product, the purified stock solution must be used to remove the impurities.

In addition, the pH of the solution is controlled by the size of the impurities according to the pore size of the filter, the pore size of the filter is recommended in the range of 0.1 ~ 20㎛. In this case, it is difficult to remove impurities having a size of 10 μm or more with a filter having a diameter of 20 μm or more, and particles of useful fine minerals are removed with a filter having a size of 0.1 μm or less, thereby reducing recovery of selenium or germanium.

On the other hand, the fourth step, by mixing the refined stock solution charged in the content composition device 40 with the raw water (distilled water, mineral water, tap water, etc.) supplied to the fifth tank 42, the target content of useful minerals according to the end use purpose This step is to prepare the final product by filtering the impurities.

In this case, in the case of selenium, the target content of the functional water can be formulated in the range of 0.001 to 0.2 ppm depending on the intended use. The reason for the limitation is that a trace content of 0.001 ppm or less makes it difficult to obtain the expected effect of selenium and 0.2 ppm or more. This is because the content exceeds the food and drug safety standards.

In addition, in the case of germanium, the target content of the functional water can be formulated in the range of 0.001 to 100 ppm depending on the intended use. The reason for the limitation is that a trace content of 0.001 ppm or less makes it difficult to obtain the expected effect of germanium and 100 ppm or more. This is because the economic loss of the functional water is lost in view of the expensive germanium cost.

At this time, the pore size of the filter is recommended to be in the range of 0.1 ~ 10㎛, it is difficult to remove impurities of more than 5㎛ size with a pore size filter of 10㎛ or more, and particles of fine minerals useful as a filter size of less than 0.1㎛ And the recovery rate is lowered.

Example 1

First, charge selenium with purity of 99.0% or more into the ionizer 10, add concentrated sulfuric acid of at least 9 normal, and heat-dissolve it at a temperature range of 50 to 180 ° C. to prepare a selenium sulfate solution in the range of sulfuric acid concentration of sulfuric acid or less. Then, charged with selenium sulfate solution into the pH adjusting device 20 and the aqueous solution of slaked lime was added to prepare a pH-controlled solution in the range of pH 5 ~ 9, and then the pH adjusted solution in the purification device 30 After charging and pressurizing with a pressurizing device, a filter having a pore size of 1.2 ± 0.8 μm was passed through the filter to prepare a refining stock solution. Then, raw water was added to the content composition device 40 to adjust the selenium content in the refining solution to 0.001 to 0.05 ppm. It is made of functional water by passing through a filter having a pore size of 0.45 ± 0.05 μm.

In this case, selenium sulfate solution was prepared by charging selenium with purity of 99.0% or more into the ionizer 10 and heating and dissolving it in concentrated sulfuric acid of 9 normal or more. This is because sulfuric acid solution having less than 9 normal sulfur has a slow dissolution rate. This is because it is suitable as a solvent.

At this time, the selenium concentration in the selenium sulfate solution is adjusted in the range below the sulfuric acid concentration of concentrated sulfuric acid. When using 9-normal concentrated sulfuric acid, the maximum amount of selenium dissolved in the selenium sulfate solution may not exceed 4.5 mol.

In addition, in order to accelerate the dissolution rate of selenium and evaporate excess acid to minimize the neutralization treatment, it was heated and dissolved at 50 ~ 180 ℃, but below 50 ℃, the dissolution rate was slow and above 180 ℃, dissolution was incomplete due to rapid evaporation of acid. It was.

In addition, 15 w / v% of the aqueous solution of slaked lime was added to the pH adjusting device 20 to adjust the selenium sulfate solution to a pH range of 5 to 9, and below pH 5, the pH of the water to be eaten when the purified stock solution was added to the raw water. The standard (pH 6.5 or more) can not be satisfied, the pH of 9 or more has a problem that the recovery of selenium is low due to excessive pH control reaction.

In addition, when the white precipitate (neutralizing solution) generated in the pH adjustment process was passed through a pore size 1.2 ± 0.8 ㎛ filter while pressurizing with a pressurizing device, and the filtrate (refining stock solution) was analyzed by the instrument, when 1 mol of selenium sulfate solution was treated. , The content of selenium was confirmed to be 500 mg / l.

In addition, 500 mg / l selenium crude solution was added to raw water of mineral water, tap water, and distilled water for the purpose of producing final selenium content of 0.010 to 0.008 mg / l functional water, followed by a pore size 0.45 ± 0.05 μm filter by a secondary pressurization device. Passed through.

In addition, 500 ml / l of purified selenium was added to the raw water of mineral water, tap water and distilled water for the purpose of producing the final selenium content of 0.05 to 0.04 mg / l functional water, and then the pore size 0.45 ± 0.05 µm by the secondary pressurization device. I passed the filter.

In addition, as a result of confirming and analyzing the content of selenium contained in the functional water through the instrument analysis, as shown in Table 1, it was confirmed that the water quality standards and food and drug safety standards required for drinking water management, respectively.

First, charged with selenium dioxide having a purity of 99.0% or more in the ionizer 10, and added pure water to dissolve it at 50 to 100 ° C. to prepare a selenium aqueous solution having a selenium concentration of 4 mol or less, and then to the pH adjusting device 20. After charging the selenium solution and adding the slaked lime solution to prepare a pH-controlled solution in the pH range of 5-9, charge the pH-controlled solution into the refining device 30 and pressurized with a pressurizing device to increase pore size 1.2 ± 0.8 After passing through the filter of μm to produce a purified stock solution, raw water was added to the content composition device 40 to adjust the selenium content to 0.001 to 0.05 ppm, and then passed through a filter having a pore size of 0.45 ± 0.05 μm. Manufactured by water.

At this time, charged with selenium dioxide with a purity of 99.0% or more in the ionizer 10 and heated and dissolved in 50 ~ 100 ℃ in pure water to prepare an aqueous solution of selenium in the range of 4 mol or less, the maximum solubility of the selenium dioxide in pure water is 4 mol. It cannot be exceeded.

Aqueous selenium solution was adjusted to pH 5-9 using 15w / v% lime solution, but below pH 5, it could not meet the pH water quality standard (pH 6.5 or higher) of drinking water when added to raw water. Due to the excessive pH control reaction is a low recovery of selenium is a problem.

In addition, by filtering the solution of the pH adjusted to pH 5 ~ 9 neutralized in the pH adjusting device 20 through a pore size 1.2 ± 0.8 ㎛ filter, and the filtrate (refining stock) was analyzed by the instrument, 1 mol selenium solution When the treatment, the content of selenium was found to contain 350 mg / l.

In addition, a selenium 350 mg / l purified stock solution was added to raw water of mineral water, tap water, and distilled water for the purpose of producing final selenium content of 0.010 to 0.008 mg / l functional water, followed by a pore size 0.45 ± 0.05 μm filter by a secondary pressurization device. Passed through.

In addition, a 350 mg / l tablet of selenium was added to raw water of mineral water, tap water, and distilled water for the purpose of producing a final selenium content of 0.05 to 0.04 mg / l functional water, and then a pore size 0.45 ± 0.05 µm filter was applied by a secondary pressurizing device. Passed through.

In addition, as a result of confirming and analyzing the content of selenium contained in the functional water through the instrument analysis, as shown in Table 2, it was confirmed that the water quality standards and food and drug safety standards required for drinking water management, respectively.

Example 3

First, charge germanium with purity of 99.0% or more into the ionizer 10, add 6-normal or more concentrated nitric acid, and dissolve it in a temperature range of 50-120 ° C. to produce a germanium nitrate solution in a range of less than nitric acid concentration of nitric acid. Then, the germanium nitric acid solution was charged to the pH adjusting device 20 and caustic soda solution was added to prepare a pH adjusted solution in the pH range of 2 to 6, and then the pH adjusted solution was purified to the purification device 30. After charging and pressurizing with a pressurizing device, a filter having a pore size of 1.2 ± 0.8 μm was passed through to prepare a purified stock solution. Then, raw water was added to the content composition device 40 to adjust the germanium content in the purified solution to 0.001 to 100 ppm. It is made of functional water by passing through a filter having a pore size of 0.45 ± 0.05 μm.

At this time, germanium nitrate solution was prepared by charging germanium with a purity of 99.0% or more into the ionizer 10 and heating and dissolving it in concentrated nitric acid of at least 6 norms. It is suitable as a solvent.

At this time, the germanium concentration in the germanium nitric acid solution is adjusted in the range below the nitric acid concentration of concentrated nitric acid. If 6-Normal concentrated nitric acid is used, the maximum germanium dissolution of the germanium nitric acid solution may not exceed 6 moles.

In addition, in order to accelerate the dissolution rate of germanium and evaporate excess acid to minimize the neutralization treatment, heat dissolution was performed at 50 ~ 120 ℃, and below 50 ℃, dissolution rate was low and dissolution was incomplete due to rapid evaporation of acid. .

In addition, the germanium nitrate solution was charged to the purification device 30 and controlled by using a 15 w / v% caustic soda solution to limit the pH to 2-6 range. When added to raw water, it was unable to satisfy the pH water quality standard of pH 5.8-8.6. At pH 6 or higher, the recovery rate of germanium is lowered by hydrolysis due to excessive pH control reaction.

In addition, a solution adjusted to pH 2-6 in the purification device 30 was passed through a pore size 1.2 ± 0.8 μm filter in the content composition device 40, and the device was analyzed by purification of the purified stock solution. The content was found to be 3.3 g / l.

In addition, the germanium 3.3g / ℓ refining stock solution was added to the mineral water, tap water and distilled water to produce a final germanium content 10 ± 2mg / ℓ functional water, and then passed through a pore size 0.45 ± 0.05㎛ filter.

Example 4

First, charge germanium dioxide with purity of 99.0% or more into the ionizer 10, add caustic soda solution of 2 normal or more, and dissolve it by heating to 50-120 ° C., and the germanium concentration is within 40% of the sodium hydroxide concentration. After the solution was prepared, the germanium caustic soda solution was charged into the pH adjusting device 20 and 6-9 normal hydrochloric acid was added to prepare a solution having a pH adjusted from 10 to 12.5, and then to the purification device 30. Charge the pH-adjusted solution and pressurize it with a pressurizing device to make a purified stock solution by passing through a filter of pore size 1.2 ± 0.8㎛, and then add raw water to the content composition device 40 to determine the germanium content in the purified solution 0.001. After adjusting to -100 ppm, it is made into functional water through the filter of pore size 0.45 +/- 0.055micrometer.

At this time, the germanium caustic soda solution was prepared by charging germanium dioxide with purity of 99.0% or more in the ionizer 10 and heating and dissolving it in caustic soda solution of at least 2 norms. The above caustic soda solution is suitable.

At this time, the germanium concentration in the germanium caustic soda solution is adjusted in the range of 40% or less of the caustic soda concentration. When using a two-normal caustic soda solution, the maximum germanium dissolution of the germanium caustic soda solution may not exceed 0.8 mol.

In addition, in order to accelerate the dissolution rate of germanium dioxide, the mixture was stirred while heating and dissolving at a temperature in the range of 50 to 120 ° C., but the dissolution rate was low at 50 ° C. or lower and incomplete dissolution due to the rapid evaporation of water at 120 ° C. or higher.

In addition, after preparing the germanium caustic soda solution in the ionizer 10, it was controlled to limit the pH to 10 ~ 12.5 range using hydrochloric acid of 6 or more normal, when the pH is less than 10, the dissolved germanium is precipitated by hydrolysis. There is this.

Accordingly, care must be taken in adjusting the pH of the germanium caustic soda solution. When the pH exceeded 12.5, when the purified stock solution was added to the raw water, the pH of the bath was not satisfied with pH 5.8-8.6.

In addition, the solution adjusted to PH 10 ~ 12.5 was passed through a pore size 1.2 ± 0.8 μm filter through a pressurizing device, and the filtrate (refining stock solution) was analyzed by instrument. As a result, 1 mole of germanium caustic soda solution (4 normal caustic soda solution) It was confirmed that the germanium content was 6.2 g / L.

In addition, the germanium 6.2g / ℓ purified liquid was added to the raw water of mineral water, tap water and distilled water for the purpose of producing a final germanium content 10 ± 2mg / ℓ functional water, and then passed through a second pore size 0.45 ± 0.05㎛ filter.

In addition, as a result of confirming the germanium content in the functional water through the device analysis, as shown in Table 4, it was confirmed that the functional water passed the water quality level required by the bath water management.

Example 5

First, charge germanium dioxide with a purity of 99.0% or more into the ionizer 10, add 6 normal or more hydrochloric acid solution and dissolve it by heating and dissolving it at a temperature range of 50-80 ° C. as a germanium hydrochloric acid solution in the range below the concentration of hydrochloric acid. After the preparation, the germanium hydrochloric acid solution was charged to the pH adjusting device 20 and caustic soda solution was added to prepare a solution having a pH adjusted in the range of pH 2 to 6, and then the pH adjusted solution in the purification device 30. Was charged and pressurized with a pressurizing device to produce a purified stock solution by passing through a filter having a pore size of 1.2 ± 0.8 μm. Then, raw water was added to the content composition device 40 so that the germanium content in the purified liquid was 0.001 to 100 ppm. After the adjustment, a filter having a pore size of 0.45 ± 0.05 μm was passed through to produce functional water.

At this time, germanium dioxide having a purity of 99.0% or more was charged to the ionizer 10, and dissolved by heating in a solution of 6 normal or more hydrochloric acid, thereby preparing a germanium hydrochloric acid solution. It was found that this is suitable.

At this time, the germanium concentration in the germanium hydrochloric acid solution is adjusted in the range below the concentration of hydrochloric acid. When 6-normal hydrochloric acid is used, the maximum selenium dissolution of germanium hydrochloric acid cannot exceed 6 mol.

In addition, in order to minimize volatilization as a chloride in the form of germanium chromide, heat dissolution was carried out at a temperature range of 80 ° C. or lower. At a temperature below 50 ° C., the dissolution rate was low, and germanium was volatilized as mentioned above at a temperature above 80 ° C. Recovery is too low.

In addition, the germanium hydrochloric acid solution was reacted with 15 w / v% caustic soda solution to adjust the pH to 2 to 6 range. Under pH 2, when the purified stock solution was added to the raw water, pH 5.8 to 8.6 It was not possible to satisfy the problem, and at pH 6 or higher, the recovery rate of germanium is low due to hydrolysis due to excessive pH control reaction.

In addition, after adjusting the pH of the solution adjusted to pH 2 ~ 6 through a pore size 1.2 ± 0.8 ㎛ filter, the filtrate (refining stock) was analyzed by the instrument, it was confirmed that the germanium content of 2.5g / ℓ for 1 mol germanium hydrochloric acid solution . The germanium 2.5 g / L purified stock solution was added to the raw water of mineral water, tap water, and distilled water for the purpose of preparing a final germanium content of 10 ± 2 mg / L functional water, and then passed through a pore size 0.45 ± 0.05 μm filter to remove impurities.
